Achieving Maximum Energy Efficiency with Passive House Systems
Redefining Comfort in Buildings
PASSIVE HOUSE
Passive House is a relatively new standard for energy efficiency in buildings that reduces a building’s environmental footprint by achieving ultra-low energy consumption required to maintain a constant indoor temperature regardless of outside weather conditions.
What’s more, this means that a building stays warm and cozy in the winter with minimal use of energy sources, while staying cool and comfortable in the summer without the need for conventional air conditioning.
Furthermore – Buildings designed to the Passive House standard can save up to 90% of energy compared to traditional construction methods, making them an excellent long-term investment.
Passive House design is based on five principles: airtightness, ventilation, insulation, HVAC and electrical loads.
OUR PASSIVE HOUSE SYSTEM SOLUTIONS
Eco Passive House windows and doors are designed to provide excellent insulation, airtightness and adequate solar gain. Helping to maintain a constant temperature within the space and reducing the need for external heating or cooling.
In addition to reducing energy consumption and heating and cooling bills, they improve indoor air quality and create a more comfortable and sustainable living environment.
HOW PASSIVE HOUSE WINDOWS AND DOORS OUTPERFORM CONVENTIONAL WINDOWS AND DOORS
Insulation: Eco Passive House windows and doors use high-quality insulation materials, including insulated triple or quadruple-pane glazings with Argon or Krypton-filled cavities. These features effectively reduce heat loss and prevent cold air from entering the home.
Airtightness: Passive House windows and doors feature three separate gaskets to maximize airtightness, blocking drafts and air leakage. This design helps maintain a constant indoor temperature and improves air quality by keeping pollutants and pollen outside.
Solar Gain: Eco windows and doors are engineered to balance solar heat gain through insulated glazing. For unobstructed south-facing windows, the solar heat gain typically exceeds heat loss, even in mid-winter. This balance reduces the need for external heating, as natural sunlight warms the interior.
Ventilation: Eco Windows and doors can also support micro-ventilation through built-in micro-vents with filters. This allows for natural ventilation without opening the window or door, preserving insulation. This feature is particularly beneficial for maintaining a healthy indoor environment, especially for those with respiratory issues.
how quadruple pane windows save energy?
Quadruple-pane windows, also called quad-glazed or four-pane windows, save more energy than triple-pane windows due to the extra pane of glass.
With four panes of glass, three separate chambers are created, each filled with Argon or Krypton gas. The additional gas-filled chamber boosts insulation levels and further reduces heat loss between the interior and exterior of the building.
HOW TO OPTIMIZE ENERGY EFFICIENCY WITH PASSIVE HOUSE WINDOWS AND DOORS ?
Optimization of energy efficiency with passive house windows and doors in home environment is an essential factor to reduce energy costs. Here are some tips on how to achieve it:
1. Install energy efficient windows and doors with multiple panes of glass, properly optimized for your climate zone and location.
2. Choose the right window and door system. The material used for window and door frames has a significant impact on energy efficiency and should be optimized along with glass selection.
3. Use window coverings. Install blinds, shades, or curtains to block solar heat in the summer and retain heat in the winter.
4. Professional installation. Hire professionals who use high-performance materials and methods to eliminate air and water leaks and ensure smooth, long-lasting operation of equipment.
5. Maintenance. Be sure to periodically check the operation of each unit, air tightness and condition of seals. Refer to the Maintenance Guide for more information.
By following these tips, you can optimize and improve your home’s energy efficiency and reduce your overall energy costs.
Passive House Systems FAQ:
A “Passive House” window is not just a marketing term; it refers to a window that meets the rigorous performance standards set by the Passive House Institute (PHI) or Passive House Institute US (PHIUS). While many high-quality windows use triple-pane glass, a certified Passive House window must also have an exceptionally well-insulated frame and a “thermal bridge-free” design. The key difference is the holistic performance: the entire window assembly – glass, spacers, and frame – is tested and proven to have an extremely low U-value (a measure of heat loss) and superior airtightness. This ensures it performs as a net energy gainer, contributing to the building’s heating rather than detracting from it.
U-value measures how well a window prevents heat from escaping a building. The lower the U-value, the better the window’s insulating performance. For comparison, a standard double-pane window might have a U-value of 0.48 or higher. To meet the stringent Passive House standard, a window’s installed U-value must typically be ≤ 0.15 BTU/h·ft²·°F (or 0.8 W/m²K in metric). Our Passive House window and door systems, are specifically engineered to meet or exceed these requirements, achieving some of the lowest U-values available on the market today.
While the energy savings are significant, the day-to-day living benefits are just as important. These include:
- Unmatched Thermal Comfort: The interior surface of the glass stays close to room temperature, even on the coldest days. This eliminates cold drafts and radiant cold spots, allowing you to comfortably use all the space right up to the window.
- Superior Acoustic Performance: The combination of triple-pane glazing and exceptionally airtight seals dramatically reduces outside noise, creating a much quieter and more peaceful indoor environment.
- Improved Air Quality & Health: The airtight construction prevents drafts, dust, pollen, and other pollutants from entering your home, contributing to a healthier indoor environment.
- Condensation Resistance: Because the interior pane of glass remains warm, condensation and potential mold growth are eliminated.
Absolutely not. While our windows are designed to meet the strict requirements of a certified Passive House project, they are an excellent choice for any new build or renovation where superior energy performance, comfort, and durability are a priority. Many of our clients install them in “high-performance homes,” “deep energy retrofits,” or simply in projects where they want to create the most comfortable and resilient building possible, regardless of official certification. They are the ultimate upgrade for any project aiming for net-zero or near-net-zero energy consumption.
