Modern building design emphasizes energy efficiency, comfort and aesthetics. Through ENSNARE we showcase this blend of functionality and design with our innovative façade system. A key feature of this system is the active window, which incorporates a heat exchange and an integrated darkening system. We will explore in this blog post the functionality and benefits of these novel components.

Active Window: The active window within the ENSNARE façade system is designed to be more than just a source of natural light and ventilation. It is a multifunctional element that integrates advanced technology for enhanced energy efficiency and comfort. Key components include:

• Aluminium Window with Thermal Break: The window is designed to meet specific thermal requirements, ensuring minimal heat loss
• Heat Exchanger: The heat exchanger is an efficient active ventilator coupled with heat recovery capabilities. It ensures that the heat from the outgoing air is transferred to the incoming fresh air, maintaining a comfortable indoor temperature while reducing energy consumption.
• Finishing elements: The active window’s contour is finished with specific elements that ensure a seamless integration into the ENSNARE modular façade. These finishing elements are crucial for both aesthetic consistency and functional performance, as they provide the necessary sealing and structural support 

1. Heat Exchanger: The ventilation unit, is a decentralized solution that integrates directly into the window unit and includes:

• Energy-Efficient Ventilation: The system provides continuous ventilation, ensuring a healthy indoor environment
• Heat Recovery: By recuperating heat from the outgoing air, the system preheats the incoming air, reducing the need for additional heating 
• Filtration: The system filters both fresh and vitiated air, maintaining air quality 
• Low Noise Levels: Operating at a noise level of less than 25dBa, the system ensures a quiet indoor environment 

The integration of the heat exchanger involves careful positioning with respect to the façade system. The casing of the heat exchanger is designed to be flush with the façade, ensuring a seamless appearance. This integration required detailed geometric studies to reconcile the manufacturer’s standardized fixing system with the ENSNARE system’s subframe. 

2. Integrated Darkening System

In addition to the heat exchanger, the active window features an integrated darkening system. This system consists of a motorized roll-up screen installed inside the window, beneath the heat recovery air exchanger. The design ensures that the screen does not block the entry of air into the exchanger, nor does it obstruct light or views when retracted. For the Italian pilot site in Sassa Scalo, a motorized roll-up screen was incorporated. This screen is installed under the heat recovery air exchanger and it’s designed to avoid obstructing airflow or light entry. The screen’s dimensions were carefully considered to ensure optimal integration without compromising functionality. 

The ENSNARE façade system’s active window, with its integrated heat exchanger and darkening system, represents a significant advancement in building technology. This multifunctional window not only enhances energy efficiency and indoor comfort but also maintains the aesthetic integrity of the building’s exterior. By integrating these technologies, ENSNARE demonstrates the potential for innovative solutions in modern architectural design, setting a benchmark for future developments in energy-efficiency and sustainable building practices
