CoBAM is organized around the structure of the commercial buildings sector described in Martinez-Moyano et al.
We have not yet included a structure to simulate users (or their behavior), developers, capital providers, or community and regulatory interests in CoBAM. We also have not yet included the exogenous influences of geographical constraints, business development forecasts, residential buildings stock status, political and regulatory outlook, population and job market profiles, or DOE and energy efficiency programs (other than those captured in the technology offerings).
CoBAM is developed in the open-source Repast Symphony environment (see http://repast.sourceforge.net/).
In CoBAM, we create a population of buildings based on normative building descriptions (Torcellini, Deru, Griffith, Benne, Halverson, Winiarski and Crawley 2008).
In CoBAM, we implement a physics-based, normative building energy model to estimate the EUI (in kWh/m2/year) of buildings.
In CoBAM, the energy efficiency of building equipment degrades every year.
In CoBAM, three input parameters are considered in the degradation function: the energy use intensity of lighting fixtures [(ADR.sub.light], unit: [W/m.sup.2]), the seasonal energy efficiency ratio (SEER) of cooling systems [(ADR.sub.SEER], unit: kW/kW), and the efficiency of heating systems [(ADR.sub.heat], unit: kW/kW).
Additional systems will be added to CoBAM for future research efforts.
