It is estimated that over 50% of the world’s population now lives in cities. According to the UN Habitat, that is set to rise to 60% within a couple of decades. Cities are responsible for around 65% of all energy used and 70% of all greenhouse gases produced worldwide. The exponential increase in population, and contemporaneous increase in standard of living for many, will mean that the demand for essential goods and services will increase substantially.
In many fields the limits of what Earth can sustain have already been reached (Fokkema 2007). While there is an exponential growth in population, there is decline in the necessary resources to sustain this population. The key challenge of the 21st century is to redefine the way resources are being consumed and find sustainable solutions to treat materials and energy resources.
The building sector accounts for 50% of global greenhouse gas emission (UNEP-IETC, 2002) which makes it the largest single contributor to greenhouse gas emissions globally. In many countries the construction industry accounts for up to 40% of materials entering the global economy (CIWMB 2000), 50% of waste production, and 40 % of energy consumption. Materials used for buildings will have an impact on building energy consumption, but also on reuse and recycling potential of buildings.
Energy use is a widely used measure of the environmental impact of buildings. Operational energy is the first that needs to be tackled; however, as buildings are becoming better isolated and ever more renewable energy sources are being used, embodied energy has gained additional focus. Buildings use energy throughout their whole life cycle from construction to the end. Studies on the total energy use during the whole life cycle of the building are necessary, in order to identify strategies for energy reduction and its circular flows through the built environment.
This amplifies the need to look into all energy flows throughout the building phases. The life cycle analyses of energy flows have become essential in order to provide an integral view of the energy impact of the building sector on the environment.
This Special Issue aims at addressing the many inter-related aspects of the life-cycle energy analysis of buildings, including green energy strategies for energy positive buildings, CO2-balanced building, life cycle design of building, life time building energy, bioclimatic design and evaluation methods that guide the design and decision making process towards achieving green buildings and built environment.

Title: An Integrated Approach to Emergy and Environmental Accounting of Buildings
Author: RS Srinivasan
Affilication: M.E. Rinker, Sr. School of Construction Management, University of Florida, USA
Abstract: Through comprehensive assessment of buildings and its components during all building stages, life cycle energy analysis attempts to provide a holistic view of the impact to the environment. Recently, in the U.S., green building rating systems have evinced strong interest in such assessments through allocating points and, in some cases, making them a required component to secure building rating. Similar to the exponential increase in the awareness of building energy modeling and the tools that support such activities, it is expected that the building life cycle energy analysis and the limited number of tools that support such assessments, will be excessively used. Although designers are empowered with such tools to amass credits towards their green rating, this may act as a double-edge sword – on one hand, the benefits are enormous considering that previously rating systems focused predominantly on operational energy use, while on the other hand, it poses two significant problems: (1) the lack of knowledge of the tool, i.e., the deficiency in understanding the underlying constructs and the various assumptions used in such tools, and (2) the assumption that raw materials are given to us in plenty and that they do not deplete, i.e., none of the tools except a very few approaches consider the energies used up in the formation of such raw materials. This paper addresses the later issues for both widespread uses of life cycle energy analysis tools and to extend the life cycle energy analysis to raw material formation stage.
The first part of paper provides a detailed discussion on the various types of life cycle energy analysis tools, particularly the sector-based (EIO-LCA), process-based (Athena® Impact Estimator, SimaPro, GaBi), and the use of a hybrid-approaches (BIRDS). Besides, the discussion will expand to include the energy used up in raw material formation through the introduction of the concept of emergy (and Eco-LCA). The second part of the paper introduces a novel decision support tool developed with an integrated approach to emergy and environmental accounting of buildings. This tool allows a single input (material quantities) and provides a series of outputs through its in-built database. The outputs include sej (using emergy transformities and Eco-LCA), total energy in TJs and emissions such as SOx, NOx, CO2, etc. Through aggregation, several midpoint indicators (GWP, ODP, Disability Adjusted Life Years or DALY, PDF) and including carbon sequestration, human health and age impacts are determined. Using this integrated emergy and environmental accounting approaches, this tool will aid design professionals with a clear understanding of the sustainable choices at hand at a very early stage in the design process.

Title: Some of the advantages of natural renewable materials in the building sector

Abstract: Architecture design today has become far more challenging than it traditionally used to be. On top of accustomed thermal insulation thickness and heating demand, architects need to design new or renovate existing structures in compliance with the primary energy demand, CO2 reductions, as well as ecological properties of the building materials. These properties are essential for a holistic assessment.
Researches and demand for ecological building materials have been growing dramatically, particularly for insulating materials from renewable resources. Conventional design, constructions and conventional materials are still predominantly used in the world, particularly in Bosnia and Herzegovina and Turkey.
The aim of this paper is to present a comparison between the use of conventional methods, constructions and materials against alternative solutions of renewable insulations materials application in wall constructions. Conventional walls are predominantly made of cement, bricks, Styrofoam, plaster and paint. For innovative walls, materials used for a wall 1 are: brick, wood fibre insulation, plaster, coat render, and for wall 2: timber, sheep’s wool insulation, brick, OSB board and plaster. The test results indicate the amount of primary energy and CO2 emission that could be saved if renewable materials are used not only for insulation but for the construction as well. Findings also show great demand for a new clean technology in brick production that will save energy and CO2 emission. Our findings also show that renewable materials have more ecological advantages and present fewer health risks.
