Maritime and Port Authority (MPA) of Singapore, embarking on creating their first building development have targeted to achieve Green Mark 2021 Platinum SLE and PE with all badges for 2 of their blocks at a development in Tuas. This directly comes from their sustainability agenda as follows:
TARGET TO BE THE FIRST ZERO ENERGY DEVELOPMENT WITH ALL GREEN MARK BADGES
To take precedence in sustainability features, MPA Building targets to be the first commercial building with a control center to achieve zero energy with all GM badges. The entire development is covered in PVs to harness the highest amount of solar energy as possible. MPA also plans to explore using mini wind turbines and water turbines across the development as trial technologies to generate additional energy on site.
Passive Design
The entire development is designed on the principles of passive design, especially the wind tunnel effect, known as the “venturi effect”. This particular design element helps introduce North-East wind into the development through a thin tunnel-like space that cools the wind down and creates a cool outdoor environment in the thoroughfare between the 2 blocks. This design was guided by intense Computational Fluid Dynamics studies to analyze the wind direction and wind speed.
Passive Displacement Cooling
PDC is an energy-efficient air conditioning system that relies on natural convection to circulate cool air. It works by supplying cool air at floor level, which then rises as it warms up due to heat from occupants and equipment. This creates a natural convection current that draws in more cool air from the supply, effectively cooling the space without the need for mechanical fans. This system greatly helps reduce the energy consumption on the air side system in MPA Offices.
Energy Optimization
Building Attached Photo-Voltaics (BAPV)
(BAPV) modules have been used in place of regular cladding on the eastern and western façades of the building. BAPV is one of the promising renewable energy technologies, and its use in parts of a building envelope such as the roof, skylights and facades that will generate a sustainable PV power.
