Example Energy Rating Report

We typically achieve energy ratings below 50, which means that the home requires less than half the energy of a typical new home constructed today, and less than 40% of the energy of all existing homes.
The Ultra-Energy Efficient Home
Designing and building a new home or renovating an existing house to be highly energy-efficient requires careful planning and attention to detail.  We take a whole-house systems approach to develop a successful strategy for optimal home energy efficiency.
This approach considers the house as an energy system with interdependent parts, each of which affects the performance of the entire system.

To ensure that your new or renovated home takes full advantage of optimal efficiency, we use a computer model that takes into account the layout of the house, the heating systems, lighting, and ventilation system to determine an expected energy consumption model.  At certain stages of the construction process the structure, insulation, ventilation, and air seal of the house are tested to validate the model.

Some of the primary model variables include:
  • Site conditions and local climate
  • House structure and site location
  • Appliances and home electronics
  • Insulation and air sealing
  • Lighting and daylighting
  • Space heating and cooling
  • Water heating
  • Windows, doors, and skylights
  • Advanced framing materials
  • Heat recovery ventilation systems
  • Passive energy systems such as solar or geothermal

The benefits of using a whole-house systems approach include:
  • Reduced utility and maintenance costs
  • Increased comfort
  • Reduced noise
  • A healthier and safer indoor environment
  • Improved building durability

The most important factors are those that minimize energy load requirements and then by adding renewable energy systems that generate electricity and heat water you can achieve an energy consumption model that is a small fraction of your typical home.
