Modern buildings require energy-efficient heating and cooling method for the both parts of the system, the heating/cooling source and the heating/cooling distribution system. Modern heating and cooling systems typically combine a reversible heat pump with a low temperature radiant system. Thermally activated building systems (TABS) use the large thermal mass of concrete from building structure as a buffer for lowering the cooling and heating loads during the day. In this paper we illustrate the floor covering infl...

Biochar is a porous, carbon-rich material produced by heating of organic matter to temperatures between 300 °C and 1000 °C in an environment with limited or no oxygen. During the past decade, numerous articles focusing on the use of biochar have been published, but have shown inconsistent results. Reactions in the soil after the addition of biochar depend on the characteristics of biochar, soil, climate and soil-inhabiting organisms. However, due to high variability in the quality of biochar, its effects on soils ...
