NZEB

Nearly Zero Energy Building

Why  NZEB

NZEB means Nearly Zero Energy Building and is the current building regulation standard in Ireland as of the 1/11/2019

Nearly Zero Energy Buildings means a building that uses very little energy, resulting in lower carbon emissions for the environment and lower energy bills for the homeowner. The nearly zero level of energy required needs to include renewable sources such as solar/wind/wood and can include energy from renewable sources produced on-site or nearby.

Building to this standard means that you will have an airtight, well insulated home, orientated to maximise the benefit from solar gain (heat from the sun).

Requirements for Domestic & Non Domestic Buildings

Domestic Buildings

For all new builds, there will be a 25% improvement in energy performance on the 2011 Building Regulations. This will help eliminate fuel poverty and ensure that homes are warm, dry and environmentally sustainable.

Non Domestic Buildings

For all new builds, an equivalent to a 60% improvement in energy performance on the 2008 Building Regulations is required. This means there will be an improved energy performance for the building envelope, services and lighting requirements. There is also a compulsory requirement for renewable sources. The renewable sources must contribute to 20% of the main energy use, however there is some flexibility if the building is a higher specification than building regulations. This typically produces an A3 Building Energy Rating or higher.

This standard of building can be achieved with minimal additional cost when compared to traditional masonry building. A major barrier to success in this standard is choosing a main contractor who understand this process and can deliver a house to this standard.

Pat Doran Construction has been building to this standard since 2013.

In addition, we have successfully completed 9 certified Passive Houses resulting in super low energy-efficient homes.
