In this article, we aim to showcase our latest case studies to illustrate our expertise and approach in developing renovation plans for high-rise buildings.

In the late sixties and early seventies, modern high-rise apartment buildings sprung up at a rapid pace on the outskirts of central cities in Flanders. In just a few years, they transformed the skyline of Flemish centers. These post-war buildings face several preservation challenges that bring their societal importance back into the spotlight. Many of these buildings were not designed for long-term durability and were built with materials and techniques that have proven to be less sustainable over time.

Now reaching their 50th anniversary, the signs of ageing are becoming increasingly evident in many of these buildings. Many of them require thorough renovation, which poses a significant financial challenge for the owners. Conducting a thorough renovation requires expertise to know where to start, which measures to take, and in which order. Owners who wish to make their property more sustainable can find it overwhelming to navigate through the process.

Residence West side, Knokke-Heist

To address this, we offer master plan studies that provide a clear and detailed plan for improving the spatial quality and energy efficiency of the building, with an emphasis on creating safer, healthier, and more comfortable living spaces. Additionally, we request the integration of renovation work into the overall lifecycle of the building.

We have extensive experience in developing renovation plans, gained through numerous projects along the seaside where harsh weather conditions pose a challenge to building components. Our expertise spans across Belgium, working with various clients, settings, and communes. In response to the growing demand for high-rise apartment buildings, we have honed our skills in tackling the complexity of such structures, which entail stricter regulations on installation and fire safety.

Our approach transcends mere compliance with standard regulations. We strive to incorporate necessary elements into the building design. Our ultimate goal is to empower property owners in their pursuit of sustainable properties, while delivering optimal living spaces.

Case study - Kruishof III

The project involves the redevelopment of a residential tower with 148 units located in Antwerp. together with our branch de baes architects, Sweco and FPC, we combine our expertises to draw a renovation masterplan for the building. The primary objective is to comprehensively diagnose the building's condition and use its defects as leverage to propose sustainable and innovative renovation scenarios.

The project involves creating a Masterplan Study that outlines spatial and energy efficiency improvements, focusing on creating safer, healthier, and more comfortable living spaces while integrating renovation work into the building's lifecycle.

The plan involved identifying necessary repairs, replacements, and upgrades over a 20-year period and creating a maintenance plan that separates necessary investments from planned energy renovations.

Initial Building Inspection

When we inspect a building, our process begins with a comprehensive evaluation of its safety features, fire safety measures, and accessibility. We delve into the structure and components to ensure they meet safety standards and regulations, while also identifying any long-term risks.

We create a detailed report covering the technical, installation, safety, and livability aspects of the building. Additionally, we pinpoint which components need replacement or upgrades in the next two decades. We also conduct a defect inventory, assigning condition scores and priorities to each building component. These scores give us a complete picture of the building's condition, guiding our strategic renovation plan.

Using this information, we develop a 20-year plan, known as the Multi-Year Maintenance Plan (MJOP). This plan optimizes costs by distinguishing necessary investments from planned energy-efficient upgrades.

Furthermore, we introduce a sustainable renovation concept called the Renovation E60 scenario, which not only enhances energy efficiency but also elevates the overall energy performance, quality of life, and comfort of the building. This approach adheres to the trias energetica concept:

1. Reducing Energy Demand: We focus on proper insulation of the building shell.

2. Using Renewable Energy: We replace existing installations with more efficient ones.

3. Efficient Energy Use: This includes low-temperature heating, limiting pipe lengths, insulating pipelines, enhancing ventilation systems, and utilizing heat pumps.

We run EPB label calculations to determine the best combination of installations and equipment. We blend technical expertise with design considerations to assess their impact on the building.

Utilizing BIM technology, we swiftly calculate various design options and analyze their financial implications. This empowers building owners to compare straightforward solutions with those that offer significant added value for a modest extra investment. In parallel, we develop a sustainable renovation plan aimed at bolstering energy performance, living quality, and building comfort.

The building is adapted to sun exposure, designing shading solutions tailored to the building's orientation, making the living spaces more comfortable and reducing the need to use mechanical cooling devices.

Enhancing fire safety requires integrating new fire escapes. Rather than just addressing this need, we seek ways to enhance comfort and quality of life. We extend emergency exits, also serving as expanded balconies for all apartments.

Modernizing post-war buildings as a foundation for the architecture of tomorrow involves distinct challenges. To tackle this, we explore creative solutions that embrace the building's historical context while enhancing its aesthetics and functionality.

Throughout this process, we constantly test the financial feasibility of our measures. Drawing on a database of concrete prices from recent renovation projects, we estimate costs for various scenarios. We meticulously plan the renovation work, considering possible phases and assigning priorities based on the building's condition. Our study also includes budgeting for ongoing maintenance, ensuring the project's long-term sustainability.

By conducting this feasibility study, we provide a clear financial picture, empowering our client to make well-informed decisions.
