LIFE CYCLE ASSESSMENT OF A CONDENSING GAS BOILER AND COMPARE WITH AN AIR SOURCE HEAT PUMP IN A RESIDENTIAL BUILDING

Abstract

This study presents a comprehensive life cycle assessment (LCA) comparing the environmental impact of a Condensing Gas Boiler (CGB) and an Air Source Heat Pump (ASHP) within the context of a residential building. As the demand for sustainable and energy-efficient heating solutions rises, evaluating the environmental performance of these technologies becomes crucial for informed decision-making. The assessment encompasses the entire life cycle of both heating systems, including raw materials, production, transportation, installation, operation, and with deep focus on end-of-life disposal through recycling, landfill, and incineration. The environmental indicators considered in the analysis include greenhouse gas emissions, energy consumption, and other relevant impact categories. This study has been conducted using SimaPro 9.4.0 program database with IMPACT 2002+ method and findings from this research aim to guide homeowners, policymakers, and industry stakeholders in making informed decisions regarding the adoption of heating technologies in residential buildings. By shedding light on the environmental implications of CGBs and ASHPs, this LCA contributes valuable insights toward the transition to sustainable and energy-efficient residential heating solutions and destruction methodologies for better environmental gain.
