Preliminary LEED Score Sheet 
 
Based on preliminary assumptions about building systems and materials, it is estimated 
that this project can score between 49 and 63 points on the LEED Score sheet.  The 
objective is to achieve a minimum of LEED Silver (50 – 59 points).  As part of our 
Schematic Design phase, we will host a LEED charrette with our engineering consultants, 
representatives from the City, and the Alameda County Stop Waste program to discuss 
and recommend achievable goals for a sustainable, energy efficient design.  Community 
education on sustainability will be an important component of our approach.

Preliminary Cost Estimates 
 
In order to discuss and compare the two proposed design approaches, we asked our 
construction cost estimator, Alice Nguyen of Davis Langdon, to prepare initial cost 
summaries for schemes B2 and C, based on the drawings and models presented at the 
second community meeting.  Because these are based solely on concept sketches, the 
pricing is very preliminary.  However, the comparison did illustrate that the addition of a 
second floor to accommodate the full program in scheme B2 resulted in an increase of 
approximately 10% in the anticipated construction cost.  This is due to the added scope 
for elevators, stairs, duplicated restroom facilities, and some inefficiency in locating the 
children’s room in the existing main reading room.  Overall, the costs associated with 
the proposed scope of renovation required at the existing library building were roughly 
equivalent to the cost of new construction at the site. 
 
The conceptual estimate summaries are attached, but should be used for comparative 
purposes only, since they are not yet based on actual design schemes.  Davis Langdon 
will prepare a more detailed and thorough estimate at the end of the schematic design 
phase, with updates at the end of design development, and at the midpoint and 
conclusion of construction documents. 
 
Based upon these initial estimate studies, we anticipate that the project can be 
successfully funded based upon the proposed construction budget of $4.3 million. 
 
The component cost summaries for schemes B2 and C follow.

Planning and Zoning Issues 
 
Site Coverage  
 
The site is zoned R2‐A, which allows for a maximum FAR of 50%.  The total lot area is 
13,398 sf, resulting in an allowable maximum building area of 6,700 sf.  Our proposed 
building, with a footprint of approximately 8,200 square feet has an FAR of 61%.  We 
will need to apply for a variance for this larger building site coverage. 
 
Building Setbacks 
 
                                Existing               Required         Proposed 
         Front                  19’‐9”         15’‐0”           7’‐0” (to 22’‐0”) 
         Street Side            7’‐6”          7’‐6”            5’‐0” (to 36’‐0”) 
         Side                   15’‐0”         4’‐0”            5’‐0” 
         Rear                   4’‐5”          15’‐0”           8’‐0” 
 
A variance will be required to allow us to reduce the required setbacks on 2‐3 sides of 
the building, depending on the final design footprint. 
 
Building Height 
 
Current zoning for the site allows for a maximum building height of 28 feet.  Our 
proposed building is a one story structure with an approximate maximum height of 24 
feet.  This is lower than allowed, and lower than most of the other buildings on the 
block, including the adjacent property owned by the Buddhist temple. 
 
Parking 
 
The existing South Branch Library does provide on‐site parking for 2 cars associated with 
the Tool Lending Library (TLL).  The proposed new building will also provide 2 designated 
spaces for the TLL, with one of them van accessible.  We also propose to have select 
curb areas along Martin Luther King and Russell Street striped green for short term 
parking only.   Because the site is readily accessible by foot, bicycle, and public transit, 
initial review with the Transportation Department suggests that no additional on‐site 
parking would be necessary. 
 
The Berkeley Public Library has a policy of not providing on‐site parking for staff, and 
this policy will not change.

Conclusion and Next Steps 
 
Based upon the unanimous vote of BOLT, as well as feedback from library staff, the 
preferred design direction is option 2 – demolition of the existing library building and 
construction of a new building.  This also represents the feelings of the majority of the 
community members who participated in the three meetings held during this phase. 
 
In accordance with the initial historical assessment, the library is preparing to submit a 
focused Environmental Impact Report.  We will confirm if there are any impacts other 
than the demolition of the new building.  The goal is to structure an efficient and timely 
review process, so as not to add undue cost or delays to the project. 
  
We will commenced our schematic design, based on Kathy Page’s updated building 
program and the preferred direction from BOLT.  We will also continue to meet with 
planning staff and the Landmarks Preservation Commission to pursue the demolition of 
the existing library building, and will file variance requests with planning to allow for our 
proposed site coverage, setbacks, and on‐site parking.  These discussions are ongoing. 
 
We will meet with City and County staff, and our full consultant team, to review and 
update the sustainability goals for the project, with the intention of submitting for LEED 
Silver certification for the new library. 
 
One additional community meeting is planned for the schematic design phase, at which 
we will present our updated design, and discuss the proposed architectural character 
for the new library and the landscape areas around the building.  We will continue to 
meet regularly with library staff and Kitchell, the construction manager for the four 
branch library projects during this next phase.

 There is inadequate space on the site to otherwise
 accommodate these requirements. This variance will
 involve building to the line of the existing north wall
 of the current building, maintaining the same visual
 appearance of the rear wall of the library from the north
 compared to the present building.

 The new building design incorporates the following
 principal design features:

     • Large roof area with relatively large height on
       the south elevation. While this approach permits
       adequate space with enough clearance from
       shadows from neighboring buildings for the required
       solar photovoltaic system array, it also creates a
       significant architectural presence on University
       Avenue.

     • The large internal volume with the large daylight roof
       monitors are reminiscent of the industrial warehouse
       buildings that are part of the history of West
       Berkeley, formerly known as Ocean View.

 7. ZERO NET ENERGY DESIGN

 One of the principal goals of the West Branch Library
 project is to achieve a design that uses no net energy
 over the course of a typical year for heating, cooling and
 electricity. Success with this design goal means that the
 West Branch Library would be the first known zero net
 energy library in the United States.

 To achieve this, the design team is first of all developing
 design strategies to minimize the energy load on the
 building for the thermal environment,the lighting and
 electrical equipment. If the load is reduced to about
 40% of the load prescribed by California Title-24 for a
 comparable building, then it will be feasible to install a
 solar photovoltaic system on the roof of the building to
 supply sufficient renewable energy to offset the total
 energy load over the course of a year. See Figure 9 for
 an example of this approach to the building’s energy use
 and renewable energy supply.

 The building will paricipate in PG&E’s solar electric
 program. When there is an abundance of solar energy
 available from the PV system, the building will export
 energy into the electric grid, getting credit from PG&E.
 When there is inadequate solar energy available, such
 as during dark winter days, then the building will draw
 on the PG&E electric grid for its needs. With the zero net
 energy design of the building, the net balance at the end
 of a typical weather year will just balance to zero and the
 library’s net energy bill for the year will be zero.

 A detailed report on the zero net energy design for the
 West Branch Library is being issued under separate
 cover.

1. Introduction

   The existing West Berkeley Branch Library is planned to be replaced with a new
   building. Due to its location on the busy arterial of University Avenue in Berkeley,
   CA, noise intrusion into the library is a significant issue. A noise study was
   performed to document the existing noise on the site and to provide an
   assessment of the mitigation that would be necessary to achieve appropriate noise
   levels within the new facility.

2. Environmental Noise Fundamentals

   Noise can be defined as unwanted sound. It is commonly measured with an
   instrument called a sound level meter. The sound level meter captures the sound
   with a microphone and converts it into a number called a sound level. Sound
   levels are expressed in units of decibels. To correlate the microphone signal to a
   level that corresponds to the way humans perceive noise, the A-weighting filter is
   used. A-weighting de-emphasizes low-frequency and very high-frequency sound
   in a manner similar to human hearing. The use of A-weighting is required by most
   local General Plans as well as federal and state noise regulations (e.g. Caltrans,
   EPA, OSHA and HUD). The abbreviation dBA is sometimes used when the
   A-weighted sound level is reported.

   Because of the time-varying nature of environmental sound, there are many
   descriptors that are used to quantify the sound level. Although one individual
   descriptor alone does not fully describe a particular noise environment, taken
   together, they can more accurately represent the noise environment. The
   maximum instantaneous noise level (Lmax) and the noise level exceeded 10
   percent of the time, or L10, is often used to identify and characterize the loudness
   of a single event such as a car passby or airplane flyover. To express the average
   noise level the Leq (equivalent noise level) is used. The Leq can be measured over
   any length of time but is typically reported for periods of 15 minutes to 1 hour.

   In environmental noise, a change in noise level of 3 dB is considered a just
   noticeable difference. A 5 dB change is clearly noticeable, but not dramatic. A
   10 dB change is perceived as a halving or doubling in loudness.

3. Noise Criteria

   The typical function of a library is to provide an environment that individual users
   can focus on reading in the absence of excessive noise and distracting
   conversation. Additionally, libraries are often a space used occasionally for formal
   or informal group functions that may involve reading or speaking/presentations. It
   is the latter use that may pose the more stringent acoustical criteria for the space
   since “speech intelligibility” by listeners is generally affected more by excess noise.
   An environment for reading is less impacted by higher ambient noise levels as long
   as “single event” noise is not too excessive.
                                           Attachment 7 - Appendix to Admin Record

   For an overall criterion for occupied spaces, we frequently turn to American
   Society of Heating, Refrigerating and Air-conditioning Engineers (ASHRAE) for
   guidance. The focus for ASHRAE is on steady-state noise generated by
   ventilation and air-conditioning equipment. However, their criteria can be a useful
   guide for qualifying non-HVAC equipment noise intrusion, such as steady traffic
   noise. As published in their long-standing ASHRAE Handbooks, the
   recommended Noise Criteria (NC) is 30 to 40 which roughly translates to an A-
   weighted noise level range of 40 to 50 dBA.

   However, more recent studies of spaces used for education and persons with
   hearing or speech challenges, suggest that more stringent acoustic criteria is
   appropriate. For instance, the Collaborative for High Performance Schools
   (CHPS) as well as LEED® for Schools mandate a maximum ambient noise level of
   45 dBA in all core learning spaces, which typically include libraries. Additionally,
   CHPS offers additional “points” for reduced ambient noise level at thresholds of 40
   and 35 dBA. Lastly, in our recent work with classrooms and children with hearing
   impairment, advocacy groups such as the American Speech-Language-Hearing
   Association (ASHA) suggest criteria found in the recent American Nation
   Standards Institute (ANSI) standard S12.60-2002, Acoustical Performance Criteria,
   Design Requirements, and Guidelines For Schools, of 35 dBA for typical
   classrooms and 40 dBA for large classrooms. Additionally, ANSI has criteria for
   “single event” traffic noise whereby the average noise-level exceeded 10% of the
   time is 40 dBA for a typical classroom and 45 dBA in a large classroom.

   The goal for these various criteria is to maintain good to excellent speech
   intelligibility and focus within the occupied space. In areas where speech
   intelligibility is not important, the criteria can be slighted relaxed.

   Therefore, our recommended criteria for various types of spaces are as follows:

4. Existing Noise Environment

   Noise measurements were conducted from between December 17th to the 21st.
   The locations of the outdoor measurements are shown on Figure 1. A “long-term”
   noise monitor, Location A, measured noise levels for the full 5 days and was
   located at the western edge of the lower library roof closest to University Avenue.
   A “short-term” spot measurement was performed on the existing driveway at the
   southwest corner of the site and at the approximate setback of the new building. A
   plot of the measurement results is shown on Figure 2.

   The noise levels that are expected to impinge upon the new facility are shown on
   Table 2. Consideration was made to not include noises generated by the ongoing
   construction occurring across University Avenue and for time periods when the
   library would normally be closed (8PM to 10AM).

                  Table 2: Summary of Noise Measurements Outdoors

                                                        Leq dBA
    Façade facing University Avenue (5’
                                               69          70           69        75

    sidewalk)

   Analysis of the summary data suggests that the primary factors to consider is the
   loudest hourly average noise level Leq of 70 and 68 dBA and the average Lmax as
   occurring within 15 minute periods of 75 and 72 dBA. While we had documented a
   few noise Lmax events in excess of 90 dBA, we feel that the few occurrences over
   the 5 days did not warrant to be included in the design factor for this project type.

   A short term noise measurement was also conducted in the existing library.
   Exposure to University Avenue noise is limited to south facing windows that are
   set-back about 20’ from the side walk and significantly shielded by a wood fence
   and buildings that extend past the windows and to west facing windows set-back
   40’ from the sidewalk. The current noise in the library appears to be dominated
   from the ventilation system and office equipment/computers as well as from activity
   of the patrons and staff. The louder noises on University Avenue are, however,
   audible in the Library.

   Figure 3 depicts the sound-spectrum of the traffic noise impinging upon the library.
   This information is necessary for determining the noise reduction requirements of
   the building elements that will comprise the south façade of the new library. For
   instance, when selecting the glazing system, the noise reduction performance at
   125 Hz and 160 Hz must be adequate to resist the low-frequency (rumble)
   component of the traffic noise spectrum.

5. Analysis

                                      Conceptually, the “shell” of the building within the first 15-feet from the sidewalk
                                      must provide a noise reduction of roughly 35 decibels (dB) in order to achieve our
                                      recommended noise criteria. A typical exterior grade, stucco wall provides at least
                                      45 dB, while a typical 1-inch insulating glazing unit provides about 30 dB noise
                                      reduction. Additionally, any door along the south façade will provide little to no
                                      noise reduction when opened, which can not be avoided when the library is open.
                                      Passive ventilation through open windows or simple louvers near the south façade
                                      offer little to no noise reduction performance. Therefore, the design must include
                                      noise reduction upgrades and features at the windows, doors and ventilation to the
                                      outdoors.

                                      Several of the proposed schemes that we have seen have facades that are within
                                      5-feet of the sidewalk and comprised of all glass exterior walls at the main reading
                                      room. The implication of this design concept is that the glazing alone will be
                                      responsible for the majority of noise reduction to the spaces immediately on the
                                      interior. Additionally, most of the proposed schemes also have the entrance facing
                                      University Avenue. This poses a particular challenge since typical exterior
                                      entrance doors do not have a high degree of inherent noise reduction capability
                                      due mainly to the difficulty in providing effective gasketing around the perimeter of
                                      the doors. Lastly, the concept of “natural” ventilation precludes having operable

   windows along the south and most of the east and west facades. Any air
   passages to and from the outdoors must be acoustically treated to reduce the
   transfer of outdoor noise into the occupied spaces.

6. Design Concepts

   At this stage of the design, we present the basic concepts to be considered for
   achieving our recommended noise criteria. As the design progresses, we are
   available to help further refine the noise reduction treatments and upgrades.

   6.1. Windows

        Windows facing University Avenue should have a minimum STC rating of 40
        and an octave band noise reduction (NR) at the lower frequencies of 125 and
        160 Hz of at least 30 dB. If the window area were to be significantly reduced
        from 100% to 50%, then the STC ratings and NR could be reduced by about 3
        points.

        A “typical” one-inch insulating/laminated (¼” laminated, ½” air-space, ¼”
        laminated) window has an STC rating of around 40 but would result in an
        average and single event noise level that would exceed our recommended
        criteria. However, when taking the 125 and 160 Hz octave band performance
        into consideration, the required window would still be an insulating/laminated
        window but would need to have a 2-inch airspace rather than ½” in order to
        adequately reduce the lower frequency noise, typical of a truck passby or noisy
        motorcycle.

        At 2nd story windows that are setback from the sidewalk, typical one-inch
        insulating/laminated windows would be adequate for meeting rooms or offices
        with large windows facing south.

        At skylights and windows facing north, standard insulating glass should be
        adequate.

        As window to wall ratios decrease, the STC/NR requirements of the windows
        also decrease. Therefore, as the fenestration design begins to develop, we
        are available to perform refined analysis for STC and NR requirements.

   6.2. Entrance Doors

        Two sets of doors separated by an acoustically treated vestibule will be
        necessary to adequately attenuate intrusive noise from University Avenue.
        Conceptually, it would be optimal for the 2 sets of doors to be organized so
        that when one door is open, the other is closed. With both doors open at the
        same time, the noise reduction through the entrance will rely solely upon the
        acoustic treatment in the vestibule, which is limited to about 20 to 25 dB.
                                           Attachment 7 - Appendix to Admin Record
West Berkeley Branch Library, Berkeley, CA Page 967 of 2455                Page 8 of 8
Environmental Noise Report                                                         27 January 2010

        We understand that automatic sliding doors can inherently open and close in a
        shorter time than swinging doors. If this is the case, then we recommend
        sliding doors to minimize the chance for both doors being open at the same
        time.

        Features that will offer increased noise reduction through the vestibule include,
        increased distance between doors, a “dog-leg” in the vestibule, a lowered
        ceiling that is acoustical absorptive (1-inch thick fiberglass panels or lay-in tile)
        and acoustic panels on all available wall surfaces (tack-able 1-inch thick fabric
        wrapped fiberglass panels). An all glass vestibule with a hard-finished floor is
        not ideal and should be avoided.

   6.3. Passive Ventilation

        The typical scheme for achieving air transfer between noisy spaces is via
        acoustically lined ductwork or building chases. The length and configuration of
        the duct or chase would depend open the location of the outdoor opening
        relative to University Avenue and the cross-sectional area of the opening.
        Very roughly, a duct lined with 1-inch thick fiberglass duct-liner could achieve 1
        dB/foot reduction for a large duct (10 square feet) to about 5 dB/foot reduction
        for a small duct (1-foot square). Additional reduction can be achieved with 90-
        degree elbows, 2-inch thick lining and special “duct-silencers”, as necessary.
        Also, square shapes tend to provide better reduction than circular shaped
        ducts.

        Noise generated by associated HVAC system should also be reviewed and
        designed to achieve our recommended noise criteria within the various
        occupied spaces.

to the three held during the earlier Concept phase. The final meeting for each phase was 
a formal presentation to BOLT. In addition, the design team met with library staff, 
planning and building department staff, the city arborist, and the full Landmarks 
Preservation Commission. The meetings are outlined in the process section which 
follows. 
 
Based on the BOLT direction at the end of the concept design phase, we have 
proceeded to study an all new library, to be built at the site of the existing building at 
the corner of Russell Street and Martin Luther King Boulevard.  
 
Based on our meetings with planning department staff, we now know that a focused 
environmental impact report is planned for the project. The schematic drawings 
included in this report should be sufficient for inclusion in that study. 
 
In addition to the updated Library Program and Schematic Design documents, this 
report includes our updated LEED spreadsheet, which has been refined with input from 
our engineering consultants and the City’s green building coordinator. A second LEED 
charrette was held on February 22, with the representatives from KEMA, the 
sustainability consultant retained to help with the projects by Alameda County Stop 
Waste. It also includes the draft schematic cost estimate.

Building Program 
 
 
The space program for the South Branch Library and Tool Lending Library was generated 
by library planning consultant Kathy Page, incorporating input from her meetings with 
Library staff. The final schematic design phase program calls for a total gross building 
area of approximately 8,000 square feet. This yields a net assignable area of 
approximately 6,000 square feet.  The existing structure measures approximately 5,400 
gross square feet. Code mandated increases to restrooms and program areas for 
accessibility would require about 6,900 square feet to provide the same level of use.  
 
Based on our discussions with library staff, we agreed to modify the program in a few 
areas. We added a small group study room of approximately 100 sf, and reduced the 
area of the multi‐purpose room to approximately 750 sf. 
 
The chart on the following page summarizes the January 28, 2010 updated program 
which was received from Kathy Page. Areas not given in the chart, including lobby and 
restrooms, are included in the net to gross area mark‐up that is added in at the bottom 
of the table. This “grossing” factor also includes mechanical and electrical closets, 
plumbing shafts, and wall thicknesses. 
 
Please note that the actual areas are slightly different from what is called out in the 
program, but we have worked to assure that the proper number of seats, computers, 
and lineal feet of shelving are all included. The actual gross area of the building is 
currently closer to 8,250 gsf. 
 
Refinements will continue to be made during design development as we modify the plan 
in response to mechanical and electrical system requirements documented during 
schematic design.  
 
The following chart compares the new program square footages to the existing building:

Schematic Design Alternatives 
 
Based on the concept design input from library staff, the community and BOLT, we 
proceeded to study design alternatives for an all new building for the existing library 
site. While we retained the basic plan configuration for the new scheme, we explored a 
series of massing options. 
 
We facilitated the fourth community workshop on January 27, 2010 and presented two 
alternative design schemes – Option A and Option B. We received very positive input 
from the community members who participated. [Unfortunately, it was the same night 
as the President’s State of the Union Address, so participation was limited.] 
 
Following on pages 8 through 15 are the presentation drawings, photos of the massing 
models, and image boards presented at the January 27th workshop. Full minutes from 
the meeting are available from Suzanne Olawski at the library. 
         
         
         
Preferred Design Alternative 
         
On February 2, 2010, we met at the South Branch with library staff whose comments 
resulted in several recommendations which were implemented; among them: to shift 
the library desk to have greater visibility; to flip the community room and toilet 
room/storage locations; to provide a more private staff work area for the Tool Lending 
Library. 
 
Based upon the input from the community, the library staff, and the library 
administrative team, we proceeded to develop a preferred schematic design approach 
for the building massing and exterior character. The final design was presented to BOLT 
on February 10th, 2010 and received enthusiastic response for the design direction. Field 
Paoli was directed to proceed with the design development phase of work. 
         
Following on pages 16 through 19 are the presentation drawings and the photos of 
massing models presented at the BOLT meeting. Minutes from the meeting are available 
from the library website:

Schematic Design Documents 
 
The following sheets (pages 21‐30) are reduced copies of all of the documents in our 
schematic design drawing set. Full or half size copies of these will be issued to the library 
for actual review, as these will be too small to read clearly. 
 
The drawings are followed by the outline specifications in full (pages 30‐70).
