Tygerberg 3 Student Residence
A pioneer of green construction in student accommodation for the past three decades, STAG African has developed a method of lightweight steel construction which is an alternative to bricks and mortar. Nearly 90 percent of the steel structure is recycled, and no water is required for the construction process, which is carbon neutral. Typically, construction time for the student residences is reduced by 40 percent, building costs are cut by up to 13 percent, and construction waste is lowered from between 25 percent to less than 0.1 percent of building bulk.
In addition to green construction, STAG African implements such sustainability features as LED lighting, shower timers and student food gardens. The 25 units of Tygerberg 3 Student Residence at Stellenbosch University, which achieve thermal comfort without the need for air conditioning or space heating, are powered in part by solar photovoltaics, which provide one-third of total electricity use. The project has received an EDGE preliminary certificate from Green Building Council of South Africa.
Predicted Savings of EDGE Certification
Less Embodied Energy in Materials
Reduced window to wall ratio, reflective paint for tiles and roof, insulation of roof and walls, energy-saving light bulbs for internal and external spaces and common areas, and solar photovoltaics.
Low-flow showerheads, low-flow faucets for kitchen sinks and washbasins, and dual-flush water closets.
Timber floor construction, steel sheets on steel rafters for roof construction, cement fiber boards on metal studs for internal and external walls, and cork and ceramic tile for flooring.
*Part of the energy efficiency percentage may be associated with virtual energy for comfort depending on the presence of heating and cooling systems. Note that virtual energy does not contribute savings to utility bills.
