Energy Efficiency Auditing questions, answered by experts

Fireplaces can theoretically help you save on heating bills if you lower the temperature throughout the rest of your home and heat only a single room that you occupy using the fireplace. However, in most cases, homeowners won’t save any money on heating bills. Gas and electric fireplace inserts could actually lead to a spike in your respective energy bills if you use them frequently, and if you don’t keep up with chimney maintenance and repairs, your traditional masonry fireplace could actually be a source of heat loss in the winter.

Modern windows provide enhanced UV protection, improved heat retention, and cooling efficiency, contributing to overall household energy savings.

Blower door tests are measured in a few different ways, but the most popular are air changes per hour (ACH) and cubic feet of air (CFM) moving through the house per hour. A good ACH score is less than 2ACH, but 1ACH is better. This means the house experiences a total air change within 60 minutes (for 1ACH). For 2ACH, there’s a complete change every 30 minutes, and so on. CFM scores are similar in that a lower score means less air change, and therefore less leakage.

Window AC units use a fair amount of electricity during use, but the usage pales in comparison to central units. As a matter of fact, window units use around a third of the amount of energy as a central AC. On average, a window air conditioner costs between $15 and $40 per month to run, though this depends on a number of external factors.

While many states require all new construction to undergo blower door tests, it’s not a requirement for existing homes. But in both cases, a blower test helps confirm that the contractor has sealed the exterior, that the type of ductwork installed is functioning properly, and that your home is as efficient as possible.
