A survey among relevant consultants and contractors shows the need for better knowledge and more systematic information in order to make decisions regarding the selection of system for energy supply of ZEBs (Zero Emission Buildings). The ZEB centre aims to develop a computerbased tool for this purpose that will include both a calculation tool and an information database. This assignment will be part of this development. The main objective of this work is to evaluate the cost optimality of different energy systems for a ZEB using the European cost optimal methodology introduced in the context of the EPBD (Energy Performance…

Zero emission buildings (ZEB) are buildings with a minimized energy consumption and renewable energy supply with zero greenhouse gas emissions. There is no common accepted definition of zero emission buildings. This is due to issues in defining the boundary of a balance in terms of building site and time frame of this balance. Further, there is no standard on accounting for emissions (on material, components, system, and building level) nor is there a standard for emissions from other building related environments. In this paper the goals for ZEB are specified and implications for components are discussed.

Abstract In highly-insulated buildings such as passive houses, the space-heating distribution subsystem can be simplified by reducing the number of heat emitters. In this context, the bi-directional flow through open doorways is known to be an efficient process to support the heat distribution between rooms. This process is therefore investigated using field measurements within a Norwegian passive house. The so-called large opening approximation proves to model fairly the mass flow rate, but also the convective heat transfer if the thermal stratification is accounted for. Furthermore, the discharge coefficient appears to be independent of the heater type and location in the…

The building enclosure plays a relevant role in the management of the energy flows in buildings and in the exploitation of solar energy at a building scale. An optimized configuration of the façade can contribute to reduce the total energy demand of the building. Traditionally, the search for the optimal façade configuration is obtained by analyzing the heating demand and/or the cooling demand only, while the implication of the façade configuration on artificial lighting energy demand is often not addressed. A comprehensive approach (i.e. including heating, cooling and artificial lighting energy demand) is instead necessary to reduce the total energy…

Publication Year:

Abstract Silica aerogels are a nanoporous material with extremely high porosity (up to ~99.8 %), low density (as low as ~0.005 g/cm3), and low thermal conductivity (~0.010–0.020 W/(mK)). Aerogels can also be made with a translucent or transparent state. These structural and functional features make aerogels a multifunctional material for many important applications. In this work, we discuss the perspective of aerogels as super insulation materials and window glazings in the building and construction sector. It shows that different research and development (R&D) strategies of aerogels shall be considered when aiming for different applications; reducing the manufacture cost, improving the…

The introduction of dynamic envelope components and systems can have a significant reduction effect on heating and cooling demands. In addition, it can contribute to reduce the energy demand for artificial lighting by better utilization of the daylight. One of these promising technologies is Phase Change Materials (PCM). Here, the latent heat storage potential of the transition between solid and liquid state of a material is exploited to increase the thermal mass of the component. A PCM layer incorporated in a transparent component can increase the possibilities to harvest energy from solar radiation by reducing the heating/cooling demand and still…

The main aim of this article is to rephrase good and bad performance of built environments as good or bad interplay of spaces, building technologies, and users. To support this perspective, two conceptual tools broadly used within the social study of technology are introduced. These concepts, the semiotic pair “script/antiprogram” and the study of “domestication of media and technology in everyday life,” were originally developed in the search for a better understanding of the mutual shaping of culture/society and technology. In this contribution, these concepts are applied in an empirical study of two nonresidential buildings. Through an extension of these…

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.

The demands for both thermal comfort and reduced energy consumption in buildings have become a major driving force for the increased use of advanced building automation and control systems (BACS). In the on-going development of Zero Emission Buildings (ZEBs), it seems to be a common understanding that such systems are needed in order to save energy and reach the zero emission goals, and that energy consumption for their operation is negligible compared to the building needs and the energy saving potential BACS causes. However, sensors and actuators in automation and control systems require electricity to operate, and both the environmental…

Conceptually a Zero Emission Building (ZEB) is a building with greatly reduced energy demand and able to generate electricity (or other carriers) from renewable sources in order to achieve a carbon neutral balance. However, a rigorous and agreed definition of ZEB is yet to come. A parallel paper in this conference explains how a formal and comprehensive ZEB definition can be based on the evaluation of certain criteria. These criteria are extensively discussed in ongoing projects, both in Norway and internationally. The objective of this paper is to focus on two of these criteria: energy performance and credits used to…

Responsive Building Elements (RBEs) and energy storage within the building are considered as a crucial development towards the nearly Zero Energy/Emission Building target. The exploitation at the building scale of renewable energy sources and the opportunities offered by the environment is achieved by the ability of the RBEs to dynamically adapt to changing environmental conditions. Among these concepts, Advanced Integrated Façades (AIFs) are probably one the most promising technologies, due to the important role that the building envelope plays in controlling the energy and mass flows between the building and the outdoor environment. In the framework of a decade-long research…

Abstract The ambition level for the zero emission neighbourhood Aadland is that the area will be self supplied with both thermal and electric energy. This paper presents how emissions from operation of the 500 dwellings are offset by on-site renewable energy production. The paper also describes a procedure for how to deal with embodied emissions from materials in an early stage design phase. The study verifies that it is possible to reach a zero emission balance for the neighbourhood. Zero emission from operation is achievable as an average for the neighbourhood. For individual zero emission buildings this also includes embodied emissions from materials and construction in…

Abstract Efficient energy recovery from used air with the goal of reducing energy use is important for realizing low energy houses. Rotary heat exchangers are very energy efficient, but have the drawback of transferring odours from exhaust air to fresh supply air. To avoid this, flat plate heat exchangers are commonly used where odour transfer might cause problems. Nevertheless, these may not properly handle water condensation and frost formation at low outdoor temperatures. The so-called membrane-based energy exchangers are an alternative to the flat plate heat exchanger. In a membrane-based exchanger, moisture is transferred from the humid exhaust air to…

The aim of the Norwegian research centre on Zero Emission Buildings(ZEB) is to develop competetive products and solutions of buildings with zero emission of greenhouse gases related to their production, operation and demolition. However, to develope solutions and concepts for zero emission buildings it is first necessarry to develop a sound definition of ZEB (for single buildings, and also cluster of buildings). During the first 3 years of the centres running, significant work have been done to adress different issues related to the ZEB-definition, among them defining CO2 factors for various energy wares. Work done in the International Energy Agency…
