When MGPA wanted to increase HVAC efficiency systems to address stringent
indoor climate and temperature requirements for the development’s Tower 1,
they set out to find a partner with the know-how and capability to enable
precise temperature control with optimized efficiency. As such, TA Hydronics
proved to be the partner with the perfect solution.
The Asia Square Tower is a £633 million
twin-tower, mixed-use development at
Marina Bay, Singapore, one of the key
financial centres in the region. It comprises a
305-room five-star Westin Singapore Marina
Bay Hotel on the 32nd to 46th levels,
190,000m2 of Grade A office space and
5,600m2 of retail space.
The challenge
With many mixed-use development buildings,
it is essential that care is taken to balance
out what can be differing indoor climate
requirements between the hotel, retail and
office spaces of the building while delivering
excellent energy efficiency. At the same
time, Singapore’s equatorial marine climate
meant that the comfort of the interior
environment for residents, visitors and
building employees was highly important.
The solution
A meeting between TA Hydronics and
consulting engineers AECOM and Meinhardt
provided the company with an in-depth
understanding of the customers’ indoor
climate and temperature objectives for the
43-storey Tower 1.
Following this meeting, it was agreed that
the establishment of efficient hydronic
balancing of the system was essential.
However, it was clear TA Hydronics faced
some interesting challenges. One of these
concerned the supply of chilled water from a
District Cooling plant that led to special
technical requirements for maintaining the
differential temperature (∆T), otherwise the
supplier may face heavy fines from the
municipality. Another was a secondary pump
head of 12 metres, an almost unheard of
challenge.
The first step in reaching the optimal
solution was to review the existing system.
TA Hydronics began with a thorough analysis,
measuring differential pressure, flow and
temperature inside the chilled water system.
TA Hydronics’ proven TA Select 4 hydronic
calculation software was then used for
hydronic calculation and component
selection for a complete system solution in
order to minimise energy use and provide
accurate temperature control at individual
room level.
The outcome
Through a combination of high performance
STAF and STAD balancing valves, STAP and
DA516 differential pressure controllers, as
well as pressurisation maintenance systems
Compresso and Pleno, TA Hydronics provided
the ideal solution which delivered outstanding
efficiency and increased indoor climate
comfort.
Asia Square has achieved both the Leadership
in Energy & Environmental Design Core &
Shell (LEED-CS) Platinum certification by the
US Green Building Council and Green Mark
Platinum Award by the Building and Construction
Authority of Singapore, making it one of Asia’s
greenest buildings.
With the indoor climate and temperature
requirements of Tower 1 successfully met,
hydronic distribution systems from TA
Hydronics have also been specified for the
development’s 46 storey Tower 2, which,
to be completed in 2013, boasts a Westin
hotel, 72,465m2 of Grade A office space
and 3,717m2 of retail and F&B space.
