Herning, Denmark
Tietgensgade - Ecology pays back in lowering rents
 |
 |
This project is situated in the southern part of the city of Herning, which over a period of 10-15 years is to be converted from an old industrial area into a pleasant residential area using general ecological approaches for the construction and operation of buildings.
FællesBo has constructed a youth residential complex, which functions as a demonstration project showing the way for environmentally sound building approaches. The project consists of two similar blocks, one conventional (Block A) and one “green” (Block B), in order to evaluate and compare the cost/benefit of each choice of environmental measure installed in the two blocks. There are a total of 84 apartments, 3300 m2 floor area and approx. 120 tenants. Furthermore there is a basement area of 370 m2 with a laundry room, assembly hall, engineering room, and two study-rooms.
Numerous low energy elements are implemented in the “green” block, such as extensive insulation, solar collectors, electricity saving measures, and an all-over energy management system. Monitoring was initiated almost immediately after the completion in September 1999. Still when it comes to innovation, the ventilation with heat recovery and passive solar energy stands out as the most salient part of the construction project.
- Ventilation with heat recovery and passive solar energy
- Combined solar collector and low-temperature district heating for floor heating and domestic hot water
- Reuse of collected rainwater for toilet flushing
Monitoring Scheme:
| Building period: | Work started: August 1998 | |||
| Work finised: August 1999 | ||||
| Monitoring period: | September 1999 - December 2000 | |||
| Monitoring results: | 42 “green” dwellings (Block B) with a total floor area of
1699 m2 42 conventional dwellings (Block A) with a total floor area of 1699 m2 |

| Heat: (kWh/m2) |

| Electricity: (kWh/m2) |

| Water: (m3/m2) |
1,1 | 0,84 | 0,68 | |
| Other Results/ archievements | In 2000 consumption data have been collected
for both blocks. These data show: • Heat consumption for room heating in the green block is 26% lower compared to the conventional block. • The consumption of tap water is 26% lower in the green block. • The heat consumption for domestic hot water per m3 is 52% lower in the green block. Additionel monitoring during a 7 weeks period from 12.2-3.4.2001 confirms that there is on a minor increase in electricity consumption (1,7%) in Block B compaired to Block B. |
