Description
Assembly Square will be home to greater Boston’s newest mixed use community, based on environmental stewardship and smart growth principles, just minutes from downtown Boston. Assembly Square will be transformed into a mixed use development that is transit- and pedestrian-oriented with a mix of office, residential and retail uses in a modern new neighborhood. The neighborhood includes a dense urban fabric comprising 1.75 million square feet of build-to-suit office space, 2,100 residential units including luxury and more moderately priced apartments and condominiums, and 500,000 square feet of shops, restaurants and entertainment venues. Active urban streets interspersed with sidewalk cafes, parks and captivating retail connect office, residential and retail uses to a meandering waterfront park, a new MBTA Orange Line station, and ample parking. It’s a contemporary backdrop for business success that’s innovative and convenient. Located within a pedestrian-friendly community, 500 Assembly Square Drive’s benefits to workers and residents include opportunity for greater social interaction and improved personal and environmental health, with lower transportation costs. The sensitive integration of both the natural and built environment provides the best place to live, work and play in New England. Outstanding highway access and visibility, future onsite public transportation, a dynamic riverfront location, and a wealth of retail amenities including casual and fine dining and an international shopping experience make this development a convenient and exciting urban office location. This booklet presents the design of one block within the overall development and then focuses on the office building at 500 Assembly Square Drive.

Block 7 Overview
Block 7 Block 7 is one block within the much greater Assembly Square mixed-use development. This block in itself will include a mix of uses with 200 residential units, 73,745 square feet of retail, 576,000 square feet of office space, and 1,600 parking spaces. As planned, the block will have one residential building and two office buildings sited over a podium of ground floor retail and four levels of above-grade parking. Also, one below-grade level will accommodate additional parking, and some retail space. The three buildings are currently identified as: • 525 Main Street, a 23-story residential building with approximately 200 residential units. • 500 Assembly Square Drive, a 15-story building with 10 office floors totaling 231,000 SF of rentable office space over 4 floors of above grade parking and a ground floor containing lobbies, retail and building service spaces. • 550 Assembly Square Drive, a 19-story office building with 14 office floors totaling 323,400 SF of rentable office space over 4 floors of above grade parking and a ground floor with lobbies, retail and building service spaces.
The three buildings can be constructed all at once or independently. Currently 500 Assembly Square Drive will be the first building built on the block and incorporates the garage ramp system that will be used in subsequent phases. The following pages provide floor plans and describe the full build-out of Block 7.

500 Assembly Square Drive Description Sustainable Means Eco-Friendly and Affordable: The building is designed within a sustainable design framework utilizing
sing. • Increased ventilation provided.
the LEED (Leadership in Energy and Environmental Design) Green Building Rating System® as a guide for developing the following high performance building features:
• IAQ (indoor air quality) Management Plan implemented to protect mechanical systems from contamination during construction. • A carbon dioxide monitoring system insures proper outside air delivery.
Sustainable Site: • The project is within a high density mixed-use development. • The project protects “green field” sites by developing on previously developed sites. • Alternative transportation options include public transportation and preferred parking for efficient and alternative fuel vehicles • Light colored high-albedo materials are used to reduce the heat island effect. • Eventually all parking will be within a parking structure. Water Efficiency: • Water use reduced by more than 30% using low-flow plumbing fixtures. • Irrigation water use reduced by more than 50% using indigenous plants and a high-efficiency irrigation system. Energy & Atmosphere: • Overall energy use reduced below ASHRAE 90.1-2004 standards. • Enhanced building commissioning and verification deployed. • No CFC (chlorofluorocarbon) based refrigerants used. • Energy Credits for renewable energy sources may be purchased. Materials & Resources: • 75% of the construction waste diverted from landfills. • Recycling strongly encouraged. • When possible, construction materials manufactured locally and/or containing recycled or rapidly renewable content. Indoor Environmental Quality: • Air-quality, access to day-light and outside views provided. • Low emitting materials used to minimize impacts of off-gas-

Comprehensive design and construction guidelines will be drafted to educate and assist future tenants in implementing sustainable design and construction strategies for tenant improvements High Performance and LEED-Friendly Features A high-performance building envelope examines function first, responds to surrounding climatic conditions, and allows the aesthetics to evolve from these perspectives. For 500 Assembly Square Drive, the building façade is envisioned as a high performance envelope comprised of glass set into a grid of panelized masonry or precast concrete with accents of spandrel glass, painted metal panels and exterior mullion caps. This presents a strikingly fresh and modern appearance. • Vision glass panels – insulating units with low-E coating and a slight tint to mitigate adverse effects of solar heat gain • Extensive first floor glass–as clear as possible–to provide visibility into the retail / lobby spaces and give the first floor a dynamic street presence • Large glass canopies – projecting from the façade to announce the office lobby. Awnings along the storefronts will relate the building to a pedestrian scale • A decorative screen wall covering the parking garage designed to screen the cars while still allowing natural ventilation • A highly insulated roof – to reduce heat absorption • Green roof design – the low roof of the parking podium may be designed as vegetative roof for both visual and environmental considerations
Interior Components The Office Lobby at 500 Assembly Square Drive will be accented with stone, wood and stainless steel and will include a security / reception desk and building tenant directory. Four passenger elevators, each 3,000-lb capacity with a speed of 350 fpm, will serve floors 1 and 7-14 with a 29.9-second average interval. One service elevator, 4,500-lb capacity with a speed of 350 fpm, will serve floors 1 and 7-14. Two passenger elevators, each 3,000-lb capacity with a speed of 400 fpm, will serve two levels of below-grade parking and six levels of above-grade parking with a 49.8 second average interval. Landscape The proposed entrances for both office buildings will be on Assembly Square Drive. Once complete, the two office lobbies will be interconnected by an exterior arcade with garage access and convenience retail to support the office tenancy. A drop-off lane and landscaped forecourt with street trees, planters, stone paving, decorative lighting, and movable seating will provide satisfying color, texture and other pedestrian amenities. Assembly Square Drive will be transformed into a vibrant, people-friendly street. Building Structure The primary structural system will be comprised of steel framing with composite slabs-on-metal deck. Composite joists will be used in the office levels due to building height constraints. The remainder of the project will consist of standard wideflange beams, girders and columns.
Mechanical / Heating / Ventilation / AC The typical HVAC systems serving the main areas of the building will be an all-air system combination of variable air volume (VAV) terminal units with fan-powered VAV boxes with electric reheat coils at the perimeter, and fan-powered VAV boxes without coils for interior zones. Cooling towers will be located on the roof.
