(Choose 2) A Life Cycle Cost concentrates on economics B Life Cycle Assessment concentrates on the environment and people C Life Cycle Cost concentrates on the environment, people and economics D Life Cycle Assessment concentrates economics 38of39 S T U D I O 4 Life Cycle Cost =LCC =Economics Life Cycle Assessment =LCA =Environment and People Life Cycle Cost (LCC) analysis is a method for assessing the total cost of ownership. It takes into account all costs of acquiring, owning and operating, and the eventual disposal of a building. Sustainable design requires an analysis of a building over its entire life and life cycle cost analysis identifies which high performance building systems will save money over the life of the building. For example: Product A may cost less and have a life expectancy of 5 years whereas Product B may cost a little more but have a life expectancy of 15 years, making Product B a better choice due to it having a better life cycle cost. All of the building expenses that can be calculated are included in the analysis: Initial costs (design and construction) Operating costs (energy, water, other utilities and personnel) Maintenance, repair and replacement costs Salvage value at the end of the buildings life Life Cycle Assessment (LCA) is an informed choice of building materials and systems that minimizes the negative impacts of the building and land use on people and the environment. The process begins as early as planning and design, analyzes construction activities and then goes beyond convention by including building operations and the eventual retirement and renewal of materials. In essence, a life cycle assessment considers the building along with its materials and components, from their extraction, manufacture and transport, to their use, reuse, recycling and disposal.
