Assessment of climate change impact on the required cooling load of the hospital buildings

The impact of climate change on the energy performance of the heating,ventilation and air conditioning (hvac) systems was studied in this research. the present research employs the transient system simulation software (trnsys) to study the hour-by-hour influence of the climate change scenario on a hvac system performance by modeling the system in the trnsys software as the base line model. to this end,a hvac system operating in a hospital as a high energy demanding building was selected for data collection,analysis and simulation. three sets of predicted typical meteorological year (tmy) data for the region are used for simulation in the trnsys to analyze the established indoor air conditions and yearly required cooling loads by the building. based on the predictions and comparison of the findings with the year 2000,it can be estimated that the yearly required cooling load for 2020 and 2050 would be increased by 4.66% and 7.3%,respectively. © school of engineering,taylor’s university.
