What is a passive house and how is the architecture designed?

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.

The passive house runs on its own

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.

The characteristics of a passive house thanks to its architecture

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.

Lower the 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.

Bridges equipped with dampers against earthquakes

Researchers at the Universitat Jaume I of Castelló and at the University of California have devised a system to reduce the damage caused by earthquakes in bridges. Installed between the piers of a bridge and their respective foundations, it is a flexible device that helps to mitigate the effects produced by the movement of the Earth’s surface, working in a similar way to the shock absorbers in cars. The study has been published in the journal Earthquake Engineering and Structural Dynamics. < 08.09.2005 | nachricht Read more

Combining technologies leads to safer, more efficient crane

EUREKA project E! 2797 FACTORY MSETC (Mobile Self-Erecting Tower Crane) has successfully combined the technologies of mobile and self-erecting cranes to create a single crane that can do the work of five. The new crane features an anti-sway device which makes it safer as well as more efficient. The Belgian lead partner, Arcomet NV, has developed self-erecting tower cranes for the building industry for many years. “These cranes were mounted and remained in a fixed position on 03.03.2005 | nachricht Read more

Sprinklers shown effective in slowing dorm fires

An automatic sprinkler system significantly increases a person’s chances of surviving a dormitory fire, according to a report issued recently by the National Institute of Standards and Technology (NIST). Three NIST experiments,* supported by a U.S. Fire Administration (USFA) initiative for fire safety in college housing, compared the hazards of fires in smoke detector-equipped dormitories with and without fire sprinklers in the room of fire origin.

Decorators Uncover Rare Architectural Find

An exciting find has been made by decorators working at A-listed Lilybank House, which belongs to the University of Glasgow. Hidden beneath layers of paint the decorators discovered colourful original stencilling work which experts are sure date back to 1863, when this addition to the house was designed by Alexander ‘Greek’ Thomson.

Im Focus: A step towards controlling spin-dependent petahertz electronics by material defects

The operational speed of semiconductors in various electronic and optoelectronic devices is limited to several gigahertz (a billion oscillations per second). This constrains the upper limit of the operational speed of computing. Now researchers from the Max Planck Institute for the Structure and Dynamics of Matter in Hamburg, Germany, and the Indian Institute of Technology in Bombay have explained how these processes can be sped up through the use of light waves and defected solid materials.

Light waves perform several hundred trillion oscillations per second. Hence, it is natural to envision employing light oscillations to drive the electronic...

Im Focus: Freiburg researcher investigate the origins of surface texture

Most natural and artificial surfaces are rough: metals and even glasses that appear smooth to the naked eye can look like jagged mountain ranges under the microscope. There is currently no uniform theory about the origin of this roughness despite it being observed on all scales, from the atomic to the tectonic. Scientists suspect that the rough surface is formed by irreversible plastic deformation that occurs in many processes of mechanical machining of components such as milling.

Prof. Dr. Lars Pastewka from the Simulation group at the Department of Microsystems Engineering at the University of Freiburg and his team have simulated such...

Im Focus: Making the internet more energy efficient through systemic optimization

Researchers at Chalmers University of Technology, Sweden, recently completed a 5-year research project looking at how to make fibre optic communications systems more energy efficient. Among their proposals are smart, error-correcting data chip circuits, which they refined to be 10 times less energy consumptive. The project has yielded several scientific articles, in publications including Nature Communications.

Streaming films and music, scrolling through social media, and using cloud-based storage services are everyday activities now.

Im Focus: New synthesis methods enhance 3D chemical space for drug discovery

After helping develop a new approach for organic synthesis -- carbon-hydrogen functionalization -- scientists at Emory University are now showing how this approach may apply to drug discovery. Nature Catalysis published their most recent work -- a streamlined process for making a three-dimensional scaffold of keen interest to the pharmaceutical industry.

"Our tools open up whole new chemical space for potential drug targets," says Huw Davies, Emory professor of organic chemistry and senior author of the paper.
