The Derry Energy & Environmental Advisory Committee will be sponsoring a free seminar on how to save energy in the home at the Derry Public Library on Saturday, May 18th from 2:00 to 4:00. Participants will learn about simple and inexpensive home improvement projects that will save energy, save money and make you more comfortable year-round.
This seminar will be presented by Tom Minnon, who has over 35 years of experience in energy conservation and renewable energy. “Most homeowners can do several inexpensive things to save energy and money on their heating and hot water bills” says Minnon. “Up to 30% of a home’s heat loss is due to air infiltration. We’ll show homeowners how to identify those areas where infiltration is occurring and how to seal them”.
Windows are a major source of heat gain in the summer and heat loss in the winter. Even the most energy efficient windows only have an insulating value equal to about 1” of fiberglass insulation. Applying energy saving films, adding the proper storm windows, weatherstripping and using the right drapes and blinds can have a significant impact on energy use and human comfort. This seminar will show homeowners how to improve their existing windows and what to look for in buying new windows.
Most homes’ attic insulation is way below recommended levels. Here in Southern NH, attic insulation should have an R-Value of 50 or more. That’s equivalent to about 16” of fiberglass insulation. If your home has less than that, this seminar will show you how to efficiently and effectively bring it up to standard. Minnon adds, “Just as important to adding insulation in the attic is making sure that the attic has proper ventilation. Improper or ineffective ventilation can result in mold growth in the attic and ice dams during winter”
A major source of energy use in the home is heating hot water. Adding insulation to an electric water heater, insulating hot water pipes and installing a timer can reduce the cost of heating hot water. Minnon will also show participants how to make a simple solar hot water heater that is very effective during the warmer months, resulting in savings of up to 50%.
The Derry Library is located at 64 E. Broadway. Prior registration is not required.
