Goals of Innovation:
To renovate and expand a historic (1918) home into an executive style residence while developing a mainstream traditional design to appeal to the norms of the real estate market.
To incorporate green principles throughout the project and produce a resource efficient home.
To target reuse and recycling of existing resources.
Description: The processes and methods of demolition and reuse were as important as the installation of new green products. A key was developing knowledge of the local organizations and individuals that take demolition materials from the jobsite. Approximately one dozen 30 cubic yard dumpsters full of trash were diverted from the landfill as a result of the extensive recycling measures taken on this project. Recycling of products for use on other projects helps to reduce the amount of natural resources required to produce new products as well as eliminating additional material sent to landfill.
The builder reused large amounts of construction waste on-site such as brick ground and used as gravel, wood scrap that was turned to mulch, and drywall ground up for soil amendment. Cabinets, counters, fixtures, doors, lumber and other products were either donated to non-profit agencies or used off site in other renovation projects. Donations were eligible for tax deductions. The original concrete driveway was removed and hauled to a recycling plant where it was ground into aggregate rather than being dumped. The same plant provided gravel used for underlayment below the replacement driveway.
The Seville Residence also used new materials efficiently by designed the framing with optimum value engineering techniques. These techniques reduce the amount of lumber used while still maintaining the structural integrity. Headers were sized and placed specifically for each location, and ladders, T-walls, and open corners were used to increase areas for insulation.
New energy efficiency features including spray foam insulation, windows, advanced sealing techniques, and tankless water heaters all add to the green success of the home.
Obstacles: Since the home is in a historic district, all improvements to the exterior of the home were approved by the historic commission. A dormer on the front and other design changes were approved without objection.
Cost Information: The cost of the renovation was right in line with similar renovation projects in the area. But, this renovation will lower utility bills, allow the homeowner to expand while staying right in the old neighborhood, and improve the quality of the indoor air resulting in protection for the whole family.
