We are all looking for the competitive advantage right now and I believe that “Energy Efficiency is fast becoming the defining issue of our times” With all of the “green” talk around our industry that we must seek innovative, sustainable solutions that promote efficiency first.

So here is a quick reference to help you understand what that means and how you can help educate your clients. 

The key to design and construction of new homes

Systems Thinking: The house as a system concept. This concept has come online for the design and building of new residential homes.  All three components must operate in harmony within the environment they are placed.  If one changes it effects the other.

The components of the system:
o The structure -  Thermal Envelope
o The equipment and the systems - Systems of comfort and security
o The occupants - Lifestyle, operation, maintenance

By integrating this thinking into our new home design and construction we can eliminate comfort and health issues, increase energy efficiency and increase durabilty/longevity as well as overall sustainability of the homes that we design/build/sell/buy and live in.

The key to performance upgrades in existing homes

An Energy Audit is a study that provides insight into existing home conditions such as: Air leakage, Insulation values, mechanical systems.  There are three key tasks associated with  completing an energy audit: 

o Clipboard analysis of the entire exterior ‘shell” the mechanical systems and targeting comfort issue areas or health concerns.
o Blower door test:  Apply a large fan to the front door of the home and depressurize the house.  This allows the air infiltration to be applified and hence targeted for repair/awareness.
o Infrared camera:  In conjunction with the blower door the Infra red camera measures temperatures and can pin piont places where cold/warm air is infiltrating the house.

From these three items a very in-depth report is developed for the homeowner/contractor/agent/seller/buyer can look at areas for upgrades in not only energy use/waste but also to increase comfort and overall awareness of their house as a system.  Utilizing the audit report the homeowner is equipped with solutions to increase their home performance.  Hence developing strategies and listing the priorities of performance upgrade work to save money and energy.  These priorities will help everyone invloved make educated decsions on their homes efficiency.
