Spring into Action and Build Green

By Hector Martinez and Beth Keel

Spring is upon us — a new season that brings warmth and renewal. Nature springs to life, and we at the Opportunity Home San Antonio (Opportunity Home) are strongly committed to going above and beyond in reducing our carbon footprint on the environment, and making our housing communities — and all of San Antonio — a cleaner, safer place to live and work.  

From recycling programs, to lead-based-paint and asbestos abatement projects, to creating the newly opened Garcia Street Urban Farm, to energy-reducing retrofit construction and green-certified capital improvement projects and new multi-family developments, Opportunity Home’s efforts citywide are producing real, measurable results.

In 2018, Opportunity Home was recognized by Build San Antonio Green (BSAG) for achieving more than a million square feet of certified green space. Before that Opportunity Home was recognized by the United States Department of Energy for a Senior/Disabled downtown midrise renovation project that resulted in significantly lower energy consumption. Also, in 2016, Opportunity Home was invited to the White House to participate in a roundtable discussion on energy opportunities for low-income families, something Opportunity Home continues to provide every day.


Opportunity Home previously volunteered to enter into the Department of Energy’s (DOE) “Better Buildings Challenge” (BBC), a voluntary leadership initiative through which Partners – including companies, universities, school districts and municipalities – make a public commitment to achieve lasting, organization-wide energy savings. Partners in the Better Buildings Challenge commit to achieve significant energy savings established by a specific energy savings goal. Goals encompass over 2,000,000 square feet of Opportunity Home’s portfolio and strive to achieve at least 20 percent reduction in energy consumption over 10 years. Opportunity Home continues to track and verify progress toward these energy savings goals.

Partners challenge commit to track and verify progress toward energy savings goals by following a common process:

  • Baseline: Progress is tracked against a baseline year, which is selected by Partners within the parameters of program requirements. The baseline year is a reference point in time in which the energy reduction will be measured against. Opportunity Home’s baseline BBC baseline year is dependent on the upgrades of the building.

  • Energy Tracking Software: Opportunity Home is enrolled in an EPA database called Energy Star Portfolio Manager. 

  • Reporting: Progress toward energy reduction goals will be tracked by DOE. Partners benchmarking in Portfolio Manager can share access to their account with DOE. 

  • Metrics: Energy use metrics are expressed in terms of source energy use intensity (EUI). For commercial buildings, energy use intensity is tracked in terms of energy use per square foot. 

  • Verification: Energy data and operating characteristics is reviewed to ensure completeness and accuracy. Data is independently verified for a random sample of Partner properties to maintain integrity of program results.  

  • Energy Performance Results: Progress toward goals is displayed for all Partners in the Energy Performance section of the Better Buildings Challenge website.


Energy Performance Contracting (EPC) is an innovative financing technique that uses cost savings from reduced energy consumption to repay the cost of installing energy conservation measures, and allows the Housing Authority to invest those savings back into those communities in capital improvement projects. This innovative financing technique allows agencies to achieve energy savings without upfront capital expenses. 

Typical energy conservation measures include LED lighting, insulation, energy efficient windows, high efficient and more. 

Opportunity Home has partnered with the Denver Housing Authority through an inter-agency agreement, in order to develop Opportunity Home’s first-ever Energy Performance Contracting project. This first-phase EPC included a total of 1995 units at five of Opportunity Home’s largest communities: Lincoln Heights (338 units) and Cassiano Homes (499 units), Alazan Apache Courts (741 units), Fair Avenue Apartments (216 units) and the Villa Tranchese Apartments (201 units). In addition, Opportunity Home received approval from HUD to administer this contract as a “self directed” contract. At the time, the only EPC self directed EPC contract by a housing authority in the state of Texas. This allowed Opportunity Home to save hundreds of thousands of dollars in fees from a third party.

Phase II EPC is scheduled for 2020, where Opportunity Home will invest in the installation of various energy conservation measures at more than 34 developments, including more than 2,300 Public Housing units, with projected savings of more than $9 million through the life of the program. Between Phase I and Phase II of Opportunity Home’s EPC, the projected annual energy savings are equivalent to eliminating 5,665 metric tons of greenhouse gas emissions. This is similar to the emissions associated with powering 653 homes for a whole year.*

Opportunity Home is proud to be a leader in the community in preserving and protecting the environment, lowering energy and water consumption, and overall reducing our own carbon footprint in San Antonio. Most importantly, the health, safety and comfort of our clients remains the priority, and these efforts help us achieve those goals.
