Abstract
ASHRAE Standard defines naturally conditioned spaces as those where thermal
conditions are regulated primarily by the occupants through opening and closing of the
windows. It is known that non-domestic naturally ventilated buildings are likely to
consume less energy than those that are air-conditioned which is related with the fact that
this ambiences tend to make more effective use of natural light and partly because the
electrical energy consume by fans, chillers and pumps is avoided. In this sense, naturally
ventilated buildings can have low energy demands but the strategy is difficult to implement
in urban locations. Present paper shows a practical case study about indoor condition in
typical Spanish library respect ASHRAE indications. Results showed temperature and
relative humidity values higher than expected. In consequence a higher percentage of
dissatisfied and materials deterioration was found. Passive climate control methods were
proposed to get a sustainable building.
Keywords: ASHRAE, humid climate, materials preservation.
