By Søren Dietz  In 2020, Denmark decided to create 75,000 hectares of new forest. Biomass willbe needed for district heat­ing in the future, as approx­i­mately two-thirds of Denmark’s district heat­ing is currently supplied by biomass from forests. The construction indus­try is increas­ingly switch­ing to bio-based build­ing mate­ri­als. Atthe same time, nature in Denmark is under enormous

I 2020 beslut­tede Danmark at skabe 75.000 hektar nyt skovareal. Biomasse vil være nødvendigt til fjern­varme i fremti­den, da cirka to tred­jedele af Danmarks fjern­varme i øjeb­likket leveres af biomasse fra skove. Byggein­dus­trien omstiller i stigende grad til biobaserede bygge­ma­te­ri­aler. Samtidig er naturen i Danmark under enormt pres: over halvde­len af ​​arterne er uddøde eller truede.

Rapporten er en slutrap­port for projek­tets første plan­lægn­ing, etab­ler­ing og organ­is­er­ing. I tråd medfor­målet for puljen kan rapporten bruges som inspi­ra­tionsek­sem­pel for samme type projek­ter, dergennem­føres med henblik: udvikling og anven­delse af løsninger, der omfat­ter produk­tion, lever­ing, forbrug,deling af elek­tricitet, varme eller køling, aggregering, energi­la­gring, flek­si­­bilitets- og energi­ef­fek­tivitet. Projek­tet er inspir­eret af solcelle overdækkede parkeringsarealer

By Søren Dietz  In Denmark 2/3 of build­ing heat is District heat­ing. The polit­i­cal aim is to reduce CO2emissions by 70% in 2030 with 1990 as refer­ence. Build­ings make up for 40% of the CO2 emis­sions – so reduc­ing green house gas from build­ing play a major role. Green­house gas reduc­tion may come from both saving energy

In Denmark, it has been polit­i­cally decided to reduce emis­sions from all sectors by 70% until 2030. This paper looks at whether reno­va­tion of typi­cal houses can make a contri­bu­tion to reduc­ing CO2 emis­sions based on measured values and compares measured values with
calcu­lated values over a measured period over 5 years (2016–2021).

Passiv Solar design basics, a cross­ways for low emis­sion build­ings? Danish Build­ing Regu­la­tion allows a market that chooses non-compact and none-passive Solar opti­mized design. 

How can Denmark achieve climate goals, in a sustain­able way, with Bio District heat­ing with less Biomass – is more build­ing insu­la­tion the answer?

In this Paper LCA calcu­la­tions are done by using LCAbyg based on 2 differ­ent mate­r­ial data to analyse how this can influ­ence total emis­sion results. The data used are: 1) the generic mate­r­ial data and 2) by using EPD mate­r­ial prod­uct data.

This analyse looks into how to balance energy saving and energy effec­tiv­ity to reach 2030 70% reduc­tion — and 2050 emis­sion neutral targets. Embod­ied Carbon in insu­la­tion is a smaller part of a energy effi­cient buildings.

Climate change – is cool­ing needed?
Climate change means higher middle temper­a­tures also in Denmark, esp. in late spring and summer. As people expe­ri­ence higher temper­a­tures there is a grow­ing need for user friendly summer comfort design.
