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

It’s about refocusing sustainability…

…to dramatically address building operational energy use

Page 3: July2013 ghnyc -alternatives to leed

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.

Page 4: July2013 ghnyc -alternatives to leed
Page 5: July2013 ghnyc -alternatives to leed

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

Page 6: July2013 ghnyc -alternatives to leed

It’s a methodology to hit the targets

1. Optimized thermal enclosure

1a Continuous insulation

1b No thermal bridging

1c Air tightness

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

Page 12: July2013 ghnyc -alternatives to leed

Optimized Thermal Enclosure: “Thermos”

• Continuous insulation

• No thermal bridges

• Airtight (very)

• Integration of windows

• Summer shading

Continuous Ventilation

• low volume

• filtered

• with heat recovery

• less dust

• less pollen

• less allergies

• more oxygen

• less sleepy

• cleaner air inside than outside

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
