If you would like a quote for Passivhaus certification of a residential project please fill out this form and return it to us, together with the drawings of the project.
Certification checklist for use during design stage. Note that this lists typical requirements only, and the evidence required on each project varies according to construction type, size, junctions and products used.
Certification checklist for use during construction stage. Also, declaration to be signed by site supervisor.
Glazing and frame evidence required for certification of Passivhaus buildings. Window suppliers, please upload the requested reports to your website for download.
Sheet for window manufacturers to provide glazing and frame specifications. Also denotes the evidence requirements for these specifications.
A graphical results sheet that can be added to any v8 or v9 PHPP.
An add-in sheet for PHPP 9, which allows you to easily model shading objects that are discontinuous and/or which have transparency. These include trees, tower blocks, brise-soleils, juliet balconies and plant-on glazing bars.
Calculates corrections for:
- insulation moisture uptake in inverted roofs
- metal fixings passing through the insulation layer.
- AAC conductivity when used below DPC. Also corrects for moisture uptake and for mortar fraction.
A tool for comparing the outputs of different PHPP sheets that are both open. V8 and V9 now supported.
Converts boiler efficiencies from gross (SEDBUK) to net for use in PHPP.
An add-in sheet for the PHPP. When you are comparing the impact on your PHPP of windows/doors from different manufacturers, use this sheet to save you from copying and pasting new specifications into the Components sheet every time you wish to switch to a different window manufacturer. Simply use the drop-down box in this sheet instead.
Shows you how to enter multiple compact units in one PHPP.
Use this tool at very early design stage to tell you the approx. U-values you will need for floor/wall/roof. The Shape Tool doesn't reflect the changes in internal gains within calculations on PHPP9, but is still generally applicable.
As Sally's presentation at the PHI conference 2106: An Updated Final Protocol Worksheet and Commissioning Instructions. These are based on the difficulties we have found with ventilation systems in the the UK, and make specific suggestions about how the commissioning process should be carried out, including:
- the ability to declare the system "un-commissionable" if noise and airflow measurements cannot find acceptable values
- the list of suitable types of anemometers for various measurements
- Noise estimation for high background noise sites.
- Testing where duct leakage needs to be established.
On many projects we need to decide how close we can locate an air intake to a polluting exhaust or boiler flue. This workbook is for calculating the minimum recommended distances between intake and exhaust openings and boiler flues using the equation provided in Annex A of BS EN 13779: "Ventilation for non-residential buildings - Performance requirements for ventilation and room-conditioning systems". Note that this calculation does not take into account directional louvres.
