Natural ventilation in atria
- Danish Building Research Inst., Hoersholm (Denmark). Energy and Indoor Climate Div.
Natural ventilation by thermal buoyancy and wind is very suitable for the ventilation of atria, provided the geometry and the openings are well designed to fulfill required ventilation rates and control needs. This paper presents a set of formulas for determining air velocities, temperature differences, and ventilation capacity in relation to openings, heat loads, and building geometry. Optimal opening areas, the influence of temperature stratification, threshold values for the opening ratios, as well as control strategies are discussed. The set of formulas constitutes an easy-to-use design method that can be programmed as an independent computer program or be integrated into a simplified building energy simulation program.
