Electricity generation in the home: modelling of single-house domestic combined heat and power

Two models for predicting potential savings from a domestic combined heat a nd power unit are developed and compared. The first, a simple spreadsheet c alculation based on heating times and energy bills, gives a basic indicatio n of the benefits of domestic combined heat and power. The second predicts the electricity and heat demand profiles of homes based on building structu re, weather information and house energy bills, and simulates the operation of the unit to enable the savings for different ratings and efficiencies t o be predicted.
