EVALUATION OF THE INDOOR AIR QUALITY AND ELETRICAL ENERGY CONSUMPTION IN THE 200 HOUSING UNIT ESTATE, LOKOJA, KOGI STATE

Abstract

ABSTRACT Indoor air quality is one of the most significant factors affecting the health and well-being of occupants. The assessment of the overall comfort of the environment places foremost attention to human health. The study aimed at Evaluation of Indoor Air Quality and Electrical Energy Consumption of the residential building in 200 housing unit estate Lokoja, Nigeria, following the ASHRAE standard guide, with a view to ascertain the current level of indoor air parameter with relation to energy consumption. The study employs the use of experimental reading, using air visual and electrical energy monitoring device in determine indoor air parameter such as temperature, particulate matter PM2.5 CO2, relative humidity, temperature and setting the device at 2hr interval, 1m away from the walls of the building for 24hrs per day. Descriptive and inferential statistics were used for analyzing the acquire mean with SPSS file, Pearson’s correlation was used to determine the relationship between indoor air quality and electrical energy consumption. Findings revealed that the CO2, PM2.5 and relative humidity are within the set’s standard of ASHARF, but temperature exist set limit of the study area. Furthermore, correlation relationship between the average operative IAQ and the average energy consumption is perfectly negative where the Pearson’s correlation coefficient, r, is equal to -0.126 (p-value < 0.01) which indicates moderate and significant correlation. Therefore, the study recommends the use of HVAC, Fan Force Ventilation, dehumidification and further study on indoor air quality and electrical energy consumption.
