light sensors

Lighting Sensors | The ultimate way for Energy Saving

Whenever we talk about energy saving we always talk about changing our daily habits, and go for energy efficient appliances. But in this modern era of technology where we have more than just bulbs and lights, then why only stick to the old traditional ways. It’s time that we should expand our vision and look for some other alternative which can give us more efficient output.

Lighting Sensors

The ultimate solution for using light only when needed is – Lighting sensors. Lighting sensors help you everyday by detecting and reacting to different levels of light in appliances, switches and machines. 

The light sensor is a passive device that convert this “light energy” whether visible or in the infra-red parts of the spectrum into an electrical signal output. Light sensors are more commonly known as “Photoelectric Devices” or “Photo Sensors” because the convert light energy (photons) into electricity (electrons).

Motion Sensitive Light Switches

One such product which has caught our attention and gained a lot of popularity over the past few years is motion sensor light switches. Motion sensor light switches turns on when they sense someone in the room and are switched off after a certain amount of inactivity. Motion sensors reduce electricity consumption by eliminating the possibility that the lights will accidentally be left on.

You see them more and more in corporate and public spaces, because they are convenient for employees and shut off after continued inactivity, significantly reducing energy expenses.

In order to detect the presence of a human being inside a room properly, the motion sensor can take advantage of several types of technologies – 

Pyroelectric Sensor – It measures the infrared radiation, and since everything emits a certain level of IR radiation, it is quite easy to detect major fluctuations emitted when a person passes by. The disadvantage is that the sensor will detect only significant movements and only in direct line of sight.

Ultrasonic Technology Sensor – This sensor uses the ultrasonic technology in order to detect smaller changes into the environment so the light doesn’t turn off when you’re reading a book or typing on the computer keyboard. To accomplish it, the sensor sends a small pulse into the room, which returns and allows the device to detect any changes. The disadvantage is that it can be prone to false detection and it draws more power.

Motion sensor light switches reduces energy consumption by 35-45 percent, and can go up to as high as 75 percent. 

Conclusion – 

Changing the light switches is a minor project, but one that can be incredibly convenient – not having to worry about turning off the lights when you are gone, especially in places that are frequently used, eliminates a common habit that many wish they could get a hold of.

insulation

Role of Insulation in Buildings !

Insulation refers to an energy savings measure, which provides resistance to heat flow. Naturally, heat flows from a warmer to a cooler space. By insulating a house, one can reduce the heat loss in buildings in cold weather or climate, and reduce the heat surplus in warmer weather or climate. Insulating a house has several benefits such as energy savings, cost savings and increased comfort. Barriers to undertake energy savings measures may be split incentives, relatively high investment costs, and the time and effort required to realise the energy savings. There are several types of insulation against heat loss in cold climates, each with its own technical characteristics and financial costs and benefits. Insulation measures are generally one of the most cost effective energy savings measures.

 

Introduction 

By insulating a house, one can reduce the heat loss in buildings in cold weather or climate, and reduce a heat surplus in warmer weather or climate. Thus, insulation limits the need for heating or cooling the house. Heat losses or heat surpluses arise because of differences between the indoor and outdoor air temperature. Naturally, heat flows from a warmer to a cooler space, and the temperatures will converge to an equilibrium temperature, a physical phenomenon based on mechanisms like transmission (the heat flow through materials) and ventilation (heat flow by air). Insulation aims at reducing the speed of this convergence of temperature in order to decrease the need for heating or cooling.

This technology description focuses on insulation against heat loss, but includes some references on insulation for cooling.

Several types of insulation measures exist. Below insulation measures for residential buildings are described:

Wall, roof and attic, floor and soil insulation

Wall, roof and floor insulation may be done by fixing insulation material to the wall, roof or floor, either on the inside of outside, e.g. by using insulation plates. Different materials for walls, roofs and floors require different types of insulation measures. Buildings may for example have cavity walls consisting of two ‘skins’ separated by a hollow space. This space already provides some insulation but can be filled up with additional insulation material, e.g. foam, to further improve the insulation effect. Roof insulation for flat roofs differs from insulation for steeper roofs.

Floors are usually made of wood or concrete, each requiring specific insulation measures. Another option to reduce heat losses to the ground is soil insulation, for example by placing insulation material on the soil in a so-called “crawl space” (a very low basement).

The age of a building is an important factor determining the type of insulation and the way in which it is installed, e.g. if insulation is put on the outside or inside of the construction.

Window and door insulation

Windows and exterior doors have a large impact on the heating and cooling requirements of a building. New materials, coatings, and designs have led to significantly improved energy efficiency of new, high-performing windows and doors. New high-quality windows may be up to six times more energy efficient than lower-quality, older windows (Pew Centre, 2009). Some of the latest developments concerning improved windows include multiple glazing, the use of two or more panes of glass or other films for insulation, and low-emissivity coatings reducing the flow of infrared energy from the building to the environment (Pew Centre, 2009). Attention needs to be paid not only to the window itself, but also to the window frame, which can significantly impact a window’s insulation level.

Sealing cracks

Another insulation measure that reduces the amount of heat loss is sealing cracks in the ‘shell’ of the building. Cracks cause infiltration of cold air from outside or leakage of warm air to the outside. Strips or other material can be used to seal cracks in moving parts, such as windows and doors, and in places where different construction parts are attached to each other.

Feasibility of technology and operational necessities : 

Increasing insulation is technically feasible for almost all buildings, although it is most efficient to add insulation during the construction phase. Because of the diversity of insulation measures, a suitable option is generally available for almost every building, since most buildings have room for improvement with respect to insulation. Next to technical requirements, human preferences regarding comfort and aesthetics also play a role, e.g. for windows better insulation comes with lower insolation, i.e. less light.

In practice, the suitability of insulation measures depends largely on the current technical state of a dwelling. Specifically the insulation already in place limits additional insulation. This is due to the physical space left for insulation and the suitability of the existing construction (e.g. availability of a cavity wall or sufficient cavity width, enough frame space to install better insulated but usually thicker windows, enough crawl space under the floor), but also because the law of diminishing returns applies: Every additional layer of insulation yields less energy savings than the previous one.

The level of insulation that can be achieved by different insulation materials, i.e. the insulation value, is typically expressed as the R-value. The R-value indicates the insulation material’s resistance to heat flow. The higher the R-value, the better the insulation of a wall, roof or floor. For windows the value U is used, mathematically different but analogue to the R-value. Opposite to the R-value, the lower the U value the better the insulation of the window.

Status of the technology and its future market potential  

Insulation measures against heat loss are common practice in countries with frequent cold weather, where they are applied at the construction of new buildings, but also during the renovation of buildings. Older buildings commonly have a much lower level of insulation than newer ones, which in OECD countries are typically built according to the latest energy performance regulations. A large technical potential remains to improve insulation levels of the existing building stock using mature technologies. Many insulation measures would also be cost-effective due to savings in energy costs.

In the US, for example, more than 60% of single-family, residential houses are estimated to be “under-insulated”, i.e. by improving the level of insulation home owners could save costs, avoid GHG emissions, and improve indoor climate. In India only 5 % buildings are using Building Insulation and mostly for HVAC purposes

Common barriers why these measures are not implemented include: high initial investment costs, lack of financing options for the up-front investments, the time and effort required to undertake renovation measures in existing buildings, relatively long payback times for some measures, lacking knowledge and awareness, and split incentives, i.e. the decision makers who can / must decide on the level of insulation in a building and pay for the higher upfront costs are not the same persons who will reap the benefits of lower energy costs for heating and/or cooling.

Governments of India have introduced measures to reduce these barriers, including mandatory energy efficiency standards, building certification, voluntary labelling, and financial incentives to stimulate investments into increased insulation and other energy saving measures in buildings. Moreover governments, civil society and industry organisations use information campaigns to increase awareness and knowledge of energy saving options in buildings. In India MNRE & BEE (Bureau of Energy Efficiency) the main regulatory framework to prescribe the use of energy labels for Energy Efficient buildings in India and also it is a requirement in the recent launched Energy Conservation Building Code – 2017 by BEE.

How the technology could contribute to socio-economic development and environmental protection 

Insulation leads to energy savings, which reduce the demand for fossil fuels and associated GHG emissions and other environmental impacts. It is estimated that improvements in the level of insulation of the existing building stock can reduce heating requirements by a factor of two to four. New houses built according to the latest available technology and design in various cold-climate countries use as little as 10% of the energy for heating than houses built according to the local national building codes.

For countries with milder winters, where heating is still required, as is the case in many developing countries, modest levels of insulation at a reasonable cost may already reduce the heating requirements by more than half of current levels, and in addition may contribute to reducing indoor temperatures in summer. If there is no air conditioning, lower temperatures in summer improve indoor comfort, or, if air conditioning is used, lead to additional energy savings.

fire extinguisher

Fire Safety & Security – An Unavoidable Practice in the field of Construction

When we hear term Fire Safety, we only thought of the Fire Extinguishers and Fire Fighting officers , But Fire Security & Safety is much more than that.

INTRODUCTION

A fire can happen at any time at any place irrespective of its occupancy status. You can expect a fire at any structure, may be at your home or at your workplace or in a hospital or in public places like theatres, malls, etc… Fire in any occupancy has the potential to cause harm to its occupants and severe damage to property.

On an average, in India, every year, about 50,000 persons die due to fires and related causes. Female accounts for about 66% of those killed in fire accidents. It is estimated that about 42 females and 21 males die every day in India due to fire. According to the statistics released by the National Crime Records Bureau, fire accounts for about 5.9% (23,281) of the total deaths reported due to natural and un-natural causes during the year 2012. Probably many of these deaths could have been prevented, had we taken enough fire protection measures.

No comprehensive data is available in India on the economic losses suffered on account of fires. However, according to one estimate the major losses reported by the Indian Insurance Companies in the year 2007-2008 indicate, that about 45% of the claims are due to fire losses. According to another estimate about Rs. 1000 crores are lost every year due to fire. Fire losses are reported both in industrial and non-industrial premises like hospitals, commercial complexes, educational institutions, assembly halls, hotels, residential buildings, etc… According to Fire Risk Survey (FRS) 2013, carried out by Pinkerton & Federation of Indian Chambers and Industry, in India, fire accounted for 8.45% of the overall ranking of risks. FRS also revealed that fires has been rated as the 5th highest risk in industry in 2013.

The above survey also revealed that in industry wise risk ranking, fire take 2nd place in hospitality, 4th place in IT/ITES, Manufacturing, Security Service Providers and 6th place in infrastructure. As far as the leading cause for the fire is concerned, according to the survey, the electric defaults are regarded as the major cause of fires. In Mumbai about 75% of fire-related incidents occur because of short circuit caused by loose wiring.

The survey also point out that during the period 2009-2012, Mumbai fire department had attended 13,185 incidents of fire out of which 9711 were caused due to defective electric circuit. The scenario for other major cities are also not different.

THE PROBLEM

For mitigating a fire in any occupancy, whether it is a business house or in a factory or in a residential building, require a deep understanding about the problem.

A small fire in a residential building may be spread very fast and within a few minutes it can reach a stage beyond the control of its occupants and ultimately seek the help of fire brigade to carry out a major firefighting operation. During the last one decade there was a vibrant growth in the constructions activities in India, especially in High Rise buildings. Thousands of High Rise buildings have already constructed in metros and major cities in India, and thousands are under construction. Because of its peculiar nature, fire in residential buildings in particular, high rise buildings become more complex and the salvaging operations become more difficult and sometimes even resulting in many deaths and huge property losses.

In an era of highly competitive business environment any interruption due to fire can be catastrophic. A major fire can bring a business to halt. Restoring the damage done by fire is only part of the cost of fire. A fire may have serious consequences for the production capacity of a business and in the extreme, the time taken to restore production may be such that the business is forced to close down altogether.

A fire can, not only interrupt the whole process of manufacture and production, bwut also the building and plant will be in ruins. Before they can be replaced and production restored, much work in clearing up the site will be necessary. It will also be necessary to determine what has been lost and damaged. Even if only a small part of the plant has been involved in the fire, staff from other work will need to be diverted to clear up the mess and to plan the rebuilding and restoration of production.

One must admit that fire creates total waste. Such waste would not be tolerated by any efficient management, if it resulted from inefficient operation. The successful prevention of fire loss depends almost entirely on the management of the business. To control the loss through fire, the management must survey the total operation of the business to determine where the loss potential lies.

One must also admit that the fires are caused almost entirely by people, either through their actions, which may be accidental or deliberate and malicious or through their failure to make appropriate precautions such as, for example, the regular inspection, maintenance and repair of defective equipment.

Inadequately maintained machines can be fire prone. The overheating of bearing, due to insufficient lubrication or the presence of dust, and heat caused by friction are common causes of fire. Frequent inspection and regular maintenance will reduce risk and make the general tidiness of premises easier to achieve.

Remember that fires start when source of ignition comes into contact with combustible material. If you can control all sources of ignition and combustible material, you can greatly reduce the potential for fire.

You should also remember that waste and rubbish are friends of fire. Shop floors and offices can have substantial quantity of inflammatory materials such as oil soaked rags, loose packing materials, piles of papers, cartons, etc. All these materials, if ignited, will encourage fire to spread rapidly. Volatile chemicals and explosives pose serious problems. Although the paint, lacquer, flammable solvents and thinners are a less recognised hazard, negligence in handling them may result in fires. Handling small quantities of flammable liquids is a frequent causes of fires and injuries.

Heating and lighting systems that are inadequately maintained or safeguarded present risks. Many fires occur from electrical faults or misuse. Smoking is a notorious fire risk. It should be prohibited in all areas where it is especially dangerous.

Major fires start in storage area and warehouses than production areas. Poorly stored goods, even though they are not flammable, may help to spread fire and hinder fire fighters gaining access to the seat of the fire or reduce the effectiveness of sprinkler systems. Goods tidily stored with gangways may help to inhibit the spread of fire.

PREVENTION STRATEGY

An effective fire prevention strategy is an essential feature of fire protection. However, it must be kept in mind that regardless of the efficiency of a fire prevention strategy, some fires inevitably occur.

There exists large number of different types of firefighting equipment and suppression systems like CO2, FM 200, and NOVEC, to suit specific requirements. Automatic fire sprinklers coupled with detection are the most effective fire protection system found in High Rise buildings which can, not only detect the fires, but also extinguish the fires in the initial stage itself. Application of Water Mist in various situation is gaining momentum every day. Passive fire protection system is also becoming more and more popular in India.

In spite of all technical advances, water is the cheapest, most efficient and environmentally friendly fire extinguishing medium. Water, which has high latent heat of vaporization, is the most effective coolant and protection agent. No amount of appliances or equipment would be of much use, if sufficient quantities of water under required pressure were not available for firefighting. To be effective, it must be applied in sufficient quantity and at such a rate that it well prevent the accelerating growth of the fire. It must be remembered that if remedial measures are not taken in the very early stages of following the outbreak of a fire, the amount of water required increases exponentially as the increase in the time taken for the fire fighting forces to reach the scene of the fire and start effective firefighting operations.

It is estimated that a fire discovered within two or three minutes of its outbreak may be extinguished with less than 1000 litres of water. However, if the water is not applied until 5 to 10 minutes later, which is probably the shortest time in which a fire brigade may reach the scene of the fire, the fire will have grown to such proportions that between 50 to 100 times as much water may be needed for extinguishing the fire.

The successful use of any type of fire equipment depends upon the elements such as equipment, maintenance and training.

It is vital that an occupier ensures, its employees are trained for and understand what is required during an outbreak of fire. It must be remembered here that inappropriate use of water to fight a fire has even caused much damage.
It was observed that lack of knowledge in the area of fire and inadequate training in emergency drills, delay the firefighting operations. Probably adequate fire safety training and periodic emergency drills can make the emergency response more effective.

Training the employees / occupants and fire drills are clearly related but are not synonymous and it is a common misconception that conducting periodic fire drills discharge an occupier’s training obligations. No doubt fire drills are very valuable exercise but taken in isolation, they are insufficient in educating employees / occupants in all the important matters.

Training of employees / occupants in fire safety matters continues to be a controversial issue with many occupiers adopting the attitude that it is not reasonably practicable to provide training for all employees / occupants. This stance has probably never been fully tested legally. However, many occupiers take fire training seriously and train a large number of their employees / occupants.

LEGISLATIONS

The legislations, standards and codes have a vital role in forcing the occupiers to provide the required fire protection system, both active and passive. The National Building Code of India, 2005, is the basic model code in India on matters relating to building construction and fire safety. Many of the code provisions has been incorporated by various State Governments and Local Bodies in their own building regulations.

The Maharashtra Fire Prevention and Life Safety Measures Rules 2009, framed under the Maharashtra Fire Prevention and Life Safety Measures Act 2006, is an example to this, and is aimed to improve the status of fire safety measures in Maharashtra. Often a question has been raised by many that who will be responsible for providing the required fire protection and prevention system in a building or in an occupancy.

The acts and rules enacted by the State of Maharashtra has well defined on these points. According to Section 3 of the Maharashtra Fire Prevention and Life Safety Measures Act, 2006, the developer, owner, occupier or whatever name called shall comply with all the fire and safety measures adhering to the National Building Code of India, 2005, and as amended from time to time, failing which it shall be treated as a violation of the Act. It means that the onus of maintaining the fire safety installations in a building or in an occupancy is the responsibility of the owner or occupier.
In India, although there are many rules and regulations, codes and standards related to fire safety, these are seldom followed. Laxity in following fire safety measures caused major fires in many buildings. Some of the fire authorities in India even felt that in the absence of heavy fines and penalties, occupiers or societies do not bother to conduct regular maintenance of the fire prevention systems installed in their buildings.

Probably this was one of the reasons behind in incorporating a provision about ‘Licensed Agency’ in the Maharashtra Rules. As per the section 3(3) of the Maharashtra Fire Prevention & Life Safety Measures Act, 2006 and Rule 4 (2) of Maharashtra Fire Prevention & Life Safety Measures Rule, 2009, a licensed agency is required to issue a Certificate regarding the work executed by them is in compliance in relation to Fire Prevention & Life Safety Measures in Form ‘A’ and Six monthly Certificate in Form ‘B’ in every January & July to the owner or the occupier for compliance of the Fire Prevention & Life Safety Measures duly installed by them in the buildings or premises are maintained in good repair and efficient condition at the time of issuing certificate.

FIRE SAFETY AUDIT

Fire Safety Audit is found to be an effective tool for assessing fire Safety standards of an organization or an occupancy. In other words, it is aimed to assess the building for compliance with the National Building Code of India, relevant Indian Standards and the legislations enacted by State Governments and Local Bodies, on fire prevention, fire protection and life safety measures.

Though a comprehensive fire safety audit can address the inherent fire hazards associated with the day to day activities in an occupancy and recommend measures to reduce the potential fire hazards, there is no clear cut provisions in any of the safety legislations in India regarding the scope, objectives, methodology and periodicity of a fire safety audit.

However, NBC of India recommends for periodical fire safety inspection by the key personnel of the occupants of the building to ensure fire safety standards. In case of industrial building, the statutory authorities insist for fire safety audit by external agencies depending on the type of activity and the nature of the materials handled in the building. Maharashtra Fire Prevention and Life Safety Measures Rules, 2009, made it mandatory for building owners and residents to conduct half-yearly fire safety audits and submit the report to the fire department.

It is a good measure and other states too can follow this. However, entrusting the responsibility of conducting the fire safety audit to the “licensed agencies”, has created some confusions, because the same agency has also been entrusted with the work of “installations” and “maintenance” of firefighting systems. Perhaps this arrangement has resulted in diluting the scope and methodology of the audit. It is also doubtful whether the so called “licensed agencies” have the required calibre / expertise in conducting an effective fire safety audit. So in effect, it seems that the fire safety audit has become a ritual.

Recommendations

A fire can happen at any time at any place. It creates total waste. It has the potential to cause harm to its occupants and severe damage to property.

In India, fire accounts for about 5.9% of the total deaths reported due to natural and un-natural causes during the year 2012. The fires has been rated as the 5th largest risk in Indian industry. Electrical defaults are the major causes of fires in India. Therefore proper attention must be paid to minimize fire loss because ultimately the community at large has to bear all the losses.

The use of smoke detectors, fire alarms, automatic sprinklers, water mist systems, clean agent suppression system, should be encouraged, especially in high rise buildings. Passive fire protection system should have major role in fire protection.

In India, although there are many rules and regulations, codes and standards related to fire safety, these are seldom followed. Laxity in following fire safety measures caused major fires in many buildings. Though fire safety audit is found to be an effective tool for assessing fire safety standards of an occupancy, there is no clear cut provisions in any of the safety legislations in India, regarding the scope, objective, methodology and periodicity of a fire safety audit. Therefore, Fire Safety Audit should be made mandatory for all over India and the work should be entrusted to independent agencies, who have expertise in it. It is reasonable to have a fire safety audit in every year.

Above all the success of fire prevention and fire protection mainly depend upon the active co-operation from all personnel in an occupancy.

What exactly Energy audit is and the benefits Involved with it

A Energy Audit for a Building is a service where the energy efficiency of a Building is evaluated by a person using professional equipment (such as blower doors and infrared cameras), with the aim to suggest the best ways to improve energy efficiency in heating and cooling the house.

An energy audit of a home may involve recording various characteristics of the building envelope including the walls, ceilings, floors, doors, windows, and skylights. For each of these components the area and resistance to heat flow (R-value) is measured or estimated. The leakage rate or infiltration of air through the building envelope is of concern, both of which are strongly affected by window construction and quality of door seals such as weather stripping. The goal of this exercise is to quantify the building’s overall thermal performance. The audit may also assess the efficiency, physical condition, and programming of mechanical systems such as the heating, ventilation, air conditioning equipment, and thermostat.

A energy audit may include a written report estimating energy use given local climate criteria, thermostat settings, roof overhang, and solar orientation. This could show energy use for a given time period, say a year, and the impact of any suggested improvements per year. The accuracy of energy estimates are greatly improved when the homeowner’s billing history is available showing the quantities of electricity, natural gas, fuel oil, or other energy sources consumed over a one or two-year period.

Some of the greatest effects on energy use are user behaviour, climate, and age of the Building. An energy audit may therefore include an interview of the Building owner to understand their patterns of use over time. The energy billing history from the local utility company can be calibrated using heating degree day and cooling degree day data obtained from recent, local weather data in combination with the thermal energy model of the building. Advances in computer-based thermal modelling can take into account many variables affecting energy use.

A Energy audit is often used to identify cost effective ways to improve the comfort and efficiency of buildings. In addition, homes may qualify for energy efficiency grants from central government.

Recently, the improvement of smartphone technology has enabled homeowners to perform relatively sophisticated energy audits. This technique has been identified as a method to accelerate energy efficiency improvements.

During an Energy Audit Equipments & instruments that are required are ultrasonic flow meter, anemometers, lux meters, DP manometers, temperature sensors, power analyzer and HOBO loggers to work at multiple sites simultaneously. We perform energy audit services for all types of HVAC systems, chiller plants, boiler plants, steam systems, compressed air pneumatic systems, refrigeration systems, lighting and electrical systems.

An energy audit is recommended to determine the energy consumption associated with a facility and the potential savings associated with that energy consumption.

From a general point of view, an energy audit provides enormous benefits in different areas:

  • It helps reduce energy costs in your facility.
  • With a reduction in production costs, the competitiveness of your company will be improved.
  • It helps reduce the dependence on foreign energy sources.
  • It helps reduce environmental damage and pollution.
  • It can increase the security of your energy supply.
  • It can reduce the consumption of natural resources.
  • It can reduce damage to the environment associated with the exploitation of resources.
  • It helps reduce the impact of greenhouse gas emissions.

At a particular level, among the major benefits of doing an energy audit are:

  • It helps you to lower energy bills.
  • It enables you to increase the comfort of those in the facility.
  • It helps you to increase the life span of the equipment in your facility.
  • It discovers any unaccounted consumption that may exist at the facility.

In summary, an energy audit can identify energy consumption and energy costs of the facility and it can evolve over time to develop measures to eliminate waste, maximize efficiency and optimize supply energy.

The energy audit affects three key factors:

  • profitability through optimization of energy expenditure
  • productivity through optimization of equipment and processes
  • performance, thanks to the rationalization of energy use.
Indoor Air Pollution

Impact of Indoor Air Pollution in Buildings & need to improve the Indoor Air Quality

Indoor Air Quality (IAQ) refers to the air quality within and around buildings and structures, especially as it relates to the health and comfort of building occupants. Understanding and controlling common pollutants indoors can help reduce your risk of indoor health concerns.

Health effects from indoor air pollutants may be experienced soon after exposure or, possibly, years later.

Immediate Effects

Some health effects may show up shortly after a single exposure or repeated exposures to a pollutant. These include irritation of the eyes, nose, and throat, headaches, dizziness, and fatigue. Such immediate effects are usually short-term and treatable. Sometimes the treatment is simply eliminating the person’s exposure to the source of the pollution, if it can be identified. Soon after exposure to some indoor air pollutants, symptoms of some diseases such as asthma may show up, be aggrevated or worsened.

The likelihood of immediate reactions to indoor air pollutants depends on several factors including age and preexisting medical conditions. In some cases, whether a person reacts to a pollutant depends on individual sensitivity, which varies tremendously from person to person. Some people can become sensitized to biological or chemical pollutants after repeated or high level exposures.

Certain immediate effects are similar to those from colds or other viral diseases, so it is often difficult to determine if the symptoms are a result of exposure to indoor air pollution. For this reason, it is important to pay attention to the time and place symptoms occur. If the symptoms fade or go away when a person is away from the area, for example, an effort should be made to identify indoor air sources that may be possible causes. Some effects may be made worse by an inadequate supply of outdoor air coming indoors or from the heating, cooling or humidity conditions prevalent indoors.

Why are people suddenly talking about IAQ?

The reason is indoor air quality in India; especially Delhi has become very poor. Over a million people in India die every year because of indoor air pollution, among st the highest in the world. Unlike many western countries, India does not have any norm for indoor air pollution, which mandates emission norms for home appliances such as refrigerators, air-conditioners and bread toasters and a limit beyond which dirty air inside homes can be bad for one's health. The World Health Organisation (WHO) warned that healthier homes and workplaces could prevent around 1 million deaths, globally, a year, and explicitly singled out indoor air quality as a factor.

Factors Affecting Indoor Air Pollution

Much of the building fabric, its furnishings and equipment, its occupants and their activities produce pollution. In a well functioning building, some of these pollutants will be directly exhausted to the outdoors and some will be removed as outdoor air enters the building and replaces the air inside. The air outside may also contain contaminants which will be brought inside in this process. This air exchange is brought about by the mechanical introduction of outdoor air (outdoor air ventilation rate), the mechanical exhaust of indoor air, and the air exchanged through the building envelope (infiltration and exfiltration).

Pollutants inside can travel through the building as air flows from areas of higher atmospheric pressure to areas of lower atmospheric pressure. Some of these pathways are planned and deliberate so as to draw pollutants away from occupants, but problems arise when unintended flows draw contaminants into occupied areas. In addition, some contaminants may be removed from the air through natural processes, as with the adsorption of chemicals by surfaces or the settling of particles onto surfaces. Removal processes may also be deliberately incorporated into the building systems. Air filtration devices, for example, are commonly incorporated into building ventilation systems.

Managing the Indoor air Quality in Buildings

Remodeling and Renovation

  • Use effective strategies for material selection and installation.
  • Isolate construction activity from occupants.

Painting

Establish a protocol for painting and insure that the protocol is followed by both in-house personnel and by contractors.

  • Use low VOC emission, fast drying paints where feasible.
  • Paint during unoccupied hours.
  • Keep lids on paint containers when not in use.
  • Ventilate the building with significant quantities of outside air during and after painting. Insure a complete building flush prior to occupancy.
  • Use more than normal outside air ventilation for some period after occupancy.
  • Avoid spraying, when possible.

Pest Control Integrated Pest Management

  • Use or require the use of Integrated Pest Management by pest control contractors in order to minimize the use of pesticides when managing pests.
  • Control dirt, moisture, clutter, foodstuff, harborage and building penetrations to minimize pests.
  • Use baits and traps rather than pesticide sprays where possible.
  • Avoid periodic pesticide application for “prevention” of pests.
  • Use pesticides only where pests are located.
  • Use pesticide specifically formulated for the targeted pest.
  • Apply pesticides only during unoccupied hours.
  • Ventilate the building with significant quantities of outside air during and after applications.
  • Insure a complete building flush prior to occupancy.
  • Use more than normal outside air ventilation for some period after occupancy.
  • Notify occupants prior to occupation.
  • If applying outside, keep away from air intake.

Establish and Enforce a Smoking Policy

Environmental tobacco smoke (ETS) is a major indoor air contaminant. A smoking policy may take one of two forms:

  • A smoke-free policy which does not allow smoking in any part of the building.
  • A policy that restricts smoking to designated smoking lounges only.

Managing Moisture and Mold

Mold thrives in the presence of water. The secret to controlling mold is to control moisture and relative humidity

  • Keep relative humidity below 60% (50%, if feasible, to control dust mites)

Keep all parts of the building dry that are not designed to be wet

  • Adequately insulate exterior walls or ceilings to avoid condensation on cold surfaces
  • Insulate cold water pipes to avoid sweating
  • Clean spills immediately. Thoroughly clean and dry liquid spills on porous surfaces such as carpet within 24 hours, or discard the material
  • Do not allow standing water in any location
  • Maintain proper water drainage around the perimeter of the building
  • Provide sufficient exhaust in showers or kitchen areas producing steam

Thoroughly clean areas that are designed to be wet

  • Wash floors and walls often where water accumulates (e.g., showers)
  • Clean drain pans often and insure a proper slope to keep water draining
  • Insure proper maintenance and treatment of cooling tower operations

Discard all material with signs of mold growth

  • Discard furniture, carpet, or similar porous material having a persistent musty odor
  • Discard furniture, carpet, or similar porous material that has been wet for more than 24 hours
  • Discard ceiling tiles with visible water stains

Conclusion

The direct impact of indoor air quality will not be readily apparent. It could be long to see a statistical change. But one thing we keep in mind that “People have the right to breathe clean and safe air everywhere”.
