INDOOR AIR QUALITY BEHAVIOUR

research? We have identifi ed the following 10 high priority research topics: Are the combined effects of temperature and IAQ additive?
Q
How does performance vary with self- estimated perfor mance?
Which component skills are affected by indoor tempera ture and air quality effects?
Is high-level work involving decision- making and creative thinking similarly affected?
Are leisure activities negatively affected by poor IEQ?
Is sleep affected by temperature and IAQ, and if so, does this affect next-day performance?
What is the economic impact of all these effects on differ ent kinds of productivity?
What is the most cost-effective way to reduce the negative effects of poor IEQ?
How can energy be conserved without affecting perfor mance?
How do energy certifi cation schemes affect productivity?
We believe that that the following four topics should be ad dressed by future research: Do thermal and IAQ effects on acidosis
Q
de crease performance? Is acidosis caused by shallow breathing or
by decreased gas exchange in the lungs? Which gas-phase indoor air pollutants
have this effect, and can it be prevented? Are any other mechanisms involved? CJ

What are the most commercially im portant questions for future
TO CONSERVE ENERGY IN BUILDINGS?
Short-term effects of poor air quality on the performance of schoolwork remained after airborne dust had been removed, so the negative effects observed were attrib uted to gas-phase air pollutants.15
