Cabinet Regulation No. 280 of 2019 on the Latvian Construction Standard LBN 002-19, Thermotechnics of Building Envelopes Country/Territory Latvia Document type Regulation Date 2019 Source FAO, FAOLEX Original source Latvijas Vēstnesis, 135, 05.07.2019. Subject Energy, Environment gen. Keyword Energy conservation/energy production Sustainable development Emissions Climate change Sustainable use Geographical area Europe, Europe and Central Asia, European Union Countries, Northern Europe Abstract The Regulation approves the Latvian Construction Standard LBN 002-19, Thermotechnics of Building Envelopes. This Regulation contains legal norms arising from Directive 2010/31/EU of the European Parliament and of the Council of 19 May 2010 on energy performance of buildings. The Construction Standard prescribes the procedures for the energy efficiency design of the structure elements of external building envelopes and their connections for heated buildings to be newly erected, rebuilt, and renewed, and also for new heated premises to be installed in already built buildings the temperature in which during the heating season is maintained at 8 °C and higher; and the thermotechnical parameters to be used in the calculations during the designing of heating, ventilation, and systems. The purpose of the Construction Standard is to reduce energy consumption in buildings by increasing the efficiency of energy use and to prevent the formation of structural-physical defects in buildings and their structure elements. Energy efficient structure elements limiting carbon dioxide emissions shall be provided for in the construction of buildings. Full text English/Latvian Website likumi.lv
