1 July 20, 2012 The International Green Construction Code: Vision to Action International Green Construction Code

2 The Code of Hammurabi King Hammurabi of Babylon ca B.C. If a builder builds a house for someone, and does not construct it properly, and the house which he built falls in and kills its owner, then the builder shall be put to death. History of Codes

3 History of Codes

4 Buildings fundamentally have an impact on people's lives, economic well being. In the United States, residential and commercial buildings together use more energy and emit more carbon dioxide than either the industrial or transportation section. Energy-efficient buildings offer both tangible and intangible energy, economic, and environmental benefits. Energy efficient buildings can also create economic opportunities for business and industry by promoting new energy efficient technologies. Why is a Green Code Needed?

5 Why is a Green Code Needed?

6 IgCC is intended to reduce the negative impacts of the built environment on the natural environment. Resource Conservation Land Use Reducing Waste Reducing Pollutants Focus on Performance and Accountability

7 IgCC Subject Areas 1. Energy use efficiency 2. The buildings impact on environment (Greenhouse Gas) 3. Water use efficiency 4. Materials and resource use 5. Indoor environment quality 6. Site design 7. Sustainable building owner/facility management education 8. Existing buildings ENERGY SAVINGS 30% CARBON SAVINGS 35% WATER USE SAVINGS 30-50% WASTE COST SAVINGS 50-90%

8 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

9 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 promote green building into everyday practice

10 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.

11 IgCC Concepts 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?

12 CODE VS STANDARD VS RATING SYSTEM LEED IGCC ASHRAE Why codify best practices?

13 The push-pull between codes & standards

14 The push-pull between codes & standards

15 One of the values of the IgCC is that it is designed to coordinate and integrate with the existing I-Codes. The IgCC offers various tiers of jurisdiction to apply to commercial and high performance buildings. In a manner that incorporates the heath and safety features of the other I-Codes. What is an Overlay Code?

16 Adoptable Usable Enforceable Works as an overlay to the ICC code family Minimum & advanced levels of green Performance, prescriptive and outcome-based paths Accounts for local conditions (flood areas, greenfield sites, light pollution, etc.) Designed with local, state & federal law in mind IgCC Development Concepts

17 Adoptable Usable Enforceable IgCC Intent. The purpose of this code is to safeguard the environment, public health, safety and general welfare through the establishment of requirements to reduce the negative potential impacts and increase the positive potential impacts of the built environment on the natural environment and building occupants, by means of minimum requirements related to: conservation of natural resources, materials and energy; the employment of renewable energy technologies, indoor and outdoor air quality; and building operations and maintenance. IgCC Development Concepts

18 Chapter 1: Administration Chapter 2: Definitions Chapter 3: Jurisdictional Requirements & Project Electives Chapter 4: Site Development & Land Use Chapter 5: Material Resource Conservation & Efficiency Chapter 6: Energy Conservation, Efficiency & Atmospheric Quality Chapter 7: Water Resource Conservation & Efficiency Chapter 8: Indoor Environmental Quality & Comfort Chapter 9: Commissioning, Operation & Maintenance Chapter 10: Existing Buildings Chapter 11: Existing Building Site Development Appendix A: Optional Ordinance Appendix B: Greenhouse Gas Reductions In Existing Buildings Appendix C: Sustainability Measures Content

19 CHAPTER 3 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 (Replaces Chapters 4 through 12) 3. Project Electives. 4. Whole Building Life Cycle Assessment FLEXIBILITY allows adopting jurisdiction to define priorities Jurisdictional Requirements Project Electives A Few Highlights Project Electives

20 Local Jurisdictions Control Chapter 4 Site Development and Land Use Preservation of Natural Resources Protection by area: e.g. floodplains, conservation areas, park lands, agricultural lands, greenfields. Site design and development requirements: Pre-design site inventory and assessment Stormwater management, Landscape irrigation systems, Management of vegetation and soils Site waste management plan.

21 Chapter 4 Continued, Transportation impact. Walkways and bicycle paths Changing and shower facilities Bicycle parking and storage Vehicle parking Heat island mitigation. Site hardscape,roof coverings Light pollution mitigation. Detailed site development requirements. Subsurface graywater irrigation systems Vegetation and soil protection Landscape, soil and water quality protection plan

22 CHAPTER 5 MATERIAL RESOURCE CONSERVATION & EFFICIENCY Material Selection Criteria Materials and their properties. 55% of materials used in every project must be any combination of the following Used, Recycled, recycleabe, Bio-based or Indigenous. Service Life Whole Building Life Cycle Assessment A Few Highlights Materials

23 CHAPTER 6 ENERGY CONSERVATION AND EFFICIENCY Buildings > 25,000 sq. ft. must use the performance based compliance path Uses Zero Energy Performance Index (zepi) concept encourages use of renewable energy, cogeneration and zero net energy buildings. Buildings < 25,000 sq. ft. may use any of the following : Performance based path Prescriptive based path Energy Use Intensity (EUI) path Must be in top 10% of EPA s Target Finder Program Outcome based path Estimated energy use relative to actual energy use, based on a 12 month period after C of O. A Few Highlights Energy

24 CHAPTER 7 Water Resource, Conservation & Efficiency Plumbing systems and conservation measures. Landscaping and irrigation addressed in Chapter 4. Specific water savings measures. Use of grey water, rain collection and storage.

25 CHAPTER 9 COMMISSIONING and O & M Commissioning Plan Ends at Certificate of Occupancy Owner or tenant post occupancy operations. Building maintenance. Education of building users. A Few Highlights Commissioning

26 CHAPTER 10 Existing Buildings Loosely based on the provisions of the IBC/IEBC 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. 26
