• Waterfront Project designed and built following the Green
WATERFRONT PROJECT – CANAL SITE
Globes rating system – target five out of five Globes
• Tendered design utilized traditional methodologies for building automation, lighting control and IT
• After tender opportunities to move to a more intelligent building were identified (by Delta and Cisco) and initiated
• Canal Building full operation September 2011
• Target five out of five Green Globes rating for operations

TECHNOLOGY
Power over Ethernet Controllers (PoE)
•Network is installed by the Computing Services group
•Controller receives power from the Ethernet cable
•Installed and operated by Computing Services
•Computing Services provides the PoE switches
Lessons Learned
l ll f d•Earlier installation of IT equipment required
•IT installation moves to the critical path for the substantial completion of the building
•Need a strong team effort between the Computing Services group and the Controls contractor

Design and Performance MetricsASHRAE 90 1 E S d d f B ildi
PERFORMANCE METRICS
• ASHRAE 90.1 – Energy Standard for Buildings
• ASHRAE 189.1 – Standard for the Design of High‐Performance Green Buildings
• ASHRAE 62.1 – Ventilation Standard
• Guideline – 32
ASHRAE 189.1 – High Performance Energy Standard
PERFORMANCE METRICS
Standard• Goes beyond Std. 90.1 to cover additions areas
• Site sustainability• Water use efficiency• Energy efficiency• IEQ, and impact on atmosphere,
materials and resources• Highlights include:
• A ‘consumption management system’ where data is collected and stored

ASHRAE 189.1 – High Performance Energy Standard
PERFORMANCE METRICS
Standard• Add utility sub‐meter “to provide daily data and
record hourly energy profiles”• “capable of sorting the data and creating user
reports”
