|Housing component||Adaptation measure||Description||Adaptation cost||Benefit|
|Roof cladding||RF. Strengthen CTB connections||Increase BMT of metal roof sheets from 0.42 to 0.48 mm, and upgrade the screw fastener from M6–11 to 14–12.||0.7%||Improve the uplift capacities of CTB connections with the mean pull-over and pull-out capacity increased by 25% and 7% respectively.|
|Window||WS. Install shutters||Cyclone-rated steel roller shutters tested for wind pressure up to 2500 Pa.||2.0%||Reduce wind pressure and the amount of wind-driven rain acting on windows as shown in Fig. 9, and hence decrease the probability of windward dominant openings.|
|WR. Higher window rating||Increase the window rating to a higher level|
(e.g. N2 to N3).
|0.4%||Increase the ultimate strength and water penetration resistance of windows according to Table 2.|
|Building interior||IW. Water resistant materials||Use water-resistant plasterboard for ceiling and internal wall finishes.||1.0%||Improve water resistance of building interior and reduce rainwater damage as shown in Fig. 10.|
