I am working on a mixed use project that has offices, retail residential and higher education spaces in the mix. We are trying to estimate anticipated energy loads - both annual usage and peak demand for each space type (chilled water, steam, natural gas and electricity). I have reasonably good data from CBECS & LBNL on annual energy usage. The roadblock is in the peak demand numbers.

Does anyone know of a good [credible] published resource for peak demand numbers for these building types?

Thanks for your help
