Heating, ventilation and air conditioning (HVAC) is the current technology of indoor environmental comfort. Main aim of it is to provide thermal comfort and improve indoor air quality.
Heating and hot water can account for 30-40% of total energy use. By ensuring that efficient heating systems are specified, operated and maintained the potential savings can be substantial. There are three key ways of cutting your heating costs:
- By turning temp. down – By setting lower point by just 1°C we can potentially reduce your annual heating bill by up to 8%, so reduce the temperature on the thermostat down to the minimum comfortable level.
- Installation of de-stratification fans – In commercial or industrial buildings with warm air heaters and high ceilings, de-stratification fans can reduce energy use by 20% by blowing warm air down to ground level where it’s needed.
Good ventilation is essential at all places. It gives us fresh air and also helps protect a building against damp and condensation. Unnecessary ventilation can waste energy and cost you a lot of money.
- Motors – When buying new motors, always specify higher efficiency motors as they will save you up to 5% on energy costs, for little or no extra capital cost.
- Fans – Variable speed fans can slow down when ventilation demands decrease. This will save money on electricity as well as reducing heating/cooling costs.
- Time settings – If fan is running even also when they’re not required in this they not only wasting energy, but also removes heat from the building.
Air conditioning also uses a huge amount of energy. In other words, air conditioning can increase a building’s energy consumption and associated carbon emissions by up to 100%.
Even though air conditioning can use lots of energy, lots of organization’s choose to use it just because of the limitations of extra heat generated by IT equipment’s .
There are some simple, low-cost ways to save energy and make your air conditioning system more efficient.
- Temperature control – Make sure your air conditioning doesn’t operate below 24°C. Also, make sure that you don’t have the heating and cooling systems competing with each other – it’s a waste of money. The best way to do this is to keep a temperature gap between your heating and air conditioning control temperatures.
- Variable speed drives – Producing more cooling than need is also non efficient affair. This simply wastes money and energy. Variable speed drives can vary the output of your air conditioning system to meet your needs throughout the day. This will help you save money on energy costs.
