Chicago trip up for grabs


invited from all recent graduates in a building services related discipline. Now in its 16th


T year the award


scheme, which is sponsored by Baxi Commercial, will once again reward its winner with a trip to the ASHRAE Winter Conference in the USA. This year the venue is Chicago where the fortunate graduate engineer will be a guest of honour. Two runners up will also receive generous cash prizes donated by the Rumford Club. CIBSE and ASHRAE are inviting


graduate engineers from all over the world to enter for this year’s award. They must have graduated within the past two years and seek a supporting nomination from either an employer or their university or college. The closing date for entries is 29th


July 2011 after which a shortlist will be drawn up and those selected invited to give a short presentation to a dis- tinguished judging panel at the Institution of Mechanical Engineers (IMechE) on 6th


October 2011. This year’s judges include ASHRAE


President Ron Jarnagin; CIBSE President Andy Ford; and IMechE president Roderick Smith. Following the judging Mr Jarnagin will deliver the annual ASHRAE Lecture to the UK industry and there will be an evening reception hosted by CIBSE Young Engineers’ Network.

K


onserve Limited, which launched the Drainwave™


in-line flushing device at Ecobuild in February, is an innovative device


that collects waste water from building use (basins, washing machines, showers) and combines this with water from the toilet to increase the flush volume down sewage pipes. The Drainwave™ stores the water temporarily and once it has reached a predetermined capac- ity (9.5 litres) automatically tips, which sends the water surging through the pipes. The device is stored under- ground near the building and contains only one moving part, so it requires little or no maintenance. Investigations have shown that con-


cerns regarding reduced WC flush volume and sewer solid movement were justified. A significant reduction in WC flush volumes, for example to a 4½ and 3 litre dual flush combination, is likely to be unacceptable if no other measures are taken to counter the effect of the reduced flush. A report carried out by the WRc on


Government (DCLG) Minister Andrew Stunell to its Garston offices recently. The Minister, having trained in archi- tecture, is therefore familiar with Agrément Certificates and was inter- ested in the test equipment that pro- vides the data that underpins these. Some of this equipment is also in use in support of the joint BBA / Industry / NHBC Foundation Warm Roof project, involving measurement of insulated roof structures in dynamic installations where the effects of wind on the roof are taken into consideration. The Minister was also shown the

recognises that the Drainwave™ product is a solution to the problem. Using the Drainwave™


as a device to


‘flush’ the system is a viable and prac- tical solution. This is a patented adap- tation of the flushing methods originally used by Victorian engineers to keep the main sewers clean. These proven devices typically collect grey water discharges, temporarily store them and discharge when an adequate volume has been collected. The flush or washdown volume is 10 litres (or more) with a velocity greater than that induced by WC’s. The washdown effect was sufficient to clear stranded solids through the tested bed distance of 25 metres. Installation of the Drainwave™


can


prove a mitigating measure. The Drainwave™


provides the volume and


velocity in intermittent doses, which is equal or greater than the “lost” or “saved” WC flush volume. The Drainwave™ flow amplifier device is a tipping bucket contained within a pre- formed, moulded housing of UPVC construction. It is designed to be installed in the building drainage system immediately upstream of a WC connection and to deliver a measured volume of water to re-entrain solids deposited in the small diameter down- stream drain. The housing is shaped so as to


deliver a double peaked flush wave, of 10 litres, of grey water collected from wash basins, showers and baths.

industry news A


New version of Shaderlight gives architects & designers the winning edge


new version of the leading inter- active rendering plug-in for Google SketchUp has been


launched, with a range of unique fea- tures for architects and designers. Offering a host of new features, Shaderlight 1.3 has been developed incorporating feedback from architects and designers across the globe, wanting to create photorealistic 3D images for client presentations. An innovative raytracing plug-in to


Google SketchUp, the new release builds on the compelling feature set that has already made Shaderlight the first choice SketchUp renderer for thousands of architects around the world. Interactive rendering allows the user to watch their image develop as they work and the simplicity of the software allows any SketchUp user to easily take their 3D models to the next level. This latest version also offers improved handling of SketchUp components and groups as well as significant gains in the interactive per- formance of SketchUp whilst Shaderlight is rendering. New fea- tures introduced to Shaderlight include a SketchUp Parallel Projection Camera to create photo-realistic images of elevations and plans; ideal for use with Google Layout presenta- tions. The new "Chalk Render" mode allows Shaderlight users to produce form studies with ease. Six professional quality Imaged

Minister Andrew Stunell commented: “I always appreci- ate getting out and about and seeing for myself at first hand what industry itself is doing to further improve its work in complying with our important Building Regulations. The British Board of Agrement is making great strides in achieving high levels of compliance, which will be crucial if we are to meet our carbon reduction commitments.” The BBA's Chairman, Digby Harper


and Chief Executive, Greg Cooper, together with members of the man- agement team, also discussed a number of issues relevant to achieving high levels of as-built thermal perform- ance with the minister and the CLG staff who accompanied him, including the BBA/TIMSA U-Value and Condensation Risk Competency


Scheme and the existing schemes run by the BBA for injected cavity wall insulation and as contractors to FENSA for the installation of replace- ment windows and doors.


Based Lighting (IBL) environments and backgrounds provided by leading sup- plier of high dynamic range images (HDRI) Moofe®


have also been added,


along with 90 complimentary profes- sionally photographed custom back- grounds to further enhance the photo-realistic lighting functionality. Kate Marshall, marketing director at


Shaderlight, said: “We are continuing to develop Shaderlight at a fast pace to ensure SketchUp users have the very best rendering tools at their fin- gertips. A large number of our cus- tomers are architects and designers, many of whom are facing increasing pressure to deliver high quality, photo realistic images for client presenta- tions. Shaderlight gives them a simple and fast means to make this happen. The additional features now available give users even more options to make their renderings stand out from the competition.”
