Innovation in construction : experiences from a hypocaust system in Australia

Introducing new technologies poses a particular challenge to the players involved in a project. For a successful low energy building, a new design process is required and players must assume new and additional responsibilities. Hypocaust systems, where conditioned or non-conditioned air is passed through ducts within the concrete floor or ceiling of a building prior to its delivery to the rooms, are starting to appear in new buildings in Australia. This paper describes the lessons learned from the early experiences with a hypocaust system, installed in a new building in Melbourne. It concludes that a more cooperative process among all those involved in introducing and using a new 'technology' is essential if the problems described are to be avoided or at least minimized.
