It’s obvious that PARKROYAL on Pickering is a feast for the eyes with its vegetation-wrapped glass reinforced concrete layers, but it’s not just a pretty facade. The building was awarded Green Mark Platinum status in 2012 by the Singapore Building and Construction Authority (BCA) for its energy and water saving design, which includes motion-activated lighting, naturally-ventilated hallways, recycling in guest rooms as well as throughout the hotel, energy-efficient chiller system, demand-based ventilation systems, use of LED and fluorescent lighting, daylight maximization, photovoltaic cells on the roof, high performance glass to cut solar gain and use of Cobiax technology (which uses “void formers” made of recycled plastic to reduce concrete usage), just to name a few of the eco-conscious considerations. The building’s foliage also works to absorb heat and keep the west-facing walls cool (a must for a tropical climate like Singapore’s), but you might be wondering how much extra energy goes into watering and maintaining all of those plants. The answer? None.
“All of the surface rainwater runoff is channeled down to the greywater harvesting tank to water all of the gardens, and they are watered by gravity-driven irrigation,” Bernard Lee, an architect that was part of WOHA‘s PARKROYAL project team, told us. “We also have photovoltaic cells on the roof to provide energy for this process.”
Mr. Lee also explained WOHA‘s vision to mirror the neighboring Hong Lim park in their design. “For this building it was WOHA’s direction to go with green replacement – how do we not just conserve the greenery in the urban setting but also multiply it? Therefore we looked into using vertical greenery to replace all of the greenery that was lost,” he said. The result was a total foliage cover that constitutes more than 200% of the structure’s total land area.
