MacroFlo is a program for analysing infiltration and natural ventilation in buildings. It uses a zonal airflow model to calculate bulk air movement in and through the building, driven by wind

Demonstrate how to reduce the need for air conditioning using natural / mixed-mode strategies. Analyse all aspects of bulk airflow: infiltration, natural ventilation, facade design, mechanical ventilation. Simulate air flow processes over different periods – …

MacroFlo is a simulation program for the design and appraisal of naturally ventilated and mixed-mode buildings. MacroFlo runs as an adjunct to APsim, exchanging data at run-time to achieve a fully integrated simulation of air and thermal exchanges. MacroFlo simulates the flow of air through openings in the building envelope.

MacroFlo. Flow of air throughout a building, and the movement of heat or coolth, impacts building performance greatly. Airflow is influenced by a number of natural and mechanical means and the interaction of HVAC systems forced air movement with naturally occurring airflow is an essential pre-requisite to accurate simulation of energy usage.

本篇文章以IESVE软件的自然通风模块MacroFlo来引领设计者快速对我们的目标建筑物进行自然通风模拟（渗透风、整体建筑自然通风、ApacheHVAC耦合混合模式通风等），以达到优化建筑物整体造型和减少能耗的目的。

MacroFlo provides a default selection of pressure / flow characteristics for a wide range of opening types for the convenience of the <VE> user. Holes represent a special category of opening with constant and un-modifiable air flow characteristics, and …
