Cundall’s new Hong Kong office is a showcase in how to cost effectively deliver a first-class office fit-out whilst creating a healthy, efficient and future proof space that is both kind to the environment and puts the wellbeing of occupants at the heart of the design. The office located on the 7th floor of The Hennessy, has been designed to incorporate as many WELL Building Standard™ and LEED principles as possible.

The main office area is open-plan and flooded with natural light from the 4.5m floor-to-ceiling windows. Some 90 percent of the office workstations have access to views and, by installing PVC- free blinds against the windows, solar glare is controlled to optimise visual comfort.

An upcycle approach has been incorporated within the sustainable building design, with a conscious decision to reuse existing materials rather than buying new alternatives. 1770kg of waste was diverted from landfill, almost 1427kg CO2 saved from disposal emissions. The most striking expression of this approach can be found in the feature wall within the reception area which utilises reclaimed wood from an old Hong Kong fishing trawler that once worked the South China Sea.

Without compromising the design and effectiveness of the lighting, fluorescent light fixtures have been reused from Cundall’s previous office to create a comfortable lighting scheme that meets both WELL and LEED standards. Costs-in-use are kept to a minimum by using efficient lighting with occupancy-detection and daylight-dimming controls. By placing luminaires only where they are needed, rather than flooding the floor with unnecessary illumination, a 25 percent better lighting power density than the ASHRAE 90.1-2010 standards has been attained, as well as gaining maximum points against the interior lighting power credit under LEED.

Bearing circadian rhythms in mind, all workstations have at least 200 equivalent melanopic lux present between the hours of 9am and 1pm, which the sensor will automatically reduce if the light levels are too high (after 1pm). Pendant lights from the previous meeting room have been upcycled and re-used in the new office breakout area and, by using colour-changing lightbulbs that can be operated via remote control, an adaptable and flexible space has been created to suit various functional needs and moods.

An innovative ventilation solution that uses pre-fabricated fabric air ducts has been incorporated into the building design. The system does not require installation of metal ductwork, diffusers and insulation material and is thus quick to install. The fabric air duct creates great comfort, is condensation free, hygienic and healthy.

Harnessing the latest information technology, an interactive building performance dashboard developed in-house (IEQube®) will monitor the indoor air quality – as well as energy usage – of the office, with the data displayed via a live feed to monitors in the breakout area.
