Saving energy in buildings

In recent years, many different claims have been made about reducing the cost of running an office building by installing some proprietary energy‐saving system or another. Yet, even where these claims have been advanced in good faith, they have usually been based solely upon theoretical calculations. Very rarely have they been based upon practical measurements of alternative systems in a full‐scale model which would satisfy the very demanding standards of a truly scientific experiment. Therefore the results drawn from Sulzer Brother's experimental building in Winter‐thur, Switzerland, are of particular importance to anyone concerned with building design and property management. For, one of the objects of constructing this building was to test in a real life example whether energy could be saved by integrating the design of the building with its services in a particular manner. Also, it was to provide a practical model in which alternative methods could be measured and evaluated.
