Glossary of building diagnostics

Alphabetical list of all technical terms related to building diagnostics in eTASK.

A

Client (AG)
Company or organization that commissions the diagnosis. Is recorded as a company (client).

Contractor (AN)
Company or person performing the diagnosis. Recorded as a company (Contractor).

B

Construction Cost Index (BKI)
Indices for converting diagnostic points into €:

• BKI Switzerland 2005: Fixed value 1.805 (reference value for IPBau method)

• BKI Germany (base 2010): Variable, recorded as an integer (e.g., 167)

• Conversion CHF → EUR: Fixed value 0.645 (as of 2005)

Comments
Free-text field in diagnostic points for documenting special features.

Rated points
See: Repair needs

Rating codes (IPBau a–d)
Four condition levels for rating:

Rating
See: Geometric coefficient. Recorded on the building as a KPI.

Budget
project Project created automatically from a diagnosis. Contains budget items with annual planning.

C

Repair Code
Condition assessment of an element. Includes diagnostic points, service life, and description of measures.

Improvement Code
Optional improvement measure (e.g., energy-efficient renovation). Includes additional diagnostic points.

D

Diagnosis
Date Date on which the diagnosis was performed.

Diagnostic Profile
Preselection of elements by building type (e.g., office building, residential building). Facilitates data entry.

Diagnostic Point
Assessment of a single element in the diagnosis.

Diagnostic
Points Point value from Code Repair or Code Improvement. Basis for cost calculation.

Diagnosis Type
Categorization of the diagnosis (e.g., "Initial Diagnosis," "Follow-up Diagnosis").

Diagnostician
Person who performs the diagnosis. Recorded as a diagnostician (employee).

E

Element
Structural element of a building (e.g., "exterior facade," "roof," "heating system").

Element
Group Supergroup of elements (e.g., "Building envelope," "Building services," "Interior finishing," "Outdoor facilities").

Element type
: A subgroup of an element (e.g., "exposed concrete," "composite thermal insulation system," "clinker").

Replacement
Year: The year in which an element is expected to require renovation:

Ersatzjahr = Aktuelles Jahr + Lebensdauer

Specified as Min and Max.

F

Factor
Weighting for sub-evaluations of an element (default: 1.0). Used when an element cannot be evaluated uniformly or exists in different types. Indicates the estimated percentage share of the total element (e.g., 0.1 for a 10% extension, 0.9 for a 90% main building).

G

Building Diagnosis
Systematic assessment of a building’s structural condition.

Geometric coefficient
Quantitative specification of an element (e.g., facade area in m², number of residential units). Recorded as an assessment value for the building.

Weighted points
Product of diagnostic points (base points), factor, and geometric coefficient:

Gewichtete Punkte = Basis-Punkte × Faktor × Geometrischer Koeffizient

I

Repair
Measures to restore an element to a functional condition.

Repair requirement: The cost of
renovation calculated in euros.

Formula:

Kosten (€) = Gewichtete Punkte × 1,805 × 0,645 × (BKI_D / 100) × Schwierigkeitsgrad

Where:

Gewichtete Punkte = Basis-Punkte × Faktor × Geometrischer Koeffizient

Repair code
See: Repair code

K

Difficulty coefficient
See: Difficulty level

KPI
See: Geometric coefficient

L

Service
life: Period in years during which an element is expected to remain usable. Specified as Min and Max in the Repair Code.

M

Measurement
Description of the required work. Included in Code Maintenance and Code Improvement.

Multi-Year Planning
Distribution of measures and costs over several years based on replacement cycles.

P

Points
See: Diagnostic points

S

Case Manager (AG)
Responsible person on the client side.

Difficulty
Level Parameter at the diagnostic level for building-specific challenges (default: 1.0). Recorded in the diagnostic header:

• 0.8–0.9 = favorable (standard construction, small buildings, good accessibility)

• 1.0–1.2 = normal

• 1.3–1.5 = difficult (old buildings, historic preservation, downtown location)

Master data
Basic data for the building diagnosis:

• Element areas, elements, element types

• Repair codes, improvement codes

• Diagnosis profiles, diagnosis types

Must be available before performing the diagnosis.

U

2005
conversion rate of 0.645 for converting Swiss francs to euros (as of 2005). Part of the calculation formula.

V

Improvement
Measures to optimize an element beyond its original state (e.g., energy efficiency improvement). Can be entered optionally using the Improvement code.

Improvement code
See: Improvement code

Z

Time Horizon
Period during which an element is expected to require renovation. Based on the calculated replacement years.

Short-term 0–5 years / Long-term >20 years

Condition
Current structural condition of an element. Recorded by selecting the "Repair" code (IPBau codes a-d).

Condition Level
See: Assessment Codes (IPBau a–d)
