Heated Garage Update
Since the last update of the MN Overlay in April 2014, we learned that ES MFHR will not allow heated garages under multifamily apartment buildings four stories or more in height. Therefore, applicable projects will not be certified by ES MFHR and will not meet the mandatory building performance requirement of Criteria 5.1b.
To address this issue with projects that we currently fund, we are amending Criteria 5.1b in the MN Overlay and in the 2011 Enterprise Green Communities as follows:
Omit the current clarification in the MN Overlay and replace with the following:
Minnesota Housing will allow underground heated garages in projects 4 stories or more if the following requirements are met:
1. The building(s) shall be designed to be at least 15% better than ASHRAE 90.1-2007
2. A garage energy penalty must be included in the Performance Path energy model. Under this penalty, the garage in the Baseline Building energy model may not be heated and must be modeled with an insulated garage ceiling.
3. The project shall register with and follow the ES MFHR submittal and tracking process.
4. Testing and verification per the ES MFHR shall be provided during construction.
