Space Selected: Spin Room in Recreation Floor of the building (floor 3)

Orientation of the windows: North-South

Orientation of the rows of lights: North-South

Without a direct room called “spin room,” from the chart to the left, the closest I interpreted was an audotorium due ot the lower light requirements, since often spin rooms are very darkly lit with the lights being used mainly for safety.

Spatial Parameters: the size of the space is a large 46’ x 59’ with about a 13.5’ ceiling height. I reduced the ceiling reflectance from the default 80% to 50% due to the darker finishes associated and planned for this spin room.

The demographic is younger and fit individuals who aren’t in need of very high illuminance to be in a safe environment lighting wise

Primarily used Mark Architectural Lighting due to its relevance for the designated program of the space

Iteration 1: Surface Mounted Lumenaire

• High performance surface mounted LED light manufactured by Mark Architectural Lighting.

• Sensor type: passive infrared. This type was chosen due to the motion heavy program in this space and the fact that it is indoors, so it wouldn’t simply be an infrared sensor.

Iteration 3: Modeling with Target Lighting Power Density (LPD)

Iteration 2: Suspended Lumenaire

• Length of Suspension: 3.5’

• Quantity: 4

• Sensor Type: passive infrared. This type was chosen due to the motion heavy program in this space and the fact that it is indoors, so it wouldn’t simply be an infrared sensor.

• Con is the very low LPD that is likely due to the low quantity that is required to not exceed the desired foot candle measurement that is specified.

• This is a high performing LED lumenaire fixture

• Surface Mounted Lumenaire

• Quantity: 126

• Sensor Type: passive infrared. This type was chosen due to the motion heavy program in this space and the fact that it is indoors, so it wouldn’t simply be an infrared sensor.

• Title 24 Code for exercise space listed above: 0.5 W/SF

• This is a high performing LED lumenaire fixture

Reflection

Integration of Iteration 1

Based on a thorough analysis, and considering lost of the variables we have gone over about electric lighting in this module of tech, the Lumenaire and system that stands out the most as the best is the one from iteration 1 with the surface mounted light. While the LPD doesn’t quite get as high as code requires, it still acheives the amount of foot candles that is necessary for the program of the space. Furthermore, the LPD required by code isn’t specified in the given manual for a “spin room” specifically, and based on how most spin rooms are, there is typically always lower lighting requirements with lights existing for emergency and mood lighting primarily. Furthermore, iteration 1 has a good balance in terms of the quantity of lights at 16, since the other two at 126 lumenaires and 4 lumenaires would either be over bearing or too greatly dispersed throughout the room to make a big impact on the space from a lighting perspective.

When inserting the minimum code requirement for an exersice space of 0.5 W/SF, it is possible for the lumenaire from the first iteration reach that number, even though that number likely doesn’t even totally apply to the specific program found in this space. Given the high performing LED nature of the light as well, this option is very good on the environment and from a budget perspective since the power load wouldn’t be as high as some non-LED options. Considering the lighting power density affects the lighting performance of the space by considering the power per square footage that the lumenaire requires, which can also have effects in the energy, comfort, and more factors of the space qualitatively as well as quantitatively. A challenge I foresee with the electric light integration in the space is being able to have enough ambient, indirect light so as not to harm the desired mood and feel of the spin room when occupied for its intended use. There has to be a balance found between code, safety, desired mood in the space, and many more factors.

Project Statement

Balboa Heights is a forward-thinking building introducing not only downtown San Diego, but the built environment as a whole to a large scale innovative, and sustainable mixed-use space. Balboa Heights seeks to answer the project-focused question of, how might we use proven sustainable design strategies to design a cohesive space that uplifts the occupants, and environment, and enhances the community while still helping students fulfill their responsibilities to current and future clients?

Experiential Narrative

Balboa Heights is designed to enhance the student experience, and improve their quality of life through well-designed, and affordable on-campus housing, recreational, and access to a library that goes beyond meeting their academic needs. Law students are under enormous stress, so finding proven ways to alleviate this stress through design measures can go a long way. The student body served is very diverse in many facets, so making sure we are paying attention to many different groups and not prioritizing one in terms of temperatures, accessibility, and more is essential. Furthermore, considering that a large amount of the building program is dedicated to housing, we must consider the diverse living requirements of the students, because as graduate students, there is the potential of many families not only with spouses but with kids as well that would need to be designed for as well. With a vertical park being integrated into all functions and spaces of the building, I want the students to feel a sense of peace and refreshment as they have a connection to nature built directly into their living and working environment. As they move through the building, want them to be able to focus on themselves and their important topics, without hearing extraneous noise from the highway or potentially loud spaces within other parts of the building. Overall, I want the students to feel a sense of ownership of the space and help them feel at home, so they can work on bettering themselves and their community through study, recreation, nutrition, and personal space. The other group of people meant to experience part of this building is the general community, and students that might not live in the housing on the upper floors. With the bottom floor of the building being dedicated to a more public library and cafe space, it is meant to enhance the civic life of downtown San Diego, and encourage important connections between students and the rest of the local community. This bottom floor is expected to be more lively and exciting as people from many generations, backgrounds, and cultures are mixed in a space welcoming to all.
