Roof-integrated PV in Nordic climate - Building physical challenges
Gullbrekken, Lars; Kvande, Tore; Time, Berit (Journal article; Peer reviewed, 2015)Use of photovoltaics (PV) is key remedies in buildings where a large part of the energy supply should be based on renewable energy. PV in Nordic climate can be challenging because of and temperatures below zero. The aim ... -
Schools on hold – how simple measures can help improving the indoor environment in schools
Clauß, John; Wågø, Solvår Irene; Gullbrekken, Lars (SINTEF Proceedings;9, Chapter; Peer reviewed; Conference object, 2021)This work presents the lessons-learned from a Norwegian project called "Skoler på vent" – "Schools on hold" – which is aiming at finding simple and effective measures for improving the indoor climate in schools that have ... -
Skoler på vent. Tiltak for å ivareta inneklima og helse
Wågø, Solvår Irene; Clauß, John; Mathisen, Hans Martin; Gustavsen, Kai; Gullbrekken, Lars; Homb, Anders (SINTEF Fag;85, Research report, 2021)Målet for prosjektet "Skoler på vent" har vært å kartlegge innemiljøet og innemiljø-relaterte helseutfordringer i skolebygninger som er satt på vent, det vil si skolebygninger som venter på oppgraderinger eller som skal ... -
Tetting av bygningskroppen ved bruk av teipprodukter
Geving, Stig; Sletnes, Malin; Gullbrekken, Lars; Frank, Susanne Gabriele Martha; Rüther, Petra (SINTEF Fag;102, Research report, 2023)Forord.Denne rapporten oppsummerer resultatene fra kunnskapsprosjektet TightEN – Durable adhesive airtight solutions for energy effective building envelopes (2019–2023). Rapporten er et resultat av omfattende forskningsarbeid ... -
The Effect of Repeated Moisture Cycles on the Air Tightness of Traditional Clamped Vapour Barrier Joints
Geving, Stig; Norvik, Øyvind; Gullbrekken, Lars (Journal article, 2019)In this study it has been investigated whether and to what extent, repeated moisture cycles affect the airleakage through clamped overlap joints in the vapour barrier layer. Use of clamped joints is a traditionalway to ... -
Thermal mass and thermal comfort in offices – experimental studies of a concrete floor
Grynning, Steinar; Nocente, Alessandro; Gullbrekken, Lars; Skjeggerud, Kjell (CESBP 2019, Conference object; Journal article; Peer reviewed, 2019)Previous studies demonstrated that the use of thermal mass in buildings can contribute to reduce the energy demand and improve the thermal comfort. The thermal mass effect strongly depends on the properties of the materials ... -
Thermal Performance of Insulated Constructions—Experimental Studies
Gullbrekken, Lars; Grynning, Steinar; Gaarder, Jørn Emil (Journal article; Peer reviewed, 2019)Buildings that are designed to meet high-energy performance requirements, e.g., passive houses, require well-insulated building envelopes, with increased insulation thicknesses for roof, wall and floor structures. We ... -
Thermo-fluid dynamic performance of a ventilated pitched roof: Numerical modelling and experimental validation
Moschetti, Roberta; Nocente, Alessandro; Geving, Stig; Gullbrekken, Lars (Peer reviewed; Journal article, 2022)Wooden ventilated pitched roofs represent a widely spread construction solution in Nordic countries. They have several benefits, including the drainage of excessive moisture from the construction and the reduction of the ... -
Towards Upgrading Strategies for nZEB-Dwellings in Norway
Gullbrekken, Lars; Time, Berit (Journal article, 2019)Recent work suggests that upgrading in line with the Norwegian building regulations or by upgrading to the requirements of the national passive house norm, NS3700, can enable nZEB level to be achieved. The aim of this work ... -
Unngå at vinduene blir boligens kjøleelement
Asphaug, Silje Kathrin; Rüther, Petra; Gullbrekken, Lars (Journal article, 2022)Det er flere gode grunner til å velge vinduer med trelags isolerglass fremfor tolags. Sparte kroner og økt komfort er kanskje de viktigste for boligeiere. -
Vapour resistance of wind barrier tape: Laboratory measurements and hygrothermal performance implications
Johnsen, Ida-Helene; Andenæs, Erlend; Gullbrekken, Lars; Kvande, Tore (Peer reviewed; Journal article, 2021)In the building industry, the interest into adhesive tape to achieve a more tight and robust building envelope has increased rapidly in recent years. With an increasing demand for energy efficiency in buildings, national ... -
Veileder for prosjektering av passivhus – småhus
Myhre, Lars; Schild, Peter G.; Pettersen, Trine Dyrstad; Blom, Peter; Gullbrekken, Lars (Prosjektrapport (SINTEF Byggforsk);105, Research report, 2012)Kapittel 1 presenterer de norske passivhuskravene gitt i standarden NS 3700:2010. Oppvarmingsbehovet skal beregnes med lokale klimadata, og ikke med standard referanseklima som etter rammekrav i TEK10. NS 3700 har et areal- ... -
Watertight insertion of heavy sliding doors in exterior walls
Andenæs, Erlend; Raugstad, Torill; Strid, Jonas; Gullbrekken, Lars; Kvande, Tore (Peer reviewed; Journal article, 2023)The joints around heavy terrace doors are considered a weak point in rain-exposed façades, as it is vulnerable to defects in design and construction. The insertion process of heavy sliding doors is a notable challenge. ... -
Wind pressure coefficients for roof ventilation purposes
Gullbrekken, Lars; Uvsløkk, Sivert; Kvande, Tore; Pettersson, Kaj; Time, Berit (Journal article; Peer reviewed, 2018)Wind pressure coefficients (cp) are important inputs for analytical calculations of wind load.
