The thickness of the sheet metal What is neutral axis in sheet metal.Percentage of carbon content in the sheet metal.Material composition in the sheet metal.To compression this compression and expansion, bend allowance exists so that we get the correct length of the flat part.īend allowance depends on the following factors. On the other hand, the outer portion ( Covered by T-δ) is under expansion that always tries to elongate the part. When a sheet metal forms a bend, the inner portion ( Covered by δ) is always in compression that reduces the part length. July 2010.Δ= Distance between the inside radius of the bend and neutral axis “ Utility Allowance Model Final Report.” June 2003. “ Utility Model Evaluation.” September 2005. “ Final Report on HUD52667 Spreadsheet Update.” February 2007.Ģrw+di. “ Detailed Tables.” (Appendix 1 of the HUD Utility Model (HUSM) Rebenchmarking report), December 2012. “ Summary Report: Heating and Cooling Trend Adjustment” (Appendix 2 of the HUD Utility Model (HUSM) Rebenchmarking report). “ Summary Report: ENERGY STAR Adjustment for HUD-52667 Spreadsheet Model” (Appendix 3 of the HUD Utility Model (HUSM) Rebenchmarking report). “ HUD Utility Model (HUSM) Rebenchmarking.” December 2012.

“ HUD Utility Model (HUSM) Rebenchmarking.” June 2013. “ Final Model Development Report.” July 2015. The web-based version of the HUSM is available at: A Microsoft Excel-based version of the model is also available and can be downloaded here.

incorporating a factor adjustment feature Īn instructions document has been developed to provide a step-by-step explanation on how to use the model.

refining the model’s heating consumption estimates.

incorporating additional green discounts (i.e., LEED and Significant Green Retrofits).

updates to the water usage estimates based on U.S.

updating the underlying degree-day data with the latest NOAA 30-year weather data (1981-2010).

providing users the ability to generate allowance estimates based on zip code, in addition to PHA.“floor” and “ceiling” values for all utilities types.Updates to this version of the model include: This version of the model is primarily based on the 2009 Residential Energy Consumption Survey 1 (RECS) dataset that is published by the Energy Information Administration (EIA) of the Department of Energy (DOE). The current HUSM is a web application that uses correlations and regression techniques to calculate allowances for end-uses, as specified on form HUD-52667 (Allowances for Tenant-Furnished Utilities and Other Services). The Office of Policy Development and Research (PD&R) has developed the HUD Utility Schedule Model to provide a consistent basis for calculating utility schedules.
