now my wife wanna add another toilet next to the laudry area.
5 toilets for 4 people? what for need so many toilets ah?
initially she wants the toilet inside my garage. saying the garage is too big for me.

doubt other people is gonna be as detailed as this.
it's my own house, might as well make it as properly engineered as possible.

light simulation for the house.
geo-referenced to the accurate GPS position, and aligned to the accurate alignment using a compass, compensated to true north of course.



this is how it's gonna shade at 4.30pm, in december.

other than a single point in time, i've also simulated and animated the sun position throughout the entire year, and sun movement from early morning to late evening,
all to avoid getting too much evening sun to the bedrooms.

also got a cost quote for individual AAC bricks.
one wall is gonna be ~RM200 extra to adopt AAC. rough calculation it's gonna be RM1k-ish (under RM2k) to adopt AAC for the entire bedroom wall. there's also an option to use cement brick for the toilet wall and just AAC the 3 bedroom wall and master bedroom. that should bring down the extra cost closer to RM1k.

seems that AAC doesn't cost all that much compared to cement bricks. might even be the same cost as clay bricks.
