Abstract
Purpose: The purpose of this study is to describe life cycle cost (LCC) and life cycle assessment (LCA) evaluation for single story building house in Malaysia. Two objective functions, namely, LCA and LCC, were evaluated for each design and a total of 20 alternatives were analyzed. Two wall schemes that have been adopted from two different recent studies toward mitigation of climate change require clarification in both life cycle objectives. Design/methodology/approach: For this strategic life cycle assessment, Simapro 8.3 tool has been chosen over a 50-year life span. LCC analysis was also used to determine not only the most energy-efficient strategy, but also the most economically feasible one. A present value (PV)-based economic analysis takes LCC into account. Findings: The results will appear in present value and LC carbon footprint saving, both individually and in combination with each other. Result of life cycle management shows that timber wall−wooden post and beam covered by steel stud (W5) and wood truss with concrete roof tiles (R1) released less carbon emission to atmosphere and have lower life cycle cost over their life span. W5R1 releases 35 per cent less CO2 emission than the second best choice and costs 25 per cent less. Originality/value: The indicator assessed was global warming, and as the focus was on GHG emissions, the focus of this study was mainly in the context of Malaysian construction, although the principles apply universally. The result would support the adoption of sustainable building for building sector.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
