Saving energy with green roofs by measuring and calculating the thermal parameters of soil

Abstract

Installing green roofs on building tops is an important part of energetically conscious planning. This has many energetic advantages, while it is simply aesthetic. Opportunities of green roofs are in use in Western-Europe for a long time, and nowadays, more and more fine examples can be caught in our country, as well. This article is to summarize energetic aspects, which are worth to consider in planning green roofs. We confirm important role of green roofs in energetic calculations of building structures with citing different methods of measurement and calculation. Aim of these methods is to specify heat conductivity of soil, which is used for the calculation of heat permeability of the whole roof structure.
