ASHRAE Standard 189.1-2014, Standard for the Design of 

High-Performance Green Buildings

3

• Standard 189.1 provides total building 

sustainability guidance for designing, 

building and operating highperformance green buildings

• Has broader scope than Standard 90.1

• Partners with the International Code 

Council (ICC) for the International Green 

Construction Code (IgCC)

• Single resource on green buildings “IgCC

powered by 189.1” to be published in 

summer 2018

• Beneficial for those in design, 

construction, installation, 

commissioning, operation, 

maintenance and service of centralized 

building water systems and 

components

• Standard 188 establishes minimum 

legionellosis risk management 

requirements for building water 

systems

• This is the foundation of the CDC’s 

Toolkit entitled “Developing a Water 

Management Program to Reduce 

Legionella Growth and Spread in 

Buildings”

• Standard 90.4 was designed to 

ensure only the most inefficient data 

centers are non-compliant

• Is aggressive but has very achievable 

mechanical and electric efficiency 

requirements that save agencies 

money

• Data centers are often the largest 

energy users at an agency

• Works in concert with Standard 90.1

ASHRAE Standard 90.1-2016, Energy Standard for Buildings Except 

Low-Rise Residential Buildings

• Standard 90.1 is a benchmark for 

commercial building energy codes

• ASHRAE has set forth efforts to 

address plug load reduction and 

help design teams account for 

them when evaluating building 

loads with Standard 90.1

• “Regulated loads” are no longer 

included in a summary of energy 

savings in the Standard 90.1 

revision in 2016

• Plug loads will continue to be a 

critical component in achieving 

Advanced Energy Design Guides

• With the help of our industry leaders and volunteers who 

devote many hours of their time, we are continuously 

reaching our goal of providing resources to all stakeholders in 

the buildings industry

• ASHRAE has compiled an extensive webpage of resources on 

Advanced Energy Design Guides, which can be found at
