To arrive at that systematization, we have to defi ne each single step with
respect to
Stock data ■
Measured data ■
Performance metrics/evaluation techniques ■
Outcomes/aims of the step ■
Table 2 gives an overview of the details of the four-step procedure. Details
are given in the Work Package 3 (edited by C. Neumann) report of the IEE
project Building EQ (“Building EQ: Tools and methods for linking EPBD and
continuous commissioning,” at www.buildingeq-online.net).
TABLE 2. OVERVIEW OF THE FOUR-STEP PROCEDURE.
Step 1 Step 2 Step 3 Step 4
Simple Benchmark Certifi cation +
data acquisition FDD + Optimization Regular Inspection
Description Gather basic consump-
tion and stock data
and fi rst classifi cation
/ baseline of the build-
ing performance Certifi cation
according to
national imple-
mentation of
the EPBD Analysis of the building per-
formance, identifi cation and
implementation of energy
conservation measures, and
optimization of performance Maintain optimized
performance by
ongoing (minimal)
monitoring
Stock data Minimal building de-
scription Depending on
national imple-
mentation Additional stock data ac-
cording to individual needs No additional stock
data needed
Measured data Utility bills/own me-
ter readings (yearly/
monthly) Minimal data
set according to
Workpaper WP3 Additional measurements
according to individual
needs Reduce to
minimum
Performance metrics
evaluation techniques Benchmarks/signa-
tures Depending on
national imple-
mentation Evaluation: visualization,
statistical analysis, model-
based approaches
Metrics: to be developed
Energy consump-
tion as major
metric
Further actions None Installation of
data acquisition
(hourly data) Implementation of energy
conservation measures None
Outcomes First classifi cation +
baseline (y/m) Certifi cate
Theoretical
benchmark (AR)
Hourly data
available
Faultless/optimized operation
Energy conservation mea-
sures introduced
Documentation of energy
savings
Persistence of
