Zero Energy House Case Study
Guadalupe-Saldaña Net Zero Subdivision, TX
Rendered Image, by Travis G. Young, Studio Momentum
The project is the first 100% affordable housing, net-zero energy community project in the State of Texas, possibly the nation. A total of 90 homes including single-family, two-family, and town home dwellings will be developed. The units will range in size from 650 sq. ft. (one bedroom, one bath) to 2000 sq. ft. (five bedrooms, 2.5 baths). Every unit on this property will be affordable at 80% or below MFI for homeowners and at 60% or below MFI for renters.

Site:
The subdivision located on a previous brown field used for waste disposal. Upon this condition, one of the consideration in site planing is to effectively use the available site, maximizing the solar panel exposure while minimizing the solar heat gain.
Net Zero Related Techniques:
- Design
- Mechanical System
Space cooling / heating: Geothermal heat pump
Water heating: solar thermal
-Material
Insulation: Open-cell spray foam insulation
-Construction
Phase I project:
This phase consists of 4 building structures of 8 rental units.
