Abstract: A fault detection system for detecting abnormal energy generation data from an energy generation arrangement. The system comprises an electronic processing arrangement able to identify abnormal energy generation data from an energy generation arrangement and alert a user where analysis of the energy generated indicates that it is operating outside normal operation with reference to upper and/or lower thresholds. The thresholds are determined by the system with reference to a peer group of energy generation arrangements.

Abstract: Apparatus for analysing the operation by a user of a temperature management system for heating and/or cooling a space within a building. The apparatus comprises a data processing arrangement configured to analyse a user control input to determine whether it corresponds to predetermined category of user input. If so, it calculates a value relating to the effect of the user control input on the energy consumption of the system over a subsequent time period and generates an output signal to cause a message to be delivered to the user comprising the calculated value.

Abstract: Apparatus for monitoring and analysing the performance of a heating and/or cooling system for a space within a building. The apparatus comprises a processing arrangement and an electronic memory, wherein the processing arrangement is configured to receive temperature signals representing temperature measurements from a temperature sensor within the space over a monitored period of time, to process the temperature signals so as to generate output data which attributes a proportion of the energy consumption of the heating and/or cooling system to a specified energy output, and to transmit the output data to the electronic memory for retrieval by a user. Corresponding monitoring and analysis methods are also described.
