Singapore Leads the Way in Greening Existing Buildings
In October 2009, Singapore’s Building and Construction Authority (BCA) opened of the Zero Energy Building (ZEB) located on BCA’s Waddell Road campus. Formerly a workshop, the renovated 4,500-square-meter (48,438-sq. ft.) structure now houses corporate offices and academic classrooms and is a true zero net energy building. Jerry visited this building in 2010 and saw first-hand not only the measures taken to reduce energy use, but the continuous readout of energy supply/demand in the main lobby, making this one of the more transparently ZEB’s in the world.
An agency under the Singapore Government’s Ministry of National Development, BCA is tasked with developing green technologies to meet the goal of making 80 percent of all Singapore’s buildings green by 2030. ZEB is BCA’s flagship project and the first net-zero energy building in Singapore.
ZEB was conceived with two primary objectives:
- To serve as a laboratory for the integration of green building technologies in existing buildings.
- To be a hub for the study of energy efficiency and green buildings.
The technologies currently being testing at ZEB will have potential applications for many of the existing buildings that will be retrofitted over the next two decades to meet the national goal.
Strategically placed photovoltaic panels serve the dual purposes of energy generation and sun shading.
