Arkansas Administrative Code
Agency 168 - Arkansas Economic Development Commission
Rule 168.00.10-001 - Energy Efficiency and Natural Resource Conservation in Public Buildings
Current through Register Vol. 49, No. 9, September, 2024
INTRODUCTION
Public buildings can be built, renovated and operated using sustainable, energy-efficient practices and technologies that save money, reduce negative environmental impacts and improve employee performance. Act 1494 was passed by the General Assembly to show that the State of Arkansas can design and operate its buildings in order to "Lead By Example". The two programs established by Act 1494 are the Sustainable Public Buildings Program and the State Buildings Energy Management Program.
The main objectives of the Sustainable Public Buildings Program are to:
1. Avoid resource depletion of energy, water, and raw materials;
2. Prevent environmental degradation caused by facilities and infrastructure throughout their life cycle; and
3. Create buildings that are cost effective, habitable, safe, and productive.
State-owned buildings and buildings owned by an institution of higher education can be improved by establishing specific performance criteria and goals for sustainable, energy-efficient public buildings that are based on recognized, consensual standards with a scientifically proven basis and a history of successful performance.
The role of the Arkansas Energy Office (AEO) is to develop and administer policies, procedures and technical guidelines for compliance with the criteria and performance standards for the construction and renovation of major facilities. The AEO will also develop and administer guidelines for state agencies to manage energy, water and other utilities that will reduce total energy consumption per gross square foot, to the maximum extent practicable, for all existing state buildings. This energy management program is designed to achieve compliance with State Laws and Policies concerning energy efficiency goals through the implementation of energy conservation measures and monitoring of the utility costs and usage.
The main objectives of the State Buildings Energy Management Program are to:
1. Promote energy conservation in buildings owned by public agencies and institutions of higher education, and therefore reduce the rate of expenditures of public dollars;
2. Develop and adopt guidelines and technical guidance for compliance with the efficient energy management and operation of state buildings; and
3. Reduce the use of energy, in accordance with ACA § 25-4-406, twenty percent (20 %) by the end of fiscal year 2014 and thirty percent (30%) by the end of the fiscal year 2017. This reduction will be measured in total energy use per gross square foot per year compared to fiscal year 2008.
CHAPTER 1 : ADMINISTRATION AND ENFORCEMENT

CHAPTER 5 : PURCHASE OF A CONSTRUCTED OR RENOVATED BUILDING
CHAPTER 6 : STATE BUILDINGS ENERGY MANAGEMENT PROGRAM
The AEO will require Strategic Energy Plans from state agencies to insure state agencies have developed and implemented plans intended to reduce total energy consumption per gross square foot for existing state buildings by twenty percent (20%) by 2014 and thirty percent (30%) by 2017 based on energy consumption for the fiscal year 2008.
Strategic Energy Plans for all agencies will be submitted once every 5 years to include annual updates each year on October 31st. The 5 year plan and updates must be uploaded to the Arkansas Energy Office website
www.arkansasenergy.org for AEO review and approval. All agencies are required to report unless specifically exempted by law.
Each agency shall include in their Strategic Energy Plan a description of the agency's goals and strategies to meet the 2014 and 2017 goals and a plan for continued energy efficiency efforts. The plan must document the current status of the agency in implementing energy efficiency improvements, report the success and challenges of the program to date, and describe the plans to continue improvements.
At a minimum, the Strategic Plan must include the following:
A suggested Strategic Plan Outline is provided in Appendix A. More detailed templates and guidelines for plans will be available from the AEO website.
ESPM shall be used by each agency to organize their data to establish a baseline of energy usage for fiscal year 2008 and track subsequent energy, water and other utility usage and costs. Each agency must establish accounts in ESPM. To establish accounts, facility and utility bill data must be gathered and entered into the accounts, starting with data for July, 2007. These accounts must be updated on a monthly basis. The Energy Manager in each agency will be the point of contact for information in this database. Agencies will give the AEO "Share" permission to view and use the account data in ESPM. This data will allow verification of the energy savings by the agency for each facility and will be aggregated to show the energy savings by an agency and state agencies as a whole. The AEO will consider changes in the baseline of an agency on a case by case basis. Requests for changes to the baseline should be forwarded to the Director of the Energy Office
A LCCA shall be performed by state agencies on all building energy and water designs related to state agency facilities. Methods for performing a LCCA are listed in Appendix C. The AEO requires the use of NISTIR 85-3273-21 Energy Price Indices and Discount Factors for Life-Cycle Cost. Alternative LCCA methods and indices/discount factors may be used only upon approval by the AEO. Projects must consider the economic life of the building system and components when making this determination. The results of the LCCA must be reported to AEO and the report must include economic assumptions used in the calculations.
Energy Managers should periodically evaluate the performance of the facilities used by the agency. In order to perform an adequate investigation, the Energy Manager should determine if the facility needs justify an energy audit or a more intensive recommissioning or retrocommissioning. Proper evaluation of facilities will identify energy efficiency measures that need to be taken to improve the performance of the facility. The AEO recommends audits or commissioning activities be performed every 5 years. Appendix B contains supplemental information for the different levels of auditing that can be performed on buildings. The Agency energy manager shall ensure that architects licensed by the Arkansas State Board of Architects or professional engineers licensed by the Arkansas State Board of Registration for Professional Engineers and Land Surveyors are engaged to provide energy audit or commissioning services when such services involve the practice of architecture or engineering in accordance with Arkansas Code Annotated § 17-15-101 et seq and 17-30-101 et seq respectively.
The AEO will offer education and training as funds are available. The education program will include various levels of training relating to the design, operation and maintenance of facilities, life-cycle cost analysis, energy audits, retro-commissioning and energy management. The training will be open to energy managers, chief financial officers, facility managers, capital project coordinators of public agencies, architects and engineers.
The AEO shall develop one level of education and training requirements for the chief financial officer of each public agency that is appropriate for the chief financial officer's level of involvement in projects under this section. The AEO shall develop, for each public agency that is responsible for the payment of the agency's utilities, another higher level of education and training requirements for the facility manager of the agency that is appropriate for the facility manager's level of involvement in projects under this section. This level of education and training shall also be a requirement for the capital project coordinator of an agency involved in a project under this section. The AEO shall develop a highest level of education and training requirements for the architects and mechanical design engineers that are involved in the design of projects under this section that is appropriate for their level of involvement in these projects.

APPENDIX B: ENERGY AUDITS AND AUDIT PROCEDURES
Modifications
This level of engineering analysis focuses on the potential capital-intensive projects identified in the Level 2 analysis and involves more detailed field data gathering as well as a more rigorous engineering analysis. It provides detailed project cost and savings calculations with the high level of confidence required for major capital investment decisions. This audit alternatively is called a comprehensive audit, detailed audit, or technical analysis audit. It expands on the Level 2 audit by providing a dynamic model of energy use characteristics of both the existing facility and all energy conservation measures identified. The building model is calibrated using actual utility data to provide a realistic baseline against which to compute operating savings for proposed measures. Extensive attention is given to understanding not only the operating characteristics of all energy consuming systems, but also the situations that cause load profile variations on both an annual and a daily basis. Existing utility data is supplemented with sub-metering of major energy consuming systems and monitoring of system operating characteristics.

APPENDIX D: ENERGY CONSERVATION MEASURES AND EXAMPLES
Some examples of energy conservation include the following:
Energy Conservation Measure Descriptions Lighting
Install new and/or retrofit lighting fixtures
Fluorescent lighting
This measure applies to buildings where existing fluorescent lighting is not up to date. In most cases, existing lighting has T12 lamps and magnetic ballasts. Older buildings have standard magnetic ballasts while newer construction may have energy-efficient magnetic ballasts.
This measure consists of upgrading T12 fixtures to new T8 lamps and electronic ballasts, upgrading exit signs, and lighting controls and installing occupancy sensors where economical. In areas with long burn hours, the fixture retrofit may also include a specular reflector to increase fixture efficiency.
Incandescent Lighting
This measure applies wherever incandescent lighting still exists and has more than "occasional" burn hours. The upgrade consists of either a) replacing the incandescent lamp with a compact fluorescent lamp, or b) installing a new light fixture with an either a compact or linear fluorescent lamp.
Install Occupancy Sensors
This measure consists of installing occupancy sensors in classrooms, laboratories, offices and other areas where lights may be left on while the area is unoccupied. In small rooms, wall switch occupancy sensors may be adequate. In larger rooms, it may be necessary to use ceiling or corner mounting locations.
Install new and/or retrofit exit light fixtures
This measure consists of upgrading all existing incandescent and fluorescent lamp exit signs to newer lamp technology such as an LED light source. The measure can be accomplished by installing new exit signs or retrofitting the existing exit signs with upgrade kits as applicable.
Replace existing HID lighting with high intensity fluorescent technology
Large areas with high ceilings are good candidates for new high-bay light fixtures using the more efficient high output fluorescent lamp technology such as T-5 fluorescents. This upgrade measure will apply gymnasiums, warehouse space, and high bay workshops. Interior spaces such as libraries and atrium areas, which may currently use HID lighting, could also be good candidates for this upgrade. In addition to the lighting energy savings (about 50% vs. metal halide) the new lighting is "instant on" and can be controlled with occupancy sensors and dimming controls to produce even more savings.
Replace existing Parking-lot lighting with high intensity fluorescent technology
This measure should incorporate the latest technology in outdoor florescent lighting fixtures and controls.
Controls
Install/activate outdoor reset controls
This measure consists of the installation of improved controls, which measure the temperature of outside air. They adjust the boiler water temperature to optimize heating system efficiency by reducing water temperature to the minimum required to provide heat satisfactorily. The upgraded controls also turn off the circulating pumps when the building requires no heat. In some facilities, equipment may exist that is designed to perform this function, but it may be inoperable, malfunctioning or deactivated. In these situations, the control will be upgraded, replaced or activated to perform this function.
Install/activate night setback controls
This measure consists of the installation of new temperature controls, which lower temperatures during unoccupied periods in the heating season - primarily nights, weekends and vacation breaks. The same setback controls may also apply to air-conditioning during the cooling season. In some facilities, equipment may exist that is designed to perform this function, but it may be inoperable, malfunctioning or de-activated. In these situations, the control will be upgraded, replaced or activated to perform this function.
Install premium efficiency motor(s) and/or variable speed drives
This measure consists of replacing standard efficiency motors with premium efficiency motors and installing variable speed drives on pumps and/or fans, which run at constant speed but have variable loads. The measure is normally limited to motors larger than 2 HP and with run times greater than 2500 hours per year.
Install/activate economizer cooling
This measure applies to those facilities that have air-conditioning systems and lack the capability to cool the facility using outside air. It requires the addition of economizer controls that measure the temperature and humidity of outside air and use it for cooling whenever feasible. In some facilities, equipment may exist that is designed to perform this function, but it may be inoperable, malfunctioning or de-activated. In these situations, the control will be upgraded, replaced or activated to perform this function.
Install demand controlled ventilation
This measure consists of installing the equipment necessary to control outside air brought into the building (or a particular area within a building) according to its occupancy. Spaces without demand control ventilation are generally designed to provide ventilation based on the maximum possible occupancy for the space. During periods of lower occupancy, the space may be significantly over ventilated and use unnecessary energy. In most cases, this measure requires an indoor air quality (IAQ) sensor, a variable damper on the outside air inlet and a control system that varies the damper opening according to the real time IAQ. Gymnasiums, auditoriums and other large areas that have widely varying occupancy are good candidates for this measure.
Install intelligent fan controls on kitchen and lab ventilation hoods
This measure consists of installing specialized fan controls or exhaust hoods that can regulate the kitchen or lab hood exhaust fan speed according to the actual cooking or occupancy activity being performed under the hood. The systems often use variable speed drives on the exhaust fan motors.
Install small energy management system (EMS) with remote access
This measure consists of the installation of a small, microprocessor-based energy-management system (EMS), or the upgrade of an existing EMS system, which will schedule and control the main energy consuming equipment in the building. In addition to optimizing the building's control functions the system will be capable of remote access so its conditions can be monitored from anywhere using a phone or Internet link.
In particular, the system must be capable of remote monitoring of space temperatures and the status of boilers, furnaces, pumps, fans and AC units. The EMS system must be capable of interfacing with existing EMS equipment and controls unless a completely new system is more economical.
HVAC & Plumbing Measures
Install more efficient heating equipment
Most of the heating systems utilize either a warm air furnace or a hot water boiler. Fuel is predominantly oil although gas and propane are available in some locations. This measure consists of replacing the existing furnace or boiler with a new, more efficient unit (based on AFUE) or replacing rooftop units. Multiple modular boilers are preferred over large single units. Also, facilities using natural gas or propane for fuel should consider high efficiency condensing boilers.
Install more efficient Air Conditioning (AC)
Many buildings have areas with air conditioning to ensure student and staff comfort during the summer months. These small AC systems vary in age, size and efficiency. This measure is for the installation of more efficient (higher SEER) new AC units. Many of these new units have dual stage compressors so they operate at lower power (and higher efficiency) for all but the peak summer days.
Install new higher efficiency water heater
This measure consists of replacing an old water heater with a new, higher efficiency water heater or heat pump water heater. Heat pump water heaters are particularly effective in buildings that use a boiler to produce domestic hot water during the heating months. With a heat pump water heater the main boiler can then be shut down. Other improvements in water heaters include units with pilot-less ignition, a flue-gas damper, thick exterior insulation and a high efficiency heat exchanger. The most efficient units use a burner with a forced-draft fan. This measure will also consider the installation of an instantaneous water heater, which may be more applicable for areas that only need hot water for hand-washing type activities.
Install water conserving plumbing fixtures and devices
This measure will replace or retrofit existing inefficient water-consuming plumbing fixtures such as toilets, urinals and faucet aerators with new water conserving lower-flow fixtures, devices and controls. Measures should be considered to control costs and usage of outside watering for landscaping purposes.
Building Envelope
Add additional glazing panel and/or retrofit existing glazing system
This measure consists of adding an interior or exterior glazing panel to the existing widow system to boost energy efficiency and reduce air infiltration. Alternatively, a retrofit of the entire existing glazing system should be considered where economically feasible.
Increase ceiling/roof insulation
This measure consists of adding insulating material to the ceiling or roof areas of buildings that presently have little or no ceiling/roof insulation. In most cases it will consist of additional fiberglass bats, rigid panel insulation or blown-in insulation.
Alternative Work Items
Install small high efficient boiler for summer use
This measure consists of the installation of a small "pony" boiler for use during the spring, summer and fall periods. When possible, the unit should be a condensing boiler, which operates at very high efficiency when at low load.
Replace existing rooftop heating/ac units
This measure will investigate the economical replacement of the existing roof top heating and cooling equipment with higher efficiency units.
Weather-stripping, sealing and caulking
This measure consists of lowering the air infiltration rate of buildings through the application of weather-stripping materials, caulking and sealants around exterior fenestrations. Old and deteriorated materials shall be removed prior to the application of new materials.
