Creating green buildings the common objective is to design a structure to reduce the overall impact of the built environment on human health and the natural environment by efficiently using energy, water, and other resources, protecting occupant health and improving productivity, reducing waste, pollution and environmental degradation.


Proper siting and placement, efficient structural design.
Energy efficiency through highly insulated building envelope, proper orientation, assesment of renewable energy sources.
Heating, ventilation and cooling system efficiency.
Application of sustainable building materials, such as recycled materials.
On-site waste management, such as grey water systems for use on garden beds, and flushing toilets, on-site food waste composting and off-site recycling.


Green building rating systems such as BREEAM (United Kingdom), LEED (United States and Canada), DGNB (Germany) help consumers determine a structure’s level of environmental performance.
They award credits for optional building features that support green design in categories such as location and maintenance of building site, conservation of water, energy, and building materials, and occupant comfort and health.
The number of credits generally determines the level of achievement.
