Houston, TX: Energy performance

Cumulative (vs. Baseline)18%
Annual (2018)-2%
PORTFOLIO ENERGY PERFORMANCE

Better Buildings Challenge Partners strive to decrease portfolio-wide source energy use intensity (EUI) and to increase the percent improvement compared to a set baseline. Houston's public portfolio consists of 290 buildings and 7 million square feet. Houston has improved energy performance by 18% from a 2008 baseline, making progress towards a goal of 20% by 2021. Energy savings were achieved by retrofitting 6 million square feet of municipal buildings with more efficient mechanical equipment and implementing lighting retrofits across many properties. The City has started to develop energy awareness programs that will utilize behavior change campaigns to reduce energy consumption.

ENERGY PERFORMANCE BY PROPERTY

Looking at the percent improvement in energy performance across all facilities can provide insight into how an organization is saving energy. Houston has achieved energy performance improvement of greater than 15% at 50 of its properties. There are 64 properties that have experienced an increase in Source EUI.  These properties have been targeted for future energy efficiency improvements.

IDENTIFYING OPPORTUNITIES FOR IMPROVEMENT

Property-level energy performance metrics, including EUI and percent improvement to date, are critical to track progress over time and identify opportunities for additional energy savings. Houston's public portfolio consists of properties with a wide range of baseline EUI values, most of which are from 200 to 400 kBtu/sq. ft. The majority of properties have shown energy improvement since 2008. The properties located near or below the 0% axis may present good opportunities for further savings.
