Energy Efficiency

The ICC recently released its schedule for the development of the 2021 Group A I-Codes and 2022 Group B I-Codes.

Energy efficiency is many things to many people, encompassing a wide range of technologies and approaches, from building insulation or LED lightbulbs to vehicle fuel economy or manufacturing practices.

A renewed need for medium-density housing within and surrounding East Coast cities, and economic pressures following the recent recession, have led to an increased use of economical wood-framed construction in large, multi-story residential buildings.

Cavity insulation goes between (and is interrupted by) framing whereas continuous insulation is continuous and not interrupted by framing other than fasteners or service openings. 

A new “open file” research report has just been completed to assess the role of building science and healthy buildings in relation to controlling the risk of health threats such as the COVID-19 pandemic. 

As mentioned in a prior January 2020 EEBS article (2021 I-Codes Adopt Major Energy Efficiency & Building Science Advancements), many advancements forthcoming in the 2021 ICC family of codes (energy and building codes) were overviewed with the intent to address these advancements individually in future articles.

Without clear definitions the code may be subject to varying interpretations that may depart from the intent. Definitions are important and they have significant technical implications.

The 2021 International Codes are currently going through our established validation process, conducted in accordance with Council Policy 28.

At the recent 2020 RESNET Building Performance Conference, Jay Crandell (ARES Consulting) and Amy Schmidt (DuPont) gave a presentation titled “If Walls Could Talk…”

The energy subcommittee of the House Committee on Energy and Commerce heard discussion on six bipartisan efficiency and energy storage bills, but the most contentious moment focused on appliance standards.
