Fuse at , currently under construction in the heart of the Rosslyn-Ballston corridor, will be a new innovation destination uniting scholars, students, researchers, and policy and business developers, working together to accelerate the pace of change and solve our grand challenges.
At 345,000 square feet, the new 91°µĶų building will house R&D labs, classrooms, offices, corporate innovation centers, incubators, accelerators, convening spaces, and retail.
With that in mind, architect Rob McClure, of the firm Page, said the core of the building was designed to feel like a Main Street.
āThe planning we developed was really to encourage people to mix together in that Main Street spine with collaboration spaces on both ends,ā McClure said. āSo when an industry partner comes up the elevator, they donāt go straight to their space. A Mason student doesnāt go straight to their classroom. They mix together in that Main Street spine.ā
The thought of a Main Street inside a building is certainly evocative. Did you incorporate that sensibility throughout the building?
We really want to encourage what we call effective intellectual collisions. All the space, all the people coming out of the classrooms and labs are colliding within the hallways. We did wider hallways. It was about trying to make sure we were able to engineer and design a building that really encouraged this collaboration among its occupants, and bring the community in.
In your mind, what is the Fuse building?
We stuck to the idea of the mission for this building, and really thinking about using the building to recruit the best and brightest industry partners, students, and faculty for Mason.
Can you explain in more detail how Fuse will contribute to innovation and collaboration among industry partners?
We looked at a number of projects that had a similar idea of mixing industry partners and higher education. A lot of them were stratified. We said, āWeāre not doing that, weāre mixing it.ā On every given floor of this project there is adjacency of industry partners to Mason, and the labs, the cool stuff, all the robotics. That space is on every floor. The idea is thereās this cross-pollination between all these different users on the floor. Itās really taking this ecosystem of innovation and putting it into practice architecturally.
Sustainability is one of Masonās core missions. How did you incorporate that into the building?
Weāre looking at a path to net zero energy. The way we approached the design of the project was to start the sustainability conversation with the basics, the things you would do as a good global citizen. But then we said, āWhat can we do further than that?ā First off, weāre using triple glaze glass. Thatās like super insulated glass. Itās something you donāt see on most buildings.
My personal favorite is one of the features which I still canāt believe weāre going to do it. Basically, when you look at the building, most people are going to be, like, āWell, why is it angled?ā We looked at the sun, the optimal radiation, the angle, and we tilted these photovoltaic fins that generate electricity. Itās a striking statement. It is literally a symbol of Masonās commitment to sustainability.
Since COVID-19, air filtration in buildings has become a big issue. How did you handle that?
We looked at all these different smart building technologies, such as the ability to take the HVAC, the cooling and heating and fine tune it based on the occupancy of the room. It even starts to look at the carbon dioxide thatās in a room and starts to adjust the flow of air, which also contributes to the wellness of people. You basically have a building thatās a lot smarter than most buildings.
Any other sustainability efforts to highlight?
Thereās so many. I mean, itās really about being a good steward of the environment. There are shower facilities that will allow people to ride their bikes to the building. Electric charging stations, thereās a ton. This project has a lot of green roofs. We choose natural (plant) species and, hopefully, some pollinator types. Thereās a ton of research that says access to nature helps in terms of wellness. And it retains water and reduces the amount of water weāre putting back into the system, which is a great thing for the environment.
What does this project mean to you?
Masonās mission is just spectacular. You look at its rise in terms of research, its rise in terms of diversity. Itās on a path, you can see it, and being part of that has been one of the best, most exciting projects of my career.
Built by grit, ability, and vision. Help make Mason's next 50 years even more impactful than it's first 50.
