Steven opts for a radical energetic renovation

In 2017 our architects An and Piet visited Steven from Mol. He contacted Kamp C with the question how he could best tackle the renovation of his house from 1933 in order to reach a low E-level. Three years later, works have already been carried out, but numerous renovation works are still planned. We went to have a look.

Why did you contact Kamp C?

Steven: "We bought our townhouse in 2016. But the house was barely insulated. So a thorough renovation was urgently needed. I immediately contacted Kamp C, because they have experts in house who can help me to make informed decisions when renovating my house (approach, choice of materials...).

What were your questions?

Steven: "These were my questions:

1.           Is there a risk of moisture problems if we choose indoor insulation?

2.           Is it best to opt for double or triple glazing?

3.           Is it best to opt for a demand-driven system C or D?

4.           What is the best construction and choice of material for a new floor to be insulated?

5.           How do I handle the installation of a cistern?

6.           What is the best choice for gypsum fibreboard and plasterboard?

7.           What are the options to maximise natural light in our townhouse?"

What things did you want to renovate at the start? And which things have you renovated so far?

Steven: "In 2017, a parking roof was installed and we insulated the ceiling above the servitudinal passage with hemp. At the start, I wanted an IER (Intensive Energetic Renovation) renovation that would lower our house below E-level 60, this level indicates the energy efficiency of the building. Apart from the energy efficiency, we also want to upgrade our first and second floors (new stairs, new plaster...).

In the meantime, the EPB preliminary study has taught me that E-level 60 is not feasible, because we want to leave our facade as it is now, so now we are aiming for an E-level below E90. But actually, our planned renovation interventions, in terms of energy, are the same as those at the start of our project. We did have to drop the upgrade of our first and second floor because of too high costs. So all the works still have to be carried out".

Which things are you going to renovate in April during your major energy renovation?

Steven: "The renovation of the rear building, floor insulation, carpentry (triple glazing), a new condensing boiler, a demand-driven system C, insulation of the back facade and facade at the service-institution (interior wall insulation), the installation of solar panels and the renewal of the electricity.

Thirty-two percent of the CO2 emissions in the Kempen region come from households. Aging homes, poor insulation and inefficient techniques contribute to this figure. In order to tackle the outdated housing stock, IOK started the SHINE neighbourhood renovation project in 2016 in collaboration with Zonnige Kempen, Kamp C and Thomas More's Energy Knowledge Centre. SHINE stands for Sustainable Houses in Inclusive Neighbourhoods. As part of the project, the architects of Kamp C visited more than one hundred homes in Kamp C with renovation advice.
