The following conditions are necessary for mold growth to occur on surfaces:
Since the first three conditions are present in most building environments, moisture is often the primary condition we attempt to combat in the fight against mold growth. Unfortunately, moisture makes for a cunning enemy because of its
ability to infiltrate openings in a building’s shell both as a liquid (e.g. bathrooms, kitchens, pipe leaks) and as a gas (e.g. travelling water vapour, exhalation by occupants, attachment to clothing). When all four conditions are
present, mold growth typically occurs either at the source of the leak or where moisture in the air first makes contact with the coldest surface in a building (e.g. a window, framing, exposed exterior materials). The latter is how
mold often ends up in unexpected places. When moisture in the air hits the colder surface, it transforms into a liquid on the building material through condensation (think cold drink on a hot day), creating an ideal environment for
To most accurately predict mold germination and growth, we need to measure the composition of all four conditions at each surface that is a potential risk (e.g. window one, window two, building crack one, etc.). While very expensive, this
approach also assumes a building operator can successfully predict exactly where mold will eventually first occur. Tricky business.
Rather than measuring for all conditions at each individual surface, Solve™ provides a heuristic prediction approach by continually monitoring a robust area (e.g. basement) and calculates its moving ‘Dew Point’ temperature to determine
critical mold growth environments. Dew Point temperature is scientifically seen as the most practical indicator to predict mold within a high probability. Solve calculates Dew Point in real-time using inexpensive sensors that monitor
an area’s ambient temperature and relative humidity, drastically reducing the building’s costs.
As Solve continually calculates Dew Point, it weighs it against the real-time relative humidity data to report on which building areas exhibit mold growth environments. Because building surfaces commonly cycle between wet and dry states,
Solve also indicates how often mold growth conditions occur and when they’re occurring. This makes it easy for building operators to understand the relative conditions of each area, which are the highest risks, and which are the most
Building operators can then proactively take informed action to offset mold growth conditions by reducing the moisture content of the air, increasing air movement at the surface, or increasing the air temperature.
Place a small battery-powered wireless sensor in each room to be monitored. Connect a LoraWan gateway to your local network (similar to a wifi router).
The sensors send raw environmental data through the LoraWan network to Solve™, where it's decoded, assessed for alerting conditions, and saved for reporting.
|Hardware sensor||$40-$80 each|
Your existing (non-technical) staff typically does the onsite installation of the gateway and sensors. Solve includes free onboarding and support.
|Each registered user||$39|
|Each monitored point||$4|
Solve™ is a monthly subscription, and the total price is based on the number of active users and monitored points. Solve Core includes the use of the Solve CRM/ticketing apps, IoT cloud hosting and management, security, awesome support, third-party integrations and free updates. The LoraWa network is provided by a Solve supported LoraWan network operator like MachineQ, TheThingsNetwork, etc.
Once the LoraWan network and Solve accounts are in-place additional solutions can be layered in by simply installing more "sensors" and enabling the corresponding "monitored points".
