RTF Meeting January 23, 2013 Kevin Smit 425-889-2700 x247 RTF
Costs and Benefits Standard Information Workbook A registered
professional engineering corporation with offices in the Seattle
and Portland metropolitan areas Telephone (425) 889-2700 Facsimile
(425) 889-2725 Consulting EES Slide 2 Standard Information Workbook
(SIW) 2 Objective: To develop regionally representative costs and
non-energy benefit data that are common across multiple measures
These costs are recorded and documented in the SIW (Excel Workbook)
Can be used as a common resource (and repository) for those
developing new or revised measures Provide a consistent platform
for cost data and analysis Provides automatic conversion from
data-year dollars to base-year dollars using Councils GDP deflator
Slide 3 Progression of SIW 3 Contract awarded in August, 2012 EES
continually contacted sources and collated data RTF staff met with
EES several times between August and November to walk through
approach and review draft versions of SIW Numerous rounds of RTF
Staff review for workbook structure, data sources, analysis
methodology, and content Presenting to RTF to gain feedback before
adopting to use across multiple measures Slide 4 SIW Contents 4

Slide 8 RTF Cost Guidelines 8 Reference: Guidelines for the
Development and Maintenance of Incremental Measure Costs and
Benefits Estimates (March 2012) The guidelines recommend the
following estimation approaches and one or more of these were used
in each of the worksheets: 1. Averages (arithmetic mean) 2.
Weighted average 3. Median 4. Regression modeling 5. Lower quartile
6. Built-up cost estimates Slide 9 CFL Prices 9 Excluding Discounts

Slide 12 SF Windows 12 Estimation Method: Lower quartile approach,
same as before Source: Energy Trust database (N=2800) Issue: There
is little or no cost data for the baseline window (U35). Currently
using U34 window from Lowes plus installation (Total=$21.55/sf).

Method: Median installed cost per square foot, same as before
Source: Energy Trust database (N=82) Issue: New MF values use same
upgrade assumptions and costs as SF. Impact: replacement costs are
lower, upgrade costs are higher. MeasureCost ($/sf in

Method: Single family job cost based on Median value of utility
data set. Source: Energy Trust data set (N=2800) Issue: Multifamily
job cost is based on the incentive level ($300). Actual costs are
not recorded, but most jobs are performed for the incented amount.

commissioning cost ($225 in 2012$) Issue: Sizing is based on the

approach as existing workbook) ComponentCost Per Job

Estimation Method: Regression analysis of retail units (Lowes, Home
Depot, Sears). Source: Retail price sheets Issue: Initially tried
regression analysis of a utility data set, but R Square was very
low. Impact: Costs are lower than current workbook. MeasureInc.
