The installation has 74 m2 composed of 56 monocrystalline Silicon Photovoltaic Glass modules with a glass configuration of 6+6 mm. All of those modules have a 12 mm air chamber which provides additional thermal and acoustic insulation, improving the comfort of visitors as well as the flora that houses this building.
These PV glass modules have a light transmittance of 60%, letting natural light in for the perfect development of their orchid plants, the country’s national flower.
The rectangular units have 15 different dimensions to perfectly adapt to the existing metal structure. Likewise, the rhomboidal and trapezoidal units have been 100% customized to the client's requirements.
The installation is located in The Sembcorp Cool House at the National Orchid Garden. The facility is one of the jewels in the crown of the new Tropical Montane Orchidetum which was opened by Prime Minister Lee Hsien Loong in April 2021.
Designed by Ramboll Studio Dreiseitl, The Sembcorp Cool House has been built to emulate a high-elevation montane forest, which exists at altitudes of between 1,000 m and 2,000 m, with a surrounding temperature of between 16ºC and 23ºC. It features the largest collection of high-elevation montane orchids in Asia.
The National Orchid Garden provides a place for 60,000 orchid plants, consisting of 1,000 species and more than 2,000 hybrids, and it is on the highest hill in the Singapore Botanic Gardens. Founded in 1859, The Singapore Botanic Gardens is one of three gardens in the world, and the only tropical garden, to be honoured as a UNESCO World Heritage Site. More than 10,000 species of flora are spread over its 82-hectares area.
