The real estate sector is one of the economic sectors which, from the initial production phase to the consumption of the products and services it offers, makes a negative contribution to climate change. In particular, the housing market in Spain presents multiple opportunities to improve in terms of energy efficiency and shape a path towards a green and circular economy. The energy efficiency certificate is one of the instruments that allow improvements in this regard. The purpose of this chapter is to assess students’ preferences about the rental housing market and energy efficiency certificate. For this purpose, we propose the use of choice experiments as a tool to quantify these preferences. The study sample consists of a set of 254 students from the region of Extremadura, obtained from a simple random sample of students who rented a flat during their university studies. The main results show that the energy certificate is a relevant attribute in the choice of the apartment to rent; however, when the market segmentation is carried out, different groups are observed.
