Energy-driven refurbishment of existing buildings: review and a solution framework

Sustainable-Driven Renovation of Existing Residential Buildings in China: A Systematic Exploration Based on Review and Solution Approaches

“…Furthermore, building upon this framework, a retrofitting framework based on specific microclimate models for each thermal zone was developed for sustainable refurbishment. Installing adjustable angle sun shading devices, interior sun shading curtains or blinds [40,41] Roof system retrofit EPS, XPS, Rock wool board, Vacuum insulation plate (The thickness of the insulation layer can be referred to Figure 16) Rooftop photovoltaic system [31] Lighting and Control System CFLs and LEDs [22], electronic ballasts [47] Fully automatic control [48] HVAC and other building equipment systems Vertical single-pipe system [26], Ground-Source Heat Pump (GCHP) systems [24,29], Clean heating equipment [50,51] All DC inverter air conditioners [59], solar domestic hot water systems [24] All DC inverter air conditioners [59] All DC inverter air conditioners [59] Intelligent temperature control system [47] Mechanical Ventilation Heat Recovery (MVHR) [28,32], Dedicated Outdoor Air Systems (DOAS) [55] The current research framework on sustainable retrofitting of residential buildings in China requires revision. Additionally, significant differences exist among different climatic zones in terms of building characteristics, economic conditions, and climate factors.…”

“…Here, both options are utilized to assess their impact on the building's energy performance, as shown in Table 6. Furthermore, electronic ballasts can replace traditional magnetic ballasts to enhance the efficiency of lighting systems [47]. Additionally, the implementation of intelligent control systems, such as automatic light sensors and timers, is recommended to automatically adjust the switching of lighting fixtures based on requirements [48].…”

“…Traditional coal-fired furnaces can be replaced with clean heating equipment such as high-efficiency boilers, heat exchangers, natural gas heaters, electric heaters, and air-source heat pumps [50,51]. Intelligent temperature control systems can be installed, adjusting heating equipment operation automatically based on indoor temperature and demand to enhance energy utilization efficiency, albeit at a higher cost [47].…”

“…This only requires residents to improve their energy usage habits and represents a cost-free reform measure with evident benefits [25]. Moreover, installing intelligent air conditioning control systems that automatically adjust the operation of air conditioning equipment based on indoor temperature and demand is another viable approach [47]. Detailed data are summarized in Table 7.…”
