Building energy systems and the use of energy in an institution, (The University of Canterbury's Ilam campus) are .investigated in this report. The existing installed systems are analysed and alternative "State of the Art" building energy systems are investigated. While technical and economic factors are the main criteria by which these systems are judged, commercial acceptability in New Zealand has also been a major concern. Section 1 details existing campus building energy systems. Section 2 examines the following alternative systems: 1. Peak Shaving of electrical demand peaks, is compare

Abstract:

The UK Government has set the target of reducing CO2 emissions by 60% by 2050. Energy used by buildings is presently responsible for around half of C02 emissions in the UK. There are many established methods for reducing such emissions from building operation but these opportunities are not being seized to their full potential. One of these methods is the use of Alternative Energy Technologies (AETs) integrated into the built environment. Engineering consultants have a key role in the design of buildings, their energy consumption and the consideration of AETs. The objectives of this thesis are

The development of technologies and structures providing energy for household use in South Africa have for many years been dominated by the needs of "white" households.

Thus, for roughly two-thirds of the population in South Africa, the struggle to meet basic energy needs for cooking, water heating, space heating and lighting is time consuming and expensive.

Legally binding targets set by the UK government to reduce carbon emissions by 2050 mean it is imperative that the efficiency of the UK housing stock is improved. Housing currently contributes over 30% of the UK s total carbon emissions and a large proportion of the current stock will still exist in 2050. There is therefore a need to retrofit this existing stock with energy saving measures, as the savings from new builds will not be adequate to meet the stringent carbon reduction targets.

Once a WSN is deployed, sensor nodes must self-organize and live as long as possible, based only on their initial amount of energy.

The project that is presented in this report is the result of a master thesis for the Industrial Design Engineering programme at Luleå University of Technology. The project was conducted towards and together with the company Leosol during the fall of 2020. For the past couple of years, Leosol has invested time and money into online advertisement. Their advertisement generates a greater visit flow onto their website; however, it rarely produces any bookings of their services. Leosol wants to increase the number of bookings done through their website. This master thesis is conducted to contribu

Abstract:

Die Einführung neuartiger Energietechnologien wird allgemein als der Schlüssel zur Senkung klimaschädlicher Treibhausgase angesehen. Allerdings ist die Abbildung derartiger Technologien in numerischen Modellen zur Simulation und ökonomischen Analyse von energie- und klimaschutzpolitischen Maßnahmen vielfach noch rudimentär. Die Dissertation entwickelt neue Ansätze zur Einbindung von technologischen Innovationen in energie-ökonomische allgemeine Gleichgewichtsmodelle, mit dem Ziel den Energiesektor realitätsnäher abzubilden. Die Dissertation adressiert einige der Hauptkritikpunkte an allgemeine

Abstract:

In Sweden, buildings are responsible for about 40 % of total energy use and about 10 % of total CO2 emissions Today more than 60 % of existing Swedish residential buildings are over 40 years old and are in need of major renovation. In addition, 15 % of all multi-family buildings and 27 % of all single-family houses were built before 1945. The increased energy use and threat from CO2 emissions of the building sector create a need for energy efficiency. The important role that renovation of residential buildings will play in reducing the total energy used by the Swedish building sector as well a

Abstract:

In recent years, the excessive emission of greenhouse gas CO2, it causing globalwarming, already poses a serious threat to human survival. The problem catches theattention all over the world, and promoting the development of building energyefficiency. In order to the sustainable development of human beings, in 1992 theUnited Nations framework convention on climate change (UFCCC) organizationpublished the Kyoto protocol. In the Kyoto protocol, the European countriescommitted that during 2008 and 2012 they would reduce the amount of greenhouseemissions to 8% compare to 1990.[2] Building envelope

AquaVillas CasaBona väggsystem innehåller i dagsläget isoleringsmaterialet EPS, vilket har visat svagheter vid brand. Målet med denna studie var att föreslå ett alternativt isoleringsmaterial till EPS med hänsyn till brand, energianvändning och U-värde, samt energiåtgång och koldioxidutsläpp vid tillverkning. Syftet var att det föreslagna alternativa isoleringsmaterialet skall kunna användas av tillverkare i väggprodukter som ett alternativ till EPS. I denna studie undersöktes fyra olika isoleringsmaterial genom kritisk granskning av vetenskapliga artiklar och litteratur, samt genom fältstudie

Abstract:

Purpose: Villas built before 1960 represent around 45% of the dwelling in Sweden. Since the average U-value in their walls is around 0,5 W/m2K, there is a great concern to improve these values. The Swedish government's goal is to reduce energy intensity in the country by 2020 by 20 % from 2008’s values. The aim of this study is to reach phase renovation proposals taking into account energy and moisture on houses consisting of standing shelves. With this, the authors wish to contribute and encourage renovation of existing villas, which in turn can lead to reduced energy consumption. Method: Th

Vid ändring av äldre bebyggelse som är det viktigt att beakta de kulturhistoriska och arkitektoniska värdena. Vid ombyggnation till bostäder och energieffektivisering är det viktigt att detta genomförs varsamt på äldre värdefull bebyggelse. Syftet med arbetet är att bidra till en ökad förståelse för hur en äldre byggnads arkitektoniska och kulturhistoriska värden kan bevaras trots att det sker en funktionsändring från en verksamhet till en annan.
