Type: Solution
This solution is tailored to local governments that have a mandate to approve and enforce municipal building regulations or bylaws that require and/or incentivize the use of SUDS and rain water harvest in private buildings and facilities in the city. It is applicable to new settlements as well as existing residential, commercial and institutional buildings and facilities.
This solution caters to local governments that have the mandate to manage stormwater in a city. It addresses the management of rainfall and runoff from public open spaces and transport infrastructure. The management of runoff from residential, commercial and institutional buildings are covered in a separate Solution as a different approach is required for areas under private ownership.
This Solution was tailored to Local Governments who have ownership and/or regulatory authority over the municipal water supply system. In this Solution, the Local Government takes a comprehensive approach throughout the different phases of the system’s project and useful life to decrease water-loss, both due to leakage and ruptures and to unaccounted consumption, from policy setting, project design, and project evaluation criteria to operation, monitoring, and maintenance of the system.
Architectural designs, construction practices, and technologies help optimize energy and resource use in buildings and provides benefits such as cleaner air, more comfortable homes and workspaces, and lower utility bills [1]. Improving energy efficiency in buildings aligns perfectly with the UN Sustainable Development Goals (SDGs) and the Paris Agreement by lowering greenhouse gas (GHG) emissions.
Sludge is the solid waste material, primarily organic in nature which settles out in the residential/municipal wastewater treatment process. When the dewatered and dried sludge undergoes anaerobic digestion, it generates biogas (mostly Methane) which can be collected and used as a source of renewable energy.
Cogeneration is the simultaneous production of useful heat and electricity from the same fuel source (IEA, 2009), also known as Combined Heat and Power generation (CHP). It is much more efficient than separate power generation through the combustion of fuels and usually a good choice for large consumers of both heat/cool and electricity such as certain types of industry and hospitals.
Geographical Information System (GIS) Mapping serves as a framework to organize and analyze data, and communicate information using the science of geography. It also reveals deeper insights into data, such as patterns, relationships, and situations, helping users make smarter decisions [1]. Before the introduction of GIS for resource assessment, site suitability was carried out through site surveys, paper maps, and other time-consuming, inefficient, and costly field sampling methods.
Pay-as-you-go (PAYG) is an innovative business model where energy service companies sell or lease solar photovoltaic (PV) systems, usually solar home systems (SHS), to customers in exchange for regular payments via mobile money, cash or scratch cards [1]. Due to the range of packages available, customers can choose from starter kits that supply a few lights and charge cell phones, to larger systems that can power TVs, radios, stoves and small fridges [1][2]. In some cases, if a customer cannot make payments, the energy service provider is able to switch off the system remotely, and switch them on again once payment is made [2
Green hydrogen refers to hydrogen gas produced through a process called electrolysis, using renewable energy sources such as wind, solar, or hydroelectric power. It’s called “green”” because the energy used in its production comes from sustainable and clean sources, resulting in minimal or no greenhouse gas emissions. The process of creating green hydrogen involves splitting water molecules (H2O) into hydrogen (H2) and oxygen (O2) through electrolysis. During electrolysis, an electric current passes through water, causing the water molecules to dissociate into their constituent elements: hydrogen and oxygen. The hydrogen produced in this way can be stored and used as a clean energy carrier in various sectors, such as transportation, industry, and power generation.”
Energy storage refers to technologies that capture one form of energy (usually electrical) when generated and store it as another (chemical, thermal, mechanical or electrochemical) for release when required [1]. Storage is essential for enabling the use of variable renewable energy (vRE) such as solar and wind due to its intermittent nature.
To control the impacts of climate change, governments are promulgating and reviewing regulations in order to achieve energy savings in buildings. One important strategy employed to make these laws and regulations effective is through energy efficiency labeling for buildings. A simple way to provide energy efficiency information, such as labeling, can create greater awareness and lead homeowners, tenants and developers to opt for more efficient buildings, ultimately reducing energy use and emissions.
Co-processing is a technology for reusing waste as raw material or fuel, mainly in energy intensive industries, where it combines material/energy reuse and the final disposal/destination of solid waste in a single operation. It can contribute to the conservation of natural resources by replacing conventional energy sources (i.e. fossil fuels) and other raw materials with energy and materials recovered from waste, as well as reducing the waste generated in the manufacturing process, and so its overall environmental impact.
