New Green Building Regulations for Warehouse Design
Category Market Trends and Industry News
The new Green Building Regulations, detailed in the SA Bureau of Standard SANS 10400 XA, are enforceable, in terms of the National Building Regulations and Building Standards Act. They came into effect late 2016.
There are a few new regulations that should be highlighted:
- All new buildings must use solar water heaters or heat pumps.
- Ceilings, walls and windows must meet minimum requirements in terms of insulation, to minimise heating in winter and cooling in summer.
- Buildings must use energy efficient heating, energy efficient air conditioning and ventilation systems.
Green buildings incorporate design, construction and operating practices that reduce or eliminate the negative impact of development on the environment and the occupants. The Green Building Council scores buildings in nine categories, namely:
- Indoor Environment Quality
- Land Use
The new building regulations have legalised many of these practices. Here follow the aspects that have been brought in to the new legislation:
- Building orientation
- Window sizing and positioning
- Shading, and choice of materials with respect to thermal and insulation properties as well as natural cooling
- Roof structure
One of the biggest focus areas for new warehouses is the roof structure. Small changes in the design, colour and insulation of the roof have a major impact on the warehouse. A cooler roof is one of the most effective solutions to lowering energy consumption. The roof reflects the sun and emits absorbed radiation back into the atmosphere. A cooler roof will keep the building at a more consistent temperature.
A cool roof does not have to be white, as there are other variations that will have a similar impact. Insulation material prevents the internal temperatures from rising too fast or dropping too quickly. This, together with the cooler roof, will ensure that temperature control in warehouses is improved for all new buildings in the future.
These new Green Building Regulations are generally a step in the right direction, and most competent builders and developers will have incorporated most of these into their new buildings before the new regulations came into effect.
