“…Also, with the spread of urbanization, people spend about 75% of their time in buildings. On a global scale, buildings consume about 35% of natural resources, 40% of energy, 12% of potable water and almost 40% of global carbon emissions (Suh and Kim, 2019;Gassar and Cha, 2020). In this respect, one of the most effective ways for people to live a more environmentally friendly life is to reduce the amount of energy consumed in buildings and the level of greenhouse gasses (GHG) released into the atmosphere (Çubukçu and Tari, 2022).…”

PurposeThe building and construction industry has a significant potential to reduce adverse climate change effects. There are plans to improve the natural resource use and greenhouse gas emissions caused by the buildings by choosing energy-efficient technologies, renewable energy sources and sustainable architectural and constructional elements. This study systematically reviews the patent data for climate change mitigation technologies related to buildings, aiming to detect their relative importance and evaluate each technology in the Y02B network.Design/methodology/approachThe applied approach covers the process of (1) selecting high-impact technology, (2) collecting patent data from the USPTO database, (3) creating a citation frequency matrix using cooperative patent classification codes, (4) linking high-impact patents with analytical network process method, (5) limiting centrality of identifying core technologies from indicators and (6) creating a technology network map with social network analysis.FindingsThe study results show that energy-saving control techniques, energy-efficient lighting devices, end-user electricity consumption, management technologies and systems that convert solar energy into electrical energy are core solutions that reduce the effects of climate change. In addition, solutions that will support core technologies and whose effects are expected to increase in the coming years are energy-efficient heating, ventilating and air conditioning systems, smart grid integration, hybrid renewable energy systems, fuel cells, free cooling and heat recovery units and glazing technologies.Originality/valueMost of the studies on patent analysis have failed to demonstrate any convincing evidence down to the lowest component groups of an entire technology network. The applied approach considers and evaluates each component included in a technology network from a holistic perspective.

“…Furthermore, interest in carbon neutrality and energy supply to buildings and communities based on renewable energy, such as RE100, has recently increased [4]. Among the many types of renewable energy, low-cost solar energy, whose equipment is easy to install, is being actively applied to buildings and in communities [5].…”

District cooling and heating methods that can utilize highly efficient heat pumps and various unused new and renewable types of energy are required to achieve low carbon emissions and zero energy usage in buildings and community units. The technical requirements for the implementation of decentralized thermal networks and heat trading are increasing, both for thermal networks in new buildings and for those remodeled based on existing centralized thermal networks. In this study, a conventional centralized thermal network was implemented as a decentralized thermal network and the possibility of heat prosumers feeding thermal networks was demonstrated experimentally. A real-scale plant was constructed by employing unused thermal energy facilities as prosumers in a school and childcare center based on the existing small-scale block heating and cooling thermal network. The decentralized thermal network and heat prosumer concepts were proven through operation experiments performed on the constructed system in summer and winter. An economic benefit can be achieved by increasing the peak power cost. The experimental results also showed that the proposed bi-directional heat trading reduced carbon emissions by 12.7% compared with conventional centralized thermal systems.

“…erefore, in order to reduce Korea's GHG emissions to 536 million tons by 2030, the Korean government raised its GHG reduction rate to 32.5% (25.7% of the reduction target in Korea in 2016). In particular, the GHG reduction rate in the building sector has been raised from 18.1% (2016) to 32.7% (2018). Moreover, the demand for improved energy performance in the building sector is increasing in Korea [16][17][18][19].…”

“…In particular, the GHG reduction rate in the building sector has been raised from 18.1% (2016) to 32.7% (2018). Moreover, the demand for improved energy performance in the building sector is increasing in Korea [16][17][18][19]. Owing to the abundance of old houses with low insulation performance, residential buildings in Korea consume a high amount of energy per building area (358 kWh/m 2 ), which has been reported to be far above Korea's national building energy policy and even other countries' standards [20][21][22].…”

The energy consumption of low-rise residential buildings in South Korea exceeds the targets set in national policies and the standards of other countries. Moreover, there are insufficient policies in place to improve the energy performance of existing low-rise residential buildings and no means to investigate the current status. A standard model enables cost-effective and fast load forecasting and can also be used to establish long-term policies through evaluation of energy saving in buildings before and after the application of energy policies. This study developed a standard model for predicting energy consumption by reflecting the characteristics of low-rise residential buildings in Korea. The standard model was developed based on reliable related standards, national statistical data, and national reports, and the energy variables applied were validated through a sensitivity analysis. Surveys and field measurements were conducted to investigate the energy usage of 70 households in low-rise residential buildings in Korea, and the developed model was validated through comparison with the actual energy usage data. Consequently, the total energy consumption error rate was 12.67% (R2 value: 0.8164), with a significance level higher than 80%, which indicated that the developed model was highly efficient and reliable.
