Energy renovation: replace the boiler or start by insulating the house?

Not everyone knows that the effect of energy renovation depends on the order in which the work is carried out. It is worth paying attention to this, especially when applying for financing.

Retrofitting a home is a major undertaking for which we are happy to obtain co-financing through schemes. However, not everyone knows that replacing the boiler is not enough to improve comfort and reduce bills. In addition, it is very important to carry out the work in the right order.

Energy retrofit - why does it have to be comprehensive?

Uninsulated or inadequately insulated houses generate high heating costs because most of the heat simply escapes. The situation is even worse if the building is heated by an old, inefficient and polluting solid fuel boiler.

The solution to the problem is thermal modernisation, for which it is now possible to obtain a grant. Public subsidies include a subsidy for wall and ceiling insulation, a subsidy for boiler replacement and a subsidy for the purchase and installation of mechanical ventilation with heat recovery. There are also regional programs, for example, to fund the replacement of "fossil fuel" heaters in a given municipality.

However, many people make the mistake of only replacing the boiler or insulating the house. Such timid measures cannot have the desired effect. A new boiler in an uninsulated house means that most of the heat will still escape to the outside. On the other hand, insulating a building without replacing the boiler will make the house more pleasant to live in, but the boiler will still consume huge amounts of fuel and pollute the air. A comprehensive approach is therefore necessary.

Energy saving renovations - Grants and subsidies

When starting an energy retrofit project, it will be best to choose materials that are better for the earth. This can help reduce the strain on the earth's natural resources and the environment. Energy efficient building materials are more affordable and offer a better solution for improving the energy efficiency of your buildings. In the following paragraphs, you will read about some of the benefits of choosing more environmentally friendly materials.

With regard to energy costs, the overall cost of building renovations is significantly affected by the materials used.

Materials such as wood can be very expensive when they need to be replaced due to their high energy costs. This results in increased construction costs and decreased property values in these areas. The use of materials that will be friendly to the environment can provide better solutions and reduce the negative effects of this construction work.

 

The use of good insulating materials is able to improve the energy consumption of your building without affecting the structural integrity of the structures.

There are many instances in which the costs of a renovation are determined by the amount of insulation material that must be used. By selecting insulation materials that are good at insulating heat and cold air, the total cost of your project can be reduced and improved. A serial renovation project that uses good quality insulation can have a lower cost-benefit ratio than a building that uses poor quality insulation materials.

 

Other types of renewable insulation sources can be used in the energy retrofit process. These include the use of cellulose fibre boards as roofing materials or the installation of thin-film insulation materials under the walls of your home. If the renovation will be undertaken in a cold climate, straw, hay, cardboard or paper insulation materials are preferred. For a warm climate, ceramic tiles can also be used to insulate your buildings and they can also be an environmentally friendly choice.

 

You can take several measures to reduce power consumption while completing an energy renovation project. These measures in the form of energy bonuses or financial aid include the implementation of energy-saving renovation techniques. You can incorporate these techniques in the design phase and during the construction phase as well. In addition, you can also have insulation applied to the walls of your buildings for which financial aid is available. These techniques will all contribute to reducing the total power consumption while completing an energy efficient renovation.

 

  • The second phase of an energy retrofit procedure involves the provision of low-cost renovations. This includes the provision of new windows and roofs. Many of the tenants in your building may not be able to provide new windows and roofs for their homes. If you take advantage of the grants and financial assistance available from governments, you can therefore provide them with substantial discounts when it comes to the purchase of such replacement items. This will ensure that your tenant enjoys a comfortable living environment while reducing your own expenses on the energy efficiency of your premises. On top of that, some tenants are unable to pay for the cost of their renovated unit.

 

  • The third phase of the process involves retrofitting your buildings. This means that you will have to implement energy saving techniques in your renovation plans. This is one of the most important aspects of the renovation process. If you want to complete an energy efficient renovation, you need to include a variety of different methods in your plan. For example, instead of using a fan in the air conditioning, you need to invest in a water distribution system so that you can cool your rooms efficiently without using your air conditioner.

By using such innovative energy saving methods, you can significantly reduce your electricity consumption while improving the quality of the air circulating in your residential buildings.

 

You should also consider what measures you can implement immediately after the completion of your renovation project. For example, if you cannot carry out any type of insulation or other building modifications, you should at least try to use the available insulation materials designed for renovation purposes. In addition to this, you should always make sure that you carry out renovation procedures in a planned and systematic manner. By doing so, you will be able to save on the costs that you would have incurred if you did not start the renovation project in a planned manner.
