The CDL Green Gallery is an extension to the Singapore Botanic Gardens Heritage Museum and showcases botanical and greening-related exhibits. From the start, all aspects of the project – from conceptualisation, design, construction, material selection and maintenance – were intended to support sustainability and environmental protection.
The gallery boasts of two eco-innovative features introduced in Singapore for the first time: the use of a prefabricated modular system for quick construction, and hempcrete, a durable plant-based material used for the external wall cladding. The latter, which is a mixture of hemp core, lime binders and water, also has very good thermal performance ideal for the air-conditioned gallery.
Other eco-friendly features at the gallery include green walls purposefully clad with butterfly-attracting plant species to encourage biodiversity, energy-efficient interior fittings, and passive and low-energy architectural designs. In addition, the project uses highly energy-efficient building systems and solar photovoltaic-clad roof panels that harvest renewable energy for the building’s operations, making the development Singapore’s first zero energy Green Gallery.
