Often, there can be uncertainly relative to the need for building new facilities or renovating existing facilities. Existing and aging buildings may not be serving the needs of their occupants in terms of space, technology, and energy efficiency. In these circumstances, the benefits and cost of building a new facility may outweigh the expense of investing in extensive renovations. When there is uncertainty about which option to choose, a feasibility study can examine the positives and negatives relative to function, energy efficiency, and overall building use. We can also examine the feasibility for the construction of new structures in terms of potential use to a community or governmental agency.
