1 ASHRAE/USGBC/IES Standard Kent W. Peterson, PE, FASHRAE, LEED ® AP Standard for the Design of High-Performance Green Buildings Optional Compliance Path to the IgCC Standard for the Design of High-Performance Green Buildings Optional Compliance Path to the IgCC

2 STANDARD FOR THE DESIGN OF HIGH-PERFORMANCE GREEN BUILDINGS 2 What is Standard 189.1?  ANSI standard being developed in model code language  Provides minimum requirements for high-performance, green buildings  Applies to all buildings except low-rise residential buildings (same as ASHRAE/IESNA Std 90.1)  Optional Compliance Path to the International Green Construction Code (IgCC)  Not a design guide, not a rating system

3 STANDARD FOR THE DESIGN OF HIGH-PERFORMANCE GREEN BUILDINGS 3 Standard Project Committee  Sponsor and co-sponsors  ASHRAE - American Society of Heating, Refrigerating and Air Conditioning Engineers  USGBC – U.S. Green Building Council  IES - Illuminating Engineering Society of North America  Project committee  37 total members  Diverse backgrounds  Consensus process with four public reviews

4 STANDARD FOR THE DESIGN OF HIGH-PERFORMANCE GREEN BUILDINGS 4 Goals for Standard  Establish mandatory criteria in all topic areas  One “challenge” is existing green building rating systems contain few mandatory provisions  Provide simple prescriptive compliance options  Provide flexible performance compliance options  Complement green building rating programs  Standard is not intended to compete with green building rating programs

5 STANDARD FOR THE DESIGN OF HIGH-PERFORMANCE GREEN BUILDINGS 5 Development of Standard Preliminary meeting (Jun) st public review (May-Jul) nd public review (Feb) Committee reconstituted (Nov) rd public review (May-Jun) 4th public review of ISCs (Sep-Oct) Publication approval (Dec) 2010 Publication (Jan 22nd) Transition to SSPC

6 STANDARD FOR THE DESIGN OF HIGH-PERFORMANCE GREEN BUILDINGS 6 Status of Standard  Approved for publication by:  Project committee (SPC 189.1)  ASHRAE Leadership, including Board of Directors  USGBC  IES  Right to appeal - unresolved commenters

7 STANDARD FOR THE DESIGN OF HIGH-PERFORMANCE GREEN BUILDINGS 7 What Happens When Green Becomes Code? Do Buildings Get Better?

8 STANDARD FOR THE DESIGN OF HIGH-PERFORMANCE GREEN BUILDINGS 8 Standard Building Blocks

9 STANDARD FOR THE DESIGN OF HIGH-PERFORMANCE GREEN BUILDINGS 9 Compliance Paths Mandatory + Prescriptive Path Performance Path Mandatory + (simple option, very few calculations) (more options, but more effort)

10 STANDARD FOR THE DESIGN OF HIGH-PERFORMANCE GREEN BUILDINGS 10 Standard Topic Areas SSSS WEWE EEEE IEQIEQ MRMR COCO Sustainable Sites Water Use Efficiency Energy Efficiency Indoor Environmental Quality Building’s Impact on the Atmosphere, Materials & Resources Construction and Operations Plans

11 STANDARD FOR THE DESIGN OF HIGH-PERFORMANCE GREEN BUILDINGS 11 Sustainable Sites Highlights 1. Site Selection 2. Reduce heat island effect 3. Reduce light pollution SSSSWEWEEEEEIEQIEQMRMRCOCO

12 STANDARD FOR THE DESIGN OF HIGH-PERFORMANCE GREEN BUILDINGS 12 Water Use Efficiency Highlights  Site Water Use  Bio-diverse plantings, hydrozoning, & smart irrigation controllers  Building Water Use  Plumbing fixtures & fittings, appliances, HVAC systems & equipment, generally 40% lower than U.S. EPAct 1992  Cooling tower maximum cycles of concentration  Water Measurement for building and subsystems SSSSWEWEEEEEIEQIEQMRMRCOCO

13 STANDARD FOR THE DESIGN OF HIGH-PERFORMANCE GREEN BUILDINGS 13 Building Energy Codes ENERGY

14 STANDARD FOR THE DESIGN OF HIGH-PERFORMANCE GREEN BUILDINGS 14 Energy Efficiency Highlights  More energy efficient than Standard  Renewable energy provisions  Energy measurement for verification  Electric peak load reduction SSSSWEWEEEEEIEQIEQMRMRCOCO

15 STANDARD FOR THE DESIGN OF HIGH-PERFORMANCE GREEN BUILDINGS 15 Energy Efficiency Renewable Energy Prescriptive Requirement  On-site renewable energy systems  Annual energy production equivalent of 6 KBtu/ft 2 of conditioned space  Exception for areas with incident solar radiation less than 4 kWh/m 2 -day and a cumulative purchase of green power of 70 kWh/ft 2 for a period not to exceed ten years SSSSWEWEEEEEIEQIEQMRMRCOCO

16 STANDARD FOR THE DESIGN OF HIGH-PERFORMANCE GREEN BUILDINGS 16 Energy Efficiency Prescriptive Option – Mechanical SSSSWEWEEEEEIEQIEQMRMRCOCO U.S. EPAct Baseline Use equipment with U.S. EPAct baseline efficiency levels, and: Renewable energy system producing annually 6 kBtu/ft 2 of conditioned floor space Peak load reduction of 10% Higher Efficiency Use higher efficiency of EnergySTAR requirements and Appendix C, and: Renewable energy system producing annually 4 kBtu/ft 2 of conditioned floor space Peak load reduction of 5% Equipment Efficiency Compliance Options

17 STANDARD FOR THE DESIGN OF HIGH-PERFORMANCE GREEN BUILDINGS 17 Indoor Environmental Quality Highlights  Indoor Air Quality  Ventilation rates per ASHRAE Standard 62.1  Outdoor air flow rate monitoring of minimum outside air  MERV 8 filter (MERV 13 in PM 2.5 non-attainment areas)  No smoking inside building  Source contaminant control  Daylighting  Acoustical Control SSSSWEWEEEEEIEQIEQMRMRCOCO

18 STANDARD FOR THE DESIGN OF HIGH-PERFORMANCE GREEN BUILDINGS 18 The Building’s Impact on the Atmosphere Highlights  Construction waste management  Reduced Impact Materials  Wood products  Refrigerants  Storage and collection of recyclables and discarded goods SSSSWEWEEEEEIEQIEQMRMRCOCO

19 STANDARD FOR THE DESIGN OF HIGH-PERFORMANCE GREEN BUILDINGS 19 Construction and Operation Highlights  Acceptance Testing / Commissioning  IAQ Construction Management Plan  Plans for Operation  High-performance building operation  Maintenance  Service life  Transportation management SSSSWEWEEEEEIEQIEQMRMRCOCO

20 STANDARD FOR THE DESIGN OF HIGH-PERFORMANCE GREEN BUILDINGS 20 Why Consider Adopting Standard 189.1?  The minimum green building requirements have been developed using an ANSI consensus process with four public reviews over the past three years  ASHRAE/USGBC can offer training to code officials on the detailed requirements

21 STANDARD FOR THE DESIGN OF HIGH-PERFORMANCE GREEN BUILDINGS 21 Further Information  Information on Standard 189.1:  Information on International Green Construction Code:  ASHRAE Training on Standard  User Manual is under development to assist in understanding in how to apply the standard
