Nemetschek puts up for discussion: shopping is really only ‘ procurement? Still, some construction companies to see a pure instrument for material procurement. Some understand it but also as a task to reduce costs – cheaper, better and faster ready to make. Purchasing and suppliers of a company are crucial levers of corporate development. Especially because increasing shares of the material cost in all construction areas allow large savings when shopping. Who manages to use them, win a significant competitive advantage over its competitors. Optimization of the value chain the challenges are increasing constantly.

Globalization, technological innovation and stronger cost pressures require new approaches. Angus King may not feel the same. Strategic thinking must involve from the outset the shopping in the construction company. Additional design tasks are added to the classic shopping tasks. Specifically the aim is value-oriented to make the purchasing network and the customer-supplier relations. The guiding principle of value Sourcing’ summarizes all concepts and instruments of modern shopping management that can lead to a sustainable increase of the company’s success. It is important to note value orientation needs another shopping program some factors: the derivation of a changed shopping programme shopping supposed to use its full potential to increase in value is essential. Such a programme includes the collection and assessment of the initial situation. The basis for differentiated and realistic goals of purchasing is created with the positioning of the current purchasing power.

Target shopping success and not saving: The purchase program has the ambitious objective of meet, between short-term cost-cutting measures and medium – / long-term value enhancement programs to balance. As a target to the control of procurement activities is therefore to replace savings success factors. The success of shopping to be defined is the achievement of objectives set, consisting of cost, quality, time and Innovation objectives – to derive from the corporate objectives. The one-sided orientation on savings is thus avoided.

The stricter EnEV 2009 places high demands on the building envelope. A 30 percent higher thermal insulation is intended as essential insulation of the roof of any new building more. (tdx) Target the energy saving regulation is generally the reduction of energy needs for heating and hot water throughout the building to an absolute minimum. Gradually, the regulation closer to this goal. Last October the stricter EnEV is already in force in 2009. She has aimed to reduce energy consumption by a further 30 percent compared to the previous regulation.

Concrete result increased requirements to the building envelope, and thus also on the roof. The insulation of a roof at a new building must pay 30 percent more heat protection in the future than previously without a proper insulation is not achieving this goal. Whether on -, intermediate – or under Rafter insulation, especially the quality of the material used is important. Mineral insulating materials, such as glass or rock wool, have significantly higher As plant insulation on insulation values and have proven themselves in practice. Also applies when choosing the right insulation material: the lower the thermal conductivity the higher thermal insulation. The generation 032 of ISOVER, for example, boasts a thermal conductivity only 0,32 W / mK and is thus highly insulating. Dach.de experts recommend in any case to a material combination which guarantees the roof a U-value less than 0.22 W / mK. The insulation can show their full effect, must be also the roof skin in perfect condition.

Because as soon as moisture can penetrate, there is a risk that the insulation becomes ineffective. This also applies to connections on the wall, floor and ceiling: here should be worked using special adhesive tape and check the air-tightness of the structure. An insulation of a roof is not only in terms of the thermal insulation in the winter of particular importance: in the summer, the insulation plays an equally important role. Much about air conditioners Energy lost. Energy can be saved with proper insulation. Because the insulation protects not only cooling off, but also heat. This prevents the summer that the attic, may excessively heat up and the air conditioner can safely be dispensed with. These ensure the minimization of the cooling energy is prescribed in the new EnEV 2009, thus it meets several with roof insulation at once. An insulation of a roof is essential not only for the new building: in a historic building must be retrofitted. By the end of 2011, the attic must receive a thermal insulation as the topmost accessible floor. For this, special insulation boards can be placed, can reduce oil consumption per square meter by 90 percent. A roof insulation effectively helps to save energy, thus to sustainably reduce the CO2 emissions and the environment protected. View website helps readers to explore varied viewpoints. The own purse and the living environment benefit also, in short: the quality of life under the roof rises.

Insulation thickness of 300 mm or more were hitherto typical for passive houses. But thanks to which can be reached with the vakuVIP panels of vacuum isothermal GmbH this standard as at 30 mm insulation thickness. Others who may share this opinion include Rogers Holdings. The advantages are clear: an extremely high insulation value in comparatively reduced insulation thickness allows a usual sleek facade, roof, or floor construction and still allows a passive house suitable for insulating value. The possibilities are wide ranging. Everywhere, where too little space is for conventional insulation materials can be used vacuum insulation space-saving and highly effective. Passive house typical insulation values are now also available in the remediation. New opportunities also arise in steel -, aluminium – and wood-aluminium cladding. The required panels are made suitable for the facade modules and achieve always einenbesseren insulation value than the used glass discs with same or thinner panel thickness.

And so the vacuum insulation works: Vorgepresste Welded plates of microporous silica under vacuum into a gas and water vapour density film. The resulting vacuum insulation Panel has an extremely low thermal conductivity at a coarse vacuum from 1-10 mbar. A 20 mm vacuum Panel insulates as well as 200 mm high quality mineral fiber (MF) or 150 mm of polyurethane foam (PUR)! The U-value of this high-performance insulation is thus approx. 10 x better than the rigid polyurethane foam, mineral fibre or polystyrene foam. Even if damage to the vacuum, the micro-porous silica has still a very high insulation value. Vacuum insulation panels are however very sensitive without any protection and require great care in processing. For this reason, vacuum isothermal Ltd. has developed since 2005 for the most diverse areas of application VakuVIP panels are protected against external damage.

So, for example the land be protected on both sides with a rubberized mat (vakuVIP gum-2), and can be laid as floor insulation. In this laminated version, they are accessible even during the installation. Product vakuVIP SP2/E, the vacuum insulation Panel is protected in addition to surface protected by polystyrene in the area by a circumferential EPS Einleimer. The Einleimer enables also a shipping plugs of the VIP’s on the ground. Vacuum insulation panels can be adapted subsequently dimensions no longer, therefore, after carefully planning all plates optimally specially made to measure and supplied with an installation plan. Vacuum insulation products, climate quite thin!
