CIBSE NEWS | YEN IN MALAYSIA The global chairs of the Young Engineers Network met in the Far East for their annual conference in November and had the opportunity to see the latest mega developments in Singapore and Kuala Lumpur, as well as a green Heriot-Watt campus in Putrajaya NETWORK FAR EAST O n 11 November 2019, 23 chairs and vicechairs from CIBSEs Young Engineers Network (YEN) headed to Malaysia for a week of activities to learn about building services in the region. Included in the group were young engineers from across the UK, Hong Kong, New Zealand and UAE. Young Engineers of ASHRAE (YEA) chair Vanessa Freidberg also attended, along with CIBSE President Professor Lynne Jack and Roisin Sweeney, of CIBSE Membership Services. First port of call was a trip to Putrajaya, where the young engineers learned about the towns masterplanning by architect Serina Hijjas. The city has 38% designated green space and the plans have spare utility tunnel provisions under the main promenade to allow for future expansion. The towns masterplan also has a requirement for educational buildings, and this is where the Heriot-Watt University Malaysia campus has been established. There is 67% green space with several sustainability features. Located at the edge of Putrajaya Lake, the campus is naturally ventilated, and the breeze coming off the lake enabled the designers to pursue a cross-ow ventilation strategy. Shading facing the lake minimised solar gains. An arcing green roof rises from the ground oor of the university and extends the length of the building. At around 9,000m2, it offers an area for students to gather, and was positioned so any buildings overlooking the campus would only see the green of the roof as they looked towards the lake. The presentation was followed by a tour of the campus to see these systems in operation, explore the plantrooms and walk across the massive green roof. The mix of nature and technology on the campus typies the design philosophy of the Putrajaya masterplan. There was further evidence of this in the Above: YEN and YEA chairs and vice-chairs, and CIBSE president Lynne Jack groups next destination, the Diamond Building, which is the home of Suruhanjaya Tenaga, the Malaysian Energy Commission. Here, the head of facilities management told the group about the history of the organisation, the legislation it had passed and the energy efciency measures used in its building. The building optimises daylight from the dome at the top of the building, which serves the central atrium space, to the diamond shape of the building itself where the external glazing is sloped downwards with low emissivitylevel glazing to minimise the risk of high solar gain. Other measures include PVs on the sloping roof, trees planted on the street to shade the entrance and slab cooling overnight.
