AFFIES SCHOOL BUILT IN THE 1920’S IS JUST ONE EXAMPLE OF MANY, OF THE ENDURING QUALITIES OF CLAY BRICK SANS 517 certification and the marketing speak of the proponents of light steel frame building. The structural integrity and look and feel (quality) of the five clay brick schools inspected was palpably superior, similar to that of the Bongolethu and Heideveld schools. As for thermal comfort, the efficiency with which insulated lightweight IBTs facilitate ‘hotbox’ indoor environments during summer days will further detract from the quality of the teaching and learning experience provided by lightweight IBTs. There was zero evidence to support Dr van Wyk’s general assertion that IBTs provide “improved energy efficiency and quality control” (Built - July 2014). If we are serious about sustainable infrastructure and job creation, as we should be, then fabricated or prefabricated, high maintenance, less energy efficient, limited lifecycle lightweight IBT buildings, as evidenced in these Agrément certificated and SANS 517 compliant system built schools referenced above, seems hardly a plausible approach for providing social LSF SCHOOL GAUTENG – SEPARATION BETWEEN AND CRACKING OF PANELS infrastructure buildings that should be built with a 100 year plus lifecycle in mind. Sustainable Building As highlighted in the Energetics full Life Cycle Assessment, today’s environmental paradigm requires we build buildings able to endure with little maintenance, and definitely no materials replacement, way beyond the 50 year life cycle. Clay brick buildings in all their forms have proven themselves over the centuries to be more than up to this task. Looking to a sustainable, energy efficient future, it may be considered most fortunate that the South African building industry has been founded on a masonry tradition that endures to this day; a simple, cost effective building methodology that science now proves so relevant for achieving a more sustainable future. Holistic Value The holistic sustainable value of clay brick construction, buoyed by the scientifically proven superior thermal outcomes double skin clay brick walls provide, simply amplifies the extent of the added value clay brick construction offers over alternative lightweight systems for building a more sustainable, more energy efficient future and keeping our world a better place. 14 Clay Brick
