Glazing configuration and performance, Solar management
Operational: Building Features
• Features that can be delivered/required in the construction contract/process – Acceptance Testing (incl., economizers, controls, feedback
systems etc) – Infiltration Testing/Air Barrier Commissioning – Metering/Meterability – Equipment Fault Detection and Diagnostics (FDD)
Capabilities – Operations/User Manual – Updated OPR – Operations guide – Maintenance schedule – As-Built Drawings
Operational: Hand Off
• Initiation and Training to start building operation on the right track
– Owner Orientation
– Operator Training
– Metering and Feedback Plan
– Equipment Purchase Standards for Fit-out
– Occupant Training
– Maintenance Plan
Operational: On Going Performance
• Utility Role in maintaining long-term building operation – Resource Conservation Manager – Tenant engagement – Plug Load Management – Retro Commissioning Plan – Performance Data Review – Equipment purchase guidelines – On-going operator training/support – Disclosure – Operator feedback – Tenant feedback – Public feedback

Core Performance Components
• Core Performance 2.0
• CP 1.1
• IECC Supplement
• Multi-measure tool
Implementation Perspective
• How Core Performance’s comprehensive
concept influenced my thinking
• How that impacted energy savings (kWh
and Therms)
• How it translated within the organization
• How this concept raised the level of
awareness in the design community.

The NBI Influence
The concept of integrated projects
changed my approach from being
“widget” based approach to one
that’s more comprehensive

New Construction Program Effects:
• Greater energy savings
• Lower cost/less staffing per project
• Better targeting (approach to market)
• Impacted all building in service territory
• Helped raise local design practices

What Happens to Programs When State and Local Energy Code Increases?
• IOU Program administrators could receive credit for some energy savings from code
• Program administrator in an excellent position to support with training
• NBI committed to developing the next generation approach – IgCC, 2015 IECC, 2013 Mass. Stretch – so program continues with advancement in codes
Utility Support to Implement Reach Codes and Programs
• Technical assistance, participate in energy committees • Trainings, education (sharing resources with state, including
Estar) • 3rd party inspections support for compliance (HERS for
residential and develop new ‘reach code inspectors’ for commercial)
• Involvement in development of next round of reach codes • Incentives to projects for meeting reach codes till they become the
baseline code (program design parameters) • Issues with attribution – determined locally with national guidance
and support – NBI papers and EM&V Forum
Code Adoption is Driving Core Performance 2 Development Schedule
