1 Executive Summary

1.1 Introduction

Figure 1-1: Welcome Center Site Plan

This Preliminary Design Report (PDR) defines the design maturity of the Seismic Safety and Modernization (SSM) Project at the Lawrence Berkeley National Laboratory (LBNL), also known as Berkeley Lab, in Berkeley, California, in order to develop a more detailed cost and scheduled estimate. The purpose of the project is to improve the safety of Berkeley Lab employees and visitors by addressing existing critical facilities that are currently in inadequate seismic condition; create a new structure to provide a safe shelter in the case of an emergency; create efficiencies through collocation of currently dispersed campus functions; and to improve on-site pedestrian and vehicular traffic safety.

The SSM Project consists of the demolition of the existing Building 54 Cafeteria, the construction of a new approximately 47,500 square foot Welcome Center Building in its place, and the Structural Seismic Upgrade of the existing Building 48 Fire House. The Welcome Center Building will house the LBNL Campus Central Cafeteria, Health Services Department, Badge Office, Operations Office, and contain a Conference Center. The design of the new Welcome Center Building will provide campus users with a welcoming, accessible, seismically complying and ergonomically equitable new “social heart” to the LBNL campus that will take advantage of the extraordinary, sweeping views of the San Francisco Bay.

August 3, 2020 | 9

1.2 Design Status

The major design updates from the Conceptual Design to the current Preliminary Design include:

• Establishment of an early site package to allow for early demolition of the exsiting B54 Cafeteria Building, utility demolition, rough grading and construction of site retaining walls to establish the Welcome Center building pad. This site package is known as the CD-3A, or “A” package, separate from the Welcome Center Building and B48 Seismic Upgrade, known as the CD-3B, or “B” package.

• Change of related site and utility improvement package formerly called the Site Utilities Improvement Package (SUIP), and now called the Transit Hub & Utilities Project (THUP).

• Realigment of the SSM and THUP project scopes which moves the Landscape and fine grading civil design from the SSM to the THUP project.

• Addition of the Badging Department to the Welcome Center Building and renaming of Human Resources to Operations. The overall building size and footprint remains the same.

1.3 Design Approach

The SSM Preliminary Phase started on April 20, 2020, and was developed over 15 weeks through a series of collaborative meetings, focused workshops and weekly meetings. The design team conducted several virtual workshops, including a Sustainability Workshop, a Mechanical Design Workshop, A Universal Design Workshop, a Food Service and Dining Workshop, and a Branding and Messaging Workshop; met with all Welcome Center Users, held focused meetings with the Health Services Department and Mechanical Subject Matter Experts; developed new technical studies to support the development of the Preliminary Design, including a Pedestrain Wind Study, and held Design Progress Presentations.

1.4 Welcome Center Building Area

The Welcome Center Building space program was developed during the Conceptual Design Phase to target a 45,000 gross square foot building. The program was developed using a 70% building efficiency metric appropriate to this building type. The Design Team met with each of the user groups to confirm space needs and quantities. Additional follow up meetings were conducted that resulted in a Program Gross Area of 46,135 gross square feet. The Design Team then developed the building design through site analysis, massing studies and floor plans resulting in an As-Designed Gross Area of 46,485 gross square feet, remarkably close to the space program.

1.5 Building 48 Seismic Upgrade

An ASCE 41-13 seismic evaluation of the Building 48 Firehouse building was performed during the CDR phase in accordance with the University of California Seismic Safety Policy for existing buildings. The seismic evaluation identified the following seismic deficiencies that must be mitigated to achieve the Level II rating:

• Roof framing to CMU wall anchorage. Retrofit details developed in the LBNL 2005 seismic modifications may be assumed for cost estimation purposes.

• Saw-cut openings in original CMU walls that lack trim reinforcement. Retrofit details developed in the LBNL 2005 seismic modifications may be assumed for cost estimation purposes.

• Lack of lateral load resisting element at Lobby structure. Retrofit detail consists of the installation of a braced frame or plywood shearwall lateral load resisting element.

1.6 Design Alternatives Considered

The design team considered the following alternatives during the Preliminary Design phase:

• Department Layout Alternatives

• Food Service Layout Alternatives

• Furniture Layout Alternatives

• Mechanical HVAC System and Equipment Options

• All-Electric versus Natural Gas Kitchen Equipment

• Delivery Truck Sizes and Routes

2.2 Function

The Welcome Center Building proposes to combine four distinct campus functions into a single “one stop shop” for campus staff support functions: Health Services, Operations, Central Cafeteria and Conference Center. In lieu of providing four distinct entries – and four distinct identities – to each of these functions on the project site, the project collocates them within a single Welcome Center Building, accessed through a single main point of entry. This main point of entry functions, in effect, as a single “front door” for the “one stop shop.”

This approach accomplishes two important goals. The first is economy of resources: by planning the multi-functional facility around shared resources – entries, vertical circulation, lobby and circulation spaces, and Building masses – the resources available to the project are more wisely allocated. The second goal is cultural: the layout of space and the choice of architectural systems will provide, where possible, visibility within the Building of the access points for the individual program components. In effect, each of the four main program components will have within the Welcome Center their own highly visible (or, in the case of Health Services, easily located) identity and welcoming “storefront.” Continuous flow through shared undivided spaces free from extraneous doors or other unnecessary barriers to movement and connection, as much as security and other considerations will allow, will help create an environment with a retail-like feel and “dymanic energy.” In addition to attracting campus users with its accessibility, functionality, comfort and retail-like ease of access, the environment of the Welcome Center will offer the LBNL campus community spaces for informal meeting, collaboration, and cultural events.

2.2.1 Departments

The Welcome Center Building will house Health Services, Badge Office, Operations, Cafeteria and Conference Center. These are detailed below.

Health Services Health Services offers a series of clinical programs and services that are available to the benefit of Berkeley Lab employees as well as in support of Berkeley Lab research projects. These include exams and assessments, first aid and wellness, and worker assistance and accommodation. Health Services is currently in Building 26, a seismically deficient structure, and will relocate to the new Welcome Center Building. Health Services also provides initial triage of patients in the event of an accident or emergency and requires exterior access for a gurney to arrive from a nearby Ambulance drop off point.

Badge Office The Berkeley Lab Badge Office issues official LBNL badges, which serve a dual purpose: as an identification badge and as a Berkeley Lab access card. Badges are issued upon verification of employment or affiliate status, and are programmed according to status.

August 3, 2020 | 15

Operations Operations’ mission is to foster the recruitment, retention, and development of exceptional and diverse scientific, engineering, and operational talent through customer focused and efficient human resources support. The Welcome Center will provide space for up to six workstations plus office support functions, and space for records storage.

Cafeteria The Campus Central Cafeteria is currently located in Building 54, a seismically deficient Building, and contains 234 dining seats, serving breakfast and lunch for employees and visitors. The new program will grow in size to 320 interior dining seats to accommodate the growing campus population plus additional exterior dining seats on an adjoining roof patio. A Coffee Bar provides additional beverages and grab-n-go food until late afternoon. The Dining Space is designed to function as a traditional dining space, with a variety of seating options and choices, but also as a destination for informal meetings and collaboration throughout the day.

In addition to a Dining Hall, the Cafeteria program consists of a Servery, Kitchen, Cold Food Storage and Dry Food Storage.

The Cafeteria is recognized as one of the most important collaboration spaces on campus and should be designed not only as a place to eat but a place to meet and work.

The seating will be a combination of moveable tables to allow for large gatherings as well as built-in booths with access to technology for facilitate the work-anywhere concept.

One of the project goals is to achieve zero waste and the Cafeteria provides the best opportunity to design for this. The intent is for use reusable plates and silverware for eat-in diners and reusable containers for take-out diners.

Please refer to the Food Service Narrative in section 5.10 of this report for additional detail.

Conference Center The Conference Center will contain conference space replicating the existing Building 54 capacity plus additional meeting space, including capacity to support conference events of up to 200 people. (The larger events are currently held in off-site conference sites at added cost to the Lab.) The program also incorporates staff to organize the events who are currently located off site as well. The meeting rooms are intended to provide flexibility by having modular rooms with moveable walls to create larger event halls as well as maximize utilization by providing a diversity of room sizes and types. The furnishings for the meeting center will all be flexible, mobile and reconfigurable as to maximize the various space settings and options. It should be noted though that the Conference Center is not intended to replace the 230 person auditorium located in Building 50, nor house the larger User Meeting Events that are sometimes up to 500 people.

IT

A centrally located IT/BDF space within 100m cabling length of all building spaces is centrally located on Level 1.

2.4 Scope Contingency

+/- 10% Scope Contingency allows for flexibility during the award of construction to address low and high awarded bids. The following scope items are proposed for further evaluation as the project develops and inclusion in the final construction documents:

+10% Scope Contingency

1. Add Conference Room Audio Visual Equipment

2. Add Office, Conference and Cafeteria Furniture

3. Add Roof Mounted Photovoltaic Panels

-10% Scope Contingency

1. Decrease Level 1 Building Area and Level 2 Exterior Dining Area by 1 Structural

Bay (2,500 SF)

2. Storage Space at future Conference Center

3. Storage Space at future Badging and Operations Department

4. Defer Exterior Deck Paving

5. Defer (1) Chiller

Decrease Building Area includes all site, exterior and interior construction required for the addition or decrease of Building area.

Creation of Storage Space would be a temporary measure to award a construction contract with the intent to build out that space through additional funds or release of contingency before final construction completion. Storage space would be the reduction of all interior fit out to include department perimeter finishes and minimum MEP, power and lighting. The central MEP systems would still be sized for the future fit out of the storage space.

3 Sustainability LBNL takes active measures to reduce the lab’s climate, waste and water footprint, while improving operations and enabling sustainable solutions. Buildings at LBNL are considered “living laboratories,” where they support, strengthen and apply research, while informing and influencing future projects to improve current operations.

3.1 Requirements

All projects at LBNL are required to comply with the campus sustainability standards, which provide a practical path towards meeting both the DOE Guiding Principles requirements and the University of California Policy on Sustainable Practices. The Welcome Center will comply with the following requirements:

• Meet LBNL Sustainability Standards for New Construction, April 29, 2019

• Follow LBNL Implementation Guide to the Berkeley Lab Sustainability Standards for New Construction, March 2019

• Follow High Performance Sustainable Building per DOE G 413.3-6B

• Achieve LEED Gold Certification

By meeting these requirements, the Welcome Center will also meet the DOE Guiding Principles. The project will not demonstrate compliance with the California Green Building Standards Code (CalGreen).

3.2 Design Targets

As outlined in the LBNL Sustainability Standards for New Construction and the LBNL Implementation Guide to the Berkeley Lab Sustainability Standards for New Construction, all projects have specific sustainability targets that must be pursued. These targets were reviewed with LBNL during a sustainability workshop on March 14, 2019.

The Welcome Center will pursue design strategies that will meet the sustainability requirements and will aim to achieve each established performance target.

All-Electric Building No new Building or major renovation on the LBNL campus shall use onsite fossil fuel combustion for space or water heating. To meet this target, an all-electric building design is proposed for the Welcome Center.

The current basis of design for the kitchen includes natural gas. An all-electric alternative is being carried until a final decision is made by LBNL regarding the fuel sources that will be used. If the natural gas option is selected, then the project is required to document the rationale as required by the UC Policy on Sustainable Practices.

Energy Use Intensity For Federal requirements, the project must exceed ASHRAE 90.1-2013 by a minimum of 30 percent, not including receptacle and process loads. For LBNL requirements, the project must exceed ASHRAE 90.1-2013 by a minimum of 30 percent, including all end

Additionally, LBNL sets Energy Use Intensity (EUI) targets and stretch targets for all projects. The target for the Welcome Center is a 50% reduction from an established benchmark, with a stretch target of a 65% reduction. The established benchmark was developed by assigning an average EUI for each space type, as indicated below, and then weighting the overall total by the total program area for each space type. The established benchmark EUI for the Welcome Center is 95 kbtu/GSF per year. This results in a target EUI of 48 kbtu/GSF per year, and a stretch target of 33 kbtu/GSF per year.

* LBNL Bldg 54 consists of cafeteria and meeting space. The total EUI is 130. The EUI of 143 shown in the table above reflects the weighted EUI for the cafeteria only, once the square footage for the meeting space has been removed. This provides a more representative EUI for the cafeteria space for the purposes of benchmarking.

In the event that a project includes non-typical space types that are skewing the EUI targets, LBNL allows the project to exclude non-typical spaces and/or loads from the EUI benchmark. For the Welcome Center, the proposed kitchen includes equipment loads that result in an EUI of 38, which is 79 percent of the EUI target and 15 percent higher than the EUI stretch target. These loads make the EUI target unattainable. In accordance with LBNL guidance, the project is establishing adjusted targets that remove the kitchen equipment loads from the cafeteria benchmark and from the proposed design. All other end uses are still included in the benchmark and proposed design. With this update, the adjusted benchmark EUI for the Welcome Center is 79 kbtu/GSF per year. This results in an adjusted EUI target of 40 kbtu/GSF per year, and an adjusted EUI stretch target of 28 kbtu/GSF per year.

Compliance with both base EUI targets and adjusted EUI targets will be confirmed using energy models that reflect the predicted, “as-operated” energy use for the building. The “as-operated” energy use may differ from code required assumptions. Energy models are required to be developed beginning at the schematic design, or Critical Decision 2 (CD-

2) phase, and should be updated with building program and material changes at the end of design and at the end of construction administration.

On-Site Renewable Energy New Buildings must be designed to generate at least 7.5 percent of the project’s energy use from on-site renewable sources. At a minimum, the project must be solar ready to accommodate future renewable energy and should create a simple, rectangular area that will allow for the largest, cost effective solar photovoltaic (PV) system on the roof.

Water Use Reduction The project is required to reduce indoor water use by 30-40% over the LEED baseline, to reduce appliance and process use where possible, and to implement landscaping that does not require a permanent irrigation system.

Zero Waste A Zero Waste Plan will be developed by LBNL to help implement campus zero waste goals. In addition to identifying waste management and other practices for daily operations space shall be provided throughout the Welcome Center to facilitate proper sorting and collection of anticipated waste streams.

A Discards Management Plan shall be developed by the design team. The Plan should outline the flow of waste throughout the building and describe how it will be collected. It shall be vetted with the waste management company to confirm that it meets their

100% 3A / 50% 3B Submittal

26 | August 3, 2020 operating procedures and requirements, and that it can accommodate the projected volume of waste that will be generated. During construction, the contractor will be required to divert a minimum of 80 percent of construction and demolition (C&D) debris from the landfill.

Daylighting LBNL established daylighting targets for large lobbies, high bay labs, lab spaces, and private offices / meeting rooms / collaboration / open office areas. The Welcome Center only includes private offices / meeting rooms / collaboration / open office areas, which shall target a spatial daylight autonomy (sDA) of 300 lux for 65 percent of occupied hours for 80 percent of all standard work spaces.

3.3 Design Strategies

The following sustainable design strategies are being considered for the Welcome Center to create a high-performance, sustainable Building that can meet LBNL’s goals and achieve LEED v4 Gold certification:

Sustainable Site Design

• The site will include long term and short term bike storage. Long term bike storage requires a minimum of 4 bicycle lockers and/or covered, secured bicycle racks. Short term bike storage requires a minimum of 15 bike racks. The project will also include showers and changing rooms for staff.

• Landscaping, site paving and stormwater management will follow LBNL standards.

Refer to the Landscape and Civil BODs for additional information.

• The site will include 2 parking spaces with electric vehicle supply equipment (EVSE) to charge electric vehicles.

Water Efficiency and Conservation

• Low flow plumbing fixtures will be used throughout the Building to reduce indoor water use by over 40 percent from the LEED baseline. Given the large volume of visitors, initial calculations show that a 45 percent reduction is feasible.

• The majority of the landscaping will be native/adaptive and will not require any permanent irrigation systems. There are areas of ornamental landscaping, which will be designed as drought tolerant, but for which irrigation is recommended. Refer to the Landscape BOD for additional information.

Energy Use and Conservation The Welcome Center will have all-electrified building systems and a basis of design kitchen that will have limited natural gas for equipment. The project will pursue a stretch target EUI of 33 kbtu/GSF per year, with a minimum target EUI of 48 kbtu/GSF per year.

The adjusted target EUI, excluding kitchen equipment process loads, is 40 kbtu/GSF per year, with a stretch target EUI of 28 kbtu/GSF per year. To reach these targets, the project is proposing design strategies that are relevant to the local climate and to the

August 3, 2020 | 27 individual program areas within the Building.

An energy model is used to determine the predicted annual energy use for the Welcome Center. The 50 percent preliminary design energy model shows that the project is predicted to have an actual operating EUI of 63 kbtu/GSF per year. Of the 63 kbtu/GSF per year that are predicted, 43 kbtu/GSF per year are associated with process uses, including 38 kbtu/GSF per year for kitchen equipment and 5 kbtu/GSF per year for plug loads. This results in a regulated EUI, as defined by EPAct 2005, of 20 kbtu/GSF per year. When kitchen equipment process loads are subtracted from the design EUI, the project is anticipated to have an adjusted EUI, for the purposes of LBNL benchmarking, of 25 kbtu/GSF per year. Refer to Appendix A for the detailed concept design energy analysis outputs.

The following list outlines the projects compliance with and/or current status relative to the LBNL energy use reduction requirements and targets:

• 30 percent reduction from ASHRAE 90.1-2013, excluding process loads (DOE requirement): The Welcome Center is showing a reduction of 37.6 percent over ASHRAE 90.1-2013, excluding process loads. As of 50% Preliminary Design, the

37.6 percent reduction reflects the most cost-effective design solution, as determined by the Life Cycle Cost Analysis (LCCA) using the manufacturer recommend lifespans. This meets the Federal requirements for a minimum 30 percent energy use reduction from ASHRAE 90.1-2013.

• 30 percent reduction from ASHRAE 90.1-2013, including all end uses (LBNL requirement): The Welcome Center is currently showing an 18.7 percent reduction over ASHRAE 90.1-2013, including all end uses. The 30 percent requirement is unlikely to be met given that the kitchen equipment loads total almost 60 percent of the building’s energy use. The current model assumes that kitchen equipment process loads are equal in the baseline and proposed models, which reflects a 0 percent savings for the largest energy end use in the project.

The 30 percent savings may be attainable if an Exceptional Calculation Methodology is recognized during Final Design to demonstrate a quantifiable reduction in kitchen equipment energy use.

• 50 percent reduction from the LBNL benchmark building (LBNL target): The Welcome Center has a predicted EUI of 63 kbtu/GSF per year, which is a 34 percent reduction from the LBNL benchmark. The predicted EUI is 31 percent over the target EUI of 48 kbtu/GSF per year, which is only attainable if a significant reduction in kitchen equipment process loads are realized during Final Design. The 65 percent stretch target reduction is not possible given that the energy use associated with the kitchen equipment alone exceeds the stretch target.

• 50 percent reduction from the adjusted LBNL benchmark building (LBNL adjusted target): The Welcome Center has an adjusted EUI of 25 kbtu/GSF per year, which is a 68 percent reduction from the adjusted LBNL benchmark. The adjusted EUI meets both the 50 percent reduction target and the 65 percent reduction stretch target established by LBNL.

• Percent reduction from ASHRAE 90.1-2010 (LEED requirement): The Welcome Center is currently showing a 22.8 percent reduction over ASHRAE 90.1-2010, including all end uses, as prescribed by the LEED v4 Rating System. LEED requires that all process uses, including equipment and receptacle loads, be modeled as equal in the baseline and proposed cases. The project may see further improvement once the kitchen equipment is confirmed and optimized during Preliminary and Final Design.

The following design process is used to reduce energy use and design towards LBNL’s energy use reduction targets:

Address the energy loads placed on the Building by using proper Building orientation and utilizing passive design measures. The project is implementing design strategies that will take advantage of the mild Berkeley climate and minimize the use of refrigerant based cooling. Measures include mixed mode natural ventilation, daylighting, glare control, ceiling fans, economizer mode in non-naturally ventilated spaces and optimal envelope design. Refer to the Architectural, Mechanical and Electrical BODs for additional information.

Utilize efficient Building systems to meet the lighting and HVAC requirements. The project is targeting a very low lighting power density and is proposing to use efficient HVAC systems that are specific to each program space type. Refer to the Mechanical and Electrical BODs for additional information.

Use renewable energy systems to supply the Building’s energy demand. The project provides a solar ready area that allows for the largest, simplest, and most cost-effective PV system, while also maintaining daylight access to the cafeteria and servery spaces.

At a minimum, the solar ready area will supply at least 7.5 percent of the building’s anticipated energy use with renewable energy. The concept design includes a solar ready area totaling approximately 7,816 GSF. Three separate PV panel options were assessed to determine the amount of energy that may be generated with this area:

• A 0-degree tilt system offers the most generation per square foot of roof area;

however, it is the least efficient system per panel and results in the longest return on investment (ROI) period.

• A 20-degree tilt system is sized to accommodate a 3 foot walkway between the panels, which offers a good balance between performance, ROI and maintainability:

• A 30-degree tilt system is considered the optimal system with the most generation per panel and the shortest ROI period; however, it results in the lowest overall system generation because fewer panels will fit within the designated solar area

With a predicted EUI of 63 kbtu/GSF per year, the Welcome Center will require a minimum renewable production intensity (RPI) of 5.0 kbtu/GSF per year. The PV calculations indicate that any of the PV array options within the solar ready area are sufficient to meet the minimum RPI required to generate 7.5% of the project’s energy use. To meet the project’s renewable goal to provide the largest, cost-effective PV array on the roof, the 20-degree tilt option is the current basis of design for cost purposes, as it offers greater production with a minimal 1 percent increase in the ROI period.

Use sustainable operations and maintenance practices. The Welcome Center will include a detailed performance monitoring program that will measure individual end uses and allow LBNL to understand exactly how the facility is performing. Metering and metrics will be defined according to the Berkeley Lab Sustainability Standards for New Construction. During Final Design, metering and metrics across all building disciplines (HVAC, lighting, electrical, plumbing) will be detailed on a common set of plan pages indicating meter integration and applicable specification sections. Refer to the Mechanical and Electrical BODs for additional information.

Materials and Resources

• The project will be a zero waste facility. The current zero waste target is to accommodate a waste reduction of >90 percent. Composting and recycling will be provided throughout the facility and will be visible and easily accessible to occupants.

The waste bins at the loading dock are sized according to current LBNL data, with compactors being considered for each waste stream to increase the volume of waste that each of the bins can accommodate. A cardboard baler is also proposed to improve the operational efficiency of the materials management and to reduce the space required to store and recycle cardboard. The conceptual flow of waste materials throughout the Welcome Center is outlined in the Waste Flow Diagram, which will be updated during preliminary design. The Plan was reviewed with LBNL to confirm that it aligns with their operating procedures and goals.

• A small-scale anaerobic digester is being considered for the management of food waste. The digester will be located at the loading dock, if provided by LBNL. The digester is not currently in the scope of the project.

• The cafeteria will not use disposable dishware or cutlery. All dishware and cutlery used within the facility will be washed and reused for future servings. Take-out dishware is planned to be reusable, with a return station location to be determined.

• Specifications will require the contractor to implement a construction waste management plan that results in an end of project diversion rate of at least 80 percent. A higher diversion rate shall be pursued.

• Dedicated Waste Management Rooms at levels 1 and 2 – associated principally with with Conferencing and Operations on Level 1, and Food Service spaces on Level 2– provide access to waste chutes that deposit at the waste collection area at Level 0.

The Kitchen at level 2 will include space for a scale to weigh the amount of food waste generated during food production at the facility. The preliminary design documents indicate three chutes: trash, compositing, and recycling. Refer to the 50% Preliminary Design plans for additional information and locations.

Occupant Well-Being

• The cafeteria will provide occupants with substantial access to daylight, views, and outdoor air. The conference center will provide occupants with access to views. The Operations department will provide occupants with access to daylight. The Health Services department will provide staff with access to daylight and views. Daylighting will be provided using a central skylight and through sidelighting strategies.
