ANACORTES HOSTS ENERGY CONSERVATION WORKSHOP

Staying Warm in Your Old House: An Energy Conservation Workshop Saturday, Feb 27, 10:30 am Anacortes Public Library Meeting Room An Energy Conservation Workshop, sponsored by the Anacortes Historic Preservation Board, the Anacortes Museum, and the Anacortes Public Library, will help homeowners improve the efficiency of their old homes, while preserving key architectural features. Topics covered will include:
- Windows. If your house was built before 1940, the window frames (and probably the entire house) were made of the highest quality old-growth timber, nearly impossible to buy today. If maintained, those windows can last almost indefinitely. Rather than replace vintage windows, simply add a storm window. You’ll get the same insulating benefit for far less cost and with fewer wasted resources.
- Air Leaks. Eliminating air filtration is an easy, inexpensive, do-it-yourself project. The most frequent culprits are gaps around pipes, ducts, and electrical chases that pass through the floor into an unheated space, through the ceiling into the attic, and through exterior walls. Seal these gaps with caulk or aerosol foam insulation and caulk all the baseboards. And don’t forget to use insulating kits around electrical receptacles and switches located on outside walls.
- Insulation. Most heat loss is through under-insulated attics and floors. Adding adequate insulation improves R values more than switching to the most energy efficient window. The homeowner who adds both attic and floor insulation (R38 and R30 respectively, which is required by the Washington State Energy Code for new construction) can expect to cut their heating bill by two thirds—an excellent return on investment.
- Large amounts of energy are required to produce, transport, and erect the materials used in new construction. Conversely, significant energy and resource savings are realized when an old building is preserved. By reusing the old structure, the original energy and resource investment is maximized; demolition and reconstruction costs are avoided, and nothing is added to the nation’s enormous waste stream.
- Pre-1940 buildings were often built for the long term. They used local materials—brick, plaster, concrete, wood—thus minimizing transportation costs. And they were designed to take advantage of natural lighting, cross-ventilation, and solar/thermal properties.
- Newer structures often use materials that require more resources to produce and transport. These include such energy hogs as plastic, steel, vinyl, and aluminum. New construction often relies heavily on mechanical systems rather than natural forces for climate control and lighting.
