Metrology
As part of its energy auditing work, ENEOR uses its own measurement tools, guaranteeing complete control of the metrological instruments as well as the software for processing the data.
Electricity
The procedures inherent in electrical measurements require, according to audited systems, special authorisations, particularly high voltage/low voltage authorisation. The ENEOR team includes people who are authorised to make such measurements (e.g. low-voltage distribution panels, switchboards, etc.)
The equipment:
• Network analyser
• Protective equipment
• Multimeters
• Clamp ammeters
• Thermal-imaging camera
Thermal analysis
We have our own thermal-imaging camera, a tool which we use in a wide range of studies, including:
• Characterisation of a building's envelope
• Study of low-voltage distribution panels and switchboards
• Study of boilers
• Study of underfloor heating
• Study of hydraulic and ventilation networks
Combustion
The combustion sensor is used to a analyse heating installation in order to check the associated efficiency (net heating value, gross heating value) and to fine-tune polluting emissions.
CH4 + 2 O2 → CO2 + 2 H2O
Following analysis of the stoichiometric ratio of combustion, we recommend corrective actions in order to optimise energy efficiency and the amount of pollution from your heating installation: e.g. boiler, internal combustion engine.
Comfort
ENEOR deploys its own metrological instruments when conducting a comfort analysis, in accordance with standards ISO 7730 and ISO 7243.
By recording and analysing all of the parameters which affect the comfort of occupants, we are able to recommend corrective actions so that our customers are able to achieve an optimum level of comfort. The parameters studied are:
• Operating temperature
• Residual air speed
• CO2 level
• Lighting, brightness
Statistical parameters such as:
• PPD: % of dissatisfied people
• PMV: predicted average vote (the average value of votes from a large group of people on a 7-point heat perception scale)
• WBGT (Wet Bulb Globe Temperature): Calculation of the heat stress index.
• PHS (Predicted Heat Strain): described by standard ISO 7933, this method provides a more precise approach than the previous methodology
