Man 05 Aftercare

Number of credits available Minimum standards



To provide post-handover aftercare to the building owner/occupants during the first year of occupation to ensure the building operates and adapts, where relevant, in accordance with the design intent and operational demands.

Assessment criteria

This issue is split into three parts:

The following is required to demonstrate compliance :

One credit - Aftercare support

  1. There is (or will be) operational infrastructure and resources in place to provide aftercare support to the building occupier(s), which includes the following as a minimum:
    1. A meeting programmed to occur between the aftercare team/individual and the building occupier/management (prior to initial occupation, or as soon as possible thereafter) to:
      1. Introduce the aftercare team or individual to the aftercare support available, including the Building User Guide (where existing) and training schedule/content.
      2. Present key information about the building including the design intent and how to use the building to ensure it operates as efficiently and effectively as possible.
    2. On-site facilities management training, to include a walkabout of the building and introduction to and familiarisation with the building systems, their controls and how to operate them in accordance with the design intent and operational demands.
    3. Initial aftercare support provision for at least the first month of building occupation, e.g. on-site attendance on a weekly basis to support building users and management (this could be more or less frequent depending on the complexity of the building and building operations).
    4. Longer term aftercare support provision for occupants for at least the first 12 months from occupation, e.g. a helpline, nominated individual or other appropriate system to support building users/management.
  2. There is (or will be) operational infrastructure and resources in place to coordinate the collection and monitoring of energy and water consumption data for a minimum of 12 months, once the building is occupied. This is done to facilitate analysis of discrepancies between actual and predicted performance, with a view to adjusting systems and/or user behaviours accordingly.

One credit - Seasonal commissioning

  1. The following seasonal commissioning activities will be completed over a minimum 12-month period, once the building becomes substantially occupied:
    1. Complex systems - Specialist Commissioning Manager:
      1. Testing of all building services under full load conditions, i.e. heating equipment in mid-winter, cooling/ventilation equipment in mid-summer, and under part load conditions (spring/autumn).
      2. Where applicable, testing should also be carried out during periods of extreme (high or low) occupancy.
      3. Interviews with building occupants (where they are affected by the complex services) to identify problems or concerns regarding the effectiveness of the systems.
      4. Re-commissioning of systems (following any work needed to serve revised loads), and incorporating any revisions in operating procedures into the operations and maintenance (O&M) manuals.
    2. Simple systems (naturally ventilated) - external consultant/aftercare team/facilities manager:
      1. Review thermal comfort, ventilation, and lighting, at three, six and nine month intervals after initial occupation, either by measurement or occupant feedback.
      2. Take all reasonable steps to re-commission systems following the review to take account of deficiencies identified and incorporate any relevant revisions in operating procedures into the O&M manuals.

One credit - Post occupancy evaluation

  1. The client or building occupier makes a commitment to carry out a post occupancy evaluation (POE) exercise one year after initial building occupation. This is done to gain in-use performance feedback from building users to inform operational processes, including re-commissioning activities, and maintain or improve productivity, health, safety and comfort. The POE is carried out by an independent third party (see Man 01 Project brief and design – Relevant definitions) and needs to cover:
    1. A review of the design intent and construction process (review of design, procurement, construction and handover processes).
    2. Feedback from a wide range of building users including Facilities Management on the design and environmental conditions of the building covering:
      1. Internal environmental conditions (light, noise, temperature, air quality)
      2. Control, operation and maintenance
      3. Facilities and amenities
      4. Access and layout
      5. Other relevant issues
      6. Sustainability performance (energy/water consumption, performance of any sustainable features or technologies e.g. materials, renewable energy, rainwater harvesting etc.).
  2. The client or building occupier makes a commitment to carry out the appropriate dissemination of information on the building’s post occupancy performance. This is done to share good practice and lessons learned and inform changes in user behaviour, building operational processes and procedures, and system controls.
    Refer to compliance notes CN3.1 and CN3.2 for a definition of appropriate dissemination. This also provides advice on appropriate dissemination where the building or building information is commercially or security sensitive.

Exemplary level criteria

The following outlines the exemplary level criteria to achieve one innovation credit for this BREEAM issue:

  1. There is (or will be) operational infrastructure and resources in place to coordinate the following activities at quarterly intervals for the first three years of building occupation:
    1. Collection of occupant satisfaction, energy consumption and water consumption data.
    2. Analysis of the data to check the building is performing as expected and make any necessary adjustments to systems controls or to inform building user behaviours.
    3. Setting targets for reducing water and energy consumption and monitor progress towards these.
    4. Feedback any ‘lessons learned’ to the design team and developer for use in future projects.
    5. Provision of the actual annual building energy, water consumption and occupant satisfaction data to BRE.

Checklists and tables


Compliance notes




Shell and core


Applicable assessment criteria This issue is not applicable.
Simple buildings


Applicable assessment criteria All criteria relevant to the building type and function apply.


Collection and monitoring of energy and water consumption data
See criteria 2 and 4.

This function can be coordinated/carried out by a dedicated aftercare team or, where the building occupier is known and able to confirm compliance based on their existing or proposed operations for the building, the building owner/occupier’s estates/facilities management team.


Appropriate dissemination of post occupancy evaluation information

See criterion 4.

1. Appropriate dissemination includes communication to immediate stakeholders such as building occupants, managers and owners.

In addition information should be communicated externally.

2. Appropriate dissemination in most cases will be the production and publication of a building case study through one of the following means:

  1. Client’s/building owner’s own website, publicly available literature or press release
  2. Industry/sector or government/local authority sponsored website or information portals.

Where there is a demonstrably justifiable reason why public dissemination is not possible, for example the information is commercially or security sensitive, compliance can be demonstrated by a commitment to produce and disseminate the relevant information at an organisational level or to appropriate internal/external stakeholders. Alternatively, the sensitive parts of the relevant information for dissemination can be omitted from the publication.


Relevant information for dissemination

See criterion 4.

This includes the following information about the building and its performance:

  1. A basic description of the project and building
  2. BREEAM rating and score
  3. The key innovative and low-impact design features of the building
  4. Project cost
  5. Project size: floor area, site area
  6. Facilities available for community use (where relevant)
  7. Any steps taken during the construction process to reduce environmental impacts, i.e. innovative construction management techniques
  8. Predicted and actual carbon dioxide emissions and/or Energy Performance Certificate rating.
  9. Outcomes of the post occupancy evaluation study, to share lessons learned from the project including:
    1. Occupant feedback
    2. Energy and water consumption including renewable energy generation, level of rainwater/grey water provision.


Provision of annual energy and water consumption and occupant satisfaction data
See criterion 4.

One way of demonstrating compliance with this criterion is for the client/end user to register and therefore commit the building for assessment under the relevant part of the BREEAM In-Use scheme.




Criteria Interim design stage
Final post construction stage

One or more of the appropriate evidence types listed in The BREEAM evidential requirements section can be used to demonstrate compliance with these criteria.

1 Refer to generic evidence requirement above Contract to provide compliant aftercare support and training
2 Refer to generic evidence requirement above Seasonal commissioning records/reports and letter of appointment

Additional information

Relevant definitions

Complex systems
These include, but are not limited to, air-conditioning, mechanical ventilation, displacement ventilation, complex passive ventilation, building management systems (BMS), renewable energy sources, microbiological safety cabinets and fume cupboards, cold storage enclosures and refrigeration plant.
Specialist Commissioning Manager
The Specialist Commissioning Manager is a specialist contractor rather than a general sub-contractor.
Independent third party
To comply with criterion 4 relating to the use of an independent third party, the client/design team needs to demonstrate either of the following options:
  1. They have used a third party independent of the design process to conduct the necessary Post Occupancy Evaluation exercise using a compliant method. Or alternatively;
  2. If the Post Occupancy Evaluation is to be carried out by an organisation involved with the design of the building e.g. the project architect, then they must present the assessor with the evidence that demonstrates the independence of the Post Occupancy Evaluation process from the design process. BREEAM has not attempted to define what form this exercise must take, the onus is on the design team/relevant individual to clearly demonstrate to the BREEAM assessor a credible level of independence.
Actual vs predicted performance
In most cases it is not feasible to accurately compare predicted vs actual performance due to variances in the assumptions used in predicted vs actual models. Figures reported via the Carbon Buzz website show that on average, buildings consume between 1.5 and 2.5 times predicted values. When comparing predicted with actual, an analysis should be carried out to understand why there may be discrepancies in performance. These discrepancies can be for a number of reasons including: CIBSE TM54, Evaluating Operational Energy Performance of Buildings at the Design Stage, CIBSE, 2013 provides guidance on how to improve the accuracy of the model for operational energy use of buildings at the design stage. The Carbon Trust guidance, ‘Closing the gap: Lessons learned on realising the potential of low carbon building design’, also provides additional guidance on this issue.
Absence of predicted performance data
Where building occupiers do not have predicted performance models, it may be more appropriate to benchmark actual building performance data with other sources of Building Performance Evaluation Data and benchmarks. Sources of benchmarking information can be found here:
Building performance benchmarks can be found in CIBSE Guidance including: Actual building performance data can also be found here:
Post Occupancy Evaluation Methodologies
The BUS methodology was developed following a series of government funded ‘PROBE’ building performance evaluation studies in 1995. The BUS methodology is used by independent licensed partners following a four part process. Further information can be found at
BRE’s Design Quality Method (DQM) is a tried and tested, independent, post occupancy evaluation (POE) method used by all UK auditing authorities, and many funding bodies. Further information can be found at
