BOARD OF REGENTS BRIEFING PAPER

Agenda Item Title: Update on Progress of grid-based energy purchase reduction

Meeting Date: Feb 28/ Mar 1, 2013

2. BACKGROUND & POLICY CONTEXT OF ISSUE:

NRS 701.215, as amended by SB 358 of the 2009 Legislature, required The Director of the State Energy Office to prepare a state energy reduction plan which addresses a reduction in grid-based energy purchases by 20 percent by 2015. Baseline (2005) data for all state entities, including NSHE, has been collected for natural gas and electric purchases and it is expected that the State Energy Office will be presenting its plan to the 2013 Legislature.

It is still uncertain what the specifics of the State energy plan will be, and if, or to what extent, funding will be available to implement the recommendations. However, given the mandate that currently exists in Statute, NSHE institutions have provided an inventory of progress made in this area as well as planned future projects. A summary is attached for review which includes estimated savings (where available) as well as details on how the initiatives were completed without direct state funding (ex: rebate programs, grant programs, utilizing construction/ building renewal projects, etc)

3. SPECIFIC ACTIONS BEING RECOMMENDED OR REQUESTED:

None – information only

4. IMPETUS (WHY NOW?):

With the expectation that the State Energy Plan will be presented to the 2013 Legislature, NSHE has prepared an informational report that includes an inventory of progress made to the existing mandate in statute.

University of Nevada, Las Vegas Capital Projects/Institutional Practices

Facilities Management Department

Below is a summary of sustainability-related activities and projects undertaken or being planned by UNLV Facilities Management (FM) for FY 2011, FY 2012, and FY 2013.

UNLV's Facilities Management has a long history of utilizing technology and improved practices to make the campus as efficient as possible within the limitations of funding and resources. In the 1980s, FM installed Energy Management Systems with the technology that was available. In the 1990s newer technologies were added in multiple buildings on the campus. More recently, even newer technologies and metering systems are continually being installed to improve energy efficiency. In addition, turf reduction and more efficient water projects are being completed to improve water efficiency. All these efforts have resulted in not only reduced energy and water costs, but also have significantly reduced the UNLV greenhouse gas footprint.

ACCOMPLISHMENTS

ENERGY/RESOURCE EFFICIENCY- Recent Capital Projects

• In FY 2011, pneumatic temperature controls in the Thomas Beam Engineering Building were upgraded to direct digital temperature controls (DDC).

• In FY 2012, pneumatic temperature controls in the Ham Fine Arts and Beam Hall Buildings were upgraded to DDC.

ENERGY/RESOURCE EFFICIENCY- Facilities Campus-wide

• Lighting retrofits are being conducted in existing campus buildings for higher efficiency lighting systems. Additionally, a new standard for lighting in campus buildings has been developed that eliminates incandescent lighting in favor of Compact Fluorescent Lights and LED lighting. FM has some test sites for LED fixtures.

• Light sensors have been installed in new and existing facilities that automatically turn off lights in many classrooms and offices when they are not in use.

• Carbon dioxide sensor and controls have been installed to reduce energy use and maintain air quality in several UNL V facilities.

• Chiller retrofits are being conducted on campus to install higher-efficiency chillers. • Higher-efficiency motors are being installed in various types of equipment in campus

facilities. • Hydronic HVAC equipment, where applicable, is being optimized to condition for a

temperature differential as opposed to target flow rates. • Programmable thermostats are being retrofitted to allow for set point management of

temperatures based on conditions and occupancy. • Facility controls are being reprogrammed to optimize HV AC compressor operation on

rooftop split-system units.


2

• Boilers are being replaced with more efficient units as needed. • Temperature settings in buildings are being increased in the summer and reduced in the

winter to reduce electrical and natural gas use. • Paints, adhesives, carpets and composite wood used in the building have low amounts of

volatile organic compounds. • A hazardous material management and disposal program has been designed as a part of

the building facilities and operations. • The university has implemented a "green" housekeeping plan in the building that focuses

on enhanced custodial training and the use of environmentally safe cleaning products.

WATER EFFICIENCY

• About 23,790 square feet of turf was converted to desert landscaping in 2012 with an estimated water savings of over 1.3 million gallons of water, and more conversion is scheduled for 2013 and beyond. The overall estimated annual water savings due to projects completed since 2000 is over 58.0 million gallons.

• Low-flow water fixtures are installed in facilities when practical. These use 20-30 percent less water than required by the Energy Policy Act of 1992.

• A new water treatment contract is in place to obtain a more efficient water treatment system for boilers and cooling systems. This action should save water, extend the life of equipment, and improve efficiency.

• In FY 2012 about 15 hydration stations were installed in multiple locations on campus to reduce the use of plastic water bottles.

POLICIES AND PROCEDURES

• UNLV's President has signed the American College and University Presidents Climate Commitment in August 2008. As part of this commitment, UNL V developed a Climate Action Plan as a collaborative effort of the Sustainability Committee and a group of Law students who were selected to partner with the National Association of Environmental Law Society in developing this plan. Facilities Management continues to support the plan with its decisions and practices.

• The Sustainability policies and procedures, developed and implemented in 2008 are ongoing and fully adopted by Facilities Management. Emphasis is on energy efficiency, purchase, and use of only Energy Star products, and the LEED Silver equivalency program for new construction, renovations and maintenance.

• A greenhouse gas emission tracking process is in place. • The university meets the federal requirement for alternative fuels by buying vehicles that

use diesel or E85 fuel. Nearly all of UNLV maintenance fleet vehicles are electric: out of a total of 201 vehicles, 14 7 are electric carts, 2 are solar-powered carts; 21 are alternative fuel vehicles; and only 31 are traditionally fueled vehicles. Additionally, the university has some older propane/natural gas vehicles. The university also has several hybrid gas-electric vehicles.

• Paints, adhesives, carpets, and composite wood used in buildings have low amounts of volatile organic compounds.

• UNL V has implemented a "green" housekeeping plan that focuses on enhanced custodial training and the use of environmentally safe cleaning products.

OTHER ITEMS


3

• UNLV Facilities Management continues to support and comply with guidance from the Sustainability Council that serves as an advisory group for various sustainability efforts related to campus research, education, and community engagement.

• UNLV and Staff received several awards for water efficiency during FY 2011 & 2012. Recognition came from the Southern Nevada Water Authority, USA Tree, and others.

NOTABLE SUCCESSES

• During FY 2012, buildings maintained and supported by FM have realized energy and cost avoidance of over 933,000 MMBTu's and more than $1.6 million. These savings, which are being realized due to the aforementioned actions, are ongoing and will continue to grow with new projects/measures. Avoidance is calculated from the base year FY 2001.

• During FY 2012, buildings maintained and supported by FM have realized a water and cost avoidance of over 354,000 KGALs and more than $1.2 million. These savings, which are being realized due to the aforementioned actions, including turf reduction and water efficiency fixtures, are ongoing and will continue to grow with new projects/measures. Avoidance is calculated from the base year FY 2001.

• The photovoltaic array at the LEED Gold-Certified Greenspun Hall has produced electricity at the average rate of about 292,000 KWh per year. At this rate of production the cost savings is approximately $29,000 per year.

• From FY 2011 through FY 2012 the following energy and water efficiency tasks were completed.

o Low Flush Urinals installed in 20 buildings. o LED walkway lighting installed in multiple locations on campus. o Corridor dimming ballasts installed in one building. o Converted from 32 watt T8 Lamps to 25 watt lamps in five buildings. o Partial installation of window tint on two buildings. o Installed daylight harvesting system for the corridors in one building. o Installed air cooled chiller on process loop in one building to allow shutdown of

chiller plant. o Retrofit 100 w mercury vapor lamps with LED.

• For FY 2011 and 2012, UNLV's Rebel Recycling program recycled approximately 690 and 720 tons of material, respectively.

• Received $6,500 rebate from NVEnergy for lighting efficiencies, dimming ballast, occupancy sensors and delamping

NOTABLE EFFORTS IN PROGRESS

• To be completed in FY 2013, a 50 Kilowatt photovoltaic array will be installed on the roof of Ham Concert Hall.

• To be completed in FY 2013, a 50 Kilowatt photovoltaic array will be installed on the roof of the Rogers Administrative Justice Building.

parking cover structures at the Southern Nevada Science Center (SNSC) in Las Vegas (2012).These three installations together provide approximately 462 kW of on-site electricity generating capacity to DRI; resulting in an estimated yearly average production of 936,761 kWhr per year.These projects will reduce the grid electrical consumption of the CRVB building by approximately 18% and the grid consumption of the SNSC building by approximately 70%. This equates to renewable energy generation of over 27% for the DRI Las Vegas Campus and over 3% for the DRI Reno Campus. Combined, these installations will save an estimated $83,050 per year in electricity costs. A review of the production record for the 21 kW system installed at the CRVB in 2009 shows that it has produced on average 9% more electricity than originally estimated. We expect that the two new systems may provide similar performance. A breakdown of current DRI electrical energy sources is shown in Figure 3.

Figure 3: Electrical Energy Sources for DRI

As stated above, the estimated yearly kWHr per year for the new photovoltaic systems is 936,761 kWhr per year. This equates to an estimated reduction in grid purchased power of 2.8 kWHr per year per gross square foot of building area. These projects alone bring DRI close to halfway to the 6.2 kWHr per year per GSF target for reduction of grid purchased power.

Funding support for these installations came primarily from the NV Energy Solar Generations Rebate Program. The State Public Works Division (SPWD) partnered with DRI for the 390 kW SNSC installation; the panels were purchased through a project awarded to Hamilton Solar by

the SPWD. The solar panels for the CRVB installation were purchased through Black Rock Solar.

Current & Future Projects To meet the electrical energy use reduction target, DRI will continue to focus on on-campus generation. DRI (again partnering with the SPWD) submitted for the most recent NV Energy Solar Generations program, and was awarded two additional projects. One award was for a 50 kW system to be constructed at the DRI Las Vegas Campus, the other was for a 50 kW system to be constructed at the DRI Reno Campus. DRI & SPWD has petitioned the Public Utilities Commission (PUC) to increase the size of the Reno Campus system to 500kW. Pending resolution of PUC approval; availability of appropriate space to install such a system; and resolution of cost and funding requirements, DRI may be positioned to make significant further progress towards substantially complying with the 2015 target by the end of calendar year 2013.

Use of natural gas, as shown in Figure 2, is highly variable, with weather and use of natural gas to control temperature for large experimental systems as the primary volatile factors. DRI intends to continue to pursue energy conservation as the primary strategy to achieve the target reduction.

Research Installations DRI has recently constructed the Renewable Energy Experimental Facility (REEF) on the DRI-Reno campus. The REEF is designed as an energy net-zero infrastructure that can be operated off-grid. Energy, as both electricity and heat, is provided by solar photovoltaics (5 kW), wind turbines (3 kW), 400 ft2 of liquid-based solar thermal collectors, and 580 ft2 of air-based solar thermal collectors. The hot water and hot air generated by the solar thermal collectors are used to heat the facility in winter, and cool the facility in summer through the use of an absorption chiller. The generated electricity is used directly and also stored in batteries and hydrogen.When excess electricity is available, it is used to power a 5 kW hydrogen generator which is then stored as a gas. When the electrical demand has surpassed the supply, the hydrogen is then combusted in an internal combustion engine and converted to electricity through a belt-driven alternator. To ensure energy security, the same engine has the capability to run on propane.

SUBJECT: Update: Compliance with NRS 701.215 – Reduction of Grid Based Energy Purchases

DATE: January 22, 2013

In response to your request dated December 27, 2012, CSN provides the following information on the projects/initiatives that address the goal of a 20% reduction in grid based energy purchases by 2015.

CSN continues to work on the reduction of grid based energy usage and has achieved a 9.30% reduction in electrical costs since 2005. The College is accomplishing this through a variety of means:

1. Deferred Maintenance Funds – Approved deferred maintenance funds are being used to replace mechanical equipment that has been sustained far beyond its normal life expectancy. Installing HVAC controls that provide for greater energy efficiency are a part of these projects.

CSN has a backlog of $100 million in deferred maintenance needs. The available funds must be applied to the projects that are deemed of the greatest urgency; the energy efficiency projects are in competition with other critical needs. Despite the limited funding, the College was able to complete the projects using deferred maintenance funds this past year:

Henderson Campus, “B” Building--chiller and boiler replacement;Palo Verde (Summerlin) High Tech Center--cooling tower replacement/pumps and plate addition; andWestern High Tech Center--cooling tower replacement/redundancy addition.

2. Capital Improvement Funds (CIF)–CIF funds were used to provide Heating/Ventilation/Air Conditioning (HVAC) remodels, and the following projects were completed during this last year:

Cheyenne Campus, Main Building - added heating to Variable Air Volume (VAV) mechanical units and replaced VAV units that were failing due to age and usage.Charleston Campus, “D” Building - HVAC controls were completely retrofitted/upgraded to increase efficiency;Cheyenne Campus, Culinary Building - HVAC controls were completely retrofitted/upgraded to increase efficiency; Cheyenne Campus, Horn Theater–The dedicated boiler was removed and the building tied into the central plant boiler which enhanced efficiency as well as providing system redundancy.


Jamie Hullman January 22, 2013Page 2

3. State Legislature Projects – The College recently completed a $2 million retrofit of the existing mechanical system at the Cheyenne campus. While this was just a start to a much larger project, it was desperately needed. This retrofit provided the campus with more energy efficient mechanical units and controls, as well as new lighting controls to reduce electrical costs.

In the 2013 legislative session, the College has requested funds for mechanical renovations at the Charleston “B”, “D” and “E” buildings, as well as to continue the work in the Cheyenne Campus Main building.

4. Operating funds – As existing equipment breaks down and needs to be replaced, the College is using operating funds to acquire replacement equipment of greater energy efficiency. For example, last year the College retrofitted approximately 5% of the lights in the Charleston Campus “B” Building to new efficient LED lighting.

5. Solar Energy Master Plan – The College created a Solar Energy Master Plan which identifies for each campus the potential locations of solar energy panels to achieve the greatest efficiency. Since the Master Plan was completed, CSN installed 100 Kw each at the Cheyenne and Charleston Campuses, and 84Kw at the Henderson Campus. Funding for these panels was obtained through the Nevada Energy Solar Incentives program. In addition, the College has been approved this year for another 50 Kw installation at the Cheyenne campus.

The College continues to strive to achieve enhanced energy efficiency of buildings on its campuses. The following is a list of projects that will be under construction in the next year or for which we are seeking funding:

Campus Project Funded/Unfunded

1. Cheyenne 1100 Building – Boiler is to be replaced and the pipes will tie into Central Plant Boiler similarly to the Horn Theater project described in #2 (above).

Unfunded

2. Cheyenne Horn Theater--Controls retro/upgrade from pneumatic controls (which must be manually adjusted) to Direct Digital Controls (DDC) which are designed to improve overall efficiency as well as to allow for system adjustment that can be completed from a remote location via computer..

Unfunded.

3. Cheyenne Horn Theater 50Kw solar energy panel installation Funded -- NV Energy Solar

Incentive Rebate4. Charleston Continue to retrofit lighting on campus to LED, when possible Operating Funds5. Charleston “B” Building -- second floor pneumatic HVAC controls to be

converted to Direct Digital Control along with heating element added.

Partial Funding

6. Charleston 16 Variable Air Volume (VAV) mechanical units are scheduled for upgrade.

Capital Improvement

Funds7. Charleston Mechanical control replacement is scheduled for “C”, “G” and

“H” Buildings2013 Deferred Maintenance

Request8. Charleston Re-design of the “G” Building, second floor mechanical system.

Currently, 100% outside air is replenished within the entire building; this is not necessary for the existing labs. The system will be re-designed to eliminate that requirement. This will increase efficiency since there will be less volume of incoming air to heat and cool.

Unfunded

Campus Project Funded/Unfunded

9. Henderson “A” Building air handlers require replacement since they are beyond their expected lifespan. Greater efficiency will be achieved.

Deferred Maintenance Bond

10. Henderson “A” Building – HVAC Controls are being installed to replace failing equipment as well as to upgrade for energy efficiency.

Deferred Maintenance Bond

11. Henderson “B” Building – Fan coils require renovation since they have been in use beyond their life expectancy. The addition of Direct Digital Controls (DDC) is designed for greater efficiency as well as capability that allows for system adjustment that can be completed from a remote location via computer.

Partial Funding

12. Mesquite Site

Mesquite site requires a partial mechanical replacement; this is the first phase of a larger project that will be completed as funding permits.

Partial Funding

13. All Campuses

Exterior lighting controls are planned to be added throughout all campuses to increase the energy efficiency.

Operating Funds (as replacement is necessary)

CSN is fortunate in that approximately 28% of its campus buildings are less than 10 years old and were constructed with energy efficiency in mind. Given the limited funding that is available CSN has made significant progress toward the goal of a 20% reduction in grid based energy purchases. The College is committed and will continue to work towards this goal in the future.

TMCC NRS 701.215 Energy Reduction Update Request Update 2013

Energy Efficient Lighting - TMCC Began changing out light fixtures to energy efficient lighting in 2005. These lighting retrofit projects were funded primarily from grants and rebates from NV Energy and ARRA. To date lighting has been replaced in all TMCC facilities.

Occupancy Sensors — Occupancy sensors have been installed in 70 rooms throughout all TMCC sites. The sensors turn room lights on when the room is occupied and automatically turn lights off when no one is in the room.

HVAC Efficiency — Since 2005 total building HVAC replacements were completed at the IGT Applied Technology Center using ARRA funding, both buildings at the Meadowood Center. A partial HVAC replacement was completed in the Red Mtn. Building. Major HVAC components in Phase II and approximately half of Phase III of the building were replaced with high efficiency units. All the HVAC renovations included both the cooling equipment (electricity) and the heating equipment (gas). Additionally, direct digital controls (DDC) have been installed or upgraded in all major TMCC facilities to ensure maximum operating efficiency.

Variable Frequency Drives (VFD’s) – have been added to large motors and pumps in all major facilities

Temperature Control — Summer and winter temperatures have been standardized for all TMCC facilities. This move is estimated to save $50,000 per year in energy costs.

Renewable Energy — TMCC has constructed a 9 kW photo voltaic (PV) array at the IGT Applied Technology Center which will also be used as a teaching lab for students studying renewable energy. The Solar Lab was largely funded through a grant from NV Energy. It went online in 2009. A 5 kW and a 2.6 kW wind turbine were installed on the Dandini campus in 2012. A 50 kW photo voltaic array was installed on the Dandini campus also in 2012. A 100 kW photo voltaic array is currently in the planning phase and is scheduled to be installed on the Dandini campus in 2013.

Information Technology — Since 2005 TMCC has implemented an automated power shutdown on all academic lab, classroom computers and student services kiosks when not in use, saving an estimated 160 operational hours each day with an annual estimated energy savings of $49,000.

Equipment Replacement — TMCC buys Energy Star compliant LCD monitors to replace less efficient CRT Monitors and selects high efficiency components when replacing building equipment.

Reduced Commuting - With the implementation of the college's Web site, Web College's online learning management systems, and the use of virtual private networks, some faculty, staff and students spend less time in the buildings to obtain information, teach, or take classes which reduces the amount of cooling needed and a reduction in the use of electrical equipment.

Utility tracking software has also been installed and is currently being populated with data, so that better analysis of power and gas consumption can be made.

Future Projects — TMCC's Capital Improvement Program (CIP) includes the replacement of the remaining aging major components of the heating and air condition systems in the Red Mountain Building. The CIP also includes a project to seal the Red Mountain Building’s exterior envelope


minimizing migration of heated or cooled air to the exterior and replace single pane windows with energy efficient double pane glass. TMCC also plans to continue installing occupancy sensors where appropriate and as funding is available. Replacing parking lot lighting with high efficiency LED lamps is currently being evaluated and TMCC is teaming up with Black Rock Solar to complete a professional energy audit of its buildings to see where more opportunities exist to save energy.
