- Abstract
- Energy efficiency in buildings can be understood elaborately by evaluating its operational and embodied energy. Embodied energy is the sum of all the energy that is used to produce materials in a building construction. This study assesses various building parameters e.g. U-value of the materials, Window to Floor Area Ratio (WFR), location, etc. that affect the operational and embodied energy and understands the optimization of the trade off between the operational and the embodied carbon impacts. The study focused on simulating three different residential building layouts in three different locations of the world. The energy simulations were performed in Design Builder and the life cycle assessment calculation was performed with etool. It... (More)

The study focused on simulating three different residential building layouts in three different locations of the world. The energy simulations were performed in Design Builder and the life cycle assessment calculation was performed with etool. It is to be noted that the current study does not account for the structure of the building, material wastage, transportation of materials to the site nor the carbon required during stages of construction, demolition and subsequent re-use, recycling, or waste disposal of the materials. As, the simulations were not conducted in a detailed manner due to the various limitations of the software, hence different results could be expected based on different parameters used and the depth of the study. The results in this study indicated a better building performance in the UK compared to USA and India due to better building regulations and standards in UK focusing on creating more environment friendly and energy efficient homes. Also the higher the WFR, the higher is the GWP and the higher the operarional carbon. (Less)
- Popular Abstract
- Climate change has occurred due to shifts in climatic patterns over many years. These changes have resulted in the emission of greenhouse gases, which trap heat in the atmosphere and contribute to global warming. Addressing emissions from buildings is crucial for mitigating climate change and promoting sustainable development. Environmental concerns related to buildings encompass both operational and embodied carbon emissions. Operational carbon emissions arise from the day-to-day activities of buildings, including energy consumption for heating, cooling, and lighting, while embodied carbon emissions occur throughout a building's entire lifecycle. Improving the energy efficiency of buildings stands out as a key strategy for reducing both... (More)
- Climate change has occurred due to shifts in climatic patterns over many years. These changes have resulted in the emission of greenhouse gases, which trap heat in the atmosphere and contribute to global warming. Addressing emissions from buildings is crucial for mitigating climate change and promoting sustainable development. Environmental concerns related to buildings encompass both operational and embodied carbon emissions. Operational carbon emissions arise from the day-to-day activities of buildings, including energy consumption for heating, cooling, and lighting, while embodied carbon emissions occur throughout a building's entire lifecycle. Improving the energy efficiency of buildings stands out as a key strategy for reducing both operational and embodied emissions. Incorporating climate adaptation measures into building design further enhances resilience to the impacts of climate change, such as rising temperatures. Emphasizing sustainability, adopting green building standards, and obtaining certifications contribute to lowering the carbon footprint of buildings over their lifecycle. Prioritizing sustainable and low-carbon building practices not only diminishes environmental impact but also fosters healthier and more comfortable living environments.
This study delves into the analysis of various design parameters influencing operational and embodied energy in buildings, aiming to contribute to the advancement of sustainable building practices. (Less)
