RESOURCE LIBRARY

The rental housing sector faces more challenges than nearly any other sector when it comes to improving efficiency and sustainability. Below, the RentLab team has assembled a wide range of resources to help our partner communities strengthen their efforts to make rental housing better.

The impact and findings of data transparency policies

Energy disclosure requirements and other data transparency efforts have had varied impacts on building efficiency.  Study findings are summarized in brief below.

Impacts on Energy Use

Portland, OR 2018 benchmarking policy summary report: benchmarked buildings have shown a 3.5% decrease in energy use per square foot since data was first reported, with some building types (grocery stores, strip malls) showing declines in energy use of more than 10 percent.

Seattle 2016 benchmarking policy summary report: Seattle likewise saw a decline in energy use per square foot of close to 4%, with some sectors seeing declines of 7 percent.  

Relationship between Energy Use and Building Age

Earlier findings (also here) from Portland's program found that building age was not a clear determinant of energy performance.  Seattle saw a similarly complex relationship between building age and efficiency (see here and here).

Rental efficiency programs and policies

Better Rentals, Better City:

Rental properties make up 50% or more of most large cities’ residential building stock, and are less likely to undergo efficiency upgrades since the person paying for the upgrades isn’t the person benefiting from the lower utility bills and increased thermal comfort. This paper describes the benefits of minimum efficiency standards for rentals, profiles the City of Boulder’s pioneering implementation of this policy approach, and describes how other cities can implement such a policy.

Rental housing efficiency: research findings

Energy efficiency and its relationship to household income in multifamily rental housing: Multifamily rental housing expends 37% more energy per square foot than owner-occupied multifamily housing, 41% more than single-family renter-occupied homes, and 76% more than single-family detached owner-occupied homes. In 2009, multifamily rentals averaged 34% fewer energy efficiency features than the number found in other types of housing.

Does green pay off?   Based on an evaluation of LEED- and Energy-Star-certified commercial buildings, the authors conclude that green investments do pay off.
