1. Northwest Power and Conservation Council New Commercial Building Program Quest Presentation, Discussion and Decision of Proposed Approach to Estimating Savings for New Commercial Buildings November 13, 2006

2. Northwest Power and Conservation Council slide 2 Goal A prescriptive program for selected small new commercial construction (CNC) A prescriptive program for selected small new commercial construction (CNC) –Office, school, public assembly & perhaps retail Whole-building, integrated measure approach where possible & effective Whole-building, integrated measure approach where possible & effective Deemed or deemed calculated savings Deemed or deemed calculated savings Commonality across the region Commonality across the region Training for designers & builders & developers Training for designers & builders & developers Marketing and outreach Marketing and outreach Evaluation Evaluation

3. Northwest Power and Conservation Council slide 3 Progress CNC Strategy Group hosted by BPA CNC Strategy Group hosted by BPA –BPA, PacifiCorp, NEEA, Springfield, Seattle, Tacoma, SnoPUD, Puget, EWEB, Council, Energy Trust, Idaho Power Reviewed savings potential & market Reviewed savings potential & market Reviewed existing programs Reviewed existing programs –Some mature, some emerging, diverse Identified common needs & issues Identified common needs & issues Reviewed approaches to prescriptive Reviewed approaches to prescriptive Reviewed cost estimates for measures Reviewed cost estimates for measures

4. Northwest Power and Conservation Council slide 4 Approach to Savings Based on work of New Buildings Institute for Advanced Buildings Guidelines 2.0 Based on work of New Buildings Institute for Advanced Buildings Guidelines 2.0 –Measures evaluated against ASHRAE 90.1 2004 –Improved bundling of integrated measures for better performance –Sophisticated modeling approach –May be used by USGBC for LEED points For PNW baseline, use “Best of Region” MCS For PNW baseline, use “Best of Region” MCS –Conservative, better than any single state code For representative PNW climates For representative PNW climates

5. Northwest Power and Conservation Council slide 5 Measures to be Analyzed in NBI ABG 2.0 1. R30 roof insulation, 2. R19 wall insulation, 3. Windows, up to a 30% window-wall ratio, U=0.35, SHGC=0.4, 4. Skylights, 5% of roof area, U=0.40, 5. Exterior shading of windows,

6. Northwest Power and Conservation Council slide 6 Measures to be Analyzed in NBI ABG 2.0 6. Occupancy and continuous dimming lighting controls and ballast upgrades 7. Daylight controls 8. HVAC roof top unit (RTU) upgrade to 13 SEER 9. HVAC RTU upgrade to 14 SEER 10. Re-sizing HVAC for reduced, actual load, including improved part load efficiency

7. Northwest Power and Conservation Council slide 7 Measures to be Analyzed in NBI ABG 2.0 11. Evaporative pre-cooler, premium efficiency motors, heat recovery, demand controlled ventilation (DCV) & variable frequency drives (VFD) 12. Advanced economizer control, including 2-stage cooling thermostat & “western premium economizer” features 13. Building wide direct digital control (DDC) 14. Lighting power density less than 0.9 watts/sft.

8. Northwest Power and Conservation Council slide 8 Modeling Approach eQUEST (DOE2) batch run protocols developed for ABG 2.0 (Kevin Madison) Measures prioritized for savings Estimates for bundled/integrated measures Plus estimates for individual measures Run for multiple HVAC systems & fuel types Run for 5 climates via TMY data for Boise, Missoula, Portland, Seattle & Spokane Initial incremental measures cost estimates done

9. Northwest Power and Conservation Council slide 9 Schedule BPA to contract with NBI for modeling & PNW results by February 2007 BPA to contract with NBI for modeling & PNW results by February 2007 Review results Review results –CNC strategy group & RTF contractor or sub- committee –Determine need for & scope of PNW baseline runs Determine next steps to develop program Determine next steps to develop program BPA wants program offer by April 2007 BPA wants program offer by April 2007
