Design and feasibility analysis of a solar PV array installation during the construction of high-rise residential buildings

Abstract

Effective energy utilization is a key parameter to meet the increasing global energy demand, and this paper proposes to install a solar PV array during the construction of a high-rise building. Electrical energy auditing is an essential tool for the planning and installation of solar PV systems. The outcome of energy auditing and the space availability are subsequently utilized for planning the sequential installation of solar PV systems in the four segments of the construction process. Several challenges in harnessing and utilizing solar energy during the construction, along with the strategic utilization of solar PV energy are presented for the benefit of building owners after the completion of the construction process. A case study (seven 200 m high rise buildings and associated facilities) is considered to validate the proposed energy-efficient construction process, and the same is compared with the conventional construction process. From the comparison, a significant reduction in the power drawn from the grid during the construction process is noticed. It has been found from the simulation results that an estimated annual energy of 7377 MWh is generated from the 3.63 MW roof-top solar PV systems. Further, a techno-economic assessment of the proposed solar PV system is drawn to bring out the financial benefits to the contractor, and the owners of the newly constructed high-rise residential buildings. Embracing sustainability in buildings with energy-efficient construction practices in large construction projects can substantially minimize the impact of environmental pollution.
