The energy grid of Raksila sports centre will halve the carbon emissions from buildings<\/h1>\n
Last year, an energy vision was prepared for Raksila Sports Centre in Oulu. The energy grid made up by the ice hall, swimming hall and Oulu Hall, all owned by the City of Oulu, will reduce the area\u2019s carbon emissions by half and save up to 200,000 euros each year.<\/strong><\/section>\n

\n<\/strong>Oulu is involved in the Energy Wise Cities project, which seeks local means of reducing carbon emissions. Raksila Sports Centre has the largest potential for this. \u201cThe ice and swimming halls are the two City facilities that consume the most energy,\u201d says the City of Oulu\u2019s energy specialist\u00a0Johanna M\u00e4kel\u00e4<\/strong>. When the third City-owned facility, Oulu Hall, is counted in, the buildings consume as much energy as 10 residential blocks. \u201cThe energy-saving measures taken in Raksila have a huge impact on the City\u2019s climate goals.\u201d<\/section>\n
The swimming hall and ice hall are a perfect match<\/strong><\/p>\n

The energy vision for Raksila, devised by Sweco, shows how the buildings\u2019 energy flows can be circulated around the area. One of the options is directing the ice hall\u2019s condensation heat into the district heating network. \u201cHowever, this solution proved more financially challenging than the other options,\u201d says\u00a0Timo Heikkil\u00e4<\/strong>, Sweco\u2019s specialist in sustainable and smart construction.<\/p>\n

On the other hand, a heating and cooling grid shared by the three buildings worked like a dream. \u201cThe ice hall and the swimming hall are a perfect match, since one needs constant cooling while the other needs heating,\u201d Heikkil\u00e4 says. With heat pump technology, the condensation heat from the ice hall warms up the swimming hall for most of the year, and even Oulu Hall gets its share of the heating.<\/p>\n

Up to 90 per cent savings in delivered energy<\/strong><\/p>\n

The three-building energy grid saves up to 90 per cent of purchased and delivered thermal energy. For the swimming hall, this means annual savings of 120,000 euros, and for the entire area, 200,000 euros. The condensation heat produces almost seven gigawatt-hours of energy, thanks to which only one gigawatt-hour of district heating is needed. \u201cThis way, the energy grid reduces the buildings\u2019 carbon footprint by half,\u201d Heikkil\u00e4 says.<\/p>\n

It was crucial for the City\u2019s decision-making that the pay-off period of the energy grid\u2019s implementation is only six years. \u201cAll measures suggested in the vision have already been implemented and included in the project plan for the renovation of Raksila swimming hall. We are also planning to use the solution model in other swimming halls in Oulu,\u201d M\u00e4kel\u00e4 says.<\/p>\n

Potential for many cities and municipalities<\/strong><\/p>\n

The Raksila energy vision has gained immense interest in Finnish cities and interest organisations. \u201cThe results have positively surprised many municipalities,\u201d M\u00e4kel\u00e4 says.<\/p>\n

Heikkil\u00e4 sees the City of Oulu as a pioneer, but other cities also show potential in areas where a single operator owns multiple properties. \u201cIn many cases, one building needs heating and another needs cooling, so this point of view should be expanded from an individual plot to the block level.\u201d<\/p>\n

Usually, area-specific energy analyses do not face challenges with technology or lack of knowledge, but with the ownership of the buildings. \u201cContract-wise, it\u2019s much more complicated to plan an entity with multiple property owners,\u201d Heikkil\u00e4 says. \u201cThen again, energy grids provide opportunities for cooperation and synergy benefits, even between multiple operators.\u201d<\/p>\n<\/section>\n\t\t<\/div>\n\t<\/div>\n<\/div>\n<\/section>\n","protected":false},"excerpt":{"rendered":"","protected":false},"author":42,"featured_media":6802,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"_seopress_robots_primary_cat":"none","_seopress_titles_title":"The energy grid of Raksila sports centre halves emissions ","_seopress_titles_desc":"The energy grid made up by the ice hall, swimming hall and Oulu Hall, all owned by the City of Oulu, will reduce the area\u2019s carbon emissions by half.","_seopress_robots_index":"","footnotes":""},"categories":[139],"tags":[],"class_list":["post-14572","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-news"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.sweco.fi\/en\/wp-json\/wp\/v2\/posts\/14572","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.sweco.fi\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.sweco.fi\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.sweco.fi\/en\/wp-json\/wp\/v2\/users\/42"}],"replies":[{"embeddable":true,"href":"https:\/\/www.sweco.fi\/en\/wp-json\/wp\/v2\/comments?post=14572"}],"version-history":[{"count":8,"href":"https:\/\/www.sweco.fi\/en\/wp-json\/wp\/v2\/posts\/14572\/revisions"}],"predecessor-version":[{"id":38450,"href":"https:\/\/www.sweco.fi\/en\/wp-json\/wp\/v2\/posts\/14572\/revisions\/38450"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.sweco.fi\/en\/wp-json\/wp\/v2\/media\/6802"}],"wp:attachment":[{"href":"https:\/\/www.sweco.fi\/en\/wp-json\/wp\/v2\/media?parent=14572"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.sweco.fi\/en\/wp-json\/wp\/v2\/categories?post=14572"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.sweco.fi\/en\/wp-json\/wp\/v2\/tags?post=14572"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
