Optimizing passive solar gain and using untreated local wood, this sustainable home on Lake Laka in Poland was designed by architect Piotr Kuczia. The south side soaks up the sun reducing the amount of active heating, while the north side opens up to vistas of the lake. Many of the materials were locally sourced, reducing the amount of unnecessary transport required for construction, hence the moniker CO2 saver. But there are many other ways that this home saves on CO2. from CO2 SAVER
