Dette er et så utrolig godt prosjekt at jeg valgte å skrive om og oversette deler av det som sto TU. Dett er et prosjekt som det er bra å skryte av til utenlandske aktører.Energi effektiviteten er fantastisk ved disse tiltakene og det er viktig at kommunen (og andre offentlige aktører) går foran å benytter ny teknologi. Innovative innkjøp hvor løsninger på energi og klimaspørsmålet er målet og hvor en etterspør funksjon og ikke produkt er viktig for utvikling i denne bransjen. Asker kommune er i dette prosjektet et godt eksempel.
Her er min engelske versjon og link til oppslaget i TU idag.
Asker municipality will build Norway's most energy-efficient Indoor Swimming hall
With 15 energy wells and 650 sqm solar becomes the swimming hall in Asker will become Norway’s most energy-efficient swimming hall and save millions in energy costs annually.
Holmen swimming hall in Asker municipality will be one of the first pure passive swimming halls.
Vidar Nyhus, who is responsible for the project from the municipality of Asker say that by means of two heat pumps there shall be collected energy from 15 mining wells for heating the swimming facility. Three other heat pumps will recover energy from the ventilation system to the air, pool and tap water. - That way we can utilize evaporation heat from the pool, says Nyhus.
For reducing ventilation requirements due to evaporation of water, it shall also be installed vertically adjustable bottom in several of the pools.
- By raising the bottom of these pools at night, the evaporation is reduced. It is thus less work for the ventilation system when pools are not in use, explains Kenneth Olafsen, project manager for the municipality.
However, the measures dos not end there. A heat pump ensures namely to recover heat from the water that goes down the drains when bathers use shower facilities.
The energy wells allows for free cooling and reduces the cooling load of the building. A solar plant under the parking lot, which recharges energy wells in the summer, heats them and helps snowmelt in winter, explains Olafsen.
The swimming hall's energy needs are estimated at 1.6 million kWh per year.
In addition 650 m2 solar cells will be installed solar the roof and facades that and will produce electricity to the swimming pool. This should provide a current production of around 73,000 kWh annually. This will cover about 12 percent of the annual electricity consumption of the hall, explaining Nyhus.
