Implementation of Vegetated Green Urban Infrastructure: Is It Cost-Effective?
The continual increase of surrounding temperature has caused increased in energy demand for cooling. Aside from Singapore and Brunei, Malaysia also has the most electricity consumers surrounded by ASEAN countries. In Malaysia, the average annual energy growth rate for building sector has recorded an increment at 3–12% from year 1995 to 2015. Henceforth, to address this alarming energy issue, vegetated-based urban infrastructure, namely, green roof and green wall, have been introduced as innovative environmental urban development approaches. The finding shows that the value of energy saving in the building with green wall is MYR3.00 per square foot; meanwhile the maintenance cost is MYR2.70 per square foot. It could be seen that the ratio of cost-benefit analysis of green wall between annual energy saving and maintenance cost is 1:1.1. Overall, the benefit of green wall is higher than cost of green wall by using cost-benefit analysis. On the other hand, green roof could save the energy in between 37% and 40% for units positioned exactly below green roof area, approximately. Nevertheless, maintenance cost is 31–40% higher than energy saving. The average ratio of cost-benefits between maintenance expenditure and energy saving is 1.5:1. This study has empirically proved that maintenance cost of green roof outweighs the benefits of energy saving. This study contributes significantly to Malaysia green building valuation facet and assists stakeholder to make decision on green roof investment.
