Abstract
This paper addresses the estimation of a residential building’s embodied energy through real-time data and evaluates the influence of diverse infill wall materials on its embodied energy. The investigation centers on a 10storey residential structure situated in Roorkee, India’s composite climate. The study encompasses initial embodied energy from the bill of quantities and recurring embodied energy from maintenance and replacement cycles. Calculated at 11630 MJ/m², the determined lifetime embodied energy comprises 98.6% initial and 1.4% recurrent energy. A comparative analysis is conducted against existing literature and extended to alternative building envelopes. Findings indicate that using fly ash lime brick for infill walls minimizes embodied energy, potentially saving around 515MJ/m² across the building’s lifespan. This research provides valuable insights into estimating and comparing the embodied energy of residential buildings and highlights the potential energy efficiency benefits of specific building envelope choices.

The three main global energy concerns of providing access to modern energy, enhancing the security of the energy supply, and minimising the impact of energy systems on the climate have an impact on both national and international energy governance. To develop solutions that address the many facets of these difficulties, however, a variety of actors and stakeholders must be included due to the complexity of the energy challenges.
Cities are responsible for more than 70% of the world’s energy consumption and 40% to 50% of its greenhouse gas emissions. Managing increasing urbanisation is a challenge, and nations must deal with the effects it will have on the environment in terms of energy and climate.
Our transition to a future with lower carbon emissions depends heavily on buildings. They are our places of residence, rest, and employment; they also account for around one-third of the world’s greenhouse gas emissions and nearly 40% of the world’s energy usage.
