PROJECT SUMMARY

  • summary
    • LIGHTING: Illuminated spaces to satisfy IESNA standards and ASHRAE power requirements
    • DAYLIGHTING: Reduced annual energy consumption by over 50% with integrated photosensor system
    • ACOUSTICS: Validated improvements with alternative flooring; not critical to implement
    • LED STUDY: Alternative general illumination system for labs insufficient
    • ELECTRICAL: MCC designed for mechanical penthouse is not practical
