Challenges in Combining Different Methods and Tools for Improving Performance Monitoringin Buildings

Reduction of energy consumption in buildings is a vital element in the long-term transition towards low-carbon society The EU has identified buildings as being the most promising target for improving energy efficiency and has quantified a significant energy-saving potential associated with infrastructure and equipment investments Challenge - How the region/city/state can promote greater adoption of new and efficient technologies by consumers? Plan-Do-Check-Act (Adjust) – Sounds simple but… Copy-paste planning - the most frequent mistake! Key performance indicators – the purpose of benchmarking, measured energy consumption and proposed recommendations Policy point of view - there is a challenge to link real energy consumption data with governmental financial support programs, training for building managers and tailor-made information campaigns for building users Operational point of view - it is crucial to properly present real consumption data to ordinary people which in many cases do not understand differences between calculated and measured energy consumption There is a need to combine different methods and tools! Integration of energy within the activity flow charts, basis for decisions on setting up the structure of ECC On the conceptual level, this method belongs to the family of process integration methods It provides methodological approach for connecting energy and activity diagrams into overall framework for improving energy performance DEA is a non-parametric method based on postulates of mathematical programming and it is used to measure the performance or effectiveness of private sector companies or public sector entities It is used to compare decision-making units (alternatives) in terms of their efficiency in converting inputs into outputs It is not possible to explicitly relate and mathematically formulate relationship between selected input elements that are participating in the creation of the desired output values - weighting factors for inputs and outputs are not determined by the end user, but they are calculated by a linear optimization procedure for each individual business entity DEA can be implemented on a set of comparable business entities belonging to the same sector Introduction of dynamic and context-sensitive indicator called Energy Performance Coefficient, which is the ratio of actual (measured) to predicted, estimated or benchmark energy consumption, can be part of the solution Models must incorporate the required knowledge on how to correctly interpret different values of key performance indicators.
