NATIONAL ORCHID GARDEN · SINGAPORE
RENOVATION
The National Orchid Garden in Singapore selected Onyx Solar’s technology to provide clean energy to this unique UNESCO World Heritage Site. This photovoltaic skylight is composed by trapezoidal Insulated photovoltaic glass Units with 12 mm air chamber to achieve the needed thermal insulation to keep an indoor optimal temperature to grow orchids. The glass selected was customized to reach 51% of visible light transmittance and 40% SHGC (g-Value). Onyx Solar’s involvement required fabricating 15 different glass dimensions and trapezoidal units to accommodate the complex geometry of the existing metal frame.
In addition to meeting the garden’s energy requirements, the photovoltaic glass integrates seamlessly into the architectural design, enhancing the aesthetic appeal of the space while providing functional benefits. The careful customization of the glass units ensures they are perfectly aligned with the garden's needs, particularly in regulating the environment necessary for the healthy growth of the orchids. The skylight not only supplies renewable energy but also helps in reducing the operational costs of the garden by optimizing the natural light and temperature management. Onyx Solar’s contribution to this project highlights how modern photovoltaic solutions can be adapted to sensitive, high-profile environments, supporting both sustainability and the preservation of natural ecosystems.
"The Cool House is designed to emulate a high elevation forest, which exists at altitudes of 1.000m to 2.000m, and with a surrounding temperature of 16°C to 23°C. Having in mind the extreme weather conditions of Singapore the selection of high performance glass with optimal passive properties was decisive."
The Singapore Botanic Gardens, a world-renowned tropical garden, is a symbol of sustainability, biodiversity, and conservation. As a key green space in the heart of the city, the Gardens are committed to promoting eco-friendly practices in their operations. By choosing Onyx Solar’s photovoltaic glass, the Singapore Botanic Gardens enhance energy efficiency, supporting their mission to reduce environmental impact while preserving natural beauty and biodiversity for future generations.
The UNESCO World Heritage designation represents a commitment to the preservation and protection of cultural and natural sites of outstanding global value. Many UNESCO-listed locations, including urban and environmental spaces, are integrating sustainable energy solutions to support conservation efforts. By incorporating Onyx Solar’s photovoltaic glass, these sites not only reduce their carbon footprint but also serve as global examples of how heritage preservation and sustainability can coexist.
