Abstract:

This research focuses on the design features of daylight in buildings using CLT (cross-laminated timber) panels. As a rule, when factory-finished, the inner surface of the CLT panel has a natural wood colour. The colour palette of structural wood is rich in various textures and shades, which greatly complicates the process of determining the interior surface reflectance of these materials. A minimum of three colours can be present on one square meter of the CLT panel surface. This means that the reflection coefficient of the CLT panel surface will be determined as reduced to a single indicator. To improve the accuracy of calculations of daylight, the authors suggest clarifying the values of interior surface reflectance for wood materials and fixing them in regulatory documents. This requires additional research using a set of numerical and laboratory studies to refine the calculation methodology for this indicator. It is assumed that the developed recommendations for calculating the daylight of rooms in buildings using CLT panels will contribute to improving the energy efficiency of buildings, thanks to the rational selection of lighting devices and the calculation of the required illumination level. The implementation of the recommendations will create the prerequisites for the further development of wooden house construction in Russia and the world.
