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.

It’s about refocusing sustainability…

…to dramatically address building operational energy use

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.

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

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 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

Continuous Ventilation

• low volume

• filtered

• with heat recovery

• less dust

• less pollen

• less allergies

• more oxygen

• less sleepy

• cleaner air inside than outside

Our focus: find new, holistic solutions for healthy, sustainable homes in diverse communities

James W. RouseOur founder + inspiration

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

High-energy costs contribute to financial insecurity and deprivation

42% went without medical or dental care
