Lighting Depth

The lighting depth will focus on the lighting design for the four spaces chosen in 160 East 22nd.  The four spaces include: the lobby, rooftop terrace, children's playroom and fitness room.  The lighting design concept is to find balance in each space whether that be through balancing contradicting materials, balancing the occupant’s experience vs. a viewer’s experience, bringing the outdoors in, balancing privacy and relaxation in a not so private or relaxing place, and/or creating spaciousness and brightness in a space that does not allow natural light in.  Specific qualitative criteria and quantitative criteria are addressed in the Lutron Presentation.  Quantitative criteria are referenced from the IES Hanbook and Standard 90.1. 

 

Electrical Depth

The electrical depth involves the redesign of branch circuits to accommodate the lighting changes in each of the four spaces: the lobby, rooftop terrace, children’s playroom, and fitness room. If the loads have been increased in the spaces, the feeders will be resized as necessary. The electrical depth also entails the analysis of implementing a photovoltaic array on the roof where applicable. To perform the analysis, determining the proper location and angle of the array is essential.  Figuring out how much energy the system can produce and determining the payback period (using cost information from the construction breadth) will conclude the feasibility of the system for the building. The final portion of electrical depth involves a short circuit study on a path from a panelboard to the distribution system.

 

Construction Breadth

The construction breadth entails performing a cost estimate of the PV system. Along with the cost estimate, an investigation on the available incentives for the PV system will be performed.  This research will address factors that could lower the original cost estimate of the system.

 

Acoustical Breadth

An acoustical breadth will be implemented in the lobby due to the wood panels that make up the majority of the volume within the space. An acoustical analysis will be performed on the reverberation time before and after ceiling modifications. Ceiling modifications include substituting portions of the wood panels for of Barrisol LED lighting frames integrated with acoustical sheets. By applying this Barrisol solution, the goal is to reduce the reverberation time to provide better speech identification within the space because the entry of the space is located along a busy street in New York City.
