Environmental Design
A penny saved is a penny earned, they said. So with joules of energy!
The Site
Buildings, as they are designed and used today, contribute to serious environmental problems because of excessive consumption of energy and other natural resources. The close connection between energy use in buildings and environmental damage arises because energy intensive solutions sought to construct a building and meet its demands for heating, cooling, ventilation, and lighting cause severe depletion of invaluable environmental resources.However, buildings can be designed to meet the occupant’s need for thermal and visual comfort at reduced levels of energy and resources consumption.
“Las Vegas” The anthill in a dessert.
1 The extension building is designed such that there are some additional seating for the restaurant, some of which will be in the open area. The building could adopt a mixed system of ventilation, this would save on energy.
The Climate Analysis Climate: Sub tropical arid climate, because it lies within the Mojave Dessert. The analysis tool indicates that it is hot and dry for most of the year. The city enjoys the sun throughout the year, with very high temperatures in summer.
The Orientation N
BAD: Orientation in any other direction gives more radiation during summer and less during winter.
S H E E T
Tutor: Spyros Stravoravdis Student: Nidhi Shah
BEST: Correct orientation gives more radiation during winter and less during summer.
182.5 Degree is the best orientation

The best strategy to keep the building cool will be Indirect Evaporative Cooling.
The structure is orientated to take maximum advantage of the sun at the same time not to allow the building to overheat in summer.
The Wind Analysis N N
Ÿ Micro-climate has been created by placing water in the West
The direction of the wind is from the West for all year long. It does not change considerably.
The west wall is staggered to take maximum advantage of the wind.
such that the wind can carry some amount of cool water vapor and increase the humidity of the air. Ÿ The new building is placed very close to the old so that shadows cast all the time on the southern facade. Ÿ The form has been derived due to the direction of the wind and d best orientation for radiation.
