“…With the continuous changing of the social background, modern architecture continues to develop rapidly toward a deeper level, mainly including aspects such as architectural composition systems, material changes, spatial forms, and traditional cultural development [16]. However, due to the inadequacy of related theories and the abuse of technology, the current architecture in the process of transformation has shown the problems of ignoring characteristic regional cultures, abandoning ecological advantages, and adopting uniform design techniques [17]. Therefore, while exploring how to design passive energy-saving equipment in combination with local climate and environmental conditions for traditional residential houses, it is also necessary to introduce ecological energy-saving concepts into modern architectural design, which also has practical value.…”

China’s research on and specific implementation of energy saving for buildings are mainly concentrated in urban areas, but according to 2016 statistics, the rural population accounts for 42.65% of the total population, so rural housing has considerable energy-saving potential. However, the degree of attention to the energy consumption of rural houses needs to be improved. Regarding the research on and implementation of passive energy-saving strategies for residences, compared with centralized urban high-rise residences, rural residences mainly have independent courtyards, with a flexible layout and easier transformation. In this study, a system that uses the common cold lanes in traditional villages and buildings’ exterior walls was constructed, and the indoor spaces of courtyard buildings in southern Shaanxi were completely passively cooled in summer. This system can be completely separated from the supply of artificial energy by relying on the accumulation and buoyancy effects of air in patios and cold lanes and the hot-pressure ventilation in buildings to cool the buildings and greatly improve indoor ventilation efficiency. As the building is ventilated and cooled, the air wall formed in the system can effectively prevent direct contact between the outdoor and indoor temperatures and reduce the impact of thermal wall radiation on the interior. In previous studies on the passive design of courtyard houses, scholars considered the effect of thermal wall radiation on indoor temperature in simulations. Therefore, in this study, we also separately calculated whether to consider the difference between the situation with and without wall heat radiation (WHR) when simulating thermal conversion. The final results show that when the cooling system was adopted, the annual cooling load of the whole building was 4786.494 kW·h without WHR. However, with WHR, the cooling load reduction was 2989.128 kW·h, a difference of 1797.336 kW·h.

“…In this regard, when designing passive energy-saving technologies for residential buildings, the local living habits and natural conditions should be fully considered, and energy-saving design concepts should be applied to rural residential buildings [ 17 ]. This is of great significance to the design of modern rural residences [ 18 ]. This research’s main proposal is to establish a new passive cooking and heating system in winter, effectively using production and lifestyle to increase indoor temperature and reduce energy consumption.…”

In China, research on winter heating and energy saving for residential buildings mainly focuses on urban residences rather than rural ones. According to the 2018 China Building Energy Consumption Research Report, rural residential buildings emit about 423 million tons of carbon, accounting for 21% of the country’s total carbon emissions. According to the research on China’s greenhouse gas inventory, the main sources of carbon emissions in rural areas are from cooking and the burning of fuelwood and biomass for heating in winter. In this study, the southern Shaanxi area, which is hot in summer and cold in winter, was selected as the research site, and a fire wall system was planned that combines cooking and heating facilities in residential buildings. The system uses the heat generated by cooking and the heat storage capacity of the wall, as well as the principle of thermal radiation and heat convection, to increase the indoor temperature. The advantage is that the hot air generated is mainly concentrated in the inside of the wall, which reduces the direct contact with the cold outdoor air and avoids excess heat loss. In this study, in addition to considering the influence of the cooking fire wall system on the indoor temperature, the difference in the outer wall with or without solar thermal radiation was also considered. The research results show that the use of a cooking fire wall heating system reduces the annual heat load of the building to 440.8318 KW·h, which is a reduction rate of 7.91%. When there is solar radiation on the outer wall, the annual thermal load of the building is reduced by 1104.723 kW·h, and the reduction rate is 19.84%.

Historic structures are not only a part of our cultural identity, but also a component of our daily life. Most of these heritage presences -objects, buildings, landscapes -are embedded in our habitat, in our cities and are influencing the way we are foreseeing the future. The strategies and methodologies developed for the material conservation of historic structures must be integrated with the projects for tomorrow. It is not only about blending old and new, but about integrating the reshaped, re-informed elements of the past into an evolutionary process. Our office, "Andreescu&Gaivoronschi", has been involved in heritage projects from conserving singular objects to large-scale urban landscaping and landscaping designs. We confronted challenges regarding methodologies, proceedings, material research. During our work we discovered the important, less evident parts of heritage: geometry, visual connectivity, meaning; we also became aware of the benefits of using contemporary art. The goal was to imagine new and meaningful roles for the remnants of the paSt. The paper presents our quest and findings, following a string of projects organized according to scale.
