A new IEA-EBC Annex has been formed.  Annex 94 ‘Validation and verification of in-situ building energy performance measurement techniques’, will commence its preparation phase this autumn.  The annex was proposed by Prof Cliff Elwell (UCL) Prof David Allinson (Loughborough) and Prof Richard Fitton (Salford).  There will be a kick off meeting in autumn 2024, location and date TBC.  The annex has the following aims:

• Provide datasets and findings to accelerate the development of measurement methods.
• Establish a methodology for validating these methods and achieving consensus on approaches for calculating uncertainty.
• Generate a database of real measured buildings and calibrated energy models.
• Develop new and improved methods of HTC (Heat Transfer Coefficient) measurement virtually.
• Focus on potential applications of these methods and requirements to meet user demand.
• Investigate translating HTC results into actionable insights.
• Study investigative techniques to disaggregate the HTC for detailed performance gap analysis.
• Collect a large global dataset of typical dwellings under different climates.
• Enable the development of measurement techniques for cooling-dominated climates, addressing the current research focus on heating-dominated climates.
