Sustainable Building Design - December 13, 2013

All technology for everyone
All Technology for Everyone”

  • The Innovation Hyperlab was designed to creatively teach students. The construction of a modern, energy efficient building will educate young adults and provide the framework for them to construct new ideas in science, technology, engineering and math using visual, auditory, and kinesthetic techniques…

Design approach and goals
Design Approach and goals

  • Our design team took a practical approach to design a comfortable, cost efficient and sustainable Science and Technology Center. Our goals:

  • Reuse existing site, building, and materials when possible

  • Superior indoor learning spaces

  • Reduce energy consumption with realistic design strategies

  • Achieve LEED Silver or higher

Climate summary
Climate Summary

  • ASHRAE Zone 5B

  • Hot, dry summers; long, cold winters

  • Predominant southern winds year-round

  • 300 sunshine days/year, 26-74o sun angle

Microclimate Summary

  • Southern Pines:

  • Shading during winter months; strong windblock

  • Neighboring Building:

  • Shading during late summer afternoons; reduces leeward wind flow

  • Conclusions:

  • Excellent daylighting opportunity to south; wind-driven natural ventilation not feasible

Site Selection


  • Reuse existing building structure

  • Site is currently undeveloped

  • Parking capacity retained

  • No removal of green spaces

Proposed Building Design

  • Laboratories occupy southern spaces

  • Faculty privacy from students

  • Centrally located mechanical systems reduce ducting/piping losses

Material Selection


Water Conservation

  • Low water usage fixtures, fittings, and appliances

  • Centralized mechanical room reduces pipe losses


  • Recycled and locally sourced materials when possible

  • Low VOC materials for carpets

Entrance & Exhibition


  • Attract guests & incite interest

  • Display student, faculty, or local research

  • Space can double as reception area for small groups and visitors

  • Use of arid plants and dry grasses for landscaping

Laboratory Spaces


  • Open learning environment

  • Windows optimized for daylighting

  • Solar thermal gains in the wintertime

  • Reflective, sound absorbing panels



  • Common space for students and faculty alike

  • Daylighting northwestern monitor

  • Open floor plan allows penetration to lab spaces

PV Array


  • Congregation area and break room

  • Connection to the outdoor environment

  • Offsets building’s electricity

  • First-hand learning opportunity for students

HVAC controls and strategies


  • Utilize winter solar gains from the southern exposure to reduce heating needs in the wintertime

  • Spaces with similar functions, occupancy levels, and thermal gains are zoned together

  • Nighttime flushes / indirect evaporative cooling

Building performance baseline energy model
Building Performance : Baseline Energy Model

  • ASHRAE 90.1 construction (code)

  • No EEMs

Building performance proposed design
Building Performance : Proposed Design

  • Individual EEMs

  • All EEMs together

Windows and shading



  • Energy Simulations performed in eQuest optimized window and shading devices with respect to energy

  • Shading was further analyzed to block sunlight from April-August

  • Daylight windows provide light further into the space

Daylighting Analysis


  • Northwestern clerestory windows provide lighting into the second floor corridor and common spaces

  • Open floor plan and daylight windows provide light all the way into the back of the lab spaces

  • Reduced electric lighting load and daylighting controls help reduce annual electric load while providing adequate lighting for learning environment
