The Keys to Successful Passive House Implementation

Imagine buildings so well constructed they need virtually no heating or cooling and can cut normal utility bills by 50%–80%. Now imagine these buildings are also so airtight there is almost no air leakage or outside street noise, yet they provide healthy, fresh, filtered air throughout the day whether windows or doors are open or not. Moreover, these buildings are not dark boxes with tiny windows, but light, bright, spacious…


Let’s save fossil energy – Now!

#EfficiencyNOW shows ways towards independence from fossil fuels Darmstadt, Germany.  The call of the hour is to save fossil energy. To achieve this goal quickly, the Passive House Institute has started the #EfficiencyNOW campaign. The research institute explains how each one of us can contribute towards becoming more independent of fossil energy, and ultimately phasing it out altogether. On Passipedia, the Institute provides guidelines on how to go about this.…



PHN 2022 Passive House for All National Building Conference

Efficiency | Equity | Electrification | Embodied Carbon. We must transform our built environment with integrated solutions. We know the basic ingredients: efficiency, equity, electrification, and embodied carbon. We have the know-how today. So let’s dive into the synergies and the specifics. Let’s get aggressive, grab all of these tools, and take radical holistic action to build a healthy prosperous future for all people before it’s too late. If you…



Summer Comfort in Passive House Buildings: Guideline

With warming climate conditions the topic of resilience towards overheating is increasingly gaining importance, especially since high indoor temperatures are not only a matter of comfort, but are also highly related to health. Summer temperatures inside a building are majorly influenced by solar loads, internal heat sources and by the ventilation strategy. Design optimization suitable for the local climate conditions fundamentally influences (a) the achieved thermal summer comfort and (b)…


EpiPHany Corner | The Natural Order of Sustainability

When you are in the process of designing and constructing a new building, or planning for the remodeling or retrofitting an existing building, the Natural Order of Sustainability is: Passive First - Active Second - and Renewables Last. A “passive” solution delivers desired performance naturally, as a function of design, and continues to deliver that performance over time with little or no intervention other than basic maintenance. When you design…



Central Coast Climate Collaborative (4C)

Passive House California is pleased to announce that we have joined the Central Coast Climate Collaborative (4C) in support of our aligned efforts to “Advance Equitable Climate Solutions”. 4C’s focus is on California’s central coast, where PHCA is engaged with several jurisdictions, and other entities related to environmentally responsible design and building. We are looking forward to positive synergy from our combined efforts. If you would like to know more…


The Ice Box Challenge Sydney has officially begun!

A big congratulations to APHA for all their hard work!   One box was designed and built to typical Australian building standards and the other to the Passive House Standard, both containing an equal amount of ice.   This edition of the Ice Box Challenge includes sensors and cameras built into the boxes, providing regular updates on the internal humidity, volume, temperature and more.   Find out more Previous Ice-Box…


EpiPHany Corner | A High-Performance Enclosure: The #1 Priority for Resiliency

Resiliency is the “ability to withstand and recover from difficult life events.” In the case of buildings, difficult life events include extreme heat or cold, wildfires, airborne pollutants (including smoke), and power outages. The #1 priority for achieving resiliency is a high-performance enclosure (envelope) The #1 priority for attaining a high-performance enclosure is air sealing Employing Passive House protocols is the #1 way of delivering an airtight enclosure The high-performing…


Passive Housed Durability – Condensation

When we think of Passive Houses, the first things that usually come to mind are airtightness (0.6 ACH50), above-average insulation levels, and whole-house ventilation. However, there are some additional subtleties to Passive House certification that are often overlooked. One of those subtleties that can be problematic is the Minimum Temperature Factor. This is a unitless value that indicates the likelihood that a location in the building has the potential to…
