Energy Saving Solutions for Buildings

South Africa is currently suffering from a low energy reserve margin with a growing demand our infrastructure cannot meet.
As a Member of Green Building Council of South Africa (GBCSA), DFR Engineers is obliged to ensure the preservation of our available energy resources.
There are two phases to achieving energy efficiency, namely, Passive Energy Efficiency and Active Energy Efficiency, the latter being dependent upon the first.

PASSIVE ENERGY EFFICIENCY

This method includes efficient devices and installation and so providing a baseline for optimized energy efficiency. The following is included:

• Installing low consumption devices
• Well-insulated building envelope
• Roof insulation
• Sealing
• Well-insulated hot water pipes
• Walls and Fenestration

ACTIVE ENERGY EFFICIENCY

This method is needed to optimize and sustain the gains from passive energy efficiency and to provide additional saving. This can be achieved by system automation and regulation:

• Lighting Control Systems
• Heating, ventilation, air-conditioning
• Building Management systems
