Indoor Air Quality Becomes A Bigger Issue Article originally posted on Multifamily Executive on May 20, 2020 Before the onslaught of COVID-19, the building industry was already developing procedures and products for improving indoor air quality. Building envelopes have become much tighter as triple-pane windows, insulated garage doors, and energy recovery ventilators became more common in new homes and remodeling projects. As concerns about interior air quality become more intense, builders and developers may be called upon to provide answers about how healthy their new homes and apartments actually are. Filter companies and HVAC manufacturers have already started to make products that will help them make their mark on the healthy homes of the future. According to the U.S. Environmental Protection Agency, Americans spend 90% of their time indoors, and indoor air is typically two to five times more polluted than outdoor air. To establish a baseline of how compromised interior air might be, homeowners or would-be homeowners can compute a Hayward Score online, which is designed to help measure a home’s health factor via questions about a home’s insulation, fresh air supply, and moisture issues. The Well Building Standard, which has been around since 2014, also serves as an educational touchstone for builders and developers who want to learn more about the health of a house and the air inside.
