As the thermal insulation performance of buildings improves, the energy loss due to infiltration in buildings is gradually increasing. The infiltration rate in buildings varies depending on the indoor and outdoor temperatures differences, outdoor wind speed and direction. Recently, retrofitting for energy performance improvement of existing buildings has been widely conducted in South Korea as well. The energy savings of retrofitting an existing building are evaluated through an energy performance assessment before and after the retrofit. While there is abundant data available regarding the thermal insulation performance of buildings for existing buildings, there is a lack of data concerning the airtightness performance, which significantly influences building energy performance.
The aims of this study is to compile airtightness performance data for small-scale childcare centers, which are currently undergoing retrofitting extensively in South Korea, through actual measurements. The measurement of infiltration performance was conducted using the CO₂ decay method, with CO₂ emitted by occupants being utilized. A total of 76 childcare-centers located in Gyeonggi Province were measured utilizing NDIR (Non-Dispersive Infrared) CO₂ sensors. Also, building physical performance were identified through drawings and on-site measurements, and the external environmental conditions were obtained from meteorological data provided by the Korea Meteorological Administration.
As a result, airtightness performance data for existing childcare centers has been compiled. This data, measured under actual indoor and outdoor environmental conditions, will be utilized for evaluations of the building's physical and energy performance, among other aspects.
