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. It’s about refocusing sustainability…
…to dramatically address building operational energy use

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.

5. 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

6. It’s a methodology to hit the targets
1. Optimized thermal enclosure

1b No thermal bridging

11. 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

12. Optimized Thermal Enclosure: “Thermos”
• Continuous insulation
• No thermal bridges
• Airtight (very)
• Integration of windows
• Summer shading

• filtered
• with heat recovery
• less dust
• less pollen
• less allergies
• more oxygen
• less sleepy
• cleaner air inside than outside
