Re: [EnergyPlus_Support] Energy Plus v2.0

[Drury.Crawley@xxxxxxxxxx]

Scheduled release date is April 12th.  We're running through another
round of testing now and if no problems, we're still on schedule.

EnergyPlus Version 2.0 Available  April 2007

The next release of the EnergyPlus building energy simulation program,
Version 2.0, will become available in early April.  Two key new features
include green roofs and phase change material simulation.  We have updated
and extended capabilities throughout the existing building envelope,
daylighting, and HVAC equipment and systems portions of the program.  Some
of the new features include:

Data Sets
   ·  New materials data set based on ASHRAE 2005 HOF replaces legacy DOE-2
      and BLAST data.

Input
   ·  New weather data for 86 locations added:  69 in Australia, 16 in
      Canada, and 1 in Iran.  Weather data for more than 1300 locations are
      now available worldwide.
   ·  Example input files created for all new features (More than 225
      example input files now available).

Geometry/Window/Walls/Shading
   ·  Phase change materials (PCM) with variable thermal conductivity and a
      temperature-enthalpy function incorporated in conduction finite
      difference solution algorithm.
   ·  Users can now enter interzone surfaces once and EnergyPlus will
      automatically create the mirror interzone surface.

Zone Model
   ·  Zone Sizing modified to allow standards-type calculation of design
      outside air flow rates; allows min cooling and max heating limits on
      design supply air flow rates.

Natural and Mechanical Ventilation
   ·  Simple Ventilation object now reports air changes per hour
   ·  New options in UnitVentilator include no coil option and fixed amount
      for outside air control strategy.
   ·  AirflowNetwork model can now use Zone Exhaust Fan, OnOff supply fan
      and the DX heating coil objects.

HVAC
   ·  Evaporative condenser option added to existing refrigerated case
      compressor racks including availability schedule and basin heater
      with controls.
   ·  Draw-through fan configuration added for furnaces, unitary system and
      air-to-air heat pumps.
   ·  Different supply air flow rates now allowed for cooling, heating and
      when no cooling or heating is required in unitary, furnace and
      air-to-air heat pumps.
   ·  Common Pipe for Primary-Secondary systems provides an alternative to
      the Connection component object to model Primary-Secondary systems
   ·  Desiccant heat exchanger option added for the existing heat
      exchanger-assisted cooling coil object.
   ·  Stratified water heater model added.

Water Manager
   ?     Green roof simulation added.

On-Site Energy Supply
?     Combustion micro cogeneration model added.

Output
   ·  Report Variables and Meter Variables (rdd and mdd) separately
      reported and output as IDF.
   ·  Meters can now report cumulative value in addition to resetting at
      reporting time interval.

Utilities
   ·  New tab in EP-Launch added where users can launch other
      utilities?Basement, CalcSoilSurfTemp, CoeffCheck, CoeffConv, Slab or
      WeatherConverter.
   ·  IDF Editor now preserves the order of user IDFs and includes a large
      number of other new features.

Documentation and Guides
   ·  Input/Output Reference and Engineering Reference updated and extended
      for all new features and updates. Total documentation now exceeds
      3300 pages.

And many other enhancements and speed improvements throughout.
