INTRODUCTION The Lighting Schematic serves as a critical component of the lighting design process. It acts as the main means of communication between the lighting designer, clients, and architects. With this being said, the Lighting schematic for the Ruby Rivers Headquarters serves as a detailed plan that illustrates the placement of lighting fixtures, the types of fixtures to be used, and other design specifications. Additionally, the plan aims to meet various standards such as IES requirements and ASHRAE regulations. The schematic is essential to ensure that the lighting design meets the desired vision and concept of the space as specified by the owners. This report will analyze appropriate levels of illumination, aesthetically choices, occupant safety, and comfort.

PROGRAMMING
INTRODUCTION Ruby Rivers Headquarters is a young and creative marketing firm located in Louisville, CO. The company wishes to create a creative and modern environment that remains approachable to the client. With this in mind, sleek finishes and warm wooden highlights emphasize the duality of the space. The building itself features floor to ceiling fenestration, skylights, clerestories, and windows that allow natural light to flood in. The space features different work environments including entry/reception, a display area, open office space, a teaming area, an employee lounge, a conference room, and executive offices. Each space within the building should promote a different work environment in order to create a fully dynamic environment.
PHYSICAL CHARACTERISTICS OF THE BUILDING: ROOM: ENTRY/RECEPTION SPACE USES The entry/ reception area is the user's first impression of the building. The space is also used as a waiting area and a display area. It should create a positive ambiance

CLIENT GOALS AND REQUIREMENTS: The clients at Ruby Rivers Headquarters wish to create a space that caters to their clientele. The owner requested a lighting scheme that promotes creativity. Simultaneously, the space needs to show professionalism and modernism while still maintaining approachability. Interior features are the main focus of the design and the owner made it clear that the first impression of the space should be impressive without being intimidating. This means that the design also needs to be dynamic. It needs to be welcoming and comfortable while still promoting productivity within the workspace. This duality becomes a common theme throughout the space. Aspen Randolph Designs is qualified to fulfill the needs of the client and the project by examining the space through this lens of dynamic design. Through extensive design programming and a layered understanding of the space, it becomes evident that the design needs to be fluid throughout the space in order to transition between work areas. The finishes of the space reflect the environment and mood of the area. Understanding this is vital to the success of the design and to the company's professionalism.
CONCLUSION In conclusion, the design features multiple work areas and environments that need to be enhanced and highlighted through lighting schemes. The programming of the space reflects the need for a dynamic design that caters to the clientele of Ruby Rivers Headquarters. The seven major rooms, ( the entry/reception, display area, open office space, a teaming area, employee lounge, conference room, and executive offices), each feature different environments where clients and employees will interact within the company. These spaces need to reflect different moods in order for the design as well as the business to be successful.

CONCLUSION In conclusion, the Ruby Rivers Headquarters reflects the need for task specific lighting. The multiple applications of the space require different lighting levels to create a positive experience within the space. Through the categories of Illuminance recommendations, uniformity ratios, glare risk, and usage, it becomes apparent that the lighting throughout the building will have different light levels reflecting different uses of the space. In general, the horizontal illuminance provided throughout the building will range from 100-400 lux. This range of horizontal illuminance promotes productivity, and visibility within the space. In general, the vertical illuminance provided throughout the building will range from 20-150. This range of vertical visibility accounts for different tasks done throughout the space including visual presentations, reception, and kitchen usage.

PSYCHOLOGICAL EFFECTS STUDY
INTRODUCTION The psychological effects of lighting are a large consideration when imagining the Ruby Rivers Headquarters. Both the Circumplex model and strategic lighting choreography can impact visual hierarchy within the space. In combining these factors, visual intrigue is created through ambiance and mood while also enhancing wayfinding abilities. This section aims to further explore both of these factors in relation to psychological effects of light.

LIGHTING METRICS AND ACCENT RATIOS STUDY
INTRODUCTION The goal for this section is to visually compare two rooms to find the optimal visual and psychological experience through illuminance and luminance. Furthermore, this section aims to explore the ways in which we can produce different visual effects through contrast between the objects and backgrounds. Finally, the last goal of this section is to explore ways in which spaces can be evenly lit through a threepoint lighting scheme.
LIGHT METRICS Leading Question: Describe the physical characteristics of the two spaces as well as the lighting setup. Include photos of the space. Answer: The two spaces were identical in setup with a colored sheet acting as the background to a table with a painting on it. The only difference between the two spaces was the color of the sheet. One was black and one was white Leading Question: Describe your visual impressions of each space. Answer: My first impressions of the two spaces were slightly different despite the set up being the same. The white room felt larger in comparison to the black room, but I felt as though the painting was more of a focal point in the black room. Leading Question: Define illuminance and luminance, and indicate why those two metrics are the appropriate ones to use in these two scenarios. Answer: Illuminance refers to the amount of light that is projected onto a surface area, while luminance refers to the total amount of light
ASPEN RANDOLPH DESIGNS

Data Collection:
Leading Question: Explain how your initial impressions compare with the illuminance measurements you took. Answer: My initial reactions and impressions were slightly different than the actual results. Because of the dark color of the room, I perceived the space as having a lower illuminance and luminance measurement. The measurement showed the difference between brightness and illuminance because my eye was deceived by my perception of brightness. With this being said, the white room seemed brighter even though there was an equal amount of light. Leading Question: Explain what do the illuminances you measured indicate about the light source itself. Answer: Based on the illuminance measurements, it is apparent that the 36 degree beam had the highest illuminance concentrated at the center if the beam and disbursed as the measurement got further away from the center. This is why the measurements became lower and lower the closer to the edge of the painting the illuminance reader got.
Data Analysis: The luminance measurements in the black room are more comparable to the white room than I originally expected due to the fact that luminance refers to the light output in all directions. This number doesn’t change between rooms despite the eye's perception of brightness. The illuminance measurements describe the amount of light arriving onto the painting.
ASPEN RANDOLPH DESIGNS
Leading Question: Explain why the luminances you measured vary so much within each painting. Answer: The primary reason why luminance measurements varied so much was because there was a difference in the reflectiveness of the paint/ canvas at different points. The painting was made up of matte paint, canvas, and a gold reflective paint. The readings were different at all of these points despite the materiality and the distance from the center of the light source. Leading Question: Provide a recommendation to the interior designer as to which set up is best to use in the lobby of Ruby River. Answer: I would use a brighter colored wall to increase the perception of brightness within the space. This can make the area seem larger and can highlight the art and signage on the walls.

ACCENT RATIOS:
Final Results:
Accent ratios are used to create visual intrigue within a space. A 20:1 ratio reflects a dominant contrast and is typically used within display and performance spaces. Choosing the proper contrast ratio effects our impressions of a space or object. Figuring out the correct accent ratios can make a space successful or unsuccessful. Leading Question: Indicate the accent ratios you obtained when the black and white backgrounds were used. Answer: We obtained a 125 6.25 fc ratio with the black background and a 150 8 fc ratio with the white background. These ratios were achieved by adjusting the positions of the lights and different bulbs.
→ →
Leading Question: Explain the setup and what you did. Answer: We used a series of light fixtures attached to a lighting rod. The lamps utilized were two 560 Lm 4000k SORA lamps, and a 690 Lm 3000k SORA lamp to create the desired 20:1 ratio.
125 fc: 6.25 fc

THREE-POINT LIGHTING Three-point lighting refers to lighting a subject through 3 different positions. This is the key light, which acts as the main source of light, the back light, which creates depth, and the fill light which mitigates any shadows caused by the other two lights. This strategy is used to create a balanced lighting scheme.
Set up When using the Three-point lighting strategy with the sculpture we set the lights up at an angle. We used a spot beam as the key light to highlight the side of the sculpture’s profile, a flood beam to illuminate the background so that the head was ‘grounded’ within the display, and finally we used another spot beam to fill the shadows.
Equipment: Key light: SORRA SP20-11-100-360-03
Back light: SORAA SP20-11-10D-940-03 Fill light: SORAA SP20-11-10D-940-03
Based on this experiment, I recommend using the 3 point lighting technique to illuminate the display area in the Ruby Rivers Headquarters due to the visual intrigue it creates.

LIGHTING CONTROLS AND CODE COMPLIANCE
INTRODUCTION This section aims to provide recommendations for strategies and devices that have the potential to save energy. The strategies proposed will lower the carbon footprint of the lighting plan whilst still maintaining the same quality of lighting.
Strategy 1: Occupancy Sensors and Dimming Switches The first strategy entails using lighting controls such as occupancy sensors and dimming switches to save energy. The occupancy sensor turns lights off when no one is present and turns them back on when an occupant enters the room. This strategy would decrease the amount of energy needed by cutting the amount of time that the lights would be on. Dimming switches allow luminaires to maintain light levels for longer periods of time.
Workspaces - A lighter colored workspace can promote productivity. Additionally, strategically placed task lighting can eliminate excess light and energy Lounge - A dimming switch in the lounge area can allow for users to adjust the lighting based on user needs and tasks. Conference rooms - Using a dimming solution in the conference lighting can allow for different ambiances to be created while also saving energy.
Strategy 2: Reflectance Increase The second strategy entails utilizing reflectance to increase the illuminance. The colors and materiality of the walls, ceiling, and floors can have a drastic impact on the amount of light that is interreflected throughout the space. This means that less luminaires need to be used to meet lighting requirements therefore, saving energy.
Room-by-room Analysis: Lobby - Lighter walls and higher reflectance can not only improve the efficiency and sustainability of the space, but can also make the space feel larger. Corridor - Occupancy sensors can improve the efficiency of the

CONCLUSION: In conclusion, the lighting scheme does not meet the power allowances provided by ASHRAE. The total luminaire watts in general are higher than the required amounts as specified in generalized charts. This realization means that the lighting schematic needs to be reevaluated to maximize illuminance whilst still meeting ASHRAE and IES requirements. Usage of lower voltage luminaires or more efficient lighting plans need to be implemented in order to meet these requirements in the future.

CONCLUSION
In conclusion, per the request of the Ruby Rivers Headquarters owner, the proposed lighting design supports and reinforces the creative nature of the company while highlighting the interior architectural features. The lighting aims to meet not only the requirements of the owner, but also lighting organizations such as, the IES and ASHRAE that provide lighting and sustainability requirements to ensure the safety and sustainability of the plan. The lighting schematic report considers multiple factors such as color temperature, color rendering index, fixture placement, and light distribution to ensure an optimal lighting design for the Ruby Rivers Headquarters. All in all, after the completion of the project it is evident that there are multiple factors that go into the design of a safe and comfortable space. Moving forward with the project it is important to refine and reevaluate ASHRAE calculations to maximize illuminance and to promote sustainability.
