BUILD RAPPORT 2023:11 Klimadata til fugtsimuleringer Referenceår

Dette projekt omhandler udarbejdelse af et referenceår til anvendelse ved varme- og fugtsimuleringer (hygrotermiske simuleringer). Referenceåret er udarbejdet på baggrund af historiske data for perioden 2001-20019 for Sjælsmark. Det er hensigten at referenceåret kan anvendes af projekterende og udførende til at gennemføre fugtsimuleringer og bedømme konstruktioner ud fra danske klimadata. Rapport beskrivelse: Bygningsreglementet foreskriver, at bygninger skal konstrueres og udføres så fugtskader undgås fx skimmelvækst. Bygningers konstruktioner påvirkes af fugt fra udeklimaet og indefra af bygningens brug. En måde til at dokumentere, at konstruktioner er projekteret uden risiko for fugtskader, er ved at udføre en simulering af varme- og fugtforholdene i konstruktioner. I Danmark findes der ikke et simuleringsprogram, som skal anvendes til simuleringer, men der anvendes forskellige programmer fx WUFI® Pro og DELPHIN. Disse programmer har ikke danske klimadata, og derfor anvendes nærliggende klimadata fra fx Lund, Sverige eller Bremerhaven, Tyskland. Denne rapport omhandler udarbejdelse af et referenceår til anvendelse ved varme- og fugtsimuleringer (hygrotermiske simuleringer). Referenceåret er udarbejdet på baggrund af historiske data for perioden 2001-2019 for Sjælsmark, suppleret med nedbørs data fra Holbæk flyveplads, Hillerød SØ, Store Hareskov og Gørløse for perioden 2001-2010. Rapporten er udformet så den dokumenterer grundlaget for referenceåret. Det er hensigten, at referenceåret kan anvendes af projekterende og udførende til at gennemføre fugtsimuleringer og bedømme konstruktioner ud fra danske klimadata. Rapporten er udarbejdet af post.doc Nickolaj Feldt Jensen, adjunkt Tessa Kvist Hansen og seniorforsker Martin Morelli, fra Institut for Byggeri, By og Miljø og adjunkt Anne Marie Svane og professor Rasmus Waagepetersen fra Institut for Matematiske Fag.

Supplementary data for: "Fire safety evaluation of different internal insulation measures in Danish and European context"

Supplementary data for: N.F. Jensen, M. Morelli, L.S. Sørensen, 2021. "Fire safety evaluation of different internal insulation measures in Danish and European context" Abstract:In about the last 10 years there has been an increased focus on energy upgrading the existing building stock. This have included several international and national projects dealing with internal insulation. Many of the studies have considered the internal insulation as a measure to achieve a specific energy consumption of buildings. Later, the focus has been on the durability of the ‘new’ structure with additional insulation on the internal side of walls, i.e. if the measure is moisture safe. These measures have been applied in both theoretical studies, laboratory and real buildings. None of the studies has reported whether or not the suggested retrofit measures fulfil respective fire regulations. The height of the building is also considered in fire regulations, and therefore, measures that are applicable in e.g. single-family houses might not be applicable in apartment buildings. This study includes a review of a number of different insulation materials and – systems used for internal insulation. These measures are evaluated against the EU-harmonized and Danish fire regulations, as many countries might have adapted national requirements. The study evaluates, whether the measure are applicable at all floor levels or not. The dataset comprises an Excel file containing a review and evaluation of a number of case projects where internal insulation was installed in buildings with preservation worth façade walls, to determine if the studies met the fire requirements. Detailed information and references to the scientific publications for each of the examined case projects are provided

Supplementary data for: "Hygrothermal assessment of internally insulated historic solid masonry walls with focus on the thermal bridge due to internal partition walls"

Supplementary data for: N.F. Jensen, C. Rode, E.B. Møller, 2021, "Hygrothermal assessment of internally insulated historic solid masonry walls with focus on the thermal bridge due to internal partition walls"The article is submitted for review for the International Building Physics Conference 2021.The authors are awaiting link/DOI for the article. This study investigated the hygrothermal performance of five thermal insulation systems for internal retrofitting purposes. Focus was on the hygrothermal performance near partition brick walls compared to the middle of the wall. The setup consisted of two 40-feet (12.2 m) insulated reefer containers with controlled indoor climate, reconfigured with several holes (1x2 m each) containing solid masonry walls with embedded wooden elements on the interior side, an internal brick partition wall and different internal insulation systems, with and without exterior hydrophobisation. Relative humidity and temperature were measured over five years in the masonry/insulation interface and near the interior surface, in the centre of the test field and near the internal partition wall. In addition, calibrated numerical simulations were performed for further investigation of the thermal bridge effect. The datasets comprises:1) Measurements from the experimental setup (hourly and 96-hour average values)2) Visual representations of the measurements from the experimental setup 3) VTT mould growth modelling (calculation files and results)4) Calibrated Delphin simulation models (including Output JPG files
