A szerzők egy konnyűszerkezetes lakohazat vizsgaltak harom kulonboző hőszigeteltsegi fokozattal es harom kulonboző, fatuzelesen alapulo epuletgepeszeti rendszerrel kiepitve. A vizsgalatok eredmenye hetkoznapi ismeretekkel is feltetelezhető, hiszen mind a szigetelesek vastagsaganak, mind az epuletgepeszeti rendszer hatasfokanak novelesevel egyarant csokkenthető az epulet energiafelhasznalasa. Tenyleges ertekekkel azonban elsőkent mutathatjuk be, hogy mekkora fogyasztascsokkentest eredmenyez a komolyabb hőszigeteles, vagy egy modern napkollektoros, hővisszanyerővel kombinalt fűtesi rendszer a Magyarorszagon megvalosithato fa bordavazas epuletek eseteben. A cikkben bemutatott kilenc epulet mindegyike teljesiti a 176/2008. (VI. 30.) Korm. rendelet A+ energetikai besorolasat, de a leggyengebb es a legjobb kozotti tobb mint ketszeres energiafelhasznalasi mutatoval. Az epuletek a korszerű fa bordavazas epuletek energiafogyasztas-csokkentesenek lehetseges fokozataikent ertelmezhetők. = The authors examined a wood frame house with three different insulation thicknesses and three different HVAC (Heating, Ventillation and Air Conditioning) system – all based on wood burning. The results are evident without prior knowledge: the thicker the insulation, or the more effective the heating system, the lower the energy consumption. This is the first attempt to quantify this effect with scientific calculation for timber frame houses built in Hungary. The question was how large is the energy saving using thicker insulation or the application of a high end HVAC system with solar collector and heat exchanger. All 9 buildings presented in this article meet the standards of the A+ category of the governmental order 176/2008. (VI. 30.), but comparing the worst to the best, the energy consumption is more than double. These buildings show the steps of reducing the energy consumption of modern timber frame houses.
