No blowing our house down! Polyurethane exterior wall insulation to the rescue

Here we are again with an update on the Polyurethanes Passive House. With the cold winter weather sweeping across Europe, we figured it was time to put up the exterior wall insulation. Watch the video below to see the installation of our polyurethane panels:

The external walls are made from brick work blocks. The cavity between the external wall and the supporting wall was filled with 180mm polyurethane boards; our polyurethane insulation panels are keymark certified and optimise thermal insulation with the low lambda value of 0.023 W/mK. In total, the walls will be 450mm thick, providing our future residents with an external wall U-value of 0.10/0.11 W/m2K. What does this mean? Limiting U-values in the UK are 0.70 for external walls, that’s a U-value 7 times less! In other words, in our Polyurethanes Passive House you’ll be cosier and have more money in your pocket due to a lower energy bill.

We’ll follow soon with more updates on the house; for now please follow our Twitter account, @polyurethanes4U and enjoy other videos on our YouTube account: PolyurethanesMedia!

What lies beneath?

One doesn’t often think of Antarctica as a hive of activity. However, its isolation provides an opportunity for scientific research uninterrupted by human expansion; this week it was the centre of some ground-breaking research (pun intended!). Lake Vostok is one of the largest freshwater lakes in the world, but what makes it unique is its sheer inaccessibility – it lies 4,000 metres beneath the central ice sheet of Antarctica, untouched by life for more than 15 million years! Russian scientists have been drilling down to the lake’s surface for more than 14 years and last week they finally reached their destination. In case you didn’t know, and before we continue, Antarctica is the home of over 100 research centres from dozens of countries due to its vast opportunities for discovery.

What’s to discover in the ice you ask? Check out this picture: it shows a three-inch long shrimp-like creature, known as a Lyssianasid amphipod, found 600 feet beneath the West Antarctic ice sheet and 12.5 miles from open water. Scientists have argued that the extremely high levels of oxygen and nitrogen found in many of the lakes are toxic for most life forms – the water in Lake Vostok, for example, has a consistency similar to a fizzy drink! Nevertheless, multicellular organisms including the Lyssianasid amphipod call the ice-sheets home. The resilience of such microbial life forms has made scientists hopeful that ancient bacteria could have evolved to cope with the frozen, black conditions under the ice-sheet.

Another on-going research mission is the British expedition to Lake Ellsworth, which lies 3,000 metres under the West Antarctic ice sheet. The continent’s isolated nature, purity, and weather conditions (the coldest temperature ever recorded on Earth was minus 89° Celsius at Vostok) pose specific challenges for recovering samples. The expedition at Lake Ellsworth is therefore using “space-industry standard clean technology” to collect liquid water samples, including sterilised polyurethane bellows. The sterilised technology allows the researchers to enter the lake without danger of contaminating either the lake or the samples. Kevin Saw, who heads the NOC National Oceanography Centre (NOC) design team for the Ellsworth project explained the benefits of using polyurethanes:

“The NOC selected polyurethane as the best candidate material for the bellows, as not only did it meet the temperature and performance requirements, it could also be clear. “This was not 100% necessary but if you are doing something that hasn’t been tried before in an extreme environment it’s good to be able to see what’s going on.””

The 5m long polyurethane bellows remain flexible down to -30° Celsius and can withstand exposure to hydrogen peroxide vapour (which scientists use to keep it sterile). Using the bellows provides a sterile environment to house the water collection tubes, and to allow for effective measures of salinity, temperature, pressure, oxygen levels and pH balance of the ice sheet and lake.

UK PassivHaus schools point the way to a brighter, healthier, energy-saving future

The PassivHaus concept is increasingly becoming part of mainstream building techniques. Less familiar however, even to sustainability aficionados, are PassivHaus schools. PassivHaus schools over the last few years have gained popular standing in Europe: over 25 schools have been built in Germany and Austria, whilst a recent initiative in Flanders, Belgium, will require every new school built to be PassivHaus certified. The past week marks a momentous step forward for PassivHaus schools with three schools, Oakmeadow and Bushbury Primary Schools in Wolverhampton and Montgomery Primary School in Exeter, becoming the first certified PassivHaus schools in the UK.

Jonathan Hines, Director of Architype which designed the two Wolverhampton schools, emphasises simplicity and quality in his buildings rather than “overcomplicated technical solutions”. Noting the “tough inner city” atmosphere of the Wolverhampton area, he focused not on creating rigidly standardised environs, but rather adaptable spaces capable of catering to a variety of student activities, whilst also creating “calm, uplifting environments”.

Oakmeadow’s new students celebrating the opening of their new school.

One of the most interesting aspects of the build, carried out by Thomas Vale Construction, was that Wolverhampton Council approved the project only under the condition that the cost would equal that of a traditional school building. Not only was this promise delivered on, the low energy use of the buildings means that the schools will face significantly reduced utility costs; according to Architype, the cost of the energy lost in a traditional school due to poor insulation standards compared to the airtightness found in PassivHaus schools is more than £5,000 per year! Additionally, the air quality found in a PassivHaus design is significantly better than in traditional schools; the fresher air makes for healthier, more attentive students.

A third school, Montgomery Primary School in Exeter, was also certified this week. The school will cater to 420 pupils and includes a nursery. Its design focused on high quality insulation and air tightness; the architects placed an emphasis on long-term sustainability by designing their building “to not only pass current requirements but to meet the demands of predicted future climate to 2080”.

Schools, however, aren’t the only large-scale buildings whose energy-use is receiving attention from Councils eager to cut energy bills. In December, the Mayville Community Centre received PassivHaus certification. This building was a tough challenge; located in Islington, one of the more deprived areas of London, the centre was a local authority-owned Victorian building built circa 1890. Prior to renovation the building was described as “uninsulated, inefficiently used and inaccessible”.

The above images from bere:architects show Mayville Community Centre post-retrofit (left), with Newington Green Primary School, (right) which has not been substantially renovated since it was built in 1958. The yellow and orange spaces indicate heat lost through lack of effective insulation. Bere:architects and Buxton Building Contractors Ltd ensured that the retrofit was of a sufficiently high energy standard to achieve PassivHaus certification, while also creating a useable space to serve the needs of local residents. As the first certified PassivHaus non-domestic retrofit in the UK, the Community Centre received the 2011 3R Award (Refurb, Rethink, Retrofit) for Best Public Building.

ISOPA congratulates the teams who contributed to these innovative and impressive designs! We hope they will inspire a new generation of sustainable schools, insulated with polyurethane of course!

What leeway does the Danish Presidency of the EU Council have on energy efficiency?

On 1 January 2012, the Danish presidency of the European Union Council began, for 6 crucial months. Denmark’s Prime Minister, the elegant Helle Thorning-Schmidt (below), presented the presidency’s program to the European Parliament during last week’s plenary session (video of the speech).

Is it necessary to remind that Denmark takes over the EU Council presidency at a time of great uncertainty, with one absolute priority, coordinating the way out of the Eurozone crisis? Is it also necessary to “rub it in”, so-to speak, and say that every other Danish priority will be overcast by the Eurozone crisis?

 

The irony of the Danish position is that their presidency comes at the crossroads for the EU on the way to the EU 2020 Strategy objectives, with upcoming discussions on the Multi-Annual Financial Framework (MFF) for 2014-2020.

The EU has committed to increase its energy efficiency by 20% by 2020, but is only on track to meet half of this objective; 8 years to the deadline, it will take a lot of political will to succeed. It is therefore vitally important that Denmark manages to move the talks forward on the Energy Efficiency Directive, to try and reach a first reading agreement with the European Parliament. On the other hand, financing is a key hurdle in energy efficiency talks and Europe will probably have to be very creative on energy efficiency financing during the MFF 2014-2020 talks (via the Future Cohesion Policy, the Horizon 2020 Programme, and potentially the pilot EU project bonds), otherwise the EU will simply miss the target.

There was a sigh of relief from proponents of energy efficiency at the end of the Polish presidency, Poland who usually does not lose too much sleep when the energy efficiency agenda is stalling, and who therefore focused primarily on energy infrastructure. Despite the context, Denmark should be a different story, and at least the (cautious) commitment is there on paper: “The presidency will engage in a targeted effort to secure the adoption of initiatives for promoting energy efficiency, where the energy efficiency directive will be a key priority.” Read the Danish Presidency programme

But just how much room for manoeuver do they have?

Not much, for the Council is committed to block any measure they will deem having budgetary impact in the Energy Efficiency Directive (see latest Council draft), thus jeopardizing a first reading agreement on the directive. Negotiations will be tough on the energy efficiency directive, therefore Denmark will try to create room for maneuver by tying them to the Energy 2050 Roadmap in the presidency’s program.

The other thorny issue for the Danish presidency will be the financing of energy efficiency investments. Here again, it seems plausible that Denmark will seek an agreement that will secure both investments from the private sector and the earmarking of EU funds towards achieving the 20% energy savings target. As for provisions which aim at forcing Member States to earmark funds for energy efficiency, they don’t really stand a chance, even more so in the current context.

With empty government coffers and a lot of sensitivity in the Council, Denmark’s approach seems to be to work on securing a solid framework and a long-term path for investors. In our view this means that the Presidency will attempt to 1) coordinate talks between the Energy Efficiency Directive and the 2050 roadmap (cf. Euractiv’s point last month); 2) try to bargain for binding targets with the argument that it will secure long-term private sector investment in energy efficiency technologies whilst allowing Member States to adopt specific measures; 3) drop the binding 3% renovation rate for public buildings for a commitment to address renovation of existing buildings in a separate piece of legislation.

Will the Danish presidency manage to secure a deal on the Energy Efficiency Directive? They are managing expectations but certainly haven’t turned their backs on the idea; now let’s see what the Council’s mood is in the New Year!

The Energy Efficiency Directive on a Tightrope

Bird on a Tight rope

Our last post on the European debate on the energy efficiency directive dates back from 1st December 2011. Back then, we concluded that no clear picture had so far emerged in the European Parliament. Although progress has definitely been made behind the scenes, thepicture remains blurry and the prospects for a significant directive to emerge are bleak, very bleak.

The key: a divided European People’s Party (EPP)

In the complex sequence of events, since last December 1st, confusion has grown especially within the European People’s Party (EPP), the largest group in the European Parliament, without which a strong Parliament position will not be possible. MEPs in the Parliament’s Environment committee adopted an amendment to the directive that is to see carbon prices go up in order to avoid a further slump in carbon prices. The reasoning is that if carbon prices go down, investment in low-carbon technologies is neither incentivized nor rewarded.

Interestingly, the Environment committee’s amendment on carbon prices could replicate the feud that took place between DG Environment and DG Energy in the final stages of negotiation before the European Commission proposal was published. This time it is not Connie Hedegaard (Climate Action Commissioner) against Günther Öttinger (Energy Commission), but Peter Liese (EPP-Germany ENVI committee opinion rapporteur on the EED) against Markus Pieper (EPP-Germany ITRE committee shadow rapporteur).

The two EPP parliamentarians epitomize the gap within the EPP on energy efficiency, that the centre-right group’s leaders are currenlty working on bridging behind the scenes. This is very important indeed because Claude Turmes (Green – Luxemburg), the Parliament’s rapporteur on the directive, needs a large majority in order to prevent the Council from nipping the directive in the bud, which it has clearly vowed to do (see Euractiv’s well-informed article last week).

Open questions on the politics behind the Energy Efficiency Directive

One question is whether the rapporteur can do without the minority of EPP members (34 out of 263 that is 13%) who voted against the Bendtsen report last year on the Energy Efficiency Action Plan. Another question is the relative power of some EPP members hostile to the energy efficiency agenda in the ITRE committee, mainly Markus Pieper (shadow rapporteur), Herbert Reul (Chair of the ITRE committee) and Cristina Guttierez-Cortines (substitute in ITRE but active in the committee’s discussions). The last question is closely linked to the other 2 and relates to the general context of sustained economic crisis in many European countries, and how it affects the behaviour of EPP MEPs who mostly belong to parties currently in power in their Member States.

Claude Turmes is walking on a tightrope, because faced with vehement opposition in the Council, he cannot afford going to the negotiation table without a clear and unambiguous mandate from his institution. As he put it in a committee meeting the other day “if I’m going to play a game of strip poker with the Council, I want to make sure I don’t show up naked”.

A decisive month ahead

The discussions going on behind the scenes in the next fortnight will be vitally important, to find compromises on the thorniest issues on the Energy Efficiency directive: the legally binding nature of the 20% energy savings target, the legally binding 3% renovation target for public buildings, the scope of the energy savings obligation scheme for utilities and of course the issue of financing. The timetable laid out by Turmes is tight, since it aims at reaching an agreement on compromise amendments by 21 February 2012, for a vote of the report in the Parliament’s industry committee on 28 February 2012.

Polyurethane innovation means sky’s the limit for wind power industry

The power of wind is remarkable; throughout history it has pushed the sails of explorers seeking what lies beyond the horizon. Today, the wind still blows our sails toward a better future as we harness its sustainable power to charge our iPods, laptops and, in the near future, vehicles.

Wind power is destined to be an important contributor in realising the pressing demands for green energy in Europe. The European Union has set a binding target of 20 per cent of its energy supply to come from renewable sources by 2020; in order to achieve this target, more than one-third of European electrical demand will have to come from renewables. Wind power is expected to deliver 14-18 per cent of demand; delivering on these targets relies on the ever improving standards for efficiency and reliability of wind power. One of the current challenges is the weight of turbine blades, which can necessitate large wind farms to produce sufficient power. According to the European Wind Energy Association (EWEA), new lighter blades will have the benefit of being “easier to transport, and of course tackling heavy loading at higher tower heights.” While it is currently possible to generate substantial levels of wind energy at times, new, lighter blades will assist in creating more reliable levels of power throughout the year.

Research teams including the University of Case Western, chemical company Bayer and the Molded Fiber Glass Research Company have been racing to develop wind turbine blades, like those above, which utilise the unique advantages of polyurethane. Previously, glass reinforced polyurethane composites have been used for products including agricultural equipment, heavy-duty construction equipment and watercraft. These recent innovations have adapted this polyurethane material to the specific requirements of wind turbines. The prototype blades have proven in preliminary tests to be eight times more durable, tougher and substantially lighter than conventional models such as epoxy or vinyl ester blades. The “results of mechanical testing for the carbon nanotube reinforced polyurethane show that this material outperforms currently used resins for wind blades applications,” according to Ica Manas-Zloczower, Professor of Macromolecular Science and Engineering at Case Western.

What does this all mean, you ask? The lighter, stiffer blades enabled by the usage of polyurethane allow us to maximise energy production as it permits the construction of larger wind turbines. As the blades also improve on levels of fatigue and fracture toughness, it ensures the blades ability to withstand the stress of high winds. These bigger, stronger blades in turn capture greater amounts of wind energy compared to traditional turbines. According to EWEA, “the blades should [also] be economically feasible, using sustainable materials”; the polyurethane prototype produced by BAYER contains “low, or no, volatile organic compounds (VOCs) and use sustainable raw materials from renewable resources”. Studies on the prototype have shown that the technology “can even be “retrofitted into existing designs at minimal cost”.

The world’s total wind electricity capacity grew 50 times in the period 1990-2007 and predictions are increases over the 2008 level of 10-fold by 2030 and 20-fold by 2050. In 2009 the EU produced 163 TWh of wind power; this meant 106 million tons less of CO2, the equivalent to taking 25% of cars in the EU off the road and enough to power 82 million electric cars! Progress in the industry will inevitably be a combination of research in a variety of technical areas; polyurethane, however, provides a valuable contribution in optimising wind power technology. With the introduction of these next generation polyurethane blades the sky could be the limit for the wind energy production, the EU and you.

Happy Holidays with Polyurethanes!

Christmas – the magical day that every child (and all of us who still want to be children!) looks forward to every year. We all have our little rituals at Christmas time, whether it’s unpacking your stocking in front of the fire or curling up by a brightly decorated tree. A great Christmas, however, is going to need some preparation and a great way to get into the festive spirit is by making Christmas decorations. The easiest decorations to start out with are salt dough ornaments like these:

 

Salt dough ornaments can be made into any shape you like, from stars to snow men, and can easily be painted or decorated with icing. If you string them together they even make a great substitute for tinsel! They’re also a perfect Christmas activity for young children; let them pick their own shapes and write their names onto the decoration.

 

 

Coat the ornaments in a few thin layers of polyurethane to protect them and you can enjoy them (and embarrass your children) for years to come. Katy Elliott’s blog has a recipe and some creative ideas for ornaments like those pictured above.

 

Another homemade ornament is a seashell tree decoration (very Martha Stewart). With gold or silver paint, some glitter, ribbons and of course a layer of polyurethane to really bring out the colours, they’ll look right at home on any Christmas tree.

 

 

If you’d like something more creative than a traditional holly wreath hanging on your door this Christmas, candy cane wreaths are a colourful modern option that will also last a lot longer than holly. Simply stick the candy canes to a solid base and then spray with a layer of polyurethane to keep those sticky fingers at bay!

 

 

As always there are more adventurous options. Check out this impressive homemade model train Christmas village made with expanded polyurethane:

If, however, you’re more inclined towards putting your feet up to watch Miracle on 34th Street or the Muppets Christmas Carol, there’s still hope for creating a Winter Wonderland in your home. After all, what Christmas would be complete without a (polyurethane) snowglobe? And maybe if you’ve really been good this year, Santa will bring you an iPad and polyurethane cover!

 

Happy Holidays from the Polyurethanes team!

We’ve done it! We’ve “topped out” the polyurethane Passive House!

Crack open the bubbly, or juice box depending on your age and preference! We’ve “topped out” the polyurethane Passive House! As announced in our earlier blog, the roof was installed on 25 November. The video, which is up on our YouTube account PolyurethanesMedia along with other interesting clips, can be enjoyed below; expect additional videos, pictures and commentary from those involved on the Polyurethane Passive House website and here on the blog!
