Abstract
Although there have been many past studies done on the impact of embodied energy (EE) and embodied carbon (EC) of walling materials on the total life cycle energy and emissions of the building, this research focused mainly on identifying the significance of EE and EC of three types of walling materials commonly used in Sri Lanka with respect to their initial and maintenance costs. A mixed research approach consisting of semi-structured interviews and a case study was adopted to study the three types of walling materials: conventional bricks, cement blocks and eco-interlocking bricks. A questionnaire was also distributed among 60 households. The three walling materials were ranked based on their initial/maintenance costs and whole life EE and EC. The eco-interlocking brick was ranked first, cement block second and conventional brick third. A methodology was also developed to identify the walling material most suitable for Sri Lanka, by analyzing the initial/maintenance costs and whole life EE and EC of different walling materials available in the country.

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
