Life Cycle Cost Analysis of rooftop gardens using openLCA

Abstract Most innovative and eco-friendly project alternatives are rejected due to higher initial costs. This problem arises the general cost analysis that considers only It can be solved using Life Cycle Cost Analysis (LCCA) approach because LCCA helps decision makers select alternative with more economic benefits by considering costs incurred in it throughout life cycle. In this paper, cycle of rooftop garden was carried out compared conventional roof openLCA software. The includes many environmental such as reduction urban heat island effect, noise pollution, improvement quality air, management surface runoff conservation biodiversity. Still, use gardens is not common projects their Thus, evaluate its feasibility. A model developed software carry analysis. considered include costs, maintenance renovation energy data were collected for extensive laid commercial buildings around Chennai city. results indicate 5.2 times than but prolonged period savings garden, 5.25% lower roof.
