Life cycle environmental assessment of an office and residential building in Northern India

Abstract

Now a day’s every one using the passwords for user authentication Structures require utmost effectiveness and strength in their entire life cycle apt from its development to obliteration. To recognize the specific predominant phases of most prevalent and huge energy consumption to establish stratagems for its decline a study is essential on every usage of the energy throughout its life cycle. This project purposes to signify the environmental hazards of a residential and an educational construction positioned in the state of Uttar Pradesh, India. Life cycle assessment has been used to determine which life cycle phase (construction, operation, maintenance, and demolition) contributes the most to the total impacts. It has been found that operational phase alone adds more than 80% to GHG emissions and is topmost energy consumer. Around 90% of total life cycle energy is consumed by residential building and 88% of total life cycle energy is consumed by an educational building in their anticipated reliability in terms of 50 years of service life. This scholastic work also projects that RCC framework and Red brick masonry are the greatest contributors in GHG radiant emissions for both the buildings. Energy consumed in the construction phase is the second highest that contributes significantly. The results obtained from this study has been compared with other studies done on similar basis, it is found that a building being situated in a region where climatic conditions vary greatly the operational energy accounts for more as compared to the buildings situated in places where climatic conditions are generally constant keeping this in mind there is a demand for some substitute to design buildings for sustainablility.
