Building envelope:The main characteristics of the building envelope are presented in Table 1. The U-values of the external walls and the flat roof have better insulation values than nationallegislation requirements.• external walls 0.2 – 0.3 W/ m² K• flat roof 0.12 W/ m² KMain window specifications are summarized in the table below.Tabelle 55: window specificationsFrame Glass SHGCUf Ug gW/m²K W/m²K -Offices 1.4 1.1 0.5Public Help Desks 2.2 1.1 0.379.5.4 Experimental and computational investigationsHourly measurements were carried out for 1 year (2009) and are still ongoing. Energyconsumption for space heating, ventilation, hot water, electricity, lighting, andequipment is metered separately. Additionally, occupancy was carefully monitored byinterviewing employees, and all details noted for reproduction in the simulation. Thetechnical equipment in each room was also documented with partial metering ofequipment electricity consumption.Measured values were simulated by modeling the entire building in the“BuildOpt_VIE” software developed at the Research Centre of Building Physics andSound Protection, Vienna University of Technology. This program was validated usingdata from Annex 41.221
