In this article we will get acquainted with technical devices that save energy, heat and water in rooms. By installing this equipment in educational institutions, you will find solutions to energy efficiency problems. Simple, like the school “twice two.” But they are a guarantee of savings.
Before we talk about these important energy-saving devices, a few words about meters. After all, they can rightfully be considered one of the specific measures to increase energy efficiency. Educational institutions will benefit a lot if they put savings on water, electricity, heat and gas on the meter. With their help, unnecessary energy resources are not consumed, and you will have to pay less for what you use. Each meter is beneficial in terms of savings - utility bills are reduced by at least three times. And that's without taking into account that important fact that any meter installed in an educational institution pays for itself quite quickly.
Energy-saving glass is the first and, perhaps, main protection against heat loss. A special thin coating on the glass allows visible light to pass through and retains thermal radiation. Energy-saving double-glazed windows have many undeniable advantages:
Heating equipment also contributes to energy saving. The newest in this regard are considered bimetallic radiators, which effectively replace old cast iron batteries, which cannot be cleaned. Such radiators are durable and sealed. The strengths of such heaters are obvious:
We saved energy, but how to increase it? When the temperature outside is below -20C, you cannot do without electric radiators. Here are their convincing advantages:
Replacing incandescent lamps with fluorescent and LED lamps lighting on average saves about 5 thousand dollars per year for a regular high school. In addition to such significant energy saving indicators, another important factor is the latest equipment. Modern lighting devices protect our health.
Engineering solutions for new lighting equipment are simple and do not require large expenses; they quickly pay for themselves due to a reduction in energy consumption by 30-80%.
Let us dwell in more detail on the properties and advantages of energy-saving lighting equipment - in particular, fluorescent lamps:
However, after such a lamp burns out, under no circumstances should it be broken or thrown away. A huge disadvantage of fluorescent lamps is their additional disposal after the end of their service life, because... they contain mercury.
LED lighting is the most promising source light at the moment, largely due to its energy efficiency and other strengths:
The use of a whole army of electrical appliances in educational institutions leads to network overloads, which can cause short circuits. Electrical wiring installation standards have long been outdated, and the time has come to install modern protective equipment. The solution is simple - the electrical distribution networks are being reconstructed and their capacity is being increased.
Modern relays save energy by allowing you to use multiple electrical appliances without creating loads. The operating principle of such a relay is simple. When the total power of electrical appliances in use exceeds the standard, one or more non-priority appliances are turned off. For example, if it is important to use sockets to power computers, then other devices will automatically be disconnected and connected. At the same time, we will not feel any discomfort and will insure the network from loads.
Energy saving includes not only the conservation of heat, but also water, because a lot of electricity is spent on its delivery. A faucet with a photocell is the best thing people have come up with to save water to date. Using a touchless faucet costs 6 times less than a traditional faucet. less water. It does not have a valve, but the mixer works regardless of this when you bring your hands to it. The source is “hidden” in the case infrared radiation and a photocell that receives the beam. We bring our hands to the tap, and they fall into the field of view of the photocell. Therefore, the electronic device instantly “reacts” and turns on the water. Economical, convenient and hygienic.
Climate control systems of buildings consume a significant amount of energy resources, which ultimately affects operating costs; many different energy-saving schemes have been developed to reduce these costs. Often the main way to save is to combine systems, excess heat from one system is transferred to another, or equipment is initially designed with low energy consumption or using renewable resources, or resources of lower cost.
Almost everything can be included in this category. modern equipment, because technologies are developing, and the energy efficiency class is regularly being raised, so simply replacing existing equipment with newer and more economical ones is already one of the ways to save energy.
This type of equipment includes solar, wind and earth energy, in the context of our systems this is the use of solar collectors for hot water supply and heating systems, as well as the use of geothermal heat pumps with ground collectors. Such equipment, of course, consumes not only green energy, but also electricity, but it is used mainly for energy transfer, and not for creation. For example, in solar collectors electricity is only needed to operate the pumps and automation system. In the case of a heat pump, electricity is also spent on heat generation, or, more precisely, on conversion, but it is used much more efficiently, and if you use a ground collector for cooling, you can really only get by with electricity to operate the pump to pump water. Our sewerage system design company, ventilation, heating and other engineering systems, thanks to a variety of designed and installed projects, has accumulated significant experience in the use of combinations of various resources and equipment for all building engineering systems.
This type of equipment can include solid fuel boilers, since it is cheaper than gas, or the use of heat pumps and even the use of electricity as the main source of heat, while the electric boiler operates at night at a cheap rate and heats the storage tank, which is consumed during days when the electricity tariff is higher.
In heating systems, you can save by using and combining various heat sources, such as a heat pump, solid fuel boiler and even solar collectors. The essence of the systems is that the equipment has its limitations, and when, for example, it is too cold for the air source heat pump to operate, another system could be switched on. In the case of a solid fuel boiler, whose power control system is not very flexible, it is possible to use a storage tank to accumulate excess heat during combustion and use it the rest of the time, and in case you forgot to add fuel, there is always a gas or other boiler in reserve . The greatest efficiency can be achieved in the heating segment of private residential buildings and cottages. By combining heat sources and using energy prices, you can achieve significant savings; you can do this manually, or you can rely on automation systems; a number of different weather-dependent controllers have been specially developed for this. Controller sensors are installed in the return pipeline, in the supply pipeline, outdoors, indoors, and a control signal is also supplied to the three-way control valve of the system and to the boilers. Receiving information from all sensors and sending regulatory signals to the actuators, the controller controls the operation of the system according to configured algorithms.
There are not many energy-saving technologies that can be used in air conditioning systems; the most efficient systems are ground collectors, but they are mainly suitable only for small buildings with the availability of land for the device. Thus, the most efficient systems can be used mainly in the niche of cottages and private country houses. But not everything is so bad, you can save money in air conditioning by using intelligent systems, in particular, multi-zone systems are the most effective; thanks to a large range of power control, weekly programs and effective regulation, systems of this type can significantly save energy. In energy saving systems, it is also possible to use the condensation heat of outdoor units technical refrigeration equipment and use it to heat water DHW systems or other production needs.
Heating and cooling air consumes a lot of resources and throws it away exhaust systems to the street is not very effective, so ventilation was developed air heat exchangers– recuperators. Efficiency supply and exhaust systems with a recuperator it can reach 75%, depending on the type of recuperator. The essence of the work is heating and cooling supply air, supplied to the room, due to the removed exhaust. The use of frequency controllers and various sensors can also reduce energy costs by reducing the volume of air during non-operating or part-load operating hours.

Experience in implementing energy efficiency requirements for electrical equipment
Many years of investment in building capacity in IEA member countries have provided most of them with a strong foundation for introducing minimum standards energy efficiency(MSEE) and mandatory energy labels that are the cornerstone of national strategies energy efficiency.
Energy efficiency is the rational use of energy resources. In energy-efficient buildings, less electricity is consumed, but the level of energy supply to the building remains the same. If we compare this term with energy saving, then its difference will not be saving energy, but its efficient use, without harming consumers.
Energy-efficient devices can be located in every engineering system of a building and optimize its processes - heating, ventilation, electrical equipment, electric lighting and even energy supply; the main rule is to rationally consume and produce energy. The goal of energy efficient projects is to create a comfortable, optimized and automated environment for people in a building, energy saving and, of course, efficient energy consumption.
For effective use energy resources, different technologies are being introduced:
Important components of an energy-efficient project are innovative and energy-saving technologies aimed at:
The most important factor in an energy efficient project is to be considered, not only to optimize and automate everything engineering systems separately, but also to create a unified multifunctional dispatch system for automatic and manual building control.
An energy efficiency passport is a special document issued on the basis of an inspection of the engineering and energy systems of a building. In existing buildings, the purpose of obtaining it is to find possible ways to save energy to improve energy efficiency. In new buildings the passport is mandatory document to obtain permission to put the facility into operation. The passport contains information about:
Let us dwell in more detail on the use of energy-efficient devices in lighting systems
A large share of the energy used by buildings is spent on lighting needs. In the world, 19% of energy resources used go to the needs of artificial lighting. Therefore, by using energy-efficient devices, you can achieve:
For a comparative assessment of traditional and energy efficient system lighting, we present the following economic calculations:

Annual costs in car parks for lighting consumption are 9.82 kW. and using traditional lighting systems are 387,104 rubles, and when installing an energy-efficient and automated lighting system they will be 129,034 rubles.
In hotels, with lighting consumption - 4.3 kW, without automation of lighting for the year you will need to pay 169,506 rubles, and when using a control system - 70,627 rubles.
The steps to improve the energy efficiency of a lighting system are:
At the first stage, in existing buildings, it is possible to seek help from specialized agencies on improving energy efficiency in general, if the question concerns only the lighting system, our specialists are always ready to go to the site and collect the necessary data for developing the project. In new buildings, energy-efficient equipment must be used at the design stage, so that at the construction stage all the necessary communications have already been laid, this significantly reduces the implementation time and quality of energy-efficient solutions, our specialists are always ready to help designers with the arrangement of equipment and complete technical support project, of any complexity.
At the second stage, according to the data obtained after inspecting the facility, the most energy-efficient rooms and rooms where automation can significantly save energy are selected. Next, work is carried out to develop the concept, which includes the selection of equipment for different types premises, placement of energy-saving equipment in the project, drawing connection diagrams and developing algorithms for equipment operation.
At the third stage, based on the data collected during the inspection of the facility and after choosing a concept with the arrangement of equipment, an energy efficiency calculation is created, which collects all the information on current state lighting systems, and most importantly it contains detailed information on improving and optimizing an existing or planned lighting system to improve the energy efficiency of a building.

Automation of the lighting system makes it possible V environment, by reducing consumption. Installation intelligent systems for monitoring and control of lamps, as well as motion, presence and light sensors that control lighting depending on daylight, will save up to 70% of the funds allocated for energy consumption.
To our blog so as not to miss useful materials about lighting automation and energy efficiency.
Energy efficiency of equipment implies the use in production and in everyday life of devices that consume less energy resources to achieve performance indicators or even improve them compared to conventional equipment.
Increasing the energy efficiency of equipment in enterprises is an important and economically feasible, but so far little-used way to increase the profits and competitiveness of an enterprise. It can be confidently stated that increasing the energy efficiency of equipment will allow industries to more successfully overcome dependence on energy resources, not be afraid of unreliable energy supplies, compensate for rising prices and increased energy bills, and also reduce damage to the environment and health.
Why does the introduction of technologies that increase the energy efficiency of equipment obvious benefits Is it quite slow? There are several reasons for this. First of all, conservatism. It takes some time before something new becomes fashionable and then habitual and obligatory. Another reason is the lack of awareness of the population in the field of energy efficiency of equipment. For example, unfounded claims about the dangers of fluorescent lamps force consumers to avoid purchasing them, although objectively there are no reasons for this. The next factor is price. It is of great importance, because, at first glance, the costs of new equipment are prohibitively high. But an economic calculation of investments in improving the energy efficiency of equipment has shown that the payback period, depending on the type of project, ranges from six months to six years, and this is a very good indicator when compared with investments in traditional enterprises. And this is completely natural, since with a constant increase in energy prices, thanks to the high energy efficiency of equipment, the period of financial return becomes shorter.
According to expert calculations, it turns out that increasing the energy efficiency of equipment in Russia by just 1% will ensure a significant increase in GDP. This can be explained, among other things, by the fact that the required costs for measures to improve the energy efficiency of equipment in the fuel and energy sector, industry and utilities are two times lower compared to capital investments in the construction of new facilities with traditional technologies. And if we take into account the amount of resources in the form of oil, coal and gas that will be required for an equivalent increase, the conclusion suggests itself: increased energy efficiency of equipment is the additional power needed by our growing economy. Power that will allow, while maintaining production volumes, due to rational use and savings to transfer the “extra” energy to another consumer.
Increasing the energy efficiency of equipment is not advertising slogans or dubious demands of environmentalists, but a commercial means that allows you to increase profitability and strengthen your financial position. In general, increasing the energy efficiency of enterprise equipment leads to:
reducing energy costs;
increasing the profitability of enterprises;
increasing the quality of manufactured products;
formation of a positive image of the company;
increasing the competitiveness and capitalization of the company.
For every enterprise, settlement, and even for each building in the future, a program should be developed to increase the energy efficiency of equipment. And its step-by-step implementation will lead to rapid economic growth in our country, increased labor productivity and improved environmental conditions.
