Is this sarcasm ? because sounds like sarcasm. If Grok generating naked images of children is your ideea of free speech no wonder nobody takes a stand against Trump and Co., you so…

If you think house prices are a joke now, just wait 2-3 years. I'm actually a structural engineer with a passion for passive houses and went into programming 8 years ago. I designe…

House prices per sqm in Romania based on average net earnings per month is lower than ever, lower than 2014 when price per sqm were at the lowest after the 2008 financial crisis. W…

Avocado does not grow “true-to-seed”. It will not work.

Just yesterday my father's Philips CPAP was replaced after more than a year of complaints to Philips Romania. Thanks to HN I read an article that said Philips put a lot of money as…

You need a separate hot water tank and a 3-way valve, when hot water is requested the hot water from heat-pump will get diverted into the hot water tank (puffer).

You're welcome! I live in Europe (Romania) and to be honest I would not know what to expect in terms of costs. You lose at least 25% of your energy trough the roof, this can even g…

1. I would start by lowering the ceiling and insulating it. For ceiling if you insulate it using mineral wool, or glass wool... the vapor barrier [0] is critical and must be placed…

I want to also to highlight the importance of the building airtightness (Air Changes per Hour) on the energy consumption needed for heating. I saw an example at some point in one o…

Exactly what coryrc said in his comment, for a PassivHaus you recover very slowly the cost of the heatpump and if it brakes once in 10-15 years while it takes to recover the invest…

I agree, you do not need concrete and brick but you also need to take into account the local traditions. For ex. building a wood house (framing or CLT) would have cost much more th…

Small in comparison with a typical single family homes that goes >150 sqm in my area. I completely agree with you, 99 sqm is more than enough for a 4 people family.

Really interesting. I've read about also "foundation insulation skirt" that allows you to create a warmer earth mass under the house. To be honest this was the biggest "complaint" …

Instead of a heat recovery ventilation you can use energy recovery ventilation which gets back some of the humidity, otherwise just buy a cheap electric boiling humidifier and it y…

First of all, if you build a PassivHaus in normal climate (not cold) you will be amazed to see that you do not need a heat pump, you can just use normal electric boiler for hot wat…

You must also be careful on how you mount the windows. Have a look at the german standard called "RAL montage" to see that you need an inner and outer membrane and then have a look…

I've also built a simple and small (99sqm) PassivHaus in Romania, 5 years ago. Everybody, and I mean everybody from family to friends called me nuts, but I've got my payback this w…

Foam insulation has other problems, see for eg. thermal drift.

Seems up-to-date. I was not aware that the list is so long...

Indeed. Autodesk Advance Steel generated fabrication drawings need a lot of effort to get it right but AS was ahead of Tekla in regard with connection design and modeling/detailing…

As an structural engineer and former Autodesk user, I completely agree with the letter. I always saw Autodesk as a company where software goes to die a slowly painful death. It sta…
