This article includes data collected from public and private buildings in Latvia as part of several projects/tenders funded from the governmental Climate Change Financial Instrument (KPFI) of Republic of Latvia. The data provided consists of information on 445 projects, the activities performed therein, as well as numerical data on CO2 emission and energy consumption before and after the projects' implementation. Data cover a period from 2011 to 2020 for various types of buildings. Given the amount, the completeness and the accuracy of data accompanied by qualitative and quantitative information on the funded projects, the datasets could be relevant for evaluating the energy efficiency of the implemented activities and the levels of CO2 and energy reduction. The reported figures could be used for further research on the field of energy performance of buildings and buildings' refurbishments. They could be also taken as case studies by other buildings that plan to implement similar actions.
Keywords: Energy efficiency; Gas emission reduction; Investment financing; Renewable energy sources; Renovation measures.
