IE Q Credit 6.2: Controllability of Systems—Thermal Comfort
1 Point

Intent
To provide a high level of thermal comfort system control1 by individual occupants or groups in multi-occupant
spaces (e.g., classrooms or conference areas) and promote their productivity, comfort and well-being.

Requirements
Provide individual comfort controls for 50% (minimum) of the building occupants to enable adjustments to meet individual needs and preferences. Operable windows may be used in lieu of controls for occupants located 20 feet inside and 10 feet to either side of the operable part of a window. The areas of operable window must meet the requirements of ASHRAE Standard 62.1-2007 paragraph 5.1 Natural Ventilation (with errata but without addenda2). Provide comfort system controls for all shared multi-occupant spaces to enable adjustments that meet group needs and preferences.
Conditions for thermal comfort are described in ASHRAE Standard 55-2004 (with errata but without addenda2) and include the primary factors of air temperature, radiant temperature, air speed and humidity.

Potential Technologies & Strategies
Design the building and systems with comfort controls to allow adjustments to suit individual needs or those
of groups in shared spaces. ASHRAE Standard 55-2004 (with errata but without addenda2) identifies the factors of thermal comfort and a process for developing comfort criteria for building spaces that suit the needs of the occupants involved in their daily activities. Control strategies can be developed to expand on the comfort criteria and enable individuals to make adjustments to suit their needs and preferences. These strategies may involve system designs incorporating operable windows, hybrid systems integrating operable windows and mechanical systems, or mechanical systems alone. Individual adjustments may involve individual thermostat controls, local diffusers at floor, desk or overhead levels, control of individual radiant panels or other means integrated into the overall building, thermal comfort systems and energy systems design. Designers should evaluate the closely tied interactions between thermal comfort as required by ASHRAE Standard 55-2004 (with errata but without addenda2) and acceptable indoor air quality as required by ASHRAE Standard 62.1-2007 (with errata but without addenda2), whether natural or mechanical ventilation.

IEQ C6.2: 系统可控性—热舒适度
1分

目的
设置高等级的热舒适度系统控制1，可由单个控制或多人空间(如教室、会议室)的团体控制促
进健康、舒适和工作效率。

要求
为建筑用户的至少50%提供可调节的热舒适度单个控制，来满足个体要求。可开启窗可被视为
用户的控制手段，凡距外墙20英尺内，距窗可开启部分10英尺以内的用户都算是。窗的可开启
面积必须复合ASHRAE 62.1-2007第5.1款“自然通风”的要求。
对多人使用的共用空间，提供舒适度系统控制，可根据其需要进行调节。
热舒适度条件由ASHRAE 55-2004确定，包括了空气温度、辐射温度和空气速度、湿度基本参
数。

技术措施和策略
建筑系统设计时提供热舒适度控制系统，以使单体或共用空间的团体根据需要进行调节。标准
ASHRAE 55-2004给出了热舒适度的参数和一个有关于建筑用户日常活动所设计适合热舒适度
的处理过程。控制措施用于扩展这些舒适度范围，使得用户根据其需要进行调节。这些措施和
结合可开启窗进行系统设计，混合系统集成了可开启窗和机械系统、或者只有机械系统。单个
调节可以采用单个温度控制器、地板(桌面、顶部)散风装置、单个辐射板控制或其他集成在建
筑系统、能源系统中的控制。设计者应评估由ASHRAE 55-2004给出的热舒适标准，和标准
ASHRAE 62.1-2007所给出的室内空气质量要求的相互自用，无论是对机械通风，还是自然通
风。
