The Energy Label shall give each client who sells windows the possibility to issue a simple self-declaration of the energy performance of a window-product family. By entering a few parameters the window (configuration made of frame glass - shading device) will be comprehensively calculated concerning its energy performance. The result is presented by means of a descriptive value and a striking schematic divided into energy efficiency classes ranging from A to G.More information
The labelling and classification considers the energy efficiency of the window in winter (heating and solar gains) and in summer (avoidance of overheating by means of shading devices) and gives reference values for the use of daylight.
The evaluation procedure is simple, transparent and is based on a scientific level. It derives from correct and verifiable input data. Basis for the evaluation of the energy efficiency is the standard ISO 18292: 2010-12 Energy performance of fenestration systems for residential buildings – Calculation procedure established by the international committee ISO TC163 SC2. Heat losses and solar gains are balanced on the basis of a building simulation to energy parameters for the heating and cooling period and energy efficiency classes are formed.
The Energy Label consists of a self-declaration of the energy performance. It is based on the data independently given by the creator/company/factory for whom/which the Energy Label will be created. Furtheron the user receives the related file of the Energy Label to be used as label or attachment to the delivery documents. Less information
Contractual precondition, basis, conclusion and prices
The following documents/files are requested for the creation of an Energy Label:
- Company logo in format: PNG, JPG or GIF, RGB-Mode - Dimensions: max. W x H 260 x 130 pixel, File size: max. 500 KB - Energy parameter of window and shading device (U-value(s), g-value, tVIS, gt-value ...) - Suitable self-adhesive labels in the format 190 x 61 mm for printing of the Energy Label may be ordered online with e.g Labelident (Product designation: „Unprinted binder label”, Article number: EB190x061LYW). Link
Presently the creation of an Energy Label is free of charge.
Area of application and period of validity
The Energy Label created exclusively applies to the product indicated in the declaration (window configuration made of frame glass shading device). By sampling the provider regularly checks individual documents for plausibility. He reserves the right to declare Energy Labels that have been created unvalid and to mark them unvalid in the Internet listing visible to each user.
Agreement on the publication of the Energy Labels created
All Energy Labels created by the provider will be published on our homepage www.ift-service.de under Show Energy Labels created. They will not be anonymised. With his data sent online the user gives his consent for the publication. Please email any suggestions and tips for improvement of the Energy Label to an email@example.com with the subject line Energy Label.
