Garden windows bring more light into the room than a flat window, and if you choose one that will open, it can provide more fresh air as well. Even if it's a small window the extra light and source of air can be refreshing. You can create more shelf space in the window area for the room with a garden window.

Energy Efficiency Auditing questions, answered by experts

STC (Sound Transmission Class) is a rating that describes how well a building material or assembly blocks airborne sound. A higher STC rating means less noise will pass through the material, providing better sound reduction. This rating system applies to various building components, including windows, doors, flooring, drywall, and insulation.

For context, a typical single-pane window has an STC rating of around 25 (where normal conversations are audible), while a well-sealed, double-pane window can exceed STC 45 (blocking loud speech and most music). It is important to note that for some products, like soundproofing drywall, the STC rating refers to the entire wall system, not just the individual panel.

Additionally, STC ratings are most effective for measuring sound reduction at mid-to-high frequencies, such as human speech, and may not accurately reflect how well a material blocks low-frequency sounds like bass music or thunder. Because of these factors, it is recommended to consult a professional to determine the right STC-rated materials for your specific soundproofing needs.

A whole-house humidifier can positively impact energy consumption by improving heating efficiency. During colder months, humidified air feels warmer, which allows you to lower your thermostat without sacrificing comfort. This adjustment can lead to significant energy savings as your heating system works more efficiently. However, it's important to use the humidifier judiciously, as excessive humidity could potentially strain your cooling system in warmer months.

Energy-efficient windows are judged on their performance according to a few different factors, including heat transfer, air leakage, light transference, and condensation resistance. If you're unsure whether a window is energy-efficient, look for an ENERGY STAR® label from the U.S. Environmental Protection Agency (EPA). If various products, including windows, meet energy-efficiency standards set by the federal government, the EPA issues this label to help consumers identify energy-efficient products.

Not all homes are suited for solar panel systems. Older roofs or those in poor condition may need repairs or replacement before solar panels can be installed. Some other factors to consider are the amount of sunlight your roof receives, the roof’s orientation and pitch, and any shading from nearby trees or buildings.

After you receive your audit and report, review the findings and determine which of the prescribed changes you want to make to improve your home’s energy efficiency. Start by contacting the type of professionals recommended by the auditor who can help you remedy the issues discovered during the audit. Prioritize the projects by urgency, importance, and budget. Then, gather estimates from several professionals, remembering to verify any necessary licensing and experience information.
