Mission Statement
At DeMaranville Construction it is our goal to work in cooperative balance of both the customer and participants throughout the process of building. By honing the available skills of all those involved in that process. Incorporating the natural artistic and creative integrity of each person involved through out the process. Integrating dialog and planned function with customers. Using durable and available sustainable products and techniques through each phase of the process. Creating overall pleasing and comfortable spaces to live and work in.
Building Science
In our quest to constantly improve ourselves, we are merging 30 years of construction experience with the new technology of home performance. Specializing in:
- Comfort, indoor environment that has an unperceivable draft less temperature delivery.
- Interior air quality, Because we limit airflow from the attics and underfloor in the envalope of the buiding, we install heat exchangers to deliver clean outside air to you home.- Potential of 40% to 80%energy consumption decrease from your heating and cooling demands. We are using smaller heating and cooling units to designed to provide even temperature comfort to the customer resulting in substantial energy savings.
- High level of construction integrity. We are testing all areas of construction performance. We are using materials and techniques that are more immune to application defects that result in a predictable sustainable performance of your home requiring minimal maintenance effort to the customer.
- High level end result customer satisfaction.
We are looking for clients who are interested in learning about sustainable low carbon footprint homes.
Performance tested homes have a greater value of PG&E rebate potential for other possibilities such as photovoltaic solar panels.

There is a lot of guess work in this business and assumptions based on the way things have always been done. Home performance testing is provides clear answers to some real problems in building techniques.
Home performance categories:
Duct testing - Has a potential of 20 to 30% greater performance of the home
Air infiltration - Blower door testing has a 28% potential
Air balancing - Has a 10% potential
Framing - ( % wood in walls) has a 12% potential
Solar gain - (Through windows) has a 30% potential
Insulation - Has a 30% potential 90% if there is no installed insulation and improperly installed insulation performs very close to 0% of it’s capacity.
Air delivery - Velocity, direction, and volume - when properly balanced has a 10% potential.
Evaporative cooler - Has a 13% potential
Refrigerant charge - Correct charge offers 22% potential
Moisture management - Impacts heath, safety, durability and comfort.
Lighting - offers potential 75% savings in this category.
Plug load and Appliances - offers 50% savings in these categories.
There is no one silver bullet in home performance: Home performance research has shown that these items tend not to be cost effective when balancing overall performance of a home.
- Ceiling fans, whole house fans, geothermal heat pumps, PV panels, solar hot water panels, attic exhaust fans, radiant barriers, shading the condensing unit, 2- stage furnaces, zoning, high efficiency equipment.
