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:

Mandatory vs. Elective Provisions

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

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.

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.

(simple option, very few calculations)

(more options, but more effort)

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)
