What is Passive Building Phius What is passive house or passive building?

In some cases a micro-heat pump is used to extract additional heat from the exhaust ventilation air, using it to heat either the incoming air or the hot water storage tank. Small wood-burning stoves can also be used to heat the water tank, although care is required to ensure that the room in which stove is located does not overheat. The world's tallest "passive house" was built in the Bolueta neighborhood in Bilbao, Spain. At 289 feet (88 m), it is currently the world's tallest building certified under the standard in 2018. The $14.5 million, 171-unit development (including a nine-story companion to the high-rise) consists entirely of social housing.

Ventilation and Heat Recovery

Keep reading to discover more about passive house design and how it can effectively align with energy efficiency in the home. The Phius standards guide the successful design and construction of passive building structures worldwide. Passive design is a holistic approach that takes every last factor into account, down to heat emissions from appliances and occupants. The best way to build passive is the Phius standard and accounts for the overwhelming majority of passive buildings in North America. Proper mechanical system selection and commissioning is critical to maintaining comfortable and safe moisture levels inside passive buildings.

Of particular interest is the fact that the homes can stand alone or be stacked up to five stories high, offering an ideal solution for developers building multifamily projects. Each home is steel-framed and features robotic walls and furniture to capitalize on the available space, with each room serving multiple purposes. Additional sustainable features include solar integration — reducing reliance on the traditional power grid — and plumbing systems that separate gray and black water — promoting efficient water use and reuse. Residents benefit from great indoor air quality, comfortable and even temperatures, significantly reduced energy bills and acoustically superior homes from reduced noise attenuation from neighbors and street noise. To meet the certification standards of a passive house, homes must be built to the best possible standards.

Unmatched Comfort

Superior indoor air quality is provided around the clock via a fresh air system with air filters and heat-recovery ventilation (HRV). While many people assume that passive house design is only for new home construction, this is simply not the case. Homeowners working on a remodeling project can upgrade their house to meet the passive design standards.

Learn how you can build comfortable, healthy, cost-efficient buildings for a more resilient world. Passive solar building design and energy-efficient landscaping support the passive house energy conservation and can integrate them into a neighborhood and environment. However, the use of solar gain, especially in temperate climate regions, is secondary to minimizing the overall house energy requirements. In climates and regions needing to reduce excessive summer passive solar heat gain, whether from direct or reflected sources, brise soleil, trees, attached pergolas with vines, vertical gardens, green roofs, and other techniques are implemented. A passive house is built to much higher energy efficiency standards than a conventional building.

The most common thermal bridge is a gap in insulation, but outlets, junction boxes, and plumbing can also act as thermal bridges. Thermal bridges are more common at corners, jogs, balconies, and discontinuities, which is why Passive House designs tend to be simpler. The annual specific heat demand for the zero-heating house should not exceed 3 kWh/m2a. Zero heating building is generally considered to be simpler to design and to operate as there is no need for modulated sun shading. A disadvantage resulting from the thickness of wall insulation required is that, unless the external dimensions of the building can be enlarged to compensate, the internal floor area of the building may be less compared to traditional construction. The specific heat load for the heating source at design temperature is recommended, but not required, to be less than 10 W/m2 (3.17 btu/(h⋅ft2)).

Typical buildings consume up to 40 percent of global energy use and contribute up to 30 percent of annual global greenhouse gas emissions and are contributors to climate change. With Passive House standards you will enjoy comfort, exceptional indoor air quality, and a healthy sustainable home with low utility bills. The PASSIVE HOUSE Standard offers a solution towards a low-carbon future for residential and commercial building. Phius is the smartest path to a zero-carbon built environment, certifying the majority of all passive house projects in North America with our locally tailored, globally applicable passive building standard.

The Passive Performance Standard for Better Living

As sustainable living continues to be an important topic of discussion in the United States, homeowners are increasingly looking for ways to make their homes more energy efficient. Saving money on utility bills and enjoying a more comfortable living environment are rewarding personal advantages, but the benefits of a green home extend far beyond one’s own front door. You’ll need a Roomba to make that final part of the dream come (partially) true, but there’s a type of home that’s practically Jetsons-like in its attention to conservation and efficiency. Avoiding thermal bridges, weak points in the building envelope, contributes to pleasant, even interior temperatures while eliminating moisture damage and improving energy efficiency. In addition, thermal control involves installing well-insulated windows that qualify as passive house windows to prevent heat transfer.

This means that it requires less energy to heat or cool the building, reducing its environmental impact and long-term costs. These living infrastructure elements not only provide aesthetic value but also offer numerous environmental benefits, such as improving air quality, reducing stormwater runoff and enhancing insulation. By incorporating vegetation into building design, sustainable housing projects can harmonize with nature and contribute to the creation of more resilient and livable cities. There have been schools, kindergartens, and a supermarket, all built according to Passivhaus standards. Instead, it gets energy from solar hot water collectors, and processes water through a built-in water treatment system. It also has a heat recovery ventilation system, EPS insulation, and IKEA furnishings.

"It might cost you $70,000 a year to have a middle-class retirement in the United States," Sikes says. "If you have that money in southern Italy, you can live like a king, including renting or purchasing a property."

90%; since then, lots of realized passive houses have been monitored with convincing results. In other words, the Passive House is a “factor 10 house” which only uses one tenth of the energy used by average houses.

This is good news for buyers, as you’ll likely have less work to do on your newly purchased home to make it more comfortable and carbon-friendly. “It’s a set of principles that puts conservation first to reduce the amount of energy it takes to heat and cool a building to measurable comfort levels,” explains Michael Knezovich, the Communications Director at Passive House Institute U.S. (PHIUS). Because passive homes are achieved through construction technique, the term “passive house” is arguably limiting — nearly any type of building can be passive, from single-family homes to skyscrapers.
