Abstract

Electromagnetic fields (EMF) permeate the built environment in different forms and come from a number of sources including electrical wiring and devices, wireless communication, 'energy-efficient' lighting, and appliances. It can be present in the indoor environment directly from indoor sources, or can be transmitted through building materials from outside sources. Scientists have identified it as an indoor environmental pollutant or toxin that has ubiquitously plagued developed nations causing a variety of adverse health effects such as sick-building syndrome symptoms, asthma, diabetes, multiple sclerosis, leukemia, electro-hypersensitivity (EHS), behavior disorders, and more. There is currently no international consensus on guidelines and exposure limits. This paper presents the results of 29 EMF field audits in single family residential dwellings located within an urban neighborhood in Toronto (Canada). The following EMF spectra were evaluated: radio frequency, power frequency electric fields, power frequency magnetic fields and high frequency voltage transients. The field audits were conducted in order to provide initial baseline statistics to be used in future studies and in order to be compared to a low-cost EMF reduction design incorporated within the Renovation2050 research house - located within the test neighborhood. The results show the low-cost reduction strategy to be effective, on average reducing exposure by 80% for high-intensity EMF metrics. Research of this nature has not been conducted with relation to the built environment and can be used to spark an industry movement to design for low-exposure to EMF in a residential context.

Main findings

The paper reports results from 29 EMF field audits in single-family homes in an urban Toronto neighborhood across radio frequency, power-frequency electric and magnetic fields, and high-frequency voltage transients. A low-cost EMF reduction strategy implemented in a research house was reported to reduce exposure by an average of 80% for high-intensity EMF metrics.

Outcomes measured

  • Radio frequency EMF levels
  • Power frequency electric field levels
  • Power frequency magnetic field levels
  • High frequency voltage transients
  • Change in EMF exposure metrics after a low-cost reduction design/strategy

Limitations

  • Pilot neighborhood study with a small number of audited dwellings (29).
  • Specific measurement methods, frequencies, and quantitative baseline levels are not provided in the abstract.
  • Health outcomes are discussed generally but not measured in the described audits.
