3 <VE> <VE> Changes General SunCast shading file validation improved [ID ]: The SunCast shading file format is updated to include geometry data so that when running dynamic simulations linked to Suncast the shading file validation can be done prior to simulation and no warning or error messages are displayed when the shading file is valid. Note: If a model is opened in a version of VE earlier than then it will be necessary to regenerate the shading file in that version prior to running a simulation. ShowMe ShowMe crash prevented [ID ]: A runtime error was prevented when you attempt to generate a report in ShowMe. ModelIT Model Check Report improvements [ID ]: When two rooms are adjacent and the shared surface has a 100% hole, the ModelIT Check Report no longer flags up the adjacency as an unmatched adjacency Zero area. Tidy key-in improvements [ID ]: No longer receive an error when changing application after using the ModelIT key-ins; tidy, tidyunbound, tidymirror, tidysurfs and delsurf. Geometry name improvements [ID ]: When creating geometry, if you leave the zone name input blank the new zones are automatically named "zone 1", "zone 2" etc and the Room ID "ZN1_0000", "ZN2_0000" etc. SunCast Crash prevented when switching views [ID ]: Prevented crash when switching views while a SunCast shading calculation is running. Apache View Tabular Room Data: Installed Power Density edit enabled [ID ]: When the Input Mode is set to Lux (not from template), the Installed Power Density value is editable. Tabular Room Data: Setpoints "From Template" correctly applied [ID ]: If you have selected multiple rooms for edit using Tabular Room Data and those rooms are using differing thermal templates, Heating Setpoints and Cooling Setpoints, then the modifications are now applied in the correct way. page 3

4 <VE> ApacheSim ApacheSim error prevented when cooling tower is running at full capacity and the tower entering water temperature approaches its lower limit [ID ]: When the cooling tower cannot meet its imposed load but can still provide some cooling (cooling tower is under-capacity) and when tower entering water temperature approaches its lower limit, it can come too close to the lower limit. This led to an Apache error that has now been resolved so that simulations can be completed. ApacheHVAC Boiler Loads corrected for sequenced heating equipment on Hot Water Loop [ID ]: The boiler loads displayed in Vista and used to determine boiler energy consumption are correctly calculated when multiple heat sources are sequenced on a Hot Water Loop. This affects only models built in and DX Cooling coils now sized properly for systems in which the load on a single DX coil exceeds 100 kw: The autosizing now uses an effectively unlimited capacity during the sizing run so as to prevent inappropriate constraint the DX Cooling coil size for heavily loaded systems. Prototype Systems 5 and 7 corrected when no Demand Controlled Ventilation is applied [ID ]: MC11 controller stage 1 of the two-stage Demand-Controlled Ventilation (DCV) used in System configurations 05 and 07 is now set to zero when DCV is disabled via the System Parameters dialog (global setting) or at the zone level in the Loads Data spreadsheet. For variants of system types 05 and 07 that include the MC11 controller (prototype system 05b IDDE-DCV, or any 05 or 07 system to which the user has added MC11), the autosizing routine will now apply CO-2 driven modulation of the VAV box flow rate only to the layers/zones for DCV is included. Autosizing for 2-stage electric reheat coils in Prototype System 6 & 8 is improved [ID ]: The autosizing calculation in the Loads Data spreadsheet now sets controller MC7 leaving DBT = controller MC8 DBT 20 F. De-rating the leaving temperature of the first coil to 20 F (default; can be adjusted by the user) below the user-specified reheat LAT, which is applied without adjustment to the second coil, provides two-stage operation mimic actual equipment in terms of thermal comfort and improved operational stability relative to a single on/off electric resistance coil. Vista Right click Copy option available in IES report viewer [ID ]: When viewing a report in the IES Report viewer it is possible to select a portion of the report and right click to Copy it. ASHRAE 90.1 App. G - PRM PRM Report uses correct.aps file [ID ]: Multiple PRM simulations can be completed and saved using different file names. When the generate report action is clicked a dialog will ask which set of results you wish to generate the report for. The results will then be extracted from the correct.aps file. PRM report now reports CHP heat output correctly [ID ]: In the BPRM report the Combined Heat and Power Rated Capacity now reports heat output rather than the fraction of rated heat output. VE Compliance SBEM v4.1.c update 02 [ID ]: The latest version of SBEM version 4.1.c.4 is included in VE Compliance. Further details of this update are available from the BRE NCM website page 4

5 <VE> Room Group selection improvements [ID ]: Selection of Room Groups through the room browser is now significantly faster when in VE Compliance. Improvements made when removing an Apache System [ID ]: A warning is displayed when attempt to delete an Apache System if it is still assigned in either a room or a thermal template. Auxiliary Energy Equation 10 modified [ID ]: In light of an update from the NCM Modelling Guide the Auxiliary Energy Equation 10 is modified. Previously it was calculated as FPS3 = (0.2 * SCR) * SFPcentral this is now FPS3 = max((0.2 * SCR), FARmax) * SFPcentral Demand Controlled Ventilation can be applied when system NCM Type is Central Heating using Air Distribution [ID ]: The Mechanical Demand Controlled Ventilation options are available on the System tab of Room Data when the system serving the room is Central Heating using Air Distribution. Demand Control Ventilation options available for Air Conditioned systems [ID ]: When a room is served by one of the NCM System types with Air Conditioning (and the Mechanical Supply checkbox is hidden) the Demand Control Ventilation options "Demand Control based on Occupancy density" and "Demand control based on gas sensors" are available on the System tab of Room Data. Note: to apply DCV via Edit Group Attributes the Mechanical Supply checkbox must also be ticked on the Edit Group dialog to display these options. Mechanical Supply checkbox state retained when change between VE Compliance and Apache [ID ]: When the system assigned to a room is of NCM type Fan Coil Systems or Indoor Packaged Cabinet (VAV) the Mechanical Supply checkbox on the System tab of Room Data will remain ticked if change from VE Compliance to Apache and back. ApacheSim methods Air Permeability retained when change Regulations [ID ]: The Air Permeability value set on the Building Details tab of Building and System Data (ApacheSim methods) is retained when change Regulations. Criterion 3 report accounts for reporting interval [ID ]: In the Criterion 3 report the Solar Gain Limit now takes account of the reporting interval. Criterion 3 Solar Gain variables added to 'Export Room Data' file [ID ]: The Criterion 3 Solar Gain Total and Criterion 3 Solar Gain Benchmark values are added to the exported room data. Section 6 ApacheSim BRUKL for Portable Modular Building displays correct U-value limits [ID ]: A Section BRUKL generated by ApacheSim for a building defined as Portable/Modular, Planned Time of Use More than 2 Years and Date of Manufacture After 1 October displays the correct limiting U-values in Section 2 of the BRUKL. SBEM Door construction assignment improvements [ID ]: When the door type is set as "Curtain wall" or "Wall or roof element" then the LENGTH keyword is written out to the.inp file. BRUKL displays correct u-values when project contains conflicting Construction IDs [ID & ]: When a project contains multiple Constructions in the constructions database with the same ID ApacheSim method BRUKL reports will display the correct u-values for all elements in the Criterion 2 table and the failing Constructions warning will only be displayed where applicable. Radiance Illuminance - Working Plane calculation crash prevented [ID ]: A crash is prevented when trying to abort an Illuminance - Working Plane calculation while the simulation progress bar shows "pre-sim complete". page 5

6 <VE> Navigator for BREEAM BREEAM Day lighting HEA 1 Report clarifications [ID ]: The Daylighting HEA 1 Report has been amended to clarify the displayed results. Column headers in the Simulated daylight table now refer to AOI to represent the result is not for the entire space and target DF reflects that the benchmark criteria to be met for different credits can vary. DF and AOI (Area of Interest) corrected for Retail and Education (tertiary). Rainwater/greywater consumption capped at the max toilet water usage [ID ]: Rainwater and greywater can only be applied to toilet & urinal water consumption. Rainwater/greywater consumption is capped at the max toilet water usage. Note that if rainwater and greywater are both enabled, then greywater shall have priority, with 100% greywater allocated to flushing. The remainder is then serviced by rainwater. This is reflected in the greywater/rainwater consumption figures (where greywater usage 100% of generated and rainwater may be less than 100%). BREEAM Navigator HEA 8 changes [ID & ]: The following prompts are added to the Navigator for BREEAM and they are a prerequisite to generating the Indoor Air Quality HEA8 report: Intakes / exhausts are > 10m apart Intakes / exhausts are > 20m from pollution Windows are > 20m from pollution When these criteria are met a credit is awarded (even in the scenario where no rooms are included in the analysis). BREEAM Indoor Air Quality HEA 8 [ID ]: The Indoor Air Quality HEA 8 calculation has been corrected so that the Target Fresh Air Rate for Education 5 l/s (1350 PPM CO2) is used and report is updated to reflect this. HEA 8 calculation change [ID ]: Indoor Air Quality thresholds now adjusted to reflected metabolic rates. BREEAM HEA10 report improvements [ID ]: The temperature assessment table shows "-" for air-conditioned rooms in the "Tests: Winter" and "Tests: Summer" columns. The PMV assessment table shows "-" for naturally and mechanically ventilated rooms in the "Tests: PMV +/- 0.5" column. Also, when no spaces are selected then no credit is awarded. page 6

7 <VE> <VE> Changes General Room query button improvements [ID ]: The Room Query button is enabled when initially switching into a supported module with a single room selected or when selecting a room group from the browser that contains a single room. VE-Gaia Climate Energy Index "9-5 hours of use" results reported correctly [ID ]: The Climate Energy Index report is corrected so that the value reported for "9-5 hours use" is correctly calculated taking into account only the energy use between the hours 9-5. LEED USA Day Lighting Credit threshold changed to 10fc [ID ]: The LEED USA Navigator and Toolkit are updated so that Day Lighting EQ8.1 is assessed against a threshold of 10fc (108 Lux) when Rating system is version 3. The LEED Day Lighting report is corrected to show 21 September as Simulation date (previously displayed the date the report was generated). ModelIT Connect spaces improvements [ID ]: Connect Spaces is now correctly exited if you move down a level (e.g. by double-clicking a room) or if you switch tools. Apache Profiles Database ApPro is improved to avoid multiple copies of profile with same ID [ID ]: When project contains multiple.pdb or.pro files these are not merged into Profiles Database so project does not contain multiple duplicate profiles. Apache View Room ID is unchanged when edit Room Name in Room Data [ID ]: When a Room Name is edited on the General tab of Room Data the Room ID is unchanged. Tabular Room Data import improvements [ID ]: Templates are now recognised on import if the name has leading/trailing spaces. "From Template" option added to Air Exchange "Temperature Profile" dropdown [ID ]: "From Template" option has been added to the dropdown for Air Exchange "Temperature Profile" column in Tabular Room Data. This will be the first item in the drop-list and when "From Template" is active, the cell text will be shown in the "From Template" colour (blue by default). SunCast shading file validation improved [ID ]: The validation check on the Suncast shading file is improved so that the erroneous error Building shading file is out of date is not displayed when the shading file has been calculated on the latest version of the building geometry. There may still be occasions where this error occurs after the shading file has been re-calculated for latest geometry, this is usually due to errors in the geometry. IES is working on a full robust solution for this but in the meantime users are advised to check geometry in ModelIT (Settings menu >> ModelIT, tick Intersections, Zones and Surfaces then click the Check button) and correct any errors before re-running the SunCast calculation. page 7

8 <VE> ApacheHVAC Loads data spreadsheet updated to include SAT resets for systems 6, 8 and 9 [ID ]: The Loads Data spreadsheet is updated so that for systems 6, 8 and 9 the MC1 and MC2 control Dry-bulb Temp at min signal includes Cooling Coil SAT reset as defined via the System Parameters action.

Time Switch dialog retains changes when closed by Enter key [ID ]: Edits made on the Time Switch dialog are retained when user exits dialog via Ok button or using Enter key on keyboard. Default values for Slope and Orientation in Room Unit controllers updated [ID ]: The default values updated as follows for each occurrence (regardless of association with the On/Off setpoint control, Proportional Flow control, or Proportional Temperature control): Orientation: 180 degrees (south) Slope: 45 degrees (typical for mid-latitude locations on northern continents) Default values for all three heat pumps AAHP, ASHP, and AWHP updated [ID ]: For the three heat pumps, Air to Air Heat Pump, Air Source Heat Pump and Air to Water Heat Pump: Changed the default value for Min Source Temp to -10 C (14 F) and Source Temp to C (47 F). For ASHP and AWHP the default value for Output has been changed to 132 kw ( kbtu/h). No error when import EWC Chiller [ID ]: When an EWC Chiller is imported without first defining a Condenser Water loop then a Condenser Water Loop is automatically added to the Chilled Water Loop rather than display an error and block the import of the chiller. Shading surfaces removed from Rooms dropdowns [ID , & ]: The select Rooms dropdowns in Create/Edit Multiplex, Assign Room ID s and the HVAC Wizard list only rooms present in the model and do not display Shading surfaces (or blank entries). Vista/VistaPro Tariff Analysis improved to work with multi-language OS [ID ]: When running on a non-english machine Tariff Analysis operates in UK regional mode so the full stop is used to denote a decimal separator. PRM Custom Room Group names can be created using the reserved names "SPACE:" and "BLDG:" [ID ]: Custom Room Group names can be created using the reserved names "SPACE:" and "BLDG:" in the Prototype 90.1 Grouping Schemes. The identifier "(custom)" will be added to the new Room Group. Baseline model not lost when close VE while editing Baseline building [ID ]: If the VE is shut down while making edits to the Baseline building model, when the project is opened again the Baseline model still exists and can be selected for further editing or analysis.

9 <VE> PRM Proposed and Baseline models updated when make edits [ID ]: Improvements are made so that Proposed and Baseline models are updated appropriately when edits are made to the project and these changes are reflected in subsequent simulation results without requirement to regenerate the models. In particular; 1. Edits made to Thermal Templates in Building Template Manager will filter through to assigned rooms in the Proposed and Baseline models (all variants) 2. Edits made to the Proposed model in Room Data or Edit Group Attributes (ASHRAE 90.1 App. G - PRM application) are applied only to the Proposed building. 3. Edits made to the Baseline model in Room Data or Edit Group Attributes (ASHRAE 90.1 App. G - PRM application) are applied to the Baseline building (and all variants). Note: in the case where any changes are not reflected in the Proposed or Baseline models, these can be refreshed by running the Room Loads Calculation from the Sizing Runs section of the Navigator. VE Compliance Efficiency improved when editing large projects [ID ]: When editing large projects using Room Data the VE refresh time is improved after changes are applied. BER & TER adjustment factors now incorporated in Vista results [ID ]: NCM guidance allows for downward adjustment to the BER and TER for electric power factor and (except in Scotland) a factor for lighting monitoring. These adjustments were previously applied to the BER and TER values in a post-processing step after simulation. They are now applied during simulation, and are therefore evident in Vista energy and CO 2 results and in breakdowns presented on the BRUKL document Technical Data Sheet (Energy Consumption by End Use and Energy & CO 2 Emissions Summary tables). ApacheSim BRUKL Energy & CO2 Emissions Summary section corrected [ID ]: A BRUKL report generated using the ApacheSim method reports the correct Heating + Cooling Demand (MJ/m 2 ) for the whole building.

Auxiliary energy calculated correctly for Central Heating using Air Distribution system [ID ]: When NCM System type Central Heating using Air Distribution is selected from NCM System Wizard the Auxiliary Energy is calculated correctly for Actual and Notional Building taking into account peak heating load (but ignoring peak cooling load). When Actual Building uses this system type the corresponding Notional room has a room level Mechanical Supply ticked and the terminal SFP set to 0.5 W/(l/s). Heat Recovery applied when NCM System type is "Central Heating using Air Distribution" [ID ]: When the NCM System type is "Central Heating using Air Distribution" any Heat Recovery defined in the Ventilation tab of the NCM System Wizard will be used during the simulation. EPCgen.net activation code retained when enter VE Compliance [ID ]: The Previously entered Part L2 Assessor Number and EPCgen.net activation code are retained in Building and System Data when user enters VE Compliance. page 9

10 <VE> Modification to treatment of "Clause nat vent BER reduction factor [ID & ]: The parameter 'Clause nat vent BER reduction factor' applicable to Scottish NCM analyses is now applied only to the space heating and auxiliary energy components of BER, and is thus more directly related to the factor referred to in Clause The text label for this parameter has been changed to emphasize that it applies only to energy consumption for natural ventilation systems. Its default value has been changed to zero and it is now displayed to 4 decimal places. FlucsDL/Pro FluscDL/Pro improved when room names are changed after FluscDL/Pro simulation [ID ]: If after a FlucsDL/Pro calculation has been performed the user then edits room names, on returning to Flucs a message is displayed to give the user the option to retain or discard the results associated with each room ID. page 10

Loads Data spreadsheet "Zone cooling coil leaving air temp" revised [ID ]: The Loads Data system 9 "Zone cooling coil leaving air temp" value is edit to be 55F so that the Room Cooling Loads tab "Supply Air DBT" can accept input of 55F for sizing other systems. Note: this minor issue caused slight oversizing of autosized systems and only affected VE versions Maximum Occupancy for 62.1 Ventilation revised [ID ]: The Maximum Occupancy value written to the Loads Data spreadsheet "Loads Results data" tab, which previously excluded Diversity Factor, now also excludes influence from any Occupancy schedule or profile---i.e., when the maximum value in the profile is less than 1.0, this will not reduce the peak occupancy for ventilation rates. The note in this section of the Loads Data spreadsheet has also been clarified accordingly, to read: "Maximum Occupancy. From Room Data excluding both Diversity Factor and any influence from Occupancy Profiles. A diversity factor or schedule profile that never reaches 1.0 or 100% occupancy will not reduce the peak value for sizing of ventilation rates. The occupancy profile will, however, influence the dynamic determination of Design Cooling Load via ASHREA Loads, and thus system sizing." MacroFlo Opening Types dialog input validation improved [ID ]: Crack Length only accepts values in the range 0 500%. [ID ]: Crackflow coefficient shows correct tooltip when units are US-IP. [ID ]: Louvre Coefficient of discharge only accepts values within the range Cd.
