The Choa Chu Kang Camp, functioning as the DSTA Academy in Singapore, is a significant example of sustainable architecture, certified with the prestigious Platinum Zero Energy award. This certification highlights the project’s commitment to energy efficiency and environmental consciousness. Key green features include a low Concrete Usage Index and the use of Cross Laminated Timber (CLT) for structural support, both of which reduce the building’s carbon footprint. The installation of photovoltaic (PV) panels enables the camp to generate renewable energy, while sun pipes enhance natural lighting, further reducing the building’s reliance on artificial energy sources.
Low Concrete Usage Index (CUI) x Cross Laminated Timber (CLT)
A low Concrete Usage Index (CUI) of 0.254 indicates that the project uses minimal concrete relative to its floor area. This contributes to sustainability by reducing the environmental impact of concrete production, which is resource-intensive and contributes significantly to carbon emissions. A lower CUI reflects a more efficient and eco-friendly construction approach, often incorporating alternative materials like Cross Laminated Timber (CLT).
On this project, the low Concrete Usage Index is achieved by incorporating Cross Laminated Timber (CLT) structures and walls for the 3rd and 4th storeys. This use of CLT not only reduces the reliance on traditional concrete but also enhances the building’s sustainability by utilizing renewable timber, which has a lower carbon footprint compared to concrete. The integration of CLT demonstrates an innovative approach to environmentally friendly construction.
Natural Lighting Optimization Through Sun Pipes
The use of sun pipes in the training rooms, workshops, and other areas on the 1st and 2nd floors provides natural lighting, reducing the need for artificial lighting from morning until evening. This feature helps to minimise energy consumption and enhances the overall sustainability of the building.
Achieving Zero Energy Status Through Innovative Energy Solutions
One of the innovative steps implemented in the building is the use of photovoltaic (PV) panels on the roof. Annually, these panels generate 264,000 kWh of energy, while the building consumes 115,195.13 kWh per year. This consumption is further reduced by the use of sun pipes, which help minimize energy use. As a result, the building produces a surplus of 131,531.05 kWh annually, which enabled it to achieve certification as a zero energy building.
