EXECUTIVE SUMMARY This analysis investigates the daylighting potential of 4 different rooftop monitor combinations for the Billings Valley Federal Credit Union—Custer Branch, located in Billings, Montana. As directed by Ed Gulick of High Plains Architects, PC, we were provided with 16 options. Through examination of the combinations, it was determined that 4 of the 16 options would provide the most accurate picture to describe the daylighting qualities of the possible rooftop monitor designs. Those options are as follows: Each option was simulated through AGI32 using a basic 3D model. The following pages present a summary of the simulations used to demonstrate the daylighting qualities. The simulations were conducted based on the lobby and surrounding offices. The simulations were conducted for each combination during June 21st, September 21st, and December 21st, each at 9:00 a.m., 12:00 p.m., and 3:00 p.m. The appendix contains the complete simulation calculation grids for each time period. Calculation points were spaced 2’-6” apart from each other in an orthogonal grid. Calculation grids were located at 3’-6” above the floor in the lobby [takes into account for cabinetry and solid surfacing heights from Revit model] and at 2’-6” above the floor in the offices and support spaces.

GENERAL ANALYSIS PROCEDURE The Revit model, provided by Ed Gulick of High Plains Architects, PC, was simplified using Revit Architecture 2014 to remove unnecessary fixtures, surfaces, and so forth. The Revit model was then exported into AGI-32 for daylighting analysis. The simulations were conducted based on the lobby and surrounding offices. The simulations were conducted for each combination during June 21st, September 21st, and December 21st, each at 9:00 a.m., 12:00 p.m., and 3:00 p.m. The calculations were done with clear sky conditions in Billings, Montana [45° N, -108° W]. The surface conditions and material reflectance are listed in the table below. The data was analyzed by the percentage of points in between 10 and 500 footcandles in the lobby space. Moreover, the data was examined for the points between 50 and 100 footcandles, which is the range of adequate lighting in a typical office building. Calculation grids were also reviewed in the spaces surrounding the lobby for quality of daylight and possible areas requiring mitigation strategies.

RESULTS AND RECOMMENDATIONS Overall, we recommend selection of Option 1 [North Orientation, 30% Light Transmittance] for the lobby space of the Billings Valley Federal Credit Union—Custer Branch. Each monitor combination examined will achieve adequate daylighting with typically 80-90% of calculation points between 10-500 fc. Further examination of the data indicated that Options 1 and 3 provided 90% or more of calculation points within this range [see tables below]. Of those two options, the iso-footcandle charts were reviewed in the area where the teller stations are located. Option 1 provided the greatest levels of illumination 50-100 fc or slightly greater in comparison to Option 3, which less frequently provided such levels of illumination. The calculations also provided insight into areas possibly requiring mitigation strategies where daylight transmittance might become problematic. The following are possible considerations: 1) The offices on the south side of the building [rooms 103 to 107] achieve illumination values well above the recommended quality
standards, sometimes reaching into the thousands of footcandles. Such transmittance of light may cause thermal comfort and mechanical load issues, as well as glare. One possible mitigation strategy includes exterior shading devices to reflect light before it is transmitted into the building. Another strategy is interior view-preserving shades, which provide the benefit of occupant control depending on comfort.
2) The monitor in all combinations will achieve illumination levels into the thousands of footcandles during certain parts of the year. In the case of Option 1, these values are found during the June calculations. Similar to the offices, it would be valuable to consider operable exterior or interior shading devices to mitigate the adverse results of such high illumination values.
Enclosed are the iso-footcandle charts, calculations, and some renderings from the simulations for review. Please contact us for further discussion of these simulation results and possible design considerations.
