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.

Wireless Sensors and Flying Robots: A Way to Monitor Deteriorating Bridges

As a recent report from the Obama administration warns that one in four bridges in the United States needs significant repair or cannot handle automobile traffic, Tufts University engineers are employing wireless sensors and flying robots that could have the potential to help authorities monitor the condition of bridges in real time.

Today, bridges are inspected visually by teams of engineers who dangle beneath the bridge on cables or look up at the bridge from an elevated work platform. It...
