Sengupta AJCEA2013132 10.12691/ajcea-1-3-2 2013 03 28 2013 04 23 2013 04 26 This paper is concerned with assessing the buildingĄ¯s the energy efficiency and qualities of a modular design for the education industry, in order assess the long economic benefits. The research includes a life-cycle energy and cost analysis of the school building design, predicting the impact on the operational cost of the building as a result of the addition of photovoltaic panels. The paper also includes a comparative study between the ECO Modular Solutions building, and a current standard prefabricated school building, quantifying the savings in CO₂ emissions and savings in cost.
