MEASUREMENT OF OBJECTIVE AND SEASONALLY ADJUSTED PERFORMANCE

DIRECT COMPARISON BETWEEN PROJECT AND OPERATING SIGNATURES

BUILDING MANAGEMENT CHECK

 

 

 

The energy signature, on the basis of annex B of UNI EN 15603:2008, is a graphic that represents the average generation power according to external temperature.  

 

 

 

 

graficoLine slope is related to external temperature proportional effects such as building dispersion and proportional leakages of the system. If the building is insulated or the building efficiency increased, the energy signature slope decreases. The Ton abscissa indicates the external ignition temperature of the generator and depends from the internal set average temperature of the building and from free inputs.

Achieving an energy regeneration project, it’s possible to check the real seasonally adjusted energy performance. The positive result of comparison, between project signature, built by specialized thermotechnicians, and  operating signature, detected by Cheonix system, shows the correct design, installation and conduction of the building-plant system compared to expected results regardless of seasonality effects.

In addition, the comparison between successive years signatures, verifies the correct and efficient conduction. This allows to have immediate energy saving effects and costs optimization.

The following picture shows the comparison between two operating signatures: the first is derived from methane measurement and the second detected from energy produced. Slope difference represents the loss generated from the performance.
