Govt. Involves to Make Sustainable Cooling Hubs for Communities

Experts from the University of Birmingham are to work with groups in India to explore how sustainable cooling can help Indian farming communities.

Launching the project on World Refrigeration Day (June 26) with a workshop in New Delhi, sustainable cooling experts will look at ways to reduce food waste, increase farmers’ income and meet rural communities’ cooling needs in an affordable and sustainable way. It intends to begin by developing ways of integrating food cold chains with other cold-dependent services such as community health facilities, social facilities such as creches and even emergency services.

Researchers from the Birmingham Energy Institute, Heriot-Watt University in Edinburgh, and the Centre for Environment Education (CEE) in India are supported by the Shakti Foundation and will join efforts with India’s National Centre for Cold-chain Development (NCCD) in this new project.

Representatives from Government, farming communities, NCCD and agri-business will take part in the one-day event to kick off the programme to deliberate on the concept of Community Cooling Hubs. A second event is being held in Pune to engage with farmer and civil society organisations.

The participants believe that creating Cooling Hubs as business units could meet the livelihood, nutrition, employment, and education requirements of the communities. Using appropriate technology and business models, it says, will help to remove barriers that stop subsistence farmers from using temperature-controlled logistics. These Hubs can also be deployed to provide the local community access to other refrigeration dependant services.

With up to 40% of food in India lost post-harvest because of lack of cold chain, the University of Birmingham is proposing a radical approach to cooling provision, where cold chains meet the wider community’s cooling needs in a clean, affordable and sustainable way. 

“Cooling hubs could support farmers, whilst ensuring that communities have continuing access to life-saving medicines and properly cooled health facilities and community services,” said the University’s professor Toby Peters.

This project will explore how temperature-controlled food pack-houses could innovate to hybridise and employ technologies to meet other community-based cold needs.

The cooling system could be used to cool a community hall to serve as a crèche for infants or elderly; perhaps providing a schoolroom for classes on the hottest days of the year. Vaccines and medicines could be safely stored at these hubs for local health care services.

The Hubs could host secondary agricultural activities that utilise local resources in terms of labour and farm output, such as processing milk into cheese or yoghurt, making jams and pickles, and Hindu holistic medicines. They would be employment hubs for the local community.

“Community cooling hubs take forward refrigeration from the immediate realm of cooling machines, into the dimension of collaborative technologies and models to drive a weightier wellbeing,” said NCCD CEO Professor Pawanexh Kohli.

The project follows the University of Birmingham’s partnership earlier in the year with the World Bank Group and UK Department of Business Energy & Industrial Strategy (BEIS) to host a global Clean Cooling Congress around sustainable, accessible cooling for all who need it – without over-heating the planet.

Experts at Birmingham plan to work with the NCCD and others, over a period of 12 months with farming communities in the state of Maharashtra. They will be supported by colleagues from Heriot-Watt University, the University of Edinburgh and ImechE.

energy efficiency

Energy Efficiency | Save Energy Save Environment

Energy Efficiency – the subject everyone knows about but most of us don’t know what to do about it. Everybody wants to reduce their energy consumption and pay fewer electricity bills but most of us don’t know how to do it.

Well, today we are going to talk about what can be done to reduce your energy consumption.

Need for Energy Efficiency

So before talking about what to do for energy efficiency, let’s talk about WHY Energy Efficiency?

Energy efficiency means delivering the same (or more) services for less energy. When we use less energy, the less energy we need to generate at power plants, which reduces greenhouse gas emissions and improves the quality of our air. Energy efficiency helps the economy, too, by saving consumers and businesses millions of dollars in energy costs. Energy efficient solutions can reduce the energy bill for many homeowners and businesses by 20 to 30 %.

How to achieve Energy Efficiency – 

There are many different ways to reduce your household’s energy use, ranging from simple behavioural adjustments to extensive home improvements. The two major motives for conserving energy are to save on utility bills and protect the environment.

Here are some ways in which you can save energy & electricity in your house – 

  1. Adjust your day-to-day behaviours

To reduce energy consumption in your home, you do not necessarily need to go out and purchase energy-efficient products. Energy conservation can be as simple as turning off lights or appliances when you do not need them. 

  1. Replace your light bulbs

Traditional incandescent light bulbs consume an excessive amount of electricity and must be replaced more often than their energy efficient alternatives. Halogen incandescent bulbs, compact fluorescent lights (CFLs), and light-emitting diode bulbs (LEDs) use anywhere from 25-80% less electricity and last three to 25 times longer than traditional bulbs.

3. Purchase energy efficient appliances

On average, appliances are responsible for roughly 13% of your total household energy use. When purchasing an appliance, you should pay attention to two numbers: the initial purchase price and the annual operating cost. Although energy efficient appliances usually have higher purchase prices, their operating costs are 9-25% lower than conventional models.

When purchasing an energy efficient appliance, you should look for appliances with the ENERGY STAR label

4. Upgrade your HVAC system

An HVAC system is composed of heating, ventilation, and air conditioning equipment. Heating alone is responsible for more than 40% of home energy use.

Upgrades to the component of an HVAC system – ventilation – can improve your energy efficiency. A ventilation system is composed of a network of ducts, which distributes hot and cold air throughout your home. If these ducts are not properly sealed or insulated, the resulting energy waste can add thousands of rupees to your annual heating and cooling expenses. Proper insulation and maintenance on your ventilation system can reduce your heating and cooling expenses by up to 20%.

5. Insulate your home

Insulation plays a key role in lowering your utility bills through retaining heat during the winter and keeping heat out of your home during the summer. The level of insulation you should install depends on the area of your house. Your attic, walls, floors, basement, and crawlspace are the five main areas where you should consider adding insulation.

Conclusion – Energy conservation is important and beneficial as you can save money, save the environment. Take needful measures today only so that our future can also enjoy something which we are exploiting.

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.

EXCEL COOLCOAT

Understanding the Requirement of Cool roof to keep the Temperature of the Building Moderate & Efficient

How building envelope acts as thermal insulation!

The “building envelope” of the building includes the outside walls, windows, doors, roof, etc. of the home. It is the skin of your house and helps protect everything inside. It offers a physical separation between the environments outside from the one inside the building.

The kind of building envelope you choose will determine how comfortable your home remains at different times of the day, night and during the year. A well-designed building envelope helps in keeping the house as warm, cool, or lit by natural conditions for longer durations, to avoid the use of heaters, air-conditioners or indoor lighting as often.

The thermal envelope of the building is considered as the heat-controlling layer, which is largely the ceiling and the façade of the building. The cool roof coatings offer a wide range of benefits including the lengthening of the roof life, ensuring waterproofing and providing reflectivity.

The heat reflectivity characteristic of the coatings aids in offering UV protection and cooler inside environments, lesser use of air conditioning ultimately lowering the energy utility costs. Moreover, using a heat reflective coating or coating tiles enables cooling at places that cannot be air-conditioned including garages, patios and others.

Which factors enable improved energy efficiency in a building?

Variety of options are considered for enabling improved energy efficiency in building design with improved designs of rooftops. Ceilings of the building can be coated with highly reflective paints, tiled, made as green with plantations, overlapped with panels of materials such as wood, fiberglass, polymer and metals.

Several kinds of research have shown that the external colors of a building have a significant impact on the cooling load of the building. A white reflective cool coat can potentially reduce up to 60% of the heat coming in from the ceiling offering it ultimate protection from thermal heat. However, the results vary in different situations. With various experiments, researchers have found savings to vary from 20% to 60%. Typical rooftop reflective coating paints are made of acrylics, Hypalon, neoprene, silicone, and urethane and hybrid materials.

Cool roof coatings not only prevent extra heat from entering a house but also have many other benefits too including the increase in the lifespan of the roof by 15 years or more. Dense cities with a lot of dwellings in a small area have tendencies of getting heat up significantly. If the houses are acquired with reflective rooftops, then the amount of heat waves can be reduced. In general, it can add to greening by reducing waste and saving electricity.

EXCEL Coat is one such type of sustainable rooftop solution which offers a wide range of products including Coal Coat, NanoSeal, StayCool, CoolTile and InsulX which helps in maintaining the temperature of the interiors of the building. Excel Cool Coat is a heat reflective roof paint to reduce the summer heat on the roofs. It is a reflective paint for exterior walls and first of its kind cool roof technology in India. It is a water-based, high solid, PUD hybrid roof coating that contains both reflection and Nano insulation pigments for best in class heat protection. Along with it, the adhesion enhancer & Nano UV protectors prevent the coating from UV degradation delivering excellent weather ability and longer service life.

This heat reflective cool roof coating is powered with micro-fibers for excellent waterproofing & crack resistance.  It comes with reflection, insulation, and waterproofing. It is the time proven and tested the paint to reduce heat on the roof.

Some of the important points for consideration on excel coatings are stated as under:

1. Normally reflective coating contains only reflective pigments, which work on the basis of reflection. In the current scenario, carbon & fine dust settling is very high, which when settles over the coated surface spoils the reflectivity of the heat reflective roof coating. Thus the coating fails & desired performance is not achieved. To prevent this failure, EXCEL CoolCoat contains high-performance Nano-insulating material to efficiently protect heat from entering inside.

2. Contains high-end Nano UV protectors which protect the coating from aging & degrading within a few years.

3. Contains addition enhancers which provide excellent addition property across a variety of surfaces.

4. Contains reinforced microfibers for excellent water proofing and cracks
