“…Sartori and Hestnes (2007) conducted a literature survey of the total life-cycle energy use of 60 different buildings (both residential and non-residential) from nine different countries. They focused on gathering information on the total embodied energy and operating energy of these buildings (no data was collected on GWP).…”

“…The majority of buildings that were surveyed were either residential or office buildings. From their literature review, they concluded that despite climate and other differences between the case study buildings, a linear relationship between operating energy and total energy was found (Sartori & Hestnes, 2007). In other words, the operating energy of a building has the single greatest impact on the total life-cycle energy of a building.…”

“…Sartori and Hestnes (2007) also discussed one of the systemic problems with the literature dealing with the LCA of buildings. In their literature review, Sartori and Hestnes (2007) found that there was a wide variation in how the data was presented from one study to the next. For instance, the 60 case study buildings that they looked at, all varied in terms of their lifespan, whether energy data was presented in terms of secondary or primary energy, whether only the initial embodied energy or total embodied energy was calculated, and whether end-of-life effects (such as recycling) were considered.…”

In North America, the operation of buildings accounts for approximately one third of the total energy use and greenhouse gas emissions annually. Office buildings are responsible for roughly 35% of the total commercial/institutional secondary energy use in Canada, followed by retail buildings at 17% (NRCan, OEE, 2010).In recent years, a number of researchers from around the world have conducted life-cycle assessment (LCA) studies to investigate the impacts of buildings on the environment. Most studies have focused on three types of buildings: office buildings, single residential dwellings, and multi-unit residential apartments. There have been almost no comprehensive LCA studies of retail buildings, specifically single-storey retail buildings. This is a problem, since compared to office buildings, single residential dwellings, and multi-unit residential apartments, retail buildings consume approximately 1.2, 2.0, and 2.3 times more energy per floor area respectively (NRCan, OEE, 2010). In addition, retail buildings usually undergo major resource intensive renovations far sooner than other building types. Therefore, the primary goal of this study was to conduct a comprehensive LCA for the components of a singlestorey retail building located in Toronto, Canada, to determine which building components contribute the most towards the total life-cycle energy use and global warming potential (GWP) after 50 years.Using the latest LCA techniques, the total life-cycle energy use and GWP was calculated for 220 different building components including: exterior infill walls, roofs, structural systems, floors, windows, doors, foundations, and interior partition walls. Also, a comprehensive LCA study was conducted for five single-storey retail buildings (including a pre-engineered steel building system which is lacking in the literature), in order to determine which components of a single-storey retail building are responsible for the most environmental damage.For a typical single-storey retail building located in Toronto, Canada, the operating energy (and GWP) accounts for about 91% (88%) and the total embodied energy (and GWP) accounts for about 9% (12%) of the total energy (and GWP) after 50 years. The roof alone is responsible for nearly half of the total embodied energy and GWP of the entire building. The LCA study also found that after 50 years, the total energy (and GWP) of the five case study buildings only differed at most by 6% (7%), regardless of the choice of structural system, or whether the building was made predominately of steel or wood building components. This thesis concludes with a prioritized list of recommendations for reducing the total life-cycle energy use and GWP of a single-storey retail building in Canada.iv

“…Other factors that affect the service live of a building include climate, design, ease of maintenance, construction type, age, workmanship and relationship between embodied energy and life cycle energy). A commonly assumed service life of buildings is a 50-year period [20] although in some cases, service life is chosen as a 40-year period [19].…”

Models which fully evaluate the life cycle energy and greenhouse gas (GHG) emissions of national housing stocks are not reported in literature. Capturing a holistic view of energy and emissions of the residential sector is an important process that can lead to a more effective policy making. This paper presents a methodology which evaluates the life cycle energy and GHG emissions of retrofitting housing stocks considering all life cycle stages and incorporating, to the greatest extent possible, all upstream inputs.To achieve this, we developed a hybrid model of the existing Irish housing stock, comprising a process-based approach supplemented by input -output LCA for installation of materials and fit-outs and maintenance of appliances. Life cycle analysis (LCA) is a commonly accepted technique for evaluating cradle-to-grave environmental impacts of a product. Using an assumed 50-year life span in all cases, representative archetypes were used to estimate the performance along retrofitting, operation, maintenance and disassembly phases of the three selected house retrofit scenarios: BaseCase (no intervention), Current Standards (retrofitting to meet existing building regulations) and Passive House (retrofitting to meet Passive House Standards).Results show that detached houses displayed the highest range of life cycle energy and exhibited the greatest absolute and percentage reductions compared to other house types, as life cycle energy ranges from 386 -614kWh/m 2 .yr, 225 -261kWh/m 2 .yr and 126 -137kWh/m 2 .yr for all house scenarios, respectively. Using these results an assessment is provided for policy makers on a holistic view of the life cycle performance of existing dwellings.
