General requirements • Resiliency• EUI target - Site Energy• Passive House classic - 120kwh/m2 Primary Energy• new Passive House 60kwh/m2 Primary Energy• Site Energy vs Primary Energy

• “Source energy represents the total amount of raw fuel that is required to operate the building. It incorporates all transmission, delivery, and production losses. By taking all energy use into account, the score provides a complete assessment of energy efficiency in a building”.

• “Site energy is the amount of heat and electricity consumed by a building as reflected in your utility bills.”

• “Primary energy is the raw fuel that is burned to create heat and electricity, such as natural gas or fuel oil used in onsite generation”

• Source: https://www.energystar.gov/buildings/facility-owners-and-managers/existing-buildings/use-portfolio-manager/understand-metrics/difference

Passive House US The PHIUS Core Source energy targets are: Non-Residential: 38 kBTU/ft2.yr (110 kWh/ m2 yr)

• Passive House recommendations for the building envelope:

Windows – Passive House recommends window assembly U–value of less than or equal to 0.8 W/(m²K) / [U-0.14 Btu/hr-sq ft°F] including installation thermal bridge. Ug – 0.5 [U-0.088 Btu/hr-sq ft °F] and U assembly 0.8 [U-0.14 imperial]All opaque building components of the exterior envelope must be very well-insulated. Passive House recommends heat transfer coefficient max. U-value of 0.1-0.15 W/(m²K) = [U-0.026 Btu/hr-sq ft °F] for walls and roof U-values.PHIUS+2015 recommended R-values for region 5 are: Wall insulation R-40, Roof R-70, Slab continuous insulation R-20The building envelope also should be built in a very airtight way. For Passive House n50 < 0.6 h-1 is required and < 0.3 is recommended.

General requirements Net zero considerations- Envelope – Passive House strategies – airtight building, super

insulating, - Building orientation and massing, building depth, daylighting,

capturing solar energy where beneficial- Advanced lighting control- Exterior lighting efficiency- All electric? GSHP?- Renewable energy – PV- Define “net zero” - LEED Zero (existing building certification)

General requirements • Resiliency

- Durability, storm preparedness- Flood zone avoidance- Underground parking- Location of critical equipment above 1st level- PV battery storage? (FP considerations)- Light pollution – lighting and site safety- Net Zero / Passive- Heat island effect – cool roof / green roof- Stormwater management- Landscaping – native, rainwater harvesting- Site safety – rain gardens- Biophilia – stress reduction for the occupants

LEED• MSBA • LEED Certified minimum• LEED Silver 2% reimbursement

• Recommended: LEEDv4 with LEEDv4.1 credit substitutions• Proposed scorecard
