Abstract | Energy monitoring is needed in domestic retrofit project to evaluate the performance of energy efficiency technologies in retrofitting projects. Energy consumption must be monitored before and after the technology installation. While energy monitoring technology is widely available and can cover for a range of budgets, energy efficiency retrofit projects are being faced with a hard choice of imposing a high expenditure in monitoring equipment but able to reliably capture a big range of data at short interval or facing a low budget monitoring approach resulting in a reduced amount of data captured, periods of missing data and issues in measuring the benefits of retrofitting efforts. The aim of this study is to propose a monitoring methodology for domestic properties and compare to other monitoring approaches to measure energy consumption and target energy reduction due to energy efficiency implementations (technology approach) and/or user behavior changes (human approach). The methodology was developed on the basis of the experiences and feedback captured during two retrofitting projects accounting for the energy reduction of domestic properties after the implementation of air source heat pumps (technology approach) and user behavior strategy. Three parameters are used to compare and evaluate the proposed monitoring methodology to other monitoring strategies. Local authorities, social landlords and general energy users can implement this methodology in a low budget approach to be able to measure the results of implement energy efficiency changes to a range of properties and make decisions on the success or changes to be made to their retrofitting strategy. |
