|Suspended radiant panels heating – Part 1|
The authors present a simplified method of radiant panels heating design. The simplifications in comparison with ČSN 060215 and also with more complicated theoretical calculations are founded by long-term development, experience and experimental knowledge. The proposed procedure enables to include boundary conditions, smaller height of panels suspension, influence of environment dustiness and also different slope of radiant panels in a simple way.

|Special characteristics of long delivery lines designing in application of PEHD piping thermoplastics|
The article continues the similar problems published in VVI 4/2001, p. 168 “Summarisation of small local loss in designing plastic piping”. The contribution informs about one dearly paid experience and explains the causes of the design failure by means of a model example which can serve as a manual for trying to avoid similar situations.

|Wood waste utilisation from the point of view of contaminants emissions|
The author treated the article with regard to government order No. 195/2001 Coll. according to which the usability of renewable energy sources is evaluated. It concerns the potential of reachable energy savings and also the local decreasing of the environmental load of outside environment. The article is oriented to evaluation of contaminants emissions and energy contributions when burning wood mass.
