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. Parkway Houston's portfolio consists of 19 properties and more than 8.5 million square feet. Parkway has improved energy performance by 9% from a 2016 baseline, making progress towards a goal of 20% by 2026.  Parkway has funded numerous projects to upgrade major HVAC equipment and overhaul aging central plants across our portfolio. We continue to retrofit buildings with LEDs as we have turnover and encourage tenants to include LEDs in their tenant improvement projects. In 2020, we replaced 44 air handling units to continue the push toward efficient mechanical equipment.

*Energy consumption for all time periods was normalized to reflect occupancy levels during COVID-19 disruptions.

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. Parkway Partner's has achieved energy performance improvement of greater than 10% at 10 of its properties. There are 5 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. Parkway's portfolio consists of properties with a wide range of baseline EUI values, most of which are from 125 to 200 kBtu/sq. ft. The majority of properties have shown energy improvement since 2016. The properties located near or below the 0% axis may present good opportunities for further savings.

PORTFOLIO WATER PERFORMANCE

Better Buildings Challenge Partners strive to decrease portfolio-wide source water use intensity (WUI) and to increase the percent improvement compared to a set baseline. Parkway Houston's portfolio consists of 19 properties and more than 8.5 million square feet. Parkway has improved water performance by 25% from a 2016 baseline, making progress towards a goal of 30% by 2026.  Parkway has continued to retrofit buildings with low-flow valves and aerators. We continue to evaluate projects that would increase overall water efficiency, and where possible we require tenants to install leak detection systems with new buildouts. We are also continuing to explore opportunities to improve irrigation water efficiency through measures such as additional smart irrigation systems and drip irrigation. 

*2020 water consumption may be significantly lower than a typical year since buildings experienced reduced occupancy as a result of COVID-19 disruptions.
