Energy Efficiency

As we reported in January, the Group B 2021 I-Codes contain a number of significant improvements in the realm of energy efficiency and building science.

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.

DAP’s newest wall & floor sealant, the Sound Block E90, is designed specifically to reduce sound transmission through penetrations in wall and floor systems, as well as improve STC ratings in sound-rated applications.

Huntsman Corporation today announced that it has branded its world leading spray polyurethane foam (SPF) Business as Huntsman Building Solutions (HBS).

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.
