NEW CONSTRUCTION & MAJOR RENOVATIONS
Step 2 – EUI Target Setting and Developing a Roadmap to Meet the EUI Target
The target EUI for projects participating in this pathway is a site EUI of 25.0 or less or an alternative percent reduction
target in accordance with key customer commitment number 1 above.
• Projects pursuing an EUI of 25 or less – Mass Save Sponsors will engage a ZNE specialist to provide technical
assistance and ZNE planning throughout design
• Projects pursuing the 25.0% or 40.0% reduction scenarios – Mass Save Sponsors will engage a ZNE specialist
to help determine a 25.0% or 40.0% EUI reduction target. The specialist will also help the design team with
developing strategies and a pathway for getting the design to achieve the target.
Once the Mass Save Sponsors confirm the customer is eligible for participation in this ZNE pathway, customers will be
required to sign an Engineering Services Agreement (ESA) and commit to cost sharing the services of the ZNE specialist.
Step 3 – Design
Once the EUI target is established, this EUI target should be written into the project documents, including the OPR, where
it will serve as a touchstone throughout the rest of design and construction. The project team will pursue the EUI target
throughout design and will conduct the iterative energy modeling necessary to ensure the design remains on track to
achieve the target EUI.
In addition to the feasibility and early schematic design technical support and ZNE road mapping services, the Mass Save
ZNE specialist will review the project documents at the end of Schematic Design and at mid design development, and
then will provide reports back to the team with any further recommendations and considerations.
Customer must make final cost share payments to the ZNE specialist once the ZNE specialist’s work is complete at the
end of design development.
Customer must ensure a commissioning contract is in place that meets the requirements of this Program. Provide a copy
of the commissioning scope of services to the Sponsors of Mass Save.
If the customer is pursuing an EUI target through the 25.0% or 40.0% reduction from Mass Save baseline option, the EUI
target will be estimated during the early feasibility and schematic design phases, but will not be locked in for purposes of
incentives until the Mass Save Sponsor confirms its baseline EUI based on the 100% Design Development set. Once the
Sponsors of Mass Save have reviewed that set, the Sponsors of Mass Save will lock in the target EUI. The target EUI will
remain locked for purposes of incentives unless there are major design changes between 100% design development and
100% construction documents, including, but not limited to, HVAC system type changes and space type changes.
Step 4 – Planning for EUI Data Collection and Corrective Action
Customers must consider how they will determine the post occupancy EUI of the project in coordination with their Mass
Save Sponsor(s) and determine who will be responsible for collecting the data. Thought should be given to corrective action if
at post occupancy the project is straying from the final design EUI. The project must comply with ASHRAE 90.1-2016, para.
8.4.3 related to metering and data storage, and it is recommended that the project team consider submetering in
accordance with the LEED BD&C v4 Energy and Atmosphere Advanced Energy Metering credit, which requires submetering
of any individual energy end uses that represent 10% or more of the total annual consumption of the building.
An optional Verification Incentive is available to help customers identify issues that may arise related to energy savings
post construction (please request the Mass Save Sponsor’s scope of work for more details). The Sponsors of Mass Save
will reimburse 50% or up to $10,000 of the fee associated with this work. Customers must decide during design if they
wish to pursue this incentive so that a contract can be put in place.
Step 5 – Mass Save Incentive Pre-Approval
At the end of design, the design team must complete a final energy model representative of the final design. If the design
team’s energy model arms the design will achieve the target EUI, the Mass Save Sponsor(s) will pre-approve an incentive
of $1.25/sf. If the customer has a contract in place for the Verification Incentive scope, this incentive component will be
pre-approved as well.
An additional $1.00/sf incentive will be available after the one-year post occupancy period if the project achieves the
target EUI in practice (see Step 7 for details on when the post occupancy period begins). If the design team’s model does
not achieve the target EUI (either a 25.0 EUI or a 25.0%/40.0% reduction in EUI from the Mass Save baseline), the project
will shift out of the Path 1 ZNE/Deep Energy Savings participation pathway into the Path 2 Whole Buildings EUI Reduction
Pathway (contact your Mass Save Sponsor(s) for more details).
