Day Lighting Planning
Thermal Comfort achieved by different sides of facades
Natural Daylight Of Diamond Building The unique shape of the Diamond Building is designed according to the climate and sunlight path of equatorial Malaysia. Solar energy research shows that the 25° inclination angle of the facades can ensure that the north and south facades are completely self-shielding throughout the year, while reducing the solar impact of the east and west facade by 41%.
Sunlight diffuses and reflects from the landscape, thereby reducing the heat absorption of the building.

The soft landscape and water features create a cool and tranquil outdoor atmosphere, complementing the concept and function of the Diamond Building. The greenery in the sunken landscaped garden on the ground floor helps reduce the heat absorption of the building and the streetscape lined by tall trees has a shading effect. 1

Daylight is reflected from the lightshelf and window sill, and cast onto the ceiling, which can provide effective natural lighting for the interior of the office together with the light frame. Fixed blinds help prevent glare and help reduce the heat island effect.

The rest area outside the small theater is a skylight, which mainly absorbs the diffuse light from the southern part of the sky. By introducing enough light to illuminate the rest area, and eliminate the need for electric lights during the day. Prepared by LIM JIANG WEI 1001747632

Why Is Sunlight Used Wisely In Diamond Buildings ?

The atrium has been carefully designed and equipped with six automatic blinds in different configurations. From the dome on the roof to the sunken garden and parking lot, every space in the Diamond Building is functionally designed with the most advanced technology. Its various configurations help prevent direct sunlight to optimize the indoor and outdoor environment Quality and avoid the visual glare problem of occupants.
The transparent dome forms the central atrium, designed to optimize daylight. One side of the atrium is lined with four- and five-story Tannenbaum reflectors, which can deflect light to the lower floors with the lowest daylight. The inclination of the mirror is 10 degrees and reflects approximately 85% of the light in a semi-diffuse manner.

Natural Cross-Ventilation The inverted pyramid shape directs the wind to the basement, where there is a cross ventilation system. The building has a “sunken garden” in the basement, which is used as an open space to provide natural ventilation for the basement parking lot. Therefore, the ventilation fan almost never turns on.
Wind flows down to the basement for cross ventilation
Adequate greenery around the building brings cooling effect to the building

Green plants on the roof can reduce the outdoor temperature by up to 5°
Green roof and surrounding natural landscape Approximately 20% of the area is dedicated to green plants on the roof to provide a barrier against the heat island effect and enhance the cooling effect from the roof to the building. Prepared by LIM JIANG WEI 1001747632
The sunken garden allows the building to be surrounded by nature, providing a cooling effect for the building 4
