Methodology for analysis and decision making by sampling in buildings

Abstract

(English) The sampling of the users comfort, allows observing and predicting the level of comfort on the HVAC system. The development of online sampling systems assists in the recognition of the behaviour patterns that occur in the offices. This paper presents a methodology specially designed and developed in order to make easier knowledge extraction and representation, in this way it possible to make decisions about the comfort in buildings. The methodology used provides important and useful information to select the comfort set-point of the rooms of a central HVAC system without the need to use fixed values based on programmed time schedules or any other methodology. In this methodology, the users are evaluated by using a standard set of key questions in order to measure the level of satisfaction respect to environmental factors, thanks to a questionnaire of imprecise answers. We seek an improvement in the building users, regardless of their particularities.
