Setting the Scene

• Indoor pollution is resulting from buildingmaterials– Asbestos used as fire proof insulation

– Polychlorinated Biphenyls (PCB) used in elasticseals, mainly between concrete parts

– Polyarmatic Hydrocarbons (PAH) used in adhesives and elastic seals in floors

– Pesticides (i.a. HCH) used as wood protectives

Example PCB

• Chlorinated hydrocarbons

• Group of 211 congeners

• Used in elastic material

• Used in many prefabricated concretebuildings, mainly in seals

• Fire resistant, very stable

• Widely applicated in the 1960s till 1980s

Toxicology

• Neuro-patholotical effects

• Oxidative stress by degradation products

• Contain dioxins and furans due to synthesisbyproducts these are ultimative cancerinducing substances

Regulations

• Usage in open systems banned in 1973

• Production banned in 1993, small amounts(condensors) allowed until 2010

• Part of the Rotterdam Convention(„The dirty dozen“)

• Rubble < 50 mg/kg

• PCB directives on state- but not on federallevel, slight differences from state to state

Regulatory Limits

<300 µg/m³ (approx 10% tolerable daily intake TDI)

No Adverse Effect Level

300-3000 µg/m³Observation Level

Source Removal, if AppropriateAir Management

3000 µg/m³ (approx TDI within 24 h)

Immediate Action Required

Current solutions

• Excel Sheets

• Access Databases

• Usually static reports to stakeholders

• Static Webpages

Ontology Development

Map of Site

Map of Floor with Measured Values

Latest Measurements Display

Definition of Measuring Values and Limits

Background information on substance

Summary

• Approach for displaying any semantic dataon related to images (i.a. floor plan etc)

• Display filtered to current values

• Correct display of– Measurands

– Measurement units

– Measured values

– Limit values

Room for improvement

• Color definition of image annotation bysemantic properties

• Integration of IFC/CAD-import for buildingdata

• Enhancement of Navigation
