Seminar on passive architectural heating and cooling.
Prof Norbert Lechner
Passive solar heating and cooling are only two of the many strategies that make up solar responsive design, which includes not only the gathering of solar energy for heating, lighting, and the generation of electricity, but also the rejection of the sun’s energy through shading and the use of light colors.
The quickest and best way to move toward sustainability is to “pick the low hanging fruit first” which means using the easy and low cost strategies before the difficult and expensive ones. Thus, the following solar responsive design strategies should be in a design in the following order: orientation, form, color, window size/placement, shading, daylighting, active solar ventilation preheating, active solar hot water heating, and finally photovoltaics.
In a similar manner, passive cooling is achieved by first picking the “low hanging fruit” of heat avoidance. For example, by using efficient appliances and electric lighting less energy is turned into heating the indoors. Furthermore, more heat can be avoided by using daylighting, shading, and the use of light colors.

The main aim of the presentation is to introduce the active systems in buildings for controlling environmental factors and to make aware of the inevitable collaboration between architects and engineers in building design and construction process. Framework of this presentation link up significant competences, guidelines and rules of thumb based on accumulated practical experience.
