《建筑工人》向全国公开发行了。我谨向广大读者表示祝贺,向编辑部的同志们表示支持。借此机会,我愿和广大建筑工人,建筑界人士谈谈节约能源的问题,希望引起普遍的关心和重视,共同做好这项工作。目前,国际上普遍发生能源危机。我国的能源供应和开发也存在紧张状态,甚至已影响到工农业生产的正常发展。根据国内专家估算,我国能源储量总数虽不小,但按人口平均计算,仅是国际人口平均数的一半,而且开发所需时间也比较长,非一、二年所能解决。在五届人大三次会议上,姚依林副总理针对我国能源情况,提出“实行能源的开发和节约并重,近期要把节能放在优先的地位,大力开展以节能为中心的技术改造和结构改革”。并说“大力开展以节能为中心的技术改造。这是今后一个长时期的节能途径,也是向工业现代化前进的重大步骤”。在现代化的国家中,建筑物耗用能量要占国家总耗能量1/5～1/3。房屋围护结构绝热性能的好坏,会很大地影响为保证房屋必要的生产和生活条件所必需的耗能量。去年我在访法期间,参观了里昂的一所3万平方米的市政管理大楼,由于设计上合理采用围护结构材料和构造技术,施工严密,在充分利用室内设备余热和人体散发热量等情况下,据介绍整个建筑在-3℃气温下,就能做到不另加能源,保证室内必要的舒适温度。反之,设计选材和构造不合要求,施工粗糙,会使房屋散失大量室内热量,增加采暖保温的能源消耗。我们目前还短缺足够的价廉物美的保温隔热材料,建筑标准偏低,有些要求还难以做到。但如果能在设计构造和施工上重视围护结构的密闭程度,也会大大提高房屋保温隔热性能。窗户是走失热能的重要部位。北方生活习惯每到冬季往往要在窗 The “Construction Workers” was publicly distributed to the whole country. I would like to congratulate the readers and express my support to the comrades in the editorial department. To take this opportunity, I would like to talk with the majority of construction workers and construction professionals about the issue of energy conservation. I hope to arouse general concern and attention and do a good job in this work. At present, there are widespread energy crises in the world. China’s energy supply and development also have tensions, and have even affected the normal development of industrial and agricultural production. According to estimates by domestic experts, although the total energy reserves in China are not small, they are only half of the average population of the international population, and the time required for development is relatively long. It can be solved in one or two years. At the Third Session of the Fifth National People’s Congress, Deputy Prime Minister Yao Yilin proposed “implementation of energy development and conservation, focusing on energy conservation in the near future, and vigorously carrying out energy-conservation-oriented technological transformation and structural reform” in response to China’s energy situation. “. They also said that ”vigorously carrying out technological transformation centering on energy conservation is a long-term energy-saving approach and a major step toward industrial modernization." In a modern country, buildings consume 1/5 to 1/3 of the country’s total energy consumption. The insulation performance of the building envelope will greatly influence the energy consumption necessary to ensure the necessary production and living conditions of the house. During my visit to France last year, I visited a 30,000-square-meter municipal administration building in Lyon. Due to the rational design of the building envelope material and construction technology, the construction is tight, and we make full use of the residual heat of the indoor equipment and the human body to dissipate heat. Next, according to the introduction of the entire building at an air temperature of -3°C, it can be done without additional energy to ensure the necessary comfortable temperature indoors. On the contrary, the design of materials and structures are not satisfactory, and the construction is rough, which will cause the house to lose a lot of indoor heat and increase the energy consumption for heating and insulation. We are still short of adequate and inexpensive thermal insulation materials. Construction standards are low and some requirements are still difficult to achieve. However, if the degree of containment of the enclosure structure can be taken into consideration in the design, construction and construction, the thermal insulation performance of the house will be greatly improved. Windows are an important part of losing heat. The habit of living in the north is often at the window every winter
