Matching Energy Models & METER Magic Overview

• Importance of Matching to Existing Utilities
• Getting started
• 7 Step Process
• Spreadsheet success

Why Match Energy-Models

• Crucial cross-roads in the Building Simulation
• Scalar savings?
• They won’t believe you!
• “Lingua Franca”
• $$$

After this course

• Understand the 7 step process to get BEM to match reality
• Use the model matching spreadsheet
• Simplify categories of energy consumption and peak demand
• Use associated tools
• Determine where to put your focus

Due Diligence

• Before we can start
• Verify Confirmable inputs (Cooling COP, LPD, etc)
• Determine Climate Zone
• Determine Building Fuel Types
• Special Circumstances (Absorption chiller)

7 Step Process

• Verify Your Peak Loads
• Complete Energy Model and Obtain 12 months of Utility bills (or as much as possible)
• Determine Energy Usage for model and Utilities
• Plot Patterns, focus on July, January, and Annual Totals
• Run METER
• Implement the Suggestions
• Consider swing months and user experience

Infinite Inputs

• Cooling Efficiency
• NET SEER
• COP/EER
• Economizers
• Fluid Coolers
• Evaporative coolers
• Heating Efficiency
• NET Heating Efficiency
• Heating Efficiency
• ERV Units
• Hot Gas Bypass
• Make note of special circumstances!
