| Summary: | Air-conditioning and mechanical ventilation system (ACMV) is one of the main contributors to the total building energy consumption.According to previous works,buildings use about 60% on air-conditioning of the total energy consumption.At the same time,the most economical way was to determine the most efficient system for air conditioning system.Temperature,humidity,pressure and air motion are some of the important variables that refrigeration and air conditioning deals with the techniques to control the environment and provide comforts to enable the better living.Factors that affect
human comfort were determined by using Indoor Air Quality Meters and also by calculating the building energy index for 2016 and 2017.From the study,measurement and evaluation of the existing indoor comfort parameters of the Laman Hikmah Library building located in the Universiti Teknikal Malaysia Me/aka (UTeM) main campus were conducted.The area of the library building is 10,063 .68 square meters that covers of four floors.The physical parameters such as air velocity,average flow,average operating temperature,average relative humidity,lighting, and C02 readings were recorded,analysed and then compared to the current ASHRAE-55 and MS1525:2014 standards.Based on the collected data and information,the total building cooling load is then being estimated.In addition,the Building Energy Index could also be detennined,where it was found that the results were 94.4252 kWh/m2/year and 117.8952 kWh/m2/year for the years 2016 and 2017 respectively.All of these values were less than the MS 1525:2014 Standard of 135 kWh/m2/year.The current energy consumption for all floors that the air conditioning
recorded the highest rate consumption was 67.75% of electricity usage in building,followed by the consumption of lighting was found to be 17% and others equipment 15.25%.Finally,economic analysis is included with potential alternative measures to achieve optimum building energy usage. |
