founded the company in 1959
Henning Larsen Architects
employs 200 people
from 20 different nations
65% of turnover derives from
international projects

11. Starting point
“Sustainability is an opportunity
for all architects to bring more
meaning and value into our lives
and society”

12. Method and tools: Reduce – Optimize - Produce
“During the past year, Henning Larsen
Architects has designed more than half a
million m² with an energy consumption
of 40 kWh/m2/y
– a reduction of 15 million kWh (BR10)”

13. Projects by Henning Larsen Architects – low-energy
Campus Roskilde, Denmark Nordea HQ, Denmark
44 kWh/m²/year 18 kWh/m²/år
Moesgaard Museum, Denmark University of Southern Denmark
43 kWh/m²/year 42 kWh/m²/year

14. Siemens HQ, Munich Viborg Town Hall, Denmark
46 kWh/m²/year 44 kWh/m²/year
Spiegel HQ, Hamburg King Abdullah Financial District,
80 kWh/m²/year Saudi Arabia
HafenCity Gold Medal Under construction: World’s
largest LEED certified city district

15. Tools co-developed by Henning Larsen Architects

16. Existing building stock
European trends
- No money – but investments are needed
- More for less – added value
- How do we compare? Measurability and performance
- Complexity increases - the tenders get to detailed
- How should we work? Data + knowledge = better buildings
- Why are we slow? Toolbox is full of techqnologies – but everybody asks for add
value

17. Existing building stock
– Planning strategy and m²
”Complete renovation increases the total building value.”

18. Existing building stock
Our approach
- Research and development
- Partnerships
- Spatial and technical strategies
- Always looking for winwinwinwinwin…….

19. Software – special calculator for money and energy

22. Case: A desk top analysis on a port folio

23. Different analysis:
Energy savings in % in
relation to money
invested/m2
Buildings marked in red has
the largest potential

24. There are strategies
Light Medium Heavy

25. Case: LIGHT
www.energimål.dk - Building is technically optimised

26. Case: MEDIUM
Existing tower is expanded with 1,900 low energy m². (minus 25% in kWh/m2/y)

27. Case: HEAVY
New low energy twin tower + 6,000 m². (minus 40% in kWh/m2/y)

28. Test af strategy on city level
”Do we want to develop our cities?”

29. Case: LIGHT
Implemented at city scale

30. Case: HEAVY
Implemented at city scale

31. Existing building stock
– Daylight used as design measure

32. Knowledge: Energy-efficient design
Geometry and location
are important aspects of
low-energy building

33. Knowledge: Energy-efficient design

34. Knowledge: Energy-efficient design

35. Knowledge: Energy-efficient design

36. Case: Daylight renovation, Denmark 2011-12

37. Research – PhD

38. Case: Daylight renovation, Denmark 2011-12
Replacing existing
windows with French
windows (two layers)
25 % less energy
30 % more daylight
38

39. Case: Daylight renovation, Denmark 2011-12
+ 10-15 % more sun on the facades
+ 15-20 % more sun at ground level
+ 20 % more m²
+ More quality in outdoor spaces and green spots
