RETROFIT OF BUILDING INSULATION De ne the questions relating to the project risks Identify if relevant modelling tools available Determine if relevant modelling inputs available De ne modelling approaches appropriate for the project Collate inputs; material properties, internal conditions, and weather data Consider measuring conditions and/or material properties for additional certainty Run model(s) to generate outputs for evaluation Which measurements are required? Design in-service monitoring installation Run in-service monitoring, ideally for at least 3 years If data shows failure(s), trigger mitigation strategy Consider disseminating experience and ndings to a wider audience Use experience and information collected to inform future projects Analyse data periodically and report back to the project team Design monitoring Acquire internal conditions and/or weather data where missing Monitor base case (and test speci cation) for, ideally, one year minimum From monitoring ndings, develop, re ne or con rm speci cations and/ or site practices IDENTIFY THE RISKS Can the risks be managed? Retro t insulation is inappropriate Install insulation and monitoring Install insulation to modelled speci cation Install insulation to speci cation Do ndings raise concerns, require further monitoring and/ or action? Does the test speci cation performance need to be checked? Does the modelling indicate concerns for the speci cation? Would monitoring help con rm/re ne modelling results? Could monitoring help answer the questions? Use monitored performance data to calibrate models Modelling is reassuring but questions remain Continue monitoring to check success of mitigation Adjust speci cation Is modelling a work ow viable for the project questions? Will modelling provide enough certainty? Are the risks understood? YES NO YES YES NO YES YES NO NO NO NO YES YES NO YES YES MAYBE NO NO Are measurements & monitoring of base case & any test speci cations possible?
