LEED is an voluntary Rating
System with Design Guidance
The intent of ASHRAE 189.1 is to: ◦ Codify the minimum
requirements of a high performance green building
◦ Develop an international Green Construction Code
◦ Mandate minimum requirements for high performance green buildings
Consistent and coordinated with the ICC family of Codes & Standards
Intended to be enforced primarily by building officials
Intended to drive green building into everyday practice
Applicable to the construction of All buildings, both old and new, except small residential buildings.
IgCC developed by ICC in association with cooperating sponsors:
ASTM and
AIA
References ASHRAE 189.1 as an alternative compliance path, as developed by:
ASHRAE and partners
IES and
USGBC
Developed By:
Provides minimum criteria that:
◦ Apply to new commercial and industrial buildings
and major renovation projects
◦ Addresses site sustainability, water and energy
efficiency, indoor environmental quality (IEQ) the
building’s impact on the atmosphere, materials
and resources.
Does not apply to:
◦ Small residential; buildings that do not use
electricity, fossil fuel or water

Mandatory criteria in all topic areas
Simple prescriptive compliance options
Flexible performance compliance options
Complement green building rating programs
ASME - American Society of Mechanical Engineers
USDOE – United States Department of Energy
USGBC – United States Green Building Council
USEPA – United States Environmental Protection Agency
CA DHS EHLB R-174 -Indoor Air Quality Section - Involves testing of chemicals related to air quality (paints, coatings, sealants, adhesives, wall coverings, floor coverings, wood paneling and furniture components.
Green Seal - has sustainability standards for products, services, and companies; 31 issued standards that cover over 375 product and service categories.
ASTM - (American Society for Testing and Materials) - International standards organization for a wide range of materials, products, systems, and services. Claims to be the world's largest developer of standards; more than 12,000 standards.
BIFMA – Business Institutional Furniture Manufacturers association develops, maintains, and publishes safety and performance standards for furniture products.
IESNA - The Illuminating Engineering Society of North America (IES); technical authority on illumination. Over 100 publications on lighting, many of which are ANSI standards

ASHRAE Standard 62.1 - Ventilation for Acceptable Indoor Air Quality. Quantifies
acceptable conditions and appropriate HVAC system design. Standard 62.1 forms the basis for mechanical codes or is directly referenced by the codes. (does not cover low-rise residential buildings and single-family dwellings)
ASHRAE 90.1 - US standard that provides minimum requirements for energy efficient designs for buildings except for low-rise residential buildings.
ASHRAE Standard 55-2010 - defines the range of indoor thermal environmental conditions acceptable to a majority of occupants.
ASHRAE/ACCA Standard 180 – 2012 - A standard practice for inspection and maintenance of commercial HVAC systems to improve thermal comfort, energy efficiency, and indoor air quality.
ASHRAE Guideline 0 - Addresses best practices for applying whole-building commissioning to facilities; includes the Total Building Commissioning Process (TBCxP) as defined by National Institute of Building Sciences (NIBS) in its Commissioning Process Guideline 0.

Reduce Heat Island Effect:
•Shaded or higher solar reflective index (SRI) materials
Reduction of Light Pollution:
•Max lumens per site •Backlight and glare limits
Site Water Use Reduction bio-diverse plantings
hydro-zoning
smart irrigation controllers
Building Water Use Reduction Plumbing fixtures & fittings per US EPA
WaterSense or ASME Standards (generally 40% lower than EPAct 1992)
Appliances per US EPA EnergyStar, with water use factor for public access appliances
HVAC Systems and Equipment – Once through cooling w/ potable water prohibited
Water Metering Lease space >50,000 ft2
Other users >1000 gal/day

Mandatory requirements
Renewable energy
provisions
Meters ◦ Remote or automatic
reading ◦ Central recording system ◦ Data storage for
minimum 36 months
Required to provide for future installation of
on-site renewable energy systems.
Based on a minimum rating of 3.7 W/ft2 multiplied by the total roof area in ft2.
Roofs must be designed to account for structural support requirements and local wind conditions.
Exceptions for low incident solar radiation
Purchase Green power of 70 kWH/ft2 for a period of 10 years.

A prescriptive code requires that each component be built to a certain standard, e.g. Wall R-value at
least 20. (simple option, very few calculations)
A performance code requires that the building as a whole perform to a certain standard, e.g. uses less energy than the same building, built to
prescriptive code (more options, but more effort)
