|UPPER GRAYSTON BLOCKS E & F
Are Green Buildings
The Green Building Council of South Africa awards a Green Star rating on the basis of the building’s design. The Green Star rating system rewards building projects for achieving energy conservation goals in the categories of: Management, Water, Indoor Environmental Quality, Materials, Energy, Land Use and Ecology, Transport and Emissions.
|Brydens Upper Grayston Block F has been awarded a 6 Star As-Built Rating from The Green Building Council of South Africa.|
|Block F is equipped with a rooftop photovoltaic solar panel array. These convert sunlight directly into electricity. 15% of the energy used in the building comes from this installation.|
|Passive architectural design
The architect has made use of good design principles appropriate for our climate. The building is effectively shaded from sun in summer, but in winter sunlight may enter and warm the building. This reduces the need for heating and cooling energy and results in energy conservation.
|Live online energy and water display
Every tenancy in the building is equipped with smart meters measuring the lights, air conditioning and other office equipment. Making this data available online and displaying it in the foyer enables users to manage building energy conservation.
|Lights and lighting control
Blocks E & F use the most efficient fluorescent lamps available, using half of the energy of an office built just a few years ago. They operate on motion sensors so that lighting energy is not wasted when it is not needed.
|Heating and Cooling
The heating and cooling system is able to simultaneously and efficiently move heat and cold throughout the building as it is needed. Heating is provided using a third as much energy as most typical new office buildings.
Facilities have been implemented to capture rainwater, including storage tanks, pumps and filtration systems. The water is filtered and reused either in the building or for landscape irrigation. As a result, no municipal water is used during the summer rainy season.
| Low flow fittings
All water fixtures have been specified so that they are efficient in delivering water that is needed.
|Solar hot water
All of the energy used to heat hot water in this building is provided by the sun.
Bicycle racks are installed at the building entrance, and shower and locker facilities have been provided for cyclists. As the Sandton area densifies, it is expected that more people will commute by bicycle.
Lots of daylight makes for a better work environment and less need to using energy for electric lights. This makes for a healthier and more productive work environment.
| Fresh Air and Natural ventilation
Openable windows are featured to encourage natural ventilation of the building to reduce reliance on air conditioning. High volumes of fresh air are provided into the building to reduce the buildup of carbon dioxide and contaminants, maintaining great indoor air quality
Recycling waste storage areas are designated where waste is sorted before it is recycled.
| Material efficiency
Recycled steel and significantly less concrete are used in the construction of the building. This reduces the energy, mining and waste associated with producing the building materials.
| Sustainable Timber
More than half of the timber used in the construction has either been previously used, is recycled, or comes from a Forest Stewardship Council Certified Source. This reduces deforestation and encourages sustainable use of our natural resources.
