4 ASHRAE Overview Founded in ,500+ volunteer members in more than 130 countries 6,000+ student members 15 regions 183 chapters 300 student branches Industry Classification Consulting engineers Contractors Manufacturers Manufacturing representatives Government, health and education Design build Architects U.S./Canada (45,000+) Global (11,000+) 4

5 ASHRAE Standard , Standard for the Design of High-Performance Green Buildings Standard provides total building sustainability guidance for designing, building and operating high-performance green buildings Has broader scope than Standard 90.1 Partners with the International Code Council (ICC) for the International Green Construction Code (IgCC) Single resource on green buildings IgCC powered by to be published in summer

6 ASHRAE Standard 188, Legionellosis: Risk Management for Building Water Systems Beneficial for those in design, construction, installation, commissioning, operation, maintenance and service of centralized building water systems and components Standard 188 establishes minimum legionellosis risk management requirements for building water systems This is the foundation of the CDC s Toolkit entitled Developing a Water Management Program to Reduce Legionella Growth and Spread in Buildings 6

7 ASHRAE Standard , Energy Standard for Data Centers Standard 90.4 was designed to ensure only the most inefficient data centers are non-compliant Is aggressive but has very achievable mechanical and electric efficiency requirements that save agencies money Data centers are often the largest energy users at an agency Works in concert with Standard

8 ASHRAE Standard , Energy Standard for Buildings Except Low-Rise Residential Buildings Standard 90.1 is a benchmark for commercial building energy codes ASHRAE has set forth efforts to address plug load reduction and help design teams account for them when evaluating building loads with Standard 90.1 Regulated loads are no longer included in a summary of energy savings in the Standard 90.1 revision in 2016 Plug loads will continue to be a critical component in achieving Advanced Energy Design Guides 8

9 Summary With the help of our industry leaders and volunteers who devote many hours of their time, we are continuously reaching our goal of providing resources to all stakeholders in the buildings industry ASHRAE has compiled an extensive webpage of resources on Advanced Energy Design Guides, which can be found at 9

10 U.S. Building Codes and Standards: Update on Changes The Whole Building Design Guide Wanda Lenkewich Chinook Systems, Inc. August 15 th, Tampa Convention Center Tampa, Florida

11 What is the Whole Building Design Guide? WBDG Celebrating 20 Years With over 500,000 users downloading 6 million documents per month, the WBDG is the only web-based portal providing government and industry practitioners with one-stop access to current information on a wide range of building-related guidance, criteria and technology from a 'whole buildings' perspective. 11

12 What is Whole Building Design? To achieve high-performance buildings It takes an Integrated Design Approach and it requires an Integrated Team Process Materials, systems, and assemblies reviewed from many different perspectives Building components, sub-systems and materials are interdependent, can impact the total performance of the whole Comprehensive Stakeholder involvement throughout the building s life cycle Evaluation for cost, quality-of-life, future flexibility, energy efficiency, overall environmental impact, productivity, creativity, and how the occupants will be enlivened 12

13 High-Performance Buildings Defined High-Performance building means a building that integrates and optimizes on a life-cycle basis all major high-performance attributes, including energy [and water] conservation, environment, safety, security, durability, accessibility, costbenefit, productivity, sustainability, functionality, and operational considerations. -Energy Independence and Security Act of (PL ) 13

18 Recommendations SUSTAINABILITY AND ENERGY SECURITY Energy independence and security are important components of national security and energy strategies. Today, power is mostly generated by massive centralized plants, and electricity moves along transmission lines. Energy independence can be achieved, in part, by minimizing energy consumption through energy conservation, energy efficiency, and by generating energy from local, renewable sources, such as wind, solar, geothermal, etc. (see WBDG Distributed Energy Resources, Fuel Cell Technology, Microturbines, Building Integrated Photovoltaics (BIPV), Daylighting, Passive Solar Heating) Additionally, using distributed energy systems adds to building resiliency as the threats of natural disaster damage become more frequent. CYBER SECURITY Building automation systems (BAS), Industrial Control Systems (ICS) and Supervisory Control and Date Acquisition (SCADA) are vulnerable to attack through the Internet. Cyber criminals can access these systems to disable controls disrupt energy and water systems and even destroy equipment. Ensure these systems are protected from these intrusions by employing cyber security measures. 18

22 U.S. Building Codes and Standards: Update on Changes Leveraging Advanced Distributed Energy Technologies for Resiliency through the IEEE 1547 Standard David Narang National Renewable Energy Laboratory (NREL) August 15, Tampa Convention Center Tampa, Florida

23 IEEE 1547 for Advanced Distributed Energy Technologies Disclaimer This presentation and discussion here on IEEE P1547 are the individual s views and are not the formal position, explanation or position of the IEEE. 23

24 Importance of IEEE 1547 Energy Policy Act (2005) Cites and requires consideration of IEEE 1547 Standards and Best Practices for Interconnection; all states use or cite Energy Independence and Security Act (2007) IEEE cited as a standards development organization partner to NIST as Lead to coordinate framework and roadmap for Smart Grid Interoperability standards and protocols {IEEE 1547 & 2030 series being expanded}; Federal ARRA (2009) Smart Grid & High Penetration DER projects {use IEEE stds}. 24

25 IEEE 1547: Interconnection is the Focus IEEE Std 1547 covers: INTERCONNECTION TECHNICAL SPECIFICATIONS & REQUIREMENTS INTERCONNECTION TEST SPECIFICATIONS & REQUIREMENTS Interconnection System Scope of IEEE Std 1547 Distributed Energy Resource (DER) Communication Interface Power Interface Area Electric Power System (Area EPS) Note: P1547 full revision started in year 2015 is also addressing interoperability and interfaces interconnection system: The collection of all interconnection equipment and functions, taken as a group, used to interconnect DER to an Area EPS. NOTE Besides the power interface, DER shall have a communication interface. interface: A logical interconnection from one entity to another that supports one or more data flows implemented with one or more data links interoperability: The capability of two or more networks, systems, devices, applications, or components to externally exchange and readily use information securely and effectively.` 25
