\u200bCAN YOU ACHIEVE A LOW LCA \u2014 AND STILL BUILD WITH CONCRETE ELEMENTS?
The answer is yes. The new residential development N\u00e6rheden NH6, also known as Elmen, is now complete, the residents have moved in \u2014 and the result speaks for itself: 5.8 kg CO\u2082e\/m\u00b2\/year. The project is a benchmark for how concrete can continue to play a central role in construction in both 2027 and 2029.<\/p>\n
When FB Gruppen and Ingcon launched the project, the goal was ambitious: to achieve a low carbon footprint of 6.55 kg CO\u2082e\/m\u00b2\/year \u2014 well below the BR18 limit value. The path to achieving this involved a meticulous review of structures and material choices. Nothing was taken for granted.<\/p>\n
As director Anders Bidstrup from Ingcon put it:<\/p>\n
\u2014 Previously, I could \u2014 said with all due humility \u2014 dimension a house like this in my head. But here we threw out the standard solutions and CO\u2082-optimised everything.<\/p>\n
To achieve this goal, it was necessary to use a significantly greater proportion of lightweight concrete in the construction than would traditionally have been the case. This means that all facades and apartment dividing walls that are not balcony-bearing were made in lightweight concrete.<\/p>\n
\u2014 We have done this before, explained Anders Bidstrup. But in connection with NH6, the exercise has been to see how low a cement content we can achieve in lightweight concrete, and how low a cement content we can achieve in the concrete that needs to be balcony-bearing.<\/p>\n
As part of that process, CRH Concrete has therefore tested and trialled demoulding the concrete at various strengths, and has concluded that it is possible to use C20 concrete where C35 would previously have been chosen. In addition, both the concrete elements and the lightweight concrete elements are produced in low carbon concrete \u2014 which is now our standard.<\/p>\n
The development comprises 123 apartments across five storeys with a basement, and nine terraced houses over two floors. The structure follows a classic layout with a heavy backing wall, insulation and brick facade \u2014 but behind the brickwork lies a series of crucial optimisations:<\/p>\n
A significantly greater proportion of lightweight concrete elements than usual Reduced cement content in load-bearing structures Use of C20 concrete where C35 would previously have been chosen Production of all elements as low carbon concrete (formerly LCC), which is now standard<\/p>\n
The N\u00e6rheden NH6 project achieved an LCA result of 6.0 kg CO\u2082e\/m\u00b2\/year \u2014 equivalent to 5.8 kg CO\u2082e\/m\u00b2\/year using the new emission factors from 1 July 2025.<\/p>\n
It is not only the use of concrete that has been examined in detail. Every single element in the construction has been meticulously reviewed to identify CO\u2082 reductions.<\/p>\n
\u2014 The entire building has gone through a process where we said that what we normally do, we throw out. The exercise has then been CO\u2082 optimisation, says Anders Bidstrup.<\/p>\n
\u2014 We have done this in collaboration with CRH Concrete but also with all other parties. All materials have been selected on the basis that we wish to retain the traditional structure with a heavy backing wall, insulation and a brick facing wall. So we have made some CO\u2082-optimised choices whilst also optimising the process. We know which parameters we can adjust. And since we have worked together with FB Gruppen, AFRY, Sweco, CRH Concrete and several of the suppliers and subcontractors for many years, it has been easier for us to fine-tune the process.<\/p>\n
Anders Bidstrup continues: \u2014 In collaboration with the engineers from AFRY, we have tried to redistribute the forces throughout the building and investigate whether the construction can still withstand what it needs to. Previously, we had walls so strong at 18 cm and C35 that we could take a small facade section, calculate the transverse and longitudinal stability on that, and we were done.<\/p>\n
He elaborates: \u2014 Now we reduced the structures to 15 cm and added considerably more lightweight concrete. The entire exercise was about limiting the amount of concrete. In collaboration with the architects, FB Gruppen and Ingcon have also tried to position the windows more appropriately so that they do not affect the stability of the building. Some of the windows have been raised 50\u201380 cm above floor level, and there is a bottom plate and a top plate in the concrete, which means that the concrete element achieves greater strength. With regard to the balconies, heavier brackets are used so that the balconies meet the required standards, even though the concrete is less strong.<\/p>\n

Den \u00e6ndrede tilgang til projektet har betydet et l\u00e6ngere forl\u00f8b og en anderledes rytme i planl\u00e6gningsfasen. Ingcon A\/S<\/span> og FB Gruppen<\/span> har haft flere og tidligere m\u00f8der med de centrale samarbejdspartnere end normalt. R\u00e5dgiverne blev trukket ind p\u00e5 et tidligt tidspunkt, og dialogen med eksempelvis CRH Concrete har v\u00e6ret mere intensiv end i tidligere projekter.<\/p>\n If\u00f8lge Anders Bidstrup har det ogs\u00e5 \u00e6ndret fordelingen af ressourcer. En st\u00f8rre del af budgettet er flyttet over til r\u00e5dgiversiden, og selv om brugen af letbetonelementer har reduceret elementprisen, er projektet samlet set blevet dyrere p\u00e5 grund af de sk\u00e6rpede klimam\u00e5l.<\/p>\n Trods den \u00e6ndrede proces er der ikke eksperimenteret med nye eller upr\u00f8vede materialer \u2013 byggeriet er udf\u00f8rt med kendte l\u00f8sninger.<\/p>\n – Det er en solid etageejendom, vi bygger, Vi st\u00e5r jo ogs\u00e5 p\u00e5 m\u00e5l for en fem\u00e5rs gennemgang efterf\u00f8lgende, og vi kan godt lide, at vi i byggeprocessen har styr p\u00e5 vand og lugt og skimmel, forklarede Anders Bidstrup. – Med det klima vi har i Danmark, hvor det regner store dele af \u00e5ret, er det vigtigt med materialer, som kan t\u00e5le vand i byggeperioden, og n\u00e5r huset s\u00e5 er t\u00e6t, kommer de materialer, som er fugtf\u00f8lsomme.<\/p>\n [\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row column_structure=”1_2,1_2″ make_equal=”on” _builder_version=”4.27.4″ _module_preset=”default” background_enable_image=”off” global_colors_info=”{}”][et_pb_column type=”1_2″ _builder_version=”4.27.4″ _module_preset=”default” background_image=”https:\/\/crhdenmark.dk\/wp-content\/uploads\/2025\/10\/NH6-1-scaled.jpg” global_colors_info=”{}”][et_pb_image title_text=”Islands-Brygge_CRH-Concrete_aflang” disabled_on=”off|off|off” _builder_version=”4.27.4″ _module_preset=”default” global_colors_info=”{}”][\/et_pb_image][\/et_pb_column][et_pb_column type=”1_2″ _builder_version=”4.27.4″ _module_preset=”default” global_colors_info=”{}”][et_pb_text disabled_on=”off|off|off” _builder_version=”4.27.7″ _module_preset=”default” global_colors_info=”{}”]<\/p>\n The changed approach to the project has meant a longer process and a different rhythm in the planning phase. Ingcon A\/S and FB Gruppen have had more meetings \u2014 and earlier ones \u2014 with the key partners than is normally the case. Consultants were brought in at an early stage, and the dialogue with CRH Concrete, for example, has been more intensive than in previous projects.<\/p>\n According to Anders Bidstrup, this has also changed the distribution of resources. A larger proportion of the budget has shifted to the consultancy side, and although the use of lightweight concrete elements has reduced the element cost, the project has overall become more expensive as a result of the more stringent climate targets.<\/p>\n Despite the changed process, no new or untested materials have been used \u2014 the construction has been carried out using familiar solutions.<\/p>\n \u2014 It is a solid residential building that we are constructing. We are also accountable for a five-year review afterwards, and we like the fact that during the construction process we have control over water, odour and mould, explained Anders Bidstrup. \u2014 With the climate we have in Denmark, where it rains for a large part of the year, it is important to use materials that can withstand water during the construction period, and once the building is weathertight, the moisture-sensitive materials can be introduced.<\/p>\n [\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row disabled_on=”off|off|off” _builder_version=”4.16″ _module_preset=”default” global_colors_info=”{}”][et_pb_column type=”4_4″ _builder_version=”4.16″ _module_preset=”default” global_colors_info=”{}”][et_pb_text disabled_on=”off|off|off” _builder_version=”4.27.7″ global_colors_info=”{}”]<\/p>\n <\/p>\n N\u00e6rheden NH6 demonstrates that concrete is not an obstacle to DGNB \u2014 quite the contrary. With precise data from product EPDs and well-documented solutions, concrete can form part of DGNB-certified construction projects. The development has been pre-certified to DGNB Platinum (manual 2023) and meets the climate requirements expected in the building regulations for both 2027 and 2029.<\/p>\n DGNB is not only about one parameter \u2014 it is about the balance between environmental, economic and sociocultural quality. Here, concrete stands strong.<\/p>\n N\u00e6rheden NH6 also demonstrates the importance of using the right data. With product EPDs and precise documentation, the CO\u2082 level for concrete elements is made clear. This changes the picture when comparing with other materials and supports a genuine and accurate basis for decision-making.<\/p>\n The development is a good example of how early dialogue and close collaboration between client, contractor, consultant and supplier can lead to tangible results. By challenging standard solutions and choosing optimised concrete elements, it has been possible to push the carbon footprint of the construction significantly downwards \u2014 whilst at the same time ensuring a long-lasting structure.<\/p>\n Behind the attractive brickwork at Elmen in N\u00e6rheden lie the optimised solutions that together produced the impressive result of 5.8 kg CO\u2082e\/m\u00b2\/year. The development has been pre-certified with DGNB Platinum, manual 2023 (N\u00e6rheden 6 | Danish Green Building Council).<\/p>\n The project is a reference development that demonstrates how, using familiar materials and documented methods, it is possible to achieve results in relation to the expected climate requirements in the Building Regulations for both 2027 and 2029. It sends a clear signal: the DGNB-certified construction of the future can indeed be built with concrete. It is about using the material wisely, documenting performance and drawing on the experience that the construction industry has already built up.<\/p>\n _____________________________________________________<\/p>\n Client: FB Gruppen<\/a> Project facts: DGNB Platinum (manual 2023) \u2014 pre-certified<\/p>\n _____________________________________________________<\/p>\n [\/et_pb_text][et_pb_video src=”https:\/\/www.youtube.com\/watch?v=uO47dShTfjM” _builder_version=”4.21.0″ _module_preset=”default” global_colors_info=”{}”][\/et_pb_video][\/et_pb_column][\/et_pb_row][et_pb_row column_structure=”1_4,1_4,1_4,1_4″ disabled_on=”on|on|on” _builder_version=”4.16″ _module_preset=”default” disabled=”on” global_colors_info=”{}”][et_pb_column type=”1_4″ _builder_version=”4.16″ _module_preset=”default” global_colors_info=”{}”][et_pb_image src=”https:\/\/crhdenmark.dk\/wp-content\/uploads\/2023\/05\/Islands-Brygge_-25-Large.jpg” title_text=”Islands Brygge_ 25 (Large)” _builder_version=”4.21.0″ _module_preset=”default” global_colors_info=”{}”][\/et_pb_image][\/et_pb_column][et_pb_column type=”1_4″ _builder_version=”4.16″ _module_preset=”default” global_colors_info=”{}”][et_pb_image src=”https:\/\/crhdenmark.dk\/wp-content\/uploads\/2023\/05\/Islands-Brygge_-24-Large.jpg” title_text=”Islands Brygge_ 24 (Large)” _builder_version=”4.21.0″ _module_preset=”default” global_colors_info=”{}”][\/et_pb_image][\/et_pb_column][et_pb_column type=”1_4″ _builder_version=”4.16″ _module_preset=”default” global_colors_info=”{}”][et_pb_image src=”https:\/\/crhdenmark.dk\/wp-content\/uploads\/2023\/05\/Islands-Brygge_-19-Large.jpg” title_text=”Islands Brygge_ 19 (Large)” _builder_version=”4.21.0″ _module_preset=”default” global_colors_info=”{}”][\/et_pb_image][\/et_pb_column][et_pb_column type=”1_4″ _builder_version=”4.16″ _module_preset=”default” global_colors_info=”{}”][et_pb_image src=”https:\/\/crhdenmark.dk\/wp-content\/uploads\/2023\/05\/Islands-Brygge_-14-Large.jpg” title_text=”Islands Brygge_ 14 (Large)” _builder_version=”4.21.0″ _module_preset=”default” global_colors_info=”{}”][\/et_pb_image][\/et_pb_column][\/et_pb_row][et_pb_row column_structure=”1_2,1_2″ _builder_version=”4.16″ _module_preset=”default” global_colors_info=”{}”][et_pb_column type=”1_2″ _builder_version=”4.16″ _module_preset=”default” global_colors_info=”{}”][et_pb_image src=”https:\/\/crhdenmark.dk\/wp-content\/uploads\/2023\/05\/Islands-Brygge_-15-Large.jpg” title_text=”Islands Brygge_ 15 (Large)” disabled_on=”on|on|on” _builder_version=”4.21.0″ _module_preset=”default” disabled=”on” global_colors_info=”{}”][\/et_pb_image][\/et_pb_column][et_pb_column type=”1_2″ _builder_version=”4.16″ _module_preset=”default” global_colors_info=”{}”][et_pb_image src=”https:\/\/crhdenmark.dk\/wp-content\/uploads\/2023\/05\/Islands-Brygge_-7-Large.jpg” title_text=”Islands Brygge_ 7 (Large)” disabled_on=”on|on|on” _builder_version=”4.21.0″ _module_preset=”default” disabled=”on” global_colors_info=”{}”][\/et_pb_image][\/et_pb_column][\/et_pb_row][et_pb_row disabled_on=”on|on|on” _builder_version=”4.16″ _module_preset=”default” disabled=”on” global_colors_info=”{}”][et_pb_column type=”4_4″ _builder_version=”4.16″ _module_preset=”default” global_colors_info=”{}”][et_pb_text _builder_version=”4.19.2″ _module_preset=”default” global_colors_info=”{}”]<\/p>\n [\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row column_structure=”1_5,1_5,1_5,1_5,1_5″ disabled_on=”on|on|on” _builder_version=”4.16″ _module_preset=”default” disabled=”on” locked=”off” global_colors_info=”{}”][et_pb_column type=”1_5″ _builder_version=”4.16″ _module_preset=”default” global_colors_info=”{}”][et_pb_image src=”https:\/\/crhdenmark.dk\/wp-content\/uploads\/2022\/11\/EDP-forsider_2022-Danfoss-House-1.jpg” title_text=”EDP-forsider_2022-Danfoss-House” url=”https:\/\/crhdenmark.dk\/wp-content\/uploads\/2022\/11\/CRH_EPD_21066-2-Projekt-Vaegge-LCC-m.-FutCem-2021-data-copy.pdf” _builder_version=”4.18.0″ _module_preset=”default” global_colors_info=”{}”][\/et_pb_image][et_pb_text _builder_version=”4.18.0″ _module_preset=”default” global_colors_info=”{}”]<\/p>\n\u200b<\/h2>\n
