“…This paper was based on a real building with already had a rather compact quadratic form, therefore the building geometry was not a variable in this study even though it is well known, as found in several studies (e.g., [19,20]), that the geometry of the building has a high impact on building energy consumption.…”

Current office buildings are becoming more and more energy efficient. In particular the importance of heating is decreasing, but the share of electricity use is increasing. When the CO 2 equivalent emissions are considered, the CO 2 emissions from embodied energy make up an important share of the total, indicating that the building materials have a high importance which is often ignored when only the energy efficiency of running the building is considered. This paper studies a new office building in design phase and offers different alternatives to influence building energy consumption, CO 2 equivalent emissions from embodied energy from building materials and CO 2 equivalent emissions from energy use and how their relationships should be treated. In addition this paper studies how we should weight the primary energy use and the CO 2 equivalent emissions of different design options. The results showed that the reduction of energy use reduces both the primary energy use and CO 2 equivalent emissions. Especially the reduction of electricity use has a high importance for both primary energy use and CO 2 emissions when fossil fuels are used. The lowest CO 2 equivalent emissions were achieved when bio-based, renewable energies or nuclear power was used to supply energy for the office building. Evidently then the share of CO 2 equivalent emissions from the embodied energy of building materials and products became the dominant source of CO 2 equivalent emissions. The lowest primary energy was achieved when bio-based local heating or renewable energies, in addition to district cooling, were used. The highest primary energy was for the nuclear power option.

“…This shows that the current function estimates ownership satisfactorily for our purposes. We next estimate the region-specific UEC based on UEC data from the literature (Chen et al, 2008;IEA, 2003;Kadian et al, 2007;Mahlia et al, 2004;McNeil and Letschert, 2007;Price et al, 2006), while assuming a linear relationship between UEC and CDD and a logarithmic relationship with income UEC ¼ CDD Â ð0:865 Â lnðIncomeÞ À 6:04Þ (10)…”

“…For example, the residential electricity consumption accounted for 13.3% of final electricity consumption in 2012, compared with 10.7% in 1996 in China, per capita residential electricity is annual 459 kWh in 2012, 2 which is about ten percent of that in U.S. in 2011 (4560 kWh). 3 Current research literature concerning energy consumption in China's building sector mainly consists of two parts, one is the study on characteristics of energy consumption and carbon emissions of the building systems [2e4], defining the appropriate statistical indicators [5], or forecasting energy consumption in the phase of construction [6]. The other is to study on carbon emission from buildings during the phase of construction and operation with life cycle analysis [7e9].…”
