Special Thanks
                 While the Bonneville Power Administration funded and managed the overall development of the Northwest Energy Efficiency
                 Technology Roadmap, the effort would not have been possible without the active engagement of thirty-five representatives
                 from twenty organizations. In particular, the members of the newly formed Regional Emerging Technology Advisory Committee
                 played a key role the roadmap’s creation. Those members include representatives from Bonneville Power Administration,
                 Northwest Power and Conservation Council, Northwest Energy Efficiency Alliance, Electric Power Research Institute, Pacific
                 Northwest National Laboratory, Washington State University Extension Energy Program, Energy Trust of Oregon, Puget Sound
                 Energy, Snohomish Public Utility District, Seattle City Light, Idaho Power, and Avista. Thanks as well to the project team, who
                 worked behind the scenes to plan, coordinate, analyze, evaluate, revise, and prepare everything needed to pull this roadmap
                 together in such a short amount of time. Without the help of contractors from the Department of Engineering and Technology
                 Management at Portland State University, the Washington State University Extension Energy Program, Livingston Energy
                 Innovations, and Energetics this roadmap would look very different than it does today.

Beginning in December 2009, thirty-five experts from twenty organizations
pooled their efforts to develop an energy efficiency technology roadmap that
would define a research agenda for the Northwest. The results of the
intensive ten-week effort, along with revisions based on critical comments
received following the release of a March draft, are contained in the                                                                                   Terry Oliver

High Priority R&D Programs
1. Better mini-split controls for variable refrigerant flow (VRF) applications: VRF and mini-splits, particularly with improved controls, can more efficiently
respond to space conditioning needs than conventional HVAC systems with air ducts. To successfully realize the opportunity associated with broad interest and
increasing application of variable refrigerant flow systems, more R&D is needed to optimize controls for mini-split system energy savings.

2. Heat recovery optimization routines such that economizer performance is not impacted: Make better use of exhaust air heat recovery and economizers.
Develop algorithms that would most efficiently optimize the use of both systems.

3. Research to move air sealing to prescriptive and into hands of quality control and out of contractors: Building air sealing is too often poorly done by
contractors. By having highly trained specialists perform air sealing, average infiltration rates will drop.

4. Shop floor innovative technologies similar to auto industry: Manufactured housing is generally overlooked. It and can generate big energy and financial
benefits with some optimization and lessons from other industries.

5. Categorize building stock for better, easier testing: Development of meaningful taxonomies of building stock will allow aggregation into categories for more
efficient and expeditious energy assessment.

6. Application technology that is easy and inexpensive: If a common methodology for air sealing common building envelope types could be developed, a wider
range of builders could implement it more effectively and consistently.

7. Human factor (usability and comfort): Technology elements for broad application of task/ambient lighting exist; need human factors R&D on design and
control approaches for this technology to achieve its potential in the market.

8. Develop cheap and reliable smart plugs. Create protocols for appliance compatibility with smart plugs; study human factors for design, installation, and
use of smart plugs: Making smart outlets a standard feature in new construction requires innovation in technology and building industry practices.

9. Next-gen coatings for triple-glazed IGs with superior SHGC and U-factor ratings: Develop a window with high R-value and low solar heat gain coefficient
(SHGC) that performs well in all seasons and climates.

10. Easier, cheaper daylight modeling tools that give energy benefits: Improve modeling and design tools, making them easy to use for electricians (not just
lighting designers) and making them affordable and reliable.

11. Variable refrigerant flow (VRF), more information about energy use, improving controls: Develop reliable engineering and technical information on how to
optimize VRF energy savings while assuring comfort and reliability.

12. Study of what energy management devices people actually use: Creating standard, easy-to-use EMS interfaces can move them from fairly clunky software
that is only occasionally accessed to being regularly used by maintenance personnel along with other duties. Human factors and usability studies will allow for
optimization of device design, interface design, and communication protocols for the end user.

13. What is there beyond fiberglass that has excellent insulation characteristics and is lightweight and durable in window applications?: While most
advances in window technology focus on glazing, frame insulation also needs to be improved. Fiberglass has relatively low thermal conductivity and is durable
but costly.

14. “Smart” material that fills all cavities, is mistake-free, and inexpensive: While affordable, effective insulation exists, too many installers miss or create
cavities, so new materials are needed that are easier to use effectively.

R&D Project Summaries
   Categorize building stock for better, easier testing: If a wide range of building stock is sorted into categories, energy assessments can be performed more
    expeditiously.

   Research commercial heat recovery options for providing space and domestic water heating for adjacent residential buildings: With co-located
    commercial and residential buildings, commercial waste heat recovery can be more cost effective by utilizing it for adjacent residential use.

R&D Project Summaries
   Develop next-generation coatings for triple-glazed windows with low SHGC and R-value over 5: Develop a glazing product with high R-value and low SHGC
    that performs well in all seasons and climates.

   What is there beyond fiberglass that is highly insulated and lightweight?: Other materials may be available to allow a more effectively insulated frame.

   Integral low-E and PV windows: By applying a thin, clear PV film on windows, power can be generated to help buildings achieve Net Zero Energy status.

   Add a small PV panel to electrochromic windows that will increase tinting proportionally or insulate during the cooling season: An electrochromic
    window powered by a small PV panel can vary tint with solar heat during the cooling system without low-voltage power distribution.

   Glazing, vacuum-filled 1-pane, low-E windows: Combining the insulating property of vacuum between panes and low-E coatings results in a higher R-value
    glazing.

   Heavily insulated electrochromic windows: Adding electrochromic tinting to a high R-value glazing allows a window to block heat transfer and selectively
    block solar radiation.

R&D Project Summaries
   Research to move air sealing to prescriptive and into hands of quality control and out of contractors: Building air sealing is too often poorly done by
    contractors.

   Application technology that is easy and inexpensive: If a common methodology for air sealing common building envelope types could be developed, a wider
    range of builders could implement it more effectively and consistently.

   Cal Arch, Energy I2 Action, Ecotype tool: The broad adoption of building energy labels requires better energy modeling tools.

   Energy information systems – numerous existing (see LBNL reports): Energy information and systems to collect and make it available to building designers
    and facility management staff are key to achieving carbon-neutrality by 2030, which requires buildings, which contribute almost 50 percent of greenhouse
    gas emissions, to be designed to 50 percent of current average energy use for the building type and region. The establishment of building energy labeling
    requires sharing of enough building energy performance data to establish performance benchmarks in addition to ratings.

R&D Project Summaries
   Electric system compatibility: Unlike most other light sources, most LED products require conversion of AC to DC power, which introduces system
    inefficiencies. Research a way to avoid this.

   Thermoelectronic heat recovery from LEDs: Heat dissipation is essential to good performance of LED lighting. One approach suggested for dissipating the
    heat is to actually generate electricity from the generated heat using thermoelectric (or thermoelectronic) devices (similar to PV, but they operate on heat, not
    light), increasing the effective efficiency of the system.

   Substrate growth improvements @ DOE contractors: LEDs are grown on substrates and there is ongoing research to improve the process for such things as:
    higher external quantum efficiency performance, better electrostatic discharge durability, simple low-cost fabrication, high product yield with high brightness,
    and better heat management (DOE SSL).

   SSL life extension @ Philips, Cree, etc.: Electrical and thermal design of the LED system or fixture determine how long LEDs will last and how much light they
    will provide. Driving the LED at higher than rated current will increase relative light output but decrease useful life. Operating the LED at higher than design
    temperature will also decrease useful life significantly. (DOE SSL)

   SSL heat dissipation @ Philips, Cree, NSC, etc.: Excess heat directly affects both short-term and long-term LED performance. The short-term (reversible)
    effects are color shift and reduced light output, while the long-term effect is accelerated lumen depreciation and thus shortened useful life. (DOE SSL)

   Improved light extraction @ Philips, Cree, etc.: Constant development of higher efficacy LED/driver packages is ongoing with the goal of more lumens/watt
    without sacrificing lamp life.

   Can it focus better? @ Philips, Cree, etc.: Designing luminaires that take best advantage of SSL characteristics to deliver luminous flux on the task rather
    attempting to mimic traditional fixtures leads to the best performance. The DOE and other groups are sponsoring a variety of design competitions.

   Better fixture design @ many luminaire manufacturers: Designing luminaires that take best advantage of SSL characteristics rather than look like
    traditional fixtures leads to the best performance. Dealing with replacement parts for premature failure is an issue. Lack of interchangeability will hamper the
    market. The DOE and other groups are sponsoring a variety of design competitions.

R&D Project Summaries
   Cheaper, simpler self-calibration: Some controls try to adjust settings according to the habits of the user. Cheaper, simpler, and more effective ways of
    doing this will be helpful. This will likely take advantage of better predictive modeling.

   Predictive modeling for dynamic lighting needs: Research on modeling that will better predict lighting needs by taking into account the time of day and day
    of the week will make lighting controls more useful and more acceptable to users.

   Dynamic control of occupancy-based lighting [WattStopper, Lithonia?]: Likely using the modeling from above, controls that dynamically predict lighting
    needs by taking into account the time of day and day of the week for the user will make lighting controls more useful and more acceptable to users.

R&D Project Summaries
   Review and audit of various luminaire designs for various lighting applications.: The importance of luminaires has often been overlooked in specifications
    and codes. Need to rate luminaires so better data are available, then educate architects and designers on which luminaires to use for which applications to
    improve efficiency and effective lighting.

   Human factors – research on parameters for optimizing @ LRC: Regardless how efficient lighting is, it's only useful if it actually helps humans. Research on
    the relevant human factors is important and may apply to luminaires.

   Legitimize mesopic lighting @ LRC: Mesopic lighting, to be fully accepted by the market, needs to have standards changed to legitimize it. Provide data to
    support IES standards modifications.

   Change IES metrics @ IES: Metrics and standards have evolved as we learn more about how humans use light most effectively. More work needs to be done
    to continue to improve IES metrics.

R&D Project Summaries
   Cheaper and simpler self-calibrating dimming controls: Making daylighting cost-effective continues to be a challenge. Cheaper, easier to use, and self-
    calibrating controls can help to make daylighting more attractive. Need research.

   Skylight design: Making daylighting cost-effective continues to be a challenge. Effective, affordable, leak-resistant skylight design could help make
    daylighting easier and more affordable to adopt.

   Research human and technology barriers @ LRC: Investigate both human factors and technical barriers to adopting daylighting.

   Core Lighting project @ UBC & CLTC: Daylighting has traditionally concentrated on perimeter zones (near windows). Current research is finding ways to use
    daylighting in core zones. More research is needed to find more affordable and effective ways of doing this.

   Optimize daylighting with PC use @ LRC: Research on how to effectively use personal computers to monitor and control daylighting.

   Software for daylight design – sensor placement @ CEC PIER: Develop good, affordable software for designing daylighting systems, including determining
    optimum placement of sensors.

R&D Project Summaries
   Behavior economics for how people use devices: To facilitate wide-spread adoption of sleep-mode technology, study the way the most common user groups
    interact with electronic devices so the sleep-mode technology will be compatible with their behavior.

   Accessible and simple interface controls: To facilitate widespread adoption of sleep mode technology, develop controls that are as simple or accessible as
    possible. If they're complicated or a hassle, they won't get used.

   Software compatibility with stand-by modes: To facilitate widespread adoption of sleep mode technology, it's not enough that it works well with end users
    and network administrators; ensure it's compatible with all the commonly used software applications and video games.

   Optimize user interface: Facilitate widespread adoption of sleep mode technology and optimized user interface.

   Responsive to gamers’ needs: Video games with sleep mode are losing scores.

   Responsive to late-night network updates: Sleep mode must become more responsive to late-night network administrative updates.

   User sensing controls – underway @ TV manufacturers, however this R&D is not accessible for collaboration: To facilitate widespread adoption of sleep
    mode technology, study the way the most common user groups use electronic devices so the sleep mode technology will be compatible with their behavior
    and not cause user inconveniences.

   Network management for computer networks: To facilitate widespread adoption of sleep mode technology, it's not enough that it works well with end users.
    Sleep mode also needs to meet the needs of network administrators; otherwise, they will not support (or will even disallow) its use.

R&D Project Summaries
   DC Safety: DC acts very differently from AC, so we need a whole new set of safety standards, education, and training so that people understand and
    implement DC safely.

   Explore DC appliances with speed control: Since variable speed is easy to do with DC motors, having DC in the building may allow the possibility of using
    many more DC motors for variable-speed applications. The economic advantages are greatest when there is a large number of DC motors or DC electronic
    loads that can all operate, or be easily adapted to operate, on the same DC voltage.

   UPS – PV integration (large or small): One of the things that could change with providing DC to data centers is the UPS system. It is likely that many data
    centers will convert to DC UPS systems. Solar PV systems, too, may supply DC directly rather than converting to AC and back again. Research is needed to
    determine how to most effectively do that.

   Research how much “stuff” in home is DC vs. AC at the core: Do some basic analysis to see if there is enough DC equipment in a typical home to justify
    having a DC supply in homes. It is unlikely that the load of DC in a home is enough to justify supplying DC.

   DC loss reduction – basic R&D: The concept of using DC power supply in a data center makes intuitive sense, but it is not well tested, especially in
    comparison to other approaches such as using higher AC supply voltage (230V.). Basic proof-of-concept and maybe some small trials are needed before
    expanding further.

   Power line carrier performance over DC lines: Power line carrier solutions for controls are attractive. Do some basic research to see if this is viable on DC
    systems; would likely need to avoid jumping AC-DC or DC-AC converters.

   Direct PV to DC equipment integration: Solar PV systems may supply DC directly rather than converting to AC and back again. This will be most effective if
    the voltage of the PV system is matched with the most common voltage needed by the DC equipment. Research is needed to determine how to most
    effectively do that.

   Data center requirements for DC only – underway @ EPRI: Since the idea of using DC for data centers is new, standards need to be developed before
    deploying widely.

   Universal plug adapter for DC – underway @ EPRI: One of the issues with converting to DC is that it is totally non-standard. The development of a universal
    plug for DC will greatly aid adoption.

   Higher voltage conversion AC as an alternative to DC (230v) – underway @ EPRI: As an alternative to converting data centers to DC, some researchers
    have suggested that we could save more energy by simply converting data centers to 230 V. The change would be simple and would require no equipment
    changes, since computer equipment is typically provided with a 115V/230V switch. Evaluate this thoroughly before committing to DC data centers.

R&D Project Summaries
   Improving information management: Perform a literature search to identify the manufacturers, national labs, and other organizations involved with R&D on
    information displays.

   Information synopsis for energy savings: Perform a literature search and primary research needed to identify potential energy savings by systems and
    software that automatically summarize lengthy documents for users.

   Ergonomic research on right-sized TV & computer displays: The trend in TV and computer displays seems to be "bigger is better," which increases energy
    use. Research "right-sized" displays.

   Visual performance impacts with micro-screens: Using smaller computer screens saves energy, but for some applications performance may be reduced
    such that this is not feasible. Research user feedback.

   Assess secondary research on state-of-the-art information displays: Perform a literature search to identify the manufacturers, national labs, and other
    organizations involved with R&D on information displays as a potential path to energy savings.

   More efficient server use: To greatly cut energy use for data center servers and cooling, research "virtualization," which increases the sharing of servers so
    fewer servers and power supplies are needed.

   User comfort with VR goggles @ MIT Media Lab: Virtual reality (VR) goggles can replace displays using much more energy, but research is needed on user
    comfort with VR goggles. Also examine the potential savings, comfort, and usability of miniaturized displays embedded in traditional eyeglass frames.

   Integrate cable, TV and phone to the internet: Using one appliance to do computing, cable TV, and phone could conceivably save energy. Research to
    examine the extent that that full function is maintained or improved would be useful.

   Optic nerve connect @ where?: Perform a literature search to identify the manufacturers, national labs, and other organizations involved with R&D on the
    broader use of optical data transfer, which is more energy efficient than metal cables.

   Network/web energy usage research leading to better awareness of energy use of Googling, e-mail, etc @ LBNL: Many users consider it environmentally
    benign to transfer info electronically rather than with paper, but there is substantial energy use for this; research this and raise user awareness. As a
    subtopic, perform a literature search to identify the manufacturers, national labs, and other organizations involved with R&D on the broader use of optical
    data transfer, which is more energy efficient than metal cables.

R&D Project Summaries
   No current mean time between failures (MTBF) testing, part of CEC CASE study (Title 24 goal for 2013): Need better information on the mean time
    between failures (MTBF) for different equipment in order to inform predictive maintenance programs and controls.

   Some research on neural networks, etc. not conclusive – need more algorithm development: More research on neural networks and artificial intelligence
    is needed to help inform design of self-healing and learning HVAC controls systems.

   Hardware is available; need more reliable fault detection (FDD) and diagnostics controls at smaller scale to drive market acceptance: Though hardware
    is available for sophisticated controls, more work is needed on software and thoughtful design and application of fault detection and diagnosis controls.

R&D Project Summaries
   Fault response on compressors related to US companies: One of the important areas to develop right now is self-diagnostic controls. An important aspect
    of that is to develop and implement fault response on compressors.

   Research to reduce maintenance @ WCEC, NIST, ETO: Reducing maintenance on energy-efficient equipment can help expedite uptake of the equipment.
    Downtime in itself can be wasteful and reduces service. Replacing equipment prematurely likewise increases embedded energy of equipment and reduces
    service.

   Air Conditioning Rx Sentinel @ CEC PIER field study: Developing and testing self-diagnostic controls for air conditioning will help increase reliability and
    efficiency of HVAC systems.

R&D Project Summaries
   Heat recovery optimization routines such that economizer performance is not impacted: Developing controls and system designs to optimize heat
    recovery and use of outside air can reduce or eliminate HVAC compressor and burner operation for many hours per year.

   Modularize grocery and supermarket waste-heat recovery for space and domestic water heating: Do a field study of using heat recovery from grocery
    refrigeration or air conditioning to use for space heating in other areas or to pre-heat domestic hot water.

   Reliability of enthalpy controls @ NBI: Good enthalpy control is important for efficient control of economizers. To date, enthalpy controls have been found to
    have notorious reliability issues. Developing and testing a reliable enthalpy control could help save significant energy in the Northwest.

   Condensing gas pack RTUs @ NRCAN, CEE: Roof-top units (RTUs) with condensing gas heat will be much more efficient than non-condensing. Field test as
    necessary and encourage implementation in the Northwest.

R&D Project Summaries
   Better mini-split controls with variable refrigerant flow (VRF) applications: VRF and other control optimization can make mini-splits even better
    alternatives to conventional central AC.

   More information about energy use; improve controls: Develop reliable engineering and technical information on how to optimize VRF energy savings while
    assuring comfort and reliability.

   Water-based VRF systems to incorporate geothermal with VRF: So much attention has been given to air-source heat pumps recently that the VRF "multi-
    split" and "mini-split" systems are nearly as efficient as ground-source and water-source heat pumps. Could we combine the technologies, using what we have
    learned in VRF technology to further increase the efficiency of water-source heat pumps?

   Field test variable speed heat pumps @ EPRI, URF, Daikin: One of the most promising heating and air conditioning technologies is variable refrigerant flow,
    or "multi-split" systems. However, good field testing is needed to verify that it can perform in the field as promised in theory.

R&D Project Summaries
   Drop-in electronically commutated motors (ECM) for residential applications: Use of ECMs for small motors could decrease energy use and increase ease
    of speed control significantly. A line of ECMs that would drop in easily for retrofit would make implementation easier and more widespread.

   Make electronically commutated motors bigger and compatible with belt-driven loads: ECMs have been very effective for saving energy and simplifying
    speed control for small motors. Having them available in larger sizes could simplify many retrofits, increase efficiency, and simplify design of variable speed
    systems.

R&D Project Summaries
   Need more accurate modeling to more easily compare systems: Building modeling for design has been a great boon to designing energy-efficient
    buildings, but there's much room for improvement. We should make it much easier to try out alternative scenarios without having to do detailed re-designing
    of the building model.

   Do field tests to compare building models to actual energy use; provide feedback in order to help develop more accurate building simulations: Do field
    tests to compare building model to actual energy use when built. Provide feedback to building modeling developers to help them develop more accurate
    building simulations.

   Field M&V test for zoning savings: Do some field tests to gather data for optimizing design choices for zoning with different heating and cooling systems.

   Develop load-based lab testing for RTUs (ASHRAE 1608-RTAR): ASHRAE is currently working on updating the testing standard for roof-top units; ASHRAE
    1608-RTAR. Once that is completed, implement the standard in the Northwest.

R&D Project Summaries
   Geothermal bore testing for different boring technology performance, integrating into the building structure: It would be worthwhile to have some good
    data on what kind of drilling is generally most cost-effective under certain conditions for geothermal heating and cooling systems. Test the different methods
    against each other for cost-effectiveness. If not already available, develop a best practices guide for what conditions favor which drilling techniques.

   More variability, determined automatically in simulation for more realistic systems modeling: Building modeling for design has been a great boon to
    designing energy-efficient buildings, but there is much room for improvement. We need to develop the capability to program in more variability for specific
    building conditions. Ideally, the program could anticipate some of the specific features. We should also make it much easier to try out alternative scenarios
    and perhaps to have modules that would automatically suggest options to optimize the design.

R&D Project Summaries
   Scan existing technology from cell phones for transformation to new uses with standardized wireless communication systems: Cell phones are now
    ubiquitous and versatile. Being able to send alarms to cell phones or even being able to change control settings via cell phone would add to the convenience
    of control systems and operators may pay more attention to them without being distracted from other tasks. Scan for current technology before developing
    new systems.

   Northwest Energy Technology Collaborative (NETC) is doing some work on power line carrier to distribute controls signals over low transmission voltage
    lines. Could this be used for commercial building voltages?: The attraction of power line carrier signals for controls is compelling. Power lines are available
    virtually wherever control is needed. This eliminates the need for installing an additional set of wires or more expensive wireless equipment. If barriers to
    implementing this in commercial applications could be removed, it could simplify and reduce the cost of installation of controls, especially for retrofit. Is NETC
    studying this?

   Federal stimulus-funded demonstration projects involving home energy management: One of the foci of the federal stimulus package was to foster energy
    efficiency by promoting and/or funding good home energy management. Action: Check to see what is underway for potential collaboration and check to see
    if more funding is available.

   Best Buy has Minnesota-based prototype testing and development, includes strategy for extension from current offering to electric vehicle wiring,
    home EMS, energy audits and services, smart phone applications, etc.: Having good tools and education available through easily-accessible sources such
    as local stores could be a big boon to the under-served residential energy management market.

R&D Project Summaries
   Review Existing (DOE, Smart grid R&D workshop): Some smart electric power measurement of facilities is already available. Before putting too many
    resources into research, it would be worthwhile to do a thorough assessment of tools and systems that are already available.

   Standards research @ NIST (Priority action group working on standards): Developing standards for measuring facility energy use would help simplify and
    standardize energy measurement. Work with NIST to help develop useful standards.

   Develop metrics for interval data. Related to significant drivers such as time of day, weather, etc., high/low ratios: The first step to analyzing energy use
    is good data. Developing standardized metrics will help make the information more accessible, and make it easier for more people to be able to analyze the
    data.

   Low cost, reliable enthalpy sensor @ NBI: A low-cost, reliable enthalpy sensor would help gather much needed information for energy analysis. NBI is in the
    process of developing or testing one.
