By Ed Palmer, CIBSE Knowledge Editor In a first for CIBSE, we released a Code of Practice on District Heat Networks earlier in the year that sets out what an engineer needs to know about installing and maintaining a heat network. But what is the code for, what is it about, and what is a heat network, anyway? To give us a hand, our Knowledge Editor Ed Palmer has written this handy guide to the code, which covers all this and more! What is a heat network? Heat networks (also known as district heating) supply heat from a central source to consumers, via a network of underground pipes carrying hot water. Heat networks can cover a large area or even an entire city, or be fairly local supplying a small cluster of buildings. Heat networks can be used to supply new buildings and existing buildings ranging from residential dwellings to commercial offices and public buildings. Indeed, a wider mix of building types is generally desirable as this provides a diversity of heat demands a

It's been a big year for the Society of Lighting and Lighting (SLL) and now, as an early Christmas present, we have a bumper blog from its President Liz Peck . Liz looks back on the last year in the run-up to, and start of, her Presidency For me, my presidency effectively began in January. I was mapping out what I wanted to do, what I was going to say during "the speech" in May. By that time, I'd already decided I wouldn't be wearing a suit. I'd sounded out a couple of trusted SLL friends with mixed response, yet I knew I was right: I don't "do" suits. If I could be elected in jeans, I could give my Address in them too. In January, my previous 'stalking' of the RIBA President Elect, Jane Duncan, came to fruition as she joined me and John Aston in Paris for the International Year of Light launch. In February, my personal quest to engage with the RIBA extended locally too as I joined the RIBA Yorkshire Awards judging team

As you've only just started painting you haven't yet decided the exact pose or expression that the famous face will take, but the detail you have put into her smile is stunning and likely to draw the crowds from miles around. Fast forward a year to 1504, and the painting is still under construction. You've been struggling for weeks with the tilt of her head, but finally your eureka moment arrives – you know exactly the angle you should use. Unfortunately, your new plan doesn’t fit with what you’ve created already, so you dig out a new canvas and have to start the painting all over again. 'La Gioconda' by Leonardo Da Vinci Finally, as 1505 arrives, you'

As part of the historic CIBSE YEN trip to Hong Kong, which saw all the major YEN groups meet together for the first time, CIBSE President-elect John Field travelled with them to speak at the YEN Conference. After the trip, John writes about the experience, and those to whom the YEN group is now indebted. The phrase ‘trip of a lifetime’ is an overused one – after all, it’s not often that going abroad on business or on holiday can actually change the course of your career or your life. But in the case of the young engineers who set off last Sunday on their visit to Hong Kong, those are exactly the kinds of stakes were talking about. The trip was organised by the Young Engineers Network (YEN), a worldwide group of regional centres stretching from Scotland to Australia that acts as a forum for ideas and a support network for engineers just starting out in the industry. The Young Engineers and I thank our hosts for a great trip This particular trip was even mo

Here are our Young Engineers' thoughts from Day 4! Day 4 Jason Smith, FHP Engineering Services Solutions So today takes us to Macau, the part of the trip I have been most excited about, as I knew we were visiting casinos! I'm not a bit gambler but after going to Las Vegas I became fascinated by the complexes for the their sheer size and complexity with many different activities going on at one time. We arrived at the Venetian hotel and instantly it brought back memories of Vegas, and the similarities were clear, I was looking forward to having the chance to see the inner workings of t

Day 2 Karen Settle, Pick Everard After a stressful few hours and a more than memorable flight setting off at 2am Hong Kong time we were pleasantly surprised to check in to our stunning hotel, and the first night was a taster of what's to come on our very intense itinerary. Here we are in Venetian hotel (Macau) and casino plant room one of the largest of its kind with over 13 number chillers installed based in banks to provide resilience based on the schematic at least 11 of these bank

The HK Branch and YEN HK have been working tirelessly to develop a seamless programme

As part of our coverage of the CIBSE Young Engineers Network trip to Hong Kong from Sunday 15 November, we are featuring a series of blogs from those on the ground as well as bringing you the best photos and social media activity. In the run-up to Sunday, we spoke to an employer about why they are sending their young engineer on the trip. S teve Dixon, Director of JDP explains : Why would an employer agree to allow a young engineer to take five working days to attend a conference in Hong Kong when we are very busy? That is the question that we pondered over when David Mather asked if we would provide assistance to him so that he could attend the CIBSE YEN Conference in Hong Kong in November. We already allow David to have time to attend CIBSE YEN events and to fulfil his role as Chair of YEN London and we have a policy at JDP of supporting the development of young engineers.   However, this would be different.
