Thermal Performance of a House with Ventilated Wall Z. Zhuang* , J.Y. Ying

Abstract

This paper proposes the use of a heavy ventilated wall to store natural energy and improve heating performance. An ideal numerical model was setup, and the thermal performance and annual heating contribution under different heating power, building insulation, airtightness and climates were explored by case studies. It is found that the ventilated wall with heat source has the potentials for creating a stable thermal environment, and also contributes to reducing building heating load. The initial findings can help engineers to develop design proposals for building envelops with an active heat source at the early design stage.
