dow in their office allows workers to adapt to and tolerate temperatures outside the comfort zone in a sealed building environment. Strategies for improving thermal comfort, lighting, and acoustics in indoor environments include these suggestions: • Use daylighting. Design the building to provide ample access to natural daylight and views for the occupants. Service areas, equipment rooms, closets, and locker rooms should be located in the building core, with regularly occupied spaces placed around the perimeter of the building. • Install operable windows. If possible, provide windows that can be opened to the outside. • Give occupants temperature control. In mechanically ventilated buildings, provide thermostats that allow occupants to control the temperature in their immediate environment. • Give occupants venti lation control. In mechan ically ventilated buildings, provide adjustable air diffusers that allow occupants to adjust the airflow in their immediate environment. • Give occupants lighting control. Provide occupants with adjustable lighting controls so that they can match the lighting levels to their tasks. • Conduct occupant surveys. Use valid survey protocols to assess occupants' satisfaction with the indoor environment. Make operational changes based on the feedback. THINK ABOUT IT Thermal comfort. Experiments to determine thermal comfort norms for humans have been performed in carefully controlled laboratory environments where people were subjected to various environmental conditions. The standards developed through this research advised designers and operators to keep building environments within strictly defined ranges . However, recent research in real-world situations has shown that people are tolerant of more varied conditions when they have control over their environment. What are the energy efficiency implications of design that accommodate personal control over one's environment Primary Resources: Daylig hting A study of more than 2,000 California classrooms found that students in classrooms with the most daylight progressed 20% faster in math and 26% faster in reading than students in the classrooms with the least amount of natural light. 62 Green Building and LEEO Core Concepts Guide

Indoor Environmental Qu ality Studies by the Center for the Built Environment at the University of Californ ia-Berkeley have found that occupants of green buildings report significantly greater satisfaction with indoor air quality t~ a n occupants of conventional buildings. However, the benefits of green building don't extend to all aspects of indoor environmental quality. The green buildings often had superior air qualitY but provided less satisfaction in measures of acoustic quality. • Indoor Environment Department, Lawrence Berkeley National Laboratory, htto;//eetd.
