近年来，大多数多户住宅建筑通过自然通风满足了居住单元的通风要求，并且没有提供额外的机械通风方式。ASHRAE标准62.1、62.2的变更，以及这些变更在当地法规中的采用，要求多户住宅单元采用机械通风。本文评估了可满足规范强制机械通风要求的系统和设备，并讨论了选择对建筑的影响。评估的影响领域包括建筑美学、资本成本、年度能源成本、公用事业计费结构、建筑空间要求、系统和设备维护，以及绿色建筑评级影响。在适当的情况下，建筑尺寸的影响将包括在评估中。毫不奇怪，最终机械通气系统的选择是一个权衡的过程。例如，分布式通风系统可能不需要建筑核心的竖井空间，但需要建筑立面的百叶窗。 为通风和排气系统提供能量回收可降低年度能源成本，但增加建筑资本成本。因此，不能提供单一的建议，因为每栋建筑不仅在物理上不同，而且业主的要求、资金结构和绿色评级系统的影响可能会改变适当的系统选择。在设计和施工过程中，两栋建筑似乎有着相同的约束条件，这两栋建筑可能是由两套非常不同的业主要求驱动的，因此使用了非常不同的方法为住宅单元提供机械通风。引文:2017年冬季会议，内华达州拉斯维加斯，会议论文

In recent years the majority of multi-family residential buildings have satisfied the ventilation requirements of the dwelling units via natural ventilationand have not provided an additional means of mechanical ventilation. Changes to ASHRAE Standard 62.1, Standard 62.2, and the adoption of thosechanges into local codes require multi-family dwelling units to be mechanically ventilated. This paper evaluates systems and equipment available to meetthe code mandated mechanical ventilation requirements and discusses the impacts of the selection on the building. Areas of impact evaluated are buildingaesthetics, capital cost, annual energy cost, utility billing structure, building space requirements, systems and equipment maintenance, and greenconstruction rating impact. When appropriate, the impact of building size is included in the evaluation. Not surprisingly, final mechanical ventilationsystem selection is a process of evaluating tradeoffs. For instance, distributed ventilation systems may not require shaft space in the building core butwould require louvers in the building facade. Providing energy recovery for the ventilation and exhaust systems reduces annual energy cost but increasesbuilding capital cost. As a result, a single recommendation cannot be provided as every building is not only physically different but the owner'srequirements, the funding structure, and impacts of a green rating system may change the appropriate system selection. Two buildings that would appearto have identical constraints after the fact may have been driven by two very different sets of owner requirements during design and construction and as aresult use very different approaches to provide mechanical ventilation to the dwelling units.
