climate annex B
Hot and humid climate annex
For coastal, monsoon and tropical sites: heat, heavy rain, damp air, salt near the sea and strong storms.
what changes
Six changes for this climate
| Part | What changes |
|---|---|
| Shell | Raise the base above the known flood level. Wide roof overhangs keep rain off walls and doors. Use coatings that resist rust and salt. |
| Glass | Shade all glass and keep openings sheltered from driving rain. Insect screens on every opening window. |
| Cooling and air | Cooling must also dry the air. Give wet rooms and stores steady extract so mould cannot start. |
| Water | Large gutters and downpipes, checked before each rainy season. Harvest rain where the local rules allow. Drains sized for a cloudburst. |
| Energy | Solar roof with fixings rated for storm wind. Keep the battery and boards above flood level. |
| Ground and outside | Covered walkways between modules. Ground slopes away from the base on all sides. Anchors designed for storm wind by the engineer. |
Planning values for teaching and early design. A licensed local engineer and the local authority confirm every real project.
what never changes
The core stays the same
- The module, the element codes and the naming rule.
- The space programme and the seat rules.
- Two exit routes from every floor, guard rails at 1.1 m, and step-free access.
- No supplier or maker names in the model, the drawings or the lists.
- Where a local rule is stricter than ours, the local rule wins.
three checks
Check the model for this climate
- Is the floor level in the model above the recorded flood level?
- Does every wet room and store have extract?
- Are anchors and roof fixings marked with their wind rating?
your task
Try it
Take the full satellite and add covered walkways and gutters. List the new elements with codes and units.
