Energy Flows & Future Energy

Narrative: 

 

A 200.6 kW photovoltaic array provides for 26.8% of the building’s power requirement. This public-private joint venture with CPS Energy has enabled the utility to test the viability of solar energy application in large, commercial applications, and has led the utility to expand its offerings for rebates and programs associated with solar energy. This project also serves as an educational opportunity for the community, which is invited to learn about the array and the other sustainable features of Full Goods and Pearl at the solar array building dashboard kiosk or on the website.

 

The structure’s roof is comprised of white membrane and galvanized metal, both of which reflect South Texas’s intense summer radiated solar heat and reduce interior heat gain.

 

A third-party mechanical consultant was hired by the owner to commission the mechanical and electrical systems in the building including water heaters, lighting controls, air conditioning, and photovoltaic systems. The engineers reviewed all of the plans and system designs prior to construction, tested the systems when first installed with great care to ensure they were running at optimum energy, and then rechecked 10 months later.
