Greening Existing Garment Buildings: A Case of Sri Lanka
Green retrofitting is the justifiable solution for contemporary issues such as global warming, resource depletion, and greenhouse gas emissions which have arisen due to the existing conventionally built environment. Nevertheless, the building owners are less willing to invest in green retrofits due to the contradictory views associated with the first cost and payback period implications of the green retrofit. In that context, this chapter presents an assessment of the first costs and life-cycle saving implications of fourteen (14) energy and water-efficient retrofits incorporated into four (04) garment buildings in Sri Lanka to find the retrofit options which are financially sound. The green retrofits such as skylights, LED lights, steam line insulation, compressed airline modification, biomass boiler, evaporative cooler, energy-efficient chiller, and VSDs were implemented in the garment buildings in Sri Lanka as energy and IEQ measures. Additionally, the selected buildings were upgraded using green retrofits such as subsystem-level water meters and low water flow push taps. All the selected green retrofits are financially practical with positive NPVs and SPB periods of less than 5 years. This information would provide some cost-based considerations for green investors in the selection of retrofits for other industrial buildings and thereby contribute to promoting sustainable developments.
