环境空气设施.室内空气质量.人类用室内空气质量的表达方法

[中文适用范围]： 本国际标准旨在： - 规定适用于人类居住室内空气质量表达的方法； - 允许根据当地要求、约束和期望设定几种可接受的室内空气质量目标水平。 本国际标准适用于： - 新建筑及其系统的设计以及现有建筑及其系统的改造； - 主要关注人类居住者的室内环境； - 具有机械通风和自然通风组合的建筑； - 商业和公共建筑。 本国际标准不适用于住宅建筑、工业建筑和医院，尽管此类建筑中类似于商业建筑的部分包含在内。由于存在以下不确定性来源之一或多个，本国际标准的要求可能无法在所有建筑中为所有人提供可接受的室内空气质量。 - 带入建筑的室外空气可能不可接受，或可能未得到充分净化。 - 室内空气具有多种来源和污染物。 - 有许多因素影响居住者对室内空气质量（IAQ）的感知和接受度，如空气温度、湿度、噪音、气味、照明和心理压力。 - 人群中存在不同程度的敏感性和偏好。 [外文原描述]： ISO 16814:2008 is intended to specify methods to express the quality of indoor air suitable for human occupancy, to allow several acceptable target levels of indoor air quality, depending on local requirements, constraints and expectations. ISO 16814:2008 applies to the design of new buildings and their systems and the retrofit of existing buildings and systems, indoor environments where the major concern is that of human occupants, buildings having any combination of mechanical and natural ventilation, commercial and institutional buildings. ISO 16814:2008 does not apply to residential buildings, industrial buildings and hospitals although those parts of such buildings that are similar to commercial buildings are covered. The requirements of ISO 16814:2008 might not achieve acceptable IAQ for all people in all buildings, due to one or more of the following sources of uncertainty. The outdoor air brought into the building can be unacceptable or might not be adequately cleaned. Indoor air has a wide diversity of sources and contaminants. There are many factors that affect occupant perception and acceptance of IAQ, such as air temperature, humidity, noise, odours, lighting and psychological stress. There is a range of susceptibility and preference in the population.
