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.

Addressing the problem of knowledge integration across the building sectors, a critical stance is taken and tested conceptually, as well as experimentally within an interdisciplinary frame that draws together a number of key literatures from architecture, building science, urban studies, and STS. Empirically, the thesis is supported by a set of interviews and questionnaires that form a grounded case of Switzerland, which evaluates the assumptions and practices around sustainability policies and carbon reduction strategies for buildings and the built environment. As an article based dissertation comprised of four articles that are summarized below, the thesis aims to constructively connect theoretical…

The adoption of Phase Change Materials (PCMs) in building components is an up-to-date topic and a relevant number of research activities on this issue are currently on the way. A particular application of PCMs in the building envelope focuses on the integration of such a kind of material into transparent envelope components. A numerical model that describes the thermo-physical behaviour of a PCM layer in combination with other transparent materials (i.e. glass panes) has been developed to perform numerical analyses on various PCM glazing systems configurations. The paper illustrates the structure of the model, the main equations implemented and the…

Accelerated ageing and durability of double-glazed sealed insulating windows panes and impact on heating demand in buildings

Publication Year:
2016
Abstract A crucial property for double-glazed sealed insulating window panes is to maintain their thermal insulating properties and thus low U-values. However, degradation and thus subsequent reduction or loss of low-conductance gas concentration may occur in the sealed glazing units by their exposure to outdoor climate. The choice of spacers is important to keep as low thermal transport through the window panes as possible, i.e. low U-value. In addition, the type of spacers may also influence their durability and resistance towards ageing, which hence may be characterized by the low-conductance noble gas concentration, e.g. argon, krypton or xenon. Ageing and…

This report deals with how to define what a Zero Emission Building (ZEB) is with explanation and analysis of different parameters related to embodied emissions of CO2 equivalents. The report can be used as a guidance tool on how to assess embodied emissions, and also on what parameters should be evaluated in such an assessment. Different ambition levels for ZEBs may include life stages, operation, material, construction and end-of-life and can be documented according to EN 15978. Calculation procedures should include system boundaries, embodied emissions from materials, transport, the construction process and waste handling according to the ambition level. CO2 eq…

The impact of an ideal dynamic building envelope on the energy performance of low energy office buildings

Publication Year:
2014
Abstract This paper shows the results of a research activity aimed at assessing the advantages of an ideal adaptive building skin over conventional building envelope systems. The basic idea underlying the research consists in imagining an ideal building envelope system characterised by the capability of continuously changing (within a certain range) some of its thermo-physical and optical properties. The reason for the continuous tuning of thermo-physical and optical properties lies in the assumption that an optimised (fixed) configuration, where the properties do not change over time, is not able to minimise the total energy demand of the building at each…

Abstract The Zero Village Bergen consists of a total floor area of ca. 92 000 m2, with more than 700 dwellings divided between terraced houses (68% of total floor area) and apartment blocks (25%) and some area dedicated to non-residential purposes such as offices, shops, and a kindergarten (7%). The project is currently in the planning phase and the strategy for achieving the ZEB-O goal1 is based on three steps: first, minimize energy demand through energy efficiency of the buildings; second, maximize PV generation on the buildings' footprint; and third, consider additional measures onsite and nearby (e.g. local heating system…

Abstract Low-emissivity (low-e) materials can be used in order to reduce energy usage in both opaque and transparent areas of a building. The main focus for low-e materials is to reduce the heat transfer through thermal radiation. Furthermore, low-e materials will also influence on the daylight and total solar radiation energy throughput in windows, the latter one often characterized as the solar heat gain coefficient (SHGC). This work reviews low-e materials and products found on the market, and their possible implementations and benefits when used in buildings. The SHGC is often left out by many countries in energy labellings of…

Moving away from the annual energy budget and including the emissions of the entire building lifetime during construction, operation, and disposal is a key aspect of ZEB. This can be summarised in an emission inventory of operation and building components and services. The aim of this paper is to investigate the emission balance of both operational and the embodied energy in different highly energy efficient buildings concepts which are worth considering toward achieving Zero emission buildings. In this work four concepts for energy efficient buildings are identified which could provide stepping stones towards a definition of ZEB. These concepts were…

Abstract This paper presents a review of projects where hybrid photovoltaic-thermal (PV/T) systems are used in buildings. PV/T systems convert solar radiation to electricity and heat simultaneously, in one module. The output of both electricity and heat suggests that the technology can be suited for use in buildings, especially when the available area for installation is limited. The market and research activities related to PV/T technology has increased in recent years. This article adds to existing reviews on PV/T technology by focusing on the building perspective. Different strategies for the use of PV/T in buildings are discussed, and examples of…

“Powerhouse” is an alliance that will demonstrate that it is possible to build plus-energy buildings in cold climates, such as in Norway. For the Powerhouse project in Trondheim (Brattørkaia 17a), PV panels will produce and offset the delivered energy needed during the operation and for compensating the embodied energy of the building. The building will thus export more electricity than it will use for operation. In a broader environmental perspective, an aim of this project is also to achieve the classification “Outstanding” in the BREEAM-NOR environmental certification scheme. Energy efficiency measures and materials with low embodied energy have been crucial…

Abstract This study examined an integrated solution of the building energy supply system consisting of flat plate solar thermal collectors in combination with a ground-source heat pump and an exhaust air heat pump for the heating and cooling, and production of domestic hot water. The supply energy system was proposed to a 202 m2 single-family demo dwelling (SFD), which is defined by the Norwegian Zero Emission Building standard. The main design parameters were analyzed in order to find the most essential parameters, which could significantly influenced the total energy use. This study found that 85% of the total heating demand of the…

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…

Abstract Glass represents an important and widely used building material, and crucial aspects to be addressed include thermal conductivity, visible light transmittance, and weight for windows with improved energy efficiency. In this work, by sintering monolithic silica aerogel precursors at elevated temperatures, aerogel glass materials were successfully prepared, which were characterized by low thermal conductivity [k ≈ 0.17–0.18 W/(mK)], high visible transparency (Tvis ≈ 91–96 % at 500 nm), low density (ρ ≈ 1.60–1.79 g/cm3), and enhanced mechanical strength (typical elastic modulus Er ≈ 2.0–6.4 GPa). These improved properties were derived from a series of successive gelation and aging steps during the desiccation of silica aerogels. The involved sol → gel → glass transformation was investigated by means…

Abstract This paper investigates the drivers and barriers for green leasing associated with the relationship between building owners and tenants, whilst also considering the extent to which this should be considered during the life cycle phases of a building. The procurement of appropriate rental property and its services is an important consideration for businesses. In terms of issues associated with this, few are more topical than factoring in sustainability. Emerging from this trend is a leasing product that deals with this directly. This product is a green lease. This not only impacts on the operations associated with a tenancy, but…
