London’s Riverwalk incorporates Passivhaus standard Schöck Isokorb

On the north side of the Thames in central London, the three riverside embankments, Chelsea, Victoria and Albert, are the result of extensive civil engineering works that reclaimed marshy land, narrowed the width of the river and provided a large-scale new area of development during the late 19th century.    Today almost 150 years later, much of the area is once again being transformed as the result of a scheme designed to replace many of the outdated buildings which have characterised these areas for so long. There will be high specification property construction, promenades and parks; and at Millbank, one of the major residential riverfront developments is Riverwalk.

Passivhaus standard Schöck Isokorb

Riverwalk features two organically shaped buildings of seven and seventeen storeys, connected by a central podium and incorporating 116 high specification one, two, three and four bedroom apartments, plus penthouses. The design focus is on light, space, service and exceptional views across the Thames.   Aesthetically the buildings are enhanced by horizontal bands of limestone on the curving facades between the glazing and ceramic panels, with the stonework wrapping around the lower parts of the balconies to create a continuous organic shape.

The avoidance of thermal bridging is critical

With such a high specification development, early consideration was given to the avoidance of the thermal bridging at the critical balcony connections. Thermal bridges would result in higher heat transfer through the assembly and colder surface temperatures on the warm side of the assembly.

Some of the consequences of this being higher energy use for heating and cooling, non-compliance with UK Building Regulations, potential building structure corrosion and the risk of mould growth and associated health concerns from respiratory problems. To help minimise any risk of thermal bridging, the structural thermal break module specified throughout the Riverwalk development is the latest generation Schöck Isokorb for concrete-to-concrete applications, the type KXT.

Isokorb type KXT

This latest example of Schöck engineering means even better performance, which is critical in meeting the inceasingly stringent EU guidelines and the imminent need for nearly zero-energy building standards. The Schöck Isokorb type KXT pushes the technical boundaries in meeting these demands.

In addition, through close collaboration with its clients, Schöck has also now optimised the load capacity of the Isokorb range. As a result, the load capacities most frequently in demand have been identified and appropriate refinements applied to the product portfolio.   The range now provides planners with not only a structurally optimised product solution for the construction of cantilevered components, but cost advantages as well.

Verifiable performance values

The product offers such a high level of insulation, that in Germany the Passivhaus Institute in Darmstadt has awarded the product with the low ‘thermal bridge construction‘ certificate and confirmed its suitability even for Passivhaus construction. The product has also just been awarded the very latest BBA certification.   All units meet full compliance with the relevant UK building regulations, which require that the temperature factor used to indicate condensation risk (fRSI) must be greater than or equal to 0.75 for residential buildings. The range also provides Local Authority Building Control Registration and there is compliance too with the UK government Standard Assessment Procedure (SAP 2012) concerning CO2 emissions from buildings and respectively heat losses through non-repeating thermal bridges.

Here, the lambda values of the Schöck Isokorb enable energy loss in various connective situations to be reduced by as much as 84% to 91%.

Washroom design for the well educated

With so many rules and regulations surrounding the practicalities of washroom design in educational settings, Daniel Ward, Senior Ceramics Product Manager for Twyford, talks us through the dos and don’ts of sanitary specification for the school environment.

Specifying products for washrooms within the education sector may seem like a fairly straightforward task, but there are a number of considerations that need to be taken into account to ensure not only that regulations are met, but that the space is well designed, comfortable and practical.

Lack of privacy, vandalism and inadequate cleaning and maintenance can make a visit to the toilet an unpleasant and unhealthy experience for students. In fact, recent research undertaken by charity Education and Resources for Improving Childhood Continence (ERIC) highlighted that the quality of school toilets has a huge impact on pupils’ health, education and happiness. Therefore the design of washrooms in education premises needs to be about a lot more than simply providing enough toilets and washbasins.

Laying out the order

The overall layout of school washrooms is a good place to start. As well as adhering to regulations regarding wheelchair accessible cubicles, all standard cubicles must have a minimum 450mm-diameter manoeuvring space that is clear of the door swing. And of course, when you are designing spaces for growing children, the sizes and fixing heights of sanitaryware must be suitable for the relevant user age groups too. Short projection WCs offer a good solution here, creating the necessary space while still ensuring user comfort. Wall-mounting the pan with a suitable framing system will enable the height of the WC to be easily adjusted during installation, to better meet the needs of the user.

Hygiene first

Aside from layout, hygiene in this environment is extremely important too, with ease of cleaning being key to students’ health and wellbeing. So much so that the Department for Education offers guidance on the issue, stating that to avoid build-up of dirt and germs, the toilets in schools should be wall-hung or back to wall.. This also offers a solution with regards to ensuring plumbing work is tamper-proof, a particular point of note when specifying for colleges and universities which serve older children and young adults. The cistern and pipework concealed within the framing system, preventing interference, while being easy to access for maintenance purposes. A dual-flush cistern sitting neatly behind the wall will also help to significantly reduce the amount of water used, while not affecting overall flushing performance. This is particularly important in educational establishments, which are high-traffic areas with the potential for toilets to be flushed literally hundreds of times in any one day.

It is also worth noting that in schools, particularly where younger users are present, the recommendation is also to avoid urinals, but where they are specified to opt for individual bowls rather than a trough, with modestly panels for privacy.

Twyford offers a Rimfree school pans and Flushwise water-efficient WC flushing options.

Water-saving pays off

The washbasins in school washrooms should also be subject to a number of practical considerations. Of course, ease of cleaning for hygiene reasons remains imperative, making ceramics that are coated with an easy to clean glaze a particular benefit, while the choice of brassware is also important. Not only should mixer taps for washbasins be robust and tamper-proof, ideally they should be fitted with an automatic shut-off too, either through a built-in timed delivery feature or infra-red sensors.

Energy and water are a major proportion of non-staff costs in schools, colleges and universities and a major part of their environmental impact. While some schools will have greater scope for savings than others, overall more than 20% of energy is wasted, and a school that is equipped with water conservation devices, such as taps with automatic shut-offs or flow restrictors, plus dual-flush WCS, typically use less than half the amount of water used in schools where such features are not present.

Longevity guarantee

Keeping maintenance levels as low as possible is an important requirement in school buildings, where downtime in washrooms can be at best inconvenient for staff and students. This makes the specification of quality sanitary fittings that will be hard-wearing and durable, of particular significance. To limit the frequency of replacing such fixtures and fittings, their life expectancy should be around 15-20 years, with a manufacturer’s guarantee providing the best scope for this.

There are undoubtedly a lot of things to consider when designing washrooms for educational establishments, with all elements really carrying an equal weight of importance. The trick to ticking all of them off and achieving a successful design is to establish a strong relationship with a manufacturer who is able to respond to all aspects of a washroom’s design, from layouts and dimensions to styles and materials as standard, so that there is never any need to compromise.

Mark this renewable day in your diary and celebrate

by Russell Jones ~ Communications Manager at Mitsubishi Electric

Russell Jones asks whether a whole day of electricity produced without burning a single lump of coal spells out the end of an era for the nation.

Last Friday, 21st April 2017 was a very special day for the UK as the country generated a whole day of electricity without needing to use coal-fired power stations.

This landmark moment is the first working day in since 1882, when the first public coal-fired generating plant opened in London when no coal has been needed to help supply power to the nation – as reported by many news outlets such as the BBC and the Financial Times.

Whilst low demand for electricity in the week after the Easter holiday is quite normal and Friday’s are the day of the working week with the lowest power demand, this move away from what has been a bedrock of the UK’s energy production since the start of the industrial revolution is a real achievement.

This shows how the nation’s energy system is changing to embrace low-carbon electricity production through the use of nuclear, solar panels, wind turbines and a switch from coal to biomass and gas-powered stations.

In 2016, the government reported that it was working to phase out the last coal plants by 2025 in an effort to cut overall carbon emissions.

As we move towards low carbon power generation, renewable technologies such as air source heat pumps become even more viable and attractive.

So it looks like we are really starting to see a greening of the electricity grid which is tremendous news for renewable technologies such as heat pumps, which consume electricity but use it to maximise renewable heating for our homes.

Earlier this year, we produced an infographic looking at the history of home heating so I’m delighted to see that we are starting to enter the last phase of that and set the scene for a low-carbon power generating grid, feeding low-carbon heating systems – all of which will help minimise energy bills for homeowners and aid the country as we strive to meet stringent carbon reduction targets.

We look forward to discussing this more on The Hub over the next few years as we strive to move towards a truly zero-carbon society.

At Mitsubishi Electric, we also love to discuss this topic over on our Green Gateway Twitter page, so please join the conversation.

Russell Jones is PR & Communications Manager for Mitsubishi Electric Living Environment Systems in the UK.

H+H and SIG Offsite collaboration helps meet housing demand

Celcon Elements

In a unique collaboration, H+H UK Ltd and SIG Offsite have worked together to create the SIG I-House – an innovative housebuilding system incorporating Celcon Elements from H+H. 

The SIG I-House provides all the speed of offsite construction with the familiarity of a traditional build, from foundations to roof in just five days.

The system can encompass the inner leaves of external cavity walls, floors, lintel, cavity closers, insulation and roof trusses. With the inclusion of soffit and fascia, the system delivers the internal skin of a property, fully wrapped and ready for follow-on trades.

Created at a time when there is a demand to increase the volume of house building and when skilled workers are in short supply, the system is a one stop shop for clients – with a single contractor required to deliver the whole house shell.

The system is intended for the construction of domestic houses of up to two storey height, replacing the structure of the inner leaf of external cavity walls, separating walls and internal partitions with storey height Celcon Elements.

Installed by the SIG Offsite team, Celcon Elements are craned into place and fixed using H+H element mortar.  Timber I-Joist cassette floors are used in conjunction with the system to maintain the speed of build and roofs are either standard truss construction or the ‘Roofspace I-Roof’ – panelised roof system.  All components are raised into position by crane.

Celcon Elements are manufactured from the same intrinsic material as aircrete blocks and have the same performance advantages including excellent thermal performance with reduced heat loss at thermal bridges.

Latest Schöck BBA Certification raises the bar

Schöck Isokorb BBA Certification

The latest BBA Certification awarded to the Schöck Isokorb is the culmination of an unprecedented standard of assessment by the BBA.   It has resulted in a much more demanding new generation of Agrément Certificates for thermal break products and the emergence of a new ‘Leader Certificate’.   This new ‘Leader Certificate’ incorporates significantly more detailed content on structural stability and performance of the balcony connector.

The rigorous assessment by the BBA involved tests for structural stability, fatigue stresses and fire. As a result, the enhanced Certificate includes a full description and specification of each component. Specification of threaded steel bars to connect the system to steel balcony; limitation for deflection of the concrete slab and steel; the requirement for fatigue stresses due to different temperatures and for natural frequency of the external concrete slab and steel balconies; thermal bridging at the junction between the balcony and the wall. In addition, it covers behaviour in relation to fire.

The BBA’s Project Manager, Seyed Tajallifar, emphasises that: “All future Agrément Certificates of this sort will follow this format. The items covered in the Schöck Certificate will be included in any other balcony connector Certificate when they are due for Reissue.”

Chris Willett, MD at Schöck comments: “We have always welcomed our collaboration with the BBA, which dates back over several years. This new generation BBA Agrément Certificate takes a huge step in providing the highest level of assurance to the construction industry and we are certain that it will lead to further specifications of our product in the future”.
