- Hotter Isn’t Always Smarter: The Hidden Cost of Cranking Your Dishwasher to 70°C
Most of us don’t give much thought to the temperature setting on our dishwasher. Eco. Normal. Intensive. We pick the one that sounds right and hit start. But what if that choice meant a tangible difference in your energy bill, and your carbon footprint? Let’s break it down. Heating Water = Energy. The Higher the… Read more: Hotter Isn’t Always Smarter: The Hidden Cost of Cranking Your Dishwasher to 70°C - Hand Calculations vs Software: Are You Engineering or Just Clicking?
Let’s get something out of the way first: We love software. We build it. We use it. Sometimes we even dream in Python. But every now and then, someone sends us a set of results that just don’t add up. Literally. When we ask how they got there, the answer is almost always: “Well… the… Read more: Hand Calculations vs Software: Are You Engineering or Just Clicking? - Why Low-Flow Fixtures Aren’t Always Sustainable
Low-flow taps and showers are often seen as quick wins for sustainability. They reduce water consumption, but that’s only part of the picture. In buildings with long pipe runs, especially in larger residential or commercial setups, low-flow fixtures can actually increase hot water energy use. Why? Because they delay hot water delivery, meaning users run… Read more: Why Low-Flow Fixtures Aren’t Always Sustainable - Engineering Better Buildings: Where Sustainability, Mechanical Design and BIM Intersect
As the pressure to deliver low-carbon, future-proof buildings grows, so too does the need for intelligent collaboration across disciplines. At the heart of this evolution lies the intersection between sustainability, mechanical building services design, and Building Information Modelling (BIM). Whether we’re tackling a healthcare facility, a heritage retrofit, or a new education hub, the process… Read more: Engineering Better Buildings: Where Sustainability, Mechanical Design and BIM Intersect - How Much of the World’s Electricity Comes from Renewables?
The global shift toward renewable electricity is well underway, but progress is uneven. The shift toward sustainable, low-carbon energy is critical for reaching net-zero targets, and MEP consultants are playing an increasingly important role in enabling this transition through smart building services design and infrastructure planning. As of the latest figures, around 30% of the… Read more: How Much of the World’s Electricity Comes from Renewables? - Electricity Generation Mix: A Global Comparison
As the world works toward net-zero targets, it’s important to understand how electricity is actually being generated today, and where the biggest shifts are happening. The diagrams below show the 2024 electricity generation mix for five major regions: United Kingdom, United Arab Emirates, United States, European Union, and China. Each Sankey diagram illustrates the flow… Read more: Electricity Generation Mix: A Global Comparison - Cracking Embodied Carbon: How TM65 Helps MEP Engineers Do Better
When it comes to carbon emissions in building services, attention is often drawn to operational energy, and how efficiently a building performs when it is being used. Another significant piece of the puzzle, though, is embodied carbon. This term relates to the greenhouse gas emissions associated with a product’s entire life cycle, which includes pre-use… Read more: Cracking Embodied Carbon: How TM65 Helps MEP Engineers Do Better - The Reality of Hydrogen Heating: Can We Retrofit?
At first glance, hydrogen can seem like an attractive heating technology, but are we underestimating the challenges that this technology poses? Is widespread retrofitting realistic? For a while, hydrogen was touted as being the future of heating, but its practicalities amongst our existing building stock remains a live debate. The majority of gas boilers are… Read more: The Reality of Hydrogen Heating: Can We Retrofit? - Substation Overload: Are Heat Pumps Putting Our Grid at Risk?
The UK and similar countries are well underway in transitioning to heat pumps, but it is not certain that consequences concerning the electrical grid have been properly considered. Gas boilers operate independent of the electrical grid, whilst heat pumps shift the heating demand completely into electricity. If this is scaled across entire streets, neighbourhoods and… Read more: Substation Overload: Are Heat Pumps Putting Our Grid at Risk? - The Green Energy Dilemma: Why Developing Nations Can’t Just ‘Go Renewable’
Carbon emissions within developed countries seems to be a continued hot topic, but there are less developed countries who are starting from points. The wealthier nations of the world had their Industrial Revolutions without sustainability restrictions, but now we are pushing decarbonisation agendas on developing countries as they struggle to meet their basic needs [1].… Read more: The Green Energy Dilemma: Why Developing Nations Can’t Just ‘Go Renewable’
