passive house design

Its space heating requirement is 9 kilowatt-hours per square metre – exceeding the level required to receive Passivhaus certification from the UK's Passive House Organisation. The Passivhaus creates an internal environment that is comfortable in both summer and winter. It will have no draughts, no cold surfaces or down-draughts at the windows and will have good indoor air quality. Passivhaus is likely to benefit asthma sufferers and those with respiratory conditions. The building envelope is what separates the interior of the building from the exterior; it consists of outside walls, roofs, and floors. In cold climates like Canada, where inside air is heated to keep the building comfortable, some of that heat will be lost as it moves through the envelope (via the process of conduction).

Everything you need to know about Passive House certification

A passive house (“passivhaus” in German) is a design standard that delivers healthy, comfortable, and efficient homes using a holistic approach. Essentially, these homes heat and cool themselves, cutting energy bills by about 90 percent. Homeowners often report that they don’t even have to turn on their heat during the winter because of the way their passive house is designed.

Due to their function (providing light and visibility), glazing systems cannot be insulated to the same degree as a wall, resulting in the windows being the weakest areas of the envelope in terms of heat-flow resistance. Therefore, it is very important that high-performance glazing systems, such as Passive House-certified windows, are used to reduce that heat flow as much as possible. It’s being rigorous with the installation details that you need to achieve the performance standard. You can spend a lot of time and money making energy-efficient choices, but if they aren’t installed well, it’s wasted effort. The proper way to build to the Passive House Standard involves working with a passive house consultant.

Plus, you’ll make savings in the construction process – for instance, by not needing to spend money on a central heating system. Another important aspect of the ‘envelope’ is airflow – as this is another way the protective bubble of insulation can be compromised. It means that you need to pay close attention to airflow at the design stage, as well as using high-quality construction. It represents a fundamental shift that goes beyond conventional building methods and heralds a new era where residences are not just physical structures but also guardians of the natural world. As you delve into this article, come to recognize their capacity for fostering a more eco-friendly, comfortable, and sustainable global habitat for everyone.

Are passive house materials environmentally correct?

As the demand for sustainable housing continues to grow, so too will the innovation and creativity driving this transformative movement toward a more sustainable and harmonious built environment. By leveraging the power of artificial intelligence and data analytics, smart homes can adapt to occupants’ preferences and environmental conditions to maximize efficiency and comfort. Integrating smart home technologies into sustainable housing allows for greater control and optimization of energy usage. Stay informed on the Passive House building standard, project developments, upcoming events and courses.

Students in a design-and-build programme at the University of Kansas designed this house to offer "an example of the way housing can be done more responsibly in the future". In 2019, London studio Mikhail Riches and architect Cathy Hawley won the Stirling Prize for a social housing scheme in Norwich that helps tackle fuel poverty by meeting Passivhaus standards. At the time, sustainable architecture studio Architype said the win "puts Passivhaus in the spotlight – exactly where it needs to stay". Is an architectural workshop for environmental design ideas, a concept-drive studio for converting site, program and client needs and desires into extraordinary solutions. PARAVANT Architects is a dynamic design firm of international professionals located in Los Angeles, California. It turns the indoor setting into a haven of purified, revitalizing air, minimizing the potential presence of allergens and pollutants that could compromise both physical well-being and overall quality of life.

Passive Building Principles

Despite its incredible reputation as the gold standard for sustainable building design, the Passivhaus standard is still not fully understood by many within the profession. At a time when climate change is forcing people across the AEC industry to rethink the way in which they build, awareness of this standard is more critical than ever. Yet, strategies for increasing the sustainability of buildings have been around for decades.

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. The passive house concept delivers - the savings are real, there is no performance gap.

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. Learn how you can build comfortable, healthy, cost-efficient buildings for a more resilient world. The windows in a Passivhaus are high performance triple glazed with insulated window frames. These high performing windows ensure a warm, draught free building in winter and allow the building to benefit from winter solar heat gains. This is a myth – during the summer months it is common to open windows to purge any heat build up.

However, during the heating season, occupants often find they don’t need to open windows as the MVHR system provides ample fresh air. By following a holistic approach with these five principles through the design and construction on any project, owners, designers, and builders can be confident that they can achieve a truly high-performance building. Since Passive House projects are airtight, a ventilation system is needed to bring in fresh air and exhaust out built-up pollutants, odours, CO2, and moisture. During winter, this means dumping out warm air and bringing in cooler air that needs to be heated up again, which increases the heating energy. A Passive House ventilation system uses a heat recovery ventilator (HRV) to continuously remove stale or moist air and deliver fresh air. During this process, it extracts heat from the exhaust air and puts it into the incoming air without directly mixing the airstreams together.

In order to reduce this heat loss, insulation made of low-conductivity materials is installed within the wall and roof assemblies. The cost of building a passive house can vary widely depending on a number of factors, including the size and complexity of the building, local construction costs, and the specific technologies and materials used. However, passive houses generally cost more to build than conventional buildings, although the energy savings over time can offset this initial cost. Let’s take a look at some of the key trends and influencers in the housing sector’s move toward going green, such as passive house design, net-zero energy homes, green building materials, smart home technology and green roofs and vertical gardens.

Passive houses accomplish all this with green strategies, including super insulation, airtight construction and high-performance windows. Passive house design strategies can be used in any climate and in both new and existing buildings, including hospitals, schools and high-rises. The rectangular building is orientated to make use of passive solar gain and lined with insulation that performs nearly three times the minimum required by city code. It also makes use of eco-friendly materials and technologies including photovoltaic panels and an energy-recovery ventilator. With an airtight construction, it is important that a Passivhaus is consistently supplied with fresh air. This is performed by the mechanical ventilation and heat recovery (MVHR) system that supplies fresh air to the rooms virtually at room temperature by recovering heat from the exhaust air.

Although the initial construction costs of a passive house may be slightly higher, the substantial energy savings over time make it a wise investment. The reduced maintenance expenses, enhanced property value, and environmental benefits make passive houses a smart choice for those who prioritize long-term financial stability, comfort, and sustainability. They are not just houses; they are wise investments in a brighter, more sustainable future. Passive houses use up to 90% less energy for heating and cooling compared to conventional homes, resulting in significantly reduced energy bills and carbon footprints. The primary driver of these incredible energy savings in passive houses lies in their holistic design approach.

The know-how to design a passive house and how to improve an existing building step by step to come near to passive house standard - you'll find just here, from the pages of passipedia. Buildings of this kind often make use of triple glazing, solar heat gain and energy recovery ventilation systems. This means they can maintain an almost constant temperature, requiring little energy for heating and avoiding high energy bills. Next, it is critical to control solar radiation to achieve optimal passive house design.
