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.

The clear & limited targets counter-intuitively ensure success of broad
objectives
6. 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

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

13. Continuous Ventilation
• low volume
• filtered
• with heat recovery
• less dust
• less pollen
• less allergies
• more oxygen
• less sleepy
• cleaner air inside than outside

Affordability
Stronger communities
Greater safety
Investment opportunity
Local prosperity
Better health
Improved comfort
Reduced utilities costs
Improved air & water quality
Protection of environmentally sensitive areas
39. Our focus: find new,
holistic solutions for
healthy, sustainable
homes in diverse
communities
41. 65 million live in overcrowded or
substandard housing
There are 25 million households with annual
incomes of $25,000 or less
They pay 4 times as much of their monthly
household income on utility bills
Households in the
United States
42. High-energy costs
contribute to financial
insecurity
and deprivation
42% went without medical or dental care
20% went without food for a day
