Thermal comfort is one of the most important factors for the success of design. Many investigations have been made since people realized the importance of energy conservation in a building. PCM is an example of such innovation in building material that helps to maintain the thermal comfort in building and also lessen the energy demand. PCM works on a principle of latent heat storage in which the material is capable of storing the heat while it reaches melting and later releases this heat in useful form. This thesis looks into the behavior of PCM when applied on different building component…

Thermo-physical behaviour and energy performance assessment of PCM glazing system configurations: A numerical analysis
Authors:
Publication Year:

Authors:
Publication Year:
2012
The adoption of Phase Change Materials (PCMs) in glazing systems was proposed to increase the heat capacity of the fenestration, being some PCMs partially transparent to visible radiation. The aim of the PCM glazing concept was to let (part) of the visible spectrum of the solar radiation enter the indoor environment, providing daylighting, while absorbing (the largest part of) the infrared radiation. In this paper, the influence of the PCM glazing configuration is investigated by means of numerical simulations carried out with a validated numerical model. Various triple glazing configurations, where one of the two cavities is filled with a…

On the integration of wood stoves for the space-heating of passive houses: Assessment using dynamic simulation

State-of-the-art wood stoves could be an attractive solution for the space heating of passive houses. The question of the integration of wood stoves in passive envelopes is rather new and still open, the main constraints being the power oversizing ant the heat distribution. The paper proposes a low-resolution simulation approach to provide an insight into the whole-year thermal comfort using a stove, and into the relative effect of the large number of physical parameters involved in the problem. In particular, a simple stove model is developed for detailed dynamic simulations in order to fairly represent the heat emission properties of…

Characterization of the optical properties of a PCM glazing system

Authors:
Publication Year:

The optical characteristics of an advanced glazing system are presented in this paper. The investigated glazing system is based on the incorporation of a paraffin-based Phase Change Material (PCM) into a transparent component, made of two extra-clear glass panes and a cavity where the PCM layer is placed. Due to the highly scattering property of the system (when the PCM is in solid state), the use of a large integrating sphere equipment (75 cm diameter) is necessary to obtain reliable results. The spectral transmission, reflection and absorption coefficients of the PCM glazing system are measured between 400 and 2000 nanometers,…

Comparative Analysis of PV Shading Devices for Energy Performance and Daylight

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…

In order to minimize the energy use for heating, passive houses for residential use are constructed using heavy insulation. In addition, they have minimal air leakages and no vents in exterior walls for direct supply of fresh air, and thus, mechanical ventilation systems are a mandatory requirement in such buildings. With the aim of reducing energy use, efficient energy recovery from used air will be of high importance. In residential buildings with several living units, centralized air handling units are regarded as the most energy efficient system. However, to prevent odours to transfer between apartments it is important to avoid…

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

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
