Nebraska & Iowa

2. Sustainable & Affordable Housing
• Across the U.S. more environmentally
sustainable public housing has come online
in the last 2 years
• Over 180,000 Energy Star certified multi-
family units.
• Over 130,000 LEED multi-family units
• Over 331 Passive House multi-family units

5. Commissioning: HERS Index
• Reference is 2006 code
built house (100)
• Each point = 1% annual
energy consumption gain
or lose
• 0 = net zero energy house
• Advantage: scores the
structure not the
occupants
• Disadvantage: doesn’t
score the occupants.

6. Energy Star Homes
https://www.energystar.gov/index.cfm?c=new_homes.hm_index
• Best building standard
widely available
• 4 checklists : HVAC,
Thermal Enclosure,
Water Management
• HERS Rating better
than code

18. LEED-H Requirements
• HERS Rating <70 (local code dependent)
• EPA Energy Star Certified
• EPS Water Sense Certified (v4)
• Simulated Energy model
• Door Blower test
• Duct Leakage Test
• Thermal Barrier Verification
• Thermal Bridging Verification

23. Local Incentives
1. Property Tax Abatement – Most common
2. LIHTC – Low Income Housing Tax Credit
Many local municipals require or offer
additional points for green certification for
LIHTC developers
3. Local market driven (Portland, Seattle)
4. Nonprofit Driven (Habitat for Humanity)
5. Stick vs carrot - local municipals demand it

24. Example: Cincinnati, OH
1. Offers residential property tax abatement
for units that meet LEED certification:
- Max abatement of $275,000 for up to 15
years
- Unlimited property tax abatement for up
to 15 years for LEED Platinum.

25. LIHTC Example: Virginia
1. Allows LIHTC investors to reduce their
federal income tax by $1 for every $1 of tax
credit they received. Limited to $1.75/state
resident.
2. Provide additional “credits” for green
housing (LEED-H, EarthCraft, Passive
House, etc.)
3. Offer additional “credits” for energy efficient
housing (lower HERS score).

LIHTC Green Standards

27. Passive House By the Numbers
• 4 multi-family complexes have been
certified to meet the Passive House
standard of the Passive House Institute of
the U.S. (PHIUS)
• 17 more multi-family complexes have been
submitted to PHIUS for certification
• 331 units total.

28. Summary
1. Heartland multi-family housing units are not
as sustainable or as energy efficient as their
peers across the region or country.
2. Many Heartland developers and builders
are leaving financial incentives “on the table”
by not developing more sustainable housing
units.

29. Summary
3. Next generation housing tenants will expect
more energy efficient and sustainable housing
options.
4. Greater emphasis on energy efficiency or
sustainability by the LIHTC and tax abatement
policies and utilities could greatly impact the
market place as it has in other markets.
