101 Seaport is designed to use 103 kWh/m2, which is approximately 50 percent less energy than the LEED baseline. The building has a highly efficient triple glazed curtain wall, with a U-value of approximately 0.3 W/m2K. The HVAC (Heating, Ventilation and Air Conditioning) system is equipped with heat recovery units and high-efficiency centrifugal chillers. Chilled beams and perimeter radiant heating have been installed in tenant fit out spaces to provide more efficient heating and cooling than conventional all-air HVAC systems that require higher fan power. The building is also equipped with a waterside economizer, which allows the use of “free cooling” from outdoor air when possible to provide cooling and avoid the use of mechanical chillers. Gas-fired condensing boilers help achieve heating efficiencies above 90 percent. The lighting system is designed to use 7.5 W/m2 on average, which is approximately 30 percent below code. The system includes efficient LED lighting and occupancy sensors.
Intelligent energy management
101 Seaport is equipped with a multidisciplinary building automation system that promotes energy efficiency, thermal comfort and occupant safety. The robust system is essential in meeting the energy management demands and HVAC control sequences, and it allows building managers to closely monitor building data to optimize energy use. The system can monitor individual tenant energy use to encourage tenants to use energy more efficiently.
Skanska conducted an embodied carbon footprint for 101 Seaport, which calculated the total footprint to be 57,000 tCO2e. The footprint covered carbon emissions from construction materials, site fuel use, worker transport and waste materials.
Environmentally responsible materials
Low-emitting adhesives, sealants, paints, primers, coatings, floor systems and composite wood products have been used throughout the building. The construction materials have an average recycled content of 33 percent. Materials with high recycled content include the structural and stainless steel, louvers, concrete, sheathing, fireproofing and metal studs. The lobby was built with locally sourced materials, such as reclaimed oak piles from Boston Harbor. 25 percent of the construction materials were classed as “regional” according to LEED standards.
Waste management during construction
The team succeeded in diverting over 96 percent of construction waste from landfill. Skanska’s waste diversion rate target for Commercial Development projects is 96 percent. The waste stream was co-mingled on site due to site space limitations and was sorted at an off-site facility. Much of the mechanical systems, including the main shaft ductwork, were prefabricated offsite, which helped to reduce the creation of waste on site.
101 Seaport is designed to use 40 percent less water than the LEED baseline. Low-flow fixtures, including toilets, urinals and showers, have been installed that annually save over 3,700 liters of potable water compared with conventional fixtures. A rainwater harvesting system provides water for toilet and urinal flushing, the cooling tower and for landscape irrigation. stopping zoloft after 6 weeks
The building’s green roofing and rainwater harvesting system reduces the site stormwater runoff by over 35 percent and removes 90 percent of total suspended solids from the stormwater. The rainwater harvesting system collects rainwater from the building’s roof drains and stores it in a 120 m3 tank in the basement.
Other Green Aspects
Raising awareness of more sustainable buildings
The project has been featured in several industry publications that have focused on the sustainability aspects of the project. The team held site visits for college students during construction, which included the green aspects of the project. why is lasix called a loop diuretic
Reduced heat island effect
The site’s landscaping and canopy trees, green roofing and underground parking contribute to a reduced urban heat island effect in Boston by minimizing the extent of dark and paved surfaces on the site.
The 1,450 m2 roof deck terrace on the fifth floor is planted with green roof trays. Green roofing creates habitats for birds and insects, filter airborne pollution and reduce stormwater runoff.
