Objective and subjective measurements of office meeting rooms

This research is a preliminary investigation of the objective measurements ofthelmal comfort and C02 levels as well as subjective user evaluation surveys in six meeting rooms. The ongoing objective measurements were taken via thelmal comfort carts while the surveys evaluated parameters of temperature, lighting, air quality, meeting effectiveness etc. The outcomes are of particular interest since some of the objective measurements clearly to not support those of the users. In fact, the investigation has triggered off further interest in refining questionnaires to develop more precise indicators of 'discomfort'.<br>Furthelmore, meeting rooms present a challenge when it comes to conditioning spaces (HV AC design) which are sporadic in use and often with high occupancy for short periods. This paper investigates meeting rooms in four different buildings and their conditioning control concepts are discussed in relation to measured results.<br><br>
