Abstract
Rapid urbanization and population increase cause significant changes in the construction sector. Just the building sector is responsible for 40% of the carbon dioxide released into the atmosphere. Using sustainable design techniques and resources may lessen the effects of climate change. The built environment's carbon footprint can be reduced by reducing embodied energy, choosing building materials that adhere to ecological design principles such as cradle to cradle, cradle to grave, design for environment (DFE), design for deconstruction (DFD), and low impact development (LID) strategies. These strategies use locally available materials and design with the cardinal rules of deconstructable, disassessment, harmless, recycling, and less environmental impacts. When evaluating the sustainability of new construction, existing buildings, and the upkeep, renovation, and replacement of existing structures, life cycle assessment, or LCA, is a crucial tool. The quantity of carbon released and the energy needed to create a structure are known as embodied energy and carbon associated with building construction. Energy needed to extract raw materials, manufacture building components, transport them to the construction site, install them, and run them is known as embodied energy. The main sustainability tactics to use are biomimicry and design in accordance with how nature acts. The built environment suffers more when fossil fuels and traditional energy methods are used. Alternatives have gained attention; buildings are now more efficient because to the integration of hybrid systems and renewable energy sources. Major energy users in buildings have been identified as lighting, heating, and cooling services. Using local natural resources, district cooling and direct heating from geothermal energy (ground coupling) provide an ecologically friendly cooling option. Furthermore, Evaporative type cooling, downdraught cooling, earth tunnel air conditioning, chilled beam systems, and other passive cooling techniques enhance the energy efficiency of the whole structure. Possible sustainable parameter solutions and an integrated energy analysis of building services in mechanical, electrical, and plumbing systems are the topics of this article.
