Don’t Waste the Waste: the Economic Opportunity to Harness Waste Streams, Reject Heat & Integrate Local Energy Sources
. of ecosystems are now damaged or being used unsustainably
What is District Energy? Historically, the fundamental idea of district energy has been simple; reusing and sharing surplus energy between buildings that would otherwise would be wasted. produce steam, hot water or chilled water centrally involves shared heating or cooling infrastructure to a group of buildings it can serve from as few as 2-3 to as many as 2000 buildings electricity is often produced by a combined heat and power and the "reject heat" that results from burning fuel to produce electricity is used in the DES Modern district energy can encompass much more: is not exclusively about heat or surplus energy district solar PV system can serve several buildings, even if no heat involved about local production and consumption, only not at the building level..
. The Opportunity: Why District Energy? The growing cost of energy; concern about energy security; and the threat of climate change are increasingly focusing attention onto district energy systems. The top three reasons cities are choosing district energy: CO2 Mitigation Potential: Delivers the Cost Effective and Deep Reductions A Way to Capture Waste Streams, Reject Heat and Local Energy Resources to Spur Economic Development Using City Authorities: Area of Climate and Energy Action in which Cities have the most Control to Enforce Policy Targets (e.g net zero/plus building codes) “A lot of cities are frustrated by the fact that they don’t have their own utility and beholden to the state run energy. What is so great about the district energy approach is that every city is the land-use authority and can use their capacity in their land use approvals to require district energy projects” Vancouver, Canada
District Energy Benefits Resilience and Adaptation energy security and local production not solely dependent on a single source or imported fuel supplies reduced reliance on potentially vulnerable centralized grid (underground pipes safe from weather storms) Recovering heat sources enable chilled water for cooling, avoiding the need to use electricity and/or new fuel inputs. GHG Mitigation Potential at Least Cost can avoid over 35 GT of CO 2 emissions by 2050 at least cost, and deliver 58% of CO2 emission reductions required to stay within 2-3°C emissions to the environment are approximately 30% less conventional district cooling can reduce CO2 emissions by 75% vs. electrical chillers improved local air quality and health Energy Efficiency Gains and Financial Savings up to 80-90% efficiency primary energy savings of 30-45% compared to conventional generation reduce network losses and defer/reduce upgrade cost for distribution grid achieve net zero energy buildings in a cost-effective way Local Economic Development diverse business and finance models incl. public, private, cooperatives shows an ROI of 8-10% and cost competitive with traditional heat /power more optimal on-site RE strategies balance renewables, store and sell excess electricity generation
Bromölla is a small town in Sweden that uses surplus heat from the local pulp and paper industry to provide secure, inexpensive and climate friendly heating to half the population. Toblach is a community in Italy that launched a biomass-based district energy cooperative with 14MW of heating capacity and 1.5MW of electrical capacity from organic biomass CHP, serving 900 customers.To strengthen the link between energy use and local, family-owned forests, the system pays local farmers 75 percent more than the market rate for biomass feedstock. Rates have remained flat for 15 years Masdar City’s district cooling system – involves pumping chilled water from central plants to buildings across a wide area – will be up to 60% more efficient than conventional air conditioning, achieved by combining state of the art technologies including geothermal and solar thermal energy, and chilled beams/floor slabs. Kidapawan in the Philippines approved construction of the city’s third geothermal district energy plant in 2012. Recently district cooling systems have also been developed in cities in Saudi Arabia, Qatar and Malaysia, Hong Kong and Singapore. District Energy St. Paul has shifted from coal to local urban wood waste as primary fuel and is integrating solar thermal to provide low carbon heating and cooling to the majority of buildings in the Minnesota state capital, avoiding over 240,000 tons of CO 2 emissions annually. The Opportunity: Viable at Any Scale
Energy Mapping and Infrastructure Planning starting point to assess opportunities, establish economic and technical viability, tailor policies and business models, engage stakeholders and inform an overarching strategy Land-Use Policies help aggregate, provide or guarantee minimum demand for developments, provide investor security, alleviate financial risks and give guidelines for urban development plans to consider district energy community energy plans service area bylaws designate areas for district energy service providers public and private rights-of-way and easements for DES installations connection mandates and compatibility requirements development cost charges zoning to encourage high density and mixed use Stakeholder Engagement Policies bring together the different actors necessary for DES deployment (capacity building) and facilitate community buy in (awareness) training programs and designation of central office or “champion” communication campaigns and outreach on benefits and suitable sites coordination across departments and with neighbouring cities and Policy for DES: From Energy Mapping to Land- Use
Call for Input and Review: UNEP, ICLEI, UN Habitat Guidebook Visit the UNEP website (link provided to private area) to provide input on best practice policies, good practice examples and recommendations for the excerpt and final publication Feature your cities or project as a best practice See your questions and concerns addressed Supporting a larger effort on low-carbon development on the city level –and will also serve as guidance for a “cities for cities” twinning process on energy. Synergies are being explored with the UNEP Global Initiative on Resource Efficient Cities (GI- REC) launched in June 2012 at the Rio+20 Summit. UNEP, UN Habitat, ICLEI Guidebook: “Policies for District Energy Deployment in Cities”
GI-REC: Global Initiative on Resource Efficient Cities. Objective: To enhance the quality of life in urban areas, in particular in rapidly growing cities in developing countries, while minimizing resource extraction, energy consumption and waste generation, and while safeguarding ecosystem services” District energy helps cities achieve resource efficiency through reduced energy use, better waste management, and the provision of green infrastructure. District energy systems resemble the circular metabolism approach of natural ecosystems that use outputs of various processes as inputs for others such as allowing in the recovery of heat, otherwise wasted.

“Cities 4 Cities” to Accelerate DES Deployment The “Cities 4 Cities” Twinning will bring together champion and learning cities to: share their policies and experiences assist each other in policy planning and DE strategy development engage in a collaborative process with public and private sector stakeholders. Private Sector will offer energy audits to cities interested in advancing DES Global and local businesses can commit to participation in collaborative policy roadmap development and participation in pilot projects. Partners already Include: Vancouver, CA; London, UK; Copenhagen and Denmark; Accenture; Ramboll, Danfoss; Siemens, UN Foundation; UN-Habitat, ICLEI
Invitation to Join Public-Private Collaboration on DES Building on this momentum, UNEP, UN Habitat and ICLEI are working towards a “summitable” commitment on district energy that could be put forward to the SG’s Climate Summit U.N. Secretary-General Ban Ki-moon appointed former New York City Mayor Michael Bloomberg as his special envoy for cities and climate change. Ban Ki- Moon said Bloomberg will assist him in: “consultations with mayors and related key stakeholders, in order to raise political will and mobilize action among cities as part of his long-term strategy to advance efforts on climate change.” Inviting more actors on board as partners to this “Cities 4 Cities” process for DES deployment in support of the Sustainable Energy for All initiative (SE4All), as the member of the Advisory Board on the level of the UNEP ED and as a co-lead on the SE4All High Impact Opportunity on Energy Efficiency in Buildings This is in light of the UN Secretary General's SE4All initiative, which has three main objectives: universal access to energy, double the share of renewables in the global energy mix, and double the global rate of energy efficiency.
