Co-Heat
Co-heat testing calculates the as-built thermographic properties of a building (macro U-value). This is achieved by relating the thermal equilibrium state of the property, measured by means of a series of internal and external temperature probes, back to the power required to maintain its pre-set internal temperature.
This can prove invaluable for refurbishment projects, allowing quick evaluation of the effectiveness of proposed space heating load reduction works by comparing the energy required to heat the property before and after the works have been completed.
Throughout the test, the structure must be under complete control (i.e. it must remain empty, with no-one allowed to enter); otherwise the results will be compromised.
Each test will be logged for a minimum of 3 days (with an additional 2 days required for the property to reach the steady state temperature); however, the longer the logging duration, the more representative it will be.
