| Calculations show that overheating in glazed balcony and apartment will not rise significantly in the facade as proposed, due to the east orientation, the large openable windows and the potential for internal sun shading. |
| Both mechanical and natural ventilation can be combined with openable windows. |
| A small openable window at the outer end of each duct allows air to enter the ventilation stack. |
| The north wall opens up to the sunken courtyard to draw in cool air, and the tapered lanterns serve as thermal chimneys, with openable louvres to evacuate hot air. |
| A water heater flue pipe should extend at least 12 inches above the roof line and should terminate no closer than four feet from an openable window. |
| That is why all the front panels are openable and can even be removed thanks to simple hinges. |
