New does not equal energy efficient
With the increasingly tight construction methods, materials and requirements of new homes, energy modeling has become increasingly important.
Used to accurately size, select and locate HVAC equipment in new homes, energy modeling is becoming more and more essential.
Energy modeling can be a helpful tool in the design phase as well as prior to, and into construction.

Replacing the boiler or adding AC to your existing home?
Energy models for existing homes can be a useful tool when it comes to replacing outdated HVAC equipment.
Chances are the HVAC equipment in your home was sized using a ball park guesstimate. Likely leaving you with oversized equipment or even undersized distribution. Improperly sized HVAC equipment often leads to short cycling, increased wear and tare, increased operating costs and reduced operating life for your equipment.

Manual J calculations are required by more organizations and programs every day, including:
- Certifications, like Passive House, HERS, DOE
- Electric Utilities, to qualify for rebate programs
- Building designers, for decision-making in the design phase
Already an essential design tool, energy models are used for code compliance, utility incentives & green building certifications. As we move towards a resilient, sustainable & emission free future, energy modeling should be used as a tool for decision making. Not only for sizing equipment but also for shaping buildings & selecting materials as well.
As part of the Inflation Reduction Act, the Section 45L Tax Credit for Energy Efficient New Homes now provides a $5,000 tax credit for those who build a home participating in the DOE Zero Energy Ready Home (ZERH)Program.
