Penn State Architectural Engineering Senior Thesis Salamander Hospitality Resort and Spa Luke Renwick Lighting/Electrical Option AE Faculty Consultants Dr. Kevin Houser and Ted Dannerth April 7, 2010 2 Executive Summary The Salamander Resort and Spa is a Five Star/Five Diamond resort under construction in Middleburg, VA. When completed, this resort and spa will be the signature building for Salamander Hospitality. The building boasts luxurious interiors, spas, indoor pools, outdoor pool and terraces, a restaurant, wine bar, ballroom, and 168 guest rooms. Salamander Hospitality has requested that this building be LEED certified in environmental and energy efficient design, making it one of the only LEED certified buildings of its kind. Therefore, an interesting mixture of luxury, energy efficiency, and environmental responsibility make up the design strategies for the building. The following report covers several topics regarding aesthetics, energy efficiency, cost analysis, and functionality. The main focus is to provide complete lighting design for four spaces throughout the resort and spa. Lighting design criteria, documentation, equipment, graphics, and performance data are provided for the following spaces: the Entry Courtyard, Living Room, Wine Bar, and Grand Ballroom. The lighting designs for all spaces enhance the architecture and interior design while expressing general themes of relaxation and Virginia horse and wine country, which Middleburg is known for. Beyond the aesthics of the lighting redesign, a daylight harvesting study and photosensor control integration analysis was completed in the Living Room and energy savings were maximized. Existing electrical design was modified to meet the change in lighting design. Branch circuiting panels, feeders, and voltage drop were resized for each space. Also, electrical depth topics are included as additional studies on equipment efficiency, cost, and functionality. As part of the general goal to enhance the interior spaces and complete interdisciplinary studies in the design industry, an architectural breadth study is included in the form of a fireplace and Wine Bar room layout redesign. In addition, a mechanical breadth redesign and heat recover analysis is also provided. The lighting design solutions proved to be aesthetically pleasing, decorative, functional, flexible, technical, and energy efficient. With such a design, the Salamander Resort will one day provide an relaxing and enjoyable experience to their guests. 3 Table of Contents Building Information and Statistics... 5 Lighting Redesign... 6 Entry Courtyard... 6 Design Criteria... 8 Luminaires Design Performance Graphics Electrical Redesign Feeder Sizing Worksheet Living Room Design Criteria Luminaires Design Performance Graphics Electrical Redesign Daylighting Analysis Daylight Autonomy/Continuous Daylight Autonomy Control Integration Switching/Dimming Wine Bar Design Criteria Luminaires Design Performance Graphics Electrical Redesign Ballroom Design Criteria 4 Luminaires Design Performance Graphics Electrical Redesign Feeder Sizing Worksheet Dimming Control Diagram Overcurrent Device Coordination Study Short Circuit Calculation Electrical Depth #1 Static vs. Rotary UPS Electrical Depth #2 Feeders vs. Bus Duct Architectural Breadth Topic Mechanical Breadth Topic Heat Recovery Conclusion References Acknowledgements Appendix A Lighting Plans...

Storage 1117 Lighting Design Design Concept The architecture of the main entrance façade is very traditional and symmetric in style; therefore, the lighting design concept is to mask that symmetry. Non uniform lighting throughout the landscape and on the surrounding buildings facades is used to create interest within the space. Desired Space Perceptions The space should be welcoming. The use of light to accent the landscape and architecture should not only indicate that this area is the entrance to the building, but it should actually catch people s attention and draw them in. 13 Accent/Texture Issues The primary architectural elements of the main entrance façade are the porte cochere, the dormers, and the stone veneer façade. It was very important to accent all three of these elements. The great texture of the stone veneer will pop from the wall grazing luminaires mounted above, under the roof overhang. The porte cochere is accentuated by in grade recessed luminaires that light the columns. The dormers are accented by flood lights mounted on the roof of the two surrounding buildings (see mounting detail). Also, the interior of each dormer, which is not occupied space, will provide a glow to the outside. Finally, the trees within the central courtyard are accented from below, while the trees adjacent to the porte cochere will give a moonlighting effect to the sidewalk below by the tree mounted lumianaires above.

Ft Total Tradable Performance Summary The lighting design for the entry courtyard of the Salamander Resort and Spa sets the tone for the luxury brand of the resort itself. With a mixture of architectural emphasis, decorative lantern luminaires, and landscape lighting, the courtyard is brought to life at night. It not only enhances the aesthetics of the courtyard, but the light is functional in bringing guests into the main entry of the building. A definite increasing hierarchy of light levels causes one to walk toward the main entry. There is adequate light for pedestrians along the perimeter paths and orientation luminaires signifying the driveway for vehicular traffic. Interesting features for the courtyard experience are moonlighting effects from luminaires mounted within trees, fountain lighting that is capable of color changing for special occasions, and the emphasized texture of the stone veneer by use of the wall grazing luminaires. While the roof itself is subtly flood lighted, the warm glow from within dormer windows signifies to guests what experience awaits them. The lighting design is not only qualitatively functional, but meets illuminance and lighting power density criteria. All surrounding walkways receive at least 1.0 footcandle of light, and the porte cochere canopy receives the 5 footcandles that are recommended for unloading luggage at night. The lighting power density for tradable spaces set by ASHRAE 90.1 is 70% of the allowable wattage, meaning that this design is energy efficient. 21 Electrical Redesign Specialty lighting within the Salamander Resort and Spa is circuited to and powered by Lutron GP Dimming Panels, which have the ability to power dimmed or non dimmed circuits to luminaires. All dimming panels used in the electrical engineering design of the resort are 120/208V, 3 phase, 4 wire with main circuit breakers as overcurrent protection. All panels affected by lighting redesign are shown in Table 2 below, with the panels containing courtyard circuits highlighted in yellow. Table 3: Dimming panels affected by lighting redesign.
