Domestic construction regulations for energy conservation have changed considerably in recent years and DTW are happy to comply with the new regulations. DTW are determined to ensure that all buildings constructed meet or surpass the existing regulations. Domestic Houses now require a 60% improvement in Energy efficiency from that required in 2007.
Houses must now comply with near Zero energy requirements. These requirements have added about 5% to upfront construction costs, however the running costs of newly constructed houses is far less than houses constructed even just 5 years ago, and indeed the costs will be recouped in less than 5 years.
DTW recognised the need for an Irish model of the passive house (in concrete block). By bringing together our accumulated Irish, Swedish and German knowledge, skills and technology we are now creating Super Homes which can be lived in with almost no running cost.
Passive Houses are highly insulated, comfortable, cold bridge free structures that require little heating, they usually have triple glazed windows, heat recovery ventilation (HRV) and high air-tightness levels. Passive House using our construction methods costs only about 5% more than a standard build construction, as money saved on a complex heating system pays for better windows or extra insulation. Combining Passive House principles with Solar heating reduces the heat demand of a Passive House by 90%.
DTW are happy to guide you thru this design process and ensure you get the maximum return for your money and a cosy home.

The Irish Green Building Council advise investors and developers to act now to ensure that all new commercial developments are Near Zero Energy before new regulations make it mandatory.

The Irish Green Building Council advise investors and developers to act now to ensure that all new commercial developments are Near Zero Energy before new regulations make it mandatory. Group warns that just complying with the current energy efficiency regulations for commercial property is not good enough anymore.
To mark European Sustainability week, beginning Monday 23rd June, the Irish Green Building Council is advising all developers not to wait, to ensure that all new developments are Near Zero Energy. A European directive requires that from the 31st December 2018 public bodies can only acquire new buildings that are Near Zero Energy. By the 31st December 2020 a second revision of the standards to comply with the Near Zero Energy Buildings requirements will come into force. These Near Zero Energy Building standards will be expected to meet a 60% improvement over current standards.
Speaking on the regulations, Pat Barry Executive Director of the Irish Green Building Council said:” We urge all developers not to wait for the new standards to come into place. Good developers already go well beyond current standards. Mere compliance with current regulations is no longer good practice and carries an asset value risk for any new construction offered for sale or letting after 31st December 2018.“
In contrast, regulations for residential construction have already reached the near zero standard since 2011, meaning that new dwellings built in 2014 should be much more energy efficient than those built in the Celtic tiger period. Unfortunately regulations for commercial buildings still lag far behind.
Commenting on the initiative to raise awareness of the new standards, Michael Donohoe, Director of Corporate Services with Colliers International noted that “a proactive approach now to designing and developing commercial office space to meet the new standards not only ensures a pipeline of space that will satisfy the increasing demands of global corporations establishing or expanding in Ireland, but also future proofs and strengthens the long term property asset values.
Mr. Barry concluded: “Given the long lead in time for new development, there should be a sense of urgency to design and build to improved standards right now. Anything at design stage now will only be reaching in completion in 2018. If it is not at the Near Zero standard it in 2018 it excludes not only the public sector as potential tenants but probably also a large proportion of the foreign direct investors. Foreign direct investors are driving demand for sustainable construction as they generally have higher standards than native tenants.”
