NEED FOR REHABILITATION AT YEAR 15 CONVERSION:
- Water penetration and moisture damage, including dry rot and mold
- Site drainage and stormwater management issues
- Long-term structural and building systems integrity
- Upgrades for energy and water efficiency

HOW TO MAKE THE REHAB GREENER?
Inherently, preserving and renovating existing housing stock is the most sustainable method of building, especially if located in a walkable neighborhood near to amenities.

Focus first on the building envelope and major exterior systems for long-term durability and integrity of the structures

Part of this includes “weatherization” upgrades, such as new windows and insulation, which improves energy efficiency. Other energy improvements, such as Energy Star lighting fixtures and new water heaters, helps to decrease overall energy use.

Improved ventilation through both mechanical and passive strategies to increase air flow and reduce moisture and mold in units.

Site drainage and stormwater management improves project sustainability.

Reducing lawn area and replacing with low maintenance native plantings further reduces water consumption and adds a more cheerful landscape motif.

If possible, incorporate renewable energy, although in most cases solar energy is prohibitively expensive for affordable housing projects without additional grants.

An additional bus stop makes it easier for residents to utilize public transportation, and incorporates the existing school bus system.

GREEN REHAB SUCCESSES
Less water consumption on site and in units
Minor energy savings in utility data (5-10%)
No mold or mildew in units (blower door testing shows air flow beyond ASHREA thresholds, when previously there was much too little)
Healthier indoor environments (anecdotal health survey shows a reduction in asthma attacks in children who live at Nuevo Amanecer)
Solar panels provide 90% of electricity for community laundry room

GREEN REHAB CHALLENGES
Residents are colder, due to increased air flow through ventilation strategies. Could increase electricity use in future, FHDC is monitoring.
Residents also think the lack of carpets contributes to their unit feeling colder, which is probably true, although removing the carpets was part of the indoor air quality improvement strategy.
Even though the solar array demonstration is saving money, the pay back period is close to 17 years, which isn’t a very sustainable model for a non-profit.
Water is still our largest property expense, and more efforts need to be made to reduce water consumption through grey water reuse and rainwater harvesting systems.
IT’S EXPENSIVE
