February 2, 2021 - The residential Zero Energy (ZE) market continues to grow across the United States and Canada, according to the TEAM ZERO 2019-2020 Zero Energy Residential Buildings Inventory. The study, which shows significant increases in multifamily units and overall energy performance, was released by TEAM ZERO, in cooperation with the Energy and Environmental Building Alliance (EEBA).
The new report documents an increase in total Zero Energy projects to 27,965 units from the previous 22,146 units in 2018. These single and multifamily units are working to achieve Zero Energy performance in design, construction, and/or operation.
In this survey, TEAM ZERO uses six years of inventory collection to discuss the development of ZE homes with different climates, energy sources, and project scopes. The survey provides findings on Zero Energy residential design and construction activity, including developments in the process of achieving Zero Energy. ZE buildings aim to produce the same amount of renewable energy as they consume through high levels of energy efficiency.
"The almost 28,000 projects provide a proven template for the success of high-performance technologies and building innovations being successfully adopted today," said Aaron Smith, CEO of EEBA and Board Treasurer of Team Zero.
Additional findings include:
Multifamily projects comprise 75% of the total ZE residential inventory. In the US, multifamily units make up 73% of the country's ZE stock, a notable increase from 67% in 2018. Canada maintained its 90% share of multi-family projects in its total ZE inventory.
Findings show a significant rise in overall energy performance. The ZE category grew by more than one-third over the past year from 29% of units to 38.6%, the majority of which are ZE-ready.
In 2019-2020, California grew its lead in the number of ZE projects (10,959 units) and Colorado increased its ranking from 7th to 5th place (1,311 units).
For the first time, TEAM ZERO's inventory report incorporates data related to fuel types, energy system analysis and "Off-Grid" homes.
