“…The most significant barriers to implementation of energy efficiency technologies are resistance to new technology, lack of knowledge and high initial investment costs (Darko et al, 2017). In context of cold climates, a lack of clear retrofitting regulations is also mentioned (Felius et al, 2020). Other challenges in executing energy efficiency investments are overestimating the costs, cost-benefit mismatch caused by information asymmetry and lack of attention to energy costs, among others (Zhang et al, 2018).…”

Buildings and construction are responsible for about 40% of the energy and process-related CO2 emissions worldwide. At present, the renewal rate of building stock is relatively low, for example in Finland, which is the case under study in this work, it is 1.5% per year. With respect to the target of a carbon neutral world by 2050, the effect on emissions of existing building stock must be considered. In this paper, we present the results of analysis of energy efficiency improvement investment in 12 city-owned buildings in two Finnish cities. Using measured heat and electrical energy consumption data, a model was developed for analyzing the impact of active and passive energy efficiency improvement investment options per building. The examined active technologies were heat pumps, solar photovoltaic panels, and heat recovery in ventilation system, and the passive improvement compared was structural improvements in the building envelope. The results show that investments in energy efficiency improvements can reduce the yearly energy-related operating costs of the buildings by 35% on average. The study further finds that usually investment in active energy efficiency improvements provides a bigger return on investment than passive improvements. The profitability of examined measures makes Public–Private Partnership a feasible way to provide funding for renovation of public buildings.Graphical abstract

“…from the 1970s, were usually larger and more compact, often built as two-or threestory houses with a basement and much more energy efficient even in the light of current minimum energy requirements (Pbl2010/TEK17). Therefore, their further improvement in energy efficiency can be achieved without additional insulation of building envelope components today, using alternative and more efficient mechanical components as well as more efficient energy management using building automation [4][5].…”

Upgrading existing one-family houses to higher energy standards can be a challenge for owners, among others, due to the unclear status of technical regulations in the case of retrofitting at the national level. Retrofitting projects face technical obstacles that can be difficult to exclude with sensible measures. As a result, retrofitting projects are more difficult to complete. How can we effectively increase the rate of retrofitting projects for private owned residential buildings? Challenges associated with a complete renovation were listed, analysed and illustrated based on one of the smallest Norwegian typical wooden houses from the 1960s. Optimal packages of solutions for the retrofitting, based on energy simulation models, were proposed. The analysis showed that existing buildings are vulnerable meeting today’s, much stronger, energy requirements equal for all buildings. More attention should be given to the development of separate regulations at the national level as well as to the development of retrofitting solutions, if the goal of increasing the number of renovations is to be achieved. The efficient use of solar energy becomes an important measure, especially in the context of expected climate change, and a key to achieve sustainable energy management and a better indoor climate. To avoid unnecessary cooling loads and ensure optimal thermal comfort for residents, overheating criteria should be included in energy requirements even in cold climates in the near future.

Evaluating and Identifying Climatic Design Features in Traditional Iranian Architecture for Energy Saving (Case Study of Residential Architecture in Northwest of Iran)

et al. 2022

In the last decades, researchers have been considering some fundamental issues such as energy saving, global warming, greenhouse emissions, and non-renewable energy to make models of house environmental standards to achieve a suitable consumption pattern for saving energy. In architecture, using natural energy is one of the essential pillars of design because it was one of the criteria of designing, which was considered on climate and geography, and it has been a high performance of climate adaptation in the modeling of traditional houses. In this research, Azerbaijan (located in northwestern Iran) is selected to evaluate the practical features of traditional Iranian houses designed in the cold climate, and criteria for developing sensible solutions to achieve a suitable design model for energy saving are provided. The primary purpose of this paper is to evaluate and identify the features of climate design in traditional houses in a cold climate, which are suitable residential buildings for energy management, and to identify the components affecting energy saving. The data collection method is based on checklists, observation, considering the orientation, density, solar radiation angle in the region, documentary, analysis of maps, and adaptation of the architectural plan of the studied houses with the pattern of solar radiation in the area. This research discusses the design criteria for future structures and their adaptable measures based on the obtained results. Finally, it is declared that the traditional architectural design model follows the region’s climatic conditions, and considering the current climate and energies, traditional houses were designed; therefore, the best model for maximum use of available energy is climatic design. As a result, suggestions are made regarding residential architecture design to save energy.
