Increase of energy efficiency is Latvia’s national priority and policy instrument that allows reducing consumption of energy and costs, increasing the safety level of energy supply and reducing dependence on import. One of the trends for reducing energy consumption is to increase energy performance of buildings. In compliance with the EU and Latvian political statements, it is required to promote renovation of residential and non-residential buildings. Studies regarding energy performance aspects in the sector of non-residential buildings in Latvia are comparatively rare; however, non-residential buildings form a considerable part of the building stock, and the increase of their energy performance can bring a significant contribution in achieving the national targets. The research analyses the sector of non-residential buildings, their characteristic statistical data, energy consumption and requirements of energy performance standards. To characterise this sector more comprehensively, information on energy performance certificates of buildings issued during the period from 2016 to 2021 has been evaluated, allowing to make general conclusions on the energy performance level of different non-residential buildings and provide proposals for trends to increase their energy efficiency.
Measures on increasing energy efficiency is a way for ensuring sustainable energy supply, reducing emission of gases causing the greenhouse effect, improving safety of energy supply, decreasing dependence on import of energy and promoting the EU competitiveness. Improvement of energy performance of buildings as a direction of activities is provided in national policy planning documents of major importance such as the National Energy and Climate Plan for 2021–2030 and the Strategy of Latvia for the Achievement of Climate Neutrality by 2050. Residential buildings form a considerable part of the total Latvian housing stock – 27 % according to the number of buildings and 44 % according to their area. Therefore, the increase of energy performance of residential buildings is very significant for achieving the national energy saving targets, i.e. a cumulative savings of final energy consumption of about 6 PJ by 2030. The research analyses the sector of residential buildings, their statistical data, the energy consumption and requirements of the energy performance standards. To characterise this sector more comprehensively, information has been evaluated on energy performance certificates of residential buildings issued during the period from 2016 to 2021, allowing the authors to make general conclusions on the energy performance level of residential buildings and to provide proposals for increasing their energy efficiency.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
