Money Saving Boiler Challenge  Environment

This campaign focused on hot water heaters that provide water on demand for heating a home and also for cooking and cleaning. Lowering the water flow temperature from 80°C to 60°C could save a 9% reduction in total gas use, but only one in ten households had adjusted their water flow temperature in the previous year. Nesta developed and pilot tested an online tool to help occupants lower their own water flow temperatures. 

In 2022 and 2023, over 214,000 people used the online tool and indicated that they had turned down their water flow temperatures. Based on Nesta’s research, that would save around 200,304,000 kWh and £20 million on energy bills and would avoid the release of 37,000 tonnes of CO2 per year. The campaign created £33 of savings for every £1 spent on marketing.

Proffers for New Development in Fairfax County, Virginia  Environment

Fairfax County established Transportation Demand Management (TDM) requirements (“proffers”) for new development that would have significant traffic impacts. For buildings within the urban centre of Tysons, trips had to be reduced between 25% and 65% during peak hours, depending on the size of the building and its proximity to the Metrorail stations. The county proffers required large new properties to annually monitor trips, conduct tenant commuting surveys, and show that they were meeting their trip reduction goals. They also had to conduct surveys every three years. Over seven years, 13 such developments generated 63% fewer trips, which was 34% beyond their goals. For the office buildings, this was likely at least partly a result of more people working from home during the COVID pandemic.

Landmark Case Study Smart Trips Austin  EnvironmentHealth

Smart Trips Austin encourages residents of Austin Texas, USA to take multi-modal transportation options (walk, bike, ride transit, and share rides) more often, rather than drive alone. The program focuses on personal interactions — educating individuals on their options and overcoming barriers to multi-modal travel. Smart Trips reinforces this new information using community-based programs such as learn-to-ride classes, transit instruction, and group walking activities. Initially, the program targeted residential neighbourhoods of Austin Texas; each year a different area was targeted. In 2020 the program expanded to city-wide and began to segment using a Stages of Change approach. In 2021, it started targeting residents who had recently moved to or around Austin. Smart Trips Austin averaged a participation rate of 5-10% of households contacted, a 5-10% reduction in drive-alone trips among participants (about 41,000 vehicle trips per year), and a corresponding 5-10% increase in active and shared trips. This account of the program was designated a Landmark case study in 2023, making the City of Austin one of the few governments with more than one program designation.

Landmark Case Study Southern Nevada Water Authority's Water Smart Landscapes Program  Environment

As climate change leads to more drought situations, it will be important to understand how to best promote water conservation. Southern Nevada Water Authority’s Water Smart Landscapes (WSL) program pays homeowners to replace their non-native, ornamental lawns with plants and landscapes that use less water because they are better adapted to their dry climate.

The Reduce Your Juice program was designed to be fun, easy and impactful. On the exterior, it appears as a simple, fun and easy experience of games and gamified activities, communications, community, and rewards. However, below the surface lies a sophisticated intervention developed through the application of formative research and theory and implemented by a team of multi-disciplinary experts from the energy, social marketing, behaviour change, digital insights & technology, research, and social sectors.

Landmark Case Study How Copenhagen Became a Cycling City  EnvironmentHealthSafety

What makes a great cycling city? How did the medium-sized City of Copenhagen get its citizens to cycle to work / school 49% of the time? While topography and climate are significant influencers, safety, supportive infrastructure, and promotion also played key roles. Copenhagen increased cycling by making it safer, easier, and more convenient. This case illustrates the power of piloting alternative enhancements on an ongoing basis to further reduce barriers and increase benefits, based on regular surveys, traffic data and safety data. It also features a transparent planning process - the Bicycle Account – a research, evaluation, promotion, and citizen engagement tool used every two years since 1996. Designated a Landmark case study by our Transportation peer selection panel in 2022.

Landmark Case Study Paris Reduces Car Use, Boosts Walking and Cycling  EnvironmentHealthSafety

Paris is an inspiration for large cities around the world, having reduced car traffic in its core (Ile de France) from a mode share of 12.8% in 2010 to 6% in 2020. How did Paris get to be one of the cities in the world with the lowest mode share for single occupant vehicles? The city is comparatively dense and has one of the top subways in the world. But what is most striking about its transformation is the increase in cycling and walking during this period – they increased from 55.4% in 2010 to 68% in 2020. Numerous programs offered by three levels of government explicitly prioritized bicycles over cars and reduced on-street car parking to make room for bike lanes. They taxed and restricted more polluting vehicles, and gradually phased them out, while providing a conversion bonus for the purchase or lease of electric-assisted bicycles and cargo bikes. In addition, car ads had to include messages promoting greener methods of transportation, and incentives were provided for bike repairs and tune-ups. Designated a Landmark case study by our sustainable transportation peer review and selection panel in 2022.

Landmark Case Study Opting Out in Germany for Non-Renewable Energy  EnvironmentHealth

While many people in Germany say they would use green energy if presented with a choice, very few consumers do so. In contrast, most people have been using green energy in a few German municipalities where citizens have had to opt out for non-renewable energy supplies rather than having to opt-in to get renewable ones. This case study also illustrates the connection between green power choices and clean air / environmental health, and the value of randomized control trials (RCTs) for measuring program impacts. Designated a Landmark case study by our Building Energy peer review panel in 2022.
