Concern & action: Default settings
Default settings control the normal operation of services. They can be adjusted for season and occupation patterns. They need to make sense for energy saving but also for the users. A misalignment could mean wasting energy, discomfort and/or ill health.
Understand energy use profile for building type (dwelling, office, school etc.) and determine occupancy patterns. Define seasonal (winter, spring, summer and autumn) and daily patterns (how many hours of occupation?). Understand user needs and preferences. Discuss with users settings for energy efficient use of the technology and agree settings (seasonal and daily) that make sense for the user comfort, health and energy efficiency.
Talk to supplier of controls to ensure desired control pattern is possible. Choose controls that are easy to operate and engage the user in their choice.
Check settings after installation of controls and show user how to control settings - hands on demonstration. Determine typical and good practice levels of energy consumption. Engage and make recommendations to user with regards settings for energy saving and for health. Monitor energy use after implementation of measures, make this information available to occupants and report results, making recommendations on settings adjustments if needed.
