Cal State Long Beach at a glance

• 2,000 Faculty & 1600 Professional Staff

Project Background

• Funded by campus operating budget and interest from student fee revenues

• Approximately 43,000 sq. ft.• Originally Built in 1954 –

Classrooms and Offices

• $17.1M – Project Costs• $14.5M - Construction Costs• CM@ Risk Delivery Method• Architect: Steinberg Architects• Engineer: P2S Engineering, Inc.• Cx – Digital Energy

Project Achievements

• Seismically unsafe and Posed hazard• Old inefficient envelope and

fenestrations• Old heating system with no cooling

capabilities• Inefficient Systems • Lack of Smart Classrooms

• Seismic Retrofit and Renovation• Better learning environment with

Smart Classrooms• Improved Circulation and Access• Improved Systems Energy Efficiency • LEED Gold Certification

Project Features

• Brown Field Redevelopment Site - Mitigation and removal of all hazardous construction materials previously used.

• Maximized open space - Site is larger than building foot print.

• Drought tolerant landscape with drip tubing and future reclaimed water.

• 95% construction waste diversion from landfill. • Project used certified wood, 25% of all materials

were recycled and from regional sources. • CSULB Green House Keeping Plan• CSULB Green Pest Control Plan• Green Building Tours and Case Studies by

students

Project Features

• Newly configured spaces to meet program requirements

• Community Hub and serves as a template for future campus designs

• Improved Circulation and access• Creation of smart classrooms• Provision of new windows with improved U

factor and SHGC.• Improved envelope efficiency with wall and

roof insulation to reduce loads• Use of campus chilled and heating hot water

infrastructure• Features outside seating areas quipped with

power and data ports and Wifi

Project Features

• Energy Efficient Air Handlers with VAV controls and Economizers

• Demand Control Ventilation• Effective occupancy sensor controls integrated with

VAV system• High efficiency plumbing fixtures• Energy Efficient LED lighting • Occupancy controls and daylight controls to harvest • daylight savings• Pole-mounted LED light fixtures at

walkways/sidewalks • with photocell and programmable time controls• Provision of metering for all utilities to monitor their

consumption • LEED Gold Certification

Energy Performance

• Baseline: 61.07 kBtu/ft2 - yr• Designed: 41.59 kBtu/ft2 - yr• Compliance margin: 28%• Buildings save approximately 150,000kWh and 2000therms annually compared to base building • Simulated savings of approximately $9,421/year for electricity and $599/year for gas.• Equivalent to saving 52MT of Carbon emissions • Onsite renewable energy- 350KW used of onsite PV panels at the

campus. • Secured $50K in Incentives from Savings by Design Program
