The objective of this study is to find simple, non-computerized, tools to be used by designer during the initial design stages, in order to obtain a climatically “correct” building, saving a maximum of exhaustible energy while at the same time maintaining comfortable interior thermal conditions.

The study was carried out in stages as follows:

Stage A - A literature survey on research and development in the field of climatic comfort. The result of this stage was an integrated graph recommending a climatic comfort range and design strategies to be followed in improving climatic conditions in the building to be designed.

Stage B - The main part of the study, consisting of a systematic examination and analysis of the effects of various parameters (geometry, orientation, insulation, ventilation est.) on the climatic conditions created in the building and on the energy required to improve these conditions so as to satisfy the users. The examination was conducted on standard apartments in various floors of buildings in climatic zone B, according to Israeli Standard 1045. Climatic data was obtained for two locations: Ramat David and Beer Sheva. The analysis was carried out on the simulation model ENERGY developed by Shaviv and Shaviv (1977-78).

Stage C - Conclusions, based on the results obtained from the simulation model. The end result of the research is a designer’s handbook consisting of an examination of the various parameters and weighting their degree of significance, design recommendations and “rules of thumb”, to be used by the designer.

Similarities and differences were discussed, not only of the Ramat David and

Beer Sheva results, but also of a similar analysis made using data from Tel Aviv and Jerusalem in previous study (Shaviv and Capeluto, 1992).

The tools developed in the present research will facilitate the designer’s work during the pre-conceptual the conceptual stages, when he is engaged in gathering data and analyzing design strategies which will lead to a climatically Correct” design.
