What’s new in 2.28/2.29?

Microsoft have had the facility to add custom buttons on a ribbon (toolbar) in Excel for some time. Tim Martel and the AECB have teamed up to create one for PHPP which speeds up common tasks and extends what PHPP can do. No special PHPP is needed. PHribbon v2 is now released with the February update of Full LCA Cradle to Grave Embodied CO2:

  Features Beginners might like  Features Advanced PHPP users might like
Climate easier selection of climate region using a more detailed map map shows what counties are in what region, the address of the site defines the region
U-values library of typical constructions to start from library of typical constructions that you can copy from previous projects and edit
Lambda values list of lambda values lambda 90/90 vales & link to BBA certificates useful for certification
Orientation tool very simple way of entering bearings of each wall Draws outline of building as a crosscheck (if you have entered wall lengths)
Wall Shading quick to enter, this part of PHPP easily missed gives absorbtivity and emissivity of a range of common materials
Window tool enters different window styles quickly
calculates the d-reveal, and enters the other info
shading info entered as formulas, allows window dims to be changed, also calculates the d-reveal for a long row of any number of windows
CheckPHPP runs through a standard check for PHPP and gives you a list of what is OK and what needs attention  you can customise the checks you do, add your own checks, remove them or just temporarily ignore some
Summarise PHPPs List results for recent PHPPs you have done useful to summarise a large development where you have many individual PHPPs for different blocks.

Build PHPP

Climate Select the climate region using county boundaries
U-values Enter U-value assemblies and refine with λ-values. Both with editable libraries and links to BBAs.
Areas Enter the orientation of walls, draws the outline of your building to check your wall entries (if you’ve included wall lengths), second tab with further wall info.
Window Tool Enters the dimensions, ‘1’s and ‘0’s, and enters dreveal and shading
Ventilation Enters the sheltering info from a menu
Protect Sheets Protects all the heat loss sheets, use if you unprotected them while editing
Check PHPP Takes you to cells with common items to check, keeps a record of your response, customisable

Window Tool

The window tool helps you add windows by entering much of the data for you. On the windows tab it enters the dimensions, ‘1’s and ‘0’s and name and quantity. On the Shading tab it enters the d reveal, o reveal, d over and o over. It uses frame dimensions from the components tab to enter the d reveal as a formula so it will update if you change the window or frame dimensions.

A new option (left) allows you to enter a long row of any number of windows and calculates the D reveal. Initially all the windows will be the same but you can change the widths later and the D reveal will still be accurate.

Daylight Factor

This exports window information to a daylight factor spreadsheet by Mark Siddall of LEAP. It helps you plan window sizes which give enough daylight without over-provision. Good windows have 5x the heat loss of a good wall so it is important not to over size them.

Embodied CO2

The PHPP already has quantities of 75% of the materials of the building, this button makes it relatively straightforward to obtain lifetime CO2 using an extensive list of hundreds of EPDs. The calculation is for the full lifetime Embodied CO2 suitable for design stage estimates of RIBA 2030 challenge (though an official RICS calculation requires more). Read more 

  • US Imperial Units version – a version that can be used with PHPP 9.7IP is being tested
  • PHribbon in different languages – PHribbon can now work on French, German and Spanish PHPPs automatically, more languages available on request. It’s already possible to show the ribbon itself in different languages and in time the dialogues will also be translated.
  • Compatibility – all tools are compatible with  earlier versions of PHPP: 9.3, 9.1 and 8.5 as well as 9.6. Copy constructions from older projects, estimate retrofit costs or Embodied CO2
  • Retrofit Costing – links to rates of master PHribbon list, allowing you to update results automatically if you change the rates in the master list. Read more
  • Certifier Export – a new button creates the summary certifiers need to send to the Passivhaus Institute
