Multifamily Energy Audit Protocol For Existing Apartment Communities

A multifamily energy audit is a systematic evaluation of how an apartment community or residential property uses energy and where opportunities exist to reduce operating costs, improve resident comfort, increase building performance, and prioritize capital improvements.

Depending on the property, the evaluation may include utility consumption, the building envelope, heating and cooling systems, domestic hot water, lighting, controls, ventilation, common areas, representative dwelling units, operating practices, and completed improvements. Rather than viewing these systems independently, EcoAudit® evaluates how they work together as a complete building.

Traditional multifamily energy audits often begin with an engineer spending hours collecting information that the owner, maintenance staff, and property management team already know. EcoAudit® MFR reverses that process.

Property personnel complete a guided assessment using a smartphone, tablet, laptop, or desktop computer by answering structured questions, uploading utility bills, photographing building systems, documenting completed improvements, and identifying operational concerns.

EcoPlatform™ applies Contract-First Architecture, building science, engineering expertise, and deterministic analysis to compare the property's documented characteristics against its engineering baseline. Rather than guessing where energy is being lost, EcoPlatform™ determines which building systems no longer match their expected performance and prioritizes the improvements that will deliver the greatest return.

EcoAudit® MFR supports apartment communities, affordable housing, condominiums, student housing, senior housing, mixed-use residential developments, military housing, public housing, and multifamily portfolios.

Because EcoAudit® is built on Contract-First Architecture, the protocol can also be customized for organization-specific requirements, regional programs, or specialized housing types.

Yes. EcoAudit® MFR scales from a single apartment building to large regional or national portfolios. Each property maintains its own Living Building Record while owners, property managers, REITs, and asset managers can compare buildings using a consistent assessment methodology.

EcoAudit® organizes information that may be relevant to Section 45L, Section 179D, utility incentive programs, and other energy-efficiency opportunities. Eligibility depends on the specific property, project, certification pathway, placed-in-service date, and applicable program requirements.

Yes. EcoAudit® was specifically designed to replace the traditional information-gathering phase of an energy audit.

Instead of paying an engineer to spend hours collecting information that the owner, maintenance staff, and property management team already know, EcoAudit® empowers those individuals to document the property by answering guided questions, uploading utility bills, photographing building systems, identifying completed improvements, and describing operational concerns.

EcoPlatform™ analyzes that information using Contract-First Architecture, building science, engineering expertise, and deterministic analysis to determine where energy is being wasted and prioritize the improvements that will restore performance. Engineering knowledge is embedded within the platform instead of requiring every building to start with a manual information-gathering exercise.

When specialized testing or additional engineering analysis is beneficial, it can be focused on answering specific technical questions rather than rediscovering information that was already available.

Completing EcoAudit® is only the beginning.

The submitted information becomes part of EcoPlatform™, where building science, engineering expertise, and deterministic analysis are applied to prioritize improvement opportunities based on expected performance, implementation cost, operational impact, and available incentives.

Approved improvements can then move into RetroCore™, where projects are developed, managed, documented, and added to the property's Living Building Record for future planning, budgeting, and performance analysis.

Unlike a traditional energy audit that ends with a report, EcoPlatform™ continuously builds upon what is learned about a property over time.

Equipment replacements, envelope improvements, lighting upgrades, utility history, inspections, warranties, photographs, incentive documentation, and completed retrofit projects become part of the property's permanent Living Building Record.

Future analyses no longer begin with a blank slate. They begin with an accurate history of the property, allowing recommendations, budgeting, capital planning, and retrofit decisions to become more accurate with every completed improvement.

The time required depends on the number of buildings, dwelling units, systems, utility accounts, and available records. EcoAudit® eliminates the traditional technician-led information-gathering visit, allowing the property team to complete the guided assessment in manageable stages.

The apartment energy assessment may use property and building details, unit counts, occupancy information, utility bills, equipment data, operating schedules, photographs, maintenance concerns, comfort complaints, capital plans, and records of completed improvements.

The assessment can be completed by the owner, property manager, maintenance supervisor, facility team, asset manager, or another person familiar with the property. Multiple team members can contribute the information they know best.

Yes. EcoAudit® MFR was designed for existing and occupied apartment buildings. The guided process allows property teams to document representative units, common areas, central systems, operating concerns, and completed improvements while minimizing disruption to residents.

Savings depend on the building's age, construction, systems, utility use, operating practices, deferred maintenance, and completed improvements. EcoPlatform™ determines where building performance has diverged from the property's engineering baseline and prioritizes improvements according to their expected energy, cost, comfort, and operational impact.

An apartment building energy assessment can include utility use, dwelling units, common areas, the building envelope, HVAC, domestic hot water, lighting, controls, ventilation, laundry, elevators, amenities, moisture, comfort, resilience, renewable energy, electrification, and completed improvement records.
