We’ve touched on what a passive house is, the Passivhaus Standard and why we’re a-bloggin’. We’ve shared our research process with you as honestly as we could, much to the horror of some of our engineer friends out there – but we’re honest about how we approached figuring out where to start on our path. Consumer reality is often not as ‘organized’ as the industry experts might hope, and we feel it’s important to be true to our reality.
And it was at this point that we visited the Building Green Expo in November 2012. We’d spoken to a number of engineers before then, but it was at the Expo that our eyes were finally opened! We met with another 3 experts after the Expo, and after speaking with Stefanos Pallantzas from Project 15 and Nasia Roditi from Architect Lab we found the knowledge, expertise and chemistry we hadn’t even realized we were looking for.

A different and unique project starts, on one of the most favorite Greek islands - Paros! Follow step by step the construction of a Passive House (PassivHaus) through the first "Home Diary" in Greece! Project15, together with Green Evolution and ArchitectLab, are the project's major partners.

This build will be one of the first Passive Houses in Greece and the first on the island of Paros. Quite possibly on all of the Greek Islands. So we’re very much learning as we go along. And because the philosophy of Passive House just makes so much logical sense to us, we feel it’s our duty to share our learnings, our experiences and even honest frustrations as we go along with anyone interested to listen.

Ground-Air Heat Exchanger (GAHE) systems are nothing new. In fact the Romans first used a type of GAHE in what would become their great hypocausts heating the caldariums and tepidariums of their great bathhouses. These underground chambers, constructed as they were into the foundations of buildings, where essentially passages where heat or coolth was exchanged between hot furnaces or the cool ground as a way of conditioning rooms above to the desired temperature. While the hypocaust system is rarely built today, the GAHE concept is still common in Europe where a tradition of low energy buildings, lengthy perceived life-cycles for structures, and a broader interpretation of the human comfort range, make the systems very attractive.
The touted benefits include:
- Provides controlled fresh air ventilation that is filtered for dust and allergens
- Significantly reduces the amount of additional energy required to heat and cool a building, especially when combined with a heat or energy recovery ventilator (HRV or ERV)
- Lowers the relative humidity
- May eliminate the need for a central air conditioner in temperate climates
- Requires only a small amount of electrical power to operate an air intake fan
- May eliminate the need for defrost cycle in an HRV
