PHPP 8 (2013) Now Available: many improvements (hot/humid climate, workflow, PV-calcs etc)

PHPP8The 2013 version of the Passive House Planning Package is now available at 475: PHPP 8.  By incorporating recent research results by the Passive House Institute on high performance buildings in challenging climates around the world, PHPP 8 includes validated algorithms that ensure its suitability for all climates, including those with cooling and dehumidification requirements.  Purchase it here.

Comparative studies with dynamic building simulations have shown that the algorithms in PHPP 8 deliver reliable results for cold, warm-temperate, hot-humid climates. “With its latest features, the PHPP 8 keeps pace with new developments in the field as well as the increasing global distribution of energy-efficient building,” remarks Dr. Wolfgang Feist, founder and director of the Passive House Institute in Darmstadt, Germany. The improvements include the tabs and outputs for:

PHPP8 dehumidication calculation 475

  1. Peak cooling load calculations with dehumidification, including sensible cooling load fraction (Cooling load tab, see image above)
  2. New tab with all Certified Passive House Components (windows, mechanicals etc)
  3. Geothermal and mini split heat pumps (HP and HP ground tab)
  4. Electricity production from photovoltaic systems (PV tab, see image below)
  5. Conversion sheet and IP/SI macro (Mac requirements: Excel:mac 2011 and OS X V 10.6.8)

PHPP 8 additionally features improved tab layouts, which facilitates data entry for quicker input and review of projects.

Coming Soon:  designPH (sketchup plugin)

The designPH plugin, available in 2014, will further optimize creative planning with a Trimble SketchUp-based tool allowing users to model their Passive House projects in 3D. It will simplify the process of entering data into PHPP but also provide preliminary feedback on the performance of a design. designPH

Coming Soon:  Local tab for code compliance/incentives

The PHPP With its detailed manual has long provided a reliable basis for the design of energy-efficient buildings. In many countries it is also accepted as proof of compliance with the Passive House criteria for subsidies and low-interest loans. To facilitate this in the USA, we are working on a local Tab in which local code compliance/incentives can be calculated with the PHPP8. Please contact us if you are interested in working with PHI and us on a tab for your specific jurisdiction.

Transparent calculations

As with all PHPP versions, the Excel-based software tool is an open tool in which all calculations/formulas are visible – not a black box like most energy modelling software. Making the performance of the building/design, clear, transparent and understandable for professionals wishing to gain special insight to its workings. Giving architects, designers and energy consultants the world the tool to optimize their designs and components systematically and on the basis of hard figures.

The PHPP 8 also places a greater focus on the increasingly popular combination of Passive House and renewables In addition to the solar-powered hot water generation already covered by previous versions, the PHPP 8 allows for the calculation of energy outputs from photovoltaic systems, heat pumps and geothermal probes. A procedure for estimating the solar heating supply has also been integrated into this new version.  Buy it here.

    does the IP/SI macro mean we will be able to enter IP units like on the version I got through PHIUS some years ago?

      Hi Tom,
      Yes and no. Each time you click a cell to enter a quantity a window pops up – allowing you to enter quantities in IP, which then converts it to SI and populates the cell in SI. By clicking on the SI cell entries the window will show you the IP value. It is easy and intuitive and allows all the formulas to be readily viewable. The macro that does the IP/SI dance can be turned off and on – depending if the user needs it. We’ll put some screen shots up in the blog post to illustrate this shortly.
      Best,
      Ken

        Great, thanks Ken. Any idea when the Sketchup plugin is coming?

          Wish I could say better, but I’m taking their statement of later this year to mean December 31st. Hopefully sooner. Sorry I can’t be more precise.
