A whole-house system approach to building or renovating an existing home is the most effective method to optimizing home energy efficiency.

How It Works
The whole-house system approach looks at a home as one complete, integrated unit of interdependent parts all working together in tandem. The result is a highly energy efficient home that generates lower utility and maintenance costs, while providing a more comfortable home environment.
Designing a house using the whole-house system approach consists of performing a number of computer simulations that put together different combinations of variables, and then compare results to come up with the most cost-effective and energy efficient solution.Variables could include:
- Site conditions
- Local climate
- Appliances and home electronics
- Insulation and air sealing
- Lighting and day lighting
- Space heating and cooling
- Water heating
- Windows, doors, and skylights
Why Use the Whole-House System Approach
There are number of tangible benefits to building or renovating a home using the whole-house systems approach, including:
- Reduced utility and maintenance costs
- Increased comfort
- Reduced noise
- A healthier and safer indoor environment
- Improved building durability
