This research will examine a design for an off-grid safari park in Iran. During this research different passive techniques from the vernacular architecture will be discussed. These principles will be used to reduce the energy demand of the safari park, since it should be an off-grid park, in order to deliver a design proposal with an achievable energy balance. One of the buildings, the entrance building, will be used as a case study to test the design principles. The courtyard, the increase of mass and the windcatcher are the most important principles to be implemented in the building. The energy reduction achievable with these techniques is weighted against the increase in cost of the building. In the design of the entrance building, a combination of windcatchers and underground ducts is used to cool the building, reducing the energy demand for cooling with 90%. Other principles, like an increase in mass and a courtyard also reduce the energy demand of the building significantly. The use of vernacular principles in the design will increase the cost of the building. However, it will decrease the cost needed for generating energy on site and, therefore, it is still beneficial. Future research, should focus on the exact amount of energy needed compared to the additional cost for the construction of the buildings. However, this research concludes that the use of vernacular principles in the park is beneficial.
