All architects hoping to design to the Passive House standard need to know how to use The Passive House Planning Package (PHPP).
This book provides much needed supplementary guidance for purchasers of the PHPP establishing the standard within the UK context and is a concise, user-friendly, highly illustrated step by step companion for practitioners and students who want to use the PHPP as a design tool.
By improving their in-use understanding of the PHPP, this guide enables readers to fully comprehend their scheme in terms of the impact of orientation, envelope shape and ratio to floor area, fabric build-ups, fenestration ratio and shading effects on the energy balance – the essential criteria for all low energy buildings.
Fully supported and endorsed by The Passivhaus Institut, the book will act as an invaluable gateway for brand new as well as more experienced PHPP users.
From the foreword by Dr Wolfgang Feist, Passivhaus Institute (PHI)
"In this much needed visual guide, clear and easy to follow descriptions lend themselves to designers, guiding them through the necessary inputs and helping them understand what the outputs mean for their buildings. This book will help further the Passive House Standard and contribute to a better built environment."
Extract from the Introduction "What is PHPP?"
The PHPP is a vital design tool and not something to be feared. It is actually very easy to use once you get the hang of it and does not require advanced abilities in computer modelling. Complex dynamic models were used to create the PHPP, but the PHPP itself is a series of interlinked Excel spreadsheets in one workbook.
Therein lies one of the great advantages of the PHPP; the Excel workbook can be used by anyone with access to Excel or Open Office and basic Excel training, so architects can share the workbook with mechanical, electrical and energy consultants. The reliance on standardised software allows avenues for cross collaboration and encourages technical dialogues to develop. Data can also be easily and quickly extracted to provide useful graphs for clients or consultants.
The PHPP has been developed for designing Passive House buildings but is also a useful tool to design other low energy buildings, providing very accurate results.
Karl Parsons, Passivhaus Designer, WARM: Low Energy Building Practice
When first using PHPP I found it somewhat bewildering. This book is readable and accessible, without dumbing down the process. It is a welcome and useful overview, and is suitable both for people new to Passivhaus and those with some knowledge but who are not entirely confident using it.
Sofie Pelsmakers, environmental architect and author of The Environmental Design Pocketbook
A lovely book, which does exactly what it says in the title. No other publication matches its clarity and completeness, setting out key principles while also making what seems a complex tool accessible to designers and students.
Nick Grant, Technical Director, The Passivhaus Trust
This book promises to help designers get to grips with the basics of energy modelling, by using PHPP as a powerful and flexible interactive design tool. This deeper understanding can only result in better, more comfortable, energy efficient buildings.

PHPP is an excellent design tool which can be used to develop low energy building which work in practice. When understood, designers can quickly test different design solutions and options. However, for those who have not undertaken Passivhaus training or those with limited experience in its use, it is easy to make mistakes. The size and number of worksheet entries required to complete a model can also be daunting to start with. The original PHPP manual, which is translated from German, provides lots of useful information but is not the easiest read and does not include any worked examples.
This book methodically goes through the process of inputting data into each worksheet in a logical sequence. This is based on an example residential building in the UK. The book does not go into detail of non-domestic building design.
Screen shots of the worksheets show the inputs for the sample project and the values entered. Written descriptions explain how the cell inputs work. It is particularly useful to have this completed example based on a UK building to refer to. This gives the reader an understanding typical inputs which could be expected.
Throughout the book common mistakes are highlighted and their significance explained. Reading these alone could save the reader from making errors which are often not spotted until the design is assessed by a Passivhaus Certifier. Anyone reading this book should have a much better understanding of the Passivhaus design principals and how to use PHPP as a successful design tool.
A brief description of thermal bridges and how they should be used in PHPP is also given. Again, this includes useful default values.
This book provides a clear, easy to read guide and reference to PHPP. I highly recommend this book as a valuable reference to those experienced in using PHPP to dip into specific topics. At the same time it could equally be useful for those new to Passivhaus design to understand the basic inputs required for each element of the construction.

The following extract is taken from Elrond Burrells review of PHPP Illustrated: A Designers Companion to the Passive House Planning Package. To read the full review please visit Elrond's website.
The Passive House Planning Package (PHPP) can seem like a monster spreadsheet at 30+ worksheets (tabs). And the last thing most architects would consider a design tool. However, once architects understand passivhaus and start to design passivhaus buildings, they quickly realise that the passivhaus spreadsheet PHPP is an essential element of the design process. Sarah guides the reader towards fluency with the passivhaus spreadsheet PHPP using three key tools throughout the book:

The Flow Chart (as seen on the cover)
Camden Passivhaus, the first certified passivhaus building in London UK, is used throughout the book to give real-world context each step of the way. It is also a seminal bere:architects passivhaus project and one that Sarah worked on previously while as a Director of the practice.
The book starts with a brief overview of the passivhaus spreadsheet PHPP. It highlights that the PHPP, being a spreadsheet, is open and available for all to use with fairly basic software training in contrast to other energy modelling tools. Also underlined is that the PHPP is a design tool and not a compliance tool, and as such is strongly encouraged to be integrated into the design process, not contracted out.
The five chapters that follow cover specific aspects of using the passivhaus spreadsheet PHPP in depth; Getting Started, Heating Demand, Cooling, Primary Energy, and Heating Demand Details.
One of the key tools employed throughout the book is identifying Common Mistakes and highlighting them. Simple as this seems, these are incredibly powerful and useful tips. They point to crucial aspects of passivhaus design and forewarn you before you get tripped up in the passivhaus spredsheet.
This book will guide you through the process of becoming fluent with using the PHPP as a design tool. And even once you are fluent with the PHPP, this book is still a handy reference and well-illustrated guide.

A very good overview of design principles to consider whether designing to Passivhaus or not. Highly readable, and would be valuable to many students in my view. A manual that can only really be appreciated by running through the PHPP process at the same time, I found it interesting and valuable to read.
