WHAT IS A PASSIVE HOUSE? Passive house is the future. This building system incorporates an integrated science-based system of ultra-efficient construction combined with quality, comfort and sustainability. Most Passive Houses either have a very small mechanical heating and cooling system or none at all. This is accomplished through deep and continuous insulation, elimination of all thermal bridging, air-tight construction, triple pane windows and reducing internal loads. The net result of this effort is a 70-90% reduction in all energy costs for the lifetime of the structure. Passive Houses are so air tight that an active ventilation system is required resulting in a continuous supply of fresh and healthy outdoor air without loosing any of the heated or cooled conditioned air inside the building. Allergens and dust can be completely eliminated inside the envelope. Passive Houses tend to be very quiet providing a noise barrier to the outside. Passive Houses have been built with success in Europe since the 1980's and many building codes there have adopted Passive standards as law. An initial investment of 10-15% upfront is what we budget to bring a conventionally constructed home to the Passive Standard. Typically the larger the structure, the less the upfront cost due to surface-to-area ratio of the volume. Contact us today for a free consultation.
