this sold snap began last weekend we have a decent amount of
snowfall 3 -4 inches which has been lying since Sunday night,
when i took the pictures attached over an hour ago the outside
temp was 0 C, the inside temp was 18.5 C with no stove lighting.
When we put the stove lighting the temp in the living area goes
to 21 - 22 C (24 C if we put a lot of timber in) and the temp
for the remaining downstairs is approx 20 C (bar my office which
is north facing, has a door to the outside and is always 2 -3
C lower than rest of house). The upstairs temp is consistently
17 - 19C morning/nightime.
On the performance of the house i have to say we are very
pleased thus far. At the outset i should point out that
the house was built to A1 standard - Thermohouse ICF envelope
including Thermohouse roof system, passive standard triple
glazed windows and doors throughout, Heat recovery ventilation
system and we also have a double sided 12 KW stove in
our main living area.
To underline the performance of the house since we moved
in April we have no other space heating requirement bar
the stove throughout the whole house. When this is mentioned
to people they find it very hard to beleive but it is
a fact and we are living proof.
i was asked what attributes most to the performance of the
house i would say the thermohouse roofing system. If you look
at pics of the roof (bar south facing) you will see that the
snow is continuing to stay on the roof as the heat is being
retained by the thermoroof. In a conventional roof the snow
would have melted due to heat loss. I would also have to say
that getting the sealing mechanism and avoidance of cold bridging
in your windows and doors is another critical component in
We moved into the house on 18th January 2011.The carpenter was
concerned about movement on the timber floor for two reasons.
Firstly the size of the open plan living area was quite large
and secondly the house was only newly built. Having tested the
moisture content he was surprised at the low readings. It meant
that fitting of flooring and doors went ahead quite quickly
and there have been no problems since.
is a gas boiler and under floor heating installed which has
not been used since we moved in.
We found that the solid fuel stove with a back boiler has
been sufficient to heat the house and hot water during the
winter months. We stopped using the solid fuel stove in early
April. The solar panels have continued to heat sufficient
hot water for daily use since then.
house is fitted with a heat-recovery-ventilation system, which
is in daily use. It keeps the house fresh and free from odours.
It means that our open plan living area is odour free despite
the fact that the kitchen is part of that living area. A little
dog has recently joined our family. Her bed is in the utility
room and she is in the process of being house trained but
the house is still odour free.
husband suffers from hay fever and my son suffers from asthma.
We all find that the quality of our sleep has improved a lot
since we moved in. My son previously had disturbed sleep because
of a blocked nose and gradually we found that he needed less
inhalers as well. My husband was taking hay fever medication
in March 2010 but this year he never used it.
attic space is much larger than we had expected because of
the ICF roof panels. During the sub-zero temperatures in January
we began to use the space as an area for drying clothes. By
installing an extra outlet and inlet from the HRV system it
has prevented a build up of moisture in that space. Our tumble
dryer became obsolete even in the winter! Even in the wet
areas, towels which are used and left hanging on shower doors
are dried out by the next day.
rented a small cottage of some 500 square feet while the construction
was in progress. ESB bills for that cottage averaged 160 euros
per 2-monthly bills. We estimate the bills on this 2000 square
feet building to be in the region of 150 euros.
find living in an ICF house to be a very pleasant experience
and we're very grateful to our engineer for recommending ICF
and HRV. We didn't know what to expect but it has all turned
out very well.

Weve been really enjoying the cold snap in our new house
with temperatures staying fairly constant, only going in one
direction upwards, when the tumble drier is on! The house
has been very comfortable, and we have been happily watching
the frost accumulate on the outer pane of the triple glazed
windows. The roof has been covered in frost (unless defrosted
by the sun) for a while now, so were pretty happy that
theres no loss of any heat through the structure itself
or any of the windows. The only problem is trying to get dressed
for the outside conditions, because looking out the window from
the comfort of a constant 20 degrees, its just impossible
to imagine any kind of cold!
very happy that we opted for ICF, and were looking forward
to many more winters where the investment continues to pay

It is performing very well, we are easily maintaining temperatures
of 18-20oC in all the rooms internally.
We have a 15Kw oil boiler which is only cycling on and off(
periodically) to keep the temperature up in the buffer tank
mostly during the late evening and early morning for DHW.I
have not had a chance to do an air blower test yet but am happy
with the performance of the house to date pending outcome of
