Save Energy without Compromising Comfort

Did you know that the performance of other building systems also (to a considerable extent) make demands on an HVAC system?

For example, during sunny days in San Jose, the topmost floor needs more energy to keep cool than the floor below.

It is most likely that a one-story building with a conventional black roof in Texas will cost considerably more to cool when compared to one with a reflective roof. However, if the same structure is in Minnesota and does not have adequate roof insulation, it will cost more to heat in the winter.

But, the roof is not the only part that affects the HVAC loads. Solar heat increase through windows, heat load from lighting systems, and air infiltration also have effects on HVAC loads. This holds true for various equipment as well; the range varies from computers to coffee makers.

In view of the mentioned facts, it makes perfect business sense to reduce energy. While, it costs nothing, it saves money, improves corporate reputation and enables you to do your part in the fight against climate change.

What does reducing energy mean?

A typical human tendency would be to state the following: I like to have my creature comforts such as air conditioning during summer and heating during winter. Reducing energy means compromising on these comforts. No way! I am fine as I am!

Well this is what we have to say.

This is no need to compromise with your comforts and luxuries while reducing energy consumption. All it takes is a little awareness and presence of mind.

We have for you some energy saving opportunities and knickknacks that will help you cut costs, increase profit margins, and save the Earth as well. Heating, ventilation and air conditioning can account for the majority of money spent on energy by a household or an organization. Even small adjustments can significantly improve the environment and also save money.
  • Ensure workspaces and main areas of your home are shielded from draughts and direct sunlight
  • Switch off equipment like mixers, computers, and washing machines or copier machines from the power connection.
  • Dim or switch off lighting if you have sufficient daylight filtering into the area
  • Ensure all controls are well-set. Time controls need to be monitored regularly
  • Motivate family members and staff, encouraging them to review their practices and suggest ways to increase awareness towards energy consumption.
  • Awareness on the potential waste in workplaces is important for reducing energy consumption.
Depending on the area required for cooling, the size and functions of heating, ventilation and air conditioning systems vary. Some are large and some small. It would be good to analyze if the functions of these systems could be separated. For this, interaction of their services with each other needs to be scrutinized. For example, it is a sheer waste to increase the heating inside a building while the cooling device is trying to reduce the temperatures. A thorough look at how the elements of an HVAC system interact and fine tuning each part can save energy and money.

How to Reduce Energy Needs

We all love to have our creature comforts when we need them. The air conditioning during summer and the heater during winter! We rarely ever give a thought to the energy we use in using these systems. Nor do we spare one for the carbon footprint created due to the use of these systems. 

The world is now becoming more and more aware of the carbon emissions that cause carbon footprint, whose one of the results is global warming. There is a definite need to look for alternate forms of energy as the world’s energy reserves are being eaten up at an alarming pace.

“Experts at the Risø International Energy Conference in Denmark advocate using "off-the-shelf" technologies to create a sustainable global energy system. As long as the solutions can respond to fluctuations in energy consumption, intelligent energy systems are within reach. The most accessible improvements may be heating and cooling systems, suggests the International Energy Agency (IEA).”

Where do we stand? What is it that we can do to reduce our contribution of the carbon footprint?

We need to serious give a thought to the amount of energy we consume.
  • The age of the appliances we use at home, especially or HVAC systems
  • The direction our house or apartment is in
  • The technology available in our HVAC systems
  • The "off-the-shelf" technologies that can create a sustainable global energy system
  • A serious effort to reduce energy consumption
These points need not lead to you compromising on your comforts. You can actually reduce your energy consumption without depriving yourself and your families of the comforts you and they are used to.

All it takes is a little awareness, a sincere effort, and little discipline!

These tips can help you to reduce your energy consumption to a great extent.
  1. Passive heating, ventilation and cooling: This refers to controlling of heat from the sun along with ventilation to create benefit and avoid discomfort.
  2. Maximizing inflow of natural, fresh air into the house will reduce energy spent on artificial airflow techniques.
  3. Using ‘artificial’ and mechanical systems to fine tune the air indoors to the desired temperature, rather than creating the airflow.
  4. Ensuring cross ventilation: this means having openings such as large windows preferably on opposite sides of the room. This will enable air to flow in and out easily.
  5. Making the most out of the natural ventilation and light. This means you should try and use as much as natural sunlight to light up the room during the day, rather than using artificial lights.
  6. Installing daylight blinds to enable natural light to enter the space is a good way to reduce energy consumption.
  7. Using perforated blinds to use view the outside world.
  8. Using solar heater to heat water for domestic use
  9. These tips will not only help in reducing energy consumption, but also keep your pockets happy and you smiling!
