Question

there are other considerations that should prevail over the

Answer 1

There are other considerations that should prevail over the utilitarian value of historic buildings.这个that引导的是主语从句吧,that是他引导从句的主语吧.因为从句中没有主语.

That 引导的不是主语从句,而是定语从句.

1）在 there be 表示“存在/有”的句型中,系动词后面的名词就是主语,如：

There are some trees in front of the building.楼前有几棵树.——some trees 是主语.

There seems(to be) something wrong about it.这件事好像有点不大对头.—— something 是主语.

2）that should prevail over the utilitarian value of historic buildings 中,that 是关系代词,指代先行词 considerations,如果用简单句表示就是 the considerations should prevail over …,意思是说“这种考虑应该胜过历史建筑的实用价值”.

整个句子的意思是：存在应该胜过历史建筑实用价值的考虑.
