    A fire simulation was conducted in an enclosed enclosure with CFAST, considering the combustion of office real estate, materials and equipment in the LACONAL of the University Technical of Ambato. The design was developed in two phases. The first with the determination of water extinguishing conditions for an area of 264.04 m2 is obtained 24 sprinklers for an optimal design, considering a total flow rate for the system of 4119.02 L for min and a volume of water for the supply source of 596645.17 L according to NFPA 13 and UNE 12845. The second phase simulated a fire under environmental conditions of average temperature of 20 Celsius degrees, humidity of 53 percent, atmospheric pressure of 101500 Pa and oxygen limits of 5 percent. The simulation time, thermal properties of materials for floor, ceilings and walls, the geometric dimensions and coordinates of each compartment, the location of door and window openings in each of the compartments, HRR curves, the coordinates of each of the objects produced as the fire source, and the location of each sprinkler were determined. The maximum temperature profiles of the hot gases were 114 Celsius degrees at 75 seconds of the simulation. The time when the lab reached 20 Celsius degrees was 2110 seconds and the smoke evacuation time was 10800 seconds in the simulation with sprinklers.
