The development of an energy-efficient remodeling framework in South Korea

A Framework for Green Remodeling Enabling Energy Efficiency and Healthy Living for the Elderly

“…The nine application areas of remodeling are furniture planning, openings planning, smart home systems, space planning, There are many different energy-saving strategies that can be implemented in houses. Therefore, architects often have difficulty prioritizing the application of appropriate strategies in the process of energy performance improvement and efficient management [10]. To solve this difficulty for energy-saving strategies, Lechner [20] suggested a three-tier approach including the first tier of basic building design approaches, the second tier of passive systems, and the third tier of mechanical equipment.…”

“…Through smart home systems, such as sensors, devices, and controllers that support the health, culture, and leisure of the elderly, the management of indoor environments and energy, household activities, security and safety, and the physical, mental, and social functions of the elderly could be Energies 2018, 11, 2031 6 of 10 supported [3,30]. Taking into account the color discrimination capability and responses of the elderly, finishing materials and color plans that support the elderly's mental health, such as stress, depression, and memory assistance, should be developed [10,[31][32][33][34][35][36]. The lighting plan should consider proper illumination of artificial lighting to support the elderly's work and activities and local lighting of stairways and floors for guidance at night [35].…”

“…The purpose of this study is to develop the framework for green remodeling for the elderly by identifying elements that are essential for improving energy performance for healthy living. Improving the energy performance of the houses by remodeling is one alternative for solving environmental problems and can have a great effect on the economics of buildings [10]. Further, identifying the area of application and critical components for energy efficiency helps improve energy performance for the elderly through the remodeling process.…”

“…The concept of sustainability in housing often deals with issues such as limited resources, especially energy, to lessen the effects of development on the natural environment [2]. The implementation of sustainability through green building is important in the built environment because green building can increase building energy performance and improve the occupants' health [10]. In Table 1, "Thermal environment" includes the control of temperature and humidity in each space and the use of renewable energy.…”

Two-Stage Integer Programing Model for Building Retrofit Planning for Energy Saving in South Korea

“…In 2010, Korea used 22% of the total energy in building, and the average annual increase amounted to 2.6% [3]. In addition, the building sector accounts for 30% of global greenhouse gases emissions [4]. In Korea, 25.2% of greenhouse gases are generated in the building sector [5].…”
