HECS has certified 45L projects across Clarksville for builders, developers, and CPA syndicators since 2018. Project types include single-family subdivisions, townhomes, low-rise multifamily, and qualifying apartments meeting ENERGY STAR or Zero Energy Ready Home standards.
Yes. HECS field technicians hold RESNET QES (Qualified Energy Specialist) credentials, which is the certification accepted by IRS for 45L Energy Efficient Home Credit certification under IRC §45L through PL 117-169. We sign IRS Form 8908 as the certifying provider.
45L credits are tiered: $2,500 per unit for ENERGY STAR-certified homes, $5,000 per unit for Zero Energy Ready Homes (ZEHR), with additional bonus credits for prevailing-wage + apprenticeship projects under PL 117-169. Most Clarksville multifamily projects qualify for $2,500-$5,000 per unit.
Most 45L certifications in Clarksville complete in 4-8 weeks from contract: 1 site visit for performance testing + 2-4 weeks desktop review of the energy model + HERS Index documentation.
Yes. If your project already has a HERS rater of record, HECS works alongside them for the energy model review + inspection verification. If no rater is engaged, HECS can serve as the QES certifying provider on the Form 8908.
HECS needs: (1) the energy model + HERS Index for each unit type, (2) built-as construction drawings if they differ from the model, (3) the property address + building permits + occupancy date. We audit, request clarifications, and prepare the Form 8908 for the CPA to attach to the tax filing.
