Friedensreich Hundertwasser , born in Vienna 1928, is a painter, an architect and an environmentalist. His architecture is radically different from the traditional , straight -lined, functional architecture practised, for example, by the Bauhaus Masters. From the very beginning , he has tried by various means to show that radical change in thinking are necessary , possible and realized. Hundertwasser's goal in this architecture is to make and give human dwelling in harmony with nature. his architecture is characterized by avoidance of straight lines, " Window Right", irregular arrangement of windows, onion dom, a wealth of colours and such environmentally -friendly consideration as planting of roofs and realizing of "tree-tenants". hundertwasser sees houses as evolving creations which are to be shaped by their inhabitants. He hates Uniformity. The irregularity is always the guiding principle in his architecture. The Hundertwasser's architeucture express his fundamental belief that we may not simply rob nature of her resources, but that we must also return territory to nature which we habe stolen from her. Roofs, terraces and courtyards planted with vegetation and " tree-tenants" build bridges between man and nature. They influse the architecture with vitality and romanticism and are a statement of a quality rather than a standard of living. It is quite possible to value the architecture of Hundertwasser as an important inspiration, as a sort of turning point in the thoughts and actions of city planners. It's success could be healing shock for the international architectural community, which is hypnotized by technology and abused by the shortsighted interests of ren.tability . Under this pressure, today's architects trend to reduce people to a mere part of the " Dwelling machine", without acknowledging that in the long run such machines eat away at people's souls.uch machines eat away at people's souls.

The purposes of this study were to reevaluate urban traditional houses and to propose direction for the conservation and utilization of urban traditional houses in a way of maintaining historical landscape rather than the value of urban traditional houses as components in expanded urban structure. For these purposes, we identified the characteristics of conservation and utilization of urban traditional houses by representative cases and analyzing them exhaustively, and suggested problems in the cinservation and utilization of traditional houses and solution for them. The current conservation system for Urban Traditional House in the Bukchon area is applied to non-residential Urban Traditional House differently according to the owner's consciousness of conservation because there is no support system for non-residential Urban Traditional House. Accordingly, there should be standardized criteria to maintain the landscape of the Bukchon area in terms of beauty formed by the elevation of Urban Traditional House and the continuity of roofs while accommodating various functions. As in total conservation or partial conservation, the interior remodeling of individual houses may be allowed but the three-dimensional external appearance composed of the outer walls, fences and roofs of Korean-style houses should be repaired and improved in a way of maintaining the image. In order to utilize Urban Traditional House in the Bukchon area, plans should be made in consideration of its location, historicity and tradition. We may expect the utilization of traditional cultural facilities and their surrounding areas as alternative cultural spaces. Such use of individual Urban Traditional House should be extended by linearly and areally and suggest the direction of conservation and utilization.

This study aims to introduce a temperature discoloration roof system and its cooling effect in the summer. Temperature discoloration paints can reverse their colors based on temperature changes. If these paints on the roof surface could color-shift between white in the summer and black in the winter, the indoor cooling and heating loads can be affected by the changes in reflection and absorption of solar radiation. Focusing on the summer period, the study analyzed the cooling effect of applying temperature discoloration paint that color-shifts from white to black on the roof surface of a small experimental building module and compared it to commonly used gray and green roof colors. Results of the experiment showed that the surface temperature of the roof with temperature discoloration paint was lower than the gray and green color roofs by a maximum of 10℃. Furthermore, the indoor temperature of the experimental module with the temperature discoloration roof was lower than the gray and green roofs by approximately 3℃. Findings of the study indicate that the application of temperature discoloration paint to the roof can reduce indoor cooling loads.

This study aimed to explore companion planting to improve vegetable productivity on extensive green roofs through urban agriculture with limited substrate depth. From May to July 2021, the study conducted on the rooftop to evaluate the effects of marigold (Tagetes patula) planting ratio on the growth and pest control of cabbage (Brassica campestris). The experiment plot measured 1 m in width × 1 m in length × 0.25 m in height and 0.2 m in substrate depth. Fifteen plots were planted in varying proportions of cabbage and marigold for three repetitions per treatment: cabbage control (CC), 2:1(C₂M₁), 1:1(C₁M₁), 1:2(C₁M₂), and marigold control (MC). We found that companion planting marigolds with cabbage significantly increased cabbage growth and reduced pest infestation. The study revealed that C₁M₁, when cabbage and marigold have the same proportion, is an efficient companion planting ratio. Companion planting, in which non-crop vegetation manages pests and increases crop productivity, improves natural pest control and preserves biodiversity on rooftop urban agriculture.

In this paper, we propose an example of designing and constructing a roof-type solar power plant structure equipped with a Pseudo-BIPV (Building-Integrated Photovoltaic) shape suitable for use as a roof of a small warehouse with a sandwich-type panel structure. As the characteristics of the roof-type solar power generation facility to be installed in the small warehouse proposed in this study, the shape of the roof is not a general A type, but a right-angled triangle shape with the slope is designed to face south. We chose a structure in which an inverter for one power plant and a control facility are linked by grouping several roofs of buildings. In addition, the height of the roof structure is less than 20 cm from the floor, and it has a shape similar to that of the BIPV, so it is building-friendly because it is almost in close contact with the roof. At the same time, the roof creates a reflective light source due to the white color. By linking this roof with a double-sided solar panel, we designed it to obtain both the advantage of the roof-friendliness and the advantage of efficiency improvement for the electric power generation based on the double-sided panel. Compared to the existing solar power generation facilities using A-shaped cross-sectional modules, the power generation efficiency of roofs in this case is increased by more than 11%, which we can confirm, through the comparison analysis of monitoring data between power plants in the same area. Therefore, if the roof-type solar structure suitable for the small warehouse we have presented in this paper is used, the facilities of electric power generation is eco-friendly. Further it is easier to obtain facility certification compared to the BIPV, and improved capacity of the power generation can be secured at low material cost. It is believed that the roof-type solar power generation facility we proposed can be usefully used for warehouse or factory-based smart housing. Sensor devices for monitoring, CCTV monitoring, or safety and environment management, operating in connection with the solar power generation facilities, are linked with the Internet of Things (IoT) solution, so they can be monitored and controlled remotely.

High temperature and natural sun light are considered as the core conditions for high quality and large quantity of Phellinus baumii production. However still now on there has been a mistake of excessively cutting off the natural light by spreading the closing nets on the mushroom cultivating house. For an example there are many houses where the closing nets under the roofs be extended to cover the sides of the houses, which way prevents the mushrooms in the houses from receiving sufficient natural sun light and getting the temperature sufficiently to grow so that the quantity and quality of the produced mushrooms are lowered even though the mushrooms can grow in those conditions. In order to avoid this mistake, the closing nets must be placed on the roofs of the houses only without dropping them to cover the sides. Further more when the closing nets are placed triply at the beginning stage of Phellinus baumii's growth in the house, the nets restrain the internal temperature of the house going up and intercept the natural bright light flowing into the house so that the growing tardiness occur to the Phellinus baumii. Therefore the roof only must have been covered by the closing net for 65% cutting off the light until May, and then covered by double folded the net for June, triple folded the net for July and August, double folded the net for September, and the single net for October. When the ventilation in the house has been maintained until the house tightly balloon out through controling lifting force of internal air, the Phellinus baumii can grow well while the bed logs themselves aren't dried out. Marketing is also very much important as well as increasing quality and quantity of Phellinus baumii production.

Recognizing the problem that the definition of the term pan-ock does not appear precisely in the dictionary, the definition of pan-ock was established through analysis by analyzing 183 cases of pan-ock searched in the Korean Classics DB and classifying them into buildings and ships. First of all, the 65 pan-ocks classified as architecture were used in various ways, such as residences, religious facilities, jang-pan-ocks, and prisons, depending on their use. Second, the 90 cases of pan-ock related to ships were the concept of houses that combine work and accommodation on ships. Finally, through military installations, literary expressions, and bureaucrats who have seen trains and wagons, Pan-ock uses boards. It can be used for walls or roofs only, or for both walls and roofs. Therefore, it is necessary to consider the case of the Joseon Dynasty with the definition of Pan-ock in the existing dictionary. In other words, Pan-ock refers to "houses, religious facilities, royal tombs, and prisons, with various uses and forms. In addition, it refers to the joining of only the wall or the roof with planks, or the joining of both the wall and the roof," suggesting a broader interpretation of the category.

The temperature of PV modules that integrated into building facades or roof increases that could reduce the electrical efficiency of the PV system. In order to incresae PV system's efficiency it is very important to remove the heat from the PV modules. For this purpose, hot air can be extracted from the space between PV modules and building envelope, and used for heating in buildings. The solar collector utilizing this thermal effect is called photovoltaic-thermal(PVT) solar collector. This paper compares the experimental performance of building-integrated PVT collectors that applied on building roof and facade. There are two different case: a roof-integrated PVT type and a facade-integrated PVT type. The experimental results show that the collected thermal energy of the roof-integrated type was 24% higher, compared to that of the facade-integrated.

zArchitect Kim lung-up used free-curved lines as his architectural language. We can categorize his language into 'overlapped curved lines' and 'juxtaposed circles.' We found that his language was expressed well when he applied a specific material, for example, overlapped curved lines - concrete and juxtaposed circles - brick. Furthermore, using the plasticity of concrete, he built roofs and columns in a curved form. He also created reliefs on the walls out of the characteristics of bricks. It can be evidence that he considered forms and characteristics of materials to design buildings. This research mainly focuses on his design method to use free-curved lines with specific materials based on the analyses of forms and materials applied in his architecture buildings and art works

The paper presents the results of 1:50 geometrical scale laboratory modeling of wind-induced point pressure on the roof of the Texas Tech University (TTU) test building. The nominal (prevalent at the TTU site) wind and two bounding (low and high turbulence) flows were simulated in a boundary-layer wind tunnel at Colorado State University. The results showed significant increase in the pressure peak and standard deviation with an increase in the flow turbulence. It was concluded that the roof mid-plane pressure sensitivity to the turbulence intensity was the cause of the previously reported field-laboratory mismatch of the fluctuating pressure, for wind normal and $30^{\circ}$-off normal to the building ridge. In addition, it was concluded that the cornering wind mismatch in the roof corner/edge regions could not be solely attributed to the wind-azimuth-independent discrepancy between the turbulence intensity of the approach field and laboratory flows.
