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. Clark County's portfolio consists of more than 100 buildings and 3 million square feet. Clark County has improved energy performance by 9% from a 2013 baseline, making progress towards a goal of 20% by 2023. Energy savings have been achieved by implementing lighting retrofits, solar photovoltaic installations, HVAC upgrades and an energy awareness program focused on low-cost opportunities for savings.

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. Clark County has achieved energy performance improvement of greater than 10% at 37 of its properties. There are 24 properties that have experienced an increase in Source EUI. These properties have been targeted for future energy efficiency improvements including LED lighting retrofits and energy audits performed in conjunction with the local utility. 

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. Clark County's portfolio consists of properties with a wide range of baseline EUI values, most of which are from 50 to 300 kBtu/sq. ft. The majority of properties have shown energy improvement since 2013. The properties located near or below the 0% axis have been targeted for good opportunities for further savings and included in capital budgeting plans.
