Energy Efficiency Auditing questions, answered by experts

Yes, skylights can affect a home’s energy efficiency, either positively or negatively. Properly installed, energy-efficient skylights with Low-E coatings, double glazing, and UV-blocking glass can help regulate indoor temperatures and reduce heating and cooling costs. However, poorly insulated or older skylights can contribute to heat loss in winter and excess heat gain in summer, lowering overall energy efficiency.

The effect a gas fireplace has on your gas bill will depend on how often you use it, the size of the rooms you’re heating with it, and the BTUs of the fireplace itself, but generally speaking, it should only cost a few cents an hour to run it when it’s on. It will consume minimal energy when it’s “off” if you have a pilot light running constantly, but some modern gas fireplaces don’t require a constant pilot light.

A whole-home humidifier can impact your energy bill positively. In colder months, humidified air feels warmer, allowing you to lower your thermostat without sacrificing comfort. This can lead to energy savings as your heating system works more efficiently. However, it's crucial to use the humidifier judiciously to avoid excessive humidity, which might strain your cooling system in warmer months.

Audits include inspecting insulation, HVAC systems, windows, and appliances to identify energy inefficiencies.

Upgrade to double-glazed glass or apply energy-efficient coatings to reduce heat loss and utility costs.
