Analysis of the Cost-effective of Environmental Enhancements in Public Buildings - Focusing on WELL Building Standard vs. G-SEED Criteria -

This study explores the impact of applying the WELL Building Standard on the environmental and financial aspects of public buildings. WELL certification promotes occupant health and well-being through improved building practices, which lead to greater energy efficiency, reduced maintenance costs, increased productivity, and lower healthcare expenses, all contributing to economic benefits. WELL-certified buildings also boost occupant satisfaction, increasing space utilization, potential rental income, and offering long-term societal advantages, such as healthier living environments and improved city competitiveness. To assess profitability, a G-SEED certified public building was used as a model, and the analysis of initial remodeling costs and projected outcomes resulted in a return on investment (ROI) index ranging from 61% to 123%, indicating positive outcomes. The results suggest that future studies will likely focus on remodeling existing buildings to assess profitability further. While the upfront costs of WELL certification can be significant, the long-term benefits can generate considerable economic and social value such as lower operational costs, better occupant health, and a stronger public sector reputation.
