To be energy efficient, a building must be effectively insulated. Consider these tips.
Low cost options
Check all windows and doors for draughts, and seal up the draughts with weather stripping. Block unused openings in the walls or roof.
Install automatic closers on doors that let in cold outside air (e.g. main entrance, reception, car park and delivery areas). This will help reduce heating and air conditioning costs.
Install shades and awnings to prevent overheating and sun glare.
Options to invest in
Install insulation in your roof to reduce heating and cooling requirements. Refurbishment When refurbishing look for ways to save energy. For example a “draught lobby” acts as a barrier between reception areas and the outside.
