### Measurement Campaign  
Modelling and calibration requested a monitoring campaign to measure both outdoor and indoor climate data. Outdoor measurements were carried out in order to use more representative climate data within the simulations. A portable measuring station was used.  
The station consisted of a copper anemometer (7911, Davis Instrument, Hayward, CA USA) with a wind speed range of 0.5-89 m/s and an accuracy of \(\pm\)1 m/s for speed and \(\pm\)7\({}^{\circ}\) for wind direction, a silicon solarimeter with a photodiode (SP Series Apogee Instruments) with a range of 0-350 mV and a sensitivity of 0.20 mV per Wm\({}^{-2}\) and a thermo-hygrometer with an anti-radiation screen (Hygroclip2, Rotronic, Bassersdorf, Switzerland) with an accuracy of \(\pm\)0.1 \({}^{\circ}\)C for temperature and \(\pm\)0.8% for relative humidity. The same portable measuring system also provided an indoor station equipped with a thermo-hygrometer (Hygroclip2, Rotronic, Bassersdorf, Switzerland) with an accuracy of \(\pm\)0.1 \({}^{\circ}\)C for temperature and \(\pm\)0.8% for relative humidity, for indoor climate measurements. A control data logger (CR1000, Campbell Scientific, Logan, UT, USA), with 2 MB flash processor for the operating system, 4 MB SRAM, program memory and data memory, 16 analogic single-ended input, 100 Hz

scan speed, \(\pm 0.06\%\) of accuracy for analogic, was used to acquire both outdoor and indoor data at a one minute time rate. To obtain a larger spectrum of information about the building conditions, three measurement campaigns were carried out at different periods of the year and in different rooms. Outdoor air temperature, relative humidity, horizontal irradiance and indoor air temperature were collected in each survey (Figure 4). During the first period--Measurement Survey A (21-26 June 2015)--the outdoor station was on top of the building's roof and the indoor station in a room of the first floor with northwest exposure. Figure 4 presents the environmental data recorded during the test period (Figure 4a).  
In the second survey--Measurement Survey B (28 July-1 August 2015)--outdoor measurements were taken from a balcony on the first floor since it was not possible to reach the rooftop with the available cabling of the outdoor instruments connected with the indoor station that was located in a room in the basement with southeast exposure (Figure 4b).  
For the third period--Measurement Survey C (13-18 December 2015)--again, due to logistic problems, only the indoor station was used. E.U.R district weather data, considered representative of

the building's surrounding environment were considered for outdoor data. The indoor measurement was taken in a room on the first floor with west exposure (Figure 4c).  
During the three monitoring periods, the indoor measuring station was located in the centre of the reference room, far from walls, openings and direct heat sources (natural and artificial light, active equipment and plants), at a height of 1.5 m from the floor.
