It is said that 80% of the world’s cranes are
working at construction sites in China. ESRU Consultancy has recently expanded
its international portfolio of consultancy services by securing energy conservation
project contracts for the Terminal Two Shanghai Pudong Airport.
THE CONTEXT
Designed
to handle 20 million passengers a year, the current
ultramodern Shanghai Pudong Airport
(PVG) started operation in 1999. The
Phase Two development includes a second terminal
building, a 1.4 km long passenger lounge, car parking and roadway system and a
'people mover system' for transfer of passengers between terminal buildings.
This will add another 40 million passengers a
year to the existing passenger-handling capacity. The
430 km/h high-speed Maglev Transrapid train links the 35 km distance downtown
Shanghai to the Airport in just eight minutes. City officials said that Pudong Airport will eventually have four terminal buildings
and four runways before the 2010 World Expo.
The
new terminal building is a very advanced design, in terms of both
appearance and efficiency. The US$980 million, GFA 500,000 m2
project has involved some of the leading architects and consulting engineers of
the world, including ECADI, SOM, DHV (NACO), DEDI (CPG), etc. Not only does the
building have an enormous scale, but the single span triple sweeping waveform
roof with ‘blinking eyes to the sky’ provides the form and fabric and an
interior space that offers challenges for architects, planners and
engineers.
THE
PROJECT
The design
was initially awarded to ECADI, one of China’s leading architectural design
firms. Being one of the largest airports in the world, the Shanghai Airport
Authority (SAA) is aware of the immense potential in terms of energy
conservation and environmental impact.
To assist
the design team, ESRU was recommended to the SAA by the Shanghai Pacific Energy
Center (SPEC) to provide simulation design support expertise to the design team
in the area of energy conservation, passenger visual and thermal comfort, and
fire and safety. Requested by the SAA, ECADI subcontracted independently a
leading European environmental design consultant to carry out similar
simulation exercises for unbiased comparison and validation. ESRU’s initial
assignment included a feasibility study for using natural ventilation during
the transition seasons, the potential for energy saving and its impact on the
functions of the building as a whole. ESRU’s software packages, ESP-r and
Cflo3, were applied to the tasks. Various strategies and schemes for natural
ventilation were investigated and economic analyses for the operational schemes
were carried out.
THE
OUTCOMES
ESRU,
together with SPEC, provided the design team with accurate and rational
information regarding the design options for the building. This enabled the
design team to clearly understand the features and effects of the design
options before the building was constructed. At the project meeting organized
by SAA, ESRU staff presented the simulation results against simulation results
from other consultants. The design team was extremely impressed by the
accuracy of the results and the quality
of the presentation delivered by ESRU staff.
CLIENT
COMMENTS
SPEC
commented: “We are extremely pleased to have recommended ESRU to SAA and the
design team”.
ECADI
said: “The quality and expertise of ESRU’s work have proved superior and second
to none. We are looking forward to working with ESRU on further design issues
of this project and new projects in the future”.
