Draft:Smart Readiness Indicator

From Wikipedia, the free encyclopedia

The Smart Readiness Indicator (SRI) is a European Union rating of the smart readiness of buildings (or building units) in their capability to perform three key functionalities:.[1]

  • optimize energy efficiency and overall in-use performance
  • adapt their operation to the needs of the occupant
  • adapt to signals from the grid (for example energy flexibility)

Criticism

[edit]

The EU activity does not consider rebound effects [2], which can amount to approx. 5%. A quarter of the Home Automation markets is in the luxury sector [3]. The inequality of the energy consumption [4] is also caused by bungalow style buildings with much higher floor area per person. Distributed intelligence like electronic thermostats suffer from the location of the temperature measurement near the radiator, not knowing about the presence in the room. Assuming that such temperature adaptation to occupancy is possible, the efficiency gain depends on whether heating up after non occupancy needs more energy than is saved by lowering the temperature [5]

New definition

[edit]
  • allow monitoring of the HVAC in order to optimize operation and plan decarbonization
  • allow change of temperature and air exchange etc. and give feed back if set points exceed energy efficient operation
  • ensure shading and thermal insulation meets the demand of a given usage scenario
  • implement model predictive control minimizing CO2eq intensity, switching heating, cooling, domestic hot water (DHW)
  • allow for master shut-off when leaving the building
  • allow comparison of energy demand after weather correction
  • use existing hardware like router to minimise Life Cycle Assessment emissions

Basic requirements

[edit]

Buildings and Apartments shall allow users to regulate the temperature, shading and temporary insulation. The energy systems shall give feedback about their state, the actual (specific) energy demand and allow changing set points easily.
