© What's Passive about that? Passivhaus Institut
The entirety of the EuroClime standard product line is suitable for use in passive houses. The less insulative products will likely require for the aggregate glazing amount to be moderate relative to the square footage of the conditioned space. Using higher insulative products will allow larger expanses of glass and/or less envelope insulation. Some of our higher-end products even carry the prestigious Passivhaus Institut certification for fenestration. EuroClime is especially pleased to be able to offer aluminum and steel window/door systems that can meet passive house design requirements. These rare metal products can have great appeal to the light commercial market.
We truly believe that our clients should not overbuy in terms of product needs, especially if the goal is not to meet full passive house standards, but rather to find a value solution that balances performance and cost.

The Passive House Ideal
The root design principals of passive houses have been around for a very long time and have been practiced in part by architects and builders for many decades and even centuries. It wasn't until the Germany-based Passivhaus Institut (PHI) was formed circa 1990 that a rigorous methodology and design standard was formalized. Today, passive house design is practiced throughout the world, and is gaining an increasingly prominent presence in North America, especially with the diligent advocacy of the Passive House Institute US (PHIUS), and the local regional organizations such as Passive House NorthWest (PHNW).
In passive house design, buildings are required to use a very small prescribed amount of energy for their environmental control needs, mainly in heating and cooling. To achieve this, passive houses have to be deliberately designed to have a very high level of insulation combined with exacting construction techniques that ensure a highly airtight building envelope. As much as possible without using mechanical means, winter-time heating requirements are mostly met through passive solar gain from carefully oriented windows, doors, and skylights. Even the waste heat generated by people and electrical equipment are accounted for in the analysis. Summer-time cooling is usually designed for using the passive shading of direct sunlight, and ideally with very little or no mechanical air conditioning.
Since passive houses must be extremely well-insulated and near airtight, the fenestration used in them must be of also highly insulative and airtight since even the best windows and doors are relatively energy- wasting compared to floors, walls, and roofs. Products from North America are usually insufficient to meet the passive house requirements, and those that do, are usually too expensive for most. Passive house designers trying to incorporate less thermally efficient fenestration into their buildings typically find that it is too expensive to compensate with thicker walls and roofs. Due to this economic issue and the unmet need that it creates, EuroClime and our friendly competitors are proud to bring European windows and doors to the North American market as a service to the burgeoning passive house community. We hope that by doing so, we will benefit of all domestic homeowners and the environment in general.
