Energy Analytical Models: A Holistic Energy Assessment Technique

1. Energy Analytical Models:A Holistic Energy Assessment Technique Doug Dixon Pacific Northwest National Laboratory 20 June 2007

2. Agenda • Army SE Region Energy Performance • Energy Modeling/Assessment Results at SE Region Installations • What is the Facility Energy Decision System (FEDS)? • Other applications of FEDS

3. SE Region Glide Path Performance(through FY 2006)

4. SERO Installation Energy Assessments SERO conducted comprehensive installation energy assessments using the Facility Energy Decision System (FEDS) software. Specific goals of these assessment were: • Establish baseline for installation energy consumption and costs. • Identify and prioritize cost-effective energy projects for funding via third party financing (ESPC, UESC, BPA), and/or government funding (ECIP, OMA). • Estimate impact on energy demand and consumption from new building construction, demolition, renovation, utility modernization, O&M, and energy-specific retrofits. • Provide input for Installation Long-Range Energy Management Plan.

5. FEDS General Approach • Collect information on building inventory, energy-related infrastructure, energy consumption and prices • Sort building inventory into groups with common characteristics and audit representative buildings (typically 25-30 buildings) • Characterize central energy plant and thermal distribution system performance • Utilize Facility Energy Decision System (FEDS) building energy model to calculate energy consumption of building groups • Calibrate the model to actual energy use using actual weather data • Utilize the model to predict energy use impact of infrastructure changes, and identify life-cycle cost effective retrofits using typical weather data (TMY).

9. An Overview of Facility Energy Decision System

10. FEDS - What is it? • FEDS is a fuel-neutral, technology independent, comprehensive method for quickly and objectively identifying building energy efficiency improvements that offer maximum savings

11. Why was FEDS Developed? • Large military bases needed a tool to help them determine where their energy was going and what energy opportunities existed • Bases had: • hundreds and often thousands of buildings, and usually only one meter • little detailed engineering information on individual buildings • limited understanding of utility information • Key elements missing in existing software programs

12. FEDS Design Goals • FEDS was designed with two major purposes in mind: • estimating current energy consumption for all energy systems under consideration • determining the minimum life-cycle-cost retrofits to systems within a facility and on an installation (considering all interactive effects) and includes estimating: • pre- and post-retrofit consumption • first cost of the retrofits • recurring O&M costs for the retrofits • value of the change in annual energy consumption and annual O&M requirements • net present value of the retrofits

13. FEDS is Unique Peak tracking Life-cycle cost optimization Technology & fuel independence Financial options

17. FEDS Required Inputs • Installation and Financial Information • Location and Analysis Year • Energy Price Data • Cost of Money (if not DOE/EIA) • Building Information • Type, Age, Size, and Quantity • Operating Hours • Equipment (Lights, Heat, Cool, Hot Water)

19. FEDS Results • Energy consumption: total, by fuel type, by end use, by building set, by central plant • Suggested retrofits: specific technologies to install and replace, capital cost, energy and cost savings, net present value • Peak demand: amount and time, for installation and by building set • Emissions: by pollutant type, by building set

20. Report Options • A summary report of the energy, demand, dollar, and air pollution emissions impacts for the installation, central plants, and building sets (*.txs) • A detailed retrofit report (*.txd) • A detailed spreadsheet of retrofit data (*.csv) • An Energy Conservation Investment Program report (*.ecp) – for single retrofits only (no bundling)

21. Other FEDS Uses • Evaluate alternative sustainable building designs • Analyze fuel switching • Value “deals” • Assess impacts of change • Apportion reimbursable customers • Central plant and thermal loop analysis (optimize amount of decentralization)

22. Building Design Evaluation Use FEDS to assess the impact of building designs during the design review stage. FEDS can indicate the impact the new building(s) will have on your facility (energy and dollars), and it can indicate energy efficient retrofit technologies before the design goes to construction.
