    Energy conservation and optimization of HVAC design in-line with USGBC codes
    (UMT, Lahore, 2020) ARSLAN FAISAL
    With the rapid growth in global population and continuous improvement in the quality of life style, the energy consumption is at rise causing an increase in fossil combustion and ultimately pollution. Therefore, efforts are being made to optimize energy consuming systems for power utilization. In large buildings, small electrical air conditioners are not used due to their high power consumption and short running life, but preference is given to the central air conditioning for being more economical due to its lower maintenance cost and being energy efficient. Therefore, in large buildings such as auditorium, educational and commercial buildings, central air conditioning systems are used. The precise calculation of cooling load is needed to reduce capital cost and power consumption, and to maintain a comfortable environment in a building. This research work presents cooling load calculation for a building in the University of Management and Technology (UMT), Lahore, Pakistan for peak running time using cooling load temperature difference (CLTD) method. Sensible cooling load calculation for vapor compression system using CLTD method is presented to replace the existing high-power consumption cooling system, partially or completely, with an energy efficient system for maintaining human comfort without effecting indoor air quality (IAQ). The heat gains due to structure, lighting, occupancy, and equipment were simulated using Carrier's Hourly Analysis Program (HAP). The analysis of Green Building Design showed significant improvement compared with the existing building design. The analysis of a building’s HVAC design is carried out to highlight the benefits of achieving LEED standard in the UMT building.
