IPMS Coalition invites your feedback on the draft international measurement standard for residential buildings

Dear FIABCI Member,

This month the IPMS Coalition – a group of more than 60 professional and standards-setting organisations from around the world – has launched a consultation on the new International Property Measurement Standard, IPMS: Residential Buildings.

IPMS: Residential Buildings is being developed by the Coalition to establish a common, international methodology for measuring residential property. It seeks to address existing inconsistencies in measurement practices between and even within markets, which can lead to confusion for consumers and the inability to compare property on a like-for-like basis. IPMS: Residential Buildings will enhance transparency and consistency in property data.

IPMS: Residential Buildings is the second in a suite of International Property Measurement Standards and follows the November 2014 launch of IPMS: Office Buildings. Once published, Coalition organisations have committed to implementing the new standard. Further standards will be created to address industrial, retail and mixed use property.

Creating a market-leading international standard is no easy task. The Coalition has appointed 18 independent experts to lead this work with input from across property markets worldwide. The Coalition organisations recognise the vital importance of gathering extensive consultation feedback in order to deliver something that is fit for purpose and best in class.

On behalf of the entire Coalition I invite you and your business to review the consultation draft and to offer your valuable feedback.  A copy of the IPMS: Residential Buildings consultation is included with this letter. You can also access an online version, along with a feedback form through the Coalition’s website: www.ipmsc.org.

Responses should be sent electronically to consultation@ipmsc.org. The consultation will close on Wednesday 30 September 2015.

To support the consultation, the expert committee leading the technical drafting has proposed a standard feedback form and a series of questions for consultees to consider. These questions can be found below:

In addition to commenting on individual elements contained within the Consultation Document, the IPMS SSC would also appreciate your response to the following questions:Q1. IPMS: Residential Buildings is intended to improve market transparency for consumers. Does the document achieve this and if not what improvements would you suggest? 

Q2. Which of the standards IPMS 1, IPMS 2 Residential and IPMS 3A, 3B and 3C Residential would be relevant to your markets?


Q3. How would you use IPMS 1, IPMS 2 Residential and IPMS 3A, 3B and 3C – Residential within the markets in which you operate?


Q4. Within your residential market are there other measurement issues that the IPMS Residential Standard has not mentioned or clarified that you believe should be part of the IPMS Residential Standard?


Q5. IPMS: Residential Buildings has adopted Internal Dominant Face in order to maintain consistency across all IPMS Standards. Please advise whether you support this or whether you have an alternative proposal and if so what is it and why? How would you address the resulting inconsistency with IPMS Office Buildings?


Q6. Are the explanatory diagrams and text description for Internal Dominant Face sufficient? If not, what specific diagrams or explanation do you require?


Q7. Are all other diagrams clear in demonstrating the concepts to which they apply?


Q8. IPMS: Residential has adopted Level 0, Level 1 and Level 2 to denote what in some markets would be called ground, first and second floor and in other markets floor 1, 2 and 3. Will this approach be understood in your market?


Q9. IPMS 1 currently excludes ground floor patios from the total measurement, as the ground floor is not actually part of the building structure, although they can be measured and stated separately.  A similar upper floor balcony is however included, as it forms part of the building structure, albeit is stated separately. Do you have any comments on this approach?


Q10. Do you have any other comments?

Yours Sincerely,

Terry Dunkin

President, FIABCI World Council of Experts
