Along with higher indoor air quality and more comfortable indoor temperature ranges, buildings designed and built to meet the Passive House Standard typically see a 75-90% reduction in energy use and a much lower carbon footprint when compared to traditionally constructed buildings. This is a true leap forward in design, particularly as there is no need for expensive or cutting technologies to achieve these amazing results. These inherent advantages are important today, and will be even more important as energy prices continue to rise in the future.
In our quest to produce better buildings and improve the building stock in the US, staff from Newhouse Development have attended the Passive House Consultant training courses and are actively involved in planning several projects that are to be built and certified to meet the Passive House Building Energy Standard.

Although it has been in existence in Europe since 1990, the Passive House Standard was introduced to the US in 2008 and has gained rapid acceptance since that time. Recently, several states and localities adopted it as an optional performance target and the US Congress has been discussing legislation that would provide incentives to builders and developers who voluntarily meet the standard. In addition, both the US Green Building Council and the National Association of Homebuilders are in the process of incorporating the Passive House Standard into their green building guidelines.
Although called "Passive House buildings", these structures are actually designed to actively improve the indoor spaces that we inhabit as we live, work and play. The example charts shown below clearly illustrate the dramatic differences between a Passive House building (on the left) and a typical older building (on the right). As the ambient temperature (the blue line below) fluctuates over an eight day period, the Passive House building maintains an almost constant indoor temperature (requiring much less energy for heating and cooling). At the same time, the indoor temperatures in the older building follow the changes in the outdoor temperature almost identically, requiring far more energy to offset the constant swings in temperature, creating a very uncomfortable space to be in and potentially a sick building.
Check out the following video, which discusses the "SmartHome" Passive House project being sponsored by the Cleveland Museum of Natural History.

Typical older building
These measurements were taken in July, in a hot climate (Seville, Spain) and while the Passive House building maintained an indoor range of 76-80°F, the older building had an indoor range of 80-97 °F.
The Passive House Building Energy Standard Since our founding in 2003, Newhouse Development has been focused on building higher quality, healthier and more energy efficient buildings. In 2010, we took this commitment to the next level by adopting the efficiency targets set forth by the Passive House Building Energy Standard.
The Passive House Standard is a non-prescriptive building approach with very strict technical requirements for air tightness, energy efficiency and prevention of thermal bridging. The end result is a healthier, more comfortable and much more energy efficient structure, which can be built (or renovated) at a cost that is only slightly higher than traditional construction - while producing building performance results that far exceed the added initial investment.
