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.
![Page 2: July2013 ghnyc -alternatives to leed-7-17-13](https://reader034.vdocuments.us/reader034/viewer/2022051400/54bf82044a79599e298b456f/html5/thumbnails/2.jpg)
It’s about refocusing sustainability…
…to dramatically address building operational energy use
![Page 3: July2013 ghnyc -alternatives to leed-7-17-13](https://reader034.vdocuments.us/reader034/viewer/2022051400/54bf82044a79599e298b456f/html5/thumbnails/3.jpg)
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.

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
![Page 6: July2013 ghnyc -alternatives to leed-7-17-13](https://reader034.vdocuments.us/reader034/viewer/2022051400/54bf82044a79599e298b456f/html5/thumbnails/6.jpg)
It’s a methodology to hit the targets
1. Optimized thermal enclosure

1b No thermal bridging
1c Air tightness
1d Windows
2. Optimized passive heat gains

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

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