Diagnosis and treatment

Sick buildings

MAC

The maximally allowed concentration (MAC) of a gaseous substance is that concentration in the air of a working environment that in general

  • According to current knowledge;

  • Even at repeated and long-term exposure;

  • During the full working life;

    will not harm the health of workers nor that of their descendants

    [Nationale MAC-commissie 1978]

MAC-TGG= tijdgewogen gemiddelde / time weighted mean

MAC-C = peak concentration

Health damage buildings

Health damage & buildings

  • Sick building syndrome (SBS) = occupants experience acute health and comfort effects that are linked to time spent in a building; no specific illness or cause can be identified

  • Building related illness (BRI) = occupant shows symptoms of diagnosable illness that can be attributed directly to airborne building contaminants

Additive effects

Additive effects

Example: Pollution by a Laser printer

C = Concentration in the Air;

MAC = MAC value:

Ozon: 0.1 ppm; Carbon monoxide: 25 ppm; airborne dust (stof) 0.05 mg / m3 air

Sick buildings

  • A Sick Building

  • forms an environment that adheres to relevant standards but does not fully answer to the human need for:

  • - Absence ofPathogens

  • - Absence of other biotic, chemical or physicalPollutants

  • - ThermalComfort

  • LightingComfort

  • AcousticComfort

  • - SufficientSpace, Privacy, Peace and Quiet

  • Contactwith outdoors (view, sound, smell, air quality)

Sick buildings

A Healthy Building

forms an environment that

- Has a Low Risk for negative health effects

- Makes Healthy Behaviour self-evident

- Compensates for disease or infirmity present

- Stimulates users to realise their ambitions

- Leaves Users Master of the situation

Building Assessment

Building-in-use method = repeated questionnaires

JEMH van Bronswijk TU/e


General measurements

“General” measurements

  • Carbon dioxide

  • Carbon monoxide

  • Water vapour

  • Airborne dust

  • Pay attention to the following:

  • Peak values may be more important than averages

  • Measure continuously for 7-10 days

  • Measure outdoor and indoor concurrently

  • Combine physical values with a complaint diary

Building services design also for dwellings

Building services design(also for dwellings)

  • Robust

  • Locus of control = user

  • Automated when desired by user

  • Sensors for CO, CO2, energy use, ….

  • Automated safety actions always with explanation to the users

  • Action options for the user
