Expert: Sustainability should work through building life cycle

Sustainability is not just a design aspiration, but it’s something to work through the life of the building, said Hywel Davies, CIBSE technical director, at a conference held in Dubai

Sustainability is not just a design aspiration, but is something to work through a building's life cycle, said Hywel Davies, CIBSE technical director, at a conference held in Dubai.

Davies was talking at a Chartered Institution of Building Services Engineers' (CIBSE) conference held on 1 November that addressed the challenges of tall building design.

Davies spoke about sustainability and tall buildings. He stated during his presentation that the number of tall building is increasing worldwide.

He pointed out some of the challenges facing construction in tall buildings:  “Thirty percent of global greenhouse gases emissions are attributable to buildings. There is a growth of megacities around the world and significant number of that is in the Asia pacific region.”

Some of the technical challenges of building tall according to Davies were: vertical transport – lift or elevator, air pressures and movement – stack and pressure effects, hydraulic pressures – commissioning and handover, energy management, and maintenance and ongoing work.

When it came to sustainability, Davies said: “We can have a sustainable design but if that design doesn’t get build and commissioned properly and handed over to the client and the people who are responsible for maintaining and operating it are not properly trained, then your sustainable design is not going to give you a sustainable building."
