Passive House Design: What All Homeowners Should Know
Table Of Content
And, as they become more commonplace, Passive Houses are getting cheaper to build. One of the ways to achieve ‘superinsulation’ is to avoid what’s called ‘thermal bridging’ – using a material that’s less well-insulated than the rest of the house exterior. This could be the frame of a window, for example, which conducts heat more than the other materials around it. With all of these benefits, a passive house is bound to attract a multitude of tenants. There are many people out there who aren’t in the position to buy or build a passive home on their own but want to do their part to live sustainably and reap all of its benefits.

Air Control
These may include high levels of insulation, air-tight construction, triple-glazed windows, and heat recovery ventilation systems. In a passive house, the building itself and its mechanical systems are treated as one single, overall system. To help maintain the necessary balance in the system between hot and cold, and between stale air and fresh, architects and engineers use a sophisticated software program to design passive homes and determine their projected energy usage.
Are passive houses suitable for all climates?
The two standards ("passive house" and PHIUS+) are distinct and target different performance metrics and use different energy modeling software and protocols. Products that had been developed according to the passifhaus standard were further commercialized during and following the European Union sponsored CEPHEUS project, which proved the concept in five European countries in the winter of 2000–2001. After years of careful planning (during the pandemic, no less), Hotel Marcel New Haven opened in May of 2022 as the country’s first Passive House-certified hotel. For this distinction, the 165-room property had to meet rigorous standards by demonstrating high energy efficency, resiliency, and exemplary comfort year round. The choice of building materials can play a crucial role in a home’s eventual sustainability.
Comfortable
Thermal control involves keeping the inside of a home warm when it is cold outside and cool when it is hot outside. One way of achieving this is by having a high-performance enclosure, which includes continuous insulation throughout the entire building to reduce heating and cooling needs. Phius trains and certifies professionals, maintains the Phius climate-specific passive building standard, certifies and quality assures passive buildings, certifies high-performance building products and conducts research to advance high-performance building. ROCKWOOL’s non-combustible stone wool insulation is ideal for reaching passive house standards because it fits easily into the building and stays in shape over time, lets vapour pass through, is long-lasting and fire-safe.
Windows & Glazing
PHLA+ is a project designed by PARAVANT Architects strategically planned to showcase the international passive house construction standard. This includes demonstrating the back-end technologies, comfort, indoor air quality, high energy efficiency, and sustainable building practices. This passive technique is not about relying on solar or wind power; instead, these homes achieve near-zero energy consumption by being incredibly airtight and insulated. The benefits of living in a passive house include lower energy bills, improved indoor air quality, and a reduced environmental impact. Additionally, passive houses tend to be more comfortable and quieter than conventional buildings.
Design may be assisted by use of the 'Passivhaus Planning Package' (PHPP),[59] which uses specifically designed computer simulations. Homes that produce as much energy as they use over the course of a year are considered net-zero energy homes. These homes utilize renewable energy sources like solar panels and wind turbines to generate electricity. 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.
Passive house design principles are gaining traction worldwide as an effective way to minimize energy consumption in buildings. Typical homes allow unwanted flows of energy between the exterior and interior. An airtight building needs proper ventilation to ensure air quality and protect against moisture damage. Passive homes use a heat recovery ventilator (HRV) to continuously circulate fresh, filtered air while capturing and retaining at least 75% of heat from the exhaust air. Passive houses are designed to avoid leakages in the building envelope, thus boosting energy efficiency while preventing draughts and moisture damage.

Passive home designers balance heat and energy from the sun by determining when it is needed (called daylighting) and using shading strategies when it is not needed. The Passive House Standard is rigorous and focused – and includes specific certification targets or criteria, with metrics that include comfort, health and energy – to deliver high-quality. These are not relative targets, set to a baseline that can be gamed, but hard targets that leave you knowing where you stand. Today, the targets include increasing levels of renewable energy integration, and ever greater efficiencies, supporting electrification and a resilient green grid. Passive House is not only one of the world’s leading energy efficiency standards but also a construction concept made to build comfortable, environmentally friendly and affordable homes and buildings.
Principles of Passive Net Zero Energy Building
PHLA+ is located on a duplex lot, infill site, and is comprised of 1,750 sq.ft. Large windows provide sufficient natural light and a connection between indoor and outdoor living even with this home’s limited views. Exterior fully automated venetian blinds reduce heat gain, glare, effectively keeping the house cooler and comfortable. The entire building envelope including airtightness, windows, exterior wall systems and insulation are combined to produce significant energy cost savings not possible with conventional building practices.
The following pages provide examples and useful recommendations on Energy savings – if you do it, do it right! Passive houses can use up to 90 percent less energy than a conventional house. Thoughtful, thermal-bridge-free enclosure design eliminates "cold corners," minimizes risk of mold growth on the interior, and improves comfort. Olivia Young is a writer, fact checker, and green living expert passionate about tiny living, climate advocacy, and all things nature. PHIUS was originally an affiliate and approved trainer and certifier for the Passive House Institute. In 2011, PHI cancelled its contract with PHIUS for misconduct.[45] PHIUS disputed the claims by PHI and continued working to launch an independent building performance program.
Passivhaus standards are most effective in new builds, rather than in renovations. So, in order to enjoy all of those energy-saving tweaks to the maximum, you’d need to be in a position to build a new home from scratch. As this graphic shows, a Passive House needs just 15 kWh of heating energy per square metre net floor surface per year (15 kWh/m2a). Over the course of 20 years, homeowners can save between $10,000 and $30,000 by putting solar panels on their roofs, says Rodriguez. She reasons money isn’t the only thing being saved, pointing to a UC Berkeley study that found a residential solar system can power a home with 80 percent lower carbon emissions than that of fossil fuels.
Stay informed on the Passive House building standard, project developments, upcoming events and courses. Led by the Phius Technical Committee, our team conducts cutting-edge research to continue the advancement of Phius and passive building. If you’re an architect, engineer or building consultant, empower the building fabric, leverage the enclosure and make the most sustainable buildings possible with Passive House as your platform. The Certified Passive House Designer training is accessible, flexible and affordable. However, unless you are a very experienced practitioner with many certified buildings under your belt, you simply don’t know what you don’t know.
Passive House buildings not only save money over the long term, but are surprisingly affordable to begin with. The investment in higher quality building components required by the Passive House Standard is mitigated by the elimination of expensive heating and cooling systems. Additional financial support increasingly available in many countries makes building a Passive House all the more feasible.
Solar access have been a very important factor in any design of a passive house as it allows the structure to use the solar energy to heat and light the space naturally, and to replace electrical water heaters with solar energy-based water heaters. Solar powered exterior circulation, security, and landscape lighting – with photovoltaic cells on each fixture or connecting to a central Solar panel system, are available for gardens and outdoor needs. Low voltage systems can be used for more controlled or independent illumination, while still using less electricity than conventional fixtures and lamps. Timers, motion detection and natural light operation sensors reduce energy consumption, and light pollution even further for a passivhaus setting. Plus, you’ll make savings in the construction process – for instance, by not needing to spend money on a central heating system.
Phius sets the standard for passive house in North America and has certified 3,000+ professionals. An innovative way to design homes, a Passive House – or Passivhaus, as they’re known in mainland Europe – makes use of the ‘passive’ influences on a building. Using designs that draw on sunshine, shade and ventilation, they maintain a comfortable temperature without needing to use as much energy as a traditional home – whether that’s heating in the winter, or air conditioning in the summer. Although building or redesigning an existing property to passive standards can take time, it’s a worthy investment for the benefits of the earth and to its future residents.
