Energy models confirm savings
Daylighting systems particularly well suited
HVAC may qualify with as little as a 25%
improvement over standard

Currently required for all HVAC and building envelope
deductions and for whole building lighting alternative.
In many jurisdictions, rebates are provided for all or
substantial portions of modeling costs.

Model and size your actual building and HVAC system
Model a reference building designed to ASHRAE 90.1
2001 data using Title 24 loads and ASHRAE 90.1 2004
Appendix G methodology.
Copy the reference building and remove the reference
HVAC equipment. Insert the actual equipment from step 1
into this reference building. Compare the cost of energy
between step 3 and step 2. A 16.67% improvement gets
tax savings.

The Modeler’s role

Analyze existing projects for EPAct potential
–

Most projects are on the margins(between 0&1 or 1&2 deductions)
–



23
Communicate the potential to Management
Suggest design improvements to capture additional EPAct $’s
Modeling is now a profit center for government projects
More & more rebates are based on modeled results
Additional EPAct $’s corresponds with added LEED pts.
