LEED Sustainability

 WMS will be a fully electric building with energy efficient lighting and controls, and advanced metering.  

• The lighting and controls have been designed to reduce power consumption to help achieve the LEED Optimize Energy Performance credit. 

• The electrical service and distribution support a fully electric HVAC and plumbing system eliminating the use of fossil fuels on site during normal operation. 

• Advanced metering allows the school to verify the design and make adjustments in the future to meet energy consumption goals.
  
  

Plantings:  Once established the shrub and tree plantings are drought tolerant species and do not require any additional irrigation.

Permeable pavements will reduce stormwater run-off rates and encourage infiltration into groundwater.

Bioretention areas and a rain garden features diverse plantings and thick soil profile slows run-off and increases stormwater quality.

Classroom ventilation air and exhaust is handled by rooftop energy recovery units.  This energy of the exhaust air leaving the classrooms is recovered at the energy recovery rooftop units to preheat or pre-cool ventilation supply air.

Classrooms have occupancy sensors to modulate dampers in the supply air duct branches as a means of saving energy during periods when the classrooms are unoccupied.

The rooftop units will utilize the demand-controlled ventilation sequence of operation.  This strategy permits the modulation of the outside air dampers and fan speed based on the level of CO2 in the space. CO2 sensors shall modulate the position of the terminal boxes located in the ventilation supply ductwork prior to discharge in the space.

To save energy required to heat or cool outdoor air, carbon dioxide sensors will be employed in the gymnasium, auditorium, and Student Commons to allow a reduction of outdoor air during periods of low occupancy and motion sensors will also be utilized to allow closure of outdoor air dampers when assembly areas are unoccupied.

The kitchen hood exhaust system shall be provided with a variable volume kitchen hood exhaust control system, which is designed to vary the speed of the kitchen hood exhaust fan in response to the intensity of the cooking operations taking place.  Essentially, the fan will operate at higher speeds when higher heat and smoke producing cooking is taking place thus saving significant energy associated with exhaust air volumes and make-up air.
