1. INITIAL RATING
VISUAL INSPECTION & MEASUREMENT
In the Initial Rating, we measure the building envelope, framing and
insulation values, window type, area, u -values, and solar heat gain
coefficient, the energy demands of lighting and appliances, and scores
of other home energy factors.
We quantify the amount of air conditioning system leakage and whole-
house air leakage to determine the amount and causes of energy waste.
We email you a report of our findings, in two parts.
(1) Analysis of your home in terms of ...
Heating and cooling requirements ("loads"), compared to the nominal quantity
Annual energy consumption for heating, cooling, water heating, and operating lights
HERS Score for your home, as it is now
(2) Recommended Improvements that can be done to increase energy efficiency,
including each improvement's ..
Impact on reducing heating and cooling loads
Projected savings on annual utility bills
Approximate cost, so you can understand cost/benefits
Impact on your home's HERS Score
And detailed, specfic steps to make the improvements
2. MEETING WITH HOMEOWNER
This is an approximately 1 hour meeting with you to ...
Impart the basic science of heat transfer, so that you can completely
understand the rating analysis and recommendations
Discuss the recommendations, viewing photos of locations in your attic and house
where improvements can be made
Look at products, installation methods, and ball-park costs of simple improvements
3. FINAL RATING
An assessment of the quality of work and effectiveness of improvements
Re-measurement of the air conditioning/heating system to quantify leakage and see if further sealing is necessary (Duct Blaster Test).
Re-measurement of whole-house air infiltration to quantify effectiveness of air sealing work (Blower Door Test).
You receive a final report on the imporved values for heat/air conditioning system leakage, whole-house air leakage, and other features measured.
You also receive a certificate showing your home's final HERS Score.
