How Energy Auditors Make Homes More Efficient

Areas of Heat Loss in Homes EFFICACY OF ENERGY AUDITS Flue Loss Roof Loss 30%-35% Loss through Walls 25%-30% Ventilation Loss 25% The inspection and analysis of the energy flows for the purpose of conserving energy in a building is called tenergy audit". This process of reducing the amount of energy input is crucial for having a sustainable future.

Set targets based on energy efficiency Blower Door is also known as Air Pressurization Test. Between the inside and outside of your home, it creates a small amount of pressure difference. This helps air to get out of the building through the gaps. You can check the amount of air leakage through windows, vents, chimneys and other places. Get increased profits with reduced costs Leaking heat Avail comfort and improved productivity with secured energy supply.
