To solve today’s supply chain challenges, should we ignore the building energy code? No, accepting less today in return for higher costs tomorrow is no strategy at all.
The inconvenient truth for critics of building energy codes is that compliance with current versions of the IECC and ASHRAE 90.1 serves as the most cost-effective mechanism for reducing building energy use and the associated carbon emissions generated from powering schools, office buildings and other commercial spaces. While today’s supply chain challenges are certainly frustrating, ignoring the energy code eliminates long-term improvements in building energy efficiency and saddles building owners with higher energy costs for decades to come.
Energy codes provide minimum standards for new and existing buildings. One way the codes help improve the performance of existing buildings is by requiring that roof replacement projects comply with code minimums for building envelope insulation. A recent study by PIMA and the consulting firm ICF International confirmed that energy code-compliant roof replacements are life-cycle economical under various conditions even when subjected to higher incremental installation costs and discount rates. For example, a primary school located in Climate Zone 5 (Chicago) can experience an estimated 9% savings in annual whole building energy use by installing a roof replacement with code-compliant levels of insulation. These savings will continue to compound year-over-year during the roof’s service life.
Simple, short-term solutions can be appealing in times of duress. In the case of building energy efficiency improvements, a short-term focus that sacrifices long-terms benefits is a bad deal for building owners.
