The I-BPE framework

Development

Development

I-BPE originated from the Learn-BPE project.

To formulate the I-BPE methodological approach, the methods used for performance evaluation of buildings (BPE) or POE (i.e. post-occupancy evaluation) in India were considered along with those commonly used for BPE studies internationally and in the UK.

The elements of the framework

The elements of the framework

I-BPE provides five essential elements to achieving a comprehensive, yet simplified BPE study of a building in-use. This is the I-BPE framework which has been tested in several case study in India. What the authors determined to be five essential or ‘need-to-know’ study elements are shown in the diagram. 
 

This framework is necessary as the purpose and associated methods used for BPE or POE are highly case-dependent. It is difficult to have a standardized protocol for all POE projects. 

Defining the scope of an evaluation

Defining the scope of an evaluation

Each study element in the I-BPE framework adopts a graduated approach (from levels 1 to 4) of increasing complexity and detail. These levels can be seen by selecting any study element.


The size and scope of the evaluation will need to be planned.

 

In some cases, it won’t be possible to include all homes in a building or development, as not all residents will be willing to participate. Key things to consider when defining the scope of the evaluation:
•    Aim to cover all key housing types present: e.g. flat, terraced, and different sized units such as studios, 2-beds, 3-beds, etc.
•    Aim to address the range of construction techniques represented within the development.
•    Try to ensure a wide range of demographics are represented in the dwellings you work with (homes with small children, pensioners, adults who work at home and away, single-occupant homes, etc). 
It is a good strategy to start with a basic evaluation, and 'drill down' into detail only where it is worthwhile or necessary.
