Title: Utility Analysis and Site Selection
1- Utility Analysis and Site Selection
2Are 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
3Are 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!
4Utility 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
5Utility 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
6Utility 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?
7Benchmarking
- How do your Sites Compare to Others?
- Rough estimate
- Weather Normalize
- Heating Degree Days
- Takes out climate as factor
- Normalize for Square Footage
8Benchmarking
- 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.
9Benchmarking
- 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
10Evolution 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
11Site 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
12Where 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
13Where 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)
14Information 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
15Best 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
16Basic 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!
17Basic 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
18Other 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
19Other 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
20Audit 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
21Audit 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
22Before 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.
23Energy 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
24Water 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)
25Utility 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
26Quincy 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
27Re-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
28Re-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
