[EnergyPlus_Support] Version 2.1 release

["Crawley, Drury" <Drury.Crawley@xxxxxxxxxx>]

Yes, we're much later than we planned on getting Version 2.1 out this
time.  But we wanted to ensure that it was as bug-free as possible.  We
are currently wrapping it and if no more issues arise, it should be
available early to mid next week.  We'll send a message to this list as
soon as it's available.  

To give you a preview, here's part of the new features list:
 

Natural and Mechanical Ventilation     

*         Added new system availability manager to allow system-level
control of hybrid ventilation systems.

 

HVAC 

*         Added water-cooled condenser capability to refrigeration
compressor racks for useful heat recovery. 

*         Chilled and hot-water coils can now be used in the outside air
system to preheat or precool outside air.

*         New desiccant dehumidifier with additional capabilities and
flexibility compared to the existing solid desiccant dehumidifier model.

*         Water side economizer (including simulation of integrated and
non-integrated water side economizers).

*         Packaged terminal air conditioner (PTAC) added to model a fan,
DX cooling coil, and a gas, electric, hydronic or steam heating coil
serving a single zone.

*         Multispeed heat pump with up to four discrete speeds for both
cooling and heating.

*         Heat losses (and gains) from plant piping.

*         New and updated Compact HVAC objects:

o        Compact HVAC chilled water coils now use the COIL:WATER:COOLING
model by default, COIL:Water:DetailedFlatCooling can be selected as an
option.

o        Compact HVAC unitary system now supports the draw-thru fan
placement option, and allows a schedule for the supply fan operating
mode (continuous or cycling).

o        New Compact HVAC options for dehumidification and
humidification controls for unitary and VAV system types.

o        New primary-secondary loop options for Compact HVAC chilled
water loops.

o        Compact HVAC expanded to support specification of outside air
as a combination of flow/person, flow/area and flow/zone.

o        Compact HVAC baseboard heat option added for unitary and VAV
zones.

o        New Compact HVAC objects for unitary heat pump, unitary VAV,
packaged terminal air conditioner, and packaged terminal heat pump.

  

Output 

*         New tabular reports for surface shadowing, shading, lighting,
HVAC sizing, system and component sizing, and outside air.

*         New Report:SurfaceColorScheme allow users to select their own
colors for building elements in the DXF output.

 

Utilities            

*         WeatherConverter now produces KML output (for Google Earth) of
latitude, longitude, elevation, and a few climate statistics for
locations in a list processing run. 

*         Add comma delimited form of CLM (ESP-r Ascii files) conversion
to WeatherConverter.

*         WinEPDraw produces in new default colors. 

            

Documentation and Guides

*         Completely rewritten Getting Started manual provides more
hands-on example exercises and other information for getting up to speed
on EnergyPlus.

*         Input/Output Reference and Engineering Reference updated and
extended for all new features and updates. Total documentation now
exceeds 3500 pages.
