Energy Background
  • Rising Costs Price Volatility
  • Fuel Supplies Less Reliable
  • Weather Concerns
  • Instability in Oil Producing Nations
  • High Demand
  • Greenhouse Gas Issues

Managing Your (Rising) Energy Costs
  • Energy Costs have risen dramatically over the
    past couple of years
  • Commodity Pricing (without transmission charges)
  • Crude Oil NYMEX Crude Futures around 67/bbl
    for January 2006 delivery. Average prices for
    2001 were around 22/bbl
  • Natural Gas NYMEX Futures around 12.50/MMBtu
    (1.25 per therm) for October delivery. Average
    industrial user pricing for 2001 was 5.1/ MMBtu
    (0.51/therm) and 3.91/MMBtu (0.39/therm) for

Future Energy Pricing Uncertain
  • Forecasts for the near term future are trending
  • Tight refinery capacity makes it difficult to
    predict the next event that could impact pricing
  • Rising energy costs erode profits for companies

Risks to Crude Supply
  • Approximately 2.4 million Barrels per day or 24
    of imported crude oil comes from the Persian Gulf
  • Venezuela and Nigeria produced approximately 2.4
    million barrels per day or 24 of imported crude
  • Nearly 48 of imported crude comes from regions
    of risk due to political instability

Refinery Capacity
  • World Demand is at an all-time high due to
    economic growth over the past couple of decades
  • US demand is at all time high. Lack of
    investment in new refinery capacity has caused
    production bottleneck
  • Hurricanes - Katrina Rita have highlighted the
    risks to Gulf of Mexico Production and Refining

Natural Gas Imports/Exports
  • In 2004, approximately 15 of US gas consumption
    was from imports, mostly from Canada.
  • Demand for natural gas is increasing beyond North
    American production rates, so LNG imports are
    growing. Trinidad, Algeria, Qatar and Nigeria
    provided 95 of LNG imports from 2000-2004.
  • Continued increases in demand will tax the
    capacity of transcontinental pipelines, requiring
    increased LNG imports to meet demand in
    northeastern US.

So here we are
  • Todays energy crisis is different than that of
    the mid 1970s, which turned out to be a short
    term event.
  • Increased demand for crude oil and natural gas
    will be met by foreign sources
  • US continues to lack a comprehensive energy
    strategy to reduce dependence on foreign
    supplies, therefore
  • Reliability and pricing concerns of our energy
    supply will likely be with us for the long haul
  • So what can you do about it?

Before you get started
  • Get upper management involved. You cannot
    succeed without senior management support for an
    energy reduction program (formal program that has
    targets in senior management objectives
    Novartis recently signed off on Kyoto Protocol
    5 reduction in greenhouse gases from 1990 levels
    by 2008 2012)
  • Collaborate with others in your industry. This
    will allow you to take advantage of the ideas and
    lessons learned by others. (PMON, NJPFEUG,
  • Engage different user groups (maintenance,
    manufacturing, environmental, others) on site to
    brainstorm opportunities. This is especially
    important for sites where manufacturing
    operations are energy intensive.

Before you get started
  • There are many resources to help you develop your
    plan. Two good resources are
  • Energy Star (
  • US Department of Energy Energy Efficiency and
    Renewable Energy (http//
  • Both websites have good information on strategies
    and case studies to learn from
  • If you lack the resources, time or expertise,
    consider engaging a consultant with expertise in
    energy reduction programs

Energy Star Steps for Energy Reduction Program
  • Make a Commitment - Organizations seeing the
    financial returns from superior energy management
    continuously strive to improve their energy
    performance. Their success is based on regularly
    assessing energy performance and implementing
    steps to increase energy efficiency.
  • Assess Performance - Understanding current and
    past energy use is how many organizations
    identify opportunities to improve energy
    performance and gain financial benefits.

Source Energy Star Website (http//energystar.go
Energy Star Steps for Energy Reduction Program
  • Set Goals - Performance goals drive energy
    management activities and promote continuous
    improvement. Setting clear and measurable goals
    is critical for understanding intended results,
    developing effective strategies, and reaping
    financial gains.
  • Create Action Plan - With goals in place, your
    organization is now poised to develop a roadmap
    to improve energy performance.

Source Energy Star Website (http//energystar.go
Energy Star Steps for Energy Reduction Program
  • Implement Action Plan - People can make or break
    an energy program. Gaining the support and
    cooperation of key people at different levels
    within the organization is an important factor
    for successful implementation of the action plan
    in many organizations.
  • Evaluate Progress - Evaluating progress includes
    formal review of both energy use data and the
    activities carried out as part of the action plan
    as compared to your performance goals.

Energy Star Steps for Energy Reduction Program
  • Recognize Achievement - Providing and seeking
    recognition for energy management achievements is
    a proven step for sustaining momentum and support
    for your program. (Novartis uses HSE success
    stories and Energy Awards.)
  • Reassess As you move forward with your plan,
    changes in your site or the energy marketplace
    should be considered, and adjustments made to
    your plan to keep it appropriate.

start with how your facilities are currently
  • Collect data on consumption utility company
    bills, internal distribution metering. Look at
    the past couple of years to determine trends and
    identify areas of opportunity. Tracking will be
    important to identify opportunities, establish a
    base case for financial analysis of energy
    opportunities and verify savings, identify
    metering deficiencies early and how information
    should be presented early on.
  • Many facilities have sophisticated Building
    Management Systems that could be better utilized
    to reduce energy consumption. System integrators
    are typically not tasked to provide optimal
    operating programming up front, and, over time
    individuals may have altered programming for
    convenience. Take a systematic approach, as each
    opportunity arises, see where else it can be
    applied in a campus environment.

start with how your facilities are currently
  • Maintenance of systems properly maintained
    systems utilize less energy to perform the same
  • Look at your Building Management Systems
  • Check space temperature setpoints. Verify that
    they are acceptable. Adjust as required to
    reduce energy consumption while maintaining
  • Check calibration of key parameters like outside
    and interior temperature sensors. Also check
    flow meters and differential pressure sensors
    where a central chiller plant is supplying
  • Verify that time of day/week occupied/unoccupied
    settings are correct and functional
  • Optimize start/stop of systems

start with how your facilities are currently
  • Make sure that you change HVAC filters regularly
    added pressure drop increase to fan energy.
    Novartis has standardized on an extended bag
    filter that fits most air handlers, reducing
    change-out frequency and pressure drop
  • Perform vibration analysis on all equipment 5 HP
    and above (less for critical systems). Novartis
    performs this as part of commissioning to avoid
    inheriting problems, and routinely so as to shift
    from preventative to predictive maintenance.
    Before / after repair testing demonstrates energy
  • Evaluate chiller plants, compressed air systems
    and boilers using third parties specializing in
    these systems.

Start with the biggest users of energy
your buildings
  • Determine where your buildings are operating
    relative to similar buildings. Energy Star
    Portfolio Manager can help, however labs and
    manufacturing buildings have not been
    benchmarked. Labs 21 (http//www.labs21century.go
    v/toolkit/benchmarking.htm) can help with
    laboratories and clean rooms
  • Use auditing tools to identify opportunities to
    improve energy performance
  • Take care not to delay starting obvious
    initiatives (maintenance, BMS system adjustment)
    while waiting for a comprehensive review, which
    may take up to a year depending on the size of
    your facility.

Look at your Building Management Systems
  • Check space temperature setpoints. Verify that
    they are acceptable. Adjust as required to
    reduce energy consumption while maintaining
  • Verify that time of day/week occupied/unoccupied
    settings are correct and functional. Utilize
    intelligent programs to start/stop and sequence

Facility Renovations, Expansions and Contraction
  • In the past, projects were performed only
    considering the additional energy needs of the
  • Where it makes sense, larger projects can provide
    a good opportunity to increase the energy
    effectiveness of a facility. Increases to
    on-site energy generation can be considered to
    meet capacity and increase efficiency.
  • Architectural Masterplans should be complemented
    with an Energy Master Plan. The Energy
    Masterplan should maximize the return on
    investment of systems utilizing energy.
    Lifecycle costing of systems should be performed
    to verify the true low cost system. Novartis is
    performing energy modeling of new facilities.
  • Some sites are reducing the number of buildings
    or changing from manufacturing to office,
    lowering energy demand. This can lead to
    oversized and potentially inefficient on site
    energy plants. Novartis recently reduced energy
    consumption by converting old labs and
    manufacturing space to office space.

Energy Reduction Program
  • Take advantage of rebates to buy more efficient
    equipment in your construction projects.
  • Replace older, less efficient equipment.
  • Look at replacement options like for like
    replacement may not improve efficiency as much as
    technology change.
  • Upgrade controls and sequence of operations
  • Take advantage of incentive s for renovation
    and new projects NJ Smart Start Program

  • Manufacturing processes tend to be very energy
    intensive. There may be an opportunity to shift
    work to have more energy intensive operations on
    off-hours with lower electric rate
  • Work with representatives of manufacturing to
    identify opportunities to reduce energy usage.
    They will resist, so be prepared to encourage
    them with potential energy savings
  • Minimize air exchange rates. Novartis has been
    able to reduce air exchange rates in pilot plants
    and lab buildings by carefully considering
    requirements and working with all stakeholders
    well in advance.

Site Energy Generation
  • Once you have look at your buildings, focus on
    your on site energy generation
  • Boiler Plant
  • Chiller Plant
  • Compressed Air Plant
  • Cogeneration
  • Tools for Maximizing Plant Efficiency

Boiler Plants
  • Regularly test boiler efficiency tune and
    adjust to maximize efficiency
  • Tune boilers to specified excess air levels.
    Utilize O2 trim control where possible
  • Consider back pressure turbines for reducing
    pressures for larger quantities of steam
  • Evaluate flue gas economizer and blowdown heat
  • Evaluate water treatment program bad water
    treatment reduces heat transfer efficiency
  • Load matching operate at best efficiency point
  • Replace oversized equipment with appropriate
    boiler sizing to avoid unnecessary cycling and
    low load operation
  • Multi-fuel capability also consider alternate
    renewable fuels (like biofuels)
  • Steam Trap Maintenance
  • Verify that steam traps are operating properly,
    repair or replace malfunctioning traps.
  • Consider remote monitoring capability
  • Novartis commissioned a steam trap survey which
    identified 5 of traps at the East Hanover site
    were plugged or passing steam (industry average
    is around 10). The energy savings more than
    offset the repairs and the cost of the survey

Existing Chiller Plants
  • Utilize controls system to optimize operation of
  • Base load most efficient units
  • Consider replacement of older, less efficient
  • Consider diversification of fuels, with a mix of
    electric, steam (absorption or turbine) and gas
    fired to hedge against changes in fuel costs and
    to avoid time of day and demand charges
  • Employ some metrics to determine if chiller plant
    is running optimally throughout the cooling
    season, and to direct maintenance activities in
    the winter months. GE Betz offers a program
    called Chiller Check for a fee.

New Chiller Plants
  • Do not oversize the plant unnecessarily.
    Operating chillers at partial load can reduce
    efficiency. Select module sizes to maximize
    loading based on anticipated load profiles, while
    also considering redundancy
  • Consider diversification of fuels, with a mix of
    electric, steam (absorption or turbine) and/or
    gas fired absorption to hedge against changes in
    fuel costs and to avoid time of day and demand
  • Consider the use of heat machines, or comparable
    equipment, to take waste heat from the condenser
    and utilize it for free heating in reheat or
    other lower temperature systems
  • Consider the use of thermal storage systems to
    reduce plant size. This strategy will minimize
    time of day and demand charges.
  • Optimize your chilled water distribution system
    to minimize pumping costs
  • Utilize VFD control for chillers, pumps and
    cooling tower fans
  • Utilize controls system to optimize operation of
  • Base load most efficient units

Compressed Air Systems
  • Compressed air systems - Assess the efficiency of
    the compressed air plant. Older plants that have
    been incrementally enlarged may operate
    inefficiently. Consider strategies to address
  • Compressors controlled from a central controller
    to maximize efficiency
  • Enlarging the compressed air receiver to reduce
    run time for compressors
  • Pressure and demand matching
  • Perform regular inspections of system to verify
    the leakage is minimized. When possible, add
    manual and/or automated valves to shut off air
    flow when user equipment is shut-off. This is
    particularly important with packaging equipment
  • Interconnecting separated systems, where
    possible, to minimize the number of compressors
    required to operate
  • As with all other systems good maintenance will
    go a long way to improving performance of the

Optimize Utilization of On Site Generation Assets
  • Model each on-site utility generation system to
    develop operating scenarios that maximize plant
  • Know the implications of changes to fuel prices
    on selection of generation equipment to run
  • Weather plays a part non-process HVAC loads are
    typically proportional to outside temperature.
    This may allow you to model your systems as a
    function of outdoor conditions giving operators
    the most efficient operating configuration in

Buying Your Energy
  • Strategies Buy your energy smarter
  • Bid energy contracts beware of entering into
    long-term contracts at peak price points
  • Take advantage of buying power. Aggregate your
    facilities to buy energy in larger quantities to
    reduce price.
  • Be part of an energy buying consortium to buy
    energy with others, particularly if you dont
    have an energy manager tracking the market
  • Consider longer term buying horizon to gain some
    surety of pricing. Novartis is working toward a
    24 month rolling buying horizon.

Facility Audits and Benchmarking
  • Strategies Audit and Benchmark Your Facilities
  • Use auditing tools from Energy Star, DOE, AEE, or
    other reputable source.
  • Start with big users of energy first.
  • Involve manufacturing and environmental
    compliance representatives
  • Make sure you find all big users of energy.
    Items like thermal oxidizers can use large
    quantities of energy

Facility Audits and Benchmarking
  • Once you know where you are develop goals for
    where you want to be, along with a road map for
    getting there.
  • Goals should be achievable and in concert with
    corporate priorities. Timelines must be
    monitored and long term goals adjusted to reflect
    changes in energy use patterns, energy costs and
    changing corporate priorities.
  • Many large companies already have corporate goals
    for energy conservation and emissions reductions.
  • JJ - greenhouse gas emissions 4 reduction
    by 2005 and a 7 reduction by 2010, in absolute
    terms with 1990 as a base year.1
  • Novartis The Group has adopted energy-
    efficiency targets for 200406, calling for each
    business unit to improve energy efficiency by 2
    a year. Half of this reduction, 1 of annual
    consumption, should come from concrete
    energy-saving projects.2 Novartis recently
    signed the Kyoto Protocol thereby committing to
    reducing the companys GHG emissions 5 below
    1990 levels in the time period 2008 - 2012

Solar Renewable Energy Credits (SREC)
  • NJs Renewable Portfolio Standard (RPS) requires
    electricity suppliers provide a percentage of
    their electricity sales from solar generation.
  • 1 SREC 1000 kWh of power generated by solar
  • You can sell SRECs through NJ SREC Program
  • Values have been averaging between 160 - 178
    per MWh since August 2004
  • ex. 100kW system operating an average of 10
    hours per day for 250 days per year with SREC
    160/MWh (0.16/kWh) would generate SREC sales of
    40,000 per year
