Which sentence indicates that Allen did not use the proper standards for building a granary?

Allen, a farmer has built a granary to stock all the grains produced in his farm. He selected a location near his farm so that the cost and time of transporting the grains to the granary would be reduced. The room where the granary was built is very spacious. Allen hired a highly proficient technician to install the heating and cooling systems in the granary. The granary had only one window, which was blocked by a huge storehouse in front of it and there was no other source of ventilation. After some days, Allen realized that there are many beetles destroying his grains in the granary and many of the grains have started decaying.
