  1. 1. Alternatives to LEED: Passive House An International Building Energy Standard Presented By: New York Passive House A local non-profit affiliated with the Passive House Institute.
  2. 2. It’s about refocusing sustainability… …to dramatically address building operational energy use
  3. 3. Passive House is about broad objectives Health: Indoor air quality, most healthy Comfort: Thermal control, most comfortable. Energy: Up to 90% reduction heating and cooling. Affordability: Modest upcharge / dramatic utility savings. Predictability: Data driven energy design, based on real world results. Resiliency: Safely shelter in place without heat.
  4. 4. Passive House has very clear targets An absolute energy target and air-tightness requirements. Representing a 95% reduction in heating energy demand from current NYC building stock. PHPP verification page snap shot The clear & limited targets counter-intuitively ensure success of broad objectives
  5. 5. It’s a methodology to hit the targets 1. Optimized thermal enclosure 1a Continuous insulation 1b No thermal bridging 1c Air tightness 1d Windows 2. Optimized passive heat gains Passive solar Occupants Appliances 3. Optimized ventilation High efficiency ERV 4. Supplemental heating / cooling Careful not to oversize 5. Energy efficient systems Lighting DHW Appliances + + + SecondaryelementsPrimaryelements EnterallintoPHPP
  6. 6. 1990: First Passive House
  7. 7. Quality Assured Certified Passive House Energy Model Methodology Certified Components Trained Professionals
  8. 8. 2000: Verification of Methodology
  9. 9. Brussels 2007-2011: From 0 to 3.5 mill sq feet • In 2015 all buildings must meet Passive House standards private, public, new and retrofitted. Exemplary Buildings In 5 rounds Stimulate demand Share know-how Measure results Make Passive Typical
  10. 10. Passive House Planning Package (PHPP) • energy model • optimized from real world data collection • complete data results provide better understanding of building dynamics • highly predictive • without the PHPP you can not design a Passive House
  11. 11. Optimized Thermal Enclosure: “Thermos” • Continuous insulation • No thermal bridges • Airtight (very) • Integration of windows • Summer shading Building section diagramWindow Section Blower Door Test Eliminate Thermal Bridges
  12. 12. Continuous Ventilation • low volume • filtered • with heat recovery • less dust • less pollen • less allergies • more oxygen • less sleepy • cleaner air inside than outside Counter-Flow Heat Exchange
  13. 13. with Reduced Mechanical Systems 75% sizing reduction Simplified operation
  14. 14. Other Energy Efficient Systems Domestic Hot Water: efficient fixtures high efficiency water heater solar thermal option Lighting: efficient fixtures simple controls Appliances: efficient appliances simplify, simplify, simplify…
