Introduction to Passivhaus

What is Passivhaus? What performance can you expect and what comfort can you expect to feel. How will Warm help you achieve Passivhaus

Energy Standards Compared

WARM cover an array of energy standards. A guide to help you understand the pros and cons of different standards. How do you decide what energy standard to follow? What are the advantages of AECB or Passivhaus? how does it compare to Building Regs?

Intake Location Calculation (XLSX)

(Version 0.3)

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.

Carbon Reduction

PHRibbon can use all of the information you already have in your phpp with some additional information about materials and inform you about the buildings Carbon statistics. We use this at different stages to inform design decisions.

PHPP WARM Results Sheet (XLSM)

(Version 7.0.8)

A graphical results sheet that can be added to any v9 or v10 PHPP. Also includes a revision history, so you can record the impact of changes to the PHPP.

Note: the section where the U-value calculations can be displayed is not functioning. Otherwise, this version is functioning well.

Additional shading sheet (XLSX)

(Version 4.2.4)

An add-in sheet for PHPP 9 and 10, 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.

WARM U-Value Corrections Calculator (XLSX)

(Version 1.0.3)

Calculates corrections for:

• insulation moisture uptake in inverted roofs
• AAC conductivity when used below DPC. Also corrects for moisture uptake and for mortar fraction.
• screws passing through the insulation layer
  NB: only for screws. NOT suitable for other fixing types/brackets/penetrations. As of PHPP version 10, this calculation is now included as an auxiliary calculation in the PHPP U-values sheet.

Ducted hot water heat pump cold duct TB calculator (XLSX)

(Version 0.0.4 (Beta))

Calculates Psi-values for the intake and exhaust ducts to hot water heat pumps.

Note: this release is for testing purposes only.
