Examines a new energy conservation technique based on the control of the "fresh air intake" through measurement of CO2 content in extracted air for different kinds of buildings. Assesses various techniques for measuring CO2 concentration in view to design a low cost sensor, concludes that theinfra-red absorption technique is the most suitable. Shows through computer simulation that a CO2 based ventilation system can provide a better pay-back period than an air-to-air heat exchanger. Enquiries to European CO2 sensor manufacturers show that CO2 appliances can be designed and sold at about 200 dollars each.
