NEARLY ZERO ENERGY BUILDINGS
NZEB In Simple Terms
NZEB (enn-zeb) is the new standard of energy-efficient building in Ireland and a major BUZZWORD. But there are important changes that people going into the building process need to know about. And these changes also apply to HOME REFURBISHMENTS and EXTENSIONS!
As we all know there are big problems with climate change these days and this is why NZEB has come about. But in reality, it's only good news for the homeowner as with NZEB come BIG improvements in building quality and value for money.
NZEB (should, when done right) will ensure excellent comfort in our homes, high-quality construction, considerably lower energy bills, healthier living spaces and increased home value... the benefits go on.
In Ceardean we have been moving towards these standards for some years so many of our clients have already benefited from our progressive approach to energy-efficient design. However, as always we will continue to learn and improve upon this aspect of design and aim to exceed these new standards and look far into the future with our home designs.
The Big Myth: Optimal energy performance does not immediately mean more expensive design or building. But it does mean smarter design, more attentive building, better use of products and increased awareness of how we use our homes.
What NZEB means for:
Cost To Build: As New Irish Houses Have Been Constructed Near NZEB Standards For Some Years Now, New Homes Should NOT Cost You Much More After These Changes In Building Regulations.
Benefits To New Homeowner
