Raising The Roof: First Ever Blue Green Roof in Dublin Constructed with ACO’s RoofBloxx System

With new planning rules to abide by in Dublin, the developers of a commercial three-story residential apartment building had to demonstrate that its scheme would have a blue green roof to obtain planning permission. ACO worked together with Beton Construction Services to design and specify an innovative blue green system that would manage stormwater runoff, improve resilience, and be the first of its kind in the city.

 

Creating a waterproof roof

A key part of the consultation was ACO’s assessment of the hydraulic requirements, which was based on 1 in 100-year time series rainfall, as well as accounting for a 40% uplift in climate change. Following the assessment, ACO specified its RoofBloxx attenuation system to cover a catchment area of 131.8m2, installed on an inverted blue roof.

Introducing the ACO solution to an inverted roof separated the competing drainage requirements. By engineering an elevated shallow structural attenuation system that operates independently of the flat roof drainage system, it allowed the roof to be engineered to known standards and best practice, without compromising the ability of the roof to drain quickly in extreme circumstances.

Dan O’Connor, Business Development Manager at Beton, led the project and said: “When we were approached about this job, we knew we’d need guidance from blue roof specialists. We turned to ACO because we know they not only have innovative products like the RoofBloxx system, but they have the knowledge, experience and assisting tools to make sure that the job runs smoothly. With ACO’s support, the project was swiftly granted planning approval, and we and the developers have peace of mind that the roof is protected for years to come.”

Designing climate resilient Blue Roof attenuation systems.

Given the unprecedented extremes in climate change that the UK has experienced in the last few years, local and national planning policies have developed to ensure that developers, architects and engineers fully consider the impact that a changing climate will have on the performance of buildings.

For example, the recently revised London plan requires developers to incorporate ‘urban greening’ on new developments, and to consider rainwater water reuse as the priority in managing surface water runoff. This has seen a substantial increase in specification of blue roof attenuation systems, which are seen as an ideal method for managing both extremes of climate change in conjunction with green roofs, as they control run off and can help mitigate the effects of summer storms and the flash flooding, they can cause. Blue roofs also provide the added benefit of enabling water to be reused either as a passive irrigation system or as a more conventional rainwater harvesting system.

However, the design of blue roof attenuation systems is not governed by any specific standards, and it is important to understand the differences in function of a flat roof system and that of a blue roof attenuation system. The design of flat roof systems is governed by a well-established range of British and European standards, as well as Building Regulations. These standards promote the fast and efficient removal of rainwater from the roof surface, as the longer the rainwater sits on the roof the greater the risk of water ingress into the building.

A blue roof attenuation system on the other hand is designed to do explicitly the opposite, as the intention, for very valid reasons, is to hold and retain water for specific periods of time to control flooding and to potentially retain water on the roof structure for later reuse.

Virtually all the currently available blue roof systems rely on the roof waterproofing and roof drainage system having dual functionality and start from the premise that you are designing a roofing system, when what you should be designing is an attenuation system that is located on the roof.

If you take the view that you are designing a roofing system then there are a number design issues that need incredibly careful consideration, for example the number, positioning, and sizing of roof outlets, roof fall gradient, type of roof construction, and period that water is retained on the roof. With this approach you are designing two opposing functions for the roof which will require design compromise, noncompliance to known standards and accepted best practice, and will therefore increase overall building design risk.

Given the novelty of ‘blue roof’ systems it should not be a surprise that developers and buildings insurers are uneasy siting such attenuation systems above residential developments or critical infrastructure, but this need not be the case if a more logical design approach is adopted.

Unlike a normal flat roof that is visible and open to the elements a blue roof system is often a covered structure that may have hard or soft landscaping above it making it difficult to see if the system is performing. If the system becomes blocked then water will be retained in a semi-permanent fashion if there is not an early warning system, or a regular maintenance regime in place.

Designing for resilience, not only requires compliance with standards but also demands full consideration for worst case scenarios: What if the system is not maintained and becomes blocked, how do we want the roof drainage system to perform in such an instance? What if climate change is considerably worse than has been predicted such that the system regularly overtops, how do you want the system to perform in this situation? These are foreseeable events that require design solutions.

The ACO Solution

The ACO RoofBloxx patented blue roof attenuation system answers these design challenges and achieves this by ensuring that function and form are not confused by creating a separate open attenuation system that sits and operates independently of the roof waterproofing and drainage system.

By creating a separate system, ACO ensures that the roof can drain slowly during the design rainfall events, and to hold water for reuse, but that in extreme and unforeseen events e.g., the system is blocked, or the design event exceeded during storms, that the roof can drain quickly in compliance with all recognised building standards. Most importantly water is not encouraged to remain in contact with the roof waterproofing any longer that accepted design practise allows.

This gives Peace of Mind to designers, developers, insurers and building owners, as the ACO system increases the resilience of the overall roofing structure and therefore eliminates unnecessary risk. Additionally, by separating design responsibility there is a clear demarcation between engineering and design disciplines.

Resilience, sustainability, and net zero are standard watchwords for a new generation of designers that seek to increase the functionality and design life of buildings. Understanding the function of a system is critically important to designing an appropriate solution. The ACO RoofBloxx system enables building regulations and planning conditions to be met and enables a climate resilient system to be installed that helps alleviate surface water run-off and does not compromise the fabric of the building.

The introduction of the new Building Safety Act in April 2022 was cited by the government as the biggest transformation in how tall structures are designed, constructed and managed, in almost 40 years.

The Act enforces compliance to Building Regulations restricting the use of combustible materials in the external walls and specified attachments for residential blocks of flats, student accommodations, care homes, sheltered housing, hospitals and dormitories in boarding schools, with a storey above 11 metres in height. It also reinforces the personal responsibility of all parties involved in the construction process.

Within those Building Regulations, sits BS EN8579:2020 – A Guide to the design of Balconies and Terraces, which puts further emphasis on the importance of fire safety in the drainage design of balconies and terraces. It scrutinises the use of combustible materials, such as plastics, in their construction and stipulates that components used should:

  • Neither be composed of materials nor provide a medium for spread of fire
  • Not propagate fire downwards by falling brands or flaming/molten droplets or debris
  • Be designed to minimize the risk of becoming detached from the face of the building
  • Minimize the risk of prejudicing the stability of the building from structural fire stress

Alumasc Water Management Solutions is the UK’s leading manufacturer of integrated non-combustible rainwater and drainage systems encompassing the entire building envelope. To address the newly introduced design requirements we have developed a fully-compliant drainage solution specifically suited to the rigours of high-rise building construction.

The system incorporates Harmer Aluminium Roof Outlets featuring new extended spigots connecting directly to a welded spigot on Alumasc’s Aluminium Downpipes. Both products have a well-established track record of use in the high-rise building sector, but these new developments now present an efficient and compliant package which keeps our building industry colleagues up-to-date with ongoing regulatory changes.

The Harmer Aluminium Roof Outlet range is a high-performance rainwater drainage system suitable for all types of flat roof application, including balconies and terraces. The new spigots for connection to our aluminium downpipe systems eliminate any potential incompatibility which may occur when specifying unrelated products, resulting in quick, easy installation and its associated cost-savings. High flow performance and low maintenance provide complete reassurance which is critical to building drainage design.

Alumasc Aluminium Downpipes have a history of specification on many high-rise projects, and are available in a range of popular profiles. The inherent lightweight nature of aluminium makes them perfect for use at height, whilst their material hardness and fixing mechanisms, give excellent rigidity and high impact resistance.

Both Harmer Roof Outlets and Aluminium Downpipes are BBA approved powder coated, making them A2-s1, d0 fire rated, ensuring conformity to the new regulations in most applications.

To complete the AWMS high-rise offer, the Harmer Modulock Pedestal System offers a range of non-combustible, raised pedestals designed to create level flooring in any building application where sloped, stepped or irregular surfaces present a challenge; perfect for balconies and terraces.

They are manufactured from mild steel with a highly durable zinc nickel, corrosion-resistant finish, making them A1 fire rated. The self-levelling head option is ideal for use with both paving slabs and timber, or a fixed head option is available for use with paving only.

This complete package of non-combustible outlets, downpipes and pedestals is 100% recyclable.

roofbloxx-green copyThe newly patented ACO blue roof attenuation system forms an independent tank that can be constructed on any new or existing flat roof where roof waterproofing has been applied. The system can be installed on a warm, inverted, or uninsulated roof using a single ply, cold or hot melt waterproofing system.

ACO have just launched a new series of animation videos to show how the system is built up and how it functions on a number of different roof types. The system provides the following benefits:

  • Reduces overall building risk by providing greater design resilience for all types of flat roof construction
  • Ensures compliance with Flat Roofing and Drainage building standards and The Building Regulations, allowing the system to drain slowly in normal use and quickly in extreme conditions.
  • Ensures compliance with The SuDS Manual hydraulic design guidance and planning conditions
  • Simplifies design responsibility
  • Is suitable for new build or retrofit schemes
  • Is ideal for use as part of a combined passive irrigation or active rainwater harvesting system and embraces the ambition of integrated water management

Kevin Bohea, Divisional Managing Director, stated ‘ACO is proud to bring this patented, market-leading system to the roofing industry. Using ACO RoofBloxx as the key attenuation product in the system, ACO can advise on the build-up of the system for projects and provide the hydraulic calculations needed for different roof types.’

Drainage design croppedFrom first drawing to final handover, preserving the design vision is never easy. Somewhere along the line there are bound to be extra costs and compromises. But there’s one critical part of the project that could reduce this, if considered early enough – drainage. Yes, drainage. With building performance under the spotlight and permitted discharge rates being restricted, managing water from roofs to sewers adds complex challenges. Attenuation requirements and hydraulic loads need careful consideration while drainage must be aesthetically pleasing. Yet these decisions often get left till way too late in the project.

Drainage designSo why does that matter? At ACO, our Drainage Design Services team believes early consideration of drainage solutions not only helps achieve a look that ties in with the design concept, but knowing the depths available for floor or balcony drainage from the beginning can have massive benefits for the end result. It allows us to calculate and advise on exactly the right system to handle the volume of water for the application, whereas late engagement may mean raising floor levels to accommodate different products – this disrupts other trades, costs more and compromises both timescales and design integrity. In other words, to preserve your design vision, look at drainage earlier.

Welding shots.00_09_33_03.Still006ACO has 75 years of experience in the manufacture of drainage systems.
