Optimal Thermal Environment

• Radiant temperature where surface and air
  temperatures are balanced,
• Air temperature between 64 and 72 F,
• Humidity between 40 and 60 percent, and
• A constant air movement of 20 to 40 lineal
  feet/per/minute at a sitting height.

9
Energy Management Process

• Assessment of the building and operating systems.
• List of appropriate energy conservation measures
  based on assessment.
• Careful planned implementation.
• Regular review of actual energy savings.

13
Steps to Improve Water Conservation

• Shut off taps fully
• Repair drips and leaks promptly
• Check timing cycles for automatic systems
• Install low-flow aerators
• Retrofit toilets

14
Steps to Reduce Outdoor Water Consumption

• Plant only native vegetation suited to climate
• Limit watering of turf
• Water only during evening and overnight to reduce
  evaporation
• Use trickle or soaker hoses
• Design for runoff rainwater to return to the soil
