The construction sector offers numerous advantages to the world. Some of which include the provision of buildings, streets, tunnels etc. The change in climate is one of the many challenges in this dispensation which requires that techniques and strategies should be developed for the purpose of efficient energy supply. This brings into light the need to design methods for the calculation of energy use in buildings. A few empirical research has been conducted concerning the study of the causal links between urban growth and the consumption of electricity in the specific case of Ghana. It has been found out that the insulation of walls and ceiling has the tendency to reduce building energy consumption by 70-80% and 65% respectively, as compared to a building of the same type and material but without insulation. The climatic condition of Ghana is such that the south-western part is hot and humid and the northern part experiences a hot and dry climate and has a warm eastern coastal belt. In simple term, Ghana is a hot temperate zone. Nonetheless, the climate varies with time. It is therefore paramount to introduce building insulators to reduce the energy requirement of the buildings especially in the residential sector of the country. This paper will therefore consider the introduction of thermal insulation on building façade in Ghana and the mathematical model to achieving optimum thickness suitable for a particular region or city. The mathematical model for determining the threshold values for CDD and HDD is also considered.
