Building dynamic simulation is a mature and advanced technique that has been used for decades to evaluate the thermal performance of building designs and existing buildings. Alternately, some researchers have developed reduced models that represent the thermodynamics of buildings using simple models based in real data. Lumped Parameter Models (LPMs), are lineal dynamic models that can be studied with the techniques developed in systems theory. This work identifies the LPMs that best represent 40 dwellings in the UK, and has applied system theory to study the response of those buildings in frequency to the driving forces of outside temperature, electricity and solar gains. The work has shown that the buildings present a response in frequency similar to low-pass filters with respect to outside temperature.
