Abstract:
Despite the potential to reduce Energy Use
Intensity (EUI), passive design strategies (PDS) have been
sparsely integrated into residential high-rise buildings in Sri
Lanka partly due to the lack of scientific knowledge available
for the construction industry professionals. To bridge this
knowledge gap, this study presents a set of guidelines for
choosing suitable PDSs for residential high-rise buildings in Sri
Lanka. The guidelines are based on the findings of local (LSA)
and global (GSA) sensitivity analyses, which evaluated seven
popular PDSs in the Sri Lankan construction industry. LSA
revealed how EUI varied with PDSs and the most and least
reductions for low e-coating on glasses (WS) and multiple
glazing (GU). GSA ranked WS and GU as the most and least
influential PDSs and categorized the seven PDSs into three
groups based on the effect of PDS on EUI in the presence of
other PDSs. An evaluation of six PDSs: five combinations and
one individual PDS (WS) suggested the combinations should be
established between the most influential parameters in the same
group to maximize EUI saving. A significant difference in
popularity and efficiency was found for the seven PDSs, as the
most popular PDSs are the least effective in saving EUI.
