Eco­no­mi­cal eva­lua­ti­on bet­ween PH and ne­ar­ly Ze­ro En­er­gy buil­dings in Gree­ce

The eva­lua­ti­on sho­wed that even in con­struc­ti­on costs the MF Pas­si­ve Hou­se is 18% chea­per than the NZEB one. The SF Pas­si­ve Hou­se is al­so 8% chea­per than the NZEB one. At the sa­me ti­me PH per­forms 4 ti­mes bet­ter than the best hou­se that can be de­li­ver­ed by na­tio­nal law and this wi­thout any per­for­man­ce gap. This ma­kes PH the sa­fest so­lu­ti­on to ach­ie­ve nZEB in Gree­ce.

A land­mark for the com­mu­ni­ty on the Ad­ria­tic coast: the Pas­siv­haus ME­GA­BOX of­fi­ce

Mega­box is an of­fice build­ing on the Ad­ri­at­ic coast, built with the aim at be­ing pleas­ant and com­fort­able for the em­ploy­ees and a land­mark for the com­mu­nity. The many chal­lenges (ori­ent­a­tion, thermal bridges, shad­ing) have been over­come while us­ing PHPP as a de­cision-mak­ing tool. It turned out that PH was the most eco­nom­ic­ally con­veni­ent vari­ant with no ex­tra costs.

Cost op­tim­al nZEB res­id­en­tial new builds

To de­term­ine the nZEB stand­ard, li­fe­cycle costs are cal­cu­lated for dif­fer­ent shell qual­it­ies and com­bin­a­tions of build­ing ser­vices us­ing three ref­er­en­ce build­ings. This makes it pos­sible to es­tab­lish re­quire­ments for an nZEB, which are then com­pared with the Aus­tri­an nZEB defin­i­tion.

Mind the gap: nZEB and Pas­siv­haus: An Ir­ish per­spec­ti­ve

Ire­land was an early ad­op­ter of Pass­ive House with the first in 2005. Since this date the take-up of Pass­ive Houses has fluc­tu­ated over the years due to the re­ces­sion and this pa­per in­vest­ig­ates wheth­er the take-up of Pass­ive Houses un­der­tak­ing full Passivhaus cer­ti­fic­a­tion is re­du­cing due to the re­quire­ment of new houses to be Nearly Zero En­ergy Build­ings (nZEB).
