Test cell data-based predictive modelling to determine HVAC energy consumption for three façade solutions in Madrid. Informes de la Construcción, 69(548) ABSTRACTThis study aims to narrow the gap between predicted and actual energy performance in buildings. Predictive models were established that relate the electric consumption by HVAC systems to maintain certain indoor environmental conditions in variable weather to the type of façade. The models were developed using data gathered from test cells with adiabatic envelopes on all but the façade to be tested. Three façade types were studied. The first, the standard solution, consisted in a double wythe brick wall with an intermediate air space, the configuration most commonly deployed in multi-family dwellings built in Spain between 1940 and 1980 (prior to the enactment of the first building codes that limited overall energy demand in buildings). The other two were retrofits frequently found in such buildings: ventilated façades and ETICS (external thermal insulation composite systems). Two predictive models were designed for each type of façade, one for summer and the other for winter. The linear regression equations and the main statistical parameters are reported. Keywords

Evaluation of Thermal Comfort Conditions in Retrofitted Facades Using Test Cells and Considering Overheating Scenarios in a Mediterranean Climate

“…The use of on-site testing to assess real performance, using scale models [32] or real-scale test cells, is considered the best option. Test cells allow different elements of the thermal envelope to be evaluated [33], providing reliable results in real outdoor conditions, with a level of instrumentation that guarantees more accurate results than those of in-use monitoring [34].…”
