Table 6 Climate adaptation measures for contemporary housing

From: Risk-based cost-benefit analysis of climate adaptation measures for Australian contemporary houses under extreme winds

Housing componentAdaptation measureDescriptionAdaptation costBenefit
Roof claddingRF. Strengthen CTB connectionsIncrease 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.
WindowWS. Install shuttersCyclone-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 ratingIncrease 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 interiorIW. Water resistant materialsUse 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.
