Indoor Environmental Testing
Projects plus offer bespoke scientific testing services for anything related to contamination in the indoor environment such as damp, odours, chemicals, fire or mould.
Whether establishing the extent of contamination after a fire, the cause of an ongoing damp issue, the efficacy of decontamination after a sewage incident or the air quality post verification following construction works.
Air sampling
FAI - Fungi to Allergen Index
The Fungal to Allergen Index (FAI) is a system of measuring the amount of mould compared to the total allergens.
This relative measure of mould against the total allergen biomass is expressed as a number, which if high would indicate that there is a high level of mould, indicative of mould growth and an associated moisture problem.
Mycometer FAI sampling is also able to indicate the efficacy of the cleaning programme in the property based on the FAI score, this can save money on costly mould remediation if the problem is due to ineffective cleaning and not excessive mould.
Mycometer® air Fungi is the state-of-the-art test method for onsite quantification of fungal particles in the air in less than an hour.
The methodology measures the level of fungal particles in terms of viable and most nonviable spores and hyphal fragments. Two independent peer-reviewed publications have shown that it also measures microparticles from the fungi. The Mycometer® air Fungi methodology quantifies fungal particles in the air by measuring the level of the enzyme, β-N-acetylhexosaminidase (NAHA), from airborne fungal particles captured on a 0,8 µm pore size filter.
The Mycometer protocol is unique in that it employs ACTIVATED AIR SAMPLING this is a process where the air in the area to be tested is agitated/disturbed in a controlled manner. This allows testing for those particulates that due to their weight are not suspended in the air for long periods but can become airborne through disturbances in the air patterns, such as when a door is opened or closed or when a person moves through a room.
The passive air sampling that other testing systems employ does not account for the contaminants mentioned above and will therefore give inaccurate data on the contaminants that are affecting the indoor air quality
Surface sampling
Surface Sampling and Testing is a robust methodology that has been meticulously developed over a decade in partnership with mould remediation consultants, contractors, and the Danish Building Research Institute. This method has consistently demonstrated its effectiveness and value.
The results are categorised empirically into three distinct classifications: clean, dirty, and contaminated. A ‘clean’ status signifies a background level typically found on visually clean surfaces in well-maintained buildings devoid of mould and moisture issues. ‘Contaminated’, on the other hand, refers to samples that contain mould concentrations exceeding those found on dusty and dirty surfaces in similar well-maintained buildings.
The interpretation criteria align with the guidelines set forth by leading international bodies, including the World Health Organization (WHO), the New York City Department of Health, and the US Environmental Protection Agency (US-EPA).
It is important to note that all mould growth, regardless of species, can potentially impact health and should be promptly removed. To facilitate this, protocols have been established to measure mould contamination within porous materials. These materials, which include insulation materials, cement-based materials (such as concrete, plaster, and mortar), and other porous materials commonly found in buildings, can harbour mould growth deep within.
The Mycometer technology, a cornerstone of this methodology, has undergone rigorous daily testing for over 15 years by consultants and contractors across tens of thousands of mould remediation projects.
Several independent scientific papers have documented the principles underpinning the Mycometer technology. Furthermore, the technology received verification from the US Environmental Protection Agency (US-EPA) in 2011, further cementing its credibility and effectiveness
Legionella
Fast and accurate legionella testing. Legionella is a form of bacteria, typically found in low quantities in groundwater and other naturally occurring bodies of water. However, when Legionella bacteria find the optimal environmental conditions within man-made structures, they can readily proliferate. Legionella bacteria can be harmful, especially to vulnerable or immunocompromised individuals causing pneumonia like symptoms. This is why precautions should be taken following water events.
Projects Plus contextualise the results of testing, letting you know the required actions to decontaminate.
