NASA Net Zero Roadmap: Federal Utilities Partnership Working Group, November 2014

A summary presentation of NASA's Net Zero Roadmap. The roadmap, available at http://www.nrel.gov/docs/fy15osti/60838.pdf, provides strategic, operational, and tactical level proficiencies necessary for NASA to implement to successfully reach net zero by 2020. Slides posted at FUPWG's site at http://energy.gov/eere/femp/downloads/fupwg-fall-2014-agenda-and-presentations.

Executive Order 13514 Goals “… establish an integrated strategy towards sustainability in the Federal Government and to make reduction of greenhouse gas emissions a priority for Federal agencies…” (Preamble) “… implement high performance sustainable Federal building design, construction, operation and management, maintenance, and deconstruction including by: (i) beginning in 2020 and thereafter, ensuring that all new Federal buildings that enter the planning process are designed to achieve zero-net-energy by 2030 …” (Sec. 2. Goals for Agencies. (g)(i))

  • 6. NASA NZEBs Roadmap Structure To guide NASA’s incremental transition to developing and operating NZEBs as Agency standard practice Strategic – Established clear interpretation of EO 13514 sections related to NZEBs Organizational Proficiencies – Identified 6 key proficiencies essential to NASA’s transition to NZEBs Tactical – Prioritized 57 tactics for Agency-level and building-level transition Proficiency Tactic Count Purpose NZEB Workflow 8 Integrate roadmap into current processes Acquisition Process 12 Use energy performance-based acquisition Energy Efficiency 20 Require overall efficiency and system focus Renewable Energy 6 Phase-in renewables second to efficiency Operations 9 Develop operation effort unique to NZEBs Achieve NZEB 2 Deploy in design/construction & operation
  • 7. Application of Executive Order 13514 For NASA NZEB definition: annual operational, site energy goal for new buildings • Step 1. Best-in-class energy efficiency (EE), demand-side energy use intensity (EUI) 50% reduction versus AHSRAE Standard 90.1-2010 starting in 2020 • Step 2. Maximize zero-emitting roof/building-integrated RE All buildings meet a minimum 20% of the RE requirement at this step • Step 3. Maximize zero-emitting site/center RE All low-load buildings should meet NZEB design at this step • Step 4. Consider on-site generation from imported offsite RE Evaluate current federal requirements and benefits beyond NZEB compliance, and perform a greenhouse gas LCA with guidance from EMD • Step 5. Consider purchase of regional utility “green power” Invest in newly installed offsite RE
  • 8. NZEB Proficiencies for NASA
  • 9. CP-1: Institutionalize NASA NZEB Workflow • Implement NASA NZEB Roadmap • Annual Tracking of progress toward NZEB Goal • Implement pilot projects to develop proficiencies in NZEB methods – Develop NZEB ongoing pilot review and lessons learned through their existing POE process – Standardized strategies and NZEB project workflows – NASA NZEB design guidelines • Agency oversight for time-phased NZEB program rollout – Communicate successes – Understand status
  • 10. OP-1: NZEB Acquisition Process • Develop a standardized way to incorporate NZEB targets for EE and RE into new construction contracts – Integrated Project Delivery (IPD) Requirements – Energy-performance based Design-Build specs • Emerging best practices for incentivizing NZEB Operations – Successful M+V required in design-build contract – 1 year of verified performance? • Energy modeling tools to predict energy performance and drive design decisions
  • 11. https://buildingdata.energy.gov/cbrd/energy_based_acquisition/
  • 12. OP-2: Energy Efficiency Best Practices • Target 50%+ demand side savings – www.ashrae.org/aedg – Note 30% savings over 90.1-2010 now required • Focus on simple and passive solutions first – Massing – Orientation – Glazing amount and orientation • Load reduction design next – Invest in a high quality thermal envelope • Continuous insulation system • Air barrier requirements WITH whole building airtightness testing – Solar gain shading – Expect to provide glare free daylighting across 75%+ floor space – Aggressive plug load reductions
  • 13. OP-2: Energy Efficiency Best Practices • Efficient Active Systems – Dedicated outside air with hydronic distribution • Demand controlled outside air with exhaust air energy recovery • Say NO to reheat – Full LED electrical lighting with fixture based sensor and controls • Controls – Vacancy sensors throughout for lighting controls – What can be turned OFF at night?
  • 14. OP-3: Renewable Systems Integration • Balance efficiency costs with renewables cost • PV ready building design – Expect to maximize roof area for PV – Minimize shading – Streamline installation – Plan for site based PV • Parking • Ground mounts • Financing – Third-party owned? – On-site vs. off-site – Replacement RECs • Allocation of new renewables to new buildings
  • 15. Renewable Integration at NREL
  • 16. OP-4: NZEB Operations Plan • Who is responsible for NZEB? – Reporting and “NZEB Commissioning” • Dashboards and informatics that work – Submetering that is used real-time • NZEB Occupants – Training – Occupant loads – Administer change management • NZEB Contingency plan – 10-20% extra PV – Ongoing load growth management • Is it the most efficient way? • Do we have extra PV? • Plan for future PV for additional offsets
  • 17. NZEB Dashboards
  • 18. NZEB Dashboards
  • 19. NZEB Dashboards
  • 20. CP-2: Define Agency Metrics for Tracking Progress • Time-phased rollout of NZEB method – NZEB procurement – NZEB design and construction – NZEB operations • Successfully rollout of NZEB tactics : – Train, – then pilot, – then learn, – then institutionalize!
  • 21. Time-Phased Approach
