In this argument, the arguer claims that Rockingham's century-old town hall should be torn down and replaced by the larger and more energy-efficient building. To substantiate his view, the arguer points out that the old town hall is too small and it is very costly to heat or cold it in different seasons. However, the argument is untenable for several critical flaws.
First all of, the mere fact that the new building would cost less per square foot to heat and cool than the old hall does not necessarily imply that the total cost will decrease. Because the new building is much larger than the old one, it is likely that the product of whole area and the cost per square is enormous. Otherwise, the overhead expenses would be higher than the old one’s. Thus there is no guarantee that the new, larger building would be more energy efficient and the cost will be low.
In addition, the arguer fails to consider other methods that can save money. For example, they can replace all the old, less efficient air conditions by some more efficient, powerful ones to save the money. Moreover, the arguer does not consider the negative influence that is caused by pulling down the old building. Now that it is a century-old town hall, maybe it is not wise to replace it by a new one because of its history value. It is the witness of the history and people could learn much from the past. Thus we may comfortable to conclude that it is very worthy of being preserved.
Finally, there is no warrant that rent out some of the space in the new building is a good idea, because it is not sure whether there will some one would rent it. Thus if there is no one want to rent it, it will be costly to keep it and more or less it will be an encumbrance.
All in all, the argument is not well reasoned because the reasons cited in the analysis can not lend strong support to what the arguer maintains. To make it better logically acceptable, the arguer would have to demonstrate the total cost of the new hall is less than the old one, and it will be exactly profitable to rent out some of the space in the new building. Additionally, we would need more information about the history value of the old one.
