Firm’s Experience & References
SANDIA NATIONAL LABORATORY
Net Zero Roadmap and Critical
Loads Microgrid Design
Livermore, CA
For the first phase of the project, Interface Engineering
provided a conceptual framework and deployment timeline to
support Sandia National Laboratories efforts to improve the
sustainability and resiliency of their campus in Livermore. The
roadmap outlines requirements, identifies design solutions,
and provides an implementation plan for the California site.
The goal of the roadmap demonstrates a cost-effective means
to achieve Net Zero Green House Gas emissions and Net Zero
energy consumption by 2045. The roadmap also addresses
improving operational resilience with a renewable energy
microgrid, as well as opportunities for showcasing technology
developed through Sandia’s own research.
Interface provided a conceptual design for Sandia National
Laboratories to develop a microgrid with the primary goal
of resiliency. As a campus that conducts sensitive national
research, Sandia wanted to extend the backup power to
their existing critical loads to have 720 hours of backup
power. The existing critical loads were served by standby
diesel generators with a fraction of the fuel storage required.
Additional fuel storage was expensive, served no additional
economic benefit, and was against the campus’s long terms
goals of carbon reduction. Interface designed a renewable
energy microgrid composed of 11 MW of PV, 30 MWH of
batteries, and 2 MW of existing diesel generators that
provided renewable and sustainable backup power to the
campus’s critical loads.
The project required modeling expected load profiles for the
critical loads based on limited available historical meter data.
In addition to modeling the loads, Interface used HOMER
to model thousands of combinations of PV, battery, and
generator capacities to arrive at options that optimized for
various metrics, including lowest first cost, highest renewable
fraction, highest long-term payback, etc.
The project also required analysis and development of
multiple options to tie in the renewable assets into the
existing electrical infrastructure. These options included
local building microgrids that tied into each individual building
downstream of the building’s electrical service, parallel
distribution microgrids that tied into multiple buildings
downstream of the building’s electrical service, and fully
interconnected microgrids that tied into the campus’s
medium voltage system directly to serve the entire campus.
Interface also worked with a cost estimator to provide costs
for multiple options and went through a target value design
exercise to develop an option to meet Sandia’s budget.

meet tight design requirements without being oversized
or overusing energy that could otherwise be saved. The
HVAC system is 100% redundant for archive spaces.
Occupying the southeast corner of the parcel, the building
is compact and efficient, ceding a large portion of the site to
recreational and public use.
Interface Engineering worked closely with the County to
provide Mechanical Engineering and Energy Consulting for
the project, ensuring the project met its sustainability goals.
The project has been certified net zero energy by using a
140KW PV system (roof mounted and parking canopy) to
generate 10% more energy than it consumes on an annual
basis. The project also incorporates Level 2 EV charging
under the PV Canopy.
Interface conducted iterative energy simulations throughout
the design process, creating a highly accurate prediction
of all energy consuming systems within the project. The
facility’s NZE status is a significant achievement, especially
for an archive with high energy demands for temperature and
humidity control. Its success is attributed to careful design,
efficient systems, and on-site renewable energy generation.
Designed to harmonize with the surrounding landscape, the
ARCC facility acts as a backdrop to outdoor functions to
the north and a sweeping roof welcomes its visitors to the
entry plaza just off Mission Gorge Road. The archive and
all of its associated program components are located in the
northeast corner of the building, bound by the public reading
room on the west, and shaded by the primary building roof
from the south.
Conceptualized as a vault, the archives are enclosed within
highly insulated and tightly constructed concrete walls. Its
slab on grade will have a continuous vapor barrier, and the
walls will have a low permeability paint layer. The archive is
positioned to minimize environmental impacts to its critical
interior climate, making sure its contents are protected for
years to come.

Electric Vehicle Charging Facility
Sunnyvale, CA
As part of a SERA client’s ongoing commitment to
sustainability and decarbonization, a vacant site in
Sunnyvale, CA will be transformed into a state-of-the-art
Electric Vehicle (EV) charging facility. This project, led by
Stuart Colby and Spencer West, will convert the site into a
dedicated charging hub for the client’s electric shuttle fleet,
supporting their broader efforts to reduce carbon emissions.
The facility will feature a large solar photovoltaic (PV) canopy
that will generate clean, renewable energy for the fleet,
reducing reliance on grid power and aligning with the client’s
ambitious carbon-free energy goals. To further enhance
resilience and efficiency, the site will include on-site battery
storage, enabling energy capture and distribution during
peak demand periods. This project not only supports one
of the largest developers on the West Coast in achieving
their sustainability goals but also demonstrates innovative
approaches to electrified transportation and site resilience.CITY OF DIAMOND BAR – CIVIC CENTER SUSTAINABILITY STUDY | SERA2 | FIRM EXPERIENCE & REFERENCES11
Project Understanding
Project Understanding
We understand the inherent challenges and opportunities that come along with fleet
electrification and incorporating renewables and energy storage within existing sites.
We have identified some early concepts based on initial investigation of the site, and
we’re eager to get started.
However, we want to work with you to find the right solution that meets immediate
and long term needs. To do this, we will approach finding the right solutions by asking
questions and making sure project goals are clearly defined. The team we’ve built has
experience meeting the requirements of Executive Order N-79-20 and the California Air
Resources Board (CARB) Advanced Clean Fleets Regulation and working with clients to
achieve future goals for growth and advancing sustainability.
We also have an extensive history working with public and private clients, so we
understand how to engage multiple stakeholders to reach consensus on decision
making when there are often varying viewpoints using a “choosing by advantages”
framework. In this way, solutions take into account the multiple drivers that public clients
are required to navigate from the aspirational, like maximizing generation and planning
for growth, and functional drivers like long term maintenance and impacts of shading.
How We Get Started
We will organize our work into three distinct phases: Discovery, Analysis, and
Synthesis. Within these phases, we will tackle individual tasks where they can
inform the recommendations most effectively.
Working with your internal stakeholders, we will develop a shared set of desired
outcomes, document today’s starting point, and investigate multiple pathways for
improvement over time. By developing minimum, moderate, and aggressive (Good/
Better/Best) scenarios we can communicate key decision points the City will use to
refine and adjust its path toward its long-term goals.
At the start of the project, SERA will lead a collective pull-planning workshop,
collaborating with the City’s team and our partners to develop a week-by-week
schedule, strategizing an integrated approach for incremental progress. We will create a
predictable cadence of meetings, workshops, and decision points, adjusting as needed
if circumstances change.Preliminary Helioscope analysis of one parking lot section shows it can support a 190 kW PV canopy, producing ~290 MWh annually
(~18 kBtu/sf-yr renewable EUI), covering 25-35% of the building’s energy use.CITY OF DIAMOND BAR – CIVIC CENTER SUSTAINABILITY STUDY | SERA3 | PROJECT UNDERSTANDING12
Project Approach
Discovery: Align on Strategy,
Collect, Sort, & Distill
Confirm Facility’s Current Baseline
Performance, Articulate Facility’s
Desired Performance Targets.
SERA and Interface will begin by meeting
with the City’s project representatives to map
out how the facility is currently performing,
where there are known gaps, and the City’s
long term aspirations for the property.
Collect Existing Technical Information
(Meter and Building Management System
Data, As-Built Plans).
We will evaluate the energy-using systems—
lighting, heating, ventilation, air conditioning
(HVAC), building envelope, water heating,
electric vehicle charging, and other uses—
to develop an energy demand profile that
spans a calendar year. This will require
review of any trends available in the building
management system (BMS) and controls
and past utility bill data as well.
Meet With Key City Employees to Identify
Patterns and Fill Additional Data Gaps.
Often, data collection alone does not paint
the full picture. SERA and Interface will
likely seek to meet with facility management
personnel to understand how the building
has been operating; how the temporary
generator has been used over time; as well
as any known issues or challenges they
might identify with increased on-site energy
generation, storage, and vehicle charging.
Forecast of Future Electrical Demand.
this includes electrification of City Fleet,
additional on-site charging for public use,
and additional potential demand due to
expansion or other amenities.
The following tasks will completed during
the Discovery Phase: Task 1 – Electrical
Infrastructure Evaluation, Task 2 – Forecast of
Future Electrical Demand
Analysis: Investigate Possibilities,
Test & Plan for the Future
Summarize Findings of Existing
Conditions and Identify Upgrade Options.
After baseline understanding is complete,
we will produce a Draft Sustainability
Study with this basic structure: Existing
Conditions, Forecast of Future Electrical
Demand, and Opportunities and Constraints.
Develop an Integrated Site Plan: site
plan overlaid with pertinent infrastructure
information, electrical service capacity,
electrical system conditions, identified safety
or code compliance deficiencies, estimated
current electrical demand profiles broken
down by use type (interior lighting, exterior
lighting, HVAC, water heating, and plug loads).
Uncovering Opportunities and
Constraints: will utilize software including
Helioscope, HOMER, and IES-VE energy
modeling tools, our team will identify viable
Good/Better/Best targets for energy
reductions, on-site energy generation,
and battery storage, with the potential for
load shifting to reduce peak demands, and
other co-benefits as it relates to broader
sustainability and resilience (for example:
solar canopy coverage can reduce urban
heat island and used as a structure for
providing temporary shelter during disaster
events), known challenges and constraints
(such as easements, underground utilities,
tree shading, parking loss, accessibility,
power capacity limitations, etc.)
This draft report will form the basis for
the final Sustainability Study report
included as part of the Concept Plan
Deliverables. With buy-in from the City,
this will set the stage for actual concept
design activities.
The following tasks will completed during
the Analysis Phase: Task 3 – EV Charging
Infrastructure Planning, Task 4 – Sustainability
Enhancements, Task 5 – Infrastructure
Recommendations
Synthesis: Narrowing the Solutions
and Path Forward
We’ll kick off this last phase by presenting
design scenarios and optional services
to the City to generate buy-in and edit
final recommendations. This is also an
opportunity to discuss prioritization and
potential implementation over time. The
outcomes of this collaboration will inform
the final Conceptual Design Package.
The Design Team will leverage Good/
Better/Best targets for on-site generation
and storage to test site scenarios. For each
scenario, the team will evaluate its impact
across a range of key drivers (i.e. cost,
complexity, etc.) to support a final decision.
Incentive Mapping (Optional Task A).
SERA & Interface can coordinate with
Southern California Edison (SCE) and other
applicable incentive and grant programs
to identify funding opportunities, rebate
programs, and technical assistance
resources, leveraging previous experience.
Financial Planning & Phasing Strategy
(Optional Task B). Utilizing the site planning
scenarios and other potential sustainability
synergies, SERA and Interface can work
with a cost consultant and/or general
contractor to assign Rough Order of
Magnitude (ROM) costs for each scenario
and strategy, if desired.
Microgrid Design & Analysis (Optional
Task C). This optional task will include
conceptual analysis and sketches to
demonstrate what it would take to achieve
a full microgrid on-site, allowing the facility
to continue operations during extended
power outages (such as during Public
Safety Power Shutoffs).
The following tasks will completed during
the Synthesis Phase: Task 5 – Conceptual
Plan which includes the Sustainability Study
summarizing all findings, analyses, and
recommendations, including a Conceptual Site
Plan and supporting diagrams.
Additionally, the City can approve optional tasks
at this time for completion in this phase.CITY OF DIAMOND BAR – CIVIC CENTER SUSTAINABILITY STUDY | SERA3 | PROJECT UNDERSTANDING13
