Part 3 of Unwrapping Building 574 is now available! Part 3, entitled Adaptation, talks about the difficulties and nuances of adapting such an old, historic building into a modern, sustainable office. The section also includes some pictures of the building and concludes our series. We hope you’ve enjoyed it!

Not even the interior and exterior details were ignored on the 574 project. The appliances and plumbing will feature energy and water efficient features, and the exterior will feature colored metal paneling for a contemporary look. Carpet, concrete, wood, and a large quantity of supply materials will be recycled goods. All of these elements make for a unique designed, energy aware building.
When I asked about the difficulties of creating such a project, both Santangelo and Kadish were unfazed. “Certainly in such a building, you’re going to have particular issues you don’t know until you work on the building. For instance, we found a 150 by 16 foot storage tank that we had to deal with under a slab, and we don’t know where it came from.” The age of the building though, they assured, was what made the design unique. “Usually we work on the envelope, core, and exterior separately,” Santangelo said “With this building however, the projects have to blend together to address the concerns of the project and incorporate such new parts. This allows us to adapt though, and we even have the ability to include new efficiency concepts rather than go back afterwards and replace something.”
The building, which both assuredly believe will be impressive upon completion, is a great entrance marker for the Tufts campus. With its new design and features, its hopes to showcase the sustainable initiative inherent in the university, and play a new role in the campus’ prestigious legacy.
Our ongoing coverage of building 574 continues with Part 2- Stormwater. The interview details some fascinating mechanics of the building design, including how water and runoff is handled. Read it here!
I asked Ray Santangelo and David Kadish if stormwater drainage was a factor in the design of building 574. “It was actually required,” Kadish said. “The age of the building resulted in a system that sent the storm water to the sewer lines, which is no longer allowed by the city’s code. This resulted in the installation of filtration tanks to mitigate the amount of water being sent to the city’s infrastructure.” Stormwater infiltration systems are used to collect, treat, and recharge stormwater runoff generated from impervious areas of developments, such as roofs, sidewalks, and parking lots. They improve stormwater runoff quality and quantity and help to recharge underground aquifer water supplies, reduce the total volume and peak rate of runoff discharged from a site, and reduce the amount of water directed to City stormwater collection systems.
The conversation also included stormwater recharge systems. Kadish explained these in great detail. “For the 574 Boston Avenue project, there are a few different types of stormwater recharge systems, including pervious pavers, a drywell, and two pipe and stone systems. Pervious pavers allow runoff to infiltrate by providing enough space between each individual paver for water to pass into the underlying soils. A drywell is a concrete chamber with small holes in the concrete walls that drain the chamber. Pipe and stone systems are a mix of perforated pipe surrounded by crushed stone.” Crushed stone is a useful material for infiltration systems because of its high void properties. The more void space a soil has, the more stormwater it can ultimately store and infiltrate. All three types of systems use the same process, which is to collect runoff from impervious surfaces, store it within the system, and slowly let the runoff infiltrate into the underlying soil.
One of the challenges of the 574 Boston Avenue project was to reduce the total amount of runoff offsite. “The Harvard Avenue stormwater system was already overloaded and floods during large storm events,” the men explain. “The City required that we reduce the amount of runoff sent to the Harvard Street stormwater system by implementing infiltration systems to reduce runoff from the 574 site. The infiltration system on the Harvard Avenue side of the project was designed to store a 10-year storm, or 4.6-inches of rain in a 24-hour period.”
This also has ramifications for the building’s LEED rating system, the environmental rating that assesses the green design of a project. Stormwater Quantity ratings require that a site infiltrate at least 25% of the runoff generated by a site. Using the techniques described above, the 574 Boston Avenue project will reduce the runoff sent to the City stormwater systems by almost 60%, a true representation of the design team’s dedication to sustainability.
The Office of Sustainability is proud to present Part 1 of Unwrapping Building 574, a three part blog on Tufts’ current building project.
Building 574 represents the future of sustainability on Tufts Campus, with green initiatives designed into the building. Due to the uniqueness of the site and age of the building, the project requires some unique initiative and planning to make such a concept feasible. Communications intern Timothy Grant interviewed Ray Santangelo, the project manager, and one of the building’s head architects, David Kasdish, on 574 and what it means for sustainability. Even without a background on the subject, the interview is fascinating and easy to follow. Part 1 includes the history of building and some initiatives to include sustainable design.
