Long before the term "building green" entered our vocabulary, we at Ann Arbor Builders believed that harmony could and should exist between home and the environment. That's why for many years we've been committed to doing our part to reduce the impact that building has on both people and nature...and it's why we build homes and buildings that are healthier for their occupants and healthier for the environment. Simply stated, we incorporate sustainable building practices into every home we build, and we've been doing it for years.

Our commitment to sustainability means that we build homes that reduce energy usage and thus reduce carbon emissions into the environment. We do this by using renewable and sustainable building materials and energy efficient features. You benefit by saving energy and energy costs...and at the same time, you're helping to save the earth.
We at Ann Arbor Builders believe that we have the responsibility to do our part to leave more for future generations to enjoy. That's why we believe that sustainable building and design is not only the right choice. It's the only choice.

estimated to deliver up to a 30% improvement of energy efficiency
over typical new homes and even more over most existing homes.
All our homes include:
- 95+ High Efficiency Furnace
- 13 SEER Air Conditioning
- Programmable Thermostat
- High Efficiency Hot Water Heater
- Double Pane, Energy Star Rated Windows With Low E and Argon
- Tyvek Housewrap
- Energy Heel Trusses
- Complete Interior Caulk Package
ENERGY HEEL TRUSSES: As shown in the diagram below, conventional truss design prevents insulation from fully extending to the edge of the wall. Not only is a cold spot created, but a great deal of hot or cold air escapes in this area.
By adding a “heel” to the truss, full-depth, uncompressed insulation reaches all the way to the outside wall, thus eliminating the cold spot that is unavoidable with conventional truss design. This also lessens the amount of energy needed to heat or cool the living space and optimizes the efficiency of the HVAC system.
Raised heel trusses are also called energy heel trusses because they contribute to the energy efficiency of the house. Ann Arbor Builders uses energy heel trusses in every home we build.
TYVEK HOUSEWRAP: Sheathing on the exterior walls consists of oriented strand board (OSB) which is covered with Tyvek Housewrap. Your walls will later be insulated, but insulation is not designed to block the heat loss attributed to air infiltration. Tyvek is an air infiltration barrier which reduces drafts and outside air that can penetrate your home through cracks and seals. It enhances your insulation's performance and results in greater energy efficiency. Without a protective barrier to combat air infiltration, your energy bills would increase.
Tyvek also resists water penetration, but it allows smaller moisture vapor particles to escape. This feature reduces the chance of condensation within the cavity of your walls which could be harmful to both your walls and the insulation within them.
CELLULOSE INSULATION: In the exterior walls, we typically use wet spray cellulose which is made of approximately 80% recycled newspapers and is denser and more resistant to air flow than fiberglass. Because cellulose insulation is sprayed in place, it reaches behind electrical boxes and penetrates into crevices where batt insulation cannot reach, as shown in the picture to the right. Thus cellulose provides better energy efficiency for the exterior walls.
Since most heat escapes through the attic, higher R-value insulation is necessary. There, we typically use blown in cellulose to achieve a minimum R-42 value.
INTERIOR CAULK PACKAGE: Air leakage, or infiltration, occurs when outside air enters a house through cracks and openings where wood meets wood. Properly sealing them reduces energy costs. That’s why we include a complete caulk package of all exterior walls, which consists of sealing any areas where outside air may penetrate.
