## Energy Efficient Technologies

**Energy Efficient Technologies**

- Roger Duncan, Deputy General Manager

- Cost Effective Integration into Buildings: A Utility's View

## Background

- Started DSM/Peak Management Programs in 1982
- Residential Incentive Programs
- Commercial Incentive Programs
- First Green Building Program in U.S. 1991
- Residential 1992
- Municipal Guidelines 1994
- Commercial 1995
- District Cooling and Distributed Generation 2001
- Conservation Power Plant to Date: 590 Mw

## Green Building

- Captures Lost Opportunity Savings Through Energy Efficient Design
- Building orientation
- Shell improvements
- Natural daylighting
- Manages Energy Code
- Amends national codes to meet local needs
- Monitors and educates city inspectors

## Green Building

- Enhances Value to Building Owners, Community and Environment by Adding:
- Water conservation/quality
- Efficient materials use
- Indoor environmental quality
- Community issues-site selection, infrastructure impact
- Most Cost Effective EE Program < $100/kW

## DSM/Peak Management Programs

- Provide Incentives for Energy Efficient Equipment Selection
- HVAC equipment
- Lighting
- Insulation
- Reflective roofing materials
- Moderate Cost $200-$350 Per kW

## Must Meet AE Effectiveness Criteria
Cost effective for utility
Cost to build/finance generation/deferred revenue
Cost effective for end users 
Payback period of incremental costs
Positive societal impacts
Reduced utility costs
Emissions reductions

- Cost effective for utility
- Cost to build/finance generation/deferred revenue
- Cost effective for end users
- Payback period of incremental costs
- Positive societal impacts
- Reduced utility costs
- Emissions reductions

- _DSM/Peak Management Programs_

## District Cooling

- Downtown and Airport District Cooling Systems with Thermal Storage Systems
- Campus or Development Based Central Chilled Water Systems
- District cooling moves AE to energy service model v. pure kWh sales
- Thermal storage shifts large loads from peak

## Distributed Generation

- Combined Cycle Turbines
- Combined heat and power
- Experimental Fuel Cells
- Power, heat and hot water at assisted living facility
- 5 kW residential fuel cell

## Making It All Work

- Seton Children’s Hospital
- 450,000 sq. ft. hospital in 34 acre medical facility park
- USGBC LEEDTM Platinum Building
- Targeting 60% more energy efficient than code (ASHRAE 90.1)

## Seton Children’s Hospital

- Green Building Program
- Design assistance (energy)
- Passive solar orientation
- Energy efficient shell
- Natural daylighting and lighting controls
- Green roof

## Seton Children’s Hospital

- Design Assistance with Other Green Building Issues
- Water conservation/quality
- Storm water management
- Indoor environmental quality
- Materials selection

## Seton Children’s Hospital

- DSM/Peak Load Management
- Incentives for high efficiency equipment
- Lighting and controls
- Reflective roofing

## Distributed Generation and District Cooling

- Combined Cycle Turbine
- Provides all electricity for building
- Waste heat meets needs for heat and hot water
- Provides power for AE owned chiller
- AE Owned On-Site Chiller Plant
- Provides cooling for hospital and future buildings

## Utility Benefits

- Providing Higher Value Product
- Energy services v. kWh
- Reduced Load on Distribution System
- Reduced Load on Central Power Plants
- Reduced First Cost Due to Energy Efficiency
- Large Customer Under Long Term Contract

## End User Benefits

- Higher Value Building
- Energy efficient
- Healthier (more productive workforce)
- Reduced equipment first cost
- Reduced O&M costs
- Higher level of reliability

## Technology Issues – Key Questions

- What are the primary RE & EE technologies being applied to state and regional electricity markets, and what do you think they will be in the future?
- What are the opportunities for EE & RE technologies in state and regional electricity markets?
- What are the analytic issues affecting development of RE & EE technologies in these markets?
- What analysis tools are available, and how could they be enhanced or improved to address needs?
- What additional information (analysis tools or studies) would be valuable in expanding the use of renewable energy in electricity markets?
