Mangkuto, R A and Paramita, B (2022) Computation of the greenery-sky-view factor in daylit buildings. Architectural Engineering and Design Management, 18(6), pp. 850-869. ISSN 1745-2007
Abstract
The greenery-view factor has been recently proposed as a new, simple measure to assess the possibility of having visual access to view the outdoor greenery in a daylit building space, based on the constructed lines of sight. However, detailed expressions to compute the factor is yet to be provided, and correlations with the input variables are yet to be determined. This study aims to address those issues, by combining the 'no-greenery line' with the 'no-sky line' to create the greenery-sky-view factor (GSVF), which is the fraction of the floor area, at the eye-level height, from which the greenery and the sky are visible. Mathematical expressions to compute the GSVF are described for various scenarios involving the window-to-wall ratio, the elevation of the greenery, and the distance between the window and the greenery. Computations of 10,000 random combinations are performed to find the optimum input variables leading to the largest GSVF and to determine correlations between the input and output. Recommendations for design practice are provided based on the computation results.

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
