Multifamily Services

High-Performance and Green Building Certifications

Energy Diagnostics provides consultations, inspections, testing, and third-party verification for multifamily energy code services to ensure builders meet or exceed required energy code regulations. 

Our team is particularly adept at providing developers and architects with the mandatory energy services associated with LIHTC and QAP-funded projects. Regardless of whether your project is seeking 4% or 9% tax credits, we are able to help guide you through the program specifically helping you satisfy the utility allowance schedule for tenant-paid utilities as well as the energy modeling for ensuring the project meets the energy requirements. Multifamily energy code services are essential for builders and developers looking to maximize their return on investment. We will work to guide you through the path to achieve code compliance or above-code certification in order to maximize tax credits and utility rebates.

Our consultative approach provides guidance on various above-code certification programs to determine the path that will help your team move from application through funding with ease. Our team is able to provide both the energy and sustainability inspections as well as HVAC design meaning that the process is more direct and streamlined for you. 

Above Code Green Building Certification Paths

Energy Efficient New Build

To earn ENERGY STAR certification, a new home or apartment must meet strict energy efficiency requirements established by the Energy Star Residential New Construction program. Certification through Energy Star provides a clear path towards receiving substantial tax credits, specifically the 45L energy-efficient tax credit.

HERS Rating

The Home Energy Rating System (HERS) Index is the industry standard by which a home’s energy efficiency is measured. It is also the nationally recognized system for inspecting and calculating a home’s energy performance. A certified Home Energy Rater assesses the energy efficiency of a home, assigning it a relative performance score. The lower the number, the more energy efficient the home. 

Apartment building

Enterprise Green Communities is the nation’s only national green building program designed explicitly for green affordable housing construction. All projects seeking Green Communities Certification must meet mandatory criteria.


The National Green Building Standard (NGBS) is the first residential green building rating system to be approved by the ANSI as an American National Standard. NGBS Green Certification verifies that a home, building, or land development is designed and built to achieve high performance in six key areas: Site Design, Resource Efficiency, Water Efficiency, Energy Efficiency, Indoor Environmental Quality, and Building Operation & Maintenance.

LEED Certification

LEED (Leadership in Energy and Environmental Design) is the most widely used green building rating system in the world. Available for virtually all building types, LEED provides a framework for healthy, highly efficient, and cost-saving green buildings. LEED certification is a globally recognized symbol of sustainability achievement and leadership.
