I. Fairfax County Operational Energy Strategy and Sustainability Background

Fairfax County's commitment to environmental stewardship is demonstrated by policies, programs and projects that lower greenhouse gas emissions associated with its operations.

These efforts include reducing electricity and natural gas used in county buildings and operations, and gasoline and diesel used in county fleet vehicles and buses. Decreasing overall energy use not only provides wide-ranging environmental benefits, it also provides fiscal benefits to the county and its residents through utility cost avoidance.

On July 13, 2021, the Board of Supervisors adopted a new greenhouse gas emissions reduction goal through the Carbon Neutral Counties Declaration. Led by Fairfax County, Carbon Neutral Counties provides a mechanism for counties across the country to commit to operational emissions reductions. By signing the declaration, Fairfax County pledges to be energy carbon neutral by 2040, work with state and federal partners to advance this goal, and ensure it is implemented equitably.

Meeting this carbon neutral goal will require significant emissions reductions across all facets of county operations. As such, on July 13, 2021, the Board also adopted an update to the Fairfax County Operational Energy Strategy. First adopted in 2018, the Energy Strategy is intended to advance the objectives of the Board’s Environmental Vision through the setting of goals, targets, and actions across major focus areas. The updated Energy Strategy incorporates the carbon neutral goal in a new greenhouse gas emissions reductions focus area and includes accelerated targets across many of the remaining focus areas outlined below:

• Greenhouse Gas Emissions Reductions

• Energy Use and Efficiency

• Water Use and Efficiency

• Green Buildings

• Renewables

• Fleet Electrification

• Goods and Services

• Waste Management and Recycling

• Awareness and Engagement

• Utility Cost Management

• Reporting and Collaboration

In keeping with the Board of Supervisors requirements this project shall meet energy and sustainability requirements as set forth below.

D. ENERGY AND OTHER SUSTAINABILITY OPPORTUNITIES

Step 1

For every project design process performed for the Facilities Management Department the selected Firm provides details for each energy and/or sustainability opportunity available and recommended within the provided project. This is not a full study endeavor, however the Firm provides an overview for proposed energy and cost savings opportunities for each recommendation implemented in the provided design. For projects that move forward without

A/E stamped design it is the responsibility of the construction contractor to identify energy and sustainability opportunities that may or should be leveraged within the performance of the project work. For energy opportunities the contractor working with the equipment/material manufacturer should use the Fairfax County contracted utility rates to calculate cost savings.

Opportunities will be reviewed for acceptance by the FMD Project manager based on energy savings not just solely on ROI. At a minimum for each recommendation provide the following information:

• Details of baseline existing conditions and data collected

• Documentation of all assumptions and sources of data

• Details of engineering analysis performed

• How energy savings will be calculated

• Details of proposed energy and cost savings

• Details of post-installation verification activities, including inspections, measurements, analysis and customer project acceptance procedures

Projects may include but are not limited to:

• Lighting

• Metering

• BAS or other controls

• Roof

• Insulation

• Water conservation

• Solar

• HVAC

• Interior fit out (materials sustainability)

• Interior equipment sustainability (drinking fountains, flush valves, censored faucets, etc.)

• Exterior sustainability – vegetation and landscape management, pervious pavement

• Waste water diversion

• Other electrical efficiencies

• Retro-commissioning- HVAC

Define the Baseline Baseline physical conditions (such as equipment inventory and conditions, occupancy schedule, nameplate data, equipment operating schedules, key energy parameter measurements, current weather data, control strategies, etc.) are determined through surveys, inspections, spot measurements, and short-term metering activities. Utility bills may be used to verify that the baseline has been accurately defined depending on the method of verification selected.

Baseline conditions are established for the purpose of estimating savings by comparing the baseline energy use with the post-installation energy use. Baseline information is also used to account for any changes that may occur during the performance period, which may require baseline energy use adjustments. It is important to ensure that the baseline has been properly defined.

Documentation of assumptions is also critical for baseline development. After the Energy or

Sustainability project/equipment has been implemented, it is impossible to go back and reevaluate the baseline because it no longer exists. Therefore, it is very important to properly define and document the baseline conditions. Deciding what needs to be monitored (and for how long) depends on such factors as the complexity of the measure and the stability of the baseline, including the variability of equipment loads and operating hours, and the other variables that affect the load

Step 2

Conduct Post-Installation Verification Activities (primarily for HVAC, plumbing, and electrical equipment)

Once FMD has selected energy and sustainability opportunities to pursue the contractor will be asked to provide pricing to provide post-installation measurement and verification (M&V).

These activities will be conducted to ensure that proper equipment/systems were installed, are operating correctly, and have the potential to generate the predicted savings. Verification methods include surveys, inspections, spot measurements, and short-term metering. A post-installation M&V report is a key deliverable for energy and sustainability projects. The post-installation report at a minimum shall include the following.

• Project description

• Detailed list of installed equipment

• Details of any changes between the final proposal and as-built conditions, including any changes to the estimated energy savings

• Documentation of all post-installation verification activities and performance measurements conducted

• Performance verification—how performance criteria were met • Documentation of construction-period savings (if any)

• Status of rebates or incentives (if any)

• Expected savings for the first year. Example: “Building A” has three (3) Air Handling

Units that provide HVAC for the entire building. The units are at the end of their life expectancy and have become maintenance intensive just in the last several years. More importantly the housing for the units have failed to the point where air and water leaks have caused them to have operational issues and run inefficiently. In considering a proposed replacement for all of the units, awarded A/E Firm “X” has proposed new units be provided with low leak casings, and be equipped with direct drive fans in lieu of the existing belt driven fans. These changes/upgrades could expect the proposed, replacement units to use 10% less energy than predecessors.
