14 February 2012: Version 5.03a1 Build 006 - main changes

1. SAP 9.90:
   Draft SAP 9.92 (SAP 2012) module available.

   New function to convert a SAP 9.90 to SAP 9.81, giving backward compatibility.
2. U-values:
   Introduces calculation templates which enables users to build up their own library of commonly used calculations and to use calculations prepared by construction product manufacturers.
   Suspended beam and block ground floor calculations no longer has option for non-calculated deck resistance.
3. Payback module:
   PV calculation corrected to only use SAP 2009.

10 February 2012: Version 5.03a1 Builds 004 & 005

1. Internal development builds and not public releases.

31 January 2012: Version 5.03a1 Build 003 - main changes

1. SAP 9.90:
   Now reports cylinder size in checklist if heat pump PCDF values are over-ridden.
   New function to convert a SAP 9.90 to SAP 9.81, giving backward compatibility.
2. U-values:
   Region setting to Middle East now gives U-value rather than R-value result.
   Air space resistance calculator added. Addresses unvented air layers and voids, well-ventilated air layers and slightly ventilated air layers.
   New function in File menu: import U-value calculation from another project. Makes it easier to re-use standard calculations.
   Tapered insulation: now possible to override base thickness and lambda value for individual sectors.

05 January 2012: Version 5.03a1 Build 002 - main changes

1. SAP 9.90:
   Improved import of mechanical ventilation parameters from SAP 9.81 to 9.90.
   File location removed from bottom of Scottish EPC. Now possible to enter a second main heating system with heating fraction of zero, which can then be assigned to water heating.
   Resolved occasional problem with EPC lodgement issue at draft approval stage.
2. <VE> Import to SAP:
   Import now works from <VE> 6.4 and goes directly to a SAP 9.90 calculation.
   New option to copy non-geometry data to all SAP 9.90 dwellings in project.
3. U-value:
   Modification to cut-to-falls insulation layers to allow different base thicknesses of insulation.
   R-value calculation for Australian regulations now included, with different values for heat flow inside to outside and outside to inside.
   New option for variable layer calculations which enables the calculation to be converted to a standard calculation with a selected layer from the variable layer pane replacing the variable layer.
   Well-ventilated cavity calculation to ISO 6946:2007 now included.
   Resistance of unheated spaces ISO 6946:2007 method now added to Edit Construction dialogue.
   DeltaUf correction now uses total unbridged resistance.
4. Condensation risk analysis:
   Climate data for Republic of Ireland added.
5. Psi-value:
   Alpha development version of a psi-value assistant for use with THERM added to software.

13 October 2011: Version 5.03a1 Build 001

30 September 2011: Version 5.02a1 Build 016 - main changes

1. Payback calculator:
   JPA Designer now includes a payback calculator for PV and wind turbines.
   This new module is currently free for registered users of the SAP modules.
2. U-values:
   Limit on number of bridged layers increased from 5 to 9 to allow calculation of multi-foils and other complex constructions.
   Variable layer calculations now work correctly when an air gap correction is applied to the variable layer.
3. SAP 9.90:
   Code for Sustainable Homes report now available as an output, showing values for Ene1, Ene2 and Ene7 Zero carbon assessment now included.
   Compliance report no longer applies the in-use factor to the SFP when testing efficiency.
   Resolved occasional overprinting when large numbers of openings included.
4. SAP 9.81:
   Now possible to select 'as-built' for a dwelling with an assumed air permeability of 15 to produce an 'as-built' regulations checkist.
   Corrected an issue where 9.81 calculations picked up the 9.90 fabric U-value after a 9.90 calculation had been opened.

09 September 2011: Version 5.02a1 Build 015 - main changes

1. Overprinting problem fixed.
2. Now includes a zero carbon home print out.
3. Allows EPC's for Scotland to be printed out from JPA Designer.

30 August 2011: Version 5.02a1 Build 014 - main changes

1. “Error finding SAP Version 9.9 dwelling” fixed.

12 August 2011: Version 5.02a1 Build 013 - main changes

1. Postcode location conflict between North West England and South West Scotland fixed.

03 August 2011: Version 5.02a1 Build 011 - main changes

1. Error message when lodging a V15 EPC from a SAP 9.81 calculation now correctly warns that it is not a SAP 9.90 calculation.
2. Program no longer retains Product Characteristics Database settings when the primary heating is switched from a boiler to a heat pump with default efficiency.
3. Now possible to specify the flue arrangement for boilers in the Product Characteristics Database which can have either open or room-sealed flues.
4. Incorrect fail report on some mechanical ventilation systems resolved.

12 July 2011: Version 5.02a1 Build 010 - main changes

1. Prevents EPC showing dollar sign instead of pound sign on 64 bit Windows 7 systems.

23 June 2011: Version 5.02a1 Build 009 - main changes

1. It is now possible to set a ground floor as a party floor in the Dimensions tab. This allows the correct specification of ground floor flats or maisonettes with basement flats below.
2. The compliance checklist now shows the dedicated solar volume instead of the effective solar volume.
3. The compliance test for the efficiency of microCHP now uses HPER as a maximum rather than a minimum.

1. Resolved EPC lodgement issue with heating controls on community heating schemes.
2. TER calculations in Scotland now use thermal mass parameter of proposed building.
3. TER calculations for biomass heating systems in Scotland corrected to use package 5.
4. Compliance check for microCHP systems now uses HPER figure rather than SEDBUK rating.

1. Amended reference on regulations checklist to on-peak electricity to off-peak.
2. Northern Ireland EPC lodgement resolved.

1. Heat exchangers for community heating systems: the compliance check on insulation thickness has been removed, and thicknesses below 50 mm will no longer report a fail.
2. Party wall U-values over 0.20 W/m2K will be correctly marked as a fail.
3. Main SAP window will now only shows the values for those opaque elements which are present in the calculation: the listing now includes party walls.

1. Resolved access violation error as a record is being added to the database while issuing an EPC for a dwelling with user-entered boiler efficiency.
2. Resolved error with boilers with integral flue gas heat recovery.
3. Resolved BRE lodgement issue with flats.

1. Fixes issue with EPC lodgements through BRE.
2. No longer allows switching between using gross and net areas once any building element data has been entered.
3. Average room height now relabelled average storey height (avoids confusion as includes floor depth).
4. Data accuracy now limited to two decimal places (BRE requirement).
5. Water heating system no longer has any efficiency improvement for weather or enhanced load compensator.
6. Items on the SAP 9.90 edit menu now go to the correct tabs following the re-ordering of the Ventilation tab.
7. Occasional overprinting on final pages of SAP 2009 output corrected.
