Implementation of Energy Efficiency Measures for 13 New Facilities in FBiH
New investments in energy efficiency worth 4.3 million BAM
Following the renewal of 18 public buildings in the Federation of Bosnia and Herzegovina last year, within the framework of the World Bank BEEP project (Bosnia Energy Efficiency Project), the implementation of energy efficiency measures continues this year.
By signing contracts with contractors, new investments have been planned for 13 public buildings, in Zenica-Doboj Canton (five facilities), Canton 10 (two facilities), Canton Sarajevo (one building) and facilities of importance for the Federation of Bosnia and Herzegovina (five facilities).
The total investment will cover 6 educational institutions, 2 health institutions, and 5 other public buildings, as stated by the Federal Minister of Physical Planning Josip Martić upon signing the contract. He added: “I am happy to see that energy efficiency is becoming an increasingly important topic. I can proudly point out that we are very pleased with last year’s results and that its positive effects have transferred into this year. The multiple benefits of such development projects have already been widely recognized and we are delighted when through their implementation, we can improve the conditions in public buildings but also achieve significant savings in energy costs and CO2 emissions.”
Implementation of energy efficiency measures for the renovation of public buildings is part of the largest energy efficiency project in Bosnia and Herzegovina – BEEP (Bosnia Energy Efficiency Project), which, in the period from 2015 to 2018, is investing 32 million USD, 19.23 million USD of which was allocated to the Federation of Bosnia and Herzegovina.
The project is implemented in public facilities in the fields of education and health through the implementation of measures such as window replacements, installation of thermo facades, improvement of heating systems and others.
Spring Home Renovation
Save your money by implementing energy efficient measures.
Save your money by implementing energy efficient measures
Spring is an ideal time for performing work on your home that will provide you with a pleasant stay in a relaxing and warm space, without fear of extreme coldness in the coming winter season. Also, if you are renovating your apartment or house, you can forget about the unbearable heat in the rooms during the warm summer months. But how can you make your home comfortable for any season of the year? The answer is very simple – implement energy efficient measures.
You can already start renovating your home as it can help you to improve it and make it more energy efficient. You invest in a more inexpensive and safer future with this process. Regardless of whether it is a larger project such as installing solar panels on your house for heating hot water, or a smaller project like replacing your apartment windows, your budget can be saved from further wasteful spending. With the help of experts from the largest energy efficiency project in B&H, BEEP (Bosnia Energy Efficiency Project), we have investigated which methods in the construction industry can be applied to make your home energy efficient and ultimately save you money.
1. New or additional insulation of your roof or attic
To begin with, experts in the field of energy efficiency recommend to set up good insulation of the place in which you live. Quality insulation of the roof or walls can help reduce the amount of heat that enters your home when it’s hot, or keep the heat inside when it’s cold outside. There are many roof isolation options that depend on the preferences and options you have. The most popular options are stone or glass wool, reflective film, or clay slate that absorbs moisture well and is resistant to frost.
2. Renovation, thermal insulation of facade
If you have decided to renovate the facade, use materials such as expanded polystyrene (EPS), or Styrofoam. Styrofoam is still used in construction as a suitable choice for wall insulation, because it is lightweight, possesses good mechanical characteristics and it is easy to install. It also has extremely low moisture absorption rates and above all, it is a great thermal insulation. However, there are other, newer, materials that could be placed on the facade that achieve higher thermal power. Inform yourself about graphite Styrofoam, a gray facade Styrofoam that contains graphite polystyrene. It is thinner compared to ordinary Styrofoam, and the graphite component in its composition results in about 20% better insulating properties to the object it is placed on. You can also cover the facade with mineral wool. By placing a mineral wool, with a fireproof facade, you get better heat and sound insulation.
3. Replacing windows and doors
In addition to the roof and walls, your windows and doors are the main source of heat loss from your home. Replace the window frames as they easily result in heat loss. The best window frames are aluminum, as well as a combination of aluminum-wood (wood on the inside of the window). Look for a window system with multiple chambers. The best systems are windows of 5 or more chambers – multilayered windows with a higher number of windows that are arranged so that their interspace is filled with noble gas. Low-e windows are the highest quality windows. Their interspace coated metal film passes sunlight, while retaining heat in the interior at the same time.
4. Use sustainable building materials
If your aim is building an energy efficient home, use materials that are environmentally acceptable. Every part of your house or apartment from the floor to the roof can be built from sustainable building materials. Use products such as old wood, recycled glass and plastic or natural materials such as bamboo, cork or linoleum. You can also reuse your wooden floors or doors, but they need to be restored.
5. Change the house lighting
In addition to heating or heat energy, most of the time, many of us use electricity in waste in our homes. With proper planning of lighting, you can replace all light bulbs with energy saving or LED light bulbs. Perhaps they initially cost more, but the long-term result is greater money savings and a longer lifespan. These light bulbs last 8 to 12 times longer than ordinary light bulbs, according to energy efficiency experts. Almost all energy that energy saving and LED light bulbs consume is directed towards producing light, in contrast to ordinary light bulbs with an incandescent bulb that convert a great deal of energy into heat. Also noteworthy is that energy saving and LED light bulbs do not contain a high concentration of toxic elements, such as mercury.
6. Install the ceiling fans
Instead of an air conditioning split system that consumes a lot of electricity, you can install ceiling fans in your living room and bedrooms. Fans are cheaper and do not consume as much electricity as air conditioning systems. They are also healthier because they do not accumulate harmful bacteria, which is the case with the air conditioning split systems, so your respiratory system is not compromised. The fans properly distribute the air in the room, so it is easier to maintain the optimum room temperature.
7. Replace / install programming thermostats
According to the information provided by the representatives of the BEEP project, more than 50% of the energy in our homes is used for the heating and cooling of the rooms we are staying in. The simplest way to reduce the cost of heat is to install a programming thermostat with the heating system. When it reaches the set home temperature, the temperature control system will start working. When using a thermostat, if for example you set it up one degree lower in the winter or one step higher in the summer, you will save as much as 3-5% of energy and therefore, money as well.
If you are already thinking about renovating your house or apartment, consider making a wise investment – allocate your budget to get your money back in several years. It is very important to hire a quality contractor, or consult with experts (engineers) who will help you choose modern, fully usable materials. Their use will contribute in achieving the goal of renovating your home in an energy efficient way. Implementing certain energy efficient measures is an investment you make once in your lifetime. Even if you only implement two or three measures while renovating, you will notice that not only are you saving energy and money, but the environment as well.
How to Choose the Most Efficient Home Heating Energy Source?
Winters in B&H tend to be mild, but also very cruel. Numerous families are receiving bills that are a reminder of how high energy prices are compared to the standard of living in B&H. The goal of each household is to use the best, but also most financially favorable energy source. So, we made a brief overview of the cheapest and most efficient energy sources for heating households.
One of the most inexpensive energy sources is wood; the price of a spatial wood meter without transport is 60 to 90 BAM. Heating in this way is a pretty demanding job though because the wood must always be carried into the house, inserted into the stove, and the fire maintained so it does no go out. According to B&H environmental associations, when using wood to heat, energy efficiency mainly depends on the water content. The fuel value of wood falls if it has a percentage of moisture higher than 25%. It thereby matters which wood you choose, and how you store it before and during the winter months. The great advantage of wood is that it belongs to renewable energy sources, and its combustion of CO2 emitted into the atmosphere is considered neutral.
Lately, an increasingly popular way of heating in our country is with pellets, which are considered a renewable energy source. Pellets do not contain sulfur, chlorine, heavy metals and other compounds harmful to one’s health. Pellets are made from pressed wood and sawdust under high pressure. Pellet handling is clean. One simply places the pellet in the oven and occasionally throws out the waste. The price of pellets is around 300 BAM per ton. The pellet stoves are the largest investment with prices of 1,000 BAM and up, depending on the capacity.
In addition to wood and pellet heating, one of the cheaper ways to heat is with gas. Households that are heated by natural gas are mainly residential buildings that have the ability to connect to gas and install floor heating, the price of which depends on the size of the space. The possibility of regulating the temperature automatically and boiler operation is another advantage of heating gas. On the other hand, monthly bills for heating depend on the size of the rooms you live in, but also how energy efficient the building is, that is the quality of the built joinery and thermal insulation. The price of gas on average is 0.60 BAM per Sm3. Natural gas is environmentally friendly and energy efficient because it hardly contains sulfur compounds and in its combustion releases a small amount of CO2.
When we ask about cost-effective and efficient heating, electricity is imposed as one of the possible answers. According to the Agency for Promotion of Foreign Investments in B&H, the average price of electricity is 0.20 BAM per kilowatt hour (kWh), in a higher tariff, while the average price of electricity at a lower tariff is 0.10 BAM/kWh. The most popular heating by electricity systems are convector radiators, because they are lightweight, nicely designed and easy to set up. These radiators cost 200 BAM and up, though used ones can be purchased for less. Built-in thermostats do not allow for the heater to cool down, so if the apartment is small in size and with heat insulation, heating on convector radiators can be a good but not a long-term option.
We can also add the use of coal kiln to these forms of heating of facilities. The price of coal is extremely favorable, with one ton costing 120 to 160 BAM depending on the quality; while the price of a stove is 500 BAM and upwards. On the other hand, the combustion of coal emits a large amounts of sulfur dioxide and heavy metals, which leave long-lasting consequences to human health, but also to polluting the environment through greenhouse gas emissions.
If you consider all of the noted prices and characteristics of heating, you must not forget that there may be cracks or holes in your home, which cause great energy losses. Thus, the biggest obstacle to energy-efficient heating is the absence of heat insulation. Installation of facades with heat insulation on the house, as well as the installation of quality windows requires a certain financial cost, but it is worth it in the long run. In fact, in a few years you will get a return on your investment, because it will reduce energy consumption between 40 and 60 percent.
In the selection and use of energy for heating, you should also bear in mind that the energy source you use affects the environment, because many people are not aware of the air pollution caused by burning coal or other traditional methods of heating interiors.
