HOME PERFORMANCE ASSESSMENTS
Home Performance Assessment Facts:
Most houses leak 25-40% of conditioned air, much of it to outside
About 1/3 of houses have combustion safety issues
Our homes are making us sick due to trapped contaminants
These problems are made worse by adding bigger air conditioners
8-25% of electricity is wasted by appliances with motors
Purpose: improve energy efficiency, IAQ, and moisture control
Goal: healthy, safe, durable, comfortable, & energy efficient home
Reasons to Inspect:
High gas and electric bills
Presence of mold, including mildew
Uncomfortable rooms
Difficulty breathing
Excessive dust
High humidity
Flu-like symptoms in the middle of summer
Unexplained headaches, itchiness, sinus trouble, burning eyes
Benefits:
Buyers: Understand building performance issues before purchase
Owners: Improve health and correct building performance issues
Sellers: ENERGY STAR certificate makes it easier to sell house
Inspection Focus:
The goals of a Home Performance Assessment are as follows:
1. Identify issues with combustion appliances, particularly drafting and carbon monoxide production
2. Identify conditions affecting indoor air quality, such as moisture intrusion
3. Check for high water use plumbing fixtures, such as toilets and showerheads
4. Identify air leakage sites, where unconditioned air is introduced in the building
5. Quantify air infiltration into the building in terms of average annual natural air changes per hour
6. Quantify air leakage from the air distribution system
A complete visual inspection of all the components of a home and their operation is the scope of a home inspection. This assessment considers how all the components of the building work together and their effects on health and safety, building durability, comfort, and energy efficiency--work outside the scope of a standard home inspection. This assessment may identify issues covered by a home inspection and are offered as spin-off benefit. Ideally, a complete home inspection should be performed first.
