There are many reasons to build a passive house. The most important are related to the cost advantages you enjoy by building a passive house. The architecture of a passive house is designed so that the basic needs of the home owner, with respect to energy supply, are autonomously controlled. As the term "passive" implies, regulating the energy balance requires no action on your part. This capability stems from the architecture of the house. Roughly 8,000 people in Germany have meanwhile taken advantage of this architecture to build a passive house. But how does a passive house function and what is the respective architecture basically made of? The architecture is typically designed so that the outer shell of the passive house is insulated to keep the heat from escaping outside.
When building a passive house, a ventilation system acts to additional recover 80 percent of the heat. The roof of a passive house is designed to capture additional heat and store it until the room temperature sinks enough so that it must be released. Related studies have shown that a passive house constantly maintains an indoor temperature of more than 20°C at an outside temperature of -14°C. A passive house provides the freedom to individualize the architecture. The owner can decide whether to build the house out of concrete/brick, wood or a combination. The architecture always depends on the architect and the individual plan. However, there are several factors to consider when building a passive house.
Passive houses exhibit specific characteristics that are tied to the architecture. The external building components must be extremely well insulated in addition to carefully constructing the corners, edges, joints and other cross sections. This would otherwise lead to excessive heat loss and failure of the architecture to fulfill the desired requirements. By taking these factors into account and using the right approach to building a passive house, one can expect a minimal heat loss of only .15 watts per square meter of external surface area. If you are building a house, the architecture should be designed to maximize the energy gain through the solar cells. For this reason, the solar cells on the roof of the passive house must have a southerly orientation.
To build a passive house, it should be designed such that the respective solar collectors and heat pumps supply power to the hot water system. When building a passive house and using the appropriate architecture, you can expect to significantly lower your operating costs.
The architecture is what makes it possible for you to build a passive house and to have a complete energy system that runs on its own. While more and more people are dreaming of building a house, it always involves high costs. With the right architecture, you can build a passive house assuming that you will benefit from significantly lower monthly operating costs. This approach allows you to build to a house that runs completely on its own thanks to the corresponding high-quality architecture . Because the architecture is so well thought-out, you can build this house under the assumption that the heating balance will regulate itself. For this reason, you can assume that building a house is a worthwhile effort.
Here you can discover new and innovative developments from the world of building design and construction.
innovations-report offers reports and articles on a variety of topics such as building optimization, modern construction materials, energy-efficient construction, natural insulation materials and passive buildings.
Using a system developed by Fraunhofer FIT, architects, developers or their clients can view a 3D model of a building in its intended shape, precisely where the building is to be constructed. This will give them a much clearer, realistic impression of the design. We will demonstrate the system at BAU 2015 held in Munich from January 19 to 24, 2015.

When it is very warm outside, the air conditioning system takes care of a consistently cool room climate inside the house. The water paraffin mixture CryoSol®Plus could make the purchasing of an air conditioning system for office buildings superfluous in the future and at the same time considerably unburden the power grids. Fraunhofer UMSICHT is researching areas of use for phase change slurries (PCS).
Cryosol®Plus looks like milk. But don't even think about drinking it. While the composition made of paraffins and water is non-poisonous, it still isn't all...03.12.2014 | Read more
Coming home from work one day, you’re taken aback to find your apartment building encased in scaffolding. And then it hits you that the agency that manages the property did announce that your building is going to be renovated with the promise that a new façade and new windows will mean paying less for utilities.
You can now look forward to months of noise pollution and to artificial darkness caused by the scaffolding wrap and there are bound to be interruptions and...10.11.2014 | Read more

In various industries such as automotive industry, aircraft or steel construction failures in the final product can quickly lead to malfunction and, as a result, can massively compromise the operational reliability. Thus, nondestructive testing methods will play a key role in the quality assurance because they allow to inspect components and parts without destroying them.
From 10 to 12 March 2015, at the JEC Europe in Paris, engineers of Fraunhofer IZFP in Saarbrücken will introduce a novel procedure which enables noncontact and...
