The Latest PHPP is Revolutionary

PHPP_screenshotPassive House Software Is Leaping Forward

With each iteration of the PHPP (Passive House Planning Package), Passive House practitioners get more powerful tools to reduce building energy by design. Of particular importance to the US audience, the version of PHPP 9 in Imperial Units (PHPP 9 IP) has been released, which is the first energy modeling software for the non-metric world to combine low-energy design with renewable energy supply to create cost effective solutions.

From The Back Of A Napkin, To A Premier Planning Tool

If you’re the type that enjoys numbers, you’ve done this: started a major project by opening up a blank Excel sheet and playing with some numbers to get a sense for your limits. Then you go from there, adding complexity and detail until you get the refinement you need and feel comfortable with and answer that reflects reality.

We say “software” when referring to PHPP, but as you may know, it’s an Excel spreadsheet. Since its development in 1998, it has been continuously tested and re-created to account for conditions around the globe, in every climate. The first editions looked primarily at space heating balances and for heat distribution and supply, as well as for the electricity and primary energy demand. As versions advanced we saw the addition and deepening integration of windows, shading, heating load and summer behavior, cooling and dehumidification demand, ventilation for large objects and non-residential buildings, taking into account of renewable energy sources, and retrofitting of existing buildings. The PHPP is continually being validated and extended on the basis of measured values and new research findings.

Ongoing PHI scientific research measures results and compares them with the calculated results. The result is a high correlation demonstrated between the PHPP demand calculations and the scientific monitoring of projects. With careful planning of building efficiency, there will be no performance gaps.

In the building world, transitioning to a post-carbon world means optimally integrating renewable energy supply with building construction, retrofitting existing building stock, and smartly dealing with demands of cooling and dehumidification in all climates. It is an ambitious comprehensive vision of how buildings should be made, and PHPP 9 was developed to deliver on it.

What makes it revolutionary? Three primary things:

  1. Variants: Variants provide greater cost and optimization control for new and retrofit construction. PHPP 9 enables input of efficiency parameters for different variants for easy comparison. Different steps of a renovation can also be entered, making it possible to depict the improvement in efficiency resulting from each individual refurbishment step and to conveniently assess projects with a long-term strategy.
  2. Positioning for Post-Carbon Primary Energy: Buildings planned today will be supplied with renewable energy to an increasing extent throughout their service life. This fact has been accounted for in the PHPP 9 through a new building assessment based on a new system for renewable primary energy (PER / Primary Energy Renewable) and allows for buildings executed today to be optimized to the power supply of tomorrow.
  3. Climate-Dependent Retrofits and Cooling: The international EnerPHit criteria embedded in PHPP 9 make it possible to specify minimum quality standards for the relevant building components in a renovation project depending on the location. In addition, the cooling and dehumidification demand requirements can be determined depending on the use-related internal loads and the local climate conditions.

Connection to designPH: The PHPP IP 9-patch is complete and being tested for release. The patch will allow IP users to export from designPH 1.1 to PHPP 9 IP, a vital connection for those using the Sketch Up-based design tools.

Get Up-To-Speed At NAPHN16

To be the first to see these new advances, you need to be at the NAPHN16 Conference and Expo, June 13 & 14, where PHPP 9 will be featured in the following workshops and conference sessions:

Coulda, Woulda, Shoulda: Variant and Optimization of PHPP
Workshop, Saturday, June 11th, 9am – 12:30pm Attendees will learn how to use the new Variants tab in PHPP v.9, plus take a look at an alternate software service for PHPP optimization that offers simple, graphic outputs. Learn how to quickly identify key components and opportunities for improving your designs, or communicating options to clients.

PHPP v.9: What’s New, with a Focus on Retrofits
Workshop, Saturday, June 11th, 1:30 – 5pm This class will review all new aspects of the latest changes and new developments in the PHPP using the newest v.9 release (IP and SI versions). You will learn to work with PHPP’s numerous features with a focus for application to the building stock – before, as well as after energy retrofit – including the comparison of different design options and the development of a step-by-step retrofit plan.

Passive Software Tools SketchUp and PHPP9: Think in 3D, Calculate Payback and Optimize for the Renewable Future
Conference Session, Monday, June 13th, 11:30am – 12:30pm Today designPH and PHPP version 9 are critical tools essential to delivering on the predictability and performance of Passive House. Learn how to leverage the power of integrated 3D design through the designPH plug-in. And learn how PHPP9 can empower you to smartly integrate renewables and make cost effective building construction choices.
