This paper reports on test house measurements and simulated prediction for the proposed passive air-circulation
system on brick houses. A test house was constructed to validate experimentally the effect of passive device
elements. Direct solar gain and Trombe Wall effect are the object in winter in terms of passive heat gain. Earth
cool tubes and solar chimney effect by Trombe Wall are measured to estimate the passive-cooling amount.
Operation schedule and air-circulating route are varied to obtain the maximum effect of the air-circulation
system. The thermal performance of a newly designed brick house is simulated as the second part of this paper.
Experimental results on the test house are used to validate the accuracy and feasibility of the simulation
programs. Distribution of thermal mass, arrangement of heat gain/exhaust elements, combination of other
passive devices and operation scheme are the key factors to be estimated for the optimisation of thermal
environment design in brick houses with passive systems.
