With the growing movement of embracing sustainability in design and architecture, passive houses have started to become more widespread. Designed according to strict principles, these passive homes require a bigger investment up front, but offer significant energy savings and low energy consumption to offset this over a relatively short period of time. These living spaces are also more comfortable as they have better air quality and almost constant indoor temperatures. While in the past, passive houses often compromised design for energy efficiency and durability, now they come in a range of inspiring styles. We have curated a list of our favorite passive houses designs that showcase the incredible creativity, ingenuity, and love of sustainability of architects from the US and around the world.
What makes a house passive?
To achieve the Passive House standard and receive the certification, a building needs to fulfill certain conditions. Apart from eliminating thermal bridges, the house needs to achieve thermal comfort with minimal energy consumption, heating and cooling. Insulation, an airtight construction, efficient glazing, and a ventilation system with heat recovery are also included in the list. The living areas also need to maintain temperatures of 20-25° consistently, for most of the year. These highly efficient buildings use significantly less energy than standard buildings, and usually incorporate at least one source of renewable energy.
What are the disadvantages of a passive house?
While highly energy efficient, a passive house has some disadvantages. Among them, the higher costs of building a new house or to retrofit an existing one to the required building standard. The necessary glazing alterations can also affect the size and design of the openings, along with local weather conditions throughout the year. Residents also need to learn to operate the systems’ controls and often have a backup heating and cooling system.
What are the 5 principles of passive houses?
All passive houses incorporate five crucial features in their design. Apart from no thermal bridging, they have excellent insulation, an airtight build, and high performance windows and glazing. Additionally, they have mechanical ventilation systems with heat recovery. All of these features ensure that the living spaces achieve optimal thermal comfort and minimize energy use. To receive the certification from the Passive House institute or an accredited company, a passive house design needs to go through various tests, including the blower door test that ensures the building has an airtight construction.
Is a passive house worth it?
A passive house is not only significantly more eco-friendly than a standard house, but it also helps to greatly reduce energy use and thus offer energy savings. These passive house buildings and passive homes are incredibly efficient and comfortable, with temperatures remaining almost constant at least 90% percent of the year. The efficient ventilation also ensures a better indoor air quality and fresh air indoors. As for downsides, a passive house is harder to redesign, with any changes having to take into account the core principles of the Passive House standard. Additionally, indoor temperature largely stays constant, meaning that the residents can’t make the interiors too cool or too hot if they wish to do so.
Who invented the Passive House?
The first mention of the “passive house” term dates to 1982, when American physicist William Shurcliff wrote about the concept in his book The Saunders-Shrewsbury House. In the late 1980s, German physicist Wolfgang Feist further developed the concept and created an efficient passive house design. Later, he founded the Passivhaus Institute, which still provides the only internationally recognized, performance-based energy construction standard. Officially, the first passive house was built in 1991, in the city of Darmstadt, Germany.
The House in the Forest
A quiet home built at the edge of a national park.
Nestled in the middle of nature at the edge of the Garraf Natural Park in Spain, this is one of the passive houses that celebrate their surrounding landscape. Architecture firm El Fil Verd designed the dwelling as a detached, single-family home. The build incorporates sustainable architecture principles. Embedded in the site, the volume follows the topography of the terrain and opens to views of the park and mountains. The studio used aerated concrete blocks for the envelope to keep the building light but insulated. Thermo-treated cork panels, lime and silicate paint finishes, solid pine wood, and quartz are among the other materials used for this project. The carefully chosen openings and the house’s orientation ensure optimal passive ventilation, heating and cooling throughout the year. Other details include newly planted deciduous trees and a rainwater collection system.
