[EnergyPlus_Support] V2 Features

The following features will be available in V2.0, 
released in mid-April 2007.  There may be some 
others at the last minute as well.  If we are 
updated, I will update the list.

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 utilities­Basement, 
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.
