|---|---|
| Scope | One 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. |
| Caveat | Single 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. |
