LEC

LEC is a planning and certifying computer tool for energetic evaluation of buildings

The evaluation tool offers the possibility to evaluate almost every building and construction part regarding to it’s energetic quality, separated by cooling period and heating period. The evaluation of the buildings under consideration of regional climatic circumstances in strictly based on fundamentals of physics. The calculations are based on results of thermo technical equations

For an official proof of the quality of buildings, an external examination by an independent expert testing centre is required in most parts of Europe. The LEC supports this control system. The applicant can let the expert testing centre prove the results of LEC calculations.

The certificate is an official proof of the energetic quality of your building. Using LEC, for the first time ever it will become possible to evaluate buildings with a system only based on fundamentals of physics and also to compare buildings worldwide. That’s what the certificate stands for. The independent expert testing centre guarantees a proper calculation and will testify the energetic quality of your building by issuing a document which you will receive after the testing process is completed. You can post this document at a prominent spot of your building, by that impressively demonstrating the quality and the value of your building.

You can find a list of independent testing centres in your country at
www.lowenergycertificate.com/countries.

The LEC program was developed by the BBS INSTITUTE under guidance of Prof. Dr.- Ing. Hans-Peter Leimer in collaboration with the Hefei University (China), the HAWK-University Hildesheim (Germany), the South East University of Nanjing (China) and the Sinobau e.V. The development was also supported by econet (China) and PKPM (China).

The software you purchase is valid for one installation at one computer. After installation, the use on other computers is not possible.

By the activation, the software is being assigned to a particular computer. During the activation, the installation wizard sends special information about the software and about hardware setup to the server of BBS International. Part of that information is the language, the version type and the product key of the software along with the IP-address of the computer and information which can be drained off the hardware setup of the computer.

During the activation, the installation wizard sends special information about the software and about hardware setup to the server of BBS International. . Part of that information is the language, the version type and the product key of the software along with the IP-address of the computer and information which can be drained off the hardware setup of the computer. Those data are being saved for a possible later re-configuration. Still, the data are being encrypted before transmission and due to that, the data are not legible by BBS. BBS will not receive any confidential information about your computer.

There is the possibility that you will have to reactivate the software if you change major components in your computer. In that case, you can order a new product key at BBS International which will be free of charge. A re-activation should only be necessary after bigger changes to the computer system. So usually the old license key can be used.

LEC calculates the energy level considering the outer surface only. Other methods such as China GB-50189-2005 calculate a more general use of energy, based not only on the building surface, but also on systems engineering and on political conversion factors.
