Barcelona, Singapore, Berlin, London, … What have these cities in common? They all want to become the first smart-cities. However, what do we mean by “Smart-Cities”? Have cities been not smart so far? Which concepts underlie this trendy locution? A smart-city is not only a connected city, where millions of data are crunched to offer new services, but also a resilient, energy and resource efficient and sustainable city. What a great program!
Because it represents a large field of experimentation EU Member States’ Governments can control and because local authorities have less and less enough budget to manage on a daily basis their assets, property asset is strongly exposed to the evolutions of the regulations on energy and climate.
75% of the global cost of the local and regional authorities energy consumption concerns buildings. Brought back to m², the annual costs in energy consumption of European towns property asset stagnate around 10 €.
In a previous post, we saw that it was easy to reduce street lighting energy consumption for almost zero investment. Today, we are going to visit 7 other efficient actions with very good payback time every cities should implement to reduce their electricity consumption.
- Redeploy street lighting points: In order to avoid the excessive number of lightings by acting on the spacing and the number of lighting points, these can be redeployed according to their buildings’ architecture and to our street maintenance services. The height of the lampposts can also be optimised to ensure an optimum response to the need for functionality, safety and attractiveness of our territories.
Regarding public lighting, the European norm EN 13201, not yet mandatory, sets up the illumination levels that need to be maintained in the different categories of public areas, essentially according to the level of safety. While respecting this regulation, conceivable (almost) free actions can be set up to optimize costs: change or modernize lampposts, regularly maintain the lighting lot, choose a rational use of public lighting, etc. Essential actions, detailed below, can help transforming our existing public lighting systems into effective public lighting systems.
Because the issues for local authorities are both environmental and economical, it’s necessary for them not only to create and divide wealth for everyone, but also master the budgets and face the urban sprawl problems, pollution, life quality and mobility issues. To obtain healthy and sustainable growth, managing energy demand and research for innovating and alternative solutions are proven to be central. Thus, any land use project, rehabilitation of buildings, or investment project should require to examine its carbon and energy footprint. Several reasons thereto:
