The gap being that there are just in a few number of researches that relate to flood resistance. In addition, heat and flood properties of present material products cannot coped with future climate. Qualitative developing envelope house all of three parts. Wall materials should develop heat resistance to medium laver which is U-value is 1.3-1.55 W/m2k, R-Value is 0.64-0.77 m2k/W and K-Value is 0.13-0.155 W/mK and flood resistant wall materials value should be at a high level these are: less than or equal to 0.5% of water absorption, less than or equal to 1.5% of water penetration and less than or equal to 6% of swelling test. Second, roof materials should develop heat resistance to a high level which is U-value being greater than 0.43 W/m2k, R-Value greater than 2.32 m2k/W and K-Value should be less than 0.043 W/mK. Third, opportunities of developing flood resistant materials are the same as flood resistant wall materials value. Furthermore, concrete and fiber-cement products are popular materials which use should be promoted. |
