Analysis of errors and inaccuracies in the current edition of the GOST R ISO 7730-2009 standard

The paper analyzes the inaccuracies and inconsistencies of the national standard GOST R ISO 7730-2009 "Ergonomics of the thermal environment. Analytical determination and interpretation of the comfort of the thermal regime using the calculation of PMV and PPD indicators and criteria of local thermal comfort" and similar international standard ISO 7730:2005. These standards are designed to assess the quality of the internal environment in order to comply with international practices both in the field of environmental sustainability and in the field of energy efficiency of construction. The authors have investigated and described inaccuracies and inconsistencies, have proposed their corrections in Sections 4 and 5, which establish the method of calculating the predicted mean estimate (PMV – Predicted Mean Vote) and the predicted percentage of dissatisfied with the temperature environment (PPD – Predicted Percentage of Dissatisfied), as well as in Appendix D, which contains a listing of the PMV calculation program in the BASIC language. The paper has been written in accordance with the recommendations developed during the implementation of the international project KO1089 "Green Arctic Building" of the Cross-Border Cooperation Program.
