With over a decade of experience in energy-efficient systems, Ben has been an advocate for integrating innovative solutions like Dynamic Solar Shading (DSS) into modern building designs. Let’s start by understanding what brought you to focus on DSS.

Ben: My journey with DSS began about seven years ago when I was working on a large office tower project in mainland Europe. We were struggling with overheating in glass-heavy designs while trying to meet ambitious energy efficiency goals. That project introduced me to the concept of dynamic shading, and it completely changed the way I approach building systems. Seeing how a relatively simple automated solution could dramatically reduce cooling loads while creating a better experience for occupants was eye-opening. Since then, I’ve been passionate about showing others how DSS can transform not just buildings, but the way we think about daylight.

Why is DSS particularly relevant now, in your opinion?

Ben: The urgency has never been greater. Climate change is forcing us to rethink how we design and operate buildings. The built environment accounts for around 40% of global energy consumption, and cooling demand is expected to triple by 2050. Traditional systems alone won’t cut it. DSS addresses multiple pain points: it reduces HVAC energy consumption, enhances occupant comfort, and protects indoor finishes—all while leveraging natural daylight. This is not just a luxury; it’s a necessity in the fight against rising temperatures and escalating energy costs.

That’s powerful. You mentioned seeing the impact of DSS in Europe. Why do you think it’s been slower to catch on in the UK?

Ben: That’s a question I’ve often asked myself. In Europe, active façades with dynamic shading are almost standard in modern building designs. Regulations like the EU directive mandating Building Automation and Control Systems by 2025 are driving adoption. In the UK, the story is different—there’s a perception that shading is just an aesthetic add-on, or that it’s too costly to implement. I think we’ve also been hesitant to move away from manual systems, despite their limitations. There’s a real need to shift the conversation to highlight DSS’s long-term benefits, particularly its role in reducing carbon emissions and increasing building value.

So, what sets DSS apart from traditional manual shading systems?

Ben: DSS is a game-changer because it’s proactive, not reactive. With manual systems, you’re relying on occupants to make adjustments — lowering blinds when it’s sunny, raising them when it’s cloudy, and so on. But let’s be honest, that rarely happens. DSS automates those decisions in real-time, adjusting shading based on sunlight, temperature, and occupancy data. This not only optimizes energy performance but also ensures a comfortable environment for occupants without them having to think about it. It’s about finding the sweet spot between energy efficiency and visual and thermal comfort. We often overlook the impact DSS can have in the winter and its benefits to reduce heat loss through windows. This is why a system which is dynamic in its operation to deal with seasonal challenges is crucial.

It seems like DSS has clear energy and comfort benefits. What about financial concerns? Is it worth the investment?

Ben: That’s a question I get all the time, and it’s an important one. Yes, DSS requires a higher upfront investment than manual systems, but the operational savings and added value far outweigh the initial costs. For example, reducing HVAC strain can cut cooling loads by up to 60%. Beyond that, it extends the lifespan of HVAC systems, protects interiors from UV damage, and contributes to certifications like WELL, LEED, and NABERS. These certifications increase a building’s appeal to tenants, which directly impacts leasing potential. When you use tools like PRISM to model CAPEX vs. OPEX, the payback becomes very clear.

Can you share a specific project where DSS made a significant impact?

Ben: Absolutely. One of my favourite projects was with a university in London, Queen Mary University’s Blizard Building. We integrated DSS with their corridor lighting system, and the results were incredible: a 90% reduction in lighting energy use and a significant improvement in occupant comfort. It wasn’t just about saving energy; it transformed how the space was used. Another example I like to share is a multi-tenant office tower where we tracked cooling loads for tenants using DSS versus manual shading. The tenants relying on DSS reduced their cooling demand by 15,000 kWh in a year. That’s the kind of tangible, measurable impact we’re talking about.

Those are impressive results. Let’s talk about integration—how does DSS work with other building systems?

Ben: Integration is where DSS truly shines. Think of it as part of a building’s ecosystem. When shading systems, HVAC, lighting, and BMS are designed to work together, the results are exponentially better. For example, DSS can reduce cooling loads, allowing HVAC systems to run more efficiently. At the same time, it optimizes daylight, reducing the need for artificial lighting. These systems feed data into each other, creating a harmonious environment where energy performance and occupant well-being go hand in hand. It’s not just about saving energy—it’s about creating smarter, more connected buildings that adapt to future needs.

So what’s holding the industry back from wider adoption in your opinion?

Ben: I think it boils down to two things: misconceptions and inertia. Many stakeholders think DSS is complicated or only suited for high-end projects, which isn’t true. DSS is incredibly versatile and works just as well in smaller buildings as it does in skyscrapers. The other challenge is the mindset—many decision-makers still prioritise short-term savings over long-term value. We need to present clear, data-driven ROI models and success stories to change that mindset. Tools like PRISM and post-occupancy evaluations are key to breaking down those barriers.

Finally, what advice would you give to those looking to champion DSS in their projects?

Ben: My advice is simple: start the conversation early. DSS works best when it’s integrated into the design process from the beginning, not as an afterthought. Use tools like PRISM to model scenarios and present both the energy savings and occupant benefits. And don’t underestimate the power of data—case studies, post-occupancy feedback, and real-world examples can be incredibly persuasive. Engineering consultants in particular have a unique role in bridging the gap between design and execution. By advocating for DSS, you’re not just improving buildings—you’re shaping a more sustainable future.

Thank you for sharing your insights and experiences. It’s clear that DSS has immense potential to transform commercial building design. Any final thoughts?

Ben: Just this: the time to act is now. With rising temperatures, growing energy demands, and the push toward net zero, we can’t afford to rely on outdated methods. DSS is more than a technology—it’s a mindset shift. By embracing it, we can create buildings that work better for people and the planet. Together, we can lead the way to a brighter, more sustainable
