Get ready to Ramboll

Welcome to the Promised Land

Last week I hinted that I would be talking more about GEERS in this post, but breaking news – especially good news – trumps prior plans.

In case you didn’t see my tweet yesterday, Guelph’s Community Energy Initiative (CEI) got a big shot in the arm from across the pond. Danish District Energy leader Ramboll Group announced that it was setting up shop here. This is a tremendous economic development win for the city, but it’s only the beginning.

The origin of this news flash dates back to 2007, with the creation of Guelph’s CEI. The plan set a goal to use District Energy (DE) to produce significant energy efficiency gains for the city. (If you need a DE primer, I recommend my prior post Git ‘r Done.) At the time, this was a bold and, at least on this continent, unique proposition. Many cities had DE systems – some, like Veresen’s system in London Ontario, dating back nearly a century – but no city stated its intention to build out a citywide DE network.

Fast forward to 2013. As part of the implementation of DE, Guelph commissioned and published a District Energy Strategic Plan. This document stated a more specific goal – to meet at least 50% of the city’s heating needs using DE by 2041. This was even more bold and ambitious than the CEI objective, and placed Guelph’s plans even further beyond anything any other North American city had in the works.

Then in February of this year, a Guelph delegation consisting of me, Mayor Karen Farbridge, Chamber of Commerce President Lloyd Longfield, and Guelph Municipal Holdings Inc. General Manager Rob Kerr, travelled to Germany to participate in the Transatlantic Urban Climate Dialogue Plus. While in Berlin, our delegation met with a number of leading companies in the European DE market. Ramboll Group was one of them.

We described Guelph’s plans, and delineated how the CEI has enlisted a broad cross-section of the community and enjoys widespread and enthusiastic support as a result. We expressed our conviction that the DE market in Ontario, across Canada, and indeed in all of North America is on the verge of explosive growth. This growth will be driven by rising energy costs, increasing urban densification, and growing concerns over the effect of fossil fuels on our climate. We positioned Guelph as the gateway to a market that was about to blossom.

Our case was well received. Each of the three companies agreed to visit Guelph to explore the opportunity further.

In May and June, we hosted delegations from each company. Our European colleagues learned more about the details of our plans, and heard about the prior month’s visit by the Minister of Energy to announce two Combined Heat and Power (CHP) projects totalling 18 megawatts of electricity production. They also toured the city, saw the elements of the DE network that were already in place, and cased out the areas where we planned to continue building this new thermal energy utility.

We soon learned that our estimates of the cost and difficulty of implementing the system were out of whack. North American DE players are project focused, and the costs reflect this. Their European counterparts are program focused and are willing to offer prices with a long-term view. In other words, when ordering, say, 100 metres of DE piping as part of a program to lay over 100 kilometres, a North American company will offer a price for the 100 metre quantity; a European one will price based on the full 100 kilometres. By partnering with our new European friends, we stood to reap the benefits of significant bulk purchase pricing.

Another factor which was out of whack was our understanding of the ease of constructing a DE network. The first thing our Danish friends pointed out was that our roads are straight. So what? At first we didn’t understand why this was relevant. Of course our roads are straight. Aren’t all roads? And why does that matter, anyway?

European cities are, generally, ancient. At least more ancient than the automobile, which is the main reason for straight roads. European cities tend to be constructed along natural features, like rivers, deltas, lake shorelines, or seashores. Pipes are straight. Laying them along Mother Nature’s curves and bends is nightmarish, but it’s par for the course in the mature European DE market.

In North America, straight lines predominate – except for in the centres of the cities that were first settled on the east side of the continent. As you travel west, and as you travel out from the centre of older eastern cities, you find – you guessed it – straight roads. And since DE networks generally follow roadways (like other infrastructure such as water mains, sewer lines, buried cables, and so on), straighter means cheaper.

Another factor is the width of our roads. In European cities, at least in the downtown areas, drivability is clearly an afterthought. Negotiating some of the narrow lanes in anything larger than a Fiat Uno is a hair-raising experience. Installing any infrastructure means that the roads will be shut down for the duration of the work. Crews are lucky if they can find a route for the pipe that doesn’t interfere with existing services.

Our roads don’t feel that wide, but only because most of us haven’t experienced European ones. In some parts of Guelph, our Danish visitors gaped at wide roads, wide shoulders, and wide ditches – for the first time in their careers, they considered that they could run their pipe without halting traffic. It was a completely new and astounding idea for them.

The bottom line is that Guelph – and indeed all of North America – is the promised land for DE. It didn’t take long to reach agreement with all three companies. Ramboll is just the first – more good news is coming to Guelph, more economic growth, more jobs, and an exciting future at the forefront of a huge new market.


The Big Tent

If energy is the lifeblood of the economy, Guelph – like most communities – is haemorrhaging.

As of 2010, Guelph was spending $500 million per year on energy – electricity and natural gas for buildings and industry, as well as gasoline and diesel fuel for transportation. Where does that money go? A small amount stays in town, to pay for local gas stations, wires and poles, natural gas pipes, and so on. However, that sum is really just rounding error on the total bill. Almost all of the money leaves the city and never comes back. If we take electricity out of the picture, most of what’s left also leaves the province, since local sources of oil and gas are minimal. If the money leaves town, it doesn’t help anyone in town. Energy is a huge drain on the local economy.

If we do nothing, by the time 2031 rolls around, inflation and population growth will have at least doubled the annual spend. A billion dollars will be bleeding out of town every year.

It doesn’t have to be that way. All we need to do is make more, and waste less. We know we can do this, because others have. We can do it without sacrificing comfort and utility. Here in the City of Guelph we have a plan to get there, and we call it our Community Energy Initiative. It has two main parts: Local energy generation, and energy efficiency.

First, we rely almost completely on energy imports. Whether it is electricity coming from Bruce Nuclear or Niagara Falls, natural gas coming from shale deposits in Montana, or oil coming from Fort McMurray bitumen, virtually all the energy we use comes from elsewhere. To pay for it, money leaves our pockets and then leaves town.

However, new technologies mean that we can provide more for ourselves. Combined heat and power technology allows us to use the same fuel – natural gas to start, but eventually locally sourced biomass and biogas – to produce both warmth and electricity. (I like to call this getting a second squeal from the same pig.) Solar energy can also be used to produce both heat and electricity. District energy allows us to take waste heat from industry and supply it to homes, businesses, and other organizations so they don’t have to produce it themselves by burning natural gas.

We already have a combined heat and power plant supplying the West End Community Centre, and two more plants were approved back in April – one at Polycon in the northwest industrial park, the other in the Hanlon Creek Business Park. We have solar thermal panels above the back patio of the Wooly and on top of the River Run Centre and Fire HQ, and, solar photovoltaic panels on top of the Lawn Bowling Club and next to the Speedvale Water Tower. We also have a district energy network growing around the CHP plant in the south end that I already mentioned, and around the Sleeman Centre, which will soon provide heat to the next phase of the Tricar high-rise condo complex at the corner of Wellington and Mcdonnell. This is to say nothing of the DE system that’s been heating the University of Guelph for more than a hundred years. By 2041, half of Guelph’s heating needs will be supplied by district energy.

Second is the matter of energy efficiency. We use far more energy than we need to. If you look at a typical Canadian building through a pair of infrared goggles, it is a kaleidoscope of reds, oranges, and yellows representing embarrassingly large amounts of radiated, wasted energy. A European building will boast a few shades of cool blue. Leading European cities are nearly twice as energy efficient as Guelph is.

Europe hasn’t achieved this through some kind of sorcery, and it’s not as if Europeans are inherently more thrift minded or environmentally friendly. It all comes down to this simple motivating fact: Energy is very expensive in Europe. People, businesses, and other organizations have responded rationally to high energy costs. They have adopted policies, technologies, and behaviours to help them do as much, or more, with less. If we do what they have done, we can achieve what they have achieved.

I’m a fan of Earth Hour and I do my best to participate each year. However, contrary to the message that Earth Hour sends, conservation does not mean freezing in the dark. It just means figuring out ways to reduce how much we waste.

In the near future the City of Guelph will be launching a program called GEERS – Guelph Energy Efficiency Retrofit Services – to help overhaul our existing buildings and stop them from bleeding precious energy.

Earlier I mentioned that Europeans used a combination of policies, technologies, and behaviours to achieve leadership in the energy sector. Policies like the Community Energy Initiative and GEERS, technologies like district energy, and behaviours like participation in Project Neutral will help Guelph to get there too. I encourage everyone to learn more about Project Neutral and how it can help all of us to use less energy, save more of our hard-earned cash, and leave behind a smaller footprint.

It’s an understatement to say that there was an unexpectedly large turnout for the People’s Climate Mobilization on September 21st of this year. Some of you may have been on the steps of the old Guelph City Hall for the local version of that event. This demonstrated that many people care deeply about climate change. However, “many” is not the same as “all”. For many other people, climate doesn’t matter – or it doesn’t matter as much as jobs, wages, interest rates…in other words, the economy.

Climate is the small tent – rightly or wrongly, not everyone cares about it. The economy is the big tent – everyone gets money somehow, spends money somehow, and has to find a way to somehow make the two numbers match. To make meaningful progress on the climate issue, the conversation must move beyond the environment, and encompass the economy.

Energy is where the environment meets the economy. As a city, we can work together so that by 2031, we will be wasting far less energy, and producing far more of our own, and maybe, just maybe, keeping half a billion dollars right here in Guelph.

That’s a future we can all get excited about.

Postscript: The annual numbers for energy spend (present day and anticipated in 2031) were originally understated by 50%. This has now been corrected.


I spent this week at the penultimate meeting of the Transatlantic Urban Climate Dialogue (TUCD) in Germany, over and over hearing the term energiewende. Some of our hosts translated this as “energy change”, demonstrating characteristic German modesty. If I bought a Tesla Roadster, installed a solar array on the roof of my home to power it, ever after laughing at the price per litre posted at the local petrol station, and then referred to my accomplishment as changing a tire, it would be a similar understatement. Energiewende is no mere change. It is a revolution.

Visible signs of energiewende abound. Solar panels are a common sight on roofs of homes, factories, and institutions – the Free University of Berlin has several hundred kilowatts-worth of photovoltaics atop many buildings erected or annexed during the Cold War era when the city was hemmed in on all sides by the repressive and utterly democracy-free German Democratic Republic. As our train glided across the countryside at 200 kilometres per hour (120 mph) on the way from Berlin to Essen in the Ruhr valley region, we frequently squinted through the rain dotted windows to see farms of wind turbines rising above the landscape, sleek blades silently rotating with elegance and simplicity. From a hilltop in the Ruhr Valley city of Bottrop, a region once synonymous with coal mining, steel production, and air pollution, the silhouettes of massive power plants are visible on the horizon, their gargantuan stacks belching steam and carbon dioxide no longer, mute relics of a largely bygone carbon economy.

Energiewende makes itself felt in other, more subtle ways. Bathroom faucets often have no manual taps, but sensors that only dispense water when you present your hands – no absent-minded soul will ever leave the water running as they exit. Step off the hotel elevator onto your floor, and the hallway almost instantly lights up, activated by motion sensors that ensure all is dark when no one is there to benefit from the light. Step into your hotel room, and you will find all electricity extinguished – until you slip your access card into a slot on the wall by the door. On entering a Canadian hotel room, by contrast, you would find the lights blazing, as they would have been since the cleaner finished up many hours before. (This card slot has an added practical benefit of making sure I never misplace my room key.)

More subtle is the revolutionary way the room is heated. The hotel has no furnace. Hot water is piped into the building from a plant some distance away, a plant which takes waste heat from industry and puts it to work once more. (More on the idea of District Energy, or DE, in my previous post.) Alternatively, in places not yet served by the District Energy network, buildings are served by micro-CHP (Combined Heat and Power) units. As the name suggests, these devices provide both warmth and electricity. DE and CHP are both largely invisible, their components hidden away in basements or buried under pavement.

Finally, and least conspicuous of all, are the elements of the building envelope – energy-efficient windows, insulation, weatherstripping, and air exchange systems – which together help to make European buildings half as energy intensive as their North American counterparts. Our hosts in the city of Bottrop spoke of a number of housing projects which are “net positive”, meaning that the buildings produce more energy than they use. Some such projects are targeted at members of society on the lowest rung of the economic ladder – low-income earners and beneficiaries of social assistance. These people stand to be hardest hit by rising energy prices, and so stand to benefit the most from a dwelling that receives cheques rather than bills from the local utility.

When I think about my home in Ontario, I realize that the province has really missed the boat with its Green Energy Act. So much of the focus is on green energy generation – wind, solar, and biogas. There is an energy conservation component, but it is the poor cousin. The Feed-In Tariff (FIT) program has more than its fair share of flaws, but it stands head and shoulders above the SaveOnEnergy program.

Coal and oil are becoming ever more scarce and hence ever more expensive, and our environment cannot support their continued use. We need to replace all of our dirty energy generation systems with clean ones, make no mistake. This will be a hard hill to climb. But it will be far easier if the hill is shorter. At the same time as a revolution in green energy generation, North America needs a revolution in energy efficiency. District energy systems, combined heat and power, and building envelope improvements are all critical to shrinking the hill.

Our German TUCD hosts often spoke of everything they have yet to accomplish. They haven’t solved every problem – far from it. But they have made incredible progress. They have developed the technologies, the businesses, the public programs, and the social structures to make it happen. Through TUCD, they have been showing us how – we simply needed to ask.

In Germany, I’ve seen the hill. I’ve seen the way the German people are shrinking the hill at the same time as they are climbing it. And I am completely confident that North Americans can follow their lead.

We need our own energiewende. Our German friends are showing us the way.

Git ‘er done

Git-er-doneThat’s how a popular bumper sticker reads. To heck with correct spelling or grammar. Just do the job, no matter what it takes. Usually it’s on the back of a 4×4, and a muddy one. With a gun rack.

It’s a reflection of the North American psyche, and dates back to frontier times. You’ve got to get the job done, and you’ve got to rely on yourself. Your neighbour can take care of himself. If he asks for help that’s fine, but the starting out position is I can do it and I will do it and I will ask for help from nobody unless I am utterly desperate.

When the job that needs doing is heating a building, this mindset still prevails. Tell me what the best value for money is, and I’ll go for it. High efficiency natural gas furnace? Perfect. Git ‘er done. Electric baseboard heaters? Fine. Git ‘er done. Wood stove? That’ll do. Git ‘er done.

This snap decision has implications for the next two decades or more, because that’s how long many of these technologies will last. Natural gas is cheap now, but where will the price be in fifteen years? A building owner is choosing to be handcuffed to a particular fuel for a very long time.

The funny thing is, homeowners don’t actually want a furnace, a heat pump, a wood stove, nor is do they want natural gas, electricity, or firewood. What they want is heat.

What if they could just buy heat? What if they could opt to have a heat pipe coming into the house – much like that existing pipe supplying water, or natural gas, or that wire supplying electricity, or that cable supplying internet service? They wouldn’t need to fret about how the heat was generated. No more worries about the price of natural gas or whatever fuel source is in vogue. That’s someone else’s problem.

Oh, and while they’re at it, they can get rid of her big hot water tank. Why bother? Just use the heat coming out of that heat pipe to warm up the water, and Bob’s your uncle.

Sounds like a great idea, but obviously it’s fanciful. Who’s going to build a utility to supply heat?

Chances are that a European reading this is feeling awfully puzzled. What’s this guy talking about? We have a heat utility, and we have for decades. All across the continent, communities have built heat utilities. This type of business is built on a technology is called District Energy (DE).

Oh, DE exists in North America, too, but most people don’t know about it. Universities have been doing it for the longest time. My alma mater, the University of Toronto, has subterranean steam tunnels running all over campus – a fact that the engineering prank squad has long used as a convenient way to access buildings by means less obvious than the front door. You won’t find a conventional furnace anywhere on campus. One big plant supplies the entire university with heating and cooling, and those tunnels get the heat or the cold wherever it needs to go.

The Europeans have done it. Universities have done it. Why haven’t North American communities done it?

One big reason is that can-do attitude, which goes hand-in-hand with a going-it-alone attitude. Whenever a North American is trying to crack a problem, the first question they ask is not, “How can I team up with some other people to solve this?”

DE is all about teamwork. If my furnace runs less than half the time, and ditto for my neighbor, why don’t we just share one furnace? Half the capital cost, half the maintenance. Take that up a notch or two, and what do you get? An entire town or city sharing a furnace. That’s DE.

This kind of teamwork is foreign to most North Americans. Oh, there are long-standing traditions of mutual support in times of crisis, and of banding together for barn raisings, but the prevailing attitude is self-reliance unless there is no other option.

We can’t afford this attitude any more. A DE system is more than just a way to save capital costs by sharing our heating equipment. It is also more efficient than having a furnace in every building. Put another way, failing to implement DE is wasteful. In an age of dramatically rising energy costs and extensive harmful effects of greenhouse gas emissions, we cannot afford the waste that is inevitable where DE is absent.

There’s more. For heavy industry, heat is often a waste product, and it costs them a lot of money to get rid of it. By connecting a DE system to such enterprises, that heat can be spirited away for a nominal cost and supplied to residences, institutions, and commercial buildings. One man’s trash becomes another man’s treasure.

Finally, DE offers a platform for changing the way a community obtains heat. To start, the central heat source is likely a natural gas furnace or boiler. But through economies of scale, DE provides the opportunity to diversify away from a single fuel source – something that is difficult or impossible for someone going it alone. Large-scale geo-exchange systems can use electricity to supply heat, reducing dependence on the price of natural gas. Renewable biofuels like wood pellets can be used for fuel. Anaerobic digesters can convert agricultural waste into renewable biogas. Finally, solar thermal can be deployed on a scale that is far more economical than is possible for an individual building, exploiting a heat source that is free. Coupled with thermal storage technologies, a community can use DE to move toward heating that is 100% renewable.

It’s cheaper. It’s more efficient. It paves the way to a post-fossil-fuel future. DE is an idea whose time has come.

Git ‘er done.
