1. Southeastern Regional Building Commissioner’s Association Overview of the International Green Construction Code (IgCC) Doug Connell International Code Council September 2011

2. What is the IgCC? An Adoptable, Useable and Enforceable code Intended to reduce the negative impacts of the built environment on the natural environment Addresses Conservation of: Natural resources Materials Energy Water Air & indoor environmental quality Owner education

3. Scope and Intent Consistent and coordinated with the ICC family of Codes & Standards Applicable to the construction of New and existing buildings All buildings other than residential buildings under the scope of the IRC Intended to be enforced primarily by building officials – a system already in place nation wide Intended to drive green building into everyday practice

4. IgCC Concepts The IgCC is not a rating system, nor is it intended to replace them. The IgCC is code which is intended to be adopted on mandatory basis. Unlike most rating systems, the IgCC primarily consists of minimum mandatory requirements, just as other I-Codes.

5. How should we compare green and sustainable codes, standards, rating systems and programs? Building by building? - Or - By their ability to be adopted on a mandatory basis in all regions and potential overall reduction of negative environmental impacts? What should the intent of a green code or program be? To make a few buildings very green? - Or - To have as large a positive impact and as little a negative impact as possible on the total natural environment? Not just local, not just the U.S., but the entire planet. IgCC Concepts

6. Because the IGCC is intended to apply to both private sector and government owned buildings on a mandatory basis – it Raises the floor of sustainability for all commercial buildings. Positions the IGCC to achieve environmental benefits on a massive scale – a scale not possible with voluntary rating systems.

7. Provides many detailed prescriptive requirements, as well as performance targets, which are quantified and enforceable. Does not award innovation without merit or the implementation of theories without real world value. Contains many detailed requirements, including: Gray water system details Irrigation system details Rainwater catchment system details Actual energy provisions IgCC: Detailed and Comprehensive 7

8. Chapter Topics 1: Administration 2: Definitions 3: Requirements determined by the jurisdiction and project electives 4: Site development & land use 5: Materials resource efficiency 6: Energy conservation and efficiency 7: Water conservation and efficiency

9. Chapter Topics 8: Indoor environmental quality 9: Commissioning, operation and maintenance 10: Existing buildings 11: Existing building sites 12: Referenced standards Appendices  A: Optional Ordinance  B: Greenhouse Gas Reductions in Existing Buildings  C: Sustainability Measures  D: Enforcement Procedures

10. SCOPE New and existing construction All buildings other than those covered by the IRC The IgCC is an overlay code. Compliance enforced as part of other applicable codes. References other I-Codes IBC, IFGC, IMC, IPC, IPMC, IFC, IWUIC, ICCPC, IEBC, IZC.. Chapter 1 Administration 10

11. Does not circumvent the requirements of other codes, but often exceeds them. Regulates sustainable aspects of construction not covered by other codes. Regulates the impact of the built environment on the natural environment. Chapter 1 Administration 11

12. Shares some definitions which are common to other International codes. Primarily provides definitions unique to the IgCC. Examples: Approved Approved Agency Building Commissioning Construction Documents Control Daylight Control Occupant Sensor Control Chapter 2 Definitions 12

13. Demand Response, Automated Energy Management and Control System Registered Designer in Responsible Charge Sequence of Operation Chapter 2 Definitions 13

14. LIFE CYCLE ASSESSMENT (LCA). A technique to evaluate the relevant energy and material consumed and environmental emissions associated with the entire life of a building, product, process, material, component, assembly, activity or service.

15. Chapter 3 is unique in that the focus will be on stringency of the entire document as adopted by the jurisdiction. Focus is on adoptability through flexibility of the document to coordinate with the local jurisdictions environmental goals and specific regional geography. Four (4) major components of Ch 3: 1. Jurisdictional Requirements. 2. Option to adopt ASHRAE Standard 189.1 (Replaces IGCC Chapters 4 through 12) 3. Project Electives. 4. Whole Building Life Cycle Assessment Project Elective. Chapter 3 15

16. Chapter 3 – Jurisdictional Requirements Allows jurisdictions to make choices which: 1. Can tailor the code to address environmental concerns of a local nature. 2. Respond to environmentally related local political agendas. 3. Apply to all buildings constructed in the jurisdiction. 4. Determine whether certain provisions will be enforced. Internal document confidential information for ICC

17. IgCC Table 302.1 allows regional choices, similar in concept to Table R302.1(1) in the IRC. Allows jurisdictions to make choices for higher levels of stringency by: Determining whether certain provisions will be enforced in the jurisdiction. (Typically yes or no answers.) Decisions made in Table 302.1 apply to all buildings constructed in the jurisdiction. Many of the choices in Table 302.1 may pose risks for certain jurisdictions. (Thus they may pose a barrier to adoption in some regions and are not mandatory for all jurisdictions.) Table 302.1 Jurisdictional Requirements 22 Choices affecting Chapters 4 through 10 17

19. Allows owners and design professionals to make choices which:  Encourage and drive the construction of buildings which exceed the already stringent minimum requirements of the code.  Encourage practices which are difficult to mandate.  Adds a degree of flexibility to the code.  Jurisdiction determines minimum number that must be satisfied in Table 302.1.  Owner chooses which electives will be complied with on a project by project basis.

54. Loosely based on the provisions of the IBC for existing buildings:  For alterations/renovations: whatever is changed must meet current IgCC requirements.  Unaltered components can remain as they are.  Additions are treated much like new construction: applicable requirements of the IgCC must be satisfied. Section 1002.1: Prohibits the construction of additions to buildings in flood hazard areas.  Exception: where all habitable space is located at least 1 foot above flood elevation. Chapter 10 Existing Buildings 54

55. Alterations to Existing Buildings:  Basic prescriptive requirements addressing:  Leaks  Defective equipment and systems  Extensive prescriptive list limited to 10% of the cost of alterations.  Triggered by any change of occupancy or alteration. Chapter 10 Existing Buildings 55

57. Frequently Asked Questions

58. What about residential properties? The ICC co-developed the National Green Building Standard (NGBS), otherwise known as ICC 700-2008, with the National Association of Home Builders (NAHB). It is not referenced in the IgCC. Residential buildings that are not covered in the IRC must the IGCC.

59. Who is supporting the ICC in this effort? The AIA and ASTM-International are the “Cooperating Sponsors” for this initiative, and as such have an active role in the development process. Other organizations who participated in the development include the U.S. Green Building Council (the purveyor of the LEED rating system), the Green Buildings Initiative (GBI), ASHRAE as well as state and local officials. Well over 100 organizations and individuals participated in the development effort. Standard 189.1, included as a jurisdictional compliance option, was developed by ASHRAE, USGBC and the Illuminating Engineering Society (IES). Those organizations have now joined in the effort to promote the IGCC.

60. How does the development process work? The ICC Board created a Sustainable Building Technology Committee (SBTC) composed of 28 individuals from multiple sectors, to draft Public Version 1.0. The SBTC conducted open meetings around the U.S. between July 2009 and January 2010, creating IGCC Public Version 1.0 as a tool for jurisdictions wishing to develop a code based on the ICC process. A Public Version 2.0 was released in November 2010 after public comments and hearings. It is published for comments now. In 2011, Code Development and Final Action Hearings will deliver the 2012 IGCC.

61. How does the development process work? This process tracks the development of the other codes in the I-Codes series. Once the 2012 Code is issued, it will be revisited every three years along with the other I-Codes, through the two-hearing process used to update all of the I-Codes.

62. What is the difference between the IGCC and other systems and standards such as LEED, Green Globes, etc. ? The IGCC creates a regulatory framework for new and existing commercial and high-performance buildings. Rating systems are not written in the form of enforceable codes, acting as optional approaches, such as awarding points based on the inclusion of certain design elements and other features with the assumption is that the combination and concentration of favored elements will result in a positive environmental impact. The IGCC will build on that foundation to ensure that measurable building performance and an adherence to building safety will be featured in the model code language. It is anticipated that the IGCC will look to existing rating systems and standards as resources in developing the regulatory framework.

63. How will the IGCC differ from other International Codes such as the International Building Code (IBC)? One of the values of the IGCC is that it will be designed to coordinate and integrate with existing I- Codes. The IGCC includes various levels for jurisdictions to apply unique “green” requirements to commercial buildings. The IGCC will not replace the IBC but rather can be adopted and used in conjunction with the adopted IBC, as well as all the other I-Codes.

64. Why is the ICC promoting its Green Construction Code when other options already exist ? The development of a code occurs when there is a clear need indicated from regulators and others in the building safety industry. In the case of the IGCC, there has been an increasing call for an actual code that is clear and enforceable. We have heard this not only from our members in local and state government, but from stakeholders across the spectrum. This is why the AIA and the ASTM have joined the ICC as “Cooperating Sponsors.” For example, architects want a code book that will guide their design activities just like the other I- Codes. The inclusion of ANSI/ASHRAE/USGBC/IES Standard 189.1 provides the jurisdiction the option of using either the IGCC or Standard 189.1.
