Story

With growing demand for universal, low profile tile vents, roofing ventilation and accessory specialist Klober has added the Twin Plain Tile Vent to its Profile Line® range. The vent is the seventh Profile Line® product and is ideal for use with Redland Duo Plain, Forticrete Gemini and Marley Ashmore tiles. Available in four standard colours, the Twin Plain Tile Vent provides an effective ventilation area of 7,850 mm2 and, in keeping with the rest of the range comes with a 10-year guarantee against manufacturing defect.

Other products in the Profile-Line range include the Double Roman, Single and Double Pantile, Standard Pattern, Large format Flat Tile and the Limarech (used with the Sandtoft Lindum / Marley Ludlow Major, Redland Renown and Russell Cheviot). The in-line design is virtually invisible from the ground and the products have been designed for universal use. Built-in downpipes allow direct ventilation to roof space while adaptors are available for soil ventilation or mechanical extraction.

Square detection zones provide 100% coverage grid with fewer detectors

The Sun Microsystems philosophy gets to the point: Sun solutions link up the world and demand integrated thinking, is the message in the multi-national computer group’s image brochure.

So it was clear to architects and planners that integrated thinking was called for in the design of the new Sun administrative building in Volketswil Hegnau, Switzerland – both visually and in terms of building technology. So it is that, over a floor area of 7000 m², a large number of Theben HTS presence detectors now ensure reliable and cost-effective operation of the lighting and ventilation system.

Theben HTS presence detectors from the ECO-IR C-Series, with their signature square detection zone and inrush current limitation for electronic ballasts, were used. The range is now available in the UK from Timeguard Ltd, a Theben company.

Sun has a flexible office philosophy which means that many of the staff no longer have fixed workstations: they simply log on wherever they happen to be. This means that the occupancy – and thus he lighting and ventilation requirements of different parts of the building are changing all the time and economic control involves responding to more than daylight levels and time of day. The use of sensitive presence detectors (instead of the rather blunt instruments that are traditional PIR detectors) enables the building managers to provide ideal combinations of lighting and ventilation levels for each building occupant at all times and with minimal energy consumption.

The specifier, Daniel Stadeli of Zurich-based Thomas Luem Partners realised that providing individual control of each room or area required the sophistication of HTS C-Series, which offer adaptive switching behaviour. In addition, their signature square detection area greatly simplifies planning. Using master-slave parallel circuit connections, he was able to design lighting for a large open plan office area with no gaps in presence detection. With more-traditional circular detection zones, almost twice as many detectors would have been needed to provide 100% coverage, he said.

Theben HTS C-Series presence detectors offer energy savings of up to 70% and are ideal for large areas such as Sun’s open plan office. They offer an 8m x 8m detection area with inrush current limitation to reduce peak currents and switching of up to 24 36-Watt electronic ballast.

Also particularly attractive in this range is the Quickfix system for flush mounting in hollow ceilings.

Fakro FTT and FPT 'Thermo' triple glazed roof windows have been chosen for use in four luxury eco homes being built by Marshall Robertson Associates’ at High Farm, Great Lumley. By providing the best U-value currently available in a standard product (0.94W/m2K), the windows will make a key contribution to the North East’s first ‘Code for Sustainable Homes’ Level 6 development. A combination of top hung and centre pivot windows will be fitted on the site which overlooks the Angel of the North, Lumley Castle and Durham Cathedral.

As well as achieving zero net carbon emissions, key aspects of the brief to architects Queensberry Design were provision of space and light and encouragement of a sustainable lifestyle. Other features include solar panels, rainwater harvesting and a wind turbine which will generate electricity to be fed back into the National Grid.

Architects Mountford Pigott have specified VMZINC PLUS® in QUARTZ-ZINC® to create a highly unusual design for the new McDonalds in Eureka Park Ashford. The system was chosen to provide a visually continuous warm roof across the curved span without unsightly ventilation details. Mountford Pigott’s Trevor Scale commented, “We chose zinc as a natural material for its aesthetic qualities and to provide an innovative and sustainable solution which was ideally suited to the building design. The brief was to develop a factory engineered pod design solution for a production run of similar shops”. The result will enable landmark design buildings using the latest in engineering methods to be provided.

Atkins' architects £29.7m North Liverpool Academy has seen Flag-Soprema Silver Art® PVC and Flagon TPO single ply membranes used to waterproof the roof. Silver Art was used on the predominantly curved roof to provide the aesthetic benefits of traditional metal roofing at greatly reduced cost. Aluminium particles are incorporated in the manufacturing process to give the membrane long-term colour stability while avoiding problems such as cold bridging, corrosion or water ingress at penetrations and details.

Flagon TPO AP/PR-F PVC membrane was fully adhered to the flat roof areas. With its BRE Green Guide A+ Rating, it retains exceptional flexibility and resistance to puncturing while remaining highly adaptable to structural movements. Being completely inert, Flagon TPO is non-toxic and has a life expectancy in excess of 30 years.

The simple, 'rectangular box' is split by a striking curved form at the centre, creating a spectacular external profile. The building combines the latest technologies with sustainable design to create a relaxed learning environment where the students can make the most of their learning experience. It houses 12 science laboratories, engineering workshops, a theatre, recording studios and teaching rooms equipped with the very latest in IT. The sixth-form common room and learning resource centre, dubbed the Learning Deck, sits within the highest point and enjoys panoramic views of the Liverpool skyline, the River Mersey and the distant Welsh mountains.
