This presentation will explain what exactly calibration should mean. It will also look into the hierarchy of and the differences between the calibration labs of national standards, accredited labs (like DAkkS, a national government-appointed accreditation body in Germany, or Cofrac – Comité français d’accréditation – in France), and manufacturer’s calibration labs. Even the labs themselves must have their own measuring devices checked in order to guarantee what is known as traceability to national standards, and to determine the measurement uncertainty of their testing devices.

This paper presents the development of a computer model of an academic building using the EnergyPlus program and its calibration with monitored data. The new Concordia Sciences Building (CSB), located in Montreal, has a total floor area of 32,000 m2. The size and the complexity of the heating, ventilation and air conditioning (HVAC) and heat recovery systems make the modeling process a challenge and an excellent opportunity to evaluate the capabilities and features of EnergyPlus in this particular context.

Reliable prediction of daylight availability in indoor environments via computational simulation requires reasonably detailed and accurate sky luminance models. In this paper, we compare three calibration methods to derive detailed sky luminance maps from digital sky images. The results imply that digital sky imaging calibrated with parallel measurements of overall horizontal illuminance levels, can provide an efficient basis for the generation of detailed sky luminance models.

French standard for airtightness measurements is NF EN 13829. It is completed by French application guide GA P50-784, to set calibration rules more precisely, among other issues. This guide was published in 2010. To answer measurers’ remaining questions, a Frequently Asked Questions web site was created by CETE de Lyon.
