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.

Many existing office and administrative buildings are not air conditioned. This makes it all the more difficult to concentrate on work with increasing temperatures. Scientists have therefore analysed which measures can be used to improve user satisfaction. The BINE-Projektinfo brochure "Keeping a cool head in the summer heat" (04/2016) presents investigations and models to assess the thermal comfort.

A unique research and innovation platform has opened its doors: on 23 May 2016, the modular experimental building NEST was inaugurated on the Dübendorf campus of the two research institutes Empa and Eawag. Its official goal: to accelerate the innovation process in the building and energy sector by enabling research, industry and the public sector to co-develop sustainable technologies, materials and systems and test them under real-world conditions.
A residential building, office block and experimental laboratory all rolled into one: NEST is a “living lab” in the truest sense of the word. Those who live in...23.05.2016 | Read more
Until now most existing buildings have been pure energy consumers: the electricity comes from the power grid and the heat from a boiler, heat pump or heating network. However, buildings have a range of possibilities available to them to generate the energy they need by themselves.
The BINE Themen-info brochure “Net Zero Energy and Net Energy Plus Buildings” presents the various concepts. One focus is on how the energy balance for these...18.03.2016 | Read more
Noise is disturbing and can be harmful to health. Empa researchers have now succeeded in simulating road noise by means of «auralisation». The aim is to make noise audible along traffic routes that are merely in the planning stage – and thus include countermeasures at the same time.

The restoration glasses TIKANA®, RESTOVER® and GOETHEGLAS will be focused by the technology group SCHOTT at its premiere at Monumento, the trade fair on monument preservation, to be held in Salzburg, Austria, from January 28 - 30, 2016 (Hall 10, Booth 124). With these types of products that are produced using authentic techniques, architects cannot only restore original historical monuments from different eras. These glasses can also be processed in many ways and thus help to meet contemporary constructional requirements and capabilities –from UV protection to thermal insulation.
The restoration of old monuments is a delicate task for a number of reasons. On the one hand, it is of high importance for the monument preservation...26.01.2016 | Read more

95% of the geothermal water resources in Germany are situated in crystalline rock. Existing drilling methods, however, are only able to advance slowly though this hard rock and the drill bits wear out quickly. The BINE Projektinfo brochure “Electric impulses fragment hard rock” (13/2015) presents an alternative drilling procedure. Here, a high-voltage impulse fragments the rock. This method causes little wear to the drill bits and enables up to 30% lower drilling costs.

Working in conjunction with Giessen’s municipal utility company, Giessen and Marburg University Hospital has become the first German hospital to integrate its energy centre into an urban district heating network. The core of the combined cooling, heating and power plant is provided by four cogeneration modules that produce electricity and heat. The BINE Projektinfo brochure 12/2015 “Energy centre supplies Giessen University Hospital” describes the initial operating experiences.
