Architecture
The Long Beach Public Library is quite literally the focal cornerstone of the Long Beach Civic Center project site when traveling towards the ocean via Pacific Avenue. The library is a two-story rectangular building built atop an existing 2-level 180,000 square-foot underground parking garage. Floor plans are approximately 150’ x 230’ with deep overhanging exterior roofs that provide shading and allow for daylighting within the building. The exposed glued-laminated timber structure and curtain wall envelope systems serve as an open and natural aesthetic appearance connecting the occupants from the naturalistic wooden interior finishes to the vast concrete city beyond its reaches. The open floor plans and high vaulted ceilings in the library will serve as a creative space for individuals, groups, and events. It includes several amenities and resources for the Long Beach City community which includes independent study areas, group study rooms, and technology-driven collaboration rooms featuring 3D printers and a learning lab.

Exterior Walls
The entire façade of the Long Beach library is comprised of a curtain wall of high-performance clear glazing system with no thermal break, aluminum frames, fiber-reinforced cement board panels, and translucent insulated storefront glazing.
In general, the curtain wall consists of a combination of translucent/vision glass, metal panels, and shadow boxes panels alternating per design throughout the system. The glazing system is a four-sided structural silicone glazing system. 4-sided SSG is the curtainwall system of choice for governmental projects demanding high performance requirements demonstrated by a superior glass support system for seismic performance, water and air infiltration, maintenance, and durability.
The glass composition is 1/4” glass, 5/8” airspace, and 1/4” glass. The non-glazed portions of the exterior façade are constructed from aluminum panels with 1” of continuous insulation, a weather barrier and gypsum sheathing on metal studs with batt insulation in the cavity and a layer of gypsum board on the interior. Storefront glazing includes with a 3/8”, ½”, or ¼” low iron monolithic glass.

Roofing System
The roof system is comprised of a PVC roofing water proofing membrane fully adhered to ½” minimum thick overlay board, a continuous polyisocyanurate tapered insulation (rigid R-30 insulation) built on top of a plywood diaphragm set on 18”-24” deep glulam timber beams. The exterior parapet walls will be fitted with aluminum coping at the roof fascia with a charcoal finished sealant. A major portion of the roof will be covered with high performance photovoltaic cells to cut energy cost and use in the building during daily operations

Features
The Long Beach Library is pursuing a LEED Gold certification under 2014 standards. The proposed structures are designed to meet 24+20% energy efficiency standards. The project includes high efficiency photovoltaic cells on the rooftop which are designed to achieve an additional 25% reduction in electricity use on an average sunny day in California. The deep overhanging exterior roofs will provide extensive shading and provide solar protection of the interior to avoid overburdening the mechanical system to allow for performance at an optimal level.
The central atrium that extends up from Level 1 through the extents of the clerestory level per the diagram below allow for maximum daylighting to enter the building. The complete exterior curtain wall system’s combination of vision glazing, and shadow boxes will also maximize daylighting exposure while strategically mitigating excess sunlight at design applicable areas.
Occupant controlled systems exist in most areas of the building to cut down on energy use and cost. Efficient LED lighting systems will be provided in the library including fully digital automatic daylight dimming controls. Manual dimming controls will be available in all spaces with two photo-controlled zones at the perimeter and automatic plug load controls. Stand-alone wall/ceiling mounted occupancy sensors with wall mounted override switches will be included in all restrooms, janitor closets, storage rooms, elevator equipment, and mechanical rooms. Individual spaces will included controlled air ventilation systems. Ventilation to occupied areas will be in accordance with ASHRAE Standard 62.1-2007 are increased 30% to meet LEED targets
Building Statistics II
The construction of the Long Beach Public Library will begin in October of 2016 and conclude March 2019. The general contractor is Clark Construction Group, LLC and the project will be delivered by a design-build method. The use of building information modeling (BIM) under the joint design-build contract between the general contractor and architect is expected to expedite the design process to allow for early fabrication, limited change orders/RFIs, and quick design resolution of constructability issues for expedited submittal approvals throughout the life cycle of the design and construction process. The location of a downtown project provides limited space for equipment access and laydown area. Work and material delivery for each engineered system was coordinated with the construction sequence to efficiency use space available during the construction for optimal work flow and a safe jobsite. The existing below grade parking structure was immediately available for use after selective demolition. The existing below grade levels of the building were used for material laydown and construction staff parking where possible during activity sequencing.
Construction
Efficient LED lighting systems (with Lutron Lighting Control System) will be provided in the library including fully digital automatic daylight dimming controls. Manual dimming controls will be available in all spaces with two photo-controlled zones at the perimeter and automatic plug load controls. Stand-alone wall/ceiling mounted occupancy sensors with wall mounted override switches will be included in all restrooms, janitor closets, storage rooms, elevator equipment, and mechanical rooms. The lighting system will be tied into the Building Management System (BMS) which will monitor load shedding for all lighting. A fully digital master relay panel with many smaller micro panels will be used for a fully integrated lighting control system. Lighting control system will allow emergency lighting to shut off after hours and to dim to 50% during business hours when a space is vacant for greater than 30 minutes. Exit signs and 0.05 watts per square foot of emergency “night” lighting in egress paths remain on at all times.

Southern California Edison (SCE) will have a primary feed underground for the electrical service to the building. A single pad mounted transformer will provide a 1600A 277/480V, 3-phase, 4 wire system to the library. High efficiency solar photovoltaic cells will provide renewable energy for the project; supplying 25% of the daily energy consumption for a typical sunny day in California. The PV system will be interconnected with the SCE grid system via net metering. The emergency power system for the library is a 100kw 277/480V, 3-phase, 4 wire diesel engine generator system. All essential equipment, security, telecom, egress lighting, and fire alarm will be backed up with emergency power.
Electrical
A new central utility plant (CUP) will feed the mechanical system. The general areas of the library are conditioned by a conventional overhead VAV with reheat air distribution systems. Supply air is ducted from a site-built air handler located on Level B1 of the building. The air handler consists of a multi-fan supply fan section, economizer section, cooling coil, pre-filter, and final filter section, air flow measuring station, and VFDs. Relief air fans are also provided for system and building pressurization and balancing. Miscellaneous 2-pipe and 4-pipe fan coil units are provided for conditioning of miscellaneous area not served by the main air handlers for portions of the library. See special systems for unique design requirements at the Miller Room.

The Long Beach Main Library site is built on top of an existing 2 level 180,000 square-foot underground concrete parking structure. The building itself has architectural exposed structural HSS steel columns with an all timber framing system made up of 18” to 24” deep glulam timber girders. 30 existing footings will require re-strengthening. 12” of concrete was removed from the existing footing/slab poured over the footings, new steel and dowel reinforcement were added and the slab was re-poured to accommodate an additional below grade level to house the offices for the building managers and facility engineers.
Fire Protection Water Service is provided by the Long Beach Water Department. One fire water service line will be located in the Library Service yard which is still undergoing design. All areas are supplied by an automatic wet combined system. All sprinklers are quick response type sprinkler heads. Water flow switches are provided for each floor level and zone which included a test drain valve and piping. Portable fire extinguishers, multipurpose dry-chemical type, are provided per NFPA 10 in fire extinguisher cabinets made of stainless steel and no glass. Emergency power systems allow for electrical horizontal fire pumps to operate at design pressure to protect the entire building. See special systems for unique design requirements at the Miller Room.

The Miller Room in the library contains ancient preserved texts that require special space accommodations. The miller room requires a dedicated unit with humidity controls to preserve old paper artifacts at their current condition. An adiabatic humidifier provides humidity control for the space and dehumidification is provided through sub-cooling of the supply air temperature. The miller room will also have a secondary gaseous agent fire suppression type system to prevent damage to artifacts.
A minimal security system is in place to restrict access to facility management areas. A series of card readers and security cameras are in place to prevent access to mechanical and electrical rooms, elevator control rooms, special collections spaces, stairwells, server rooms, back of house storage areas, and at the Miller room.
