External Venetian Blinds - Adding Sustainability and Productivity to Buildings

External Venetian Blinds: Adding Sustainability and Productivity to Buildings
25 Jul 2021
For a long-time, Hunter Douglas has been renowned for its world-class external Venetian blinds. European architects have been recommending these blinds for their excellent solar and light control capabilities and flexibility of design and operation.

The new generation External Venetian Blinds are similar to the existing blind designs, but, they don’t require any special conditions such as deeper stacking, complex installation process or customized electronic components. Not only that, the Hunter Douglas External Venetian Blinds offer a new project colour collection and various slat dimensions as listed below:

50 MM FLEXIBLE SLAT: 50F - The hardware system for tilting, lowering and raising the slats is encased in the headrail.

60 MM / 80 MM, WITH BEADED EDGES - The hardware system for tilting, lowering and raising is incorporated in the headrail.

60 MM / 80 MM, FLEXIBLE SLATS: 60F & 80F - The hardware system for tilting, lowering and raising is incorporated in the headrail.

88 MM, WITH BEADED EDGES - The hardware system for tilting, lowering and raising is incorporated in the headrail. These blinds also feature rolled-in insert which is made using LDPE (plastic) for sound insulation. The slats are designed in a Z shape to provide perfect closing.

100 MM, FLEXIBLE SLATS: 100F - The hardware system for tilting, lowering and raising is incorporated in the headrail.

Motion mechanism: Tilting, raising and lowering movement mechanism is made of high quality durable plastic. The mechanism is designed to prevent slat movement by wind pressure. Stainless steel tilting spring is encased in two different slat suspension rings to facilitate precise and easy operation. When the slats are lowered, they are fully closed, and during raising they are fully open. There is also an option to install automatic tilting device that presets the slats at an angle of 40 degrees and it is automatically reset when the slats are lifted. 

Operation: These External Venetian blinds are operated with a crank rod via universal joint to a self-braking gearbox integrated in the headrail or located at the extreme edge of the headrail. Alternatively, it can be operated with an electric motor (220/240V-50 Hz) that is enclosed within the headrail. These are high quality motors which are thermally protected against overheating and splash proof (IP54). They offer the option to be operated as a single unit or in combination with other blinds. Not only that, they can be integrated into a fully automated central control system through devices such as group controls, solar sensors, anemometers, time switches and relays. 

It is a well-known fact that people love daylight and it provides them a pleasant experience of visual observation of the outside world. Therefore, we have focused on creating solutions that influence the positive emotional sense of people. The system takes into account the discomfort causing factors such as light, glare or reflection levels which at times could be too bright and distracting for optimal working ambiance. 

It is imperative to create workspaces which are comfortable and naturally lit. Through the integration of natural light and viewing, it is possible to improv productivity and reduction of absenteeism. There has already been research on the relationship between the daylighting and productivity. It has been found that the usage of daylight without occurrence of glare leads to productivity enhancement. To further improve the impact, it is possible to integrate the daylight control systems into the sun control solution.

Sustainability & Indoor Environmental Quality: These External Venetian blinds offer great benefits for the environmental footprint of a building including factors like consumption of energy, water, materials and resources. This sustainability impact is achieved alongside enhancing the thermal and visual dimensions of the building’s internal environment. 

These External Venetian blinds are used as an advanced light and energy tool to deliver greater visual comfort and heat control. They can not only reduce glare but, also bring down internal heat levels. They prevent excessive solar heat gain and reduce the energy expenditure for cooling in the summer. While you will still need cooling equipment, the capacity and power consumption is lowered which leads to the reduction in the upfront investment in the equipment. When installed in a colder climate, it can use solar energy more effectively to keep the place warmer. As the icing on the cake, the integration of the Hunter Douglas External Venetian blinds additionally reduces the greenhouse gas emissions of the building throughout its operational life!
