Buildings XI Conference -- Indoor Hygrothermal Conditions in Multifamily Dwellings—Measurements and Analysis ✓ Most Recent

In order to design a building envelope that provides for a healthy indoor climate and sustainability, both energy and moisture simulations are needed. Decisions during the building process often are based on results from simulations of energy and moisture. Accurate simulations call for comprehensive input data regarding indoor temperature and indoor moisture supply. Simulations for residential buildings lack the necessary data, a deficit that must be resolved over time in a way that allows both short and long term variations to be described. As a part of an ongoing study, these parameters were measured in 18 apartment buildings containing 325 apartments in total. The parameters were measured at the building level through measurements in the exhaust air of the ventilation system, which provided average values for the apartments. Measurements of the outdoor temperature and relative humidity enabled calculations of moisture supply, which is defined as the difference between indoor vapor content and outdoor vapor content. The parameters were monitored every 30 minutes for one year. The buildings were located in Sweden between latitude N56° and N67°. Examples of results are data on averages, distributions between houses, and variations and spans during the day, during the week, and throughout the year. The presented data can help to improve simulations of indoor climate and energy use in residential buildings, which will make building envelope design decisions more appropriate. See more
