Time-Dependent Valuation (TDV)

The following documents explain the development of Time-Dependent Valuation (TDV), the new method for valuing energy in the performance approach in the 2005 Building Energy Efficiency Standards. Under TDV the value of electricity differs depending on time-of-use (hourly, daily, seasonal), and the value of natural gas differs depending on season. TDV is based on the cost for utilities to provide the energy at different times.
