    1.2.0 Apartment Lobby 1.2.1 Introduction The apartment lobby serves as a primary circulation area as well as a gathering place for residents and visitors alike. A revolving door from the exterior opens onto an entry space. Coves have been constructed along the sides of this area. An indentation is created in the wall directly in front of the entry to serve as a point of interest. An onyx-clad reception desk is located to the right of the entry for package drop-off and visitor check-in. Corridors in the rear of the circulation space lead residents into the core elevator lobby where apartment access is available. The entire South-facing front facade is flanked by 13’ high bays of low-e insulating glass (See 1.2.3 Architectural Surfaces) that run from nearly ceiling to floor. Walls are finished in textured beige wallcovering with specular marble tiled floors. While residents can easily access the exterior from the circulation area, they may instead choose to take advantage of the seating area to the side of the main entry. This space provides a waiting area for residents or visitors to converse and relax. The seating area is surrounded on two sides by glazing adjacent to the exterior sidewalks and on a third side with glazing adjacent to the skyway lobby. Walls are similar to the circulation area of the lobby while burgundy carpet is installed along the floor. Primary furnishings include small coffee tables, chairs, and couches for lounging. 1.2.2 Space Layout

    1.2.4 Design Concept Design Goals As Broadway Plaza strives to market itself as a “home away from home,” residents should feel cozy and at ease within the lobby space. No matter the length of stay, each time a resident walks into the lobby, he or she should feel that they are coming home again. The common dilemma among all of those who stay within Broadway Plaza is of course, stress. Thus, a warm, inviting, and attractive ambience will keep current residents happy and attract new residents in the cycle of temporary living. Focal points of interest should be created as a source of diversion from stress and as intriguing conversation pieces. In addition to the ultimate goal of the creation of a homelike atmosphere, several technical lighting issues should also be addressed. Appropriate control of lighting fixtures and the ability to create various lighting levels and moods is of extreme importance. Depending on the time of day and/or occasion, Broadway Plaza demands the ability to change the lighting to suit the condition. Flexibility in system control is one way to ensure that all scenarios can and will be accomplished. Another technical issue is that of the lighting’s ability to assist with way-finding. The core elevator lobby provides primary access to the actual residential units. Thus, it is important to direct residents and especially the unfamiliar visitor to this location. Lighting is one such way to accomplish this task. Conceptualization and Sketches The redesign of the apartment lobby provides a prominent focal point upon entering the space. This focus looks to mimic a modern fireplace through the use of colored light and glass along the center wall indentation directly in front of the revolving entrance. The custom-made application as well as the entire atmosphere of the room coincides with a feeling of warmth and “home.” To create this feeling, low CCT’s corresponding to a warmer light are used in the cove applications. Indirect light from these sources does not create unwanted reflected glare in the marble finishes below, and instead, provides ambient light that should prove comfortable. These coves also work to guide the visitor to the core elevator lobby. The dark walls along the corridor are also grazed to further aid in path finding. All of these applications are referenced in Figure 1.2.4a. Meanwhile, the reception area calls for light that sets it apart for easy recognition, but does not distract from the central fireplace. A decorative linear fluorescent pendant directly above the desk helps to direct visitors to the area for all inquires.

    Like the circulation space, the lounge area also creates a living room type atmosphere. Subpoints of interest are created by the spotlighting of artwork. Decorative semi- indirect pendants, meanwhile, glow above the occupants’ heads to provide enough light for reading and other tasks. Floor lamps coinciding with the pendants above and keeping with a home-like style, provide additional light should it be desired (Figure 1.2.4b.) Control of the entire lobby lighting system is also provided (See 1.2.6 Equipment.)

    1.2.5 Design Criteria • Appearance of Space and Luminaires (Very Important)

    As the most prominent space that high-end clients will see, besides the individual apartments of course, the look of the lobby is extremely important. Concentration should focus on the selection of appealing luminaries as well as on the creation of a sophisticated and welcoming atmosphere. The lavish finishes within the lobby should be highlighted while the atmosphere shall remain calm.

    • Color Appearance (and Color Contrast) (Important) With the illustrious finishes in place, the color appearance of the various portions of the lobby should be considered. Wood and stone, alike, should be lit with lamps that bring attention to the tiniest details of the material and never appear to “wash out” the surface.

    • Daylighting Integration and Control (Important) The large curtain wall and massive amounts of glass surrounding the lobby can cause visual discomfort. The entire front entrance of the lobby faces South, making direct sunlight in the eyes of primary concern. While surrounding buildings may work to block out some of the direct sunlight, their height and distance from the structure will potentially still allow direct sun to enter. Due to the tasks to be preformed within the space, however, a large amount of daylight should not pose a major problem.

    • Direct Glare (Important) Whether occupants are reading, waiting, relaxing, or passing through, direct glare from overly luminous surfaces and/or luminaries should be avoided at all costs. As the space itself is considered first class, it is important to keep the occupants from feeling like second-hand afterthoughts.

    • Light Distribution on Surfaces (Important) Distribution of light on varying surfaces is a means to garner attention, guide, and provide a relaxed atmosphere. While the light distribution should not be even over all elements in the space, a hierarchy of luminance should be developed to create an atmosphere of relaxation. This hierarchy should take into account paths of travel and necessary tasks within the space, as well as provide focal attention.

    • Luminances of Room Surfaces (Important) The luminance values of room surfaces are important within the lobby space for both spatial perception and comfort. Likewise, the eye-catching nature of bright luminance surfaces acts as a means of drawing attention and guiding visitors. Additionally, luminances of surfaces must be in correct proportion to avoid uncomfortable eye adjustments. In the lounge area, where reading tasks will take place, the luminance ratio between task and far surroundings must comply with a 1:
