Measuring heat loss with SmartHTC

Accurate thermal performance measurement

SmartHTC gives an indication of the true performance of the building that can be directly compared with the predicted performance. Our system is built on 10 years of academic research and has been tested and validated by 3rd parties and in hundreds of buildings.

Process for measuring thermal performance with SmartHTC

  1. Collect building information

    Basic building information such as location, floor area, attachment type, heating system and window type are gathered via a brief property survey or obtained from existing asset management systems or Energy Performance Certificates (EPCs).

    These can be entered directly into our online system or uploaded programmatically using APIs.

  2. Import temperature measurements

    A SmartHTC calculation requires 21 days' worth of internal temperature readings from a house. These can be obtained from existing smart thermostats or other compatible devices already installed in the property.

    Alternatively, discreet temperature sensors can be sent to the homeowner and placed around the house to capture the internal conditions.

  3. Import energy consumption data

    SmartHTC needs to know the exact energy consumption of the property to establish an energy balance. This means accounting for any gas and electric use as well as on-site generation from solar PV etc.

    Energy data can be obtained from existing smart meters with half-hourly readings or downloaded directly from compatible energy suppliers.

    Where a property doesn't have smart meters installed, it is possible to use manual meter readings as a fallback method.

  4. Upload data to API to get result

    Once all the necessary building information, temperature readings and energy consumption data has been collected, it can be uploaded to our API where a SmartHTC result will be calculated and returned.

    Data is sent to our RESTful web service in JSON format ensuring interoperability with all programming languages.
