Project Summary

School building prototype that is energy efficient, sustainable and life-cycle cost effective.

Project Highlights

  • Geothermal HVAC system
  • Solar water heating
  • Daylighting features
  • Integrated Building Automation System


This elementary school prototype was designed to meet the standards required for a LEED Platinum rating. The project team considered all aspects of the design of an energy efficient, sustainable and truly life cycle cost-effective school building. Many different models were created to study building types, glass, roofing and structural systems. Later, 14 different HVAC systems were priced and modeled for annual energy usage & cost, including cogeneration and ice storage systems. Geothermal was eventually selected, beating the ASHRAE 90.1-2004 baseline by more than 50% in energy cost, and allowing for tax incentives. Solar energy is used for domestic water heating. Daylighting features are incorporated into all classrooms, utilizing sophisticated lighting controls & stepped ballasts. An integrated B.A.S. monitors building systems for energy consumption.
