C. After spending more than a decade as an architectural employee in the italian market of high-performance residential apartments, i now run a company that deals with advanced building sciences and passive house design. We are based in denver, colorado, and northern italy, where we work in an international market with builders, experts, and manufacturers of high-performance developments and products. The term “passive” is now applied almost as often as the word “green”. And what does it mean? And when does a comprehensive adjective differ from the measurable standards of a capitalized passive house? I mentioned earlier that the truth of green building lies in such details. Here's how to navigate vocabulary and implied meanings in the light of passive design. “A similar structure was designed in the style of passive solar principles " suggests that the orientation of the self and the location of the windows were used to order heat using native natural light. Perhaps even considered shading for hot summers. These are the initial as well as the most fundamental steps to reduce energy consumption at home. "The timber cottage was designed to meet the requirements of a passive house" means that the architect and builder are always willing to follow a set of measurable building standards that promote low energy consumption. “The log cottage is an official passive house " means that the bonus to everything that the structure is designed and built in compliance with the standard of a passive house, it has successfully passed the certification procedure. Certification is managed by many companies in different countries. The original was the passivhaus institute in belgium and france, which is still widely popular around the world. This bike has many partners of companies in any country in europe. The united states ' largest certifying passive house institute, which recently parted ways with the german organization to separately review north america according to regional climate features. So, what is the passive house standard? Despite the impression that trigger is able to make, passive cottages are what you need, by no means lazy. A house designed to use the solar heat flowing through the window, actively saves energy. Having taken the next step in advance and made the transition to the standard of passive housing construction, the house is designed and manufactured in such a way as to function properly regardless of the time of year, in order to maintain a cozy and healthy living environment in the house without consuming extra energy. A house built according to the standards of a passive dacha is a result that remains comfortable for the entire duration of the season without the participation of an active heating or cooling system. It all depends on your state and local standards the project should meet the maximum annual energy consumption limits that can be considered. Historically, and still in the uk, this was 15 kilowatts of time, per free meter per year. Since then, the us standard has refined the specified limit in an effort to address specific climate zones. In no case are we talking about 60-70 percent of the value, often even more, passive house windows in saving energy in front of conventional buildings. How is a landing page capable of being possible It is not terrible, in a passive house all the energy that would be useful for heating or cooling the house is not needed for a long time. We, architects of passive houses, start with a compact building form. You will find that most of the passive houses are actually box shaped. Then we can add visual intrigue by using unconstrained open rooms and covered spaces to break up the facade. But this compact box core plays a huge role and is the basis of any concept of efficiency. In winter, the passive solar design takes as much heat as possible from the sun's rays. This implies the orientation of the house in the specialty to the solar door and getting so that the low angle of the winter sun can penetrate even further inside the room. We place to this heat, which is created in the home only from the presence of people. We use mechanical ventilation, in order not to disturb the air with fresh air, heating the incoming air with exhaust air. Here we use dehumidifiers to maintain a healthy level of moisture and prevent mold. In the heat, we embody the shading effects and excellent angle of the summer sun. So we are able to prevent the sun from passing through the windows, floors or walls, helping not to lose them cool. In the end, our company is vigilant to ensure that the heat does not go through the building skin, designing a sealed and insulated shell of the building. The current photo shows the insulation made of stone wool. And not as on leed, the passive log cabin standard does not wait for the availability of natural or recycled materials. Certification is based solely on energy performance. Not only do the walls, slabs, and roof need to be properly insulated, as well as all the seams. High-quality windows are just about the most significant upfront cost in a passive home, but they make a solid contribution to energy savings. We can insulate like crazy, but if we embody windows with a low level, all the heat will escape through the glass. The building's skin-like shell is only as strong as its weakest point. I often describe the shell of a building as an inflated balloon. One hole in the airship, and the exhausting air will escape. It does not matter how strong the rest of the balloon is. Therefore, our employees not only want to get a consistently insulated shell of the building, but also are always ready not to get under various air leaks when hot air can leave in winter or enter in summer. One of the sources that the passive house standard checks for air leaks is the difficult test of the blower door, which closes the entire house and pumps the atmosphere inside. The sensor shown here then measures the air flow relative to the volume of the house. Such tests, in parallel with energy modeling, measure whether a property is built according to the standards of a passive house. The issue of whether a passive house will become valid without official certification is a subject of constant discussion. Some pros say that certification is an additional and unnecessary expense. Others suggest that this adds transparency and control to the entire process, making everyone accountable to the goals. Some homeowners find it a necessary part of raising the market price of a particular home. Others don't see the point here, of course, if the firms don't want to sell. In general, it is very important that users trust their project team, as well as understand the whole situation. The word “passive” is not considered a brand like leed, so make sure that you know the context in which it is used in the catalog.
