Beijing**Client|Reporter Jing Yiming, Zhang Shuling, Lu Yijia.
No matter how hot the heating was, the temperature in the house always hovered at 14 or 5 degrees Celsius. In the past two weeks, 12345** and the feedback received at this end have significantly increased the demands related to heating, among which the demand for room temperature is not up to standard because the wall does not have an insulation layer is more common. Some members of the public have complained that their homes are cold and damp or even frozen, and their normal life is troubled. The reporter's investigation found that the promotion of the installation of wall insulation in old buildings is facing a lot of problems, insufficient funds, different opinions, and some also involve central property rights, these factors have made the installation work in trouble.
Building 11, District 3, Xiluoyuan.
When the cold wave hits, the room temperature is difficult to reach.
My house hasn't had a room temperature of 18 since it was heated. Mr. Zhang, a resident of Building 11, District 3, Xiluoyuan, Fengtai District, reported that the temperature at home has been around 14 in the past few days, and he has to wear a down jacket at home, and he has been frozen awake when he sleeps with a two-layer thick quilt. During this winter's heating season, many residents here call 12345** or report the problem of heating in the residents' WeChat group. As you can see, the community, the property, and the heating unit have all worked hard, and some residents have even replaced the radiators, but it doesn't work at all, because the residential building has not been equipped with wall insulation.
The residents' homes have new radiators, but because the old building has no insulation, it is still very cold.
On December 15, the property and heating units of the community successively issued notices in the residents' WeChat group, saying that Beijing ushered in a big cold wave and the temperature plummeted, reminding the owners to pay attention to keeping warm. According to the "Code for the Design of Heating, Ventilation and Air Conditioning in Civil Buildings" and other relevant regulations, the minimum guaranteed outdoor temperature during the construction and design of the housing heating system is -76. According to meteorological data, the current average temperature has been lower than this temperature, which exceeds the design capacity of the heating system, and the indoor temperature of your home will be affected by the decrease in outdoor temperature. "The heating unit informs that they have continued to operate at the maximum possible capacity of the heating system.
My house is heated up with the air conditioner on, and I have to pay for the heating and electricity!For a while, in the residents' WeChat group, everyone reported their room temperature while talking about their own difficulties. Between the talks, the residents reached a consensus on the fundamental problem: "Now it is not a problem of heating is not hot, the reason for the low indoor temperature is that we do not have a wall insulation layer here, and we have been required to do it for several years, and other buildings have it, and there is no movement in Building 11." ”
The visit found that the residents who had the same troubles were not only in Building 11, but also in Building 12 next door. From the outside, the exterior walls of Building 11 are dilapidated, with a layer of bricks exposed under the windows on almost every floor. Building 12, not far away, looks much cleaner, with a bright and tidy beige façade. "Every day, we are even more anxious when we see that the building next door has been insulated with walls. In the eyes of the residents of Building 11, Building 12 has become a benchmark, but the reporter learned from the territory that in fact, Building 12 is only painted on the exterior wall, and does not do wall insulation.
The wall of Building 11 in District 3 of Xiluoyuan is not equipped with wall insulation, and the wall is mottled.
Community staff told reporters that other residential buildings in the community have been renovated a few years ago and installed insulation, because the two buildings of No. 11 and No. 12 involve central property rights units, and it is difficult to coordinate at the community level. ”
The reporter contacted the property rights unit of the two residential buildings, and a person in charge said that he had recorded the relevant problems in detail and would report them to the leaders in time to solve them.
Building 15, West District, Beili, Muxidi.
Rely on electric heaters to heat the old building and always trip.
On the evening of December 25, a thermometer was placed in every room of Ms. Wang's house, and on the evening of December 25, one showed about 13, one showed about 14, and the tallest one showed nearly 15. The reporter put his own thermometer in the coldest room on the north side and read 136℃。"The temperature has risen in the past two days, and the coldest time a few days ago, it was only 11 at home. ”
Ms. Wang, who is in her 70s, lives with her wife and children in Building 15, West District, Muxidi Beili, Xicheng District. She told reporters that the temperature at home has been substandard for more than ten years, and the last two years have been particularly cold. "I'm old, and I broke my leg again this year, and my leg hurts badly when it's cold. Ms. Wang had no choice but to wear thick cotton pants, cotton shoes and woolen socks at home, and turn on an electric blanket and fill a hot water bag when she slept.
The gas water heater in my house was frozen and cracked. Mr. Chen, who lives on the third floor of the building, has also been plagued by heating problems for many years. It is understood that Building 15 is a high-rise tower, with a total of 112 households, some of which are all facing north, and Mr. Chen's house is this type of house. "Usually the bedroom is only fifteen or sixteen degrees Celsius, and the kitchen is the coldest, only 6 a few days ago. Mr. Chen said that when he was at work, he suddenly received a ** from a neighbor, saying that the house was running out of water, and he hurried home to find that the gas water heater installed in the kitchen was frozen and spraying water.
Even more of a headache for residents is the frequent power outages caused by heating. Ms. Zhang's family has elderly people in their 80s and children who are going to school, and usually relies on electric heaters to keep warm at home. Recently, Ms. Zhang woke up in the middle of the night and found that there was a power outage at home. "The heating is not hot, the electric heater is not working, I shivered and wrapped in three layers of quilts all night, and I couldn't sleep in the cold. Ms. Zhang said that because the problem of heating in the building is very common, many residents rely on high-power electrical appliances such as air conditioners and electric heaters to keep warm, but this building is an old building built for more than 30 years, and too many high-power electrical appliances are turned on at the same time, which is easy to trip and lose power. "In the evening, when everyone comes back from work, all kinds of heating appliances will be turned on, so tripping always happens at night. It's been four nights of tripping power outages recently. ”
Why is it so cold in the residents' homes?The staff of the heating unit explained that the old building does not have a wall insulation layer, and it is also located at the end of the pipeline, coupled with the aging of radiators in some residents' homes, the lack of window sealing, etc., which leads to a variety of reasons that cause residents to not warm their homes. "Our thermal power station is currently running at full capacity, and all the valves are open, although the lack of warmth is caused by many reasons, but the main reason is that there is no wall insulation. ”
The reporter visited more than a dozen households in a row, and everyone tried their best to keep out the cold. Most of the residents have double-glazed windows, some residents have replaced the radiators a few years ago, and some have put seals on the security doors and padded curtains on the balcony doors in order to retain the little heat. In order to enhance the tightness, she sealed the west-facing bedroom windows with thermal insulation cotton to enhance the seal.
The reporter learned from the territory that the current plan to install wall insulation layer in the building is difficult, and the main reason is that it involves the central property rights unit. Half of the building's more than 110 households are elderly, some in their 90s, and residents are eager to find a way to warm up the building.
Lianshui Yiyuan Community.
The phenomenon of "cold bridge" exacerbates the hypothermia of old buildings.
The problem that there is no wall insulation layer in the first and second phases of Lianshui Yiyuan Community in Tongzhou District has plagued residents for many years. Some time ago, the snow cooled down, and the residents felt more deeply how cold it was in the house. In the WeChat group, everyone is posting the readings of their own thermometers every day, from 17 to 14, each saying their own suffering, and the residents are looking forward to it.
In the Lianshui Yiyuan Community, the high-rise buildings and slab buildings are presented in a stepped design, although they are beautiful, but because there is no wall insulation layer, it has brought a trouble - the "cold bridge" phenomenon. Part of the same wall is the interior wall of the room, and part of it becomes the exterior wall. In the severe winter, the alternation of cold and heat on this wall is obvious, and the wall is constantly seeping condensation, sitting in the residents' homes, you can obviously feel very wet and cold, and some residents' balconies and kitchens even freeze.
On December 22, in a resident's house in Building 1 of the community, the reporter saw that the window frame of the kitchen and the surrounding wall were covered with a thick layer of ice, and even the windows could not be opened, and the residents had to wear down jackets and cotton pants for cooking. At this time, in the living room, the two children were watching TV, and they were also dressed three layers inside and three layers outside. The thermometer on the table showed that the living room temperature was 169℃。The resident said that now the child sleeps with himself at night, and the child's bedroom is too cold, "I have been sick twice this winter, and the house is clammy and cold, I am really afraid that they will be sick again." ”
In addition to the six-storey residential buildings, there are also high-rise buildings in the community, and the residents there are plagued by the same problems. In a resident's house on the 12th floor of Building 8, the bedroom is the coldest, and as soon as you enter the house, you feel a chill seeping through the east wall. Residents said that in the past half month, they have often been awakened by freezing at night. The reason for this is that the resident's house is on the top floor of the unit, but the top floor of the next unit is only 11 floors. Under this staggered design, the east wall of the resident's house became the exterior wall. Residents said that not only is it cold, but the problem of dampness and mildew on the wall is also very serious.
We are all looking forward to the installation of insulation in residential buildings to solve the problem of indoor dampness and coldness. On the day of the reporter's visit, residents generally put forward this demand. Residents said that the funds needed to install wall insulation are not a small number, and the problem cannot be solved for many years, mainly because it is stuck in money.
This year, through small and micro renovation projects, the territory has replaced a lot of outdated equipment and facilities in the community, and also built roads. Some residents asked whether they could apply for funds to install wall insulation through this project, but it turned out that the funds that could be applied for through related projects were only a drop in the bucket for the installation of insulation. We have also considered solving the problem through public maintenance funds, but the public maintenance funds in the community have bottomed out, and if they are used, it may involve supplementary money, and it has become difficult for residents to agree on their opinions. "We also checked the relevant policies to see if the comprehensive renovation of the old community could solve the problem, and it turned out that we are a community after 2000, and I am afraid that we will not be able to accept it in the short term. ”
The reporter learned from the territory that the Lianshui Yiyuan community has replaced the heating unit this year, and the first year of trial operation of the equipment may have an impact on the heating of the community, and the equipment has been debugged. After receiving the residents' complaints, the community staff have to go to the boiler room every day to supervise the operation of the equipment, and at the same time, they have been urging the heating unit to try their best to solve the problem of unheated residents' homes. If it is really impossible to solve the problem, the community requires the heating unit to take the initiative to communicate with the residents to reduce or reduce the heating fee.
Regarding the installation of wall insulation, the relevant parties have also been thinking of ways. Judging from the current situation, it is indeed difficult to support the public maintenance funds of the community. The public maintenance funds of Lianshui Yiyuan community are charged according to 2% of the purchase price, compared with now, the overall housing price of the community in 2003 is low, and the amount of public maintenance funds collected per household is relatively small, and the total amount is difficult to support the funds required for the installation of wall insulation projects.
