Applying the 90.1-2016 Energy Code

• Introduction to 90.1-2016

• Performance Cost Index

• Case Study: Utility Administration Building

Agenda

• Recognize new terminology

• Performance Rating Method

• Understand sensitivity

• Apply in other code cycles and LEED

Learning Objectives

• New Climate Zone 0A and 0B

• Reassigned climate zones

• Infiltration verification

• 5B: Opaque doors, fenestration

• Lighting power and controls

• Chilled water plant metering

• DOAS requirements

• Elevator efficiency

• Economizer/DX fault detection and diagnostics
