Reducing Emissions By Switching To A New Building Technology

Erase40’s mission is to develop market-based initiatives that result in the widespread adoption of a low carbon building technology called Passive House.

Adopting this technology may be one of the easiest and least costly ways to greatly reduce carbon emissions around the world. Buildings are responsible for approximately 40% of all carbon emissions in the U.S. and globally, but a switch to this low carbon building technology can reduce this number drastically.

Widespread adoption of this technology would also reduce people’s exposure to air pollutants and lower their monthly energy and repair costs.

What is Passive House technology?
It’s a rigorous, performance-based building method that reduces energy needs of a building and increases the amount of fresh air circulating inside that building. The buildings are designed using models that incorporate regional weather data so that they are built to withstand conditions specific to that area. The result are buildings that are more resilient and less costly to own.

7 Reasons
This Technology Is A Good Way To Reduce Emissions


Technology exists now, not years away


The technology is performance based and inexpensive


No shift in the public’s attitudes about climate change required


No large investments in infrastructure required


No major changes to the economy required


Applicable to all regions and all building types


Capable of reducing a major contributor of emissions to nearly zero

The Mission

Drive the widespread adoption of passive building technology through the development of targeted market-based initiatives.

  • Consumer education
  • Behavior change programs
  • Community organizing and outreach
  • Educating elected officials and policy makers

Change what people expect from a building

A number of behaviors are complicit in the acceptance of the risks and costs associated with conventional buildings. Erase40’s initiatives will target these behaviors and lower the barriers to adoption. These initiatives will decrease the tolerance of owners, occupants and funders for the costs and risks associated with conventional buildings, such as financial uncertainty, high ownership costs and exposure to air and external noise pollution in their homes.


The result of widespread adoption of this technology?

  • A significant reduction in CO2 emissions
  • Fewer people with chronic exposure to air pollutants
  • Reduced ongoing costs for renters and households
  • Fewer people under financial stress from high heating costs

5 Populations

The burdens of conventional buildings fall particularly heavy on the shoulders of five populations. These people would benefit immensely from the widespread adoption of this technology.


Adults and children exposed to persistent noise. People in certain neighborhoods live with high levels of noise that can interfere with their ability to focus or sleep. Passive buildings are far quieter than conventional buildings and can greatly improve this situation.


Recipients of energy assistance. Millions of households receive energy assistance each year but funding for this program is being reduced over time and so the eligible for assistance far exceeds the number of people to received this assistance.


People with respiratory conditions: There are over 23 million people in the U.S. with asthma. Chronic exposure to pollutants in a person’s home can result in frequent aggravation of that condition—and loss of sleep, missed workdays and emergency room visits.


Children exposed to pollution at developmentally important periods: According to the EPA, the air quality in homes is, on average, two to five times worse than outdoor air and can be as much as a hundred times worse than outdoor air. This can be particularly harmful to children under the age of five.


Low income populations: Low income populations are disproportionately affected by high fuel costs, substandard construction practices and exposure to air and noise pollution.
