Community Housing Partners: Energy performance

PORTFOLIO ENERGY PERFORMANCE

Better Buildings Challenge Partners commit to decrease portfolio-wide source energy use intensity (EUI) and to increase the percent improvement compared to a set baseline. Since 2013, Community Housing Partners has improved their portfolio-wide energy performance by an average of 3.7% each year, which is equivalent to a cumulative improvement of 16% against a 2010 baseline. Energy savings have been achieved by implementing lighting retrofits across all properties, HVAC upgrades at the three largest properties, and an energy awareness program focused on low-cost opportunities for savings.

UTILITY DATA IN MULTIFAMILY PORTFOLIOS

Multifamily property owners often face challenges in gathering whole building data for properties with large numbers of individual tenant-paid utility accounts. Through the Better Buildings Challenge, partners can demonstrate progress towards their savings goal by reporting two types of data: (1) whole-building energy use, including tenant-paid utilities, for at least 30 percent of their portfolio; and (2) owner-paid receipts (common areas only) for the remaining share of their portfolio. Community Housing Partners' portfolio consists of 95 properties and more than 4.5 million square feet and approximately 5,100 housing units, with whole-building data (both tenant-paid and owner-paid receipts) available for 44% of their portfolio.

WHOLE BUILDING VS. OWNER-PAID PERFORMANCE

This graph breaks out the portfolio's energy performance for properties with whole building energy use vs those with owner-paid receipts.  Community Housing Partners has achieved 3.8% savings in properties with whole-building data and 3.5% in properties with owner-paid receipts. 

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.  Community Housing Partners has achieved energy performance improvement of greater than 15% at more than 37 of its properties. There are 27 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.Community Housing Partners' portfolio consists of properties with  a wide range of baseline EUI values, most of which are from 50to 100 kBtu/sq. ft. The majority of properties have shown energy improvement since 2010. The properties located near or below the 0% axis may present good opportunities for further savings.
