Sustainable Green Construction

At D. A. Boldt Construction, your safety and quality of life while living in your home is important to us. What we do and what we use in our daily lives affects our personal wellbeing and our environment. Over twenty years ago I became aware of how the chemical contents of the products we use in our homes adversely affect our health and environment. It has also become increasingly important for all of us to conserve our material and energy resources. Through extensive research and education, I have found many ways to improve your home environment and reduce our impact on the environment.

Construction process
During the construction process we use materials that protect the quality of the home environment as well as reduce our demand on natural resources. Engineered wood lumber for floor joists, sheeting, beams and headers manufactured from wood scraps reduce the demand to harvest trees and provide more stable building components. Engineered wood products are available that don’t contribute to adverse air quality. Plus engineered wood products tend to be stronger and more stable. By using thicker walls and advanced framing techniques and using raised-heel roof trusses we can increase the effectiveness of your home’s insulation.

Other methods of construction that contribute to this process are using ICF (insulated concrete forms), SIPS (structured insulated panels) and exterior wall insulation (thermal break). Windows allow far more heat and cold to pass through than our walls, so we recommend using windows with the highest energy efficiency as possible.

Air infiltration from the outside through walls, windows, doors, floors and ceilings greatly affect the efficiency of our heating and cooling systems. To overcome this we seal all openings through exterior walls, floors and ceilings, including electrical boxes and light fixtures that open into unheated spaces, and we seal all joints between framing members of the shell of the house.

Home environment and air quality
The products in our homes can affect our health and our enjoyment of our home. During the construction process we use products with no added formaldehyde, paints with low or no volatile organic compounds (VOC) and natural materials such as hardwood floors, linoleum and tiles that don’t off-gas. Household cleaning supplies and furnishings are another source of indoor air pollutants so we
recommend you use products that don’t contain harmful ingredients to further maintain the healthy
environment in your home.

The home’s interior environment is greatly affected by the occupants in your home - pets, cooking, furnishings and cleaning supplies. We remove the affect the occupants have on the air in the home by using various exhaust fans. To compensate for the air being removed from the house by the fans we use a heat recovery ventilator (HRV) or energy recovery ventilator (ERV) which removes stale air from the house and brings in fresh air from the outside through the air handler. This insures that air is not pulled in from areas of contaminated air such as the crawl space or wall cavities.

Resources
Our homes are one of the biggest consumers of energy. There are many ways to reduce energy consumption and thereby save money in the process.

The simplest actions to save energy are to turn off lights not in use, use compact fluorescent or LED bulbs instead of incandescent bulbs and lowering our thermostat, especially when the house is not occupied.

Installing high efficiency furnaces and water heaters or using a tankless water heater will further reduce energy consumption. Other high efficiency systems are ground source heat pumps, solar domestic water and space heating systems and photovoltaic s electric systems.

Earth Advantage and Energy Star Northwest programs are guidelines for the construction of an energy and resource efficient home above the current code standard. They provide third party verifiers to certify that the home meets the higher standards.
