Water-side economizing energy saving, heat-source system (chillers, cooling towers, pumps), one Suwon laboratory building

52.8% modeled for Jan–Mar and Nov–Dec; 42.0% measured in a separate 42-day trialmodeled

Value kindmodeled — Interpret this value according to its displayed kind, scope, source, and as-of date.
ScopeOne laboratory building in Suwon, Korea. The 52.8% is a simulation of the five economizer months (January to March, November and December), averaged over five weather years: 574.1 MWh without economizing against 270.8 MWh with it. The 42.0% is a measurement over 28 December 2023 to 8 February 2024 against the same period a year earlier. The boundary is the heat-source system: chillers, cooling towers and pumps. Neither number is a full-year saving.
CaveatSingle non-data-center building, and no full-year figure: the other months' baseline energy is not given. ENERGY STAR's 'up to 70%' applies only to hours when the economizer runs.
