A Methodology to Address the Gap Between Calculated and Actual Energy Performance in Deep Renovations of Offices and Hotels
A framework allowing measured (operational) performance to be compared with predicted (design) performance across all the countries in the ALDREN consortium using a harmonised approach and common language fed by a glossary of terms.
A “design for measurability” protocol that tracks the actions required during the deep renovation process, to ensure that performance predictions are as realistic as possible, that the construction and commissioning process is true to the design intent, and allowing the predicted performance to be verified through measurements.
A performance verification tool, which allows the predicted and actual (measured) performance to be compared at different levels of granularity.
The paper concludes that nearly zero energy performance targets can become measured outcomes, where driven by client leadership and wider team buy-in, and using the power of advanced simulation of HVAC systems to optimise design and ensure operation is aligned with the design intent.
