Interior public spaces make extensive use of FSC European oak with a grey oiled finish Incorporating the above, this real estate solution needed to solve long-term parking issues, enhance safety and security aspects and maximise value for Chevron in the long-term. The spaces would need to be flexible, modern, ergonomic, and technology-enabled to allow people to work productively and promote Chevron as an employer of choice. Finally, it would need to be a building representative of Chevron’s corporate image. An important consideration was the inclusion of the green star applications within contractual documentation, as well as the related specifications. The team worked closely with the sustainability consultants in preparation of all tender documentation and ensured Chevron’s sustainability brief was met and was to their global standards. Sustainability As part of a global entity that is committed to reducing its environmental footprint, as well as an employer of choice in the Western Cape, Chevron required the building to be certified against the South African Green Star standard, as well as the internationally recognised LEED standard for green buildings. Some Key Sustainability Designs • Double glazing to façades • Aluminium shading panels throughout which were modelled for optimisation • Anaerobic biodigester for biodegradable waste generated by the kitchen which diverts around 700 kgs per month from landfill • Ample natural light, views and courtyard use with Wifi for staff to work from. • Low VOC paints and sealants • Heat recovery chillers with no geysers and electrical heating of hot water. • HVAC chillers generate the hot water and act as heat pump • Water dispensing systems for meeting rooms and staff. This reduced the use of plastic water bottles significantly. Part of the approved zoning by council was a requirement for all stormwater to be treated through a sedimentation chamber before being discharged. The sustainability consultants used this pre-existing design requirement to build the water-use strategy with re-use of all stormwater within the building. The building aimed to reduce energy consumption through the following strategies: • Efficient and intelligent lighting systems. • Enhancing daylight usage. • The HVAC system has the ability to heat and cool the building, at the same time utilising efficient built-in heat pumps. Variable speed fans only operate at the speed required. When outside air temperatures are favourable, 100% of fresh air is supplied to the building. • Double glazed performance glass reduces the amount of heat gain and loss of the building. • Energy modelling to optimise shading وB
