• of energy transmission in an exterior building envelope—walls,roofs, doors and windows, etc.) and energy usage by lighting and mechanical systems. A deficiency in the energy code(inadequate insulation,non-insulated window systems, improper air infiltration protection, etc.)reduces energy efficient operation and adversely affects building system durability;therefore, a deficiency in the energy code is considered to contribute to a condition requiring substantial renovation or clearance. Office evaluations—Following the on-site evaluation, each building was then reviewed,based on on-site data, age of construction, building usage and occupancy, square footage, and known improvements(from building permit data), and an assessment was made regarding compliance with current mechanical, electrical, and energy codes. A basic code review was also completed regarding the potential need for additional egress(basement stairways, for example), sprinkler systems, or elevators. Deficiency Cost—Costs to correct identified deficiencies were determined by using R. S. Means Cost Data and our professional judgement and experience. In general,where several items of varying quality were available for selection to correct a deficiency, an item of average cost was used, as appropriate for typical commercial or residential applications. Actual construction costs are affected by many factors(bidding climate, size of project, etc.). Due to the nature of this assessment,we were only able to generalize the scope of work for each • correction; that is to say that detailed plans, quantities, and qualities of materials were not possible to be known. Our approach to this matter was to determine a preliminary cost projection suitable to the level of detail that is known. This process was similar to our typical approach for a cost projection that may be given to an owner during a schematic design stage of a project. Costs to correct deficiencies were computed for each building and compared to the building replacement cost to determine if the 15%requirement was met. The total number of buildings determined to be"structurally substandard"by satisfying both the Conditions Test and the Code Test in this manner was compared to the total number of buildings in the district to determine if the 50%requirement was met. Reports on Structurally Substandard Buildings and Individual Building Summary Reports are available for review at the offices of SEH, City of Elk River, and Briggs&Morgan, St. Paul, Minnesota.
