comparison, many old boilers have AFUE ratings of only 5565%.3 Today, there are many residential natural gas furnaces and boilers that have AFUE ratings of 95% or higher. AFUE ratings do not apply to the larger boilers used in multi-family apartment buildings and commercial buildings. These boilers are typically rated for efficiency
welded connections given the building and occupancy type. Section 4 Overview of Labor, Material, Equipment, Indirect Costs and Approach to Mark-ups The example in this technical paper will be a straight-forward demonstration of how to takeoff and develop pricing for a two-story steel framed medical office building.
For most parts of the country, peak heating load only occurs for a few hours per year, so system can be sized at 60-70% of peak load and still meet 90% of annual load. Things to consider when doing a feasibility study include: peak and annual load, current fuel use and cost, building area available, delivery routes and access; O&M staff available.
