This \nwill be the case in particular for such buildings, where the building constructions in contact with the \nground take up a considerable part of the total area of the building envelope. On the one hand this \nsituation is given for small buildings provided with a basement. On the other hand transmission heat \nlosses through the ground are important for buildings with big floor areas in direct contact to the ground, e. g. for big halls. \nTransmission heat losses from a basement of a residential building were investigated in [1] and [2]. This paper deals with heat losses through various slab on ground constructions normally used for big industrial halls. \nCalculations of the heat flow through building constructions in contact with the ground are special cases on principle in that they cannot be done using the ordinary constant, onedimensional (1D) thermal model. On the one side the heat flow through the ground can be described only using two or three spacial coordinates. From this heat losses through the ground are to be calculated using two- and threedimensional (2D and 3D) thermal models. On the other side in most cases of interest the very big heat storage capacity of the ground involved in such heat flow calculations cannot be ignored, so that a non-steady calculation method is required. \nFor most slab shaped building constructions in contact with the air the thermal quality of the \nconstruction with regard to heat losses can be characterized by an U-value in good approximation. \nContrary to this the declaration of a U-value alone makes no sense for slab on ground constructions. \nThe well known fact that the heat loss through a slab-shaped building construction can be calculated \nin good approximation by multiplying the U-value of the slab with it's area and with the difference \nof the air temperatures between internal and external environment is no longer true for slab on \nground constructions. The heat flow through slabs on ground is not only influences by the U-value \nand the area of the slab but also by the geometry of the building construction in contact with the ground and by the thermal characteristics of the surrounding soil. For that reason quantitative state-\nments concerning the heat through the ground are only true for the specific building under consider-\nation. \nIn this paper a case study concerning different insulation levels of a slab on ground construction \nis performed for an industrial hall with largely fixed geometry. From this study qualitative conclu-\nsions concerning the effectiveness of slab insulation is drawn.", "type": "", "date": "", "publisher": "", "place": "", "DOI": "", "citationKey": "", "url": "http://www.kornicki.com/antherm/Help/Content_EN/Theory/BUD_95G.pdf", "accessDate": "", "archive": "", "archiveLocation": "", "shortTitle": "", "language": "", "libraryCatalog": "", "callNumber": "", "rights": "", "extra": "", "tags": [], "collections": [ "EJNG7IDZ" ], "relations": {}, "dateAdded": "2012-04-25T20:54:55Z", "dateModified": "2012-04-25T21:00:12Z" } }, { "key": "U4TRT5NH", "version": 4, "library": { "type": "group", "id": 74663, "name": "Earth Tubes - EAHE - ETAHE - LEWT - ATEHE", "links": { "alternate": { "href": "https://www.zotero.org/groups/earth_tubes_-_eahe_-_etahe_-_lewt_-_atehe", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/74663/items/U4TRT5NH", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/earth_tubes_-_eahe_-_etahe_-_lewt_-_atehe/items/U4TRT5NH", "type": "text/html" } }, "meta": { "createdByUser": { "id": 932721, "username": "anper47", "name": "Antonio Peretti", "links": { "alternate": { "href": "https://www.zotero.org/anper47", "type": "text/html" } } }, "creatorSummary": "HAGENTOFT", "parsedDate": "1988", "numChildren": 0 }, "data": { "key": "U4TRT5NH", "version": 4, "itemType": "report", "title": "HEAT LOSS TO THE GROUND FROM A BUILDING", "creators": [ { "creatorType": "author", "firstName": "Carl-Eric", "lastName": "HAGENTOFT" } ], "abstractNote": "heated building induce a heat flow from the building fundation into the ground.", "reportNumber": "", "reportType": "", "institution": "Department of Building Technology - Lund Institute of Technology - Sweden", "place": "", "date": "1988", "seriesTitle": "", "seriesNumber": "", "pages": "", "DOI": "", "ISBN": "", "citationKey": "", "url": "http://www.byfy.lth.se/fileadmin/byfy/files/TVBH-1000pdf/CEH-1004PartA.pdf", "accessDate": "", "ISSN": "", "archive": "", "archiveLocation": "", "shortTitle": "", "language": "", "libraryCatalog": "", "callNumber": "", "rights": "", "extra": "", "tags": [], "collections": [ "EJNG7IDZ" ], "relations": {}, "dateAdded": "2012-04-25T20:49:20Z", "dateModified": "2012-04-25T20:52:34Z" } }, { "key": "IPHD6QRJ", "version": 5, "library": { "type": "group", "id": 74663, "name": "Earth Tubes - EAHE - ETAHE - LEWT - ATEHE", "links": { "alternate": { "href": "https://www.zotero.org/groups/earth_tubes_-_eahe_-_etahe_-_lewt_-_atehe", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/74663/items/IPHD6QRJ", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/earth_tubes_-_eahe_-_etahe_-_lewt_-_atehe/items/IPHD6QRJ", "type": "text/html" } }, "meta": { "createdByUser": { "id": 932721, "username": "anper47", "name": "Antonio Peretti", "links": { "alternate": { "href": "https://www.zotero.org/anper47", "type": "text/html" } } }, "creatorSummary": "HAGENTOFT and BLOMBERG", "numChildren": 0 }, "data": { "key": "IPHD6QRJ", "version": 5, "itemType": "document", "title": "SLAB - Heat losses to the ground from buildings", "creators": [ { "creatorType": "author", "firstName": "Carl-Eric", "lastName": "HAGENTOFT" }, { "creatorType": "author", "firstName": "Thomas", "lastName": "BLOMBERG" } ], "abstractNote": "The PC-programSLAB calculates the heat loss to the ground from an evenly insulated rectangular slab on the ground.

We determined how the season, soil thermal conductivity and pipe spacing influence energy transfer from the soil to the ATEHE and also the steel-pipe contribution to this energy transfer.", "publicationTitle": "Energy", "publisher": "", "place": "", "date": "Giugno 1999", "volume": "24", "issue": "6", "section": "", "partNumber": "", "partTitle": "", "pages": "519-523", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "", "DOI": "10.1016/S0360-5442(99)00012-2", "citationKey": "", "url": "http://www.sciencedirect.com/science/article/pii/S0360544299000122", "accessDate": "2012-04-23T17:01:26Z", "PMID": "", "PMCID": "", "ISSN": "0360-5442", "archive": "", "archiveLocation": "", "shortTitle": "", "language": "", "libraryCatalog": "ScienceDirect", "callNumber": "", "rights": "", "extra": "", "tags": [], "collections": [ "8GXTDQ7Q" ], "relations": {}, "dateAdded": "2012-04-23T17:01:26Z", "dateModified": "2012-04-23T17:01:26Z" } }, { "key": "RWI5DSZ2", "version": 1, "library": { "type": "group", "id": 74663, "name": "Earth Tubes - EAHE - ETAHE - LEWT - ATEHE", "links": { "alternate": { "href": "https://www.zotero.org/groups/earth_tubes_-_eahe_-_etahe_-_lewt_-_atehe", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/74663/items/RWI5DSZ2", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/earth_tubes_-_eahe_-_etahe_-_lewt_-_atehe/items/RWI5DSZ2", "type": "text/html" }, "up": { "href": "https://api.zotero.org/groups/74663/items/C3ZTA3E7", "type": "application/json" } }, "meta": { "createdByUser": { "id": 932721, "username": "anper47", "name": "Antonio Peretti", "links": { "alternate": { "href": "https://www.zotero.org/anper47", "type": "text/html" } } } }, "data": { "key": "RWI5DSZ2", "version": 1, "parentItem": "C3ZTA3E7", "itemType": "attachment", "linkMode": "linked_url", "title": "ScienceDirect Full Text PDF", "accessDate": "2012-04-23T17:01:26Z", "url": "http://www.sciencedirect.com/science?_ob=ShoppingCartURL&_method=add&_eid=1-s2.0-S0360544299000122&originContentFamily=serial&_origin=article&_acct=C000228598&_version=1&_userid=10&_ts=1335200446&md5=7ff2de2f1e41b25988480733b61f1a2c", "note": "", "contentType": "application/pdf", "charset": "", "tags": [], "relations": {}, "dateAdded": "2012-04-23T17:01:26Z", "dateModified": "2012-04-23T17:01:26Z" } }, { "key": "H3Z68TPG", "version": 1, "library": { "type": "group", "id": 74663, "name": "Earth Tubes - EAHE - ETAHE - LEWT - ATEHE", "links": { "alternate": { "href": "https://www.zotero.org/groups/earth_tubes_-_eahe_-_etahe_-_lewt_-_atehe", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/74663/items/H3Z68TPG", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/earth_tubes_-_eahe_-_etahe_-_lewt_-_atehe/items/H3Z68TPG", "type": "text/html" }, "up": { "href": "https://api.zotero.org/groups/74663/items/C3ZTA3E7", "type": "application/json" } }, "meta": { "createdByUser": { "id": 932721, "username": "anper47", "name": "Antonio Peretti", "links": { "alternate": { "href": "https://www.zotero.org/anper47", "type": "text/html" } } } }, "data": { "key": "H3Z68TPG", "version": 1, "parentItem": "C3ZTA3E7", "itemType": "attachment", "linkMode": "linked_url", "title": "ScienceDirect Snapshot", "accessDate": "2012-04-23T17:01:26Z", "url": "http://www.sciencedirect.com/science/article/pii/S0360544299000122", "note": "", "contentType": "text/html", "charset": "", "tags": [], "relations": {}, "dateAdded": "2012-04-23T17:01:26Z", "dateModified": "2012-04-23T17:01:26Z" } }, { "key": "CAHT7VXH", "version": 1, "library": { "type": "group", "id": 74663, "name": "Earth Tubes - EAHE - ETAHE - LEWT - ATEHE", "links": { "alternate": { "href": "https://www.zotero.org/groups/earth_tubes_-_eahe_-_etahe_-_lewt_-_atehe", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/74663/items/CAHT7VXH", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/earth_tubes_-_eahe_-_etahe_-_lewt_-_atehe/items/CAHT7VXH", "type": "text/html" }, "up": { "href": "https://api.zotero.org/groups/74663/items/U6BEZSNE", "type": "application/json" } }, "meta": { "createdByUser": { "id": 932721, "username": "anper47", "name": "Antonio Peretti", "links": { "alternate": { "href": "https://www.zotero.org/anper47", "type": "text/html" } } } }, "data": { "key": "CAHT7VXH", "version": 1, "parentItem": "U6BEZSNE", "itemType": "attachment", "linkMode": "linked_url", "title": "Snapshot", "accessDate": "2012-04-23T16:59:43Z", "url": "http://scitation.aip.org/getabs/servlet/GetabsServlet?prog=normal&id=JSEEDO000126000001000620000001&idtype=cvips&gifs=yes&ref=no", "note": "", "contentType": "text/html", "charset": "", "tags": [], "relations": {}, "dateAdded": "2012-04-23T16:59:43Z", "dateModified": "2012-04-23T16:59:43Z" } } ]
