Energy efficiency advice

Removing and re-build is often the better alternative

Even an old totally renovated an old house remains. Worth the effort? Builders underestimate the effort and costs.

It seems the popular German citizens to be older houses to buy and then totally rebuild. In most cases, then the cost of rebuilding or redevelopment higher than a new building. Equally tempting is often the charm of an old building. It also seems to be tempting, that the entire development of the land and thus the house is available. The entire bureaucracy for permits connection falls away. The fact that in older houses, the whole connections need to be renewed, will be neglected. Even in these cases, some bureaucratic hurdles to overcome.

The entire building is to be reviewed. Both the quality as well as the droop. Those who have not experienced in retrospect often unpleasant and expensive surprises that the financial forecasts for the total rehabilitation exceed.

When Keller `s already starting to

Old cellar has its own smell, which is also through the rehabilitation often can not sell. The smell is even stronger, the older the house is. Rising damp and moisture, the lateral walls in the basement penetrating, have significantly damaged the building. The mortar is washed out, the stones are, if it is not just natural stones are disintegrated. The reclamation and rehabilitation of the basement walls are at considerable cost.

Also, the droop of the foundation, the basement walls and basement ceiling is not true anymore. In houses, the 100 years and older was often simply without foundation strip built. The first layer of bricks for the walls was simply on the ground. That was then bricked. A base plate, as is now customary, there was not. The bars for the basement ceiling have suffered by the moisture and must be repaired or completely be replaced.

Buildings on the planet

The buildings on the ground usually requires a reorganization. Furthermore, the architecture of older homes are not required of today’s energy efficiency. Unless the masonry is much greater than 50 cm. Very old buildings even have walls of 1.50 m thickness. These walls are made of broken stones. Breaking stones very difficult for a restoration. Wall breakthroughs can sometimes be a challenge. Another focus is the thermal insulation. With a subsequent thermal insulation can be a lot to be done wrong. Then from previously healthy homes, houses quickly sick. Due to the insulation, the walls no longer breathable. A vapor barrier with the foil on the inside of the exterior walls while preventing the ingress of moisture from inside the house, but has an unpleasant climate effect. A ventilation can help. These plants, however, are a significant intrusion into the buildings. Moreover, vulnerable and in the ongoing operation costs. In addition there is an annual cleaning and disinfection of the plant.

For a simple restoration of the experiences under the German Energy Agency (dena) costs an average of 60,000 euros. But the effort can be significantly higher.

Interior design of the houses is no longer

Today we are very different demands on the space allocation as at the time the houses were built. To the interior design in the existing floor plan to today’s needs, require a substantial outlay. The costs are so at 30,000 euros. The room height is the next problem. In the so-called noble houses, the rooms often 3 m and higher. From the energetic point of view, this room heights are no longer tenable. At the other extreme, room heights around 2 m, are in many settlement houses to be found. From energy, perhaps quite interesting, but for our current body sizes very Indoor Lighting.

Even houses that were younger than 50 years, have room layouts, which today no longer meet requirements.

Heating needs (almost) always be renewed

Old houses need new modern heating system. The usual hot water heaters (Konvektionsheizungen) with gas and Oil boilers require a substantial outlay. Ceiling and wall openings are expensive and sometimes cause static problems. The Konvektionsheizungen bring air circulation due to its high particulate matter pollution.

Less expensive and healthier you are already with their stone heaters radiant heat. This also slightly dry wet from old walls. The installation of these natural heating costs only half of a hot water heater. The cost for the operation of natural stone heaters are 50 percent lower compared to a gas or oil heating.

Sanitation no longer

The sanitary facilities meet the present needs and the health claims in any case. In existing buildings with a considerable effort to lay pipelines. The estimated costs can quickly order multiples are exceeded Sustainable Furniture. In old houses there is an increased need for rehabilitation during most of the work out.

Removing and re-build is usually the better alternative

The cost for a demolition of a house is generally around 10,000 euros. Then on a clean base or a base plate of the new building of the house. The dimensions of the new building can be chosen freely so far as there are no local restrictions for Solar Attic Fans. The outer dimensions of the old house but can also be adhered to, even the exterior view is 100 percent restored. The material can in most cases be chosen freely. We recommend a wooden stand construction with a cellulose insulation. When heating is also a new building in the already described on natural heating. This design is not a film barrier against condensation required. The exterior view can be selected. Plaster, brick or wood, everything is possible. Even historical views can be made.

The benefit costs are manageable, as no surprise as the remediation can occur.

The natural wood-based solid construction allows

This material combines the warmth of the wood materials and solid construction. It is a system for low-or passive construction. There is also a “fast” building

This material is massively built, without the drawbacks of conventional building materials, such as joints and cracks. The prefabricated wall elements ensure a rapid progress. Already on the second day the house is rain proof. The dry construction method allows for immediate interior. The static elements of the wall allows virtually limitless design possibilities. The local manufacturers can virtually all requests regarding the design of the building owners allow. Thus, manufacturers have no catalogs from which the customer’s house to look. Each house is individually designed and built. These prices are a turnkey at 1,000 euros per square meter of surface.

The great mass of evenly distributed wall panels inhibits the transmission of sound is fine. The wood has a high fire until the fire resistance class F90-B. The residents get homes with this material with ideal heat and cold protection. Houses of this type are characterized by a high eco-efficiency coupled with extreme durability and value.

Manufacture of wooden building material

For the production of certified food safe OSB (oriented beach board) panels are young pine logs used when browsing the German forests under the forest incurred. The source Green Home Products is a renewable resource and protects our environment. The highly resistant strain nuclei in a specific procedure in a long strip of wood split and under heavy pressure to major elements. How can whole wall elements are produced, which sometimes up to 5 tons can. These elements allow for a speedy construction.

This material offers a high insulation, high stability, ensuring high comfort and is the basis for coziness.

Construction of the house

The precast walls are positioned using a crane. For piping, cable channels, etc. can be in the construction of the walls corresponding channels in the walls are provided. Stemmarbeiten on the site are therefore not required. The interior walls can be made of the same material can be produced. The massive ceiling makes a high sound insulation and high durability even with Composters. Openings in the ceiling in every conceivable shape possible.

The facades of the house can be individually designed. Wood, brick or plastered walls are possible.

A good sense of living

The wood material is highly resilient. The wood material offers the advantages of the warm texture of wood. The moisture walls offer a comfortable room and good insulation, there are only low heating costs. The thermal Green Insulation in the summer is also protected by the wood guaranteed. The inhabitants of these houses enjoy this building material, thanks to a unique living environment. If you have rooms with a heated stone heating, can the effect of the feel-good atmosphere was increased.

The interior walls are all non-load-bearing walls. This is a free space possible. After years when the housing situation is different and needs have changed, is a reconstruction of the inner house without much effort.

The ideal smooth surfaces of the prefabricated walls allow an immediate wall design with wallpaper, Recycled Paint or whatever else the client wants. Hang pictures with a simple nail is due to the hardness of the material of the walls is not possible. It must be drilled and bolted.

Roof
Even for the roof panels can be used. The sun’s heat takes approximately 18 hours in order to penetrate the material. As long as the sun shines even in high summer with long days than not. In the night hours, the material can cool again.

We recommend, however, is a roofing material with a water-cooled photovoltaic plant and Water Conservation. In addition to electricity, the water still plenty of warm water.
