A false ceiling conceals Cool-Phase
in the commercial applications where the requirements can be more stringent,’ says Mathew Holloway, product manager for Cool-Phase. ‘Here we are seeing that the system, when used alongside conventional HVAC solutions, can reduce the capital costs of new builds and refurbishments, reduce on-going running costs and improve the quality of the indoor environment. It’s this kind of win-win situation which means, I believe, that we will see a lot more of Cool- Phase in our buildings in the future.’ Certainly Monodraught can point to some impressive results so far. The company trialled Cool-Phase at Notre Dame School in Southwark, London, in an IT classroom that regularly suffered from overheating problems from internal and external heat gains (see case study opposite). ‘I regularly teach in this classroom
during the afternoons. The girls are normally using the computers and when the sun comes round it can get incredibly hot,’ says Notre Dame’s deputy headteacher Jocelyn Lewis. ‘Since we have had the Cool-Phase
system installed, it has had a massive effect on the girls and their learning. There has been a marked improvement in terms

of temperature; it’s much cooler and the environment is much more conducive to learning. There has been a profound effect; the students settle much more quickly and there is a much more focused start to the lesson.’ Lewis also compared Cool-Phase favourably with air conditioning, which is installed in some other classrooms in the school. ‘There have been no complaints, which is evidence in itself,’ she says. ‘Elsewhere we have air conditioning installed and students sitting underneath the air conditioning get too cold. With the Cool-Phase system we don’t have any of that dialogue with the students – I’m too hot, I’m too cold. It’s much easier to teach in this classroom now.’ The fact that Cool-Phase uses less energy
than traditional air conditioning and doesn’t contain harmful refrigerants also provides an important lesson. ‘As a school, we give a strong message that we should be looking after our environment,’ says Lewis. ‘With the Cool-Phase system we can tell the students within the school about how green it is and the difference that we are making as a community. I think it is a really positive message for the students.’ CJ
