One of Europe’s key climate breakthroughs came in the form of the EU’s nearly zero energy building target, as Dr. Marc Ó Riain explains in the latest part of his series on the history of low energy building.

Plans for over 33,000 net zero carbon new homes are underway across the UK, Passive House Plus can reveal.

Heat pumps rise, PV falls and fabric stands still.

It sounds like an impossibility: a high density, architectural, zero energy home on the tightest of back garden sites, adaptable to the needs of everyone from empty nesters to a family of six without opening a toolbox. But sometimes a project comes along that redefines what is possible.

High efficiency is a hugely important factor in choosing a heating system and this is a key priority for industry leading manufacturer Grant, whose wide portfolio of heating technologies has advanced over the years and now includes air source heat pumps, underfloor heating, pre-plumbed hot water cylinders, aluminium radiators and fan convector radiators.

NI still plans to tighten energy rules for new build

A rundown 1970s scheme of one-bedroom, single storey social housing units in Ballyshannon, Co Donegal, has been transformed into a pioneering development of cosy, A-rated, NZEB-busting homes. The pioneering project – the first completed under Ireland’s deep retrofit pilot scheme – also breathed new life into an unloved green area and is expected to help fuel a regeneration project in the town.

The health, comfort and monetary benefits of building to the nearly zero energy building (NZEB) standard offers an opportunity to help convince Irish people of the benefits of climate action, housing minister Eoghan Murphy has said.

A luxury new development in an exclusive Dublin location will achieve nearly zero energy building (NZEB) standards with help from Daikin Altherma air-to-water heat pumps and a highly energy efficient building fabric.

A new research project at UCD will aim to uncover key early lessons from the design and operation of nearly zero energy buildings (NZEBs) in Ireland. The NZEB standard will become mandatory in Ireland for dwellings from November.

Concerns have been raised that proposed changes to Irish building regulations — designed to bring Ireland in line with EU requirements that new homes be ‘nearly zero energy buildings’ (nZEBs) from the end of 2020 — could encourage sub-standard approaches to ventilation and airtightness.

The Passive House Institute has announcd the launch of its two new certification categories, Passive House Plus and Passive House Premium, which recognise on-site renewable energy generation. 

Nearly a third of construction professionals did not know about the nearly-zero energy requirement for all new buildings by the year 2020, according to a survey of Passive House Plus readers.
