Building refurbishment

About our articles in the “Blog” tab

Tibor Rigo Blog , , , , 0 Comment

First of all I would like to thank you for all the positive comments, feedbacks on our articles.

Let me reply to that most common question that we receive.

“Who writes our articles and how is it that the discussed topic (though being quite professional) is so easy to read?”

  • Eco news articlesOur “blog” was / is / will be intended to be a “News” tab that communicates useful information to our customers.
  • The articles are not written by a freelance copywriter.
  • They are written by the diagnostic engineer of our company (who also happens to be the director of the company) using his own experiences, expertise.
  • We aim to use “layman terms” where possible, the articles are intended to give customers, non-professionals relevant information about economical building solutions.
  • Prior to publishing the articles are revised by a non-professional (just to make sure every bit of information “reaches” our readers the right way).
  • The main idea is to help the decision making process of our customers; we aim to provide enough information so the topic is readable, understandable yet not too “dry”
  • Also we noticed that by having these information our customers have a better understanding of the refurbishment / extension project ahead of them.
  • These articles will provide a picture about us as well, about our ideas and expertise.
  • Often we will aim to destroy some of the “ancient”, false ideas of building (e.g. mould treatment) – we believe in the success of our method.

We would still like to hear from you, so do keep sharing your thoughts, remarks, critiques even.

And ask for our on-site diagnostics that is still free in March.

How to improve your home’s EPC rating

In the previous part we talked about what important pieces of information we can learn from a property’s EPC certificate. If you have read all 3 previous parts of this article series, by now you are aware that a building’s EPC rating does not necessarily depend on the age of the building or when it was last refurbished.

Epc- planingHow can you turn your house into a healthy, economical, energy efficient home, or how can you make nearly double the profit when selling your property?

As we said in the previous part, a property’s market value can be increased by approx. 15-20% by refurbishing it (regardless of its EPC improvement). Taken into account the invested amount (the cost of the refurbishment) one will realise a profit of 6-8%; in some cases this may be as high as 10%.

Below you can see some of the added benefits of economical refurbishment:

  • Healthy building, (mould-free environment – can mean 10 extra years)
  • Economical operation of the building, you can save up to 50% on utility bills
  • Better EPC rating means another 8-15% increase in the market value – this can almost be converted into profit completely (total profit after economical refurbishment: 16-18%)
  • Reduced carbon footprint (less energy required) – environmentally friendly building
  • Increased comfort level
  • The property will be on higher demand, will sell quicker, easier
  • A well-planned scheduled refurbishment means saving time and money – a highly profitable investment that creates additional value

The increase in the EPC rating can be predicted when the refurbishment process is planned thoroughly, consciously.

epc - main steps of refurbishmentThe main steps are:

  • On-site inspection, diagnostics
  • Energetic calculations, project preparation, implementation schedule
  • Strict supervision in implementation, daily documented progress
  • Quality checked materials and technologies
  • Attention to deadlines
  • Accountability upon and after completion – even for the structure
  • Ordering new EPC certificate from independent firm
  • Repeated survey (if required), even for control purposes

As always, do not hesitate to contact us if you have any questions or just feel like sharing your thoughts.

EPC rating in relation to comfort level

First of all, let me thank you for showing your interest in this rather dry but absolutely vital topic. EPC rating cannot be ignored during today’s energy prices and pollution.

  • Is your house due for a renovation? Would you like to make it cosier?
  • Would you like to sell your house quicker with bigger profit?
  • Or you have just purchased one, and you would like to redecorate it prior to moving in?

If you are in any of the above three groups, you should definitely keep reading.

High EPC rating property on the market

Everybody knows that renovating a house will increase its value (if done properly). Depending on its location and the quality of the material used during the refurbishment project, a property’s market value can go up by an average 15-20%. We can safely say that two adjacent, similar-sized houses (one of which has just been refurbished) will sell with a minimum difference of 15% in price. If the renovation included a heating system upgrade as well, your EPC rating may go up by a few points, but the house is likely to remain at the same EPC level. It is because this change has not been done purposefully to improve the EPC rating, it just so happened to improve it. The amount invested in the refurbishment will not bring the desired improvement in EPC rating. For example EPC 68, the score mentioned in our previous article, can be increased by 5-6 points only by having an upgraded heating system. With that, we can achieve Level C rating in EPC, but other main features of the building have not been changed, so the building is still uneconomical. The only difference is, now it is uneconomical with a modern heating system installed.

A modern, economical heating system should be the solution to all these problems, wouldn’t you say? After turning on the heating, the house should get warm quicker, and the fact that the unheated areas of the house (lounge, hall, kitchen, etc.) get cold during the night should not bother us at all. Isn’t that right?

mould

  • What one probably does not realise while staying inside the house: a significant part of the heating energy escapes through the poorly insulated walls, floors (remember, we are talking about a house with level C or D EPC rating) – this is very uneconomical.
  • No matter how efficient your heating system is, because of the high humidity and the damp cold walls, mould will appear in the corners. Your home is a little more modern now, but it is still an unhealthy environment.
  • Most of our customers wanted us to look into the following issues: draught (around the windows even “through” the walls, but most commonly through the floors) they can feel the chilly effects of the cold wind inside their houses. This happens because of the ventilated flooring. This system is still used today, although it is a faulty concept.

A modern heating system on its own is not able to tackle the above mentioned issues. Now you have a nicely refurbished home, with a fairly modern heating system that still does not provide the comfort level you are after.

Unfortunately these factors that ruin the comfort level are present in the new properties as well. It is very hard to face the fact, for new property owners that even though they have just purchased a new home, they will still need to invest more money into it in order to turn it into a cosy home.

thermal image

Before you purchase a new house or flat make sure to check its EPC diagram. It will tell you everything you need to know about the building (energy efficiency-wise). If the rating is below 75, you can be almost certain that you shall live with mould. And no, painting will not solve the problem. The problem originates from the structure of the house. Even if your EPC score is between 75-85 you are likely to have mould in your house. Poor ventilation, cold surfaces and the ever present humidity, together can result in mould occurrence.

It can be very upsetting when in order to resolve all of  these issues, one needs to spend an extra 8-10% of the price of a recently purchased property.

Ask for our expert advice, calculate and you will see, it will be worth investing money in order to save money. When it came to valuable properties, it used to be location, location, location. Now, it is more like EPC, EPC, EPC.

It is still not the end, in our next article we will talk about why it is important to carry out diagnostics prior to purchasing a property and how to solve all these issues related to poor EPC rating.

EPC rating
EPC rating diagram sample

In the first part of the article we tried to provide a general overview about Energy Performance Certificate (EPC). Today we are going to explain what different ratings mean, and how they affect our everyday life.

To demonstrate these effects, we chose a home with the most common EPC rating on the British market. The diagram below belongs to such a house.

diagram about-uk-domestic-EPC-rating

The EPC rating is 68 (level D). Most homes in the UK have a rating between 55 and 75, so we can say this example represents an average UK home. Now is this value good or not? I know I said this was an average value, so I might shock a few readers now when I say this value is very low. To tell you the truth only 2% of the British homes have a level B or higher rating.

Having today’s technologies and materials at our disposal it seems to me that this value is just not good enough. Although the climate varies on a large scale throughout Europe (think about the Mediterranean, Greece, Spain, Portugal and the northern countries such as Norway or Sweden) they manage to have a better overall rating in domestic EPC rating than the UK, regardless of their climate. This is because of the physical features of the buildings, the materials and technologies used, therefore the operations of the buildings are much more economical there (average EPC rating in Europe 75-80, in Germany this value is 85). Sadly the UK is significantly behind these countries in terms of domestic energy consumption.

The importance of thermal insulation started to become a factor in Europe since the ‘70s, whereas in the UK, energy efficient building technologies have only just started to be of high demand.

This results in quite significant arrears. We can still catch up to the leading European countries (in terms of high EPC rating domestic buildings), but we have to consciously design the new buildings and also plan the refurbishment projects.

The meaning of EPC rating 68:eco EPC rating A

  • cold, draughty floor
  • damp house
  • mould occurrence in corners, around windows, behind cupboards or in the bathroom – unhealthy environment
  • the changes in the outer temperature is perceptible inside the house even next to constant heating
  • high energy bills, high pollution emission

These conditions can easily be improved by professional diagnostics and the usage of modern building materials. Upgrading the windows to double-glazed or triple-glazed will not be sufficient on its own (it is a start nonetheless). To upgrade your house’s EPC rating to level “B” is easily achievable if you plan your next refurbishment project thoroughly and energy consciously – and it does not have to cost more!

How is this possible? What are the costs and how quickly will such an investment show financial return? We will elaborate these in our next article.

As usual, please feel free to share your comments, own experiences or relevant stories you may have.

What does EPC mean?

EPC rating 1

In this article we will try to help you understand what EPC means furthermore what it means in regards to your property. It is the mandatory document that goes with every property sale; EPC stands for Energy Performance Certificate.

It basically shows you how economical a building is. But what does it tell you exactly?

It is a classification that is based on a pre-determined scale (A – G, “A” being the most economical category). The categories are determined by direct measurable factors and indirect calculations.

The two most important factors are:

  • The measure of energy required to maintain a certain temperature inside the building
  • The thermal storage capacity of the building (calculated from its physical features)

These two factors are absolutely independent from one another. We can maintain 20°C in a room by either

  • Little usage of the heating system, but in a building with excellent thermal storage capacity
  • Or with massive energy consumption (constant heating) in a poorly insulated building

EPC illustration

In both cases we would be sitting in a 20°C – room; so the result would be the same, yet what a difference in the energy consumption.

But the biggest difference is this: Let’s assume we turn down the heating in the living room for the night. In the first case (well-insulated room, excellent thermal storage capacity, high EPC ranking), not only, will the air  remain a pleasant 20°C in the morning, but also all the solid objects (floor, walls,  furniture, etc.) will not get cold. Whereas in the second case (poor insulation, poor thermal storage capacity, poor EPC ranking), we will definitely need a sweater till we have our first tea in the morning.

We are yet to highlight all the financial benefits that you can enjoy by having an economical home, with high EPC ranking. You can read about the costs of such an investment and the break-even time in our next article. Also we will explain the meaning of the different categories, e.g. what it means to have a home that is classed “D” in its Energy Performance Certificate.

In the meantime browse through our website for more interesting articles about insulation and heating technology, or contact us with any questions you may have.

Overview of EcoPropi’s various technologies

Introduction, brief description:
  • Do you have mould/mildew in your home? Did you try to get rid of it, but it just keeps coming back shortly after the treatment?
  • Are your walls and floor constantly cold, making your home cold as well, even though the heating is on?
  • Do wet staines appear on your walls? Plaster falling?
  • Would you like to eliminate the hazards mentioned above, and at the same time, save on your energy bills, and improve your property’s value?

We offer complete planning and energy surveying buildings, assembling and upgrading insulation systems. We eliminate moisture penetration, thermal bridges and mould with the use of injection, spray foam insulation, etc.

We will increase the efficiency of  the thermal insulation and build renewable energy systems as well, and as a result we will be able to reduce your energy bills and improve the comfort levelof your home.

injection, insulation, pumps, etc logos
brick wall injection, insulation
Efficient technologies customized to clients’ needs:

 

  • Initial assessment of customer needs, full inspection of the property (heating and ventilation systems, structure, doors, windows, etc.) energy survey. Calculating energy consumption after renovation and preparing quotation for reconstruction.
  • Removing existing mould by treating the affected areas.
  • In the absence of waterproofed walls we carry out emulsion – injection in order to prevent water and soil vapor penetrating the structure.
  • Applying closed-cell foams on walls, joists and even on the existing thermal insulation and waterproofing the roof.
  • In some cases the conventional techniques can also be used effectively: bitumen felt, polystyrene board insulation.
  • Upgrading  heating systems by installing condensing boilers, heat recovery ventilation, heat pumps and internal surface heating.

 

Our activities in details:
Needs assessment, energy survey, quotation:

Your living conditions and the value of your property could significantly be improved by investing in renewable energy. Whether you are selling your property, have just purchased one, or it is time to renovate it, it is worth considering a long-term profitable investment. Increasing the value in a way that you could feel every day. Getting rid of mould and the uncomfortable feeling of cold walls, unwarmed, draughty rooms and bad atmosphere… own a pleasant home!

In case of advanced insulation we provide energy survey if requested, hence changes become evident. You will be able to see the difference in the energy classification of your property, the value increases and your heating costs will decrease.
We provide a written quotation both for minor and complex insulation works.We use thermal imaging before and after renovation.If you are not satisfied with the appearance of your property (i.e: obsolete bricks, plaster) full facade insulation is recommended before renovation. We execute thermal insulation with state of the art foaming systems and reconstruct your property by faux brick wall panels.
Injection:

We eliminate moisture problems which are highly responsible for mould growth. The film, emulsion formed after injection prevents the moisture absorption into the brick walls.

cavity wall spray foam insulation
 

The role of modern doors and windows:

If the walls are already well insulated and the heating system warms up the house, we should not let the heat escape through doors and windows. Often the weakest link is the window. They have an important role in building energetics.

Anti-mould paintings/coatings:

In many cases we see mould retardant paints, primers that promise us they eridicate mould forever. However, these are only temporary solutions. As a first step we eliminate the conditions of mould growth such as moisture, humidity, cold surfaces where moisture condenses and initiates mould growth. With our previously listed equipments we eliminate moisture penetration, cold surfaces and ventilate vapour. We use surface treatment (e.g: mould remover, special paint in order to kill the remaining mould) only after these actions, as the substances used to treat the surfaces will not achieve the same long-lasting result as injection and spray foam insulation.
