Detailing for heat & moisture Ching 07: moisture and thermal protection.
How to make sure that water doesn’t penetrate (渗入)building and that heat float is controlled according to climate.
Roof Water hitting roofs need to be carried away from the building. Strategies are eaves gutters into down pipes into the water drainage. If the roof drains internally, they might be a parallel wall outside, box gutters be used and typically those box gutters carry water to the outside of the building they don’t draining down through the building because that becomes a high risks situation. If that drainage pipe ever get blocked, likewise flat roof mostly be drained outside a building.
Eave(屋檐) helps building because there’s less likely to creek back towards the wall and it protects some of the wall surface. Walls have various strategies, they might be an attempt to put absolutely previous surface on the outside that’s probably the least successful strategy. Another strategy is to have a double skin wall like a brick compact wall. The final strategy is a rain screen system which attempts to equalize forces to prevent water entering. They quite complex concepts to understand. Where materials join each other need to consider like: windows, joints of wall that’s a high risks area for water penetrating. Likewise when a surface is broken in this case is a chimney that’s penetrating the roof flashing(防水 板) is required around that chimney.
Dry land: Agricultural draining, this is a small plastic pipe. This section of ground is cut away and filled with a kind of loose add with it, so water drains clearly down to the agricultural drain. If any water gets carry away from the building and into a store water pipe.
Wet land: Water proof membrane, particularly made out of artificial rubber around the construction
