“I see it as an on-going experiment,” says Brian van Niekerk, the homeowner and managing director of the Rhino Group of Companies who have been responsible for the systems and integration of some of the building design. An intricate system of rainwater harvesting from all the roof areas as well as the front parking area via a hydromedia system allows water to drain through and get captured below before being pre filtered to join the water from the roof area and stored in 30 000 litre storage tanks in the utility room. The water is then pumped and treated via a number of filters including Ultra-filtration and UV creating high quality potable water for the home. A secondary filtration system has also been implemented, where all black water, along with organic kitchen and garden waste, is fed through an Agama biogas digester. The natural gas produced from this process is used for cooking and delivers enough gas for four hours’ of cooking time per day. The grey water meets up with the black water after the biodigester where it then is treated through a trickle filter and a further reed bed system. Thereafter in the utility room, the water goes through a number of filtering stages before being re-used for toilet flush back to the home, irrigation for the garden and top up for the aqua-gardens.The aqua-gardens all form a part of the swimming pool filtration, providing a natural eco system and chemical free swimming pool that circulates 24 hours a day.Finally the extensive use of recycled materials included in the decking, natural rock features, cupboards and counters made from shutter board and concrete baths, basins, polished concrete flooring and counter-tops ensure the house retains its sustainable feel. House Rhino is an autonomous, functional and modern family home that not only applies sustainability at a whole new level but also successfully shows that building an entire environmentally friendly home, as opposed to with some sustainability solutions, is both possible and affordable. www.rhinoplastics.co.za 35 INTEREST PIECE in the bar room and the air conditioner. In summer, cooling of the house is achieved through a thermal tower that extracts warm air via the highest point passively, as well as through cross ventilation via doors and windows strategically placed. The aqua-gardens also aids the process, providing cool humid air inflow as well as a high pressure fogging system atomising water droplets down to 10 microns around all the veranda areas, thus creating evaporative cooling.
