Elements – Integrated Renewable Energy & Resource Efficiency Programme

iREREP Elements

iREREP is the official national Programme for Resource Efficiencies and Renewable Energy for Government facilities in a bid to meet sustainability targets of Government and South Africa at Large.

The Department of Public Works and Infrastructure (DPWI), supported by the Government Technical Advisory Centre (GTAC) has developed a programme that is aimed at rolling out:

Energy Efficiency

The Energy Efficiency element will procure energy savings through various technologies that seek to:

Improve thermal performances of building envelope

Improve HVAC and Refrigeration system performance

Reduce Energy consumption to produce hot water

Improve lighting system efficiency

Reduce electricity consumption via Monitoring and Control systems

Improve efficiency of electric system

Improvement of general process equipment

Improvement of special process equipment

Water Efficiency

The Water Efficiency element will procure water savings and water conservation through various water efficiency technologies including:

Water Efficiency Systems

Low-flow and water efficient dispenser

Leak Detection

Heating and Cooling

Food preparation

Water treatment

Water harvesting

Automatic and Sensor systems

Steam system retrofits

Landscaping

Irrigation

Water Efficient Appliances

Renewable Energy Generation

The Renewable Energy element will procure renewable energy technologies including:

Solar PV – Ground Mounted and Rooftop – in line with SSEG Regulation fom NERSA

Wind Energy

Biomass

Hydro

Geothermal Energy

Tidal

Energy Storage

Improvement of special process equipment

Alternative Waste Management

The alternative Waste Management element of the Programme will procure waste management services that provide alternative solutions to the current waste management practices. The solutions must ensure diversion of waste from landfill and also make considerations for possible revenue generation opportunities through waste commercialization. The solutions to be procured will include:

Sorting of Waste

Recycling

Waste to Energy

Hydro

Anaerobic Digestion

Composting/Organic Waste Recycling

Advanced technologies (Pyrolisis, Gasification)
