Dr. Oliver von Quast is a partner of NION, angel investor and serial entrepreneur, with expertise and longterm experience in the utilities and cleantech sector, and provides some ideas we have put together.
“The greatest threat to our planet is the belief, that someone else will save it.” That’s why in such an early stage we have already put together some ideas for sustainable facility and energy management.
- 2nd use concept for food not used in restaurants, e.g. for homeless or other people in need
- Re-use/deposit concept for all packaging (e.g. all food and beverage packings)
- Waste collection only with emission-free vehicles (utilizing latest autonomous driving systems)
- Recycling on site (e.g. composting of organic waste)
- Separate drinking water and grey water cycle for non-food-related needs (e.g. toilet flushing, plant irrigation)
- Roof gardening
- Biodiversity concept combining local plants/animals with Japanese plants/animals
- Storm water collection (rain water ponds to be integrated in the landscape design)
Thanks to very good insulation, heat energy is hardly needed in modern buildings. Our generation can cover almost all the heat demand in the future: centralized electricity storage systems support the balancing of demand and supply, as well as o ering energy-e cient applications. Possible future ban of fossil fuels will push the use of renewable energies for heating applications. Furthermore, the continuously increasing share of electricity generated by renewables requires more exible power consumers.
So, we believe that as a part of the “sector coupling”, electricity is becoming a “universal energy carrier“, thus electrical energy will become cheaper and more accepted for heating in the near future. Electricity will play an important role by providing and managing exible loads (e.g. negative balancing power) especially for large living quarters.
We will therefore renounce the centralized provision of centralized hot water and water-based heating-networks. Instead, hot water and heat will be generated just on demand by new generations of highly efficient electrical heating systems.
There should not be an energy management concept without utilizing a Smart Grid. Smart Grids can add a lot of value when a couple of di erent types of renewable energy generators provide energy to many users. This is even more relevant, when different user profiles (living, working, leisure, etc.) do exist. Smart Grids can be of advantage in the area of measuring, billing and the control and optimization of electricity producers and consumers.
Above that, producing energy on-site offers several new business models to provide green energy directly to tenants (e.g. “Mieterstrom”). As real estate companies and large lessors will take over the role of utilities in the near future by providing not only living space but also services like energy production and provision and will thus gain additional value by grid services. This covers advantages for both, tenants and lessors: low maintenance costs, transparent and flexible green energy and heat generation for reasonable costs.
The technologies mentioned in Pt. 2 provide a rough overview of what can be conceivable.
