Achieving "ZEH" with external blinds "Valema." They are being adopted in succession for model houses that are ZEH-compliant.
The ZETH model house by Kaneko Architectural Industry features external blinds "Valema." To achieve the national goal of converting more than half of new homes to ZEH by 2020, we minimize indoor air conditioning energy by blocking the intense summer sunlight with external blinds, thereby realizing ZEH. **Achieving a lifestyle that does not rely on air conditioning with high insulation and heat shielding performance.** ★ External blinds are common in environmentally advanced Germany. ★ They are also ideal for Japan's hot summer climate. Even if intense summer sunlight is blocked by indoor blinds or curtains, heat continues to accumulate near the window. Relying solely on air conditioning to dissipate this trapped heat is inefficient. The rational method of blocking sunlight outside the window is "external blinds," which are already standard in environmentally advanced Germany. By creating shade outside the window, external blinds share a mechanism with traditional Japanese sunshades "yoshizu" and "sudare," allowing for a cool summer experience and providing the best sun protection for Japan's climate.

basic information
Terms like "high insulation" and "external insulation" are often heard and seen. This refers to buildings that are structurally designed to be less affected by outdoor temperatures, allowing for a comfortable indoor temperature with less energy consumption. Among these, the most important point for energy efficiency in buildings is the "windows." By blocking the heat that enters from direct sunlight in the summer and capturing it in the winter, significant savings on heating and cooling costs can be achieved. 【Roll Slat Specification】【Flat Slat Specification】 ● A type that holds the slats at both ends with cables. ● Steel cables protect the slats from the wind. ● Thin cables provide a neat appearance when stored. ● There are two types of slats: "Sole Slat" and "Flat Slat." (The width of each slat can also be selected.) ● The cable guide type slats have a cable hole for passing the cable, and it is also possible to attach a reinforcing resin part to this cable hole. ● The cables are steel cables coated with plastic on the surface. This protects the slats from the wind. They are securely fixed with a tension angle attached to the lower end.

Cuts about 80% of solar energy from window glass The external blinds from "Valema" have a low solar energy transmission rate, blocking about 80% of it outside the window. Because they are installed outdoors, the air between the window and the blinds circulates, making it difficult for heat to accumulate, thus enhancing heat insulation. In contrast, with indoor blinds, the heat that builds up between the window and the blinds or curtains can lead to a greenhouse effect due to reflection, resulting in an increase in room temperature.
-
The air conditioning operating rate is about one-third when indoor blinds are installed. This can significantly reduce air conditioning costs. If the air conditioning operating rate for a room using ordinary glass (single) without sunshades on the windows is set at 100%, the air conditioning operating rate for a room with external blinds installed is only 25%. Compared to the 75% with indoor blinds, this is about one-third, making it economical.
-
Accommodates a maximum size of 5m x 5m. Large windows are essential for creating an open space that incorporates natural light. However, a large opening can also lead to excessive room temperature increases. With Valema, which can be installed in openings up to 5m, you can enhance the design of the building while keeping the exterior looking sleek.
-
In addition to the view and the passage of wind, privacy is also well secured. Concerned about outside gazes? They can be blocked by slightly darkening the interior. The interior is hard to see from outside, while the outside can be seen well from inside. Changing the angle of the slats does not obstruct ventilation, allowing you to secure privacy while inviting in the pleasant natural breeze from outdoors.
-
Slats are available in 26 colors. The "Valema" slats come in a rich variety of 26 colors. For metal components such as cover panels and guide rails, you can choose from approximately 200 colors. They can be freely coordinated to harmonize with the exterior walls and facades of buildings, serving as accents in design. They contribute to the beautiful scenery of the town through various architectural structures, including single-family homes.
-
Achieve an open view with slat widths of 60mm to 100mm. The standard slat width for blinds is 80mm. While it varies by type, you can generally choose from widths between 60mm and 100mm according to your preference. The ample spacing between slats during use ensures a good view from indoors, even when installed across the entire window, without any sense of confinement. In fact, having the obstruction outside the building allows you to feel the spaciousness of the interior even more than with indoor blinds.
-
Slats with eyelets The cable guide type slats have cable holes (holes for passing cables). It is also possible to attach a resin part called an eyelet to reinforce the cable hole. (Example of flat slats)
-
Fixed with a tension angle. The cable is a steel cable coated with plastic on the surface. This protects the slats from the wind. It is securely fixed with a tension angle attached to the lower end.
