I have just read an article by Mathew Hardy about the principles shared by traditional buildings. New buildings should incorporate what we have learnt from traditional buildings. These have stood the test of time and can be said to be truly sustainable. How were buildings made when people had to build their own homes with only local resources at their disposal. As Hardy says we are about to enter a time of shortages. In fact many areas of the world are already experiencing this. This is something we share with the past. These buildings have a lot to teach us.
The principles are
1. Closed |Building Energy Cycle
2. Use Local Materials
3.Build Up, Don’t dig down – that is sit the buildings as far as possible on the natural slope
4. Timber and wood
5.Maximum Volume Minimum Surface Area: enclose the maximum possible volume using the minimum of materials thus minimising surface area.
6. Build to Enclose Open Space
7.Finishes Reflect the Use of the Rooms
8. Make 16 foot or 5,5 m rooms – relates to the size of timbers
9.Shed the rain and make a usable loft – this is the most important element of a building. You need to create usable roof spaces while minamising both eaves height and the number of junctions in the roof plane itself
10.Animals Below and Hay Above – and other strange strategies
11.Build for Cyclical Maintenance and Repair – traditional materials are not necessarily highly durable but local economies supported through maintenance rituals of renewal.
12.Only Heat the Key Spaces – additional heat from warm clothes and/or animals
