MAINTAIN YOUR HOUSE WHEN THE WEATHER IS GOOD

External timer: Clean, let it dry and re-oil with Jupex 45 chineese oil.

Raw linseedoil, Jupex 45, wooden tar, Jupex varnish and pigment.

-External wood: Pressure-wash, let it dry completely, apply one of the oils with brown pigment to saturation-point. Advice: Mix in some wooden tar in the oil to make it smell like a real Viking longboat, this prevents black spots too. Not to be confused with tar from stone-coal, the wooden tar is light and runny, it is made from sap-rich pine. The modern grey look you get from mixing brown, black and white pigment in the oil.

-External doors: Sand it even with 220 paper. Apply oil to saturation point, this mean

s perhaps 5 times, add pigment to oil so it becomes almost like a paint, apply thin and wipe off until surface is perfect smooth and all small cracks are filled (Not too thick!)-Windows: Sand with 220 sandpaper, apply pigmented oil to
saturation + apply pigmented Jupex varnish. It is the exposure to sun that cause the aging of paint and varnish on the south side.

If you try to keep that wooden appearance, simply replace the paint (pigmented oil) with clear Jupex varnish. (should be lightly pigmented with the brown pigment)

House after the first week in December 2015

Hi Lars, When agreeing the contract I asked for all floors except all bathrooms and utility to the engineered pine and that is what you included. I am being strongly encouraged to tile the kitchen area around the island. This comes to about 9 sqm. Would this be a problem for you to reduce the flooring area in pine by this much? I assume that the wood flooring you included also includes finishing with oil? Gareth

Dear Gareth,
I don’t agree with tiles in the kitchen at all, I will try to explain our thinking:.

a) In places where you stand a lot, for example around the hob and sink, it is very bad to have hard tiles. In fact, it would be illegal for health reasons if it was a workplace. A bouncy mat is usually located where you stand, eg. in front of machines. This is even more important in a warm and clean house where you stand without shoes.

Kitchen from 1995 with Morkaskog oiled engineered pine floor in a Scandinavian Home. Cleaned with white-soap all this years and survived OK after bringing up 3 children.

b) Cleanliness-wise, it is a lot easier to clean the wooden floor than the a tiled floor, it is smooth and has no dirt-collecting grout recesses.

c) The most important reason to not have tiles in the kitchen is because of their conductive nature. This ceramic material is naturally cold to the touch compared to wood. This is because the heat energy is absorbed or “sucked” into the tile like with most conducive materials eg. metals. This would be OK if floor-heat is left on, however, if floor- heat is used under large tiled areas the house tends to overheat even in the winter. Contrary to common belief, it is better to have a wooden floor on top of the concrete, it evens out the heat given off, and adds to the thermal stability of the house. Keep in mind that there is almost a foot of insulation under the concrete. This is why we recommend to focus the floor-heat in the relatively small tiled wet-rooms and possibly inside the front door.

d) If you drop something on a tiled floor it breaks, if you drop something on a wooden floating floor it usually survives.

e) Wooden panels can be used for the walls in bathrooms in warm and ventilated houses. Not behind the shower of course, but for the rest of the room and even behind the bath tub it is OK. We are however always careful to waterproof the floor and walls in all wet-rooms. Our special seal-system is applied before the tiling and wood-panelling.

House in factory last week of November 2015

The German Passive House Institute require an air-tightness <0.6 exchanges/h, so 0.19 exchanges/h is considered very good. That said, we still focus more on the outer air-tightness. For real world heat-losses in windy climates, we consider this outer air-tightness more important than the inner air-tightness that can be measured with this blower door test.

Another funny fact is that since PHI in Darmstadt does not recognize Swedish test results of the REC Temovex Blue 4 HRV unit (92% efficiency in Sweden),we are handicapped by being forced to use poorer default value of 80%

CHEAP COMPACT LUXURY HOUSES / AFFORDABLE PASSIVE HOUSES

Yes, all this sounds great. It is possible to do. We have tried to do this since 1991. Just a few obstacles…. : Our Irish government, various state bodies and County Councils do their damndest to make it as difficult and expensive to build a compact house as they can.

Sometimes I wonder  if they know what they do when they make up endless new regulations on: heath & safety, fire & energy, certifications & approvals, the list goes on and on. Then these nincompoops change the rules back (sort of..-nobody knows) and pretend there was no damage done. (I think of the certified certifiers and new very expensive BCMS system, the internet based management system for planning that is still there) 

Compact is square, cheap to build and to heat.

Concept Hibernia 113 1200sqft passive 3br family home

Hibernia 113 1200 sq.ft passive 3-br family home

Yesterday I was reading about Galway city council creating costs of 7200€ for a family in Oranmore for simply digging a hole and connecting to the water-mains. This must be considered borderline criminal.

Our authorities, falsely called civil servants, certainly need to come off their high horses with endless demands on others while being almost comical in their incompetence (think Irish water and local roads for example)

Sketch curved roof single storey compact home

Compact houses of 1-2 bedrooms can be built very economically if the state backed off.

Accept the following facts:  The planning costs, connection-fees certifications and all other (un-necessary?) costs hit the small house relatively harder than a large house. A modest 40 m2 passive house can cost 2500 €/m2 when all is said and done. But a large luxury house of 300m2 could be built for as little as 1100€/m2.

Another example is our backwards ESB / electric regulators that forbids washing-machines in the bathroom so they end up in the kitchen in small dwellings. In most modern countries the washing-machine is located in a wet-room (i.e the bathroom in a small dwelling), with floor trap and tanked floor for safety against water-damage. Cheap installation with plumbing in one place.

The exorbitant costs of house-insurance in Ireland is the topic for another day, but it is related to un-necessary water-damages from poorly build bathrooms and washing-machines in the kitchen too.

A total floor-area of 370m2 (4000 sq ft) including garage makes this Hibernia quite large.

 

 

 

It is one of the most price-efficient houses that can be built. The price per m2 comes down dramatically when larger houses as this are built with a bulky shape.

It also gives extreme energy-performance thanks to the small surface area to floor-area ratio.

We were lucky with the weather for a few weeks to finish off most of the external work.

When the rain and wind howls around the corners in the west of Ireland It is great to work away in a dry, clean and warm house.

 

 

 

 

 

 

 

 

 

It is easy to reach very quality when all conditions are controlled.

All materials on site and good order.

This assures a quick and seamless procedure.

A customer designed Baltica 126 that is made a little wider, 8400mm instead of the standard 7800mm, and with 40 degree roof and the new high truss will be built in County Clare in November. The higher walls in these houses gives a little different appearance with more wall visible over the windows. Alu-zinc/ galvanized steel rain-gutters and no usage of poisonous lead gives good opportunities for rainwater-harvesting if desired.
