The Green Star is a points-based green building rating system that evaluates buildings according to global best practice in sustainability. The system allocates points across nine categories including management, indoor environmental quality, energy, transport, innovation and water, materials used, land use and ecology and emissions. As no Green Star existed for hotels, a customised tool was developed for the project.
The surrounding industrial and warehouse setting of the working harbour and the Zeitz Museum of Contemporary Arts Africa (MOCAA) has been articulated in the design of the building. Concrete and face brick therefore form an integral part of the architecture, giving the hotel a contemporary aesthetic look and ensuring low maintenance.
The building is spatially efficient with low VOC finishes. Good levels of natural lighting, together with appropriately designed facades, ensure maximum efficiency of resources. An independent commissioning agent was appointed to manage the commissioning and tuning process, which ensures optimum operations of the building.
The opportunity to install district-wide services for the various buildings was identified early in the planning of the Silo District. With major initiatives such as the centralised district sea water cooling and heating plant being among the most high-profile interventions, other simpler initiatives such as the shared potable water and fire sprinkler water tanks cut down on the amount of water required to be stored as well as reducing the space in the car park taken up by multiple individual tanks.
Other stand out sustainable features considered by the GBCSA includes:
The Radisson Red Hotel, which opened in late 2017, was part of the international hotel group Carlson Rezidor’s first new concept upscale lifestyle hotels in Europe, Africa and the Middle East (EMEA).
“We are super chuffed about the award and to showcase this plaque at the hotel for our guests to see. Red is an attitude with a Green mindset about our responsibilities to run a business sustainable," says Leonie Andereya, curator and general manager for Radisson Red.
The ground floor of the hotel houses the reception and welcome area, event and meeting spaces and the restaurant. The first floor is set aside for back-of-house functions while floors two to eight house guest rooms. A gym, lounge bar and pool deck with panoramic views are located on the roof level.
“The GBCSA acknowledge the role that the hospitality sector plays in raising awareness about sustainability and how travellers are increasingly requesting accommodation and transport options that reduce their carbon footprint. No 6 Silo is an example of a green hotel that connects guests to alternative city transport options, precinct scale services that optimise efficiency (such as the innovative central seawater cooling plant) and attention to detail when it comes to dematerialisation in the interior finishes," says Georgina Smit, GBCSA head of technical.
"We take a holistic approach to sustainability, and this was the key principle behind our developments at the Silo District, and elsewhere in our developments. Every element of new developments are scrutinised to maximise the efficiency of the design and the operation of the buildings," says Vusi Nondo, executive manager for development, V&A Waterfront.
