3 1. PROJECT DESCRIPTION

4 1301 Pennsylvania Avenue Project Description CONCEPT 1301 Pennsylvania Avenue is defined by its lightness, transparency and clean lines. It represents a new attitude towards the work environment, one that is responsive to the urban situation, which treats the work space as an extension of the city, and which provides comfortable light filled spaces within the form of a simple yet refined building Pennsylvania Avenue is not revolutionary, but different. An intervention into the fabric of Pennsylvania Avenue and Washington DC, the massing connects to the larger urban fabric of Washington. It is not about reference and conformity to an established aesthetic but about quality in materials and details. The formal aesthetic is achieved through a rich layering of materials. The massing is defined by a simple and elegant glass façade. Fixed stainless steel screens overlay the glass façade defining the corner and establish the rhythm along 13 th Street. An active glass screen gives the building a strong presence along Pennsylvania Avenue creating a window to Freedom Plaza while clearly identifying the building as an office building. Performance, not aesthetics is the prime generator of the façade. The high performance façade combine s advancements in glazing with intelligent façade concepts responding to solar orientation, employing natural ventilation and achieving a high level of occupant comfort while simultaneously reducing energy consumption. Through the integration of Architecture and Engineering, 1301 Pennsylvania Avenue elevates systems and materials to a level of art. The result is a singular building of clarity, integrity, and authenticity. Formally simple and elegant, technologically advanced and environmentally responsible, 1301 Pennsylvania Avenue is a building that is of our time. LOBBY / RETAIL The two-story lobby establishes the major presence along Pennsylvania Avenue. Retail uses are planned along 13 th Street at both the Ground Level toward the south and Level 2 toward the north. All retail entrances are on 13 th Street in order to preserve the dignity of the office entrance and Pennsylvania Avenue. Access to the three lower garage levels is midblock along 13 th Street. The remainder of the Level 2 space not accessible from the street is dedicated to office uses and a fitness center. TYPICAL OFFICE FLOORS The center core building is planned to maximize flexibility and efficiency. The Typical Floors at Levels 7 11 have approximately 24,975 rentable square feet. All required building services and support spaces are efficiently planned in a minimal core. The result is tenant spaces with maximum flexibility. Column free lease spans range from feet. Office spaces along Pennsylvania Avenue are planned without perimeter columns maximizing views up and down Pennsylvania Avenue. Floor heights are 11-6 allowing for a clear ceiling height of 9-0 on Levels 2-11.

5 Levels 12 and 13 are set back from the Pennsylvania Avenue Façade by 50 as mandated by zoning. The resulting floor area is approximately 18,992 rentable square feet. The idiosyncrasies of the zoning ordinance height restrictions allow these two levels to have a higher floor height and a resulting clear ceiling height of 9-6 on Levels 12 and 13. The Pennsylvania Avenue Setback allows for a south oriented private terrace and green roof on Level 12. Level 14 houses the Penthouse for mechanical equipment as well as a 1,300 square foot multi-use entertainment space and a second roof terrace overlooking Pennsylvania Avenue available to all building tenants. LOWER LEVELS Tenant parking is provided at a ratio of 1 self-park space per 1,600 rentable square feet at levels P1, P2 and P3. Parking for 13 bicycles is provided immediately adjacent to the 13 th Street entrance to the Lower Parking Levels. Incoming services are arranged along Pennsylvania Avenue and 13 th Street taking advantage of the existing service points. Loading access is from 14 th Street through the existing National Place Service Zone. Loading occurs at the Ground Floor Level with direct access to the service elevator and core. FAÇADE TECHNOLOGY The restrictions of the site and the goal to maximize the building area dictate the building footprint and form. An advanced façade becomes the only visible and technological way to express and achieve sustainability. This way sustainability can be achieved through design. The façade is comprised of two systems. The basic system is a full height flush glass façade developed on a 10-foot module. Each module consists of two components, a fixed glass panel of 8 0 in width, and operable window of 2-0 in width and an 18 slab edge spandrel. The 2-0 operable window is shaded where solar load is a factor by fritting or a vertical stainless steel screen that defines the street facades, while the 8-0 fixed panel is clear low-e glass creating a highly transparent connection with the outside. The second system, along Pennsylvania Avenue, is a twin-shell facade that acts as a thermal buffer space to reduce heating loads in winter and cooling loads in summer, while also extending the natural ventilation season without compromising outward views and access to natural daylighting. The outer shell will be supported from the primary structure through a system of vertical tension rods and wind needles resulting in a light and minimal structure. The resulting expression is integral with the building s form and structure, and displays a visual logic that has a clear foundation in performance engineering. The goal is to dramatically improve the quality and enjoyment of the workplace by maximizing views and daylight while reducing energy consumption. SUSTAINABILITY Sustainability is achieved through utilizing appropriate technology and smart design solutions as well as managing the building process. The goal is a building with high performance and less technical equipment, the first step to achieving LEED Gold Certification Pennsylvania Avenue aims to be at the leading edge of high performance in terms of sustainable design, construction, and operation. Building occupants will have access to nearby

6 public transportation, shops and amenities, rooftop green space, operable windows and natural ventilation, high indoor air quality, daylighting, and personal thermal and lighting controls. The building will be highly glazed for access to daylight and views, but will mitigate solar heat gains through use of high performance glass. Lighting energy use will be reduced through daylight sensors and vacancy sensors, and ventilation energy use will be reduced through demand control ventilation. The design strategies are founded in science to yield efficient and comfortable interior environments. CLIMATE SYSTEMS The mechanical system is a Dedicated Outside Air System (DOAS) which utilizes a central chilled water plant to produce 55 F chilled water using high-efficiency electric centrifugal chillers cooled by an adjacent condenser water system. In addition, the central plant has a dedicated outside air air-handling unit with heat recovery. This unit will use 100% outside air during normal operation yet will also have the ability to recycle air from the building for a morning dry out cycle. The DOAS air-handling unit will have a cooling coil, which will be the second stage of cooling following the heat exchanger utilizing the 55 F chilled water. Its final stage of cooling will be a water cooled chiller, which will drive the leaving air temperature of the unit down to 47 F. This low-temperature air is distributed to each DOAS terminal unit to do both ventilation and latent cooling for the building. The sensible cooling will be delivered via 55 F chilled water to each DOAS terminal unit to provide the sensible cooling using the plenum air intake through the sensible cooling coil. The DOAS terminal units ECM motors will allow for reduced horsepower in periods of off-peak operation, perimeter DOAS terminal units will have electric heating coils. The other areas of the building will be serviced by the condenser water system in the building to feed water-source heat pumps and/or self-contained units. Dry pipe systems will be designed for light hazard in office areas, ordinary hazard in parking garages and as required by code for mechanical rooms, storage rooms and penthouses. Dry pipe systems will be provided parking levels, loading docks and chutes. Wet pipe systems will be used in office areas. There will be two-fire service lines from different streets to support the building fire pumps and sprinkler system. A deluge system will be designed to protect those parts of the north and west facades that require one hour protection. Dry-pipe systems will have upright sprinklers with an allocation of one (1) sprinkler head per 80 SF, wet-pipe systems will have semi-recessed and flush-mounted fully recessed heads in the building core. Office space in the building will have semi-recessed sprinklers with an allocation of one (1) sprinkler head per 120 SF. Loading docks and other areas subject to freezing conditions will have dry-pendant or dry-pipe systems. Areas subject to freezing having a ceiling will have dry-pipe system with dry pendant sprinklers. VFD controlled fire pump installation for fire suppression pressure zone will include the electric fire pumps with capacities to `coincide with fire pump controller, jockey pump controller, and automatic transfer switch from regular to emergency power. The fire pump installation will comply with N.F.P.A. Pamphlet 20.
