    Abstract : Popular Abstract in Swedish I Norra Skandinavien, liksom i andra kalla områden, är oftast de urbana dräneringssystemen inte kapabla att föra bort de stora volymer smältvatten som ofta belastar systemet under flera veckor under snösmältningen. Högt vattenflöde till reningsverk, översvämning av kombinerade system och låg vattenkvalitet är några problem förknippade med snösmältning. READ MORE

  3. 3. Reduction of prime energy consumption by ground source heat pumps in a warmer world
