Abstract

Two main fields related to the climatic design of guestroom wings are here studied: (1) the climate and its influence on the thermal comfort of the human being, and (2) the design of hotel buildings according to their type, as well as their thermal comfort performance requirements.

Hotels are divided into two main groups as a function of the quality of service provided (1-2 and 3-5 star hotels) Following the determination of guests’ climatic needs according to activity and clothing, and the effect of the shaded (or not) window area on the mean radiant temperature, comfort is evaluated together with thermal insulation values for building elements.

Three design modules are suggested to represent guestrooms in Israel and abroad. With the aid of the “Total Thermal Time Constant” computerized method, a thermodynamic simulation experiment is done in order to evaluate the effect of several design variables on one chosen module’s thermal performance. Conclusions are drawn concerning building form and facades orientation, window size and glazing, shading levels, the heat capacity and thermal resistance of the envelope and internal building elements, cooling and heating patterns, etc.

General design guidelines and solutions to the whole country, as well as design guidelines specific to each climatic zone, are proposed. A building including a solar atrium lobby is schematically designed, among other architectural solutions, to suit Israeli climatic conditions. Shading strategies as a function of window orientation, and optimal window form and size according to sight-angles, are also suggested.
