Allen + Shariff provided MEP engineering design for this $3.8M new construction project. The 9,000 SF building is mixed-use occupancy with a two-story restaurant / bar and two (2) two-story condominiums. The second-floor dining area had an exposed roof structure and was wrapped around a floor opening that overlooked the first-floor bar area. Due to site constraints, the ground floor of the facility had open-air grade level parking with building overhead.

A porch on the front of the building served as outdoor dining and was provided with overhead heating. To optimize energy efficiency, variable refrigerant flow (VRF) systems were selected. Each condominium had its own VRF system with ceiling recessed and wall-mounted units. Each condominium had ducted range hoods; and each bathroom had an independent exhaust fan and ceiling heater. The VRF system serving the Restaurant / Bar was composed of ceiling recessed, cassette style, and concealed ducted units. The kitchen had two cook lines, and each was supported with their own make-up air units, kitchen hoods and exhaust fans. A dedicated outside air system (DOAS) unit was provided to supply the delta of air needed between total kitchen exhaust and make-up. A separate exhaust system was installed for the restroom grouping. Due to the tight constraints of ceiling cavities, ductwork was installed in the basement and above the roof. Some of the recessed VRF units had to be the style that fit between rafters.

Hot water serving the restaurant is provided by an ultra-high efficiency gas water heater utilizing a recirculation line so that hot water is delivered to all fixtures in an efficient manner. Likewise, the fire protection system was zoned between residential and commercial in addition to a dry system that provides full-sprinkler protection to the building.

A new 800A 208Y/120V 3Ø/4W meter center was provided to serve the new spaces. Each apartment was provided with a 125A service, and the restaurant was provided with a 400A service. Additional sub-panels were provided to serve the kitchen and mechanical equipment needs for the restaurant. A new fire alarm system was provided to serve the spaces. New interior and exterior LED lighting was provided, along with ASHRAE compliant lighting controls to serve the building. Additional lighting controls and dimming capabilities were provided for the restaurant to provide better control of the lighting needs for the space.
