Recently I went to educate myself on the rational design method of achieving compliance in terms of the SANS 10400-XA building regulations. I am proud to announce that Wilh+co can now offer this method of certification which leads to much better results with regards to the amount of affordable glazing we can use in buildings. With the calculation methods prescribed by the new building regulations we have been force to make our buildings with the large windows that we have been so used to in South Africa unnecessarily expensive to achieve compliance. Rational design gives us the opportunity to prove that good design will prevail. I am over the moon with the results and the peace of mind that finally our design style is proven to deliver excellent thermal control results.
We now have the tools and knowledge to reduce the fenestration specifications significantly on our buildings. On the first project we have implemented our new calculation method we have managed to save our client R150,000.00 plus on the reduced specification for the windows. Even skylights have made a comeback all within the bounds of the new SANS 10400-XA building regulations. The excitement abounds: we are taking the light back!
