The TC Williams High School Replacement Project
The TC Williams High School Replacement Project consisted of many different projects all for one building.
The design process allowed HPCC and its subcontractors to continue with Value Engineering ell after the design was completed. These VE ideas were reviewed and approved by both the Owner and Architect, and the savings were distributed among all parties involved.
The project included a state-of-the-art Garden Roof System. The system allows all rainwater to be drained and collected in the Cistern for use with the Irrigation System, as well as the Non-Potable Water Systems and also keeps the roof cool.
The Building Automation System represents the latest technology for both controlling and monitoring the HVAC system for the building. The BAS and HVAC systems are designed to maximize energy efficiency and indoor air quality by employing features such as enthalpy wheels in Air Handler Units, Economizer mode operation, and classroom COS sensors.
Clerestory windows were used on the third floor of both classroom towers, as well as in the Student Commons, to maximize the amount of natural lighting in the building. As part of the LEED Design of the building, this use of natural light helps cut down the use of building lighting thereby saving energy consumption and cost. This and other attributes were instrumental in the project receiving a Silver LEED Certificate.
Temperature monitoring stations of the three different roof systems used report the differences in temperature at each roof surface. This and other information about the building's energy use is viewable by all on a plasma screed "Building Dashboard" located in the Student Commons. The Dashboard graphically illustrates to students the amount of energy which can be saved on heating and cooling by choosing green materials for building construction. Electrical Energy use throughout the building will also be reported and students will see how features like motion sensitive lights and use of natural lighting can have a huge impact on energy consumption.
Over 96% of all construction waste on this project was recycled.
The mechanical system includes four state-of-the-art Fulton Boilers which provide both hot water and heating to the building. A pre-manufactured Systecom pump package was used to support the two chillers and two cooling towers. There are seventeen custom rooftop air handling units and four indoor air handling units to accommodate 315 VAV boxes along with fifty-nine fans.
The plumbing system has over five-hundred various fixtures being serviced and supported by the 455,000 gallon non-portable water system. Rainwater from roof surfaces and HVAC condensate water are collected into the underground Cistern and used by the building for toilet flushing, cooling tower make-up water, and landscape irrigation. There is also a 2,000 gallon underground grease and waste tank that supports kitchen use. This system was nominated for a WBC award and was a favorite with the judges, despite not winning.
