ASHRAE releases expanded, revised version of Standard 90.1
Standard 90.1 has been a dominating benchmark for energy codes in the commercial building space since 1975, but recently a large update to this benchmark has been released that brings about important changes for all relevant industries to be aware of. ASHRAE released a revised and much-expanded version in and for 2019 and includes changes regarding lighting, mechanical, budget method, and performance rating methods, to name a few. On the mechanical side, for one example, the revised version allows designers the option to use 90.4 instead of 90.1 for rooms with IT equipment load larger than 10kW.
It is highly encouraged for all professionals in relevant industries to be familiar with this expanded and revised version of a Standard that has such a wide footprint over many different industries.
