A 70-structure campus at the top of the Mississippi has been in need of a serious retrofit. We join this major project in progress, studying not only the design selections but the tradeoffs and sacrifices along the way.
Engineers are rethinking the standard engineering design paradigm, using lifecycle cost analysis (LCCA) to compare system alternatives that fulfill the same functional requirements but differ in terms of initial and operating costs.
Many engineers tend to avoid or delegate the nitty gritty of a ground source heat pump system, from soil moisture effects to building system (im) balance. It's time for designers to get in the loop.
