Reduced CO2 levels and increased comfort at Carroll Hall in Brooklyn
The first of its kind in New York City, Carroll Hall at 30 Morgan in Brooklyn, NY features indoor and outdoor spaces that are designed to connect people with nature, even while in the city. The design approach, inspired by the merging of landscape and architecture, features an indoor space with natural ventilation and a botanical garden outdoors. A confluence exists between the two spaces so that fresh air can pass through the garden before flowing indoors. While fresh air ventilation in high-density areas has traditionally not been used in the U.S., this building proves that it can be successfully executed. Earlier, in 2022, the project won an AIANY Design Awards in the category: Citation for Reclaiming Urban Space.

Dameron ArchitectureCooling and reducing CO2 levels in buildings with natural ventilation
The primary method to cool the space is through the automated windows and skylights using buoyancy ventilation as the predominant ventilation principle. The fresh air flows in primarily via the facade openings, is distributed throughout the open spaces, and then rises into the air, so that the air leaves the building via the roof openings. The WindowMaster solution uses sensors to measure indoor temperature and CO2 levels while weather stations monitor outdoor conditions. This provides the system with data to determine when the windows should open or close. Elevated levels of CO2 in the built environment are associated with reduced productivity and grogginess for occupants, but opening the windows naturally flushes the spaces with fresh air and connects people to the outdoors.
Intelligent control of windows: MotorLink®
MotorLink® is a communication technology that enables 2-way control and feedback between window actuators and the Building Management System via the MotorController. All WindowMaster control systems are MotorLink® capable with many of our actuators. Click below to learn more and see related products.

Mixed mode ventilation to manage higher people loads
The building’s indoor space is used for private events and can fit around 200 people. With this size of people loads, mechanical ventilation is used to cool the space and optimize comfort when in the warmer months and/or internal heat loads are too high. The natural ventilation solution in the space coordinates with the mechanical cooling system so that the two systems are not working against one another. This is done through a simple on/off command given when internal and external conditions reach certain set points. And even when the mechanical system is at work, the windows can still open to let fresh, outdoor air in, and CO2 out.
