ENERGY MASTER PLANNING
Energy Master Planning: a holistic, comprehensive planning methodology for a building’s current and future energy needs (instead of a one-off approach to fixing inefficient or broken systems).
► Proactively address and reduce your energy costs
► Generate reliable and predictable savings over time
► Reinvest savings into the implementation of additional energy conservation
measures and renewable energy installations, and meet future energy demands
► Address deferred maintenance
► Improve the safety, comfort, and health of the environment
► Reduce greenhouse gas emissions
► Increase reliability and resiliency
The VALUE PROPOSITION
► An Energy Master Plan is created by:
► Evaluating a facility’s current energy uses, consumption, actual energy needs,
and future energy needs.
► Identifying inefficiencies.
► Providing solutions to achieve conservation goals (demand-side) and
generation goals (energy assets) that provide greater value based on a
feasible and realistic return on investment.
How Energy Master Planning Works
THE PROCESS
Performance goals drive energy management activities and promote continuous improvement. Goals may be shaped by:
► Internal rates of return; Internal planning horizons and guidelines; Organizational strategic plans
► Commitments to voluntary environmental initiatives► Resiliency goals• How can solar PV/energy storage/microgrid technology help you to be less
reliant on the centralized power grid if it were to go down following a natural disaster or grid failure?
STEP 1 | SET GOALS
Baseline Assessment: Annual energy consumption is analyzed by gathering data from utility bills, energy management systems, audits, infrastructure reports, and renewables potential studies. • Helps to identify factors that affect energy performance. It informs where
energy investments should go, and provides a reference point for the performance of a facility’s energy investments.
California Benchmarking Requirement: AB802 requires that energy is disclosed to the State for all commercial buildings over 50,000 square feet (or multiple buildings that are 50,000 sq. ft. in aggregate, served by one meter)
STEP 2 | Analyze Energy Data
► Combine demand-side with supply-side into one comprehensive strategy► Integrate it with your goals for return on investment, greenhouse gas
emissions reductions, and resiliency.► Develop a long-term strategic plan
STEP 3 | Identify Potential Opportunities
► An implementation plan will answer: • How are the organization’s goals and targets being addressed? What are
the costs? How will the projects be funded? What are the project delivery methods? Who will develop designs? What is the schedule for completion?
► Identify resources and leverage innovative financing, such as • On-bill financing; Shared savings models; Low and zero interest loans• Power Purchase Agreements (PPA); Asset leasing; Shared savings
models; Behind the meter revenue streams
STEP 4 | Create an Implementation Plan
STEP 5 | Monitor, Measure & Evaluate Progress
► The key tasks of monitoring, measuring, and evaluation let you know whether your projects are achieving your most important goals—and offer insights to address any shortcomings.
ACTION ITEMSTo start the process of effective energy
management, consider the following 5 action items
Action Items (1 of 5)
1. Schedule an Energy Planning Meeting with your Facilities/M&O/ Energy Manager. Start the conversation by discussing:
a) What energy maintenance tasks take up the largest percentage of staff resources and time?
b) Do sites experience high energy usage spikes that could be reduced by the installation of battery storage systems?
Action Items (2 of 5)
2. Is there a Community Choice Aggregation Agency (CCA) currently serving your area or else being formed in your area? If so, approach the CCA to proactively ask what the CCA can do for you. For instance, if you have a battery storage project or are looking into pursuing one, ask the CCA how you can position yourself to partner with them to get additional revenues from those assets.
Action Items (3 of 5)
3. Find out what your electricity bill will look like when the Time Of Use shift occurs.
Action Items (4 of 5)
4. Have you benchmarked your facilities? Benchmarking will help you to identify where energy investments should go, and will help you to track the performance of those investments.
Action Items (5 of 5)
5. If you have a solar project (or are in the process of developing a solar project), ask your Facilities/M&O/Energy Manager to fill out this online Energy Asset Management Scorecard, and then discuss any needed actions: https://terraverde.energy/scorecards/

Energy Master Planning – Internal Meeting Planning Agenda
Attendees: Facilities Manager, Maintenance and Operations Director, Energy Manager, Sustainability Lead, etc.
Meeting Intention: To start a discussion about the organization’s current and future energy needs, and its opportunities for energy performance improvements.
Pre-Meeting Prep Work:
[Try to complete as many prep tasks as possible before hosting the Energy Planning meeting]
� Think about the performance goals that drive your organization’s energy management activities and promote continuous improvement. Energy Master Planning goals may be shaped by: Internal rates of return, internal planning horizons and guidelines, organizational strategic plans, commitments to voluntary environmental initiatives, and resiliency goals
� Prepare an analysis of energy consumption and energy use intensity per building site to better understand the load and usage patterns. This is done by calculating the annual energy costs and usage (including electric and gas) per square foot per building. *
� Prioritize buildings per high energy usage and prioritize within each building high use areas that could benefit from retrofits or replacements.
� Identify what the key barriers might be to having new energy projects approved.
Meeting Topics to Address:
PROJECT PLANNING
� What energy-related maintenance tasks take up the largest percentage of resources and time (such as repairing and/or programming HVAC, replacing lamps, electrical issues, etc.)?
� Is the headcount of the organization growing? � Are there any upcoming building renovation plans that should be coordinated with energy efficiency
projects? � Does the organization have a resiliency plan? What happens if the grid goes out for prolonged period? � Does the organization have the internal resources to self-procure and self-install energy efficiency
measures, or are the services of a General Contractor preferred to oversee the installation of energy efficiency measures? Does the organization have the resources to oversee project planning, vendor selection, project installation, and energy savings calculations? *

ENERGY EFFICIENCY Lighting Systems:
� Interior and Exterior lighting systems: Are there opportunities for improvement (such as improved lighting quality, reduced maintenance, reduced lifecycle costs, etc.) by replacing or retrofitting interior and/or exterior lighting systems?
� Interior and Exterior Lighting Controls: Are there opportunities to improve interior and/or exterior lighting controls by installing Title 24 compliant control mechanisms (such as timeclocks, astronomical clocks, photocells, occupancy sensors, daylight harvesting sensors, energy management system)?
Mechanical Systems & Kitchen Equipment: � What percentage of the HVAC and kitchen equipment older than 15 years? � Are any of the units in poor condition and require annual servicing and/or replacement? � When was the last preventative maintenance inspection completed? � Are there controls in place on the HVAC equipment (i.e. non-programmable thermostats, smart
thermostats, or proprietary EMS system)? � Is there a building energy management system in place at any of the buildings?
Roofing: � Do any of the buildings have known roofing issues? � Have any cool roofs been installed? If so when?
RENEWABLE ENERGY
� Are there parking lots, unobstructed roofs under 10 years of age, or open ground areas that could support the installation of solar photovoltaic (PV)?
� Do buildings experience high energy usage spikes, potentially resulting in significant “demand charges”? Has there been any consideration of battery storage as a means to reduce high demand charges*
� Do sites experience frequent power outages, brown-outs or grid unreliability? � Is there any existing onsite solar PV generation that is not being actively monitored by an independent
third party? If so, would those systems benefit from an asset management team ensuring the annual preventative maintenance and production guarantees are being met?
* In addressing this item, some Districts may benefit from engaging an independent energy consultant/advisor.
