Title: Utility Analysis and Site Selection


1
  • Utility Analysis and Site Selection

2
Are the HUD Incentives My Best Option?
  • Function of many factors - evaluate
  • Long-term capital equipment replacement needs
  • Exceed available HUD capital funding?
  • Timeline
  • Level of need
  • Level of resident occupancy, comfort, and
    cooperation
  • Maintenance staffing and costs
  • REMEMBER - maintenance savings may be real, but
    cant be used to determine cost-effectiveness of
    the project under HUD rules.
  • Management staffing
  • Consistent use of the facility

3
Are the HUD Incentives My Best Option?
  • Can an Efficiency Program Self-Fund?
  • High Consumption?
  • High Rates?
  • Can you buy-down the project using
    Modernization Funds for non-energy/water
    components?
  • Investigating these questions can save you from
    going down dead end path
  • REMEMBER - You must be able to re-pay a loan from
    savings!

4
Utility Analysis
  • Do this before issuing RFP!
  • Tracking consumption makes this easier
  • Software to help
  • Reports to help with HUD reporting requirements
  • Graphics to visualize information
  • Units of consumption, not just dollars
  • By apartment, building, meter
  • ESCo will want this data
  • Aids in management and maintenance as well

5
Utility Analysis
  • Use your currently available data
  • Work with your utility to fill in gaps
  • Need tenant releases to get data on actual bills
    that are tenant paid
  • PUT THIS IN YOUR LEASE!
  • Provides means of ensuring allowances make tenant
    whole and conservation program savings arent
    borne on the back of the residents.
  • Directs measures and sites for consideration

6
Utility Analysis
  • Resources for crunching the numbers
  • Consultants
  • Past audits
  • In-House staff
  • Tracking software
  • ESCOs???
  • You want this determination before issuing RFP
  • Much of the work on HAs end - gathering data
  • Beware of obligating yourself at this stage of
    the game - fee-for-service only?

7
Benchmarking
  • How do your Sites Compare to Others?
  • Rough estimate
  • Weather Normalize
  • Heating Degree Days
  • Takes out climate as factor
  • Normalize for Square Footage

8
Benchmarking
  • Common Measures
  • /square foot
  • Btu/square foot/heating degree day
  • Gallons/day/resident
  • Btu/s.f./HDD normalizes for weather and for size
    of building
  • Still need to account for rates
  • 6 cents/kwh vs. 12 cents/kwh -gt two times the pot
    of savings for a given amount of consumption.

9
Benchmarking
  • Can help you ID best candidates within your
    portfolio
  • Phased RFP
  • May leave some out altogether
  • Dont waste your time and the ESCos by pursuing
    sites that wont yield a cost-effective,
    self-funding conservation program

10
Evolution of Selected Sites through Performance
Contracts
  • Developments are identified by the PHA in the RFP
  • Phased, with option to expand
  • Based on utility analysis, building use and
    capital needs
  • Measures are screened and proposed by ESCOs in
    the audit
  • 2 phase audit report
  • Proposed measures are evaluated by the PHA
  • Measure design installation is performed by
    ESCO under an ESA

11
Site Selection for RFP
  • ID your desires and needs
  • Look at the realities of
  • level of consumption
  • level of rates
  • cost of capital
  • occupancy rate
  • long-range plans for the site
  • other available funds
  • BE FLEXIBLE - Be open to the ESCOs suggestions
    during the bidding and audit processes

12
Where to Look for Savings
  • In the Midwest, New England, and other heating
    climates, typical PHA Candidate Developments for
    Energy Performance Contracts have high historic
    utility consumption or cost patterns for
  • Heating
  • Domestic hot water production
  • Common area lighting electric loads
  • Domestic water use

13
Where to Look for Savings
  • In the cooling climates, typical PHA Candidate
    Developments for Energy Performance Contracts
    have high historic utility consumption or cost
    patterns for
  • Domestic hot water production
  • Common area lighting electric loads
  • Domestic water use
  • Cooling Savings
  • Normalizing for Cooling Degree Days not allowed
    by HUD
  • Issue - who pays the bill? Can HA recover
    cooling savings?
  • 24 CFR 965.506(e)

14
Information to Provide in an RFP
  • See Sample Technical Section for RFP in
    Resource Guide
  • Include, by building, meter or complex
  • Utility monthly use and cost over three years
  • Name of facility
  • Number of dwelling units
  • Occupancy levels
  • Family or elderly residence
  • Rough description of construction and systems

15
Best Candidate Types
  • Master metered for all utilities, multiple
    buildings
  • Can do tenant paid, with waiver
  • Adds complications to savings calculations
  • Has not received modernization in over 10 years

16
Basic Site Types to Include
  • 1940s vintage with central space heating/domestic
    hot water plants
  • All-electric high/mid-rises in climates with
    annual 5000 HDDs and 0.08 kWh
  • Newer vintage townhouse style, individual heat
    and DHW can be done
  • 1 year old buildings with 100 year old problems
  • Base choice on results of utility analysis and
    rough estimate of cost of measure!

17
Basic Site Types NOT to Include
  • Scattered sites single detached houses or
    duplexes in clusters of one to one dozen
  • Challenge is in getting consistent performance
    and documented savings at all houses

18
Other Factors to Consider
  • Scheduled heating/cooling/DHW/distribution system
    replacement
  • Mechanical systems with high maintenance,
    operational costs
  • Necessary window replacements
  • Virtually never are cost-effective from
    energy-savings standpoint alone!
  • Equipment measures and/or appliances scheduled
    for replacement in PHA's Five Year CGP Plan

19
Other Factors to Consider
  • Developments expected to remain under PHA
    management for at least the next decade
  • Developments and measures with a rich savings
    stream supported by relatively low cost
    investments
  • Bundling opportunities for maximum leverage of
    capital improvements
  • Developments with central laundries
  • Other criteria articulated by PHA personnel

20
Audit Phase
  • Monthly utility use histories and account
    numbers actual copies of bills important
  • Previously implemented energy-related
    modernization plans and dates of implementation
  • Previously completed energy audits and surveys
  • Capital needs assessment reports

21
Audit Phase
  • Require ESCO to
  • 1. Develop baseline for each utility, per HUD
    requirements
  • 2. Perform end use disaggregation of utilties
  • 3. Normalize data
  • 4. Establish savings projections in relation to
    base years
  • 5. Evaluate in-pocket savings vs. HUD savings

22
Before Any Measures May Be Formally Screened by
the ESCO, the ESCO Must
  • Evaluate the quality of the data
  • Clean it
  • Analyze it by End Use
  • End Use Disaggregation must be performed by an
    energy engineer or conservation professional.

23
Energy and/or Water Baseline Consumption
  • The Baseline is the ESCOs assessment of the
    pre-retrofit utility consumption and cost.
  • It must be approved by HUD.
  • Based on Rolling Base, and/or
  • Reviewed Utility Allowances
  • It provides the basis for
  • ESCO savings projections and measure screening
  • Calculation and payment for actual savings
    achieved

24
Water Data for A Client Housing Authority
  • Four developments
  • 1. Riverview family development, 180 dwelling
    units in 45 quads, walk-ups
  • 2. OBrien Towers elderly development, 275
    dwelling units in one mid-rise building (six
    stories)
  • 3. Pagnano Towers elderly development, 156
    dwelling units in one high-rise building (15
    stories)
  • 4. Drohan Apartments elderly development, 40
    units in one low-rise building (three stories)

25
Utility Data in PHAs RFP included Energy
Consumption and Costs, by Site, per Month
  • In Audit Phase, ESCo retrieved data directly from
    the utilities
  • Computer printouts containing monthly use and
    cost information
  • Paid data entry clerks to put utility
    information in Excel files
  • They were able to analyze the utility data and
    form the BASELINE

26
Quincy Water Measures
  • Riverview none
  • OBrien New water closets, new faucet aerators,
    showerheads
  • Pagnano New water closets, repair leaks, new
    faucet aerators, showerheads
  • Drohan New water closets, new faucet aerators,
    showerheads

27
Re-Cap of Steps for Utility Analysis
  • Gather readily available utility data on
    consumption and cost on site-by-site basis
  • 3 years is best, and will be needed for the ESCo
    to establish baseline for HUD
  • Determine if gaps exist and impacts of these gaps
  • Work to gather remaining data if appropriate
  • Look at changes in occupancy, use or equipment
    during the period youre evaluating

28
Re-Cap of Steps for Utility Analysis
  • Understand how your PHA is processing the
    utility bills and reporting the usage to HUD
  • make changes in tracking procedures if needed
  • Tabulate your gathered utility data in total
    and on site-by-site basis
  • Calculate portfolio-wide average
  • Calculate averages for each development
  • Compare the developments with the portfolio
    average and other benchmarks
  • This will help you to identify the outliers
    family sites, elderly sites, high-rise vs.
    walk-ups
