Quantification methods of natural ventilated building performance in preliminary design

ABSTRACT

Natural ventilation can reduce the operational energy consumption of buildings in an energy-saving, environment-friendly and wholesome manner. This paper uses the existing ISO-standardized energy performance calculator and incorporates a dedicated controllable ventilation model to develop a method for the early design assessment of natural-ventilation-driven cooling with the aim of providing a technical support for studying the goal- and performance-oriented design of buildings adaptable to the regional climate. To facilitate application by architects, the normative model applies a certain degree of simplification, requiring only a small set of macroidentifiers for the considered building and assuming generic ventilation provisions in terms of the window opening size and control logic.
