3daysofdesign - eelgrass panels from Søuld

 

Søuld have developed and now produce building materials made from eelgrass ... an abundant, renewable and locally harvested sea plant.

Eelgrass has been used for centuries for thatching homes and farm buildings in some coastal regions of Denmark and for the exhibition at the Sabsay Gallery Store in Strandstræde there was a demonstration of the technique by a master thatcher.

The panels that Søuld make replace synthetic materials with a natural material that holds carbon that can absorbs toxins in the air but also absorbs moisture to balance the climate in the room. Salt, naturally found  in the eelgrass, deters insects.

For the exhibition, the architect David Thulstrup, produced tables and plinths and room screens that are made from the panels combined with glass and steel in a collection called MOMENTUM.

Bygningspræmiering / Copenhagen Building Awards 2021

Bygningspræmiering -The Copenhagen Building Award - was established in 1903 and, each year, is granted to buildings that have made an outstanding contributed to the 'physical framework' of the city and reflect the importance of good architecture in the life of the city.

It is important that these buildings reflect the special character of of the city and contribute to the quality of its built environment.

For the building awards there are four categories:

A: nybyggeri / new building
B: omdannelse / restoration
C: renovation of apartments in a building that had another purpose
D: bymiljø / urban environment

For 2021, the Committee assessing the award: 

Culture and Leisure Committee
Nicolai Bo Andersen and Rosa Siri Lund, experts appointed by the Academic Architects' Association
Lisa Sørensen, expert appointed by IDA / Ingeniørforeningen Danmark
Camilla van Deurs, City Architect, Technical and Environmental Administration
Mette Haugaard Jeppesen, architect, Technical and Environmental Administration

Here are the buildings and engineering projects that have been short listed for the award in 2021 and they show just how diverse the built environment of the city is and all would be more than worthy winners.

Until 20 April, the public can vote for a public winner through the web site of the City Kommune and the overall winners of Building Awards will be announced on 27 April 2021

Life Without Energy

This project from SPACE10 was undertaken with the Indian design lab Quicksand. They visited 40 families in Kenya, Peru, Indonesia and India to look at how little or no access to electricity restricts or controls day-to-day life and limits opportunities.

With limited incomes, several families who were interviewed spent available money on improving or constructing a more secure and solid home - above any priority for electricity - but then used power, often solar power, first for charging mobile phones as that gave them access, for the first time, to banking and to ways of selling their produce at more competitive rates.

Lighting for safety or security and for extending the working day is important and it was interesting to see that some preferred to continue with traditional forms of cooking on open fires rather than buying stoves that can be expensive and unreliable. It was not just that fridges and electric stoves could be expensive to repair but the supply of electricity could be intermittent or unreliable or family income could be unpredictable so some form of backup like kerosene was kept for when the family could not pay for electricity.

Here, in the exhibition, there are photographs from the project with extended captions that set out the difficult choices that many people have to make when they do not have access to reliable or affordable or safe energy.

Life Without Energy: Needs, Dreams and Aspirations - is the report that came out of the research project and it can be read on line.

note:

In the World there are around 2 billion people with restricted access to electricity and of those there are as many as 860 million people with no access to electric power of any form.

Access to affordable, reliable and sustainable energy is one of the UN Sustainable Development Goals for 2030 along with efforts to improve sanitation, nutrition and access to safe water.

Carbon footprint calculators for citizens

Recently, I received an annual summary from the company that supplies electricity to my apartment. Apparently, my usage is "average" but I realised that I had no idea what that means or if it is good or bad. People can be average smokers but that still does not mean smoking is good for them

Here the meters are read remotely and payment is paid by my bank to the company automatically so it could not be easier and then electricity is one of those things I really don't understand. And that's even though I was relatively good at physics at school. I've got a literal sort of mind that likes to see cause and effect so, even now, I can't get my head around alternating current that, by simply its name, implies something that ebbs and flows. A pump can be switched to alternate … can suck or blow but if the water I use did the same then it would surely fill and then empty the sink!

I digress. What I really mean is that I can’t see or judge, in anything like real time, how much power I'm using and, in terms of my personal carbon footprint and my impact on global warming, that can't be good. Most people act only when they see the impact of what they do in real time.

So, out of interest, I looked on line and came across an article …. Carbon footprint calculators for citizens, Recommendations and implications in the Nordic Context by Marja Salo and Maija K. Mattinen that they published in 2017.

It does not provide the solution but does look at some of the problems in making this sort of interface easy to use and meaningful but also raises questions about how, in an age drowning in information, and, even in Scandinavian countries where there is probably a higher perception of the problems of global warming, it is still difficult to find out what we should do and what impact that will have.

In the first apartment I rented in Copenhagen, I was the first occupant in the place after it had been created in the attic space of a building well over a hundred years old and the owners pointed out just how much they had had to spend to comply with current standards for insulation but then I experienced the gains first hand when the first winter came. Despite being in the roof and despite large dormer windows and one large room with floor to ceiling windows onto a balcony, I did not turn on the radiators …. and that was despite the fact that it was on the community heating system so it would have been too easy to turn it on with no physical feed back of boilers going on and off that I'm used to.

In the second apartment, it was in a very large housing complex and monitoring electricity and heating use was outsourced through a heating consultant. He came one day to do an annual check with the figures for my power usage and said he wanted to check thermostats on radiators because I seemed to be consuming more than would be expected but that was resolved when I pointed out that it was a large and very open apartment and writing and doing research meant the apartment was occupied during the day and I was sitting at a desk in a large space with floor to ceiling windows in an apartment that was nearly twenty years old so not built to current standards and heating had to be kept relatively high or I'd have to sit at the computer wearing a scarf and gloves.

I'm suspicious of monitors and assessments offered by the utility supplier or the manufacturer of white goods because surely they just need to sell me more and, on the other hand, a generic and vague tick-box survey cannot, surely, take into account things like working from home and yet we really do need more guidance and more tangible proof that relates to us specifically if we are to change habits and make a difference.

climate change and rising sea levels

 
 
 

If there is a sudden rain storm In Copenhagen and, within an hour, streets are flooded and businesses are closed and transport is disrupted, then the consequences from climate change seem obvious and imminent. Problems are here and are now so, for politicians, planners, voters and tax payers, the need to act and act now is easy to understand.

But rising sea levels are more difficult.

For a start, the time scale is longer. People still talk about dealing with once-in-a-hundred-year storms … perversely trying to persuade themselves that means it will not happen for a hundred years when a catastrophic storm tomorrow could still, strictly, be once in a hundred years if it's then 99 years until the next one.

Statistics and the data seem much less certain for the rise in sea levels but how can we expect scientists to be any more precise with predictions when these changes are on such an enormous scale and there are so many variables - not least when it comes to calculating a tipping point as sea ice or glaciers melt?

But for Denmark, these calculations and planning now for works for mitigation are crucial.

On one side of the weighing scales, for policy makers and planners, are some positives: Denmark is a relatively small and relatively prosperous country with a strong history of major and successful engineering projects and with a population that still appreciates and understands the role of the state in major interventions for general gains. But, on the other side of those scales, Denmark is a low-lying country with an astonishing number of islands and a coast line that, as a consequence, is said to be about 7,300 kilometres in length. Is it a case of too much to do and too little time?

 
 

Living now on Nyhavn I'm very aware of the levels of the water in the harbour as the tide rises and falls each day. It might not be as dramatic or by as much as on the west coast - where settlements face out to the North Sea and its weather - but still the level of the water in the harbour rises by as much as a metre from the lowest to the highest level through each day. There is a fixed measure on the bridge across the middle of the harbour that I can see from my desk … or, to be completely honest, there is a height marker I can see from my desk if I stand up …. and I can also hear when the tour boats stop just before the bridge to drop off and pick up passengers if the tide is too high for the boats to get under the bridge to reach the ticket office and landing stage at the top of the harbour.

The quayside here is just 1.5 metres above the level of the sea water at high tide …. so, to put it the other way round, the sea is just 1.5 metres below my front door.

The highest tidal surge out in the sound - sea water driven by winds or storms - was apparently three metres in 1872 although there seems to be no record of floods and damage in the city that year as a consequence. Complete official records date back only to 1890.

There was a surge of 1.57 metres in 1921 and the highest surge of sea water from a storm recently was on 19 January 2007 when the water level rose by 1.31 metres. I've looked at back copies of Politken for that weekend but, curiously, there seem to be no reports of flooding or damage in the city with just one report about the harbour that weekend that has a photograph of a huge number of bikes that had been hoiked out of the canal around Christiansborg as part of a clean-up campaign.

But then add the height of a possible storm surge to the higher level of the sea because of global warming and melting of polar and Greenland ice and you can see why the city has to make major decisions now about what has to be done.

Calculations have suggested that, between now and 2050, sea level in the sound will rise between 10 centimetres and 30 centimetres and by the end of the century - so only 80 years away - the rise in sea level here will be between 20 centimetres and 1.6 metres with a 5% chance the rise will be over 2 metres. The median figure for the rise in sea level for Copenhagen is 70 centimetres and that could mean water lapping over the quay at high tide.

The only thing that is certain, is that I won't be here eighty years from now but, in a worst-case scenario, the sea will be at the front door of this building and that is without worrying about storms.

The whole of Christianshavn was built up out of the sea in the 17th century and looking at historic maps it is clear that the outer part of Nyhavn was built out way beyond the line of the beach.

I have read somewhere that the crown sold off areas of the sea bed and it was up to new owners to drive in wooden piles and fill in and create a plot for their buildings. Whether or not that is true, I wonder how much rising water levels will effect foundations. There is remarkably little visual evidence for subsidence but what will happen as the water table rises? And, more important, whatever work is considered to protect the city from flooding, major engineering interventions will change, and change permanently, the character of the inner harbour and the beaches and low-lying land of Amager - the island immediately to the south of the city.

 


 

Special Report on the Ocean and Cryosphere in a Changing Climate.

Last year - in September 2019 - the Intergovernmental Panel on Climate Change published their Special Report on the Ocean and Cryosphere in a Changing Climate.

Produced by more than 100 climate and marine scientists from 36 countries, this report assesses how global warming is having an impact on sea levels as sea ice melts and uses clear research data to calculate the potential extent of change and the rate of change.

Through the 20th century, sea levels rose by 15 centimetres (6 inches) but as global warming is causing ice in glaciers and in the Arctic and Antarctic sea to melt at twice that rate then calculations indicate that by the end of the century, so by 2100, sea levels will rise by an additional 10 centimetres so between 61 centimetres and 1.1 metres and if the Arctic ice sheets melt faster than current predictions suggest, then, by 2100, sea levels could rise by 2 metres.

Small glaciers are expected to lose more than 80% of current ice mass and that would have a severe impact on supplies of drinking water and consistent supplies of water to rivers for irrigation. With flooding of coastal areas and the impact on coastal cities and on densely populated delta areas then changes to sea level will dramatically reshape "all aspects of society."
