A passive solar energy building for the University of La Pampa in Argentina.

During 1997, an energy efficient building was designed, featuring energy conservation, passive solar heating, natural cooling and daylighting strategies. It is located in the province of La Pampa, in the temperate semi-arid region of central Argentina. The resulting compact design houses takes 634m2 of useful floor area with main spaces. An audience class, two laboratories, four research offices, one simple class and services make up the building. Solar windows are provided for all main spaces, except in the audience class. Clestories contribute to add solar gains and natural lighting.

Indoor air quality in libraries in the University of La Coruna.

The CO2, H2O and CO content of the indoor and outdoor air in the four libraries of the University of La Coruiia (Spain) was monitored for 48 hours. For this a multipoint monitoring system was used, based on the infra-red photo-acoustic spectroscopy technique. This allowed us to identify the conditions of air renovation of indoor air with natural ventilation. Although good outdoors air quality was observed, the indoor air quality, on the other hand, was seem to deteriorate considerable during the periods of occupation.
