Portfolio Summary: Whole Building Data by Reporting Period

Better Buildings Challenge partners strive to report whole-building data for all properties within their portfolio. Often, Multifamily partners face the added challenge of collecting data from tenant-paid utility accounts. The Better Buildings Challenge is working with Multifamily partners and utility companies to improve the data collection and reporting process. While this important work continues, Multifamily partners are being recognized for their successes within those properties that are reporting whole-building data. POAH's portfolio consists of 78 properties, 8,672 apartment units and 6.9 million square feet. For the 2017 reporting period, POAH reported whole-building data for 45% of its portfolio.

Preservation of Affordable Housing

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. POAH's portfolio consists of more than 425 buildings and 6.9 million square feet. Partner has improved energy performance by 11% for its properties reporting whole building data from a 2012 baseline, making progress towards a goal of 20% by 2023.  POAH has decreased its energy usage by employing rigorous efficiency standards during new construction or major rehabs, with a particular focus on high-performance building enclosures, and by leveraging utility incentives and performance contracts for existing properties.  Recent major projects include a property producing most of its energy on site, and multiple cold climate gas-heated properties using over 30% less gas.  POAH maintains efficient building performance across its portfolio through constant monitoring of utility data to identify and respond to energy usage trends, and through its industry-leading Basis of Design tool, which ensures consistent use of energy efficient systems at each building.


Looking at the percent improvement in energy performance across facilities reporting whole building data can provide insight into how an organization is saving energy.  POAH has achieved energy performance improvement of greater than 6% at more than 13 of its properties. There are 8 properties that have experienced an increase in Source EUI.  These properties have been targeted for future energy efficiency improvements.


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. POAH's portfolio consists of properties with  a wide range of baseline EUI values, most of which are from 84 to 189 kBtu/sq. ft. At this time, more than half the properties reporting baseline year whole building data have shown energy improvement since 2012. The properties located near or below the 0% axis may present good opportunities for further savings.
