If you thought getting Manual J reports and correct sizing have been difficult in ENERGY STAR Version 2, just wait till Version 3 kicks in. HVAC contractors have to report subcooling/superheat values, static pressures, and more, and insulation contractors have to do Grade I installation.
Version 3 is definitely harder, but I think it gives us a chance to force all the stakeholders to work together as a team
. A lot of homes have qualified for ENERGY STAR without key stakeholders really buying into the program, but I don't think that will be able to happen with Version 3.
To learn more about this, you can download a 16 page white paper that I wrote on the changes coming with Version 3. Some of the topics I covered in it are:
- What's New in Version 3?
- Version 2.5 - The Transition to Version 3
- Calculating the HERS Index Target
- The Hardest Parts
- Advice for Stakeholders (raters, providers, builders, & trade contractors)
ENERGY STAR just yesterday announced that the start of Version 2.5 has been delayed by 3 months, but there's still a lot to do to bring all the stakeholders up to speed. http://bit.ly/hGyP1X
