Applicable to all types of buildings including single-family homes and multifamily apartment buildings, these principles outline how to achieve a high standard of energy efficiency while also balancing comfort. The principles include thermal control, air control, radiation control, and moisture control. A passive house relies on a variety of techniques and technologies to minimize its energy consumption.
When and where was the concept developed?
"He reached out and said, 'Hey, I'm looking for X number of dollars for three months, and I'll give you 10% interest,'" she said. Doug Fox is a project manager at Fullcast, a Silicon Slopes-based end-to-end RevOps platform that allows companies to design, manage and track the performance of their revenue-generating teams. 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. The homes provided by ZenniHome to the Navajo Nation will address the critical housing need and stimulate economic development.

While fully converting a space to be more eco-friendly might seem out of reach (or out of pocket), sustainable design is a lot easier to pull off than you think. Appliances, building materials, heating systems, and a slew of other home components can all work toward achieving the goal of sustainability. Whether you’re buying a house and want to take note of the home’s ability to add green features or you’re building your own custom eco home, here are the features that experts suggest you consider for eco homes.
Is building a passive house more expensive than a standard house?
This type of home — built to a rigorous standard of construction to maximize energy efficiency — is widely embraced in Europe, though awareness is still growing in the United States. In this article, we’re going to explore what a passive house is, and speak with experts to understand the principles of passive house design and what it’s like to live in one. Passive house ventilation systems provide plentiful fresh filtered air free of dust and pollen, maximum energy efficiency through heat recovery system (HRV), and unlike other ventilation systems is is 100% fresh air (no air recirculation).
It is fundamental to the design that all the heat required can be transported by the normal low air volume required for ventilation. A maximum air temperature of 50 °C (122 °F) is applied, to prevent any possible smell of scorching from dust that escapes the filters in the system. Achieving the major decrease in heating energy consumption required by the standard involves a shift in approach to building design and construction.

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. And finally, the temperature should stay comfortable – as Passive Houses are geared towards regulating temperature, so they’re comfortable throughout the year. Similarly, there’s a maximum amount of energy Passive Houses can use to run your heating and domestic appliances. Companies that specialize in toxin-free cabinets include Puustelli Kitchens, Bertolini, KERF, PureKitchen, and more. Schneeberger recommends the Healthy Materials Lab at Parsons School of Design as a resource for finding sustainable materials and suppliers. “One home that’s not energy-efficient might require upgrading the windows, might require replacing an old pool pump with a variable speed pump, or replacing old appliances with newer, more efficient models.
Staffed mostly by Navajo workers, ZenniHome has a goal for its factory to become the highest-producing housing factory in the world. When expansion is completed by the end of 2025, the factory is expected to produce up to 25 homes a day. ZenniHome is currently already producing homes; earlier this month, nine units were delivered to Los Milics Vineyards near Tucson, Arizona. 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. If you were to keep the windows open all night, every night, this could affect the internal temperature and increase your energy use – but even then, it shouldn’t cause any issues. 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.
Mechanical ventilation
“With solar panels, homeowners can significantly reduce their dependence on traditional electricity sources, leading to substantial savings on their electric bills over time,” Lowe says. As part of a top-to-bottom renovation, consider installing a geothermal heating and cooling system to conserve energy. They work by tapping into stable temperatures a few feet below the earth’s surface to heat and cool a home. If you’re working with a designer to build a brand-new home, it’s imperative to employ passive design, which reduces a house’s ecological footprint by using the local climate and landscape to its advantage. One way to do that is taking note of the orientation of the house in relation to the sun. Passive buildings may not be a fixture of U.S. neighborhoods just yet, but minor upgrades like low-flush toilets and LED light bulbs are no longer enough for a home to be considered energy-efficient.
Windows and Doors
Because passive houses are so efficient, it’s easy to maintain a comfortable indoor temperature no matter the season. Savings on heating and cooling costs can be as high as 90% compared to conventionally built homes, since passive buildings use just 15 kWh of heating energy per 10 square feet per year. Yes, conceptually, an existing structure can be retrofitted to conform to passive house standards.
Since the process of building a home passive is carefully planned, there is almost no room for error. High-quality and durable materials are selected to create a passive home which leads to less maintenance and more bang for your buck. Not only is the internal temperature of a passive home very comfortable, but the air is much higher quality. The ventilation systems of these homes filter out allergens like pollen and dust more efficiently than a typical home, keeping the air fresh and free from any pollutants that could irritate those with allergies. “Passive construction focuses on heating and cooling, but as it has evolved, it’s become sort of a tool in the toolbox of people who are trying to achieve net-zero buildings,” explains Knezovich. A German physicist and a Swedish scientist later developed the metrics for what would become the gold standard of passive buildings; and the Passive House Institute, founded in 1996 in Darmstadt, Germany, remains the authority on passive construction principles.
The PHPP is an Excel based tool which allows the designer to simulate the behavior of the building both during ‘peak’ times, in winter and summer, and over an entire year. It is a flexible, easy to use model that allows for quick iterations and design alternate evaluations – taking into account different real world assumptions and possible future scenarios. The Passive House Standard criteria, which you can download from the PHI website, passivehouse.com, only takes up about 15 comfortably spaced pages. The power and reach of the Passive House Standard is it’s inherent simplicity and flexibility.
Then during construction, all components are documented in measured photographs to prove the project is built as designed. A passive house refers to a design and construction standard that aims to reduce heating and cooling requirements in homes. This way, conventional heating systems are no longer necessary which helps reduce wasteful fossil fuels used to constantly heat and cool a building. When it comes time to move into your next home, it benefits you—and the environment—to incorporate sustainable features. Eco homes make use of renewable resources, reduce energy consumption, and conserve natural resources, including water.
