Cooling a roof with solar panels or a double roof

We are past the Songkran holidays here in Bangkok now and the weather is really getting quite hot. The good news is that the low thermal mass design principals we’ve gone for have been very successful in releasing the heat of the day quickly at night allowing the house to be cool enough to sleep…


Measuring the wind pressure force on the floating house

We are getting very close to the point on BaanLoiNaam that we will be adding the propulsion systems. To review, the house is designed to be able to operate completely independently from land and to move around the pond under it’s own power and rotate to track the sun, etc. So before I can spec…


Kitchen building walls are done

The kitchen building has been mostly on hold while we finish up a number of things on the floating house (BaanLoiNaam). But we did manage to finish all of the walls on it. Next we need to schedule the workers to install the doors and windows. After the Songkran holidays, though.


BaanLoiNaam balcony has cool “secret” storage areas

The odd balcony storage areas in BaanLoiNaam have been completed. On the near side is where the bed can slide out from inside the house when not in use. But we added a hinged door with a lift support strut to keep it open when we need to clean out this area. (Our bed is…


BaanLoiNaam bathroom update: fresh water testing

So we installed a water tank under the roof of BaanLoiNaam a while back, and recently got the sink and shower heads connected up so we decided to test if the water pressure is enough. The sink worked fine… But the shower head was a little on the low pressure side It is probably usable…


Sink in BaanLoiNaam installed

Here is a picture of the sink installed in BaanLoiNaam… You can see the cattails planted in the box beneath it. These will hopefully grow up to make a “green wall”.


Spirulina culture failed

I posted a while back that I was trying to see if I could culture my own fresh spirulina, but after letting the whole setup sit for about a week, it is clear that it failed. This isn’t a bad thing. It was only an experiment, and as I wrote when I started, there was…


Composting toilet update: building some additional holding tanks

We’ve been using the composting toilet in BaanRimNaam since we moved in late in December last year, and I like it a lot. Call me weird (many of my friends have), but I really like understanding and implementing the full path of our food from growing to cooking to eating to … well processing it…


Using a siphon to control the water level in the planter box

In exploring the idea of using the cattails in the bathroom of BaanLoiNaam as a kind of constructed wetland water filter for the grey water coming out of the sink and shower, I was consulting with Bob Crosby of Biorealis and he mentioned something interesting about siphons. The idea is that in a wetland like…


Pond update: measuring the water level drop

We are coming to the end of the dry season now. Last week we have had the first real rains of the year, so I figured it was a good time to evaluate how low has the water level in the pond dropped. This may provide an idea of what to expect in future years….
