Uses and case studies

What can I do with Purrmetrix? Some examples.

The Purrmetrix system is a versatile and flexible tool, used for a huge range of diagnostic, monitoring and benchmarking tasks.

Here are some examples of common ways our customers use Purr to improve the performance of their buildings and projects. New applications are emerging all the time so we’ll be updating this on a regular basis.


Using live views to triage ‘too hot/too cold’ complaints and identify the most appropriate course of action. Purr has reduced ‘too hot/too cold’ complaints by 20% in some customers’ estates

By collecting environmental and space use data, Purr can reduce or eliminate ‘clipboard’ monitoring tasks, for example cleaning delivery or water temperature testing. Allowing more reliable services to be delivered when they are needed.

Using motion sensors to capture and analyse usage of all areas in buildings. Identifying opportunities to reduce space used or repurpose space that is underused.

Tracking the performance of buildings in supporting wellbeing and productivity. Identifying shortfalls and areas for action.


Using Purrmetrix tools (‘just in time’ and heatmaps) customers identify energy wasted when buildings are heated or cooled outside operating hours. Saving energy reducing run time needed to bring buildings to optimum conditions ready for occupation.

HVAC systems that fight themselves – because zones are at different temperatures or because there’s no dead band between heating and cooling systems – waste energy. Purrmetrix ‘hotspotter’ tool helps identify regions that are persistently out of spec and which need attention.

Using Purrmetrix tools to identify and reduce heating and cooling in unoccupied space.

Benchmarking areas of excessive heatloss or gain in building envelope that may increase energy consumed to achieve the right conditions.


Using Purrmetrix analytics to provide an estimate of a home’s risk of condensation, for more efficient interventions.

Providing an indication of the most likely causes of the condensation problem to help customers decide what interventions to take.

Monitor vulnerable groups to check if their health is at risk from poor environments.

Benchmarking areas of heatloss to indicate the effectiveness of upgrades to the building’s fabric.
