Metroscale Analytics can capture up to 300,000 thermal images of 20,000 buildings in one evening from a single vehicle traveling on public roadways at speeds up to 50 MPH. This approach offers many benefits over handheld single house imaging and aerial-based imaging systems.
Hand-held cameras cannot provide a large enough comparison sample of buildings under the same weather conditions to make accurate assessment of whether a building is heated or not. This is because a thermal image is highly dependent on the material being imaged and weather conditions. For example, brick buildings often appear 10 degrees “warmer” than wood-sided buildings even if their interior temperatures are the same! Also, sun exposure and variations in cloud coverage create sudden large variations in temperature measurements. We grade building energy emissions relative to other buildings and account for material differences and perform comparisons under weather-normalized night-time conditions, thus eliminating common human error when evaluating just a few buildings. By imaging thousands of buildings over the course of a few hours, Metroscale’s algorithms have an abundant self-calibrating data source.
It is nearly impossible to offer similar levels of accuracy when using hand-held thermal cameras.
Metroscale’s mass-scale image acquisition technology decreases the cost of image acquisition to a fraction of hand-held camera inspections. This is the case even if performing inspections of individual buildings over larger geographic area because Metroscale’s imaging vehicles can drive continuously at speeds up to 50 MPH without slowing down at the target buildings. Using sophisticated optimized route planning techniques, we have imaged 2,000 specific addresses per night with a single vehicle; a rate that can not be matched by hand-held camera inspections.
The same cost-efficiency advantage also applies over aerial inspections as well. Our hourly operating costs are a faction of aerial surveys.
We see what smart meters cannot
Metroscale Analytics detects abnormalities that cannot be monitored through the metered infrastructure. Homes that are hot or cold when they shouldn’t be, overloaded transformers and specific energy efficiency issues (bad windows, missing insulation) cannot be accurately targeted by reviewing meter data even when sophisticated data analytics tools are employed. We help to detect bypassed shutoffs, bypassed meters, overloaded transformed that are essentially off the metered smart grid.
To maximize the results of your revenue protection program, Metroscale Analytics can easily integrate the output of smart meter data analytics programs or send our data to analytics programs to get the best of both metered analytics and not metered analytics in one program.
High-resolution street view imaging
Imaging from a vehicle, we see features and details typically missed by aerial applications. Also, varying roof materials, roof angles and long distances create incorrect temperature readings when using aerial imaging.
Metroscale typically images buildings that are 10 to 50 feet away from roadways using consistent angles to allow for reliable measurement of windows, siding, roofs and doors. This allows us to see features invisible to aerial imaging systems. Aerial systems attempt to measure rooftop temperatures from hundreds of meters away – and often measure them incorrectly. We can also see many more building details in our images because of our pixel size that can be less than one inch, whereas aerial systems can easily have pixel sizes in excess of one foot.
Metroscale promotes utility employee safety because they only have to visit those buildings that are highly likely to be of interest for revenue protection purposes. Our data has already been used to eliminate thousands of unnecessary visits in neighborhoods with safety-risk concerns.
Metroscale Data Processing
We deliver high reliability citywide data and not one-off incident reports. We integrate, verify and crosscheck multiple data sources to ensure that location, thermal, building details and utility data are all accurate for each building we evaluate. Our data is accurate and designed to drive low-level building-to-building decisions and to roll up for high-level citywide analysis.
Secure data available over the Internet
Metroscales’s system is designed for secure Internet-based access. All data and images can be viewed through a secure map interface or integrated into your own data processing tools.
No need to develop your own thermal imaging experts
As we discussed above, thermal images are complex to interpret and time intensive to evaluate against a sufficiently large sample set to obtain accurate results. Keep your investigators focused on revenue protection and safety issues and rely on Metroscale Analytics systems to be your thermal imaging experts.
Metroscale Scale’s thermal imaging system can be inexpensively drop-shipped to anywhere in the world where we can use local client or rental vehicles to deliver metroscale thermal imaging programs within days of receiving an order.
 Aerial thermal image temperature readings are highly sensitive to the roof material, angle of the roof, reflected sky temperature (affected by cloud coverage), changes in humidity, pollution and outside temperature and the angle of the images. While aerial imaging has been used successfully with flat roof analysis, the above factors substantially reduce the accuracy of aerial images for revenue protection or energy efficiency program purposes.
