Hot on the heels of its launch of the eco-friendly CoolZone system, Armstrong Ceilings has introduced a RIBA-approved CPD on the use of the PCM (Phase Change Material) the concept is based on.
The CPD Using phase change materials in construction for a more sustainable built environment is designed to help architects, interior designers and clients better understand where and how PCMs can be used to create a more energy-efficient and comfortable environment and how they play a role in supporting high-performing sustainable properties.
Formulated specifically to meet the requirements of RIBAs core curriculum in terms of Climate: sustainable architecture and Designing and building it: design, construction, technology and engineering, the CPD advises on the how, what, where and when of PCMs in new-build and refurbishment projects in the office, education, healthcare, commercial and retail sectors particularly.
Armstrongs eco-friendly system, CoolZone, incorporates PCM into the companys plain metal ceiling tiles. This material microscopic polymer capsules containing a wax storage medium - is embedded in gypsum and then encased in the metal tile. On heating during the day and cooling at night, the wax melts and solidifies. In this way the internal temperature is regulated, ensuring a stable and comfortable environment in which to work.
In tests, the CoolZone tiles delayed the onset of air conditioning by approximately four to five hours in an average office. Not only can this save around 40% of the HVAC energy costs and reduce peaks in demand for air conditioning but it can also help to improve the thermal comfort for the occupants.
The CPD features before and after examples of the affects of PCM on rooms which feature natural ventilation, chilled ceilings and slabs, VRF and VAV systems and fan coil units. And case studies including a central London office building and a thermal test chamber are included.
The CPD also includes a video that brings the CoolZone concept to life.
