instruction: How many windows does the building have based on the provided paragraph?
context: The main entrance on the west side of the building faces North 14th Avenue. The building is fronted by a concrete porch with three steps leading to louvered double doors surrounded by windows. Panels of five lights each flank the doors, and above it a seven panel fanlight frames a sign with the club's name. Gabled returns supported by pilasters and a pair of Tuscan columns show a neoclassical architectural influence. Two four-light windows with green shutters are centered on either side of the door. Each of the windows has green two-panel shutters with cutouts of a full moon on top and a crescent moon on the bottom. The north and south side have four windows each, and the back of the building has three. The building is painted white and sheathed in clapboard except the four bottom courses covered with asbestos shingles. The porches and roof are green.
response: There are a total of 13 windows.
  
  The side of the house with the entrance has two four-light windows, the north and south side have four windows each, and the back of the building has three.
  
  Therefore, in total, the house has 2 + 4 + 4 + 3 windows or 13 windows.
