Publication Year:
2013
Stricter energy regulations for energy use in buildings require new construction to be equipped with increasingly thicker insulation layers and minimal surfaces for glazing in cold climates. In recent years a new type of window has been proposed as a way to overcome the notoriously low thermal performance of transparent surfaces. In order to reach such performances, this glazing type has been equipped with monolithic aerogel as the glass-pane filling. The scope of this study is a comprehensive analysis of greenhouse gas emissions from the partial substitution of typical triple-glazing-with-argon units with double-glazing-with-monolithic-aerogel units in residential building upgrades. A social…

Abstract New buildings have to satisfy ever-tightening standards regarding energy efficiency and consumption. This results in higher insulation levels and lower air leakages that reduce heating demands. However, even at moderate outdoor temperatures these buildings are easily warmed up to such a degree that in order to ensure acceptable indoor environment quality, removal of excess heat becomes unavoidable. Use of electric energy related to mechanical cooling is considered incompatible with achieving zero energy buildings (ZEB). The use of ventilative cooling (VC) in combination with mechanical cooling means energy consumption reduction due to lower use of mechanical ventilation and cooling system.This…

The aim of the study was to define an energy supply solutions for a low-energy commercial building in cold climates. A new low-energy office building built with high quality building insulation better than the Norwegian passive building standard was analyzed by using EnergyPlus. The results showed that the heat pump solutions could be used to cover the building base load, while the peak load should be covered by additional energy sources. Due to a high indoor temperature caused by the high quality building insulation standard, an increase in ventilation air flow was necessary during the summer. To fully utilize the…

In order to be successful on the market, energy-saving measures for existing buildings need to be promoted with arguments that are directly relevant to the users. Initial marketing for energy retrofitting has been based on monetary profits from future energy savings. However, for most households in Europe, energy bills for the home account for only 3-4 percent of disposable income, hence are not a major concern. As a result of inappropriate promotion of energy savings for existing buildings, less than 1 percent of over 300.000 projects certified by BREEAM are refurbishments. Apparently, the promotion of energy retrofitting needs to be…

Responsive Building Elements (RBEs) are technologies for the exploiting at the building scale renewable energy sources and the opportunities offered by the environment. Among the RBE concepts identified by the IEA-ECBCS Annex 44, Advanced Integrated Façades (AIFs) is probably one of the most promising technologies. Important players in the field of the façade have started to develop integrated modular façade systems (Multifunctional Façade Modules - MFMs), with a dynamic behaviour and interacting with the other building services, in order to reduce the building energy consumption and maximize the indoor comfort conditions. In the frame of a research activity aimed at…

Abstract This paper deals with the experimental assessment of the energy performance of two Advanced Integrated Façade modules (AIF) characterized by two very similar configurations. The two AIF modules were installed on the south-exposed façade of an outdoor test cell facility (a real-scale mockup of an office building) and continuous measurements were carried out for more than one year. Data collected during the experimental campaign were analyzed to evaluate the energy performance and thermo-physical behaviour of the AIF modules. The performances of the two systems were assessed by comparison and by means of conventional and advanced synthetic metrics. The results…

Façades play an important role in architecture, with deep implications in both the quality of the indoor environment and the appearance of the building. R&D in the field of energy conservation is moving toward advanced integrated façades (AIFs): these are innovative and dynamic façades deeply connected with the building equipment. Their dynamic features allow the energy performance of the façade to be optimized, adapting its behavior to different boundary conditions. The substantial lack of synthetic performance parameters to assess and to characterize the energy performance of AIFs is one of the main limitations to the widespread of these technologies. This…

Publication Year:

Net zero energy buildings (nZEBs) are understood as grid-connected buildings which do not require net inputs of non-renewable energy over a defined period of their life cycle. Energy requirements of nZEBs have until now been assessed based on the impact buildings have on the existing energy system. This paper introduces a new approach to nZEB energy balance that takes into account the actual amount of energy nZEBs require. Energy balance methods previously proposed for nZEBs are illustrated in a new way and expressed in a series of equations based on a common terminology. Taking a different standpoint on the very…

Sandwich elements are widely used in the building envelope, in walls and foundations in particular. The thickness of sandwich elements is increasing as the demand for reduced heat loss from the building envelope is required. The building industry is searching for means and alternative materials to reduce the volume of the building envelope, but at the same time obtain the same thermal performance. Sandwich element constructions might be suitable for highly effective insulation materials as VIPs (Vacuum Insulation Panels). The possibilities of optimizing the thermal performance and by the same time decreasing the thickness and reducing the volume of aggregated…

The current state and future challenges of energy and buildings research are explored from the perspective of the social study of science. Major trends in knowledge production are considered for practices within current energy and buildings research. New forms of knowledge production hold the potential to provide clearer strategies to overcome barriers between researchers and practitioners. These are investigated through an explorative survey of researchers based on their own accounts of energy and buildings research, their expectations of future challenges, and their perceptions of ‘good’ science. Two sets of challenges from knowledge production arise for building energy research. First, with…

I ZEB, og som en del av arbeidspakke 5 "Konsepter og strategier for nullutslippsbygg", er det gjennomført en studie av to energikonsepter for boligområdet Ådland i Bergen. Ådland ligger ved Flesland rett sør for Bergen sentrum. ByBo AS ønsker å bygge ut fra 500 – 800 boliger på området hvor både de enkelte boligene og området som helhet skal oppfylle kriterier for nullutslippsbygg. I ZEB er det definert ulike ambisjonsnivå for nullutslippsbygg. Den gjennomførte studien anbefaler et ambisjonsnivå ZEB-O som et gjennomsnitt for Ådland området. ZEB-O betyr at området skal være selvforsynt med energi, inklusive elektrisitet og varme, over et…

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…

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…

Zero emission building (ZEB) is considered a future-oriented concept for reducing Green house gas emissions in the bulding sector. Which aspects should be considered when designing a zero emission building? The largest potential for decreasing emissions comes from improving energy efficiency, conscious choice of materials and renewable energy supply. The project investigates each aspect providing different design alternatives which give a basis for possible decisions on carbon neutral strategy.

Abstract Greenhouse gas (GHG) emissions from the combustion of fossil energy need to be reduced to combat global climate change. For zero energy and Zero Emission Buildings (ZEB), photovoltaic solar energy systems are often installed. When the goal is to build a life cycle Zero Emission Building, all emissions come under scrutiny. Emissions from photovoltaic (PV) energy systems in Zero Emission Buildings have been shown to have a relative large share of material emissions. In this paper, we compare GHG emissions per kW h of electricity and greenhouse gas emission payback times (GPBT) for three residential PV systems in Zero Emission…
