Monodraught and IES to Create New Cool-Phase and Sunpipe Performance Components

Share Article

To help architects and consultants deliver low maintenance, energy efficient designs within the built environment, building performance analysis specialist IES and Monodraught are developing two further ranges of Performance Components which are due to be released within VE 2013 in spring next year.

The use of building performance analysis has grown extensively in the last 10 years, driven by the development of computer simulation and legislative requirements to reduce the energy consumption of buildings. Monodraught pioneered the COOL-PHASE® natural cooling system and SUNPIPE® natural daylight systems, but modelling these types of systems has been considered time consuming and complicated. The new Cool-Phase and Sunpipe Performance Components for the IESVE (Virtual Environment) will change all this.

Monodraught’s COOL-PHASE® natural cooling system is a low energy cooling and ventilation system that creates a comfortable, fresh and healthy indoor environment and reduces the running costs of buildings. COOL-PHASE uses a thermal energy store utilising Phase Change Material (PCM) in combination with an intelligently controlled Air Handling Unit. The system can maintain temperatures within the comfort zone, while radically reducing energy consumption compared to conventional cooling systems.

Monodraught’s SUNPIPE® natural daylight system directs sunlight into a room from roof level. The SUNPIPE collects daylight using a patented Diamond dome, using a silverised PVD coated mirror-finished aluminium tube to transfer light to a room, with a ceiling diffuser evenly distributing the light around the room.

At present, architects and consultants find it difficult to verify the improvements achieved within their buildings, and therefore understand the true environmental impact of the Cool-Phase and Sunpipe systems. Conventional modelling of these systems involves constructing a 3D representation and assigning performance factors for the materials used to relate to the performance the systems will provide. Assigning such parameters is often time consuming and can be difficult to ensure that the true systems performance is replicated within the 3D model.

Like the WINDCATCHER® natural ventilation performance component released in VE2012, Monodraught envisaged true 3D component representations of their systems being dragged easily from a product library/ catalogue onto a building model constructed within the 3D environment. The performance and energy savings would then be assessed in an open and transparent process, building confidence in the application of Cool-Phase and Sunpipe systems and demonstrating the potential and capabilities of their approaches. The 3D components would have the full representation of shape, texture and colour, with performance characteristics already assigned.

As a global provider of building analysis and simulation software, IES has the expertise to transform this vision into the Cool-Phase and Sunpipe Modules which will be launched as part of the Performance Components library within its award winning VE software.
