It is commonly assumed that solar hot water systems save energy and reduce greenhouse emissions relative to conventional fossil fuel-powered systems. Very rarely has the life-cycle greenhouse emissions (including the embodied greenhouse emissions of manufacture) of solar hot water systems been analysed. The extent to which solar hot water systems can reduce emissions compared with conventional systems can be shown through a comparative life-cycle greenhouse emissions analysis. This method… 
Life-cycle energy analysis of domestic hot water systems in Melbourne, Australia
Solar hot water systems are seen as a viable alternative for providing hot water to households. Whilst solar hot water systems have been shown to provide savings in operational energy consumption
Evaluating the energy and carbon reductions resulting from resource-efficient household stock
The nexus of water and energy and greenhouse gas emissions is now well recognised, however, quantifying the energy savings from (hot) water-efficient technologies has been largely based on modelled
Domestic solar thermal water heating: A sustainable option for the UK?
This paper considers life cycle environmental sustainability of solar water heating systems in regions with low solar irradiation, such as the UK. The results suggest that flat plate collectors have
Economic and environmental life cycle analysis of solar hot water systems in the United States
Abstract This paper evaluates the solar water heating systems for the U.S. typical residential buildings, from the energetic, economic and environmental perspectives, and includes two different types
Life cycle assessment of domestic hot water systems: a comparative analysis
On average, hot water is responsible for 18% of residential energy consumption and corresponding greenhouse gas (GHG) emissions. Several domestic hot water systems (DHWSs) are commonly used but their
Life Cycle Assessment of Domestic Hot Water Systems : A Comparative 1 Analysis 2
10 On average, hot water is responsible for 18% of residential energy consumption and 11 corresponding greenhouse gas (GHG) emissions. Several domestic hot water systems 12 (DHWSs) are commonly used
Economic and environmental life cycle assessments of solar water heaters applied to aquaculture in the US
In life cycle costing, the use of solar water heater for aquaculture was economically favorable at any heating strategy as well as under any setting and climate, except for a 20% heating in the cold climate.
Life cycle energy (LCEA) and carbon dioxide emissions (LCCO2A) assessment of two residential buildings in Gaziantep, Turkey
Abstract Today, buildings are responsible for more than 40% of global energy used, and as much as 33% of global greenhouse gas emissions, both in developed and developing countries. In this paper, a
Energy and carbon impact analysis of a solar thermal collector system
Much research effort is focusing on the reduction of man's carbon footprint in response to global energy and sustainability initiatives. The prudence of such activities is reliant on the embodied
Comparative Energy and Carbon Assessment of Three Green Technologies for a Toronto Roof
Three different green technologies are compared in terms of net energy and carbon savings for a theoretical Toronto rooftop. Embodied energy values are calculated through Life Cycle Analysis and


Hot water tanks with a built-in water-heating coil are commonly used in district heating house stations in Denmark for domestic hot water (DHW) production and storage. In this study, an evaluation of
Using national input/output data for embodied energy analysis of individual residential buildings
Embodied energy (EE) analysis has become an important area of energy research, in attempting to trace the direct and indirect energy requirements of products and services throughout their supply
Energy used in the Construction and Operation of Houses
Efforts to minimise energy consumption in houses have now broadened to the consideration of major life cycle energy inputs. This is part of a more holistic approach to energy analysis which takes
The energy cost of goods and services
Abstract First developed for economic analysis, static linear input-output analysis has been adapted to deal with energy. This paper uses as a data-base the 1967 results of the input-output analysis
Australian energy consumption and production: historical trends and projections to 2009-10
Data on energy consumption and production in Australia from 1973-74 and projections to 2009-10 are provided. Historical and projected trends are discussed and key issues identified. All energy types,
Extracting Embodied Energy Paths from Input–Output Tables: Towards an Input–Output-based Hybrid Energy Analysis Method
Embodied energy is defined as the energy consumed in all activities necessary to support a process, including upstream processes. The Leontief inverse input-output (IO) matrix gives results that are
Net energy analysis : handbook for combining process and input-output analysis
Methods for combining process analysis with input-output analysis enables the analyst to focus data acquisition effects cost-effectively, and to achieve down to some minimum degree a specified accuracy in the results.
Input-output economics
