What are cold bridges?

A cold bridge or a temperature bridge is a section of the building envelope (end of a concrete element, wall joints, etc.) that has a reduced thermal resistance. ⠀

💢 This can be a joint between structural parts or a structural element consisting of materials with higher thermal conductivity. Such areas are cooled more strongly than other parts of the fence, so they are also called “cold bridges.” ⠀ ⠀
💦 The presence of temperature bridges significantly reduces the effectiveness of thermal protection of the building. Temperature bridges cause condensation ⠀
⠀⠀
❓ What does all this mean? ⠀
And then, dear friends, that an ideal house is a house in which there are no seams or they are very well executed. For example, the insulation is put into a run, and the connection material of the insulation with the wall is made not of metal, but of polymeric fiberglass. ⠀
⠀📍 Also, the joints of the foundation and walls are considered to be zones of the emergence of cold bridges. And also the joints of the roof. ⠀
📍 Doors, windows, loggias and balconies are also the brightest examples of cold bridges. ⠀
⠀⠀
The effects of high heat transfer ⠀
⠀⠀
💧If the room loses enough heat, condensation will form on the inner surface of the walls. As you know, dust is most attracted to such a place, so the bridge will be clearly visible even with the naked eye. Following the dust on the wall, mold and fungal microorganisms begin to develop rapidly. It is almost impossible to get rid of it, because even after painting or cosmetic repairs on the renewed surface, mold quickly emerges and worsens the microclimate of the house. ⠀
⠀⠀
Only the complete elimination of the cold bridge will help prevent its occurrence. About how to do this - in the following posts! ⠀

Victory over the Cold Bridges

Victory over the Cold Bridges ⠀

1⃣ Connection of the wall with the window and the door ⠀
They are always one of the weaknesses through which heat leaves. The thermal parameters of windows and doors are much worse than those of walls. Correct installation and sealing of the gap between windows and walls is very important. After all, you need to not only choose the right glass and frame, but also install them professionally. ⠀

2⃣ Connection of the foundation wall to the floor ⠀
The floor of the first floor in energy-efficient buildings should always be insulated, regardless of whether it is heated or not. The thermal insulation of the walls of the foundation should be connected with the insulation of the walls in a continuous layer. And the thermal insulation of the floor should be combined with the thermal insulation of the bearing wall, so its energy efficiency is higher than that of the foundation wall. ⠀
In this case, the horizontal thermal insulation will be continuous, and not even the smallest cold bridge will appear, which usually appears at the junction of the foundation walls and the ground floor..

3⃣ Connection of the external wall to the roof plane ⠀
We have already devoted a whole post to this topic. The main thing is to maintain the continuity of thermal insulation. ⠀

4⃣ Balcony plates and other constructions ⠀
Many find these architectural elements attractive and functional. And there wouldn’t be anything bad if the most popular solution was not the reinforced concrete slab on which these structures are based. Because it is in this place that a "cold bridge" of great length arises. The harm caused to them is often compared with the effect of an insulated outer wall 4-6 m long (often half the width of the house) ⠀
The solution is: this element should be completely separated from the house. The balcony slab should rest on independent pillars. And then you can use any material. ⠀

To be continued. ⠀

Освещение участка

Home and Land Lighting

We’ll start to touch upon such an important and relevant topic as lighting a house and a plot! There will be a cycle of interesting posts! ⠀
⠀⠀
At night, in the dark, wading into even the familiar areas of the site becomes difficult, and sometimes even traumatic. In addition, the decorative elements created with such trepidation and love by the owner lose their clear outlines. Moreover, at night, the territory becomes more vulnerable to attackers. Well-organized lighting of a site helps to solve all these problems at once. ⠀
⠀⠀
☝ MOST IMPORTANT OF THE LIGHTING OF THE PLOT ⠀
⠀⠀
When organizing a lighting system, it is necessary to take into account many details, so that at night the territory is safe and does not lose aesthetic qualities. The basic requirements for lighting suburban areas are as follows: ⠀
⠀⠀
💡 Lighting should be controlled in a convenient way ⠀
💡 The wiring must be safe. ⠀
It is absolutely necessary to include an RCD and a circuit breaker in the circuit ⠀
💡 all lighting elements must be designed for outdoor use, (bulbs, lamps, switches, etc.) ⠀
must be protected against moisture and dust. The cable is laid in a pipe or protective corrugation ⠀
💡 Since outdoor lighting is used every day - use energy-saving lamps ⠀
💡 It is necessary to illuminate all parts of the site, it is necessary to ensure that all the borders of the site are clearly visible ⠀
💡 The site lighting project is best done together with the landscape design project, so that later cable laying does not destroy the equipped area территорию

Types of lighting plot участка

Lighting a suburban area performs several functions at once. For each of them it is better to use a separate type of fixtures. ⠀
⠀⠀
The main types of lighting site::
⠀⠀
💡 General or functional lighting ⠀
It guarantees safe movement around the territory at night, provides light for a good rest in the evening. General lighting fixtures are primarily installed at the entrance, at the garage and at the entrance to the house. And also for lighting garden paths and recreation areas ⠀
💡 Marking site elements ⠀
A special case of general lighting. The main function of the marking light is to highlight some objects, for example, the location of the gate, the boundaries of the parking lot, steps, etc. In this case, you can use small lamps and even “luminous” stones ⠀
💡 Automatic lighting systems ⠀
Increase the security of the territory. Due to the presence of a time relay or motion sensors, one or more lighting elements can turn on when nightfall occurs or when attackers appear in the summer cottage. Similar items can also be used to scare away animals and birds by creating an effect of presence. ⠀
💡 Decorative lighting ⠀
This includes lamps that are designed to decorate and draw attention to interesting elements of the landscape rather than give full light. Such lighting is equipped with alpine hills, ponds, tree crowns, recreation areas, and for this they use LED strips, lanterns, garden figures with built-in lamps, lamps that can shine in different colors, and other elements. ⠀

Site Lighting Scheme

WE MAKE A PLOT LIGHTING SCHEME ⠀
⠀⠀
💡 Now the variety of garden lights is amazing. I would like to use literally everything on my site: decorative lanterns, backlit garden figures, and moonlight lamps, and colored lanterns to decorate the crowns of trees, and garlands, and other lighting fixtures that sometimes surprise with an unusual design. To avoid chaos in the summer cottage, it is necessary to think over the main places of the location of the fixtures in advance, determine the functions assigned to the backlight and choose the style of the lighting fixtures. ⠀
⠀⠀
📝 It is necessary to draw up a plan diagram of the location of all the lamps in the area. To do this, you can use a photocopy of the territory scheme or draw a scale plan with an indication of all available buildings. It is important to create a lighting plan in parallel with thinking through the rest of the landscape design elements. The locations of future fixtures are determined along with the design of arbors, garden paths, ponds, patios, terraces and other recreation areas. Otherwise, there is an increased risk of the possibility of redoing some of these elements due to the need to lay power cables. ⠀
⠀⠀
📍 On the diagram it is necessary to note where the fixtures will be located, how many there will be, and what function will be assigned to them, you can also specify the size and style of execution. Now an electrical wiring diagram is being drawn up: for those who are at least a little versed in electrics, this is a simple task. It is better to entrust the installation of the entire lighting system to specialists, since it, ⠀
should be as safe as possible for the owners of the site. ⠀
⠀⠀
🌟 When making a lighting plan, remember that it is imperative to highlight the entrance to the house, the gate or gate, the perimeter of the site, as well as the most dangerous places on the territory, including steps and bridges. They do not recommend doing home lighting from the fence, since a blinding effect is created in this way. When preparing a lighting scheme, it is important not to forget about the climatic features of the region. For example, the height of the fixtures should be such that under the maximum possible layer of snow they perform their functions.

Энергетическая эффективность

Energy efficiency

On April 6, 2018, the order of the Ministry of Construction of Russia dated November 17, 2017 No. 1550 / pr “On approval of the energy efficiency requirements of buildings, structures, structures” came into force. According to the order, from July 1, 2018, building projects undergoing examination should ensure a 20% reduction in energy consumption of buildings. ⠀⠀
From 2023, the required reduction in energy consumption during the design of buildings will be 40% and from 2028 - 50% relative to the base level. ⠀⠀
⠀⠀
According to experts, in order to fulfill the requirements, it is necessary to increase thermal protection by 30-100% for walls, roofs and windows. ⠀⠀
⠀⠀
⚡ A bill is already being prepared, according to which the developer will soon have to inform buyers about the energy efficiency of housing. ⠀⠀
⠀⠀
Those who believe in new technologies and rebuild, will win, contrary to all existing misconceptions. ⠀⠀
⠀⠀
Well, we can design and build: ⠀⠀
🔸 stone / brick / block / monolithic passive house with a rise in price up to 15% in comparison with the classic ⠀⠀
🔸 a passive house with an area of up to 600 m2 with a maximum electric power consumption of all engineering systems (including hot water) not more than 1.5 kW with an economically viable payback period for engineering systems ⠀⠀
🔸 a passive house, completely autonomous in engineering systems, with an economically viable payback period for engineering systems, in the absence of electrical capacities ⠀⠀

Энергосберегающий дом

Ordinary home or energy efficient?

Comparison History in Faces

The participants:
Alexey is the owner of a frame 2-storey energy-saving house (186 sq.m)
Dmitry is the owner of a house made without the use of energy-saving technologies - a timber-lined house, bricked. (152 sq.m)

💬 Alexey told us the story.

Once Dmitry went to Alexei and in a short dialogue it became clear the digital component of the monthly electricity charges.
Dmitry has a stone stove and since she can’t cope with heating, he put radiators under the windows. Its monthly expense is 8000 rubles.
⚠️ And now, attention: Alexey has not even 1,500 rubles, but 1406 for the same period!
⚠️ And this is January - the coldest month!

If you take, for example, February and March, Alexei’s consumption fell to 1200 rubles.
In November - 918 rubles. ⠀

How did our hero achieve such a result?

⠀- USP Foundation
- Warm water floor
- Proper wall insulation
- Heat storage system (1.7 cubic meters.)
- Competent orientation of the house to the cardinal points

🏰 Now imagine that you also have a stone house. Alexey compensated for heat loss (this is minus the skeleton). A building made of heat-ceramic reduces it to a maximum minimum.


> We also use a heat recovery system and a heat pump system.
> The need for their device determines the thermal calculation.

The advantages of a heat pump

An alternative source of energy as a means of reducing costs


Heat pump - what is it?

🔴 A heat or geothermal pump collects heat from the environment, converts it using refrigerant, and delivers it to the home heating system.

A pump can draw heat from three sources:
💨 Air
💧 Water
🌰 Soil

In Russia, only two of them are interesting: water and soil.

🔋 The location of the supply circuit can be horizontal or vertical (see images 1 and 2). The length (in the second case, depth) of the circuit depends on the dimensions of the heated room and the power of the pump.

✅ The main advantage of the heat pump is its high efficiency; for every kilowatt of electricity consumed, it gives about 4 kW of heat. Plus, no physical effort in the process, no waste and carbon monoxide.

When exactly do you need?

🔸 The system is mandatory for installation if you do not have a gas line or if you want to save on its connection (Favorable)
🔸 Modern models are impulse, do not work continuously, but turn on if necessary. This reduces the number of working hours per season and energy costs.
