["DISCLAIMER:"]
["·         This spreadsheet has been developed in the framework of the preparation and revision of the set of EN or ISO standards on the energy performance of buildings, to support the European \"Energy Performance of Buildings Directive\" recast (EPBD-recast, directive 2010/31/EU). "]
["·         It is meant for use by  CEN and ISO technical committee(s) and the working group(s) working on the preparation or revision of the EPB-standard to which this spreadsheet applies. The spreadsheet supports checking  that all equations in the developed standard are consistent and can be linked with other relevant standards. It is not meant to perform a full or partial energy performance calculation."]
["·         The spreadsheet supports the expert user of the standards, in particular those who want to review the content of the standard and those who want to translate the standard to a software, to understand the correct interpretation of the equations and calculation steps in the standard."]
["·         Although it has been developed with care, neither the technical committee(s), nor the working group(s) and experts related to the EPB- standard to which this spreadsheet applies warrant that the calculations and procedures in this spreadsheet are free of errors. The technical committees as well as the working groups and their respective members expressly disclaim any liability or responsibility arising from use of this spreadsheet, or any consequences thereof. Any responsibility arising from the use of this spreadsheet lies with the user."]
["DRAFT VERSION:"]
["·         As long as the associated EPB standard or any of the other EPB standards to which it is directly linked are in a draft stage, this spreadsheet is also a draft version only."]
["WARNINGS: "]
["·         Note that the spreadsheet may not allow testing all calculation options that are possible according to the standard to which it applies. This remark applies in particular but not only to limitations on the number instances of a variable that can be considered. "]
["·         In case of differences, the standard should be regarded as the reference, not the spreadsheet. However, during the standard's drafting phase, shortcomings in the draft standard may have been detected and dealt with in the spreadsheets (ideally, such differences are marked)."]
["·         Note also that these spreadsheets are purely intended for testing and demonstration and therefore not aiming to be user friendly or to be protected against wrong or improper use. "]
["TERMS OF USE:"]
["·         The user is not allowed to redistribute a modified version of this spreadsheet."]
["·         The author(s) would appreciate your feed back on the spreadsheet via the comment sheets for the associated draft standard to be prepared by the national standards bodies during enquiry of the draft standard(s),"]
