IES VE 2012 Feature Pack 01 Release Notes VE 2012 Feature Pack 01 Changes General Creating a new project will delete any existing files with the same name [ID-0049609]: If you create a new project with the same name as an existing project, any existing files will be deleted prior to the creation of the new files so the existing project is completely overwritten. Report "Save as Text" only saves relevant text [ID-0047690]: When saving a report as a text file the XML data is no longer written out. Tabular Room Data and BTM are refreshed following ApPro edits [ID-0049584]: Tabular Room Data and Tabular Building Template Manager will both be refreshed to reflect any changes that are made in ApPro.

ModelIT Tidy key-in updates [ID-0050663]: The Tidy key-in can no longer be used on composite spaces. It can only be used on single spaces. Subtract function updated [ID-0049157]: Trying to subtract an invalid zone will show an error message. The area to be subtracted must bounded the zone. ModelIT status grid improved for different font and DPI settings [ID-0049560]: The ModelIT status grid dialog bars will be sized to allow the grid text to be visible for a range of font sizes and DPI settings. Trim can only be used on zones that intersect [ID-0047959]: The trim function can now only be performed on zones that intersect each other. "Fit view" accounts for components outside the zone [ID-0049422]: The "Fit view" option takes any components into account when scaling to the zone. Stay in Component mode after finalizing component [ID-0049332]: After finalizing a component it will remain in component view rather than returning to the model level. Fix key-in precision updated [ID-]: You can use the “Fix” key-in to set precision to 3, 4, 5 or 6 decimal places. In the key-in box type “fix=x” to set the precision.

Apache View Adjacency Temperature Profile input character limit updated [ID-0048272]: The Adjacency temperature profile dropdown has been updated to allow profiles with names greater than 60 characters. Tabular Room Data: Error message when changing Thermal Template no longer displayed [ID-0052211]: Changing thermal template via Tabular Room Data without having first went into VE Compliance will no longer result in an error about the BL2 file not being found. Tabular Room Data: Crash prevented when adjusting % Saturation values [ID-0050040]: A problem could occur when the template value for the setting would cause an invalid value to be applied (based on the value of the opposing setting). This has now been prevented.

IES VE 2012 Feature Pack 01 Release Notes ApPro Assigned daily profile type uneditable after importing weekly profiles [ID-0051422]: After importing a weekly profile, the type (modulating or absolute) of any existing daily profiles is only editable if they are not referenced by any weekly profile. Profiles use correct references to weather variables [ID-0051763]: References to the weather variables; outside RH, outside moisture content and outside wetbulb temp are correctly used in formula profiles.

Constructions Prevent over counting of constructions in use [ID-0050326]: When reporting constructions in use only one model variant will be used. This will prevent duplicate constructions being reported for the model variants for example in the ASHRAE 90.1 AppG PRM Reports. Displayed EN410 g-value updated when glazing properties are edited [ID-0050078]: When changing the transmittance of the glass the EN 140 g-value will be updated correctly and will match the value in the derived parameters dialog. Shading device profile setting retained [ID-0049136]: The shading device percentile profile group value will be retained on re-entry to the Construction Database. Previously, if the shading device profile was set to 'None' it would be set as 'off continuously' on re-entry. Specific Heat Capacity reported in APcdb when using IP units [ID-0049919]: In the Construction Database, when using IP units, all system and project materials have values displayed for specific heat capacity. Condensation Analysis dry bulb and dew bulb temperatures corrected [ID-0050005]: In the Condensation Analysis dialog the inside surface dry bulb and dew bulb temperatures are reported correctly. Ground contact U-value adjustment validation improvements [ID-0050267]: Further validation done to the Ground contact U-value adjustment dialog to prevent divide by zero errors.

ApacheHVAC Low resolution graphics option added [ID-0050853]: A menu option which switches the canvas display from the current alpha-blended icons (which are invisible on certain systems) to a set of non-blended, lower resolution icons is added. This can be accessed via the menu option - ApHVAC > Options > Use low resolutions network graphics. Save button on main toolbar also calls HVAC save function [ID-0048933]: The Save project button in the main VE toolbar now also saves the HVAC network. HVAC check network improvements [ID-0025569]: When performing a network check, any ductwork running straight through a multiplex, without a component, will be highlighted and an error message shown. Warning when Multiplexes connected by only Ductwork [ID-0022145]: It is invalid to have multiple Multiplexes connected only by ductwork, at least one component or junction should be present between them. When the Check Network button is clicked and this scenario is sensed a warning message is displayed giving the IDs of the Multiplexes and also highlighting them on the network. Fix for boundary nodes of multiplexes containing a single component [ID-0051172]: Incorrect nodes are occasionally written out at multiplex boundaries causing the simulation to fail. This would primarily affect multiplexes containing a single component. A fix to correct this is now in place. page 5


IES VE 2012 Feature Pack 01 Release Notes Copied system level components reference correct system [ID-0050859]: After copying a system, all the system level components (components outside the multiplex) will reference the correct system. Systems with DCV sizing improved to ensure Active Chilled Beam primary airflow meets exhaust air [ID-0051748]: The Loads data spreadsheet is improved so that where a system has Demand Controlled Ventilation the Active Chilled Beam primary airflow (Controller MC10) is adjusted to ensure it always meets exhaust air flow. Loads Data spreadsheet update for systems 3 and 4 [ID-0050782]: The Loads data spreadsheet has been improved to increase stability for Prototype systems 3 and 4. The default coil temperature reset value will automatically be set to a larger value (greater reset range) when Constant Air Volume is used rather than Variable Air Volume airflow. Use chilled/hot water loop supply temperature checkbox persists [ID-0050830]: The checkbox on a Radiator or Chilled ceiling Control dialog to "Use hot/chilled water loop supply temperature" will retain its status when it is ticked/unticked and room component behaves accordingly. Fixed auto-assignment of ASHRAE 90.1 DX/AAHP plants in PRM baselines [ID-0051936]: The selection of which type of DX or AAHP to assign to a given system type is now using the updated format. Predefined AAHP missing/incomplete error not shown if duplicates present [ID-0050819]: Importing a system with "All" plant options set will duplicate the predefined Air-to-Air Heat Pumps. During Room sizing these duplicates are ignored so the "Warning: Air-Air Heat Pumps are incomplete or missing" message will not be shown. Adding controller to multiplex allowed only in global edit mode [ID-0049416]: In order to add a controller to a multiplex you need to be in Global edit mode. Multiplex data table edit improvements [ID-0050664]: Editing values in a multiplex data table using the paste function will no longer revert manually edited values back to the previously set value.

Heat transfer loop dialog corrections [ID-51915]: When editing an existing heat transfer loop with the loop configuration set to Primary-Secondary, the heat transfer loop dialog will populate the edit control and combo box for the secondary circuit. Condenser mass flow calculation and condenser entering temperature overload adjustment corrections [ID0051623]: The Condenser water loop entering condenser temperature is now adjusted when the cooling tower is overloaded. This will effect computation of chiller operating performance. Dewpoint temperature control permitted for DX coil [ID-0051274]: Dewpoint temperature control is now enabled for DX cooling. Maximum storage tank temperature for Solar Water Heater updated [ID-0051395]: The maximum storage tank temperature set for the Solar Water Heater on the Hot Water Loop is no longer restricting the SWH. The SWH can now make full use of its heating potential.

Vista Vista Compliance report updated for Shell and Core buildings [ID-0049028]: For Shell and Core buildings only rooms ticked as part of the core area will be included in the Vista compliance report.

VE Compliance Export as 6.1.1 model disclaimer updated [ID-0051100]: Following note added to disclaimer: NCM Templates may be downgraded and so room data derived from these templates, including Casual Gains and Air Exchanges, will be affected. In those instances we advise users to verify changes to room data. NCM Template upgrade improvements [ID-0051099]: When opening a model created in an earlier version of the VE, if there are any NCM templates with invalid ID's, these will be upgraded correctly and a file containing any affected templates will be created and stored in the project folder. Where this occurs a message will be displayed to inform the user. Demand Controlled Ventilation input displayed in EGA when Thermal Template has System set to None [ID0044322]: When a room is assigned a Thermal Template with the System set to None, the Edit Group Attributes dialog will display the Demand Controlled Ventilation input options. Can remove Air Exchanges in any order [ID-0048520]: You can now remove air exchanges in any order without receiving any error messages. Possible to enter a negative value for "Rating with improvements" [ID-0044366]: For a Section 6 EPC it is possible to enter a negative value for "Rating with improvements". District Heating data written to brukl.inp file [ID-0041013]: When the Actual Building system has District Heating as a heat source the energy value will be written to the brukl.inp file. This is reported as KWH/M2-DISTRICT-HEATING. Generated energy written out to ApacheSim brukl.inp [ID-0050438]: When a Renewable technology is present in a project the brukl.inp generated by ApacheSim will write out the generated energy as KWH/M2-DISP. KWH/M2-SUPELEC value written to BRUKL.inp from Apache corrected [ID-0050435]: The Actual Building KWH/M2SUPELEC value written in the BRUKL.inp from an ApacheSim has been updated. It no longer includes Equipment Energy. E.g. for a simple model set up with Natural Gas as the Heating fuel then SUPELEC should only account for LIGHTS energy and Auxiliary Energy + COOLING if a Cooling system.

FlucsPro/DL Sky view threshold report updated [ID-0051096]: Sometimes when viewing the sky view threshold report incorrect values would be reported for the area and percentage area. This has been corrected to always display the correct values. page 7

Constructions Assigning "Internal Floor/Ceiling" constructions assigns to the ceiling of the highlighted zone [ID-0050476]: When assigning constructions of the type "Internal Floor/Ceiling" the constructions are assigned to the ceiling of the highlighted zone only.

ApacheHVAC System 9 FCU Fan Speed selector corrected in Loads Data spreadsheet [ID-0050709]: In the Loads Data spreadsheet the dropdown menu selector for 2-speed vs. VSD fans in fan-coil units on the System 09 tab now sets the correct proportional bandwidth value. Timed Hot water supply temperature set point defaults to "constant 0" [ID-0050577]: When the Hot Water Loop supply temperature set point uses a timed profile the profile will default to "constant 0". Timed source water temperature profile defaults to “constant 0” [ID-0050514]: When the Water source heat exchanger uses a timed profile for the source water temperature the profile will default to "constant 0". Systems with Demand Controlled Ventilation sizing improved to ensure minimum outside air ventilation meets exhaust air [ID-0050710]: The Loads data spreadsheet is improved so that where a system has Demand Controlled Ventilation the minimum ventilation (Controller MC3) is adjusted to ensure it always meets exhaust air flow (room minimum ventilation will take value of 30% of ventilation unless Exhaust air flow is greater in which case the minimum is increased to meet this). Further, to ensure the System total of all minimum ventilation rates meets total Exhaust a check is added in Cell S26 to display the Ratio of System Total Minimum OA airflow for Ventilation (MC3 column AW) to System Total Exhaust Airflow (MC6 column BJ). Where this does not meet total exhaust a System loads calculation will fail with "Negative flow" error so the cell is formatted to highlight this within the spreadsheet giving an opportunity to address the problem prior to leaving spreadsheet and assigning system parameters and zone sizing data. Multiplex corruption error reporting improvements [0050808]: Error reporting in Apache, where multiplex corruption has occurred, now details the affected multiplex name and layer.

ASHRAE 90.1 App. G – PRM PRM Baseline model retained on upgrade [ID-0050372]: The PRM Baseline model is retained when you upgrade an existing project to VE 2012. page 9

IES VE 2012 Release Notes VE 2012 Changes ApacheHVAC Proportional Controller must have a sensor specified [ID-0046538]: A proportional controller must have a sensor specified as either "set point" or "proportional control", scenarios where it was possible to specify neither of these have been removed and a warning is displayed if attempt to uncheck both. Room Units Proportional Sensor room assignment stored correctly when add layers to a multiplex [ID-0045886]: When layers are added to a Multiplex which includes room units with proportional sensor assigned to a room, the new layers will include a proportional sensor referencing the room for that layer and this is retained when close and reopen the network. Delete Prototype System can be Undone [ID-0031111]: Undo (via Edit menu item or Ctrl+Z keyboard shortcut) after deleting a Prototype system will reinstate the complete Prototype system (including boundary) in the HVAC network. Autosizing of MC8 controller setpoint [ID-0042051]: In Zone sizing of System types 3 and 4, only the Setpoint value within the MC8 controller will be linked to the Loads Data spreadsheet. Selection via browser [ID-0038820]: Selection of HVAC network components via the browser tree now works consistently, with the exception of unassigned or adiabatic room components (i.e., any that are not yet associated with a space in the model). Edit Multiplex scrollbar [ID-0032024]: In the Edit multiplex dialog, the behaviour of the scrollbar is improved. Boundary line visibility during zoom [ID-0033024]: Boundaries of both multiplexes and prototype systems remain visible during zoom operations. Part load Heating performance curve [ID-0042030]: In the Part load curve Heating plant, the bottom row of the performance curve can be removed without error. Mouse panning to outside of HVAC window [ID-0026690]: When panning with middle mouse button, going outside the HVAC window boundary no longer disables component selection. Room Units' on/off and proportional sensor routes now independent [ID-0016105]: In Room Units, the On/off sensor checkbox is reinstated, and also does not have to be checked. In other words, the On/off and Proportional sensor routes are now independently settable. Upgrade of legacy chillers [ID-0048065]: Upgrading an old non-looped chiller to a Chilled water loop now will not crash. Fan oversizing factor [ID-0035511]: Fan components can now be given an oversizing factor. Import Library on low-resolution screen [ID-0040719]: Import from Library is usable on a screen of the minimum supported resolution (1152 x 864). Display of electric watercooled chiller sizing status [ID-0032105]: When a sized parameter in an Electric water cooled chiller is manually edited, the number field colour reverts to black. Display of controller sizing status [ID-0047354] [ID-0042055]: When sizable parameters in a controller are either autosized or manually edited, the colours of the number field and the "A" label are both updated correctly. Display of part load chiller sizing status [ID-0039230]: When a part load curve chiller is autosized, the colours of the "A" labels update correctly both at initial sizing and at subsequent manual edits. page 12


IES VE 2012 Release Notes Multiplexed active ducts in simulation [ID-0036880]: Multiplexed active ducts are now simulated correctly on each layer. Pump usage in Generic heat source [ID-0047312]: The pump usage % in a Generic heat source is now correctly applied. Unmet load hours during unoccupied times [ID-0046798]: HVAC profiles have been adjusted wherever necessary to prevent excessive unmet load hours during unoccupied times. Correct default DHW Heat source [ID-0046437]: All baseline PRM systems with Electrical heating now default to have DHW / SHW served by the Heat source "Baseline SHW heating plant (electric)-set eff.per 90.1 table 7.8; set SL in apsys" as per ASHRAE table G3.1.

ApacheLoads ASHRAE Loads applies Daylight Savings Time for southern hemisphere locations [ID-0046569]: For southern hemisphere locations where Daylight Savings Time is applied over winter (default 1 hour from October to March) ASHRAE Loads results show the correct solar gains.

ApacheSim Shell & core building load variables exclude shell rooms [ID-0034883]: At building level shell & core building load variables exclude shell rooms.

ApLocate Simulation Calendar settings are fixed and cannot be edited [ID-0033413]: When APLocate is launched in VE Compliance, the Simulation Calendar settings are fixed and cannot be edited. Correction to Latent Cooling Loads when no cooling provided [ID-0044499]: When the temperature of a room air supply (which may be an air exchange or an air supply from an Apache System) is set to follow an absolute profile, there may be dehumidification of the supply air if the implied cooling (from the outside air condition) raises its percentage saturation near to 100%. Previously the maximum % saturation was set at 90% to represent the typical condition leaving a cooling coil, but this could give rise to unrealistic dehumidification loads when the temperature drop was small. This model has been replaced by one in which the off-coil (supply) % saturation is set to the higher of 90% and the outside air % saturation.

IES VE 2012 Release Notes ApPro Correction to Latent Cooling Loads when no cooling provided [ID-0044499]: When the temperature of a room air supply (which may be an air exchange or an air supply from an Apache System) is set to follow an absolute profile, there may be dehumidification of the supply air if the implied cooling (from the outside air condition) raises its percentage saturation near to 100%. Previously the maximum % saturation was set at 90% to represent the typical condition leaving a cooling coil, but this could give rise to unrealistic dehumidification loads when the temperature drop was small. This model has been replaced by one in which the off-coil (supply) % saturation is set to the higher of 90% and the outside air % saturation. Create new profile improvements [ID-0043731]: After pressing the New button, the new profile is no longer deleted if you cancel the edit dialog. The New button now always creates a new profile, and cancelling the edit dialog only undoes any edits to the new profile - it does not undo the creation of the new profile. This is to guard against the situation where new profiles can already be referenced from other profile dialogs before closing the new profile dialog. Daily profile graph colour retained [ID-0031766]: The graph colour for the daily profile is now saved globally.

APView Edits made to Room Data do not lead to missing profiles [ID-0048121]: When edits are made to PRM Baseline or Proposed Room data (via room data, edit group attributes or tabular room data) the model is not corrupted and no profile references are lost. Tab Edit - Error message for no valid Room ID updated [ID-0041505]: When importing data, if no valid Room ID is found in the *.txt file or if the room is not currently selected then an error message will be shown highlighting these rooms. Room Data dropdown style consistent [ID-0042026]: The Room Data dialog dropdown fields have been updated so that they have a consistent style. Tab Edit - Actions to "select all rooms" added [ID-0041509]: “Select all rooms” function added to the Action menu. Tab Edit - Exported filename prefixed with [TB] [ID-0041504]: Exporting a file in Tab Edit will prefix the default filename with "[TB]".

Constructions Construction can't be deleted when referenced in a construction template [ID-0042555]: When a construction is referenced in a template then it can no longer de deleted. "High usage entrance door" added to Construction Database NCM Type dropdown [ID-0049124]: In CDB for the purposes of UK regs Compliance it is possible to represent a glazed door as a Window and then use the NCM Type option (Regulations section) to class the window as a door for the purposes of the criterion 2 U-value check. The NCM type list now includes the "High usage entrance door" option. Visible Light Transmittance value editable after saying Yes to the VLT default value message [ID-0048133]: For any new project if you edit a glazed constructions Visible Light Transmittance to any value that is not 0.76 when you exit CDB a warning is displayed and you can choose yes to set it back to 0.76. Any time you subsequently edit VLT and exit CDB the edited value will be retained. SBEM "Metal cladding" parameter visibility [ID-0035797]: SBEM "Metal cladding" parameter is now only displayed in the Opaque construction dialog if the user has licences for UK compliance methods.

page 14


IES VE 2012 Release Notes U-value Adjustment dialog Rounding improvements for ground-contact floor area [ID-0035764]: If the actual floor area is an even number in IP units, for example, 10,000 ft2, then the dialog reports this as a slightly smaller number, in this example, 10,000 becomes 9,999.996. This has been corrected. Glazed construction dialog shows frame width in mm or in [ID-0048288]: In the glazed construction dialog the frame width was previously shown in m or ft. It is now shown in mm or in (depending on the units set). "Apply current standards to ALL" action removed [ID-0047694]: "Apply current standards to ALL" action has been removed from the Project Construction Tools menu.

FlucsPro/DL Room window transmittances not replaced by 100% when other rooms taken into account [ID-0041446]: Corrected the way windows from other rooms are used by only using them as obstructions. Model browser is refreshed after Working Plane is deleted [ID-0040204]: After deleting a Working Plane the Model Browser is automatically refreshed to reflect this change. Daylight Factor table aligned to right of model [ID-0033607]: The Daylight Factor table will always be aligned to the right hand side of the model for all view rotations. Threshold contour Close button does not save changes [ID-0041231]: The Filled threshold contour dialog Close button does not save changes.

Gaia Climate Metric report units retained [ID-0045885]: In the climate metrics report the correct units are shown and retained when switching between Metric and IP units. Gaia Daylighting settings updated [ID-0046308]: Reflections set to "Full inter-reflections" and Sky Model set to "CIE overcast sky". BREEAM HEA1: Check B room area improvements [ID-0046806]: Only the area of the rooms passing check B are included in the total area. We have changed the totalisation of the two B checks (uniformity and minimum DF): previously the complying areas for each room were all counted and if the total percentage area was > 80% this was deemed a pass. Now the complying areas for each room are only counted if the room itself passes. Building Metric Set building type step updated [ID-0046852]: The "Set building type" step in the Building Metrics navigator now opens the "Set building type" dialog rather than the Building Template Manager. System can't be deleted when referenced in Thermal Template [ID-0042380]: It is not possible to delete an Apache system that is referenced by a room or by any thermal template in the project.

General Set grid alignment button disabled when project has no geometry [ID-0041809]: The Set grid alignment button is disabled until the model contains geometry. Tabular Room Data window retains its size after VE is restored [ID-0042557]: The Tabular Room Data window retains its previous state after the VE is minimised and then restored.

LightPro Zoom functionality improved [ID-0015718]: Zoom functionality improved when visualising the photometric web in the Viewer.

ModelIT Storey index improvements [ID-0042448]: When a model is built "top down" the Room story index now accounts for this and will be shown correctly. Tidy key-in improvements [ID-0046643]: Using any of the tidy key-ins (tidy, tidymirror, tidysurfs and tidyunbound) will now no longer automatically apply inner volumes to the zone. Intersections not reported for zones drawn inside "donut" shaped room [ID-0042691]: When you create a "donut" shaped room e.g. a zone with a subtracted second zone to create a hole. You can place a zone in the centre of the newly created hole and will not receive any intersection error. “Merge” and “Subtract” tool improvements [ID-0039649]: The “merge” and “subtract” tools have been improved and they do not change internal walls to external walls. The default construction will be applied to internal walls and will be shown correctly. Subtracting zones improvements to avoid coincident vertices warning [ID-0044520]: Additional refinement when subtracting zones to avoid coincident vertices warning. Number pad enabled for use in ModelIT [ID-0038434]: You can now use the number pad with the key-in box in ModelIT.
