Energy Efficiency Auditing FAQs, answered by experts

Motion-sensor lights use one watt while on standby and five watts while turned on. They’re usually on for one hour over a 24-hour period, bringing the total wattage to about 28 watts per day. LED lights use around 6.5 to 8 watts while on. If you leave an LED light on all night, with night ranging from 10 to 14 hours, you’re looking at using 65 to 112 watts a night. You can minimally cut your wattage in half by switching to a motion-sensor light.

Attic and whole-house fans improve a home's energy efficiency and comfort. They ventilate hot air from the attic, which reduces peak cooling loads, lowers reliance on air conditioning, and decreases indoor temperatures. This improved air circulation and expedited heat exit helps lower cooling costs, balance moisture levels, and enhance overall natural airflow, contributing to the efficient operation of other home equipment.

Yes, energy-efficient windows really can make a difference. As long as energy-efficient windows are properly installed and maintained, they can reduce your energy bill and offer significant savings.

A good SEER rating for an HVAC system is typically between 15 and 20. However, minimum requirements vary by location; HVAC systems in northern states must have at least a 14 SEER rating, while those in southern states need a minimum of 15. For the highest possible efficiency, look for units with a SEER rating of 21 or higher. It's important to remember that a SEER rating represents the maximum efficiency a unit can achieve, not the level at which it will operate at all times.

The three levels of home energy audits include:

  • Level 1: Review of your energy bills and home for signs of energy inefficiency and areas for improvement. The average cost range is $0.08 to $0.12 per square foot.

  • Level 2: A level 2 ASHRAE energy audit costs $0.12 and $0.35 per square foot. In-depth analysis of your energy usage and provides a report of cost-saving changes.

  • Level 3: Comprehensive analysis and detailed recommendations for ways to improve your home’s energy efficiency. A level 3 audit costs about $0.36 to $0.50 per square foot.
