Energy Efficiency

IMPROVING THE ENERGY EFFICIENCY OF OUR BUILDINGS

The Department for Communities and Local Government has issued guidance “intended to help anyone who manages or controls an air conditioning system to understand how the Energy Performance of Buildings Regulations (Certificates and Inspections (England and Wales) Regulations and the Directive, on which these regulations are based, work in practice, how to apply the regulations, what their responsibilities are and when air conditioning inspections are required.”

Air Conditioning

THE SUMMER MONTHS ARE UPON US. HAVE YOU REVIEWED THE EFFICIENCY OF YOUR VENTILATION AND AIR CONDITIONING LATELY?

The Carbon Trust have issued a very good guide for energy efficiency, heating, ventilation and air conditioning.

Ventilation

Good ventilation is essential – it gives you fresh air and also helps protect a building against damp and condensation. Unnecessary ventilation at the wrong time of year can waste energy and cost you a lot of money.

For example, ventilation accounts for around 30% of heat loss in most commercial buildings (an estimated 25% in industrial buildings).

  1. Motors: As mentioned by the Carbon Trust, “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”.
  2. Timer settings: Make sure fans, electric heaters and gas boilers are not running when they are not required. This wastes energy and removes heat from the building.
  3. Thermostats: Ensure that thermostats close to open windows are set correctly.

Air conditioning

Air conditioning can use a huge amount of energy. Air conditioning can increase a building’s energy consumption and associated carbon emissions by up to 100%, according to the Carbon Trust.

There are some simple, low-cost ways to save energy and make your air conditioning system more efficient.

  1. Temperature control: Make sure your air conditioning doesn’t operate below 24°C. Also, make sure that the heating and cooling systems are not 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.
  2. Variable speed drives: 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 provided the temperature control is set correctly.
  3. Timer settings: Make sure the timer settings on your air conditioning are set correctly. This is so the minimum amount of air conditioning is being used outside the operating hours of your premises.
