Sustainable Building Materials Adoptable in Saudi Arabia
Depending upon projectspecific goals, an assessment of green materials may involve an evaluation of one or more of the following criteria: resource efficiency, indoor air quality, energy efficiency, water conservation, and affordability.
Many rigorous assessments show that the overall cost of these projects is no more than that of any equivalent conventional project. Increases in first cost are reported within the range from five-ten per cent. During the construction phase the use of the green strategies, such as downsizing of costly mechanical, electrical and structural systems can increase the saving in initial costs, while during the first two decades the increases due to the use of green technologies will result in a savings of at least ten times the initial investment in operation costs for utilities such as electricity. In rental properties, owners are concerned only with the initial cost, especially in the cases where tenants are paying the bills.
The high growth of the sector, coupled with rapid construction which overlooks energy efficiency and only focuses on initial investment, has cultivated a construction sector that constructs unsustainable homes which have deficient or no insulation, leaking windows, inefficient cooling systems and poor construction techniques. Furthermore, policy incentives currently do not exist for owners/property developers to develop sustainable buildings. Policy incentives can motivate developers into investing in sustainable technologies such as renewable energy. Unfortunately, lack of incentives results in a challenging situation for developing sustainable buildings and currently is a barrier to sustainable development.
In summary, it is better to construct the concrete houses in Saudi Arabia rather than the wooden houses.
