Achieving Energy Efficiency through Retrofitting of Building Envelope: The Case of a Hospital in Meerut, India
Journal: Architecture Engineering and Science DOI: 10.32629/aes.v6i3.4355
Abstract
In order to reduce operating costs, lessen the impact on the environment, and guarantee a sustainable healthcare infrastructure, hospital facilities must practice energy saving. Carbon dioxide emissions have a major impact on the environment and contribute significantly to worries about global warming. In order to give the best possible thermal comfort, a significant amount of energy is used in hospital buildings for lighting, ventilation, heating, and cooling. For these constructions, energy conservation is crucial. Insulating exterior walls is a common way to boost a building's energy efficiency. This is a tried-and-true method given the ongoing rise in energy prices worldwide and the commitment to furthering global climate initiatives. Healthcare institutions must undergo energy retrofits in order to reduce energy use and improve sustainability. For this, a variety of materials can be used, each with unique benefits and challenges. The feasibility of several materials, including roofing, window glazing, and insulation, for energy retrofitting in healthcare buildings is investigated in this article. This paper describes how to use sustainable materials, including polyurethane spray and composite panels (ETICS) for thermal insulation on the roof and external walls, to increase energy efficiency in healthcare buildings, namely the Nutema multispecialty hospital in Meerut, India. Using Rhino 7 and Climate Studio software, the present building's Energy Performance Index is evaluated. Analysis and comparison have been done on a number of examples. Energy-efficient roof and wall insulation can be achieved during retrofitting by using sustainable materials like polyurethane spray, external thermal insulation composite panels (ETICS), and double-glazed windows.
