VE 2017 Feature Pack 04 Changes

Navigator for ASHRAE 90.1 PRM

Energy results reported correctly for legacy models [ID-22309]: If you upgrade a pre VE 2017 model
that contains simulation results then these results do not contain Meter data. When generating the
PRM report the energy results will now be reported correctly. This fix is extended to cover cases
where Prototype data was imported via the 90.1 2004 Navigator.

VE Compliance

SBEM v5.4.a integrated [ID-]: SBEM v5.4.a is integrated inline with NCM Modelling Guide 20
November 2017 revision.
BRE Release notes state that in addition to the changes specified in the updated NCM Modelling
Guide SBEM also includes two improvements

-   calculation of Lighting Energy which now follows the NCM Activity Database specified lighting
    hours and not occupied hours as was previously used.

-   calculation of peak space cooling value used in fan power density calculation (for auxiliary
    energy determination) includes heat gains from Display Lighting which were previously
    excluded.

Notional Building District Heating factor amendment [ID-]: Minimum threshold for District Heating
CO2 Factor to be applied to Notional Building is increased (Previously min threshold was 0.15
kgCO2/kWh, this is now 0.19 kgCO2/kWh).
Primary Energy Factor is changed in line to be min 0.85 kWh/kWh.

Inference Method LED Lighting modification [ID-]: The inference data for LED lights is changed for
buildings (other than those classed as portable modular), the Luminaire lumens per circuit Watt is
changed from 27.5 (side-lit and 33 (top-lit) to 50 (for both side-lit and top-lit spaces).
Auxiliary Energy calculation includes Fan Energy for Heating Systems [ID-]: Heating systems with
integral fans are defined as Central heating using water (convectors) and Other local room heater.
An additional fan energy is now added to auxiliary energy for these systems, this is specified by the
user as an additional Fan Power (defined as W/kW heat output by the heating system).

This additional energy consumption is added on to total Auxiliary Energy for the zones served by
these systems.

BRUKL SFP Limit for Active Chilled Beams modified [ID-]: When NCM System type is Active Chilled
Beams and Air supply mechanism is "Centralised balanced A/C or Mech Vent system" a new code is
written out for the BRUKL document which means the system SFPs table will compare against a
target 1.9 W/l/s

Setpoints frame on the Zone Temperature, Humidity & Equipment tab, the dehumidification option
has been enabled and set to ‘System supply air conditioned per zone RH sensors’ by default when a
controller with the 'Cooling coil - DOAS dehum' link is present in the system. This will then enable
the Zone RH high limit system parameter.

Navigator for ASHRAE 90.1 PRM

Crash prevented when accessing system parameters of baseline systems [ID-9205]: A crash has

Error failed to read illum file due to inactive spaces prevented [ID-13329]: A ‘Failed to read illum
file’ error has been prevented when running a PRM simulation linked to Radiance. This was caused
by the sensor calculation producing an invalid illuminance file due to inactive spaces in the model.

Improvements made to Tabular Edit framework to prevent a crash when trying to assign spaces in
90.1 PRM Navigator workflow without importing prototype data.

PRM Report Energy Cost value has been corrected [ID-16218]: Energy costs reported will match
units and tariffs applied in.

Error prevented when importing prototype template data [ID-16257]: Improvements made when

Navigator workflow so that values entered in unmet load hours settings dialog are now saved
properly when running in IP units.

Elevator annual energy consumption translates properly to BPRM Report [ID-16573]: Fixed an error
where elevator's annual energy consumption was not translating into the BPRM report properly.
Correction of Legacy Simulation mode [ID-17943]: Correction made to legacy simulation mode so
that simulations now only run for the selected baseline models.

Unit labels are now correct for IP and Metric in Thermal Comfort Report [ID-18410]: A fix has been
implemented to rename the labels in the report to reflect the unit choice of the model (IP and
Metric).

An error has been prevented when upgrading models [ID-18765]: An error has been prevented
when upgrading models from earlier versions of the VE. This was causing gains for lighting and
receptacle equipment to be excluded from reports.

Parallel Simulation Manager

Files now downloaded properly and error prevented when opening aps files [ID-15928] A fix has
been implemented to ensure that aps files are downloading correctly and not causing an error when
opening files.

Navigator Key Model Inputs Comparison report to generate has been fixed and is now functional
when clicked.

SBEM ‘VENT-STRATEGY’ keyword updated [ID-17848]: The SBEM keyword for PVS input has been
updated. Previously this was written out as ‘VENT-STRATEGY = Ventilated modules’ but now ‘VENT-
STRATEGY = Moderately Ventilated modules’ is written out to allow calculation in SBEM.

SBEM kW Peak PV inputs retained when upgrading projects [ID-19741]: A fix has been
implemented to ensure that PV values are now being retained when upgrading from VE 2016
projects.

VistaPro

        reference, do not treat it as NCM for the purpose of filtering.
       When an NCM gain or air exchange is copied, "NCM" is removed from the reference.
