Dear Customer,
This is our approach to bringing more value to your energy compliance reports.

Doing load calculations and duct design is required by the energy code, Title 24, part 6 and CalGreen Title 24 part 11. Many building departments don't know this, but they do know they need a CF1R energy report. You are familiar with the energy report that you get from energy consultants before you can get a permit to add on, etc.

The same data-set is used for both so we do the work in Wrightsoft which does load calcs and duct (manual J, D and S) design and assists with equipment selection. We then export that dataset into EnergyPro and, after a few modifications, we generate the CF1R PRF-1. We feel that we can offer our clients a two-fer this way and get them more value for their energy compliance budget.

We started doing Wrightsoft after years of watching air conditioner installations fail (over 80%+!) because HVAC contractors don't do the math and don't know how to build energy models like in Wrightsoft. This was an attempt to follow the code and design systems that work properly and pass code mandated HERS tests.

We also use the kind of duct designs one can learn at PG&E's Pacific Energy Center in the class, "Optimizing Residential Duct Systems". Keeping the ducts inside the conditioned shell and optimizing airflow makes for better operating systems that provide more comfort at lower cost. We also design our systems to be able to run properly with restrictive MERV 13 filters which filter out pollen, pet dander, wood smoke and PM2.5 particles for our clients with respiratory concerns.

We think that pulling it all together for our clients creates better housing that is healthier, more comfortable, durable and less costly to operate. We hope you agree.
