What is Energy Efficiency?


One of the most important steps toward sustainability and energy independence is making the most efficient use of every watt and BTU generated. Building performance and building science include a variety of disciplines aimed at maximizing the energy efficiency of residential and commercial structures. Some of these disciplines are building design and site planning, energy use auditing, weatherization and renewable energy systems design and installation. Residential energy efficiency retrofits, through programs like Energy Star, take a whole-building approach. The development of net-zero buildings, which produce as much energy as they consume, is a growing aspect of building science.

Benefits of energy efficiency include

  • Reduce energy waste
  • Lower utility bills
  • Most effective way to directly reduce use of fossil fuel for energy production
  • Greatly increases the effectiveness and impact of renewable energy sources

Energy Audit
A home energy audit is the first step to assess how much energy your home consumes and to evaluate what measures you can take to make your home more energy efficient. An audit will show you problems that may, when corrected, save you significant amounts of money over time. During the audit, you can pinpoint where your house is losing energy. Audits also determine the efficiency of your home’s heating and cooling systems. An audit may also show you ways to conserve hot water and electricity. You can perform a simple energy audit yourself, or have a professional energy auditor carry out a more thorough audit.
