Enhance thermal control of building occupants through the provision of thermal zones. <\/p>","intervention":"
This WELL feature requires projects to increase thermal control of the space, by allowing control of either the conditions of a thermal zone or movement between thermal zones.<\/p>","issue":"

People in buildings who are satisfied with their thermal environment have been shown to be more productive in the workplace.1,2<\/sup> For instance, employees perform on average 15% poorer in hot conditions and on average 14% poorer in cold conditions.3<\/sup> An average 2% decrease in work performance per {{well-unit}}1.8 °F|1 °C{{\/well-unit}} of air temperature rise has been found, when the air temperature is above {{well-unit}}77 °F|25 °C{{\/well-unit}}.4<\/sup> On the other hand, even a {{well-unit}}1.8 °F|1 °C{{\/well-unit}} decrease in air temperature within the range of {{well-unit}}68 °F|20 °C{{\/well-unit}}-{{well-unit}}77 °F|25 °C{{\/well-unit}} is linked to increased student performance in mathematics.5 <\/sup>Furthermore, thermal comfort preferences are highly individual and can be affected by metabolism, body type, clothing and other personal factors.6–8<\/sup> These personalized factors make it nearly impossible to find a temperature that will satisfy all individuals in the same space at the same time.9<\/sup><\/p>\r\n\r\n <\/p>","evidence":" Indoor air temperature can be influenced by a number of factors, including the building physics and orientation, building location and structure, occupant density, ventilation strategy and mode of operation. In the majority of buildings, the HVAC system is responsible for controlling indoor air temperature and humidity. Where temperature zoning is an option, individually controllable thermostats that enable people to set their own thermal conditions independently of other zones should be used.<\/p>","implementation":null,"impact":null,"max_points":2,"concept_id":1738,"slug":"thermal-zoning-1","gbd_exists":0,"review_summary":null,"citations":" The following requirements are met for at least 90% of regularly occupied spaces:<\/p>","description_alt":null,"space_property":null,"certification":null,"note":null,"sub_part_id":33045,"deleted_at":null,"note_position_override":"top","verification_note":" Mechanical drawings<\/p>","verification_condition":"AND","requirements":[{"id":120585,"option_id":41967,"requirement_order":1,"description":" Control over temperature in the space is available through either:<\/p>\r\n\r\n 1.
