MF CHP Level 2 Tool, Beta 3
Promoting the use of combined heat and power (CHP) (cogeneration) in
multifamily housing is an initiative of the HUD Energy Action Plan. To help implement it, beginning in
2003 the Department of Housing and Urban Development (HUD) and the
Department of Energy/Oak Ridge National Laboratory (DOE/ORNL), executed
Interagency Agreements (IAA) to create feasibility screening software.
ORNL created, expanded, and validated a Level
1 preliminary screening tool (http://eber.ed.ornl.gov/HUD_CHP_Guide_version_2.1/)
that enables the owners of multifamily housing to consider the
feasibility (cost, savings and paybacks) for installing CHP. HUD gave
training and promoted its use by HUD staff, housing associations, and
building managers. In May 2010 ORNL created for HUD a more detailed Level
2 Multifamily CHP Analysis Tool (MF CHP) that adapts the Building,
Heating, Cooling, Power (BCHP) tool used for the Federal Energy
Management Program (FEMP) for use on multifamily buildings.
current working beta version (beta 3) was completed in May 2010, and can
be downloaded. Administrator privileges are required to install
this beta 3 tool.
The MF CHP Level 2 Analysis Tool is structured to perform parametric
analyses between a baseline building, typically a conventional building
without a CHP system, and up to 25 alternative scenarios with varying
selections for building mechanical systems and operating schedules.
Current version Beta version has only standard (or blended) single
utility rate for electricity ($/kWh), and Natural Gas ($/Therm). Users are asked to input the rate directly.
If user needs to do the calculation based on complex utility rates (e.g.,
peak demand, block charge, etc.), the hourly or monthly energy use can be
generated from the tool, and the utility cost can be calculated outside
of the toolkit using spreadsheet, etc.
