PHeasibility


Are you working on a house design for yourself or for a client?

Have you wondered if your design could meet the international Passivhaus Standard?

PHeasibility is for you.

This is a fixed price Passivhaus feasibility study for early stage sketch designs. For a Passivhaus project, there is nothing worse than developing a design to an advanced stage before carrying out a Passivhaus check. And then trying to shoe-horn Passivhaus into the project. It’s an ugly and expensive process in my experience.

If you are certain that your project will be certified to the international Passivhaus Standard, you should employ a certified Passivhaus Designer or Consultant from the beginning. They can advise you on how to achieve the best outcome within the project constraints – aesthetic, financial, materials etc.

However, if you have already started your design and you’re not absolutely certain about it meeting the international Passivhaus Standard, PHeasibility is for you.

Here’s how PHeasibility works.

    1. You send me your dimensioned sketch design drawings and outline specification along with some other important details such as the project location. (Exact requirements will be advised when you book a PHeasibility.) Single family residential detached projects up to 300sqm gross external area only.
    2. I carry out an expert review of your current design and build a sketch model of the design in the Passivhaus Planning Package to assess it.
    3. I provide you with a report of the Passivhaus feasibility of your project within 14 days (2 calendar weeks). The report will be in metric units, even if your project is in IP units.
    4. You will then know the predicted performance of the current design and how likely it is to achieve the international Passivhaus Standard. You will also know what you will need to do if you wish to pursue Passivhaus – such as the required specification for the floor, walls, roof, and glazing, specific your project.

There’s no obligation beyond the report, you can choose whether or not you wish to pursue Passivhaus certification for your project. (And please note, we may advise that your current design is not suitable to achieve Passivhaus!)

If you do wish to pursue Passivhaus certification, you can contact me to discuss further Passivhaus Design services, or you can approach another Passivhaus Designer or Consultant. You’ll be educated about the Passivhaus potential of your project and armed with a useful report either way.

The PHeasibility Report

The report will be around 5 pages long and will include the following:

  • If the current design is likely to be able to meet the requirements of the international Passivhaus Standard
  • Predicted performance of the current design
  • Advice on the current form, shape and orientation
  • The required glazing performance
  • The required wall, roof and floor performance
  • Screenshots / graphs / data extracted from the PHPP model

Limitations

  • New build single detached residential project (For refurbishments and extensions, please contact me to discuss if it’s possible to do a PHeasibility)
  • Floor area up to 300sqm gross external area total (For larger projects please contact me to discuss the cost)
  • The PHPP file is not issued with the report (Although see upgrade options below)
  • All calculations and reports will be in English and use Metric units (Your drawings can be in IP units, though)
  • Primary Energy or Primary Energy Renewable will not be calculated

Requirements

  • Sketch design drawings to scale with orientation and key dimensions in PDF format or a 3d digital model (for example, a SketchUp file) subject to our agreement
  • Outline specification describing the intended construction of key elements. For example; timber frame, SIPS, ICF, preferred insulation material, window frame type, etc..
