Research Questions

How does actual energy performance compare to predicted and baseline energy performance metrics?
What is the current indoor environmental quality (IEQ) state and how does this vary between different types of spaces and occupancy characteristics?
How are the current building occupants affected by the IEQ and energy performance characteristics of this building in terms of satisfaction, comfort, appraisal, well-being, and energy behaviors?
What strategies can be used to increase occupant awareness of the building’s energy performance and IEQ?
What strategies can be used to improve energy outcomes of occupant behaviors?

Data Collected

A multiple-research methods approach was utilized to gather a range of data regarding the building’s energy and IEQ performance and characteristics over an 18-month period following initial occupancy of the building (12-months following full occupancy of the building). A comprehensive post-occupancy evaluation (POE) survey instrument was utilized to gather baseline data regarding the occupants’ satisfaction, comfort, appraisal, well-being, and energy behaviors at the end of the 18-month period following initial occupancy of the building. A follow-up survey was distributed 6 months after the baseline survey, during which time a number of strategies to increase occupant awareness and improve energy outcomes due to occupant behaviors were examined in quasi-experimental settings (not included in this document). Energy data was continuously monitored throughout the entire study period outlined above (initial 18 month occupancy period, 6 month quasi-experimental phase, and follow-up survey phase).

IEQ Assessment

EQ measures were assessed over a 12 month period covering the first year of full building occupancy. IEQ field assessments were conducted seasonally in each target space and assessments were conducted in the morning (around 10 AM solar time) and in the afternoon (around 2 PM solar time) for each seasonal study. Target spaces were chosen according to the range of spaces within the building and researcher accessibility in order to capture data covering the array of different spatial use types and spatial locations within the building. IEQ measures were also gathered for all four floors of the Lorey I. Lokey atrium during each seasonal study.

The following data was collected for each target study space during each seasonal study.

• Indoor temperature and relative humidity
• 2 week period including 10 working days and 6 weekend days (no holidays were included)
• 3-4 HOBO dataloggers per space, located at 6’-8’ AFF.
• 3 exterior dataloggers (on the exterior surface of the building along the North, East, and South)
• Interior daylight illuminance distribution & intensity
• 3D illuminance measurements at occupants’ workspaces (visual asymmetry)
• High Dynamic Range Imagery (HDRI) of daylit interior spaces
• Infrared (IR) imagery of interior surfaces seen in HDRI imaging
• Direct observation of physical traces and environmental modifications
