BPI: Qualification Of Whole-House Energy Savings Predictions By Calibration To Energy Use History
Building Performance Institute standard ANSI/BPI-2400-S-2012 Standard Practice for Standardized Qualification of Whole-House Energy Savings Predictions by Calibration to Energy Use History, specifies a process for the calculation of standardized predicted savings: the difference (delta) between the modeled energy usage before and after an upgrade using approved building energy use simulation software. The process uses actual home energy bills to predict savings, and provides a set of standardized operating conditions to be used in the final calculation of predicted savings. The standard applies to existing detached single-family dwellings and townhouses that meet the specific criteria detailed in the scope. (PDF)

BPI: Standardized Qualification of Whole House Energy Savings Estimates
Building Performance Institute standard BPI-2400-S-2011: Standardized Qualification of Whole House Energy Savings Estimates is now available for public comment. IT specifies a process for the calculation of standardized estimated savings: the difference (delta) between the modeled energy usage before and after an upgrade using approved building energy use simulation software. The process uses actual home energy bills to estimate savings, and provides a set of standardized operating conditions to be used in the final calculation of estimated savings. The standard applies to residential buildings of 4 units or less.

Home Energy: Energy Modelling Old Homes
Home Energy magazine says the biggest errors occur in modeling estimates of energy use in older homes; usually post-retrofit energy use is pretty close to modeled estimates, but pre-retrofit use is dramatically overestimated because of poor assumptions, biased inputs, and bad algorithms.

US DOE: Building Component Library For Modeling Data
US Department of Energy online Building Component Library is a searchable library of energy modeling building blocks and descriptive metadata. Users can use the freely available and uniquely identifiable components to create energy models and cite the sources of input data, which will increase the credibility and reproducibility of their simulations. It contains components which are the building blocks of an energy model. They can represent physical characteristics of the building such as roofs, walls, and windows, or can refer to related operational information such as occupancy and equipment schedules and weather information. Each component is identified through a set of attributes that are specific to its type, as well as other metadata such as provenance information and associated files.
