Whether you own/rent your own warehouse or pay for warehousing services, a best-in-class green warehouse would consider the following green initiatives at the building level:

  • Adherence to the Code for the Environmental Sustainability of Buildings drafted by The Building  and Construction Authority of Singapore which has largely adopted the  Green Mark’s criteria as the compliance method for assessing the environmental performance of a building development. At the end of the construction the building receives a Green Mark score for its environmental performance.
  • Adherence to a recognised environmental management system such as ISO14001, possibly with a certification such as Green Mark Platinum or Energy and Environmental Design Gold Certification can be a good start to improving carbon emissions. Some warehouses claim to be carbon net-zero and need to justify this (CarbonZero, CEMARS certification).
  • The design and construction of a warehouse is the preferred stage to optimise future energy consumption of the facility: use of eco-concrete and other green building materials, orientation of the building to maximise daylight source and minimise heat from the sun, building vertically,  layout to minimise travel, maximise greenery around the warehouse, collection of  rainwater for gardening or toilets, use of water efficient sanitary ware.
  • Next is the energy of the building. Obtaining the electricity consumption (in kWh/sqm) is a good way to benchmark the energy efficiency of the warehouse. Then, switching to a utiliy provider or electricity plan that uses renewable energies rather than gas/fuel-mixed power from the Singapore grid is another good way to reduce the carbon impact.
  • Utilising the roof or land area to install photovoltaic panels is a great way to reduce the carbon impact of the warehouse operations.
  • Energy efficiency can be improved with an efficient air conditioning system, cooling system, roof and window insulation, solar shading, solar water heating.
  • Investing in a Building Management System (BMS) with automatic control of solar blinds and sun louvres, automatic control of windows for natural ventilation, automatic control of plant and systems, integrated with lighting control system, temperature control and door control. A BMS can provide an energy and water monitoring system and help identify areas for improvement.
  • Switching to LED lighting where required
  • Consideration with regards to neighbourhood inconvenience (noise, odour, dust).

The Green Mark certification scheme was launched in January 2005. It is a green building rating system designed to evaluate a building’s environmental impact and performance. It provides a comprehensive framework for assessing the overall environmental performance of new and existing buildings to promote sustainable design,and best practices inconstruction and operations in buildings.

Most existing air-conditioning systems use refrigerants from the HFC gas family (hydrofluorocarbons) which are extremely harmful to the environment. The detection of gas leakage and the recovery of refrigerants at end of life is crucial to avoid GHG emissions to the atmosphere.
For new built, it is encourage to opt for low Global Warming Potential refrigerant gases such as R32 or R290.

Singapore has a roadmap to reduce emissions from refrigeration & air-conditioning
