Park Royal at Pickering is a 7500 sq.m. Hotel in the thick of Singapore’s Central Business District, facing a now famous Hong Lim Park. The hotel has various sustainable features (elaborated below), that lead to approximately 30 per cent (f) energy savings in operation (using a conventional building of similar scale and functions as base case). Due to these features, it has received the GreenMark Platinum rating certification from Singapore’s Building Construction Authority.



  • Horizontal air movement
  1. Despite being a commercial project, the property shows generosity, by providing a large public interface on the ground floor. This enables Horizontal air flow, thus improving thermal comfort for the area.
  2. The corridors, lobbies and common wash rooms are all naturally ventilated with fresh air (c).
  3. The entrance to the above-ground car park is concealed with plants and is also naturally ventilated.

This natural ventilation in humid Singapore conditions, provides relief to occupants. The breeze, coupled with shading measures, can improve thermal comfort conditions; thus reducing the need for artificial mechanical cooling.

Cleantech One is a 37,500 sq.m. BCA GreenMark Platinum certified Industrial building. It is a Jurong Town Corporation project that is part of the larger Cleantech Park, which is a 50 hectare site for clean technology activities such as R&D, test-bedding, prototyping. Cleantech One employs state-of-the-art Active technology features, but also integrates Passive design catering to its Climatic context (Singapore).

Singapore has a tropical rainforest climate, with temperatures rarely straying from 29-30 degrees Celsius. Humidity stays high throughout the year and there is regular and heavy precipitation. The effect of temperature can be reduced by strategic shading measures. Cleantech One uses proper orientation, green walls, planters, sky trellis. Humidity is addressed by increasing air movement to provide potential relief to occupants as seen below. These measures reduce dependence on mechanical cooling and thus help decrease Energy costs.
