Evaluating building design options with a focus on simultaneously minimising life cycle greenhouse gas emissions (GHG) and life cycle cost (LCC) is difficult due to a lack of comprehensive and accessible tools. An integrated approach where life cycle GHG and LCC performance can be balanced is essential in order to optimise a building's overall life cycle performance.
There is growing concern about the effect that buildings are having on the environment. Mitigation strategies tend to focus on one life cycle stage, usually the operational stage, leaving the other life cycle stages, such as manufacturing and construction, largely ignored. The slow uptake of whole life cycle design is further hindered by the uncertainties associated with the economic implications of life cycle environmental optimisation.
