ZEB + Building's passive design with external blinds for buildings.
Valema Cable Guide Type
We will send you the materials for the German-made external blinds Valerma, which contribute to meeting energy-saving standards in various countries and have a proven track record in Japan's ZEB (Zero Energy Building).
The external blinds for buildings, "WAREMA," contribute significantly to reducing energy consumption in buildings by addressing three key elements of passive methods required for ZEB: solar shading, daylight utilization, and natural ventilation. They have already been adopted in several ZEB demonstration projects in Japan, receiving high praise for their energy-saving performance and improvement of indoor comfort. 【Points of High Evaluation】 ● By blocking sunlight outside the glass, they prevent indoor temperature rise and maintain comfort. ● They harmoniously blend with the facade design. ● The rich variety of slat colors serves as an effective design accent. ● An automatic solar tracking control system keeps the entire building in an optimal energy-saving state at all times. ● A globally recognized brand of external blinds for buildings, manufactured by the German company WAREMA, acknowledged by star architects worldwide.

basic information
Achieve a life that doesn't rely on air conditioning with high insulation and heat shielding performance. ★ External blinds, a common practice in environmentally advanced Germany. ★ Ideal for the hot summer climate of Japan. Even if you block the intense summer sunlight with indoor blinds or curtains, heat continues to build up near the windows. Relying solely on air conditioning to dissipate this trapped heat is inefficient. The rational method of blocking sunlight from outside the windows is 'external blinds,' which are already standard in environmentally advanced Germany. These external blinds create shade outside the window and share a mechanism with traditional Japanese sunshades like 'yoshizu' and 'sudare,' making them the best solution for solar radiation in Japan's climate. 【In summer, about 70% of energy flows in through the windows. The foundation of energy-saving measures is 'window insulation.'】 You often hear the terms 'high insulation' and 'external insulation.' This refers to buildings designed structurally to be less affected by outside temperatures, allowing for a comfortable indoor temperature with less energy. Among these, the most crucial point for improving a building's energy efficiency is the 'windows.' By blocking heat from direct sunlight in the summer and allowing it in during the winter, significant savings on heating and cooling costs can be achieved.

External blinds for high-rise buildings "Valema" are also active in double-skin facades of high-rise buildings.

Cuts solar energy from window glass by about 80%. The external blinds from "Valema" have a low transmission rate of solar energy, blocking about 80% outside the window. Since 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 accumulates between the window and the blinds or curtains leads 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 considered 100%, then 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.
-
Compatible with 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. With Valema, which can be installed in openings up to 5m, the design of the building can be enhanced while keeping the exterior looking sleek.
-
In addition to a view and a pathway for the wind, privacy is also well secured. Concerned about outside gazes? You can block them by making the interior just a little darker. The inside 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.
