“…Similar problems have been discussed in several previous studies. Caro et al [20,21] described the difficulty of improving building elements and the complexity of applying current energy efficiency standards to heritage buildings. With respect to the facade of Kyo-machiya, external insulation cannot be applied without changing the traditional external appearance (a white plaster wall), and there are limited fire-preventative materials that can be used for external finishing.…”

Climate change is an important issue that affects energy consumption, causes health problems, such as heat stroke, and requires urgent countermeasures. Serious health problems, including cardiac arrest, often occur in winter in traditional residences in Japan. Cooling-heating energy is required to maintain a healthy thermal environment. Although energy efficiency standards for buildings have been introduced worldwide to reduce energy consumption and various passive energy-saving methods are being investigated, traditional residences still face difficulties in conducting renovations because of various restrictions, such as the conservation of historical or aesthetic values. In this study, these issues and their appropriate countermeasures were investigated for a traditional townhouse in Kyoto, Japan, “Kyo-machiya” (including its new form “Heisei-no-Kyo-machiya”). The potential of reducing heating and cooling loads was examined by conducting numerical analysis considering residents’ lifestyles. Field surveys of the indoor environment were conducted in both summer and winter. It was revealed that by optimizing the times and positions of opening and closing the windows and indoor partitions, the indoor air flow could be adjusted from both thermal comfort (cooling in summer) and discomfort (cold drafts in winter) perspectives, leading to improving the indoor environment without using energy.

“…3 Recently, the utilization of hybrid systems in buildings to provide a higher proportion of the required energy has attracted interest from researchers. 4,5 Furthermore, the use of hybrid systems also makes it possible to enhance the performance of each individual system as an integrated unit. 6 With reference to the building, based on the high potential of renewable energies, plenty of efforts have been taken to use them in a building to provide a cleaner, sustainable, and at last cheaper way of energy production.…”

In this study, a multicriteria optimization is developed for a hybrid building integrated photovoltaic/thermal (BIPVT) system with a sensible rotary heat exchanger (SRHX) for both heating and cooling purposes. The BIPVT system is considered with and without considering the glass cover. Both the heat and electricity produced by the BIPVT-SRHX system are determined according to the energy and exergy phenomena. The objective functions aimed to be maximized are the annual total amount of generated energy and exergy. The length and depth of SRHX, geometrical parameters of PV modules, and the air mass flow rate are the parameters considered in the optimization. The results reveal a high amount of produced energy for the optimized design; however, the total amount of generated exergy is low. The system with the glass cover shows a higher amount of gained heat and less generated electricity compared with the system without the glass cover. The total energy produced by the system with and without the glass cover is about 227 and 220 MWh, respectively, and the total produced exergy by the systems with and without the glass cover is 1207 and 1585 kWh for the optimized design, respectively.
