Trapping Less Heat and More Shade at Tengah EC: Computer Simulation Tool and Greenery
The Tengah Executive Condominium (EC) mall in Singapore is a popular shopping destination for locals and tourists alike. As with any urban environment, the heat and humidity can be oppressive during the summer months. To counteract this, developers have employed a number of strategies to reduce the heat and provide more shade. One of the most effective strategies has been the use of computer simulation tools to evaluate the thermal performance of the building, along with strategies such as the implementation of green roofs and living walls.
Computer simulation tools are used to simulate the thermal environment of the building and its surrounding environment. This type of modelling is especially useful as it can predict the impact of different design strategies on the indoor thermal environment. For example, computer simulation tools can be used to evaluate the effects of different building materials, window glazing, shading devices, and other design features. The results of the simulation can then be used to inform the development of strategies to reduce the heat gain of the building, and ensure the required level of thermal comfort is achieved.
At Tengah EC, the developers have employed a number of strategies to reduce the heat gain of the building. One of the key strategies has been the implementation of green roofs and living walls. These features provide a layer of vegetation that can act as a barrier to the sun’s rays, reducing the amount of heat that is absorbed by the building. They also help to improve the air quality of the surrounding environment, as the plants absorb carbon dioxide and other pollutants from the air. The vegetation also provides an aesthetically pleasing addition to the building, adding to its overall appeal.
In addition to green roofs and living walls, the developers have also implemented other strategies to reduce the heat gain Tengah EC of the building. These include the use of shading devices such as sunscreens, awnings and louvres, as well as reflective coatings on windows and other building surfaces. The use of these devices can significantly reduce the amount of direct sunlight that enters the building, while still allowing natural light to enter. This helps to ensure that the indoor environment remains comfortable, while still providing adequate levels of natural light.
Finally, the developers have also implemented strategies to improve the thermal performance of the building. This includes the use of high-performance insulation materials, as well as the installation of energy efficient cooling and heating systems. The use of these strategies helps to reduce the amount of energy that is required to maintain a comfortable indoor environment.
Overall, the developers of the Tengah EC mall have employed a range of strategies to reduce the heat gain of the building, while still providing a comfortable indoor environment. These strategies include the use of computer simulation tools, green roofs and living walls, shading devices, and energy efficient cooling and heating systems. By employing these strategies, the mall is able to provide its customers with a comfortable shopping experience, while still reducing its environmental impact.
In Singapore, the high temperatures and humidity can be stifling, especially in the residential estates of Tengah. The challenge is to provide better living conditions for residents without relying solely on air-conditioning. Fortunately, the Housing and Development Board (HDB) has developed a computer simulation tool to help designers come up with feasible strategies to trap less heat and provide more cooling shade in the Tengah estate.
The computer simulation tool uses the Ray Tracing Method to calculate the amount of solar radiation that is received by the building façade and rooftop. It compares the energy performance of different façade materials and building designs to determine which ones are most effective at trapping less heat. The tool also evaluates the effectiveness of greenery strategies such as green roofs, green walls and vertical gardens.
HDB’s data-driven approach helps to identify the most effective strategies to reduce heat island effect and to improve the microclimate of the Tengah estate. For example, the tool can reveal how certain façade materials can absorb and reflect the sun’s radiation differently, thus affecting the heat gain inside the building. It also shows how the position and orientation of the building can influence its energy performance.
The simulation tool can also inform designers on the best ways to integrate greenery into the building design. Green roofs, green walls and vertical gardens can all provide natural cooling shade and reduce the heat island effect. Furthermore, these greenery strategies also provide other benefits such as improved air quality and biodiversity.
HDB has also implemented a suite of green initiatives to reduce heat in Tengah. These include solar shading devices, cool roofs, green walls and vertical gardens. Solar shading devices such as trellises, louvres and pergolas help to reduce the amount of direct sunlight reaching the building façade. Cool roofs are designed to reflect solar radiation away from the building, thus lowering the temperature of the roof surface. Green walls and vertical gardens also help to reduce the amount of heat absorbed by the building façade while providing a pleasant visual and living environment.
In addition to designing buildings to reduce heat, HDB has also implemented a number of public realm strategies to improve the thermal comfort of the Tengah estate. These include shading trees, permeable pavements and water features. Shading trees provide natural cooling shade and reduce the heat island effect, while permeable pavements help to cool the air temperature and reduce the heat island effect. Water features such as fountains and ponds also provide evaporative cooling, helping to reduce the overall air temperature.
Overall, HDB’s efforts to reduce the heat and improve the living conditions of the Tengah estate are commendable. The computer simulation tool and the various greenery and public realm strategies have all contributed to creating a more comfortable and pleasant living environment for residents. In the future, HDB could look into other technologies such as geothermal cooling and phase change materials to further reduce heat and enhance the thermal comfort of the estate.
