In light of current environmental trends, there is a growing stringency in energy requirements. Energy analysis encompasses various categories, including computations for fenestrations (glass) such as area, material type, and energy efficiency, as well as the overall efficiency of wall and roof types. This analysis also influences the selection of cooling and heating systems for a space or building. Regulations may mandate the installation of rooftop solar panels or green roofs to mitigate heat island effects and reduce loads on cooling/heating systems. Ultimately, these principles should be viewed as long-term investments in the building lifecycle, offering financial benefits to both occupants and owners.
