a dip in the Oresund Strait before sunset


the day after I took a walk along the western edge of Daniaparken in Bo01, I stumbled across a series of people jumping (or dipping) into the ocean.  when I arrived at a stepped stonework area that led directly into the ocean, I knew this was the place.  the water must be cold, but if they are doing it, I try it too.  I pedaled home as quickly as possible.  even me, a crazy person who is willing to jump in the cold waters of Sweden, knows that scary monsters inhabit the ocean after dark.

I returned with a backpack loaded with a towel and an ice cold 50 cl (500 ml) Swedish beer.  I leaned the bike against the concrete wall, stripped down to my suit, carefully removed my flippie floppies, and waded ankle deep onto the wooden platform.  I stood for quite some time, skeptical of the temperatural (yes, that is definitely a word) effect of the sea on my body.  finally, after courage came and went several times, I swan dived into the icy blue water...

nothing solves the world's problems like taking a dip in the ocean at sunset and drinking a cold beer.

sunset in Vastra Hamnen


as the sun began to dip lower in the sky, I made my way along Ribersborg beach, aiming back toward Vastra Hamnen.  I stopped several times along the way to admire the kite surfers.  or are they called wind surfers.  judging by the amount of wind along the Western Harbor, this must be a great place to surf, regardless of what it's called.
kitesurfing in Sweden
if you google kite surfing while in Sweden, "kitesurf Sweden" comes up second, behind only the wikipedia page.  clearly there is a lot of wind here, even if Malmo is not listed as one of the hotspots.
as the sun went down, I walked along the boardwalk at Daniaparken in Vastra Hamnen on the edge of Bo01.  the weather was mild, maybe 64 degrees and the wind was not fierce.  as I walked along the boardwalk I saw many people eating bread and cheese, drinking wine, and sitting atop the wooden planks on the water's edge.

I passed by wooden steps leading down into the ocean and admired the platform, complete with a ladder into (or out of) the ocean.  the waves calmly lapped over the metal grating and splashed softly against the lowest steps of the wooden descent.

I continued along the boulevard, admiring the quantity of people who were enjoying the setting sun, the mild air, and the light breeze.  it tasted like a perfect combination of summer and fall, neither too hot nor too cold.  people were sitting out at the restaurants, sipping wine and eating dinner.

I passed by the corner building of Bo01 that houses Salt Och Brygga, a well known eatery anchoring the restaurants along the waterfront's western edge.

one of the most notable buildings in Bo01 is the building that houses Salt och Brygga (salt and bridge), a well known restaurant marking the corner of the first phase of Vastra Hamnen, easily picked out in photographs due to the giant wall of solar thermal "panels" on the southwest corner of the building 
this building is known for two things besides the restaurant: 1. it is the least energy efficient building in Bo01 according to post occupancy studies.  2. it has a giant vertical solar thermal array that ended up being slightly under efficient because its evacuated tubes partially shade themselves.

as I continued north along the water's edge, I stopped to capture the sun as it dropped lower in the sky and highlighted the Oresund Bridge.

food scraps = energy in Malmo: the food grinder


it's 6.30pm and you just arrived home from work.  it's time to make dinner.  it is a simple meal.  pasta with veggies and sauce.  you pull out the cutting board and your favorite knife.  you scrub all of the terrible pesticides and toxins off your vegetables, hoping that this shiny red pepper is not the one that puts one nano gram too much of whatever you don't want in your body.  you chop and cut and chop and suddenly you are sauteing it all in a pan.  the water is boiling for the pasta and voila! you have dinner.  it's delicious, by the way.

cleanup in this kitchen is almost as easy as making the mess.  you finished the pasta sauce so you splash some water around in the jar and dump it down the drain.  you open the door under the sink and deposit the jar into the clear glass recycling bin.  the scraps of vegetables go into the food grinder (what we used to call the garbage disposal).  you splash a little water on the plates and silverware and put it all in the dishwasher.  you always win the clean plate award so there are no scraps on the plate, but if there were any scraps or anything else that could be ground in the food grinder, you'd dump them into the sink and wash them "away" as well.
food grinder in kitchen sink
kitchen sink in the apartment.  pretty "normal" looking.  the silver button on the upper left turns on the food grinder.
then the magic starts.  you turn on the water and press the little silver button.  a loud gurgling sound emits from inside the sink drain, gradually getting more uniform and higher pitched.  when the last of the food remnants are gone, you press the silver button again and it's done.  your "wasted" food is on it's way to becoming energy.
food grinder in kitchen sink
it's a titan.  food grinder.
a separate piping system takes the water and ground food waste to a nearby storage tank.  it's surprisingly simple.  sedimentation allows the liquid to skim off the top inside the tank and join the rest of the waste water on it's way to a treatment plant in the harbor.  what settles at the bottom of the tank is pumped away to a nearby plant where they tank it all back together in a specific method that turns this "waste" into something called biogas.
separate pipes under sink collect food waste and water
pipes from both sink drains joining to go separately out of the building to a sediment and storage tank where the food waste separates and is pumped offsite for transformation from food waste to biogas
biogas, as you can imagine, is just like other gases that you know.  it can be burned like natural gas to heat your home boiler or hot water.  it can be refined into fuel to power your car.  it is basically like oil except we didn't have to dig for it or destroy anything like forests or water supplies or the environment to get it.  it is a natural byproduct of human consumption.  oh, and in case you are wondering (which I am sure you are) it is:
  • "clean" (meaning that the stuff that goes into the food grinder is food, not plastic or other undesirable items that dilute or destroy the biogas process)
  • hygienic for the inhabitant (what you put into the grinder is what you have already touched)
  • natural (no cleaning products, chemicals, or other stuff needs to be added)
  • simple (press a button and it's done)
  • cleaner burning (biogas is much lower emission and cleaner burning than many other fuels, especially oil based fuels such as gasoline and diesel)
if you are looking for an alternative to oil to power cars, buses, and other transportation, biogas could be a very successful option.  we've all seen how much food goes down the drain (which is, in itself, an area that needs some improvement).  the city of Malmo is making great strides to use food waste to produce energy and hopes to have the entire city bus fleet on biogas within ten years.  there is also a campaign to collect compost style food waste in all neighborhoods of the city as well as using the new grinder method.

want more info?
a company called vasyd is a main stakeholder in this process.  their (vasyd) website is also very informative (and has english translations).  I met with Mimmi Bissmont from the vasyd Malmo office.  she was extremely helpful and supportive.  thanks Mimmi!  her work focuses on connecting action, behavior, and sustainable efforts.  for more info on improved use of energy through behavior, check out this post on the psychology of energy reduction or this post about energy reduction through feedback loops.

the washer and dryer... I figured it out!

the bathroom in this apartment has baffled me since day one and I am still trying to figure some parts of it out, but each day it makes a little more sense.  the building is "passive" which basically means that there is no heating or cooling in the apartment.  there is a thermostat that you can turn up and it will simply supply you with clean air that has been pre (or re) heated by the heat produced by building inhabitants.  there are no air conditioners, no radiators, no nothing.  just these little things on the wall that spit out clean air and other ones that suck away the dirty air.  more on that as I figure it out.

front load washer and dryer

meanwhile, I figured out the washer dryer situation.  the washer is a pretty normal eco front loader, but the dryer had been baffling me for a couple of days.  I had been talking with Tamara about how to use the dryer and she explained that after every use you need to open up a little compartment on the bottom to wring out a filter and empty a little water compartment.

bottom of dryer
we both agreed that the system adds a little extra work each time you run the dryer and that it was a little annoying.  I could not explain why you'd need to empty water out of the dryer because clearly the washer has a drain so the dryer could too.

fan, filter and water compartment visible after opening front panel at bottom of dryer
after opening the front panel at the bottom of the dryer you can see where the fan operates (on the right) and where the filter can be removed (on the left) as well as the water compartment (bottom)
then it hit me.  its so simple I don't know why I didn't figure it out immediately.  you need to wring out the filter and empty the water compartment because there is no vent for the dryer.  whatever water is taken from the air inside the dryer has to go somewhere, so they suck it through a filter and deposit it into a compartment at the bottom.  because the apartment is passive and the heat created by the inhabitants is reused, they don't want to waste all of that heat venting outside so they vent inside.  in fact, the bathroom actually heats up during the dryer cycle because it is venting into the room!

so simple.  or so complicated?

tub not sealed to the wall...?


dear people (who have stumbled across this blog and mistakenly started reading it, only to find out that I don't use capital letters at the beginning of sentences and I talk mostly about food and beer instead of sustainable design and architecture),

can anyone explain this one to me?  the tub, which stands on four legs but has sides so it looks like a tub set onto (or into) the tiling, is not, in any way, sealed to the wall on either of the two sides that touch up against the tile.  the hot and cold pipes come up between the tub and the tile on the short side, in plain sight, touchable (and conceivably hotter than you'd want to accidentally touch).  when one is taking a shower, water bounces off the body, off the walls, and off the curtain and falls behind the tub on two sides onto the tile floor.

this defies all seventeen years of BAC education.  water is the enemy.  water is violent and dangerous and should be locked up, caged, or otherwise incarcerated.  water is the ruination of all architecture (even Falling Water).  right?

because water is clearly the enemy, we should always seal, finish, control, and ultimately ship water the hell out of anything we build, right?  doesn't water create mold and promote wildlife and destroy the ozone layer?  was I sleeping all through school?  somebody, please explain these pictures.

thanks!
me
shower and tub
the tub does not touch the wall on either of the two sides where it could and there is a huge gap where the pipes come up on the short side
corner of tub where tile should (maybe) meet the tub
here's the corner.  you can see a large gap and a small gap and water droplets just relaxing there (because I am taking their picture).  as soon as I leave the room and turn off the light they drift down to the floor...
water collecting under the tub
see, here is the water under the tub on the floor.  that white things is one of the four feet for the tub.
drain for the tub
yes, this is the drain for the tub.  a hole in the tile floor with a pvc pipe going through it.  yes, since you asked, there is water building up all around the hole and I am pretty sure some falls down there to... somewhere.  no I did not test for mold.  I am just assuming that there is mold forming in there somewhere...
