Abstract: The thermal performance of buildings with a high percentage of glass is essential in the harsh weather of Kuwait for buildings with historical importance. The Municipality Complex of Kuwait has historical and symbolic significance due to its double-skin facade (DSF) that represents modernity and democracy during the 60s of the last century. Such an essential environmental feature has not been maintained and utilized correctly. Besides, the recently implemented high electric tariffs dictate urgent energy savings solutions to the 60-year-old Complex. In this thesis, analysis and diagnosis of the thermal and indoor environmental quality are carried out using qualitative and quantitative methods. Several site visits and investigation of Complex’s blueprints gives an overall idea of occupants’ perception and complete building indices. Then an extensive questionnaire distributed randomly to 321 occupants to analyze their thermal and indoor air environment (IAE) satisfaction, along with five other categories that include general and historical importance of the Complex. Furthermore, monitoring of measurable environmental factors (MEF) for six chosen different spaces is performed for two years on an hourly basis. In particular, dry bulb (DB) temperature and relative humidity (RH) readings using HOBOs are monitored, analyzed, and validated to figure out the thermal environment quantitatively. Such readings are plotted on psychometric charts with the ASHRAE comfort zone. On top of that, the questionnaire is repeated and given to the occupants of the six monitored rooms for further validation and comparison. It is found that the envelope’s curtain wall is very loose and causes excessive infiltration rates with high levels of humid air. It is also detected that the removal of the interior skin of the DSF increases the solar radiative effect, which causes excessive overheating, energy wastage, and occupants’ thermal dissatisfaction. In addition, it is discovered that chillers’ operate at high capacity during the humid months due to the high infiltration of humid air. Moreover, it is found that thermostatic set-points remain the same during unoccupied hours. It is highly recommended to retrofit the curtain wall with higher-performance glazing. Also, it is recommended to use interior plants in the gap to create better IAE and to improve shading as well. Further, HVAC retrofit with the use of variable frequency drive (VFD) and energy management system (EMS) for thermostat setup temperatures during an unoccupied period must be installed in the future rehabilitation of the Complex.
