Starting in EnergyPro 10.0 you will find two LSC (Longterm System Cost) scores and a Source (emissions) score when doing a compliance calculation. An LSCe score which represents the efficiency of the building design and includes all end uses with the exception of PV and Battery. An LSCt score which is the building efficiency score including the savings contribution of PV and Batteries, and a Source score, an emissions score that is similar to the LSCt score and includes all end uses and factors in the Green House Gas emissions that result from the gas and electricity that is consumed to run the building. In the case of buildings with gas appliances, you can expect your proposed Source emissions score to be high. Starting with the 2025 Energy Code, New Construction projects are required to comply with all three scores.
Note also that Single Family New Construction projects are also subject to the Peak Cooling limitation that is shown onscreen and must comply with that fourth compliance metric.
Additions and Alterations are only required to comply with the LSCe score.
