This study analysed the current thermal comfort conditions of Balikesir University Hospital in Turkey. Measurements and questionnaire surveys were performed to evaluate thermal comfort conditions. Environmental parameters such as air temperature, globe temperature, relative humidity and air velocity were measured. A total of 429 questionnaires were collected and analysed by using SPSS software version 22.0 to understand patients’, visitors’ and nurses’ perceptions on thermal comfort in the hospital. A total of 214 surveys were conducted in the summer period, and 215 surveys were conducted in the winter period. According to the results, thermal comfort levels for each group were ‘neutral’ in summer and ‘slightly warm’ in winter. Barely, the survey results showed that perception of thermal comfort was ‘slightly warm’ in summer and ‘neutral’ in winter. The thermal comfort level was mostly affected by differences in gender, age, participant type and orientation of the room. Furthermore, the requirements set out in standards did not meet those of respondents’ perceived thermal comfort. Finally, the relationships between predicted mean vote, actual mean vote and operative temperatures were examined. This analysis also demonstrated that the preferred temperature was 2·5°C below the predicted temperature for summer and 1°C above the predicted temperature for winter. According to these results, the neutrality point has shifted to +0·7 on the seven-point scale for both seasons.

There are power plants that use different fuels and technologies to produce electricity that is consumed to cool the buildings in the summer period. These power plants emit Gases Harmful to the Environment and Human (GHEH) such as carbon dioxide (CO2), sulfur dioxide (SO2), nitrogen oxides (NOx) and particulate matter (PM) as a result of the combustion of the fuels they use while producing electricity. In the study, the number of emissions to be released from the power plants that produce the electricity used for the cooling of the buildings was examined. Emission reduction due to carbon capture and storage system (CCS), which is one of the new technologies that reduce the released emissions, has been investigated. The use of CCS and the emissions from its use are compared. A long-term Life cycle emission assessment has been made. The annual amount of electrical energy in the buildings was determined according to the cooling degree-day method. In the coal-burning systems of Turkey (CCS), 0.187-0.120 kg/m2 CO2, 0.00040-0.00026 kg/m2 SO2, 0.000322-0.000206 kg/m2 NOx, 0.000014-0.000009 kg/m2 PM emissions have been determined. In natural gas burning systems using CCS, 0.090-0.058 kg/m2 CO2, 0.0000018-0.000012 kg/m2 SO2, 0.000527-0.000337 kg/m2 NOx, 0.000002-0.000001 kg PM emissions were determined.
