Green Investments At Every Opportunity
Design & new construction
Occupancy & operations
End of life
Acquisition/rehab
Demolition
1. Deep green building from the
start
2. Greenest rehab we can afford
3. Incremental improvements

Sometimes, We Make Our Money Back
Really satisfying exterior lighting upgrade of house lights on one
building and corresponding really satisfying 50%+ drop in energy consumption on a single electric

Not Many Mechanisms Available Yet to Resolve
Not in Texas! (yet) On-bill financing? Green leases?
Sophisticated
performance-based utility incentives tailored especially for multifamily?
Not in Texas!

IRS Allows 5 Calculation Methodologies
1. PHA (public housing authority) allowances
2. Local utility estimate
3. Actual use
4. HUD utility schedule model
5. Energy consumption model

PHA Most Common, But We Used Actual Use
Requires: 12 months of actual
consumption data for the utility allowance you want to change
Data for 20% of units from each floor plan

State housing agency unfamiliar with how water rates are applied
Lots of emails & a rather tense in-person meeting

WHY NOT HIGH PERFORMANCE?
• The #1 Excuse: “It’s too expensive.”
• Reality: It doesn’t have to be
• Tools: Integrative design process, modeling, 3rd party verification, commissioning, monitoring, retro-commissioning, education
![Page 41: Strategic Alignments: Renewables, Water, and the Community ... · Really satisfying exterior lighting upgrade of house lights on one building and corresponding really satisfying 50%+](https://reader033.fdocuments.in/reader033/viewer/2022041610/5e36e03b3d027b003b4b0f9b/html5/thumbnails/41.jpg)
TWO APPROACHES TO HIGH PERFORMANCE
1. The Hare Approach: use all the latest and greatest technology with lots and lots of solar PV
2. The Goldilocks Approach: carefully balance cost and performance using the integrated design process
