to reduce simulation performance gap

A discrepancy between design simulations and performance of an actual completed building occurs on a regular basis. This is called a 'performance gap' and it is a major reason for building underperformance. The performance gap occurs in buildings made from well known materials, and even more so in buildings made from new materials, such as Hemcrete, which do not have an accurate and complete description in the mainstream simulation models. We have developed a method for reducing the performance gap using principles for digital signal processing based on Fourier series. The method is based on the creation of a digital filter that captures the relationship between Fourier transforms of monitored and simulated values of a relevant parameter in an existing building. The filter is then applied to simulation results of a non-existing building, morphing the results into values that are equivalent to monitored results of a non-existing building.
