Lincoln Trail Elementary School
The primary focus of the MEP design at Lincoln Trail Elementary was to reduce energy consumption through the use of building controls and highly efficient equipment.
Fresh air is provided by energy recovery units and VAV boxes which modulate based on space CO2 sensors with the intent to reduce energy by not over-ventilating the spaces. This approach allowed the energy recovery unit capacities to be reduced and in turn provided a lower first cost.
The administration areas utilized water-cooled VRF systems with dedicated secondary pumps that could be enabled when the remainder of the building is unoccupied during periods such as after-school hours, holidays and summer breaks. Pumping strategies were utilized to take advantage loads shifting from large areas like the gymnasium and cafeteria.
High-efficiency LED lighting systems were installed throughout the facility with automatic lighting controls utilizing occupancy sensors as well as automatic time of day scheduling, daylight harvesting and user-adjustable dimming controls. Color tuning lighting controls improve the learning environment of special needs classrooms on demand. Technology systems provide interactive video displays and local audio enhancement in all classrooms and teaching areas.
The building entry is secured with card access control with IP security cameras throughout. The entire facility is protected by an addressable voice-evacuation fire alarm system. Emergency lighting and life safety systems are powered by an on-site generator.
