The Carlisle Street Parking Garage is a multi-use parking facility with 11 split levels of above grade parking, office, and retail areas at the ground floor and two levels of below grade parking. This project has achieved LEED Silver Certification.
The mechanical systems were designed for maximum flexibility, ease of operation and low operating cost which provided energy efficiency expected from a contemporary state-of-the-art facility that includes: unitary split air conditioning system for offices and retail, condensing boilers, outside air / exhaust air heat reclaim, variable speed pumping and high efficiency motors. The parking spaces are ventilated through a system with variable speed drive fans controlled by a Vulcain carbon monoxide detecting systems. The facility is provided with a dry fire standpipe system. A dry sprinkler system is provided for the below grade parking and wet sprinkler for the ground floor retail. A grey water cistern is provided to collect and store rainwater for re-use to irrigate the landscaping and for parking wash-down. The facility is completed with a central energy management system which incorporated direct digital control loops using a distributed processing networking type system that is capable of monitoring and controlling the HVAC systems.
The utility feeders where brought to the site in a looped distribution typology to a customers owned high-voltage switchgear complete with customer owned dry type 13.8kV-600/347V step down transformer. Distribution was designed to provide for extensive pipe and gutter de-icing to maintain below freezing operation of the facility as well as support 7 future tenant retail spaces and 2 Bicycle storage tenants on the ground level. The building was provided with an addressable single stage fire alarm system with remote annunicator panel provided at the primary fire fighters entrance. Natural gas generator sized for 30 minutes of site standby power was provided in an enclosed room on the ground level. Primary lighting throughout the facility was distributed at 347V distribution. LED fixtures were utilized in driving aisles which featured directional aiming of the light source to ensure that there was no glare in the drivers eye when approaching fixtures, in essence lighting an area from behind the driver (having no forward throw). Distinct lighting zones with motion sensors where provided on each floor to dim the fixtures down maintaining the code required minimum exit pathway light levels when an area was unoccupied. Lighting cutoffs were also designed and enforced for LEED to ensure no light pollution and trespass onto other properties.
