These are coupled with energy-efficient appliances and lighting systems to minimize consumption. Through careful planning and innovative technologies, net-zero energy homes are not only environmentally friendly but also economically beneficial, offering homeowners long-term savings on utility bills. Sustainable housing was once a niche concept, but it has moved its address to the front lines of architectural innovation and urban planning. With an increased emphasis on conserving resources, reducing carbon footprints and promoting healthier living environments, sustainable housing trends are influencing the way homes and communities are being built. Instead, Passive Houses keep the air fresh through a system known as ‘mechanical ventilation’. This is where a heat recovery ventilator (HRV) continuously removes old or moist air and delivers fresh air.

If sound concerns are critical due to building location (i.e. locations next to a freeway, airport) additional material selections can be recommended and included to reduce noise. The four-storey building, which looks like a two-storey home from the front, is super-insulated and complete with a heat recovery ventilation system that retains warmth to ensure it performs to Passivhaus standards. The ERV system is not just a feature; it’s a testament to the ingenuity of passive house design.
What is a Passivhaus?
A zero-carbon future starts right here with our locally tailored, globally applicable passive building standards. By combining individual measures any new building anywhere in the world can be designed to reach the Passive House Standard. The versatile Passive House Standard is also increasingly being used for non-residential buildings such as administrative buildings and schools. Education on the design of passive house buildings is available on a global level with a lot of different professional trainers.
"Tiny homes are not the big solution to homelessness that we need"
These houses exemplify a commitment not just to sustainable homes but also to creating spaces that nurture and protect the health of their occupants. The dedication to creating airtight spaces is emblematic of a philosophy that goes beyond the mere physical structure. It embodies a profound commitment to the holistic well-being and contentment of the individuals who call the passive house their home. Led by the Phius Technical Committee, our team conducts cutting-edge research to continue the advancement of Phius and passive building. Understanding Passivhaus by Emma Walshaw of First In Architecture is a brief, clear, and complete guide to Passivhaus homes. Fundamental principles for all aspects of the enclosure are elegantly introduced and illustrated before 8 common Passivhaus building assemblies are presented and showcased in case studies.
It is perfectly possible to design beautiful buildings that serve their desired purpose, while being sustainable, comfortable and energy efficient. The Passivhaus reduces energy demand by up to 90% compared to normal buildings and is therefore minimising energy consumption and carbon emissions into the atmosphere. The Passivhaus standard, developed in Germany, by Wolfgang Feist, a physicist with a passion for low energy building research and design.
In warmer months, adjustable shading elements on south-facing windows prevent the house from overheating. Although passive house design was born in the 1970s, it is becoming more top-of-mind as homeowners across the country face climate-related challenges. Here are some of the positives and negatives to evaluate when considering either purchasing a new home with passive house design or deciding to retrofit a current home to meet those standards. Indoor humidity is kept at a safe, comfortable level by choosing the best mechanical systems possible.
For this reason, using energy efficient windows is vital in achieving Passivhaus standards. This means using windows that are as high quality as possible, to prevent the serious heat loss that can so often occur. The Passivhaus standard uses the precision of building physics to ensure reduced energy costs and demand, comfortable and healthy living conditions, with a high standard of energy efficiency that exceeds government regulations. Superior indoor air quality is provided around the clock via a fresh air system with air filters and heat-recovery ventilation (HRV). This is due to the fact that people, on average, emit heat equivalent to 100 watts each of radiated thermal energy.
PASSIVE HOUSE will maintain comfortable interior temperatures for extended periods of time. Due to low energy usage, onsite renewable energy and power backup storage, your home will be a comfortable and healthy place for you and your family during a power outage or time when to shelter in place. In the rural surrounds of the Scottish borders, this beautiful example shows that a Passive House doesn’t mean you can’t have plentiful windows and light. As long as they’re good quality, it’s possible to maintain the superinsulation that keeps these homes so stable when it comes to temperature. Read on to find out more about homes built to Passive House standards, and how in the long run they could reduce your energy bills, as well as your carbon footprint. An ever growing number of initiatives introduce passive house design all around planet Earth.
Yes, conceptually, an existing structure can be retrofitted to conform to passive house standards. The process could involve building an outer shell around the entire house (wall and roof), but this isn’t always possible. There’s a more attainable standard called EnerPHit, a version of passive house design for retrofits of existing buildings.
The space between glazing layers is often filled with inert gases such as argon or krypton in order to minimize heat loss. Sandi Schwartz is an environmental author and freelance journalist with over 20 years of extensive experience communicating science-based information to diverse audiences in the areas of sustainability, home/garden, green living, nature, and wellness. To effectively create a Passive House building, the design should be looked at holistically to incorporate all five design principles. Building orientation and form are fundamental design decisions that set the stage for how easy or difficult it will be for a building to achieve Passive House performance. No, they aren’t bound to any specific style, but they have defining features, such as thick walls (which allow for super insulation) and triple-glazed windows. Design-wise they take many forms, from traditional to modern and from simple to complex.

As the design editor, I am compelled to remark that in addition to their performance and affordability attributes, the houses are also really good looking. They are modest in size, rich in architectural interest, and regionally appropriate—a winning combination.
Passive House designs are also resilient and can act as “thermal batteries,” so if the electricity goes out they can maintain their internal temperatures for days or even weeks. Thoughtful, thermal-bridge-free enclosure design eliminates "cold corners," minimizes risk of mold growth on the interior, and improves comfort. You don’t need special furniture, but to meet all the requirements for Passive House status, you do need to check your furniture, and even the paints you use to decorate your home. This relates to indoor air pollution, as there are limits on volatile organic compounds (VOC) in the home, which affect the quality of the air.

One important goal of the Passive House Standard is to minimize the total primary energy consumption. I have seen passive house projects that use propane for heating, for example, and they are able to meet the requirement, but this is a bit of a cheat. We also have solar panels in a field adjacent to our house and recently signed on to receive power from wind farms. Yes, passive house construction is estimated to cost 10 to 15 percent more than standard building costs. That said, by slashing energy costs, passive houses save owners considerably over time.
Additionally, in partnership with Indigenous Design Studio + Architecture (IDS+A), $24 million from the American Rescue Plan Act will be used to expand ZenniHome’s production by building a second factory next to its first one near Page, Arizona. Green roofs and vertical gardens are transforming urban landscapes by adding greenery to densely populated areas and mitigating the heat-island effect. That’s not to say it’s not worth thinking about renovating your home to a Passive House design – but it may be more complicated, and difficult to reap quite so many rewards. Passipedia constitutes a vast array of cutting edge, scientifically sound, Passive House relevant articles. On Passipedia, basic Passive House information and insights are available for all to see, whereas members of the International Passive House Association (iPHA) receive special access to the more in-depth sections. As a start, we recommend the video embedded on the right “Passive House Explained in 90 Seconds” by Hans-Jörn Eich (Video under creative commons license "Attribution-NonCommercial-ShareAlike 4.0 International (CC BY-NC-SA 4.0)).
Passive House designs can look like any conventional building, although to minimize thermal bridges, they are often simpler and boxier minimalist forms. The airtight building layer is one of the most critical features of a Passive House, as the amount of air infiltration is strictly limited to 0.6 air changes per hour under PHI standards. It is built up with membranes and tapes carefully installed, then tested with a blower door. Passive buildings require special attention to moisture control both in proper vapor and moisture control design for the enclosure as well as the mechanical systems needed to maintain appropriate moisture levels in the space.
The PHI standard applies the same criteria anywhere in the world; the PHIUS standard varies slightly according to location. With increasing concerns about climate change and urbanization, Passive House designs can now be found on every continent, including on Antarctica. In addition, thermal control involves installing well-insulated windows that qualify as passive house windows to prevent heat transfer. It also entails removing thermal bridges throughout the home to avoid cold corners, minimize mold growth, and improve overall comfort. Finally, in 2015, PHIUS released the PHIUS+ standard that considers cost-effective and climate-specific performance criteria.
