Arthur L. Irving Institute for Energy and Society in Hanover aims for LEED certification

Arthur L. Irving Institute is a new highly energy efficient multi-purpose facility designed by Architects Goody Clancy with the intent to achieve LEED platinum. The Institute is part of Dartmouth College and is located on the East Coast of the United States in Hanover, NH. This building is set to provide an innovative and sustainable example of how to minimize energy consumption while ensuring the students have a healthy and productive indoor climate. Some of the sustainable design approaches used in the building is automated natural ventilation and passive cooling wherever possible to support the mechanical ventilation system, thus making the ventilation concept an energy efficient mixed-mode solution. The Institute opened in March 2022.

Natural ventilation can reduce energy consumptions

The 55,000-square-foot facility spread over 4 levels is built by Turner Construction. All zones with a facade facing the exterior include a natural ventilation solution using automatically controlled facade windows. WindowMaster worked with R&R Window Contractors and H Window Company to supply the automated awning and parallel pop-out windows. Altogether, the natural ventilation system is installed in 38 climate zones such as meeting rooms, workspaces, conference rooms, office areas, research labs, café, vestibule lobby area. This, to reduce the yearly energy consumption and to provide a comfortable indoor climate. The natural ventilation principle is a mixture of single sided and cross ventilation.

Precise window control

WindowMaster has delivered approximately 135 low voltage window actuators with MotorLink® technology for this project. The actuators control a mixture of 79 top hung awning windows and 13 parallel pop-out windows. Most of the parallel windows are large in size and therefore demand four actuators per window profile. These four actuators synchronize their operation with the help of the MotorLink® technology, to ensure that the window’s will not be damaged during operation. WindowMaster’s products are fully integrated into the Johnson Controls Building Management System, through BACnet-IP communication. The Johnson Controls BMS supplies the outdoor weather data and indoor zone data (indoor temperature and CO2 levels) to WindowMaster’s NV Embedded® system. This data is used for continuously intelligent control of the automated windows and natural ventilation strategy.

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.
