Where do cost values come from?
analysis.tool has cost values for various building products, building systems, and operational/utility costs. These values come from a few different places:
For Exterior Enclosure and Roofing products and assemblies, costs come from analysis.tool's Product and Assembly Database. This database contains generic product costs, based on national average cost. The methodology used to derive the costs is as follows:
National cost databases are reviewed first for a general understanding of cost for materials, labor, equipment, overhead and profit
Next, material costs are cross-checked with direct manufacturer pricing from cove's product partners, when applicable
Additionally, labor costs are cross-checked with industry input and statistics from applicable publications to reflect today's labor cost
All costs are cross-checked again with industry reports and publication. When applicable, material and labor costs are escalated using a factor determined by cove's market study.
For other building products and systems in analysis.tool, costs are provided directly by our Manufacturer Partners, which include regional price variations linked to the user's building location. cove also partners with strategic owners, pre-construction teams, and other industry leaders, of whom have given analysis.tool access to multiple national databases for construction costs. These numbers are used to estimate costs for the rest of cove's non-manufacturer-provided inputs and an extensive utility cost database. Once assembled, all cost values are meant to give users an apples-to-apples comparison for understanding the benefits and/or drawbacks of each building's designs and/or performance strategy. So that when you start to discuss the project with the design team or a client, you can be in the right ballpark for costs when capable of identifying cost-effective strategies and unnoticed areas of opportunity. If users would like more personable and region-specific costs, analysis.tool allows users to add, delete, and edit existing cost values through different tools. Also, users are welcome to invite cost estimators into a project, to edit and/or validate the input costs.
Where to see cost values?
Cost values are displayed throughout a user's project. They will play various roles in your project and can be seen in the following cases.
In the Assembly Builder as unit costs, for Exterior Enclosure and Roofing assemblies and associated products.
As Input Variables (Utility Rates or Product Costs). Costs that are required to output cost-related results are always automated for the users at the onset of creating a new project. These values are based on your building location and use type. At any moment, users are free to edit the cost input to better estimate a region and scenario's best cost value for this category. Input Cost Variables can be found in the Baseline Energy>General>Utility Rates, and Change Options pages in analysis.tool.
As a result. Costs are used to give users ball-park ideas of the whole building costs.
As Cost Premiums in the Optimization Page. Each bundle option will have a cost premium which is listed. This sum is meant to be added to the baseline cost to get the total cost of your bundle package.
As a Whole Building Baseline and Optimized Costs in the Optimization Page. The baseline cost is all the code minimum (baseline) options taken together with the geometry. So any option that has a cost/area value is multiplied properly to compute the cost. We do not need to know the overall building cost since it’s a decision-making tool and not a costing tool. The key is having something as a baseline and being able to see the impact/tradeoffs of different options.
COST FAQ
Does analysis.tool include general overhead and profit costs?
For exterior enclosure and roofing assemblies, a general overhead and profit is built into the unit cost.
For other products and systems, general overhead and profit is not automatically included. Users can modify the cost inputs in any section of the tool to include these additions on top of the automated cost per square foot, or total costs, provided by analysis.tool. For example, analysis.tool might estimate that a glazing product alone would be $0.75/sf, but if a user wanted to include overhead to the analysis, then they would need to identify how much additional cost/sf overhead would be, then add it to the product cost.
Does analysis.tool calculate first-costs?
Yes, but only for options being evaluated in analysis.tool. For example, analysis.tool currently lists a series of options where users can evaluate their building envelope, HVAC systems, PV options, and more, but no areas for users to include distinct categories like wood, concrete, steel, and finishes. So baseline and premium costs like those seen in the optimization tool, are the combined value of the bundle's components (ie. Wall, Windows, Roofs, HVAC system, Sensors, PV, etc.
Does the costs in analysis.tool include labor, operation, and maintenance costs?
For exterior enclosure and roofing assemblies, labor and equipment costs (together, called installed cost) are built into the unit cost.
For other building products and systems, the cost in analysis.tool only includes bare material cost. The user can decide to include these additions by adding onto the automated cost provided by analysis.tool to include labor.
Operation, and/or maintenance costs are not included as a part of the initial first costs. Operational cost is calculated as a part of the Baseline Energy result and is based on local utility rates and energy consumption.
Can I pre-load cost information into my analysis.tool project?
Yes. Many of our users have taken advantage of this capability. Reach out to your cove representative or to the live-chat support team, to get instructions and start uploading internal costs to analyze in analysis.tool.
