As to energy, the primary goal was to achieve the Leadership in Energy and Environmental Design (LEED) Zero Energy as well as the International Living Future Institute's (ILFI) Living Building Challenge (LBC) certifications, exceeding a net-positive energy threshold of 5% based on proven performance during a 12-month period. A few months after the building began its operation in late 2019, the COVID-19 pandemic hit, altering building operations and disrupting the planned course for certification. A calibrated model based on postoccupancy data of the building's energy and water performance was created and used to support the claim that the Kendeda Building would still have been sufficiently net-positive for energy if the performance year went under two different scenarios: a hypothetical business as usual" year without the pandemic and a full-year of extreme-load operation. For these two scenarios the Kendeda Building was found to be able to certify with 125% and 38% net-positive energy respectively." Pages: 414 - 423 Paper:simbuild2022_C047
