Strategies to reduce heat load Light Sources

The plan shows the reach of the light on floor, which is 15 feet away from the windows.

Cross Ventilation

A wooden entry in the south façade with big and small patterns is inspired by "the mashrabiya," which is an old Arabic technique to cool interior spaces and to minimize the amount of light entering the building. The small pattern in the top of the walls will be used to ventilate the space, and it has sensors to close the glass windows behind the wooden patterns automatically.

One of the most common means of cooling is comfort ventilation to help cool the interior of a space. For a West Texas climate, cooling could be accomplished by having small window openings in the top of the walls and another opening below in the interior walls that can move the hot breeze out from the interior places; it can also cool the thermal mass. Moreover, some opening in the suite doors that faces the corridors in the simulation center and having ventilation slots in the bathroom could also help complete the cooling cycle, and will help ventilate the place better.

Using windows that can move up and down can provide shading and ventilation systems. Additionally, the use of glazing, which has a very low U-value of 0.78 W/m2K, for the windows can reduce transmission losses and create the “greenhouse” effect. Also, it could be better to use sensors to close the windows automatically when the temperature is high in the interior spaces. During summers, the cooling can become an issue that is hard to solve using passive cooling, but using this technique can help use less energy to cool the space.

Inspired by The Mashrabiya

Shading West Façade It is difficult to shade the west side of the building. Therefore, the goal for west window is just to shade as much as possible. After identifying the full shade angle for the west side, it was found that using vertical fins is one of the best options. Furthermore, for the west entry, the same wooden pattern used in the south façade will be used.

South Section, Double Height

Double Skin Façades Glass façades that face east and west can provide natural ventilation and passive cooling. The system was created for use in a different way during summer and winter, according to the weather. The glass in the summer can reflect solar radiation with a system of lamellas to shade the sun. Meanwhile, in the winter, the system is closed, and thereby keeps hot air inside the simulation center. Applying the double skin façades can help improve the daylight conditions and reduce the use of electricity. Double skin façades can solve several issues of passive heating and cooling. Furthermore, the design of the existing façades needs be changed in order to implement the double skin glassing correctly.

Wind Towers

One good solution to be used in this project is wind towers that could be designed in the East and West area, according to the wind directions. This technique was created many centuries ago to provide ventilation. These towers can help direct the breeze to come into the interior through the chimney and refresh the air by allowing the air to move through the corridors. Also, the window panels along the west side of the building used for shading can help in ventilation too.

Courtyards

Sustainable Design Strategies One of the solutions implemented in the project is two large indoor courtyards. This would provide day-lighting to the interior. The is courtyard located in the middle of the building, the debrief rooms facing the courtyard on the first story, and the offices face the court yard on the second story.

Skylight

Rain Water Harvesting The rainwater harvesting system is comprised of a catchment area, storage tanks, filler, supply facilities, pipes and overflow units. The stored water should be used for non-potable functions such as toilet flushing, washing hands, pavement cleaning, and irrigation.

Green Roof

Active Solar
 Having a skylight in the top of the offices area in the second story can provide more day light to the offices. Colored glass is used to control the amount of light coming from the ceiling.

The PV panels can be used on the roof in order to change sunlight directly to electricity.

The PV panel angles are very important to get the best result.

So for this location to get the greatest benefit, the PV should face south. A movable system to follow the sun direction should also be created for the best benefits in this type of climate.
