2.0 Introduction

The Department of Veterans Affairs (VA) is required by the Energy and Independence Security Act of 2007 (EISA 2007) section 432 to conduct energy and water audits at each major facility once every 4 years. The energy and water audit are intended to provide a benchmark for the facility to use as a guide to improve energy and water efficiency. The audit should include an a review of all pertinent information from previous audits, retro-commissioning, SCIP submissions, and facility condition reports.

The facility energy and water audit should look at all of the following information:

· Building envelope (roof, windows, etc.)

· Heating, ventilation, and air conditioning equipment (HVAC)

· Building Automation Systems

· Metering – including identifying which buildings have submetering, considering IT integration

· Lighting systems and controls

· Operation and occupancy schedules

· Facility-specific equipment

· Renewable Energy systems, the possibility, true up old assessments

· Alternative energy systems other than renewables

· Water using equipment or processes such has kitchens, rest rooms, hot water, cooling towers, laundry and irrigation

· Water meters

· Maintenance items with an energy component

· Data Center – efficiency, etc. where relevant

· Retro-commissioning or ongoing commissioning

· Energy Star Portfolio Manager (https://portfoliomanager.energystar.gov/)

3.0 Method of Analysis

3.1 Analysis and General Description

A site investigation was conducted to document existing conditions to include campus layout, energy and water/sewer usage and building envelope description. The team reviewed all previous audits, retro-commissioning reports, SCIP submissions, and SCIP request for NRM funding. The following information is provided for each recommended ECM.

1) ECM description; should contain enough information to develop a statement of work (SOW).

2) Evaluation method;

3) Estimated cost to implement;

4) Estimated energy and/or water/sewer consumption savings – include Operations and Maintenance savings where possible;

5) Greenhouse gas (GHG) emissions savings;

6) Simple payback.

3.2 ECM Cost Calculation Description

Cost savings are calculated based on the actual historical energy costs for the facility. Installation costs include labor and equipment costs to estimate the full up-front investment required to implement a change. Costs are derived from RS Means Cost Data, industry publications, and local contractors and equipment suppliers. The evaluations are based on engineering estimations and industry standard calculation methods. Pricing information is based on budgetary equipment pricing and estimated labor costs. More detailed cost analyses require hard equipment specifications, and contractor bid pricing.

3.3 Energy Modeling Calculation Description

The ECM energy calculations and results are provided by excel calculations in the attached spreadsheet. Historical utility data is average for the three previous years (FY2018-2020) and is used to set the baseline utility information.

4.0 Historical Utility Consumption/Cost

4.1 Baseline Utility Usage Evaluation to Reduce Energy and Water Usage

Report documented energy and water usage at the facility.

The Environmental Protection Agency’s (EPA) Energy Star Portfolio Manager Program and VISN Service Support Center (VSSC) database record consumption and cost data for energy and water at each facility. Consumption data included energy and water commodity usage at the facility during the most recent three-year period

Example: Table below (data from VSSC)

Commodity Cost per Fiscal Year

As shown, electricity costs increased from FY 2018 to FY 2020. The electricity consumption increase was mainly due to the lack of ECM capital improvements to the facility. Fuel oil consumption was the driver for cost increased. Fuel oil increase consumption was due to the ongoing need to operate the generators. Natural gas costs per therm have reduced every fiscal year, while consumption has remained stable. Water costs increased by approximately 15.3% from FY 2018 to FY 2020. Water usage has increased proportionally within this timeframe; in 2020, the increase was largely caused by the opening of a new mental health facility as well as increased legionella water flushes. This correlates to the various construction improvement projects throughout this period. Sewer costs followed the same trend as the water usage.

In accordance with FAR part 41, a review of the utility bills has been conducted to ensure each meter and/or bill is on the appropriate tariff. The following utility rates and tariffs were verified. As a part of your review validate:

Electric Demand Charges on the bills to verify that it matches meter data.

Validate all accounts are on the correct tariff/schedule based on the account type and size.

Taxes and Fees should be reviewed. Most of the time we do not pay taxes and many fees do not apply Find ways to ensure you have the correct type of account for each your accounts.

Each facility should have an account representative at the utility ask for help to review your accounts.

Look for ways to conserve on the expense of utilities.

Do you need to add a water meter to your cooling towers to not pay sewer charges on your water?

Recommended Rates for Task 2 Study

4.2 Energy Review

A review of all energy project data and walk through of the facility should give you a holistic approach to what projects still need to be developed. Discuss the impact of completed projects. Discuss the potential impact of projects under development. This is where you will identify measures that will provide cost and savings. Also potential capital improvements that merit further analysis and provide initial judgements about project potential costs and savings.

· Building envelope (roof, windows, etc.)

· Heating, ventilation, and air conditioning equipment (HVAC)

· Building Automation Systems

· Metering – including identifying which buildings have submetering

· Lighting systems and controls

· Operation and occupancy schedules

· Facility-specific equipment

· Commissioning

4.3 Renewable Energy Review

Review feasibility studies for all sites (when available) and update assumptions as appropriate. Alternative renewable energy resources and technologies should include, but are not limited to, the following: geothermal energy (direct geothermal, ground source heat pump); solar energy (photovoltaic, solar thermal, solar concentrating); wind (turbines) include battery storage; also identify if there is a source of bio-fuel which can be used to fuel existing boilers, reciprocating engines, turbines and other applicable equipment; or methane from wastewater treatment plants or nearby landfills; include fuel cell, microturbine technologies and combined heat and power (CHP) system feasibility screening. If none of these are appropriate (cost, technical issues, etc.) it’s fine to write a short paragraph saying so, with some brief explanation.

CHP screening questions:

Answering "yes" to any of the following questions indicates that the facility may be a good candidate for CHP:

· Do you pay more than $0.10 per kWh on average for electricity (including generation, transmission, and distribution)?

· Are you concerned about the impact of current or future energy costs on your business?

· Is your facility located in a deregulated electricity market?

· safety, or health impacts if the electricity supply were interrupted?

· Does your facility operate for more than 5,000 hours per year?

· Do you have thermal loads throughout the year (such as steam, hot water, chilled water, or hot air)?

· Do you expect to replace, upgrade, or retrofit central plant equipment (such as generators, boilers, and chillers) within the next 3 to 5 years?

· Do you anticipate a facility expansion or new construction project within the next 3 to 5 years?

· Have you already implemented energy efficiency measures and still have high energy costs?

· Are you interested in reducing your facility's impact on the environment?

If you answer yes to any of the questions and have not had a feasibility study conducted, then use the CHP Screening tool on the EPA – CHP page. The excel tool is on the following link.

4.4 Water Review

When conducting the walk-through water survey verify at a minimum:

In the dining hall and kitchettes verify water using equipment such as dishwashers are energy star certified. The pre-rinse spray heads should be upgraded to allow for air assist. Ice machines use a lot of water, if air cooled then chances are it is energy star certified. If the ice machine’s serial number begins with an A then it is often energy star compliant. If not, then recommend upgrade or develop this into an ECM for future funding.

Cooling towers use an abundance of water so ensure there is a utility compliant water meter. This ensures that you are not being charged for sewer use.

Review your water meters are they in the correct place?

Are the meters reporting?

Hot water in rest rooms need to be compliant with the legionella directive and kept at the correct temperature.

Have the toilets, urinals, faucets and plumbing fixtures been upgraded to water sense certified products?

If your facility has a laundry, consider what you can do to improve water consumption - are the washers, dryers, and other relevant equipment energy star certified? Is appropriate metering in place?

Landscape irrigation should be monitored and measured. Irrigation systems that are controlled automatically based on weather and soil condition that precisely schedules the irrigation based on the actual needs of the plants are ideal. Consider what type of water is being used - Potable water, which is drinking water, Non-potable water that is not safe to drink, or alternative sources such as rainwater/gray/reuse water. Each state has its own rules.

4.5 Energy Star Rating

EPA, in an effort to promote energy management, created a system for benchmarking energy use among various end users, named Portfolio Manager. The Portfolio Manager tool allows tracking and assessment of energy consumption via the template forms located on the ENERGY STAR website (www.energystar.gov). Portfolio Manager will calculate a score for the facility on a scale of 1 to 100 based on user inputs. These ratings, on a scale of 1 to 100, provide a means for benchmarking the energy efficiency of specific facilities against the energy performance of similar facilities. The ratings are used by building and energy managers to evaluate the energy performance of existing buildings. Facilities that score a 75 or greater may qualify for an ENERGY STAR rating. Utility data can be entered into Portfolio Manager to calculate the Energy Use Index (EUI) kBtu/Sq.Ft/yr. EUI is a good measure of a building’s energy use per square foot and is utilized regularly for comparison of energy performance for similar building types. The EUI is a good indicator of the relative potential for energy savings also. A low EUI indicates less potential for energy savings, while a high EUI indicates poor building performance therefore a high potential for energy savings.

Verify Energy Star Portfolio Manager data is correct and complete for your facility and ensure an Energy Performance rating or EUI score is showing up.

According to the Energy Star Portfolio Manager, the facility scored an Energy Performance Rating of XX out of a possible 100.

5.0 Facility Description

5.1 General Facility Description

The below information must be updated for facility.

The campus is comprised of a number of buildings, totaling approximately XX square feet, with over XX square feet of interstitial space. These buildings were constructed between XX and XX. The main hospital building was built in XX. The XX VA Healthcare System provides comprehensive medical care including acute/in-patient medical, surgical, and psychiatric care; extended / long-term medical and psychiatric care, rehabilitative inpatient care; and comprehensive outpatient care with multiple specialty services available. In addition, the Medical Center supervises a community nursing home care program which is one of the largest in the VA system. The XX VA provides services to more than XX veterans living in a ten-county area in west central Florida.

Buildings 1, 71, 100, 101, 102 and Fisher House are used in continuous 24 hours per day, 7 days per week (24/7). Other areas, such as the administrative, service and some patient common areas, are nominally one shift per day Monday-Friday, 9 hours per day, and 5 days per week (9/5). A campus map is shown below.

Building 100 contains the main chiller and boiler plants. The main chiller plant supplies chilled water to buildings 1, 20, 22, 23, 71, 100, 101 and 102 with hot water reheat for humidity control. The remaining buildings are served by a variety of DX units. Steam is supplied by three (3) natural gas boilers which supply 100 psi steam for the laundry, sterilization, kitchen, heating and hot water reheat for the air conditioning systems. Also, steam from the central system is converted to hot water for heat in buildings 1, 20, 22, 71, 100, 101, and 102. Each building has its own hot water converter. There are also two 150 gallon gas water heaters in the boiler plant and two in Building 1. Building 2 is equipped with older style radiators for heating.
