Passive House Incentives

Take Energy Efficiency to a New Level

The Sponsors of Mass Save® are offering incentives and assistance to support the construction of multi-family high-rise buildings (four stories or higher) with deep energy savings. Certification and performance incentives are available to assist builders and developers in achieving Passive House certification or similar levels of efficiency.

Passive House building techniques address energy usage and resiliency resulting in significant and long-lasting primary energy savings compared to homes built to conventional building codes. We provide technical support in the form of feasibility studies and energy modeling as well as financial incentives to cover the incremental cost of building to, or exceeding, Passive House standards. We structured our offerings to reduce the risk a developer may perceive in pursing Passive House by staggering incentive payments throughout feasibility, design and construction phases.


What is Passive House?

Passive House refers to the ultimate goal in high efficiency design: buildings that minimize energy consumption and have added comfort and durability features. Passive House design focuses on robust insulation and air tightness, high-performing glazing, and simplified mechanical systems, to achieve significantly lower energy use, while creating a comfortable and durable space for inhabitants. The Passive House Institute (PHI) and the Passive House Institute US (PHIUS) establish two independent standards and provide certifications for such homes: The PHIUS+ Passive Building Standard and the international Passive House Standard.


How Incentives Are Calculated

The Sponsors of Mass Save support Passive House and related high-efficiency construction in Massachusetts through enhanced incentives. There are incentives for multi-family buildings (four stories or higher) that achieve certification through PHI or PHIUS, or those that pre-certify and build to high efficiency without obtaining certification.


We will follow the incentive structure detailed below and offer incentives for pre- and post-construction activities once all requirements are met. If you don't qualify for the Passive House incentive offering, it will replace the standard Multi-Family High-Rise incentives.

Passive House Incentive Structure for Multi-Family Mid- and High-Rise
Incentive Timing Activity Incentive Amount Max. Incentive
Pre-Construction Feasibility Study 100% Feasibility costs $5,000
Energy Modeling 75% of Energy Modeling costs $20,000
Pre-Certification $500/unit N/A
Post-Construction Certification $2,500/unit
Net Performance Bonus $0.75/kWh
The Net Performance Bonus is calculated by determining the final pay for saving incentives and subtracting the pre- and final certification incentives. The result is the Net Performance Bonus.
Projects that pre-certify but do not achieve certification are eligible for the pre-certification incentive and Net Performance Bonus.
Projects over 100 units must be pre-approved by the applicable Sponsors of Mass Save.

Are You Eligible?

The incentive is available to projects that enroll during the early stages of design, prior to reaching 100% Schematic Design. Eligible projects are Multi-Family High Rise projects, four stories or higher and with five or more units, that are pursuing Passive House certification and agree to monitor and provide the Sponsors with whole-building gas and electric consumption as well as on-site generation production. Participants must hire a Passive House consultant certified through either PHI or PHIUS to conduct a feasibility study and to serve as consultant throughout the design and certification process. You are eligible to receive post-construction incentives if your building achieves at least pre-certification. If pre-certification is not achieved, you are eligible to receive the standard Multi-Family High-Rise incentives.


Passive House Training

The Sponsors of Mass Save are also partnered with Passive House Massachusetts, to launch a Passive House training offering to support workforce development and market transformation in the energy efficiency and building construction industries.
