Passipedia – the Passive House Resource
Passipedia constitutes a vast array of cutting edge, scientifically sound, Passive House relevant articles. On Passipedia, basic Passive House information and insights are available for all to see, whereas members of the International Passive House Association (iPHA) receive special access to the more in depth sections.

You want to get to know the Passive House concept in short time? As a start, we recommend the video “Passive House Explained in 90 Seconds” by Hans-Jörn Eich.
Passive House is a building standard that is truly energy efficient, comfortable and affordable at the same time. Passive House is not a brand name, but a tried and true construction concept that can be applied by anyone, anywhere.
Yet, a Passive House building is much more than “just” a low-energy building:
Passive House buildings allow for space heating and cooling related energy savings of up to 90% compared with typical building stock and over 75% compared to average new builds.
Passive House buildings use less than 1.5 l of oil or 1.5 m3 of gas to heat one square meter of living space for a year – substantially less than common “low-energy” buildings. Vast energy savings have been demonstrated in warm climates where typical buildings also require active cooling.
Passive House buildings make efficient use of the sun, internal heat sources and heat recovery, rendering conventional heating systems unnecessary throughout even the coldest of winters. During warmer months, Passive House buildings make use of passive cooling techniques such as strategic shading to keep them comfortably cool.
Passive House buildings are praised for the high level of comfort they offer. Internal surface temperatures vary little from indoor air temperatures, even in the face of extreme outdoor temperatures.
Appropriate windows and a building envelope consisting of a highly insulated roof and floor slab as well as highly insulated exterior walls keep the desired warmth in the house – or undesirable heat out.
A ventilation system imperceptibly supplies constant fresh air, making for superior air quality without unpleasant draughts. A highly efficient heat recovery unit allows for the heat contained in the exhaust air to be re-used.
Achieving Passive House levels of building performance requires careful detailing and equally careful implementation – selecting materials, manufacturing components, on site assembly. Whatever system is used to build them, they will almost certainly be increasingly produced under MMC and maybe Off-Site technologies.
To achieve this really requires engaging the whole team responsible for delivery on time and within budget. It requires a systematic, solution driven approach which brings discipline to the process, sharing information and communications. DfMA defines the process of taking these to the next level; a welcome change in the overall approach to project management and development.
All of this entails a shift in thinking to that already practiced by established ‘Off-Site’ MMC manufacturers. It can be quickly and easily incorporated into procedures and processes of building and development. Better still, you can make partnering arrangements with such manufacturers to gain all round benefits.
Greater collaborative ‘partnering’ between architects, builders and manufacturers will deliver these. The greater speed, accuracy and quality that can result from manufacturing components in a dry, controlled factory environment, together with the ability tom incorporate (yet to be invented) ‘Smart Ware’ gives home builders perhaps the only way of achieving this, together with improved on-site build quality AND controlling costs.
While resistance to the change to DfMA has been the norm, the wish of most UK Builders to deliver excellent customer service and top notch homes is now driving an increasing number to choose Off-Site for their developments. Also, as ‘OffSite Hub” note, architects and designers are moving toward DfMA, something we have been encouraging for over 20 years. The emergence of LA Developers will only speed up this process.
To assist them in doing so our “Easy Timber Frame “ now offers standard size modular timber frame elements for them to use as a design base, cutting down on technical design and engineering to produce win-win results. This virtually provides any housebuilder or architect with their own bespoke design factory facility.
