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
