## Calibrated vs. Benchmark

- Efficiency

- Energy Star Score

- Exceed Title 24

## Delta Score vs % Savings

## Advanced Building Guidelines

- E-BenchmarkTM
- National beyond-code criteria
- Best Practices Manual
- How to from design team perspective
- Owners Guide
- What are the benefits to building to the E-Benchmark?

*Focus on Delivering Performance*

## E-BenchmarkTM

- Nationally recognized efficiency targets
- Envelope
- Mechanical
- Lighting
- Power (demand and renewables)
- Exemplar Processes
- Integrated Design
- Commissioning
- Operations/Maintenance
- Two Approaches
- Prescriptive “patterns”
- Whole-building simulation

## Development Process

- ANSI Procedure
- Committee Balance
- Public Review Process
- Committee Participation
- Face-to-face
- Conference Calls
- Schedule
- September 02 Draft
- Chicago Review (October)
- February 03 Draft
- Atlanta Review (March)
- NBI Board Review
- Washington, DC (May)
- Publish
- July 2003

## Example - Envelope

- DOE Proposed Climate Regions
- Opaque and Fenestration
- Indoor Environmental Quality
- Infiltration control
- Moisture control

## Example - Mechanical

- Equipment Efficiency
- Typically EPA, CEE Tier 2, or best utility program levels
- ASD’s on single chillers and fans/pumps > 10 hp
- Systems
- Sizing at multiple loads

## Example - Lighting

- IESNA Models
- New Technologies
- Super T-8
- Ceramic Metal Halide
- Controls
- Daylighting controls optional “credit”D

## Design Process

## E-Benchmark Process

- Pre-design Certification
- Statement of goals and principles
- Design Process Certification
- Statement of Intent
- Final plans/specs/Cx Plan
- Construction Certification
- Submittal/Cx Report
- Operations Certification
- Trend-log/Warranty
- Performance Certification
- Measurement and Verification

## Impacts

- Ventilation and Productivity
- $154 to $280 per employee (CMU-BIDS)
- Direct result of explicit process requirements
- Costs
- Ranges from $0.75 to $1.40/sf with supermarket up to $3.50/sf including commissioning
- Savings
- Ranges from $0.20 to $0.80/sf  with schools $0.10 to $0.15/sf
- Electric savings at 4 to 8 kWh/sf
- Ventilation benefits not included in cost savings
- Avoided Costs
- $0.01 to $0.03/kWh with schools up to $0.07

## Best Practices Manual

- Modeled after:
- Volume II: Design Guide
- Expanded to include:
- Other building types
- Design process oriented
- National climates
- Regional case studies
- Energy focus

## Owners Guide

- Assist in “selling” high-performance buildings
- Speak to this audience in terms they understand
- Example
- Daylighting is not a wall of view glass -- it is daylight filtered through glass that creates a soft, diffuse light that moves throughout the day without heat or glare.

## Influence

- ASHRAE
- Currently negotiating a co-sponsorship agreement between NBI, ASHRAE, IESNA and US DOE
- US EPA
- Will use E-Benchmark criteria as reference efficiency levels
- US Green Building Council
- Support development of a E-Benchmark/ LEEDTM user guide
- FEMP
- Reviewing for possible procurement standard
- NAIMA
- Referencing E-Benchmark insulation requirements in new guidebook

## Connections

- LEED
- Energy and Atmosphere Points
- New Construction Programs
- Next generation program design
- Public Buildings
- Advanced specification
- Tax Credit (In Congress)
*How to* exceed ASHRAE by 50%
- Energy Codes
- Next generation code levels

## Benefits

- Lower cost per transaction
- High quality materials and pre-defined path provide economical access to guide smaller buildings
- Cost effective whole-building performance solution
- Comprehensive educational materials
- Connections to LEED, rebates, etc.
- Assist in implementing market transformation strategy
- Guidelines “pull” market beyond standard practice
- Codes “push” market to standard practice
