“…Hence, a drastic reduction in global CO 2 emissions is required, which is achievable by ensuring the use of sustainable cleaner energy and a reduction in current global energy demand through improved energy efficiency [1]. The contribution of building energy use to energy-linked threats to sustainable development are varied and can include: deaths associated with indoor and outdoor air pollution, insecurity of energy resources and climate change [3]. In recent times, considerable attention has justifiably been directed towards energy savings in buildings (residential and commercial) as they account for up to 20-40% of total energy consumption in developed countries [4].…”

Abstract:Recently, considerable attention has justifiably been directed towards energy savings in buildings as they account for up to 20-40% of total energy consumption in developed countries. In the United Kingdom, studies have revealed that buildings' CO 2 emissions for account for at least 43% of total emissions. Window panels are a major component of the building fabric with considerable influence on the façade energy performance and are accountable for up to 60% of a building's overall energy loss. Therefore, the thermal performance of glazing materials is an important issue within the built environment. This work evaluates the impact of solar window films on the overall energy consumption of an existing commercial building via the use of a case study U.K. hotel and TAS dynamic simulation software. The study results demonstrated that the impact of window films on the overall energy consumption of the case study hotel is approximately 2%. However, an evaluation of various overall energy consumption components showed that the window films reduce the annual total cooling energy consumption by up to 35% along with a marginal 2% increase in the annual total heating energy consumption. They can also provide overall cost and CO 2 emissions savings of up to 3%.

Cool Marble Building Envelopes: The Effect of Aging on Energy Performance and Aesthetics

et al. 2016

Marble envelopes represent a relatively common architectural solution used in variety of historic, modern and contemporary building facades. White marble envelopes have been shown to reduce solar heat gains, while improving indoor thermal comfort and energy efficiency in summer time. While marble is useful in this context, the urban atmosphere accelerates the degradation of marble elements. This leads to changes in optical characteristics, hence the aesthetics, and affects the energy efficiency benefits offered by white marble facades. These issues are investigated in order to predict the impact of degradation on energy performance and to the aesthetic value, such as change of color and luminosity. In this study, surface degradation of white marble is analyzed by means of accelerated weathering in the laboratory while examining changes to the optical characteristics of the materials. A dynamic simulation is carried out to assess the energy performance of a building as a case study.

“…Diana et al created scenarios based on Kaya models and pointed out that energy consumption in residential heating and cooling was expected to increase approximately 79% by 2050 as compared to 2010. This figure was 84% for commercial heating and cooling [8]. King et al pointed out that the demand for more energy consumption and social electricity shortages would occur due to an increase in the world's population [9].…”

This paper focused on energy consumption and carbon emission for heating and cooling during a building's operation stage, and examined the energy effects of using Cross Laminated Timber (CLT) as an alternative building material to reinforced concrete (RC) in China's 31 key cities located in different climate zones. The authors designed two seven-story residential buildings, which were constructed with RC framed and CLT systems, separately. This was followed by simulating the energy consumption using commercialized software IES TM under the different climate zones and calculating the carbon emissions. Comparisons were made between RC and CLT systems buildings on the basis of simulation data. The results show that the estimated energy consumption and carbon emission in CLT buildings are much lower than that of RC buildings in all studied cities, which indicates that CLT systems have good potential in reducing carbon emission and saving energy consumption compared to RC. The energy consumptions and carbon emissions in both concrete and CLT buildings are closely related to the climate zones. Buildings in Severe Cold and Cold Regions consumed the most energy and released more carbon. At the national level, the estimated energy consumption at the operation stage, in the studied building with RC frames and CLT system was approximately 465.1 MJ/m 2 and 332.6 MJ/m 2 per annum, respectively. Despite vast differences in China's climate zones, the effects of energy saving and carbon reduction potentials of CLT buildings show little relationship to the climate zone. CLT buildings may result in a weighted 29.4% energy saving, which equals 24.6% carbon reductions, compared with RC buildings at the operation stage at national level, although it may vary in different climate zones.
