Granbury ISD

Granbury ISD was faced with many challenges as it related to deferred maintenance and energy efficiency needs and sought the partnership of E3 to craft a plan and financial strategy to address those needs. After exhaustive collaboration and planning, a project was designed to accomplish the following:

• Over 200 HVAC units replaced older than 20 years
• T8 lighting retrofit and lighting control
• District-wide water conservation retrofit
• Field turf installation

E3 designed a program that replaced more than 200 HVAC units older than 20 years and completed a districtwide T8 lighting retrofit with controls.

To minimize disruption to summer classes and normal district workflows, construction was tightly coordinated. This included a notable single-day helicopter lift to place 160 HVAC units across rooftops, allowing summer school and facility cleaning to proceed on schedule. Actual energy savings exceeded expectations, delivering $323,362 in Year 1 ($41,500 over the guaranteed target).

To address the district’s high water bills, E3 designed and performed a comprehensive water conservation retrofit, upgrading restroom plumbing and faucets across campuses. To deliver additional water savings and eliminate intensive maintenance requirements, E3 coordinated the installation of low-maintenance synthetic field turf on the varsity athletic fields.
