Drive-by thermal imaging highlighting site energy inefficiencies

New technology being developed by the Massachusetts Institute of
Technology (MIT) aims to use ‘drive-by’ thermal imaging to easily detect energy
inefficiencies in homes. Spearheaded by MIT spinout company Essess, the new
technology will be deployed on cars with thermal imaging cameras on
the roof to create heat maps of thousands of homes every single day.

Several cameras are deployed to distinguish the facade of each house
from the surroundings. The gathered images are then studied using complex
analytical computing power to assess where improvements in heat
retention can be made to save energy.

Any anomaly in the analysed data will be relayed to the utility companies
and the homeowner can be informed about having the issues fixed by
professionals. The system can even correlate its findings with demographic
information such as details of the age of the occupants or even the current
utility bills of each property, helping prioritise which households need the
most assistance in better managing their energy use.

Co-creator of the innovative system Sanjay Sarma explained that the
system aims to identify the worst offenders among energy-wasting households as
well as fix the issue. The new technology can also autonomously identify the neighbourhoods
that are most likely to be energy inefficient based on their location. For
example, the location of houses will often indicate the time period in which
they were built, with findings showing that older developments suffer from
poorer build quality than their more modern equivalents.

Thermal imaging can be a key tool in finding inefficiencies in building
thermography, ultimately having the potential to save both the contractor and
end user time and money.

testo 875-1i thermal imaging cameras are perfect for assessing
energy efficiency in both construction and industrial settings. Key features
include operating temperature range from -15°C to +40°C; and four-hour battery
life extending operation.
