This is a report on a study conducted in the spring of 2011 to examine the cultural and social conditions associated with rebound effects on the household level. The goal of the study was to conduct an empirical, qualitative exploration of the conditions that favour rebound effects. In economics, rebound effects are defined to occur when a measure intended to increase energy efficiency actually contributes to an increase of energy consumption. Examples of conditions that favour rebound effects include using heat pumps for cooling, leaving energy‐saving light bulbs on for longer periods or neglecting to shut them off entirely, or…

The comfort and energy demand of a building are influenced significantly by glazed area of the facade. The glazed areas in the building are always challenging. Large glazing allows more daylight to get into the room but at the same time cause more heat gain and heat loss through the building envelop. Shading devices are very suitable elements for installing PV panels. The aim of this study is to evaluate the potential impact of different PV shading devices on energy performance and daylight of office buildings in Nordic climate. This dissertation is based on literature studies of relevant books and…

Denne rapporten begrenser seg til å presentere en metode for beregning av kuldebroverdier for tilslutningen mellom yttervegg og golv på grunn (ringmursløsninger). I både NS 3031 og NS‐EN ISO 10211 åpnes det for en forenklet beregning av kuldebroverdien etter en annen internasjonal standard; NS‐EN ISO 13370. Denne beskriver en forenklet prosedyre for beregning av U‐verdien til golv mot grunn basert på en korreksjon til U‐verdier beregnet etter NS‐EN ISO 6946.

Building Integrated Photovoltaic (BIPV) is an important source of renewable energy production for Zero Emission Buildings, even in Norwegian climate. In the planned Powerhouse 1 building at Brattøra in Trondheim the idea to reach a zero emission building level is to use PVs as a roofing material covering the entire roof. Challenges and questions raised in the design process of this building have motivated the work reported here.

The main aim of the work has been to do modeling and calculations of the energy use, embodied emission and the total CO2-emission for a typical Norwegian residential building. By doing this we try to reveal and study the main drivers for the CO2-emission, and also which performance is necessary for components and solutions in a Zero Emission Building according to the current Norwegian ZEBdefinition.

Authors:
Publication Year:

Carbon Debt and Carbon Payback time have recently been introduced into the Norwegian debate on greenhouse gas emissions, challenging the established view that Biofuels are carbon neutral. This report demonstrates that these new concepts are primarily a reflection of how the temporal system boundaries for CO2 emissions from biofuels are viewed. In a short term perspective it is possible that CO2 emissions from biofuels may have a non-zero short term climate effect, even though biofuels will be carbon neutral on the order of a century. Two alternative, more useful new concepts for analysis of climate effects of biofuels are described…

Vacuum insulation panels (VIPs) are a high-performance thermal insulation solution, which offer a much higher heat resistance than traditional insulation materials. Thus, is enabling a reduction in thickness of the building envelope, thereby solving one of the major challenges in today's requirements of energy-efficient buildings. Hence, the area efficiency in buildings will increase, and the slimmer walls may lead to increased daylight admission through the window partitions. Furthermore, it gives the possibility of retrofitting existing buildings towards today's standards within acceptable economical and practical measures. Reduction of thermal heat resistance is one of the major challenges when using VIP, thus…

Energiforsyning for bygning uten klimagassutslipp (ZEB) på Klimasenteret på Ringdalskogen

2013
I dag har bygninger en andel på 30 % av verdens energiforbruk og står for 20 % av klimagassutslippene globalt sett. Regjeringen har derfor som mål å skjerpe energikravene i byggeteknisk forskrift til passivhusnivå i 2015 og nesten nullutslippsnivå i 2020. For å oppnå et bygg med nesten nullutslippsnivå vil bygget normalt være tilknyttet nettet. Dette på bakgrunn av at energien importert fra energinettet, til bygningen, er ansvarlig for visse utslipp. Eksport av fornybar energi fra bygningen tilbake til energinettet er ansvarlig for å unngå lignende utslipp av andre (ikke-fornybare) energivarer koblet til samme energinett.Brødrene Dahl ønsker å se på…

Klassifisering av robusthet

Rapporten inneholder et forslag til system for klassifisering av byggetekniske løsningers robusthet. Hensikten med et slikt klassifiseringssystem skal gjøre det lettere for aktører i byggenæringen å velge løsninger og materialer tilpasset ønsket kvalitetsnivå, stedlig klima og den utførendes kompetanse. Byggenæringen må i større grad enn tidligere forholde seg til mange produkter med til dels overlappende bruksområde. Det kan være svært vanskelig å få oversikt over forskjeller i teknisk kvalitet og hvilke produkter som er mest hensiktsmessig i det enkelte byggeprosjekt.

Kondensfare uluftede loft. Feltundersøkelse

Tradisjonelt har norske småhus hatt et kaldt loft med lufteåpninger i takutstikket. Luftingen av loftet skulle både sørge for en kald takflate og hindre fuktskader på undertak og taksperrer. De siste årene har det blitt vanligere at småhus bygges med et uluftet, kaldt loftsrom. I stedet brukes et dampåpent undertak og lufting under taktekkingen. En del slike loftsrom har fått kondens og vekst av muggsopp på undertaket. Denne rapporten viser årsaker og viktige tiltak for å unngå problemet.

Isolering og fuktsikring av yttervegger mot terreng. Målinger i forsøksvegg

Publication Year:

Mange fuktproblemer viser at det er viktig å velge veggkonstruksjoner mot terreng med god sikkerhet mot skader. God sikkerhet mot kondensskader får man ved å plassere all isolasjon på utsiden eller inne i veggen. Men i svært mange nye byggeprosjekter i dag blir det benyttet en plass-støpt betongvegg som isoleres utvendig og innvendig. Den innvendige isolasjonen er ofte en bindingsverkvegg. Denne rapporten presenterer resultater fra målinger i et lite forsøkshus med en denne typen yttervegg mot terreng. Huset er bygd ved lokalene til SINTEF Byggforsk i Oslo
