Abstract.

The purpose of this research was to determine comfortable ranges and limits of temperature and relative humidity on the Psychrometric Chart that will reduce energy use and encourage human adaptation by developing tools that identify appropriate strategies within the selected agro-ecological zones. The objectives of the research were to develop a more accurate bioclimatic chart for the selected climates and to determine the range and limit of the harmattan using Arduino controlled Drone. The analysis was performed with the Psychrometric Analysis Suite, MATLAB and TMY2 weather data captured by the Arduino controlled Drone and data from the Ghana Meteorological Services Department for the selected climates - Accra, Kumasi and Tamale. To achieve these objectives, two main tasks were accomplished: namely: Analysis and modification of comfort strategy and boundaries using the ASHRAE programme and TMY2 weather data to simulate the range and limits of temperature and relative humidity and to develop general guidelines for the new bioclimatic chart for deeper understanding and appreciation of the data in relation to human comfort. The solar radiation recorded by the drone with models estimated gave the lowest insolation range (between 21 MJm−2day−1 and 8.4 MJm−2 day−1) for the forest agro-ecological zone of Ghana.
