72 Grayston Drive

72 Grayston Drive, situated in the well-known area of Sandton, Johannesburg, was recently upgraded. This building underwent its transformation in order for it to complement its architecturally chic and modern surroundings. It is located up the road from the renowned Nelson Mandela Square, Sandton City and Sandton Convention Centre. 72 Grayston Drive is a green building and therefore the HVAC installed by IES had to be particularly environmentally friendly but still function optimally. The systems installed are as follows: • Daikin VRV Systems • Toilet Extract Systems • Fresh Air Systems A short system description: The main system is the VRV-IV type with the plant located on the roof level and refrigerant pipes to each individual indoor in-ceiling type unit. BC controllers were installed to distribute the refrigerant to the respective indoor units as per the demand requirements. The overall air distribution for the in-ceilings is via constant volume ceiling diffusers positioned in the ceiling tee. All of the air-conditioning units are controlled via dedicated controllers in each individual area. Anti-vibration mounts and/or spring mounts were installed for all equipment, to absorb the vibration and eliminate sound during operation. Each fresh air supply branch to the hide away units has a butterfly damper fitted onto it. The damper has a quadrant that can be manually actuated to close, open or restrict the amount of air flowing through. Once the required flow rate is achieved, the quadrant can be locked into position. The initial design of the building was changed to suit the client office’s layout and this affected the equipment IES had originally selected. IES had to negotiate with suppliers regarding deliveries and stock availability but was still able to meet the deadline date. Suppliers included: • VRV System: Daikin • Fresh and extract air Fans: Actom • Dx system: Samsung • BMS : Daikin • Air terminals: Strategic Air and Trox Suppliers included: Client: Public Investment Corporation Project Manager: Origin Project Managers Architects: Paragon Architects Mech.

90 Rivonia Road

90 Rivonia, a Redefine Property development, and the new home of Webber Wenzel, is in the heart of Sandton, Johannesburg, and consists of 7 floors of office space that amount to 43 975m². The design of the building placed large emphasis on being environmentally sustainable in terms of energy, water and resource efficiency. As part of this strategy, the HVAC solutions provided by Improvair Environmental Solution needed to adhere to strict guidelines. These included a 100% increase in fresh air provision to enhance mental alertness and dilute incidence of airborne viruses and bacterium, a default set point temperature of 22.5 degrees Celsius and cellular spaces which are fitted with wall mounted temperature adjusters. The CIAT Cristopia (STL) was the system of choice. It’s a flexible and reliable solution for the management of energy needs, enabling a significant reduction in installed chiller capacity (up to 70%), the use of low tariff electricity for significant running cost savings and effective management of cooling according to the real demand. Due to its inherent characteristics and its rapid reaction time the STL improves the reliability of any air conditioning or industrial refrigeration system. The installation comprises among others: -Air-cooled chillers -Ice and hot water storage tanks -Chilled fan coil units with resistance heating and networked control -Ceiling diffusion -Dedicated fresh air provision to occupied areas, incorporating fresh air-pre conditioning -Some extract system -Variable rate basement extract on CO/CO2 control -Bathroom, kitchen and other ventilation as required Suppliers included: CIAT Cristopia Air Handling Units: Viking Air Conditioning Heat Exchangers: CIAT Fan Coil Units: Sinko Pumps: Wilo Controls: Landis and Staefa Electrical Boards: Ushaka HVAC Solutions

Cape Town International Airport

Cape Town International Airport is the 2nd largest airport in the ACSA network and Africa’s 3rd largest airport. It is also Africa’s premier tourist and VIP destination and has established a reputation as Africa’s premier international award-winning airport, consistently performing among the best in the world for service in its category. Cape Town International Airport completed major construction upgrades with the new Central Terminal Building (CTB) at the centre of this expansion.

Moses Mabhida Stadium

With its “arch of triumph”, the Moses Mabhida Stadium is a defining landmark similar to Sydney’s Opera House or The London Eye. In addition to this internationally acclaimed engineering feat, the multi-disciplinary aspect of the stadium’s design allows the stadium to host a wide range of sporting and cultural events, putting it on a par with other international venue’s such as the Stade du France and Wembley Stadium. The Moses Mabhida Stadium has changed the way we view sporting venues in South Africa. A stadium may be venerated as the scene of many an epic clash, but it need not be a monolith that only comes alive on “match day” - or when the members of the band plug in their guitars. The Stadium utilises a chilled water system using 4 chillers and cooling towers, which supply chilled water to ducted fan coll units in the Club Offices and Suites. The basement has a smoke extract system. The various retail areas around the stadium are air conditioned using cooling towers supplying condenser water to water cooled package units.

Green Point Stadium

One of the most artistic football venues in South Africa, the newly- built Green Point Stadium is situated in one of the much sought-after areas in the city of Cape Town. Green Point Stadium is one of the two semi-final venues for the FIFA World Cup™. This multi-purpose venue is also going to be used to stage major events and concerts. Fans will be a stone’s throw from the ocean and the mountains of Cape Town will also provide the backdrop for matches. The stadium has a capacity of 70,000. Several ventilation and fresh air supply systems provide both ventilation / fresh air in normal operation and, in the event of a fire in the stadium, will ramp up in a zone-specific manner to exhaust smoke and provide clean air to the escape routes, lifts and stairways.
