Our green credentials

Our green credentials

Forty-six per cent less energy. And only just started.

Thirty-one years of small choices, and a few big ones – adding up to a smaller footprint each year.

Since 2017

Half the energy. A fifth of the fossil fuel.

At Ghan House we take clean energy seriously – and we keep the numbers. We compare each year against 2017 because it’s a useful baseline: gas boilers running, kitchen on gas, oil pumping into the radiators round the clock. Most of that is gone. What remains is the laundry’s gas drier, and that’s next on the list.

If you’re interested in any of this – solar, the heat pumps, what we did and what we’d do differently – ask Paul. He’ll cheerfully bore you over a coffee.

Solar 2026

39 kilowatts of sunshine. A 36-kilowatt battery to bank it.

Installed on 15 May 2026. We expect the array to generate around 29,000 KW a year – roughly 28% of our annual electricity needs. Combined with the gas eradication and the oil reductions since 2017, total 2027 energy should come in at about 135,000 KW: a 54% drop on the 2017 baseline.

If you’re thinking about solar for your own place, talk to Morgan at Solar Smart on 1800 911 770 – we thoroughly recommend them. Tell them Paul at Ghan House sent you.

Where we’ve cut

Five rooms of the house, quietly retooled.

None of this is one big switch. Most of it is small, year-on-year – the kind of work that adds up.

Water

Rainwater from the roof feeds the pond automatically. Motion sensors on the urinals, taps, lights and fan. Power-pump showers – saved water gets reused. The whole 12 acres is monitored weekly for leaks (we’ve found a few).

Gas

Gas use is 8% of what it was. The kitchen is fully induction – 94% of energy goes into the pan, not the room. Garden wing heating is now air-source. Only the laundry’s gas drier remains, and that’s next.

Electricity

39 KW solar + 36 KW battery (May 2026). Two air-source heat pumps keep house and garden wing at a steady 21°C. Motion sensors on lights, fans and toilets. Two EV chargers at the garden bedrooms. Bar lighting: 60 W on full, was 600 W.

Waste

Composting all kitchen peelings. Milk and orange juice in glass bottles, returned to Muchgrange Farm – saves three sacks of plastic a week. Toiletries from the Handmade Soap Company in Slane, refillable. Old papers into the fires. Frylite collects oil and cooked food for fuel.

Behind the walls

100% pure Wicklow sheep-wool insulation in the attic. Feather-down duvets and pillows in natural Oeko-Tex 100 materials. Weekly meter readings for every utility (an app called Meter Readings – Graham Haley). Water meter monitored remotely by newater.ie.

What’s next

Where we’re heading.

The 2017 baseline is a long way back, but there’s still further to go. The list above is the next round of investment – most of it sketched out, some of it costed, all of it being thought about.

Come and stay

A small stay, a smaller footprint.

Booking direct supports the work. Same with dinner. Same with a voucher to take home – small things that quietly add up.
