A conversation with Wilco Burggraaf, Principal Lead Green Software Engineering at High-Tech Innovators, exploring the practical side of green software engineering.In this episode, we discuss:How Wilco transitioned into sustainability after 20+ years in ITBuilding a 700-member Green Software Foundation meetup community in the Netherlands in just 8 monthsThe complex relationship between energy efficiency and compute efficiencyCreating tools to measure CPU utilization at millisecond resolutionWhy idle time and underutilization are the "forgotten things" in sustainabilityThe embodied carbon impact of development practicesHow AI is changing how companies think about software materialization in sustainability reportingPractical approaches to integrating green software tools into CI/CD pipelinesKey Points:- Not all code lines have equal environmental impact- The challenge of attributional vs consequential carbon accounting in serverless- Why "build to last" should be a core principle of sustainable software- How temperature impact on devices affects battery life and overall sustainabilityRecorded at VoxxDays Amsterdam, this conversation bridges theory and practice, showing how green software engineering is moving from research to real-world implementation.Links:https://www.hightechinnovators.nl/ (Dutch)https://www.meetup.com/green-software-the-netherlands/

In this episode, Oliver speaks with David Kohnstamm from Leafcloud about a fundamental shift in how we think about data centre locations. Forget remote warehouses - the future of sustainable computing lies in nursing homes, apartment complexes, and anywhere with constant heat demand.David reveals why traditional data centres waste enormous amounts of energy cooling servers, while distributed computing can turn that "waste" heat into free heating for communities. The key insight? It's all about matching your infrastructure to locations with 24/7 heat requirements.- Why nursing homes are perfect data centre locations (constant heat demand, 24/7 operations)- The fatal flaw with office-based edge computing (weekends, evenings, seasonal gaps)- How Leaf Cloud delivers servers that literally pay their rent with waste heat- Why PUE metrics actually reward throwing heat away- The difference between heat recovery that works vs. heat recovery that fails- Why hot water heating beats space heating for consistent demand- How distributed computing can scale to meet 50% of residential heating needsThe Bottom Line: Location strategy for data centres should follow heat demand patterns, not just connectivity or land costs. When you place servers where constant heat is needed, you solve both sustainability and cost challenges simultaneously.#SustainableTech #DataCentres #GreenComputing #HeatRecovery #DistributedComputing

Please note: We apologise for the audio and video quality in this episode - as Oliver mentions, "we're a bit hesitant here because we're kind of squatting in part of Tech Show London trying to record a conversation" - but we couldn't miss the opportunity to capture this discussion!In this episode of Architect Tomorrow, we catch up with Mark from Deep Green at Tech Show London to discuss their groundbreaking approach to data centre sustainability.Deep Green operates data centres with a crucial difference - they capture all the waste heat from computing and provide it free to industry and district heating systems. As Mark explains: "97% of the electrons that go into a computer come out as heat" - turning data centres into efficient electric heaters that serve dual purposes.Key topics covered:- How heat recovery makes data centres 20% cheaper to cool and operate- The role of AI and high-density computing in creating more waste heat- Why this model becomes economically attractive above 20kW per rack- The potential to heat 80% of the UK through district heating systems- The intersection of climate emergency and digital infrastructureMark shares insights on market adoption, explaining: "we're unfathomably cheap if you do this you just make yourself richer" and discusses how sustainability credentials combined with superior economics are driving customer interest.This conversation offers a fascinating perspective on how the AI revolution's power demands could actually accelerate decarbonisation efforts across Europe.

In this episode, Oliver Cronk talks with Ron Kersic about "Futuring Architectures" and how architects can navigate today's rapidly changing digital landscape.

Ron, a self-described "recovering programmer" now at ING's Tech Strategy group, discusses his journey from early programming to enterprise architecture. He explains his concept of "Futuring Architectures for Sustaining Transitions" (FAST) and why he rejects traditional "target states" in favor of a "cone of possibilities" approach.

Key topics include:

• Ecosystem thinking beyond organisational boundaries
• AI's transformative impact on technology creation
• The changing role of architects in navigating uncertainty
• Systems thinking and sustainability across technological and natural ecosystems
• The need for diversity in architecture teams

A special edition of Architect Tomorrow covering the Green IO London conference in September 2024. It was an exciting day, and whilst we couldn't capture everything, this episode gives you a taster of what was shared on the day - with some clips from the talks, the panel on AI, and interviews with some of the speakers and of course Gael Duez!

In this episode of Architect Tomorrow, host Oliver Cronk is joined by Isabelle Chatel de Brancion, Business and Innovation Lead at Geovation, Ordnance Survey's innovation hub. Isabelle shares her unique perspective as a former building architect turned geospatial innovator, drawing parallels and contrasts between the worlds of building architecture and technology architecture.
