2 LEED is an voluntary Rating System with Design Guidance The intent of ASHRAE 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

3 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.

4 Developed By: IgCC developed by ICC in association with cooperating sponsors: ASTM and AIA References ASHRAE as an alternative compliance path, as developed by: ASHRAE and partners IES and USGBC

5 Mandatory vs. Elective Provisions

6 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 Smart Buildings, LLC 6

7 Mandatory criteria in all topic areas Simple prescriptive compliance options Flexible performance compliance options Complement green building rating programs

8 Project committee Voting members Variety of disciplines, industries & organizations

10 ASME - American Society of Mechanical Engineers USDOE United States Department of Energy USGBC United States Green Building Council 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. 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. 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 Smart Buildings, LLC 10

11 ASHRAE Standard 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 US standard that provides minimum requirements for energy efficient designs for buildings except for low-rise residential buildings. ASHRAE Standard defines the range of indoor thermal environmental conditions acceptable to a majority of occupants. ASHRAE/ACCA Standard 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.

21 Mandatory requirements Renewable energy provisions Meters Remote or automatic reading Central recording system Data storage for minimum 36 months

22 Required to provide for future installation of on-site renewable energy systems. Based on a minimum rating of 3.7 W/ft 2 multiplied by the total roof area in ft 2. 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/ft 2 for a period of 10 years. Smart Buildings, LLC 22

23 + (simple option, very few calculations) + (more options, but more effort)

24 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) Smart Buildings, LLC 24
