  • Brooks-City Base Preliminary Energy Audits
    Client: Brooks Development Authority
    Completion: 2010

    Preliminary Energy Audits, Brooks-City BasePreliminary review of buildings at Brooks-City Base for the purpose of creating a Memo of Understanding (MOU) to apply to the State Energy Conservation Office (SECO) for a loan through the LoanSTAR program. Performed an energy audit of 10-15 buildings that were prime candidates for energy conservation; reviewed design drawings of existing systems and evaluated major systems and equipment in use, as well as measurements and costs of energy usage. Calculated expected energy savings of select projects using the SECO LoanSTAR simplified calculation or other approved methods.

  • UTSA University Center Solar PV System
    Client: UTSA
    Completion: 2011

    Solar PV System, University Center, University of Texas at San Antonio UTSA received $1.08 million in Department of Energy stimulus funds distributed by the State Energy Conservation Office (SECO) to install solar panels on two buildings at UTSA's Main Campus. The project for UTSA was made possible because of the solar-energy grant that is one of four that will enable solar panel installations in San Antonio. CPS Energy will participate in the UTSA solar initiative to create opportunities for the students to work on the project; $127,720 is pledged from the solar rebate program for student scholarships. UTSA will install the solar panels on the roofs of the University Center's recent expansion and the Engineering Building on the Main Campus. The panels are expected to reduce carbon dioxide emissions up to 273,661 pounds annually, which is the equivalent of planting 372 acres of trees. They also are expected to generate 237 megawatt hours of energy, saving UTSA as much as $64,000.00 per year. Alderson & Associates provided engineering services for the development of an RFP to allow UTSA to solicit interested solar contractors to provide a turnkey project of system design and installation of a 140 KW photovoltaic solar system on the roof of the University Center III Building and a total of 12 KW photovoltaic system on the roof of the Engineering Building. The RFP consisted of drawings depicting as-built conditions of the roofs, mechanical penthouses and electrical penthouses. The drawings indicated the allowable area for the solar panel installation and acceptable structural loading of the roofs. Commissioning services included closeout activities with the observation of the complete power quality process and review of project closeout documentation (Operations & Maintenance Manuals, training, warranty transfer and record drawings).
