The Eu

Data shows residential energy consumption constituting a significant portion of the overall energy end use in the European Union (EU), ranging between 15% and 30%. Furthermore, the EU’s dependency on foreign fossil fuel-based energy imports has been steadily increasing since 1993, constituting approximately 60% of its primary energy. This paper provides an analytical re-view of diverse residential building/energy policies in targeted EU countries, to shed insight on the impact of such policies and measures on energy use and efficiency trends. Accordingly, the adoption of robust residential green and energy efficient building policies in the EU has increased in the past decade. Moreover, data from EU energy efficiency and consumption databases attributes 44% of total energy savings since 2000 to energy upgrades and improvements within the residential sector. Consequently, many EU countries and organizations are continuously evaluating residential building energy consumption patterns to increase the sec-tor’s overall energy performance. To that end, energy efficiency gains in EU households were measured at 1% in 2000 compared to 27.8% in 2016, a 2600% increase. Accordingly, 36 policies have been implemented successfully since 1991 across the EU targeting improvements in residential energy efficiency and reductions in energy use. Moreover, the adoption of National Energy Efficiency Actions Plans (NEEACP) across the EU have been a major driver of energy savings and energy efficiency. Most energy efficiency plans have followed a holistic multi-dimensional approach targeting the following areas, legislative actions, financial incentives, fiscal tax exemptions, and public education and awareness programs and campaigns. These measures and policy instruments have cumulatively generated significant energy savings and measurable improvements in energy performance across the EU since their inception. As a result, EU residential energy consumption trends show a consistent decrease over the past decade. The purpose of this analysis is to explore, examine, and compare the various green building and energy-related policies in the EU, highlighting some of the more robust and progressive aspects of such policies. The paper will also analyze the multiple policies and guidelines across targeted European nations. Lastly, the study will assess the status of green residential building policies in Lebanon, drawing from the comprehensive European measures, in order to recommend a comprehensive set of guidelines to advance energy policies and building practices in the country.

Based on the theories, , and we can improve , the heat transfer resistance of retaining structure, or reduce ,the heat transfer coefficient, through the heat insulation design of outer wall, roof, ground, the door, and outer window and the thermal bridge, and finally realize the building energy conservation goals. Residential energy consumption is a important factor of China's energy saving. Exterior wall, roof, ground, the door, the external window and thermal bridge is the key parts of energy consumption of residential building.

Rural Residences

Rural residential energy consumption accounts for 46.6% of total building-related energy consumption of China. In Northeast China, energy consumption for space heating represents a significant proportion of total rural residential energy consumption and has reached 100 million tce (tons of standard coal equivalent), or more than 60% of total household energy consumption. In terms of energy consumption per square meter of gross floor area, rural residential energy consumption for heating is more than that of cities (20kgce/m2). However, the average indoor temperature of most rural residence is below 10°C, much less than that in cities (18°C). Hence, it is an important task for Chinese energy saving and emission reduction to reduce rural residential energy consumption, while enhancing indoor thermal comfort at the same time. Restricted by local technology and low economic level, rural residences currently have poor thermal insulation resulting in severe heat loss. This paper reports on research aimed at developing design strategies for improving thermal insulation properties of rural residences with appropriate technology. A field survey was conducted in six counties in severe cold areas of Northeast China, addressing the aspects of indoor and outdoor temperature, humidity, internal and external surface temperature of building envelop enclosure, and so on. The survey data show the following: 1. Modern (after 2000) brick-cement rural residences perform much better than the traditional adobe clay houses and Tatou houses (a regional type of rural residence in Northeast China – see figure A) in overall thermal performance and indoor thermal comfort; 2. Among the traditional residential house types, adobe clay houses have better heat stability and thermal storage capacity than Tatou houses; 3. Applying an internal or external thermal insulation layer can greatly improve rural residential thermal insulation properties, and is an economical and efficient solution in rural areas; 4. In terms of roofing materials, tiled roofs show much better thermal insulation properties than thatch roofs; 5. Adopting passive solar techniques can form a transition space (greenhouse) against frigid temperatures, resulting in interior temperatures 5.91°C higher than the outside surroundings. It is evident that local passive solar room design offers significant heat preservation effects and lower cost ($12/m2), embodies the ecological wisdom of rural residents, and is therefore important to popularize. The above experimental results can provide guidance in energy conservation design for both self-built residences and rural residences designed by architects. In addition, the results can also provide experimental data for energy-saving studies for rural residences in China.

Exhaust Gas Temperature

The gas boiler house is responsible for heating 308,000 m2 of residents in the community, and the historical heating energy consumption reached 3,000 tons of standard coal in 2012. The heating energy consumption index in this community is higher than that of heating energy consumption index in other residential communities. The heating system in this community is tested and analyzed comprehensively in this paper. The three aspects of heating system heat source, pipe network transmission and distribution and thermal user are combed and analyzed in this paper, to look for the energy-saving potential of each link. It is found that the exhaust gas temperature is 175℃ through the test of thermal efficiency of 2 # boiler in XX Community, and the heat loss of exhaust gas is higher. Meanwhile, it is found that the exhaust gas temperature is too high in all boilers through checking the operation record. It is found that the system water recharge is larger and the problems of leaking and aging thermal insulation layer and pipeline appear in the heating network through operation record analysis and on-site inspection. The analysis shows that there is a problem of hydraulic imbalance through the on-site test on the wall temperature of the supply pipe of the hot water supply wells in the residential buildings near, middle and far-ends. Analyze the problem existing in the heating system in XX Community, and put forward some corresponding energy saving technical proposals, such as flue gas condensing waste heat recovery, hydraulic balance adjustment and pipeline insulation improvement according to on-site survey and analysis; meanwhile, estimate the energy saving effect and the investment payback period.It is expected to realize the energy saving 728.72 tce and energy saving benefit of 1.4415 million yuan through three measures for energy saving and technicalm transformation. Estimated investment cost is 3.16 million yuan.
