Rules of thumb for preliminary design can be ascertained from a qualitative examination of the governing equations of flow, which elucidate the relationships between ‘core’ variables – flow rates, air temperatures, heat inputs and building geometry. Finally, the impact of the window type on the performance of single-sided natural ventilation is assessed.Ī simple mathematical model of stack ventilation flows in multi-compartment buildings is developed with a view to providing an intuitive understanding of the physical processes governing the movement of air and heat through naturally ventilated buildings. The comfort level of non-air-conditioned buildings is then studied for each building case. For each building case, the energy-saving potential of a mixed-mode cooling system is analysed compared with the same building case with a full air-conditioning system. Several cases of office buildings are assessed, taking into account the main factors influencing the natural ventilation potential such as building loads, thermal inertia and orientation. The methodology is based on the use of a building energy simulation program coupled with a recently developed correlation for single-sided ventilation. Then, the performance of single-sided natural ventilation is assessed for low-energy office buildings in two European climates. This article intends to review the techniques of single-sided natural ventilation and the tools available to assess the performance of this technique. Indeed, the cooling effect of this technique driven by wind and stack effects is highly dependent on outdoor conditions. However, this technique is often ruled out by building designers since its ability to maintain comfort conditions is difficult to assess. Single-sided natural ventilation is a free cooling solution which accommodates readily to most office building layouts. The market will decide the immediate value of such features, but ASHRAE may wish to consider related modifications to the standard in the future. Some of these systems go beyond the current standard by providing additional features (such as air distribution or pressurization control). While these systems generally fall into the categories of supply, exhaust, or balanced, the specifics of each system are driven by concerns that extend beyond those in the standard and are discussed. This report describes a wide variety of systems currently on the market that can be used to meet ASHRAE Standard 62.2-2004, Ventilation and Acceptable Indoor Air Quality in Low-Rise Residential Buildings. The paper also examines related issues, such as infiltration, duct systems, filtration options, noise, and construction issues. Key parameters that are related to each system include operating costs, installation costs, ventilation rates, and heat recovery potential. The major technologies reviewed include a variety of mechanical systems, natural ventilation, and passive ventilation.
