The overall objective of the project is to demonstrate and validate new technologies, concepts, and systems used in EE-HIGHRISE project, in order to test and assess the technological and economical feasibility of innovative energy solutions in high rise demo building Eco Silver House. Demo high rise building Eco Silver House is located in the city centre of Ljubljana. The net total area covers the surface of 23.455m2 of which approx. 12.870m2 belongs to net heated residential area (demonstration part of the building). The project foresees 17 floors, with 4 basement floors. The residential area includes 128 passive flats and solely the residential area is the proposed demonstration area. The EE-HIGHRISE basic principles of sustainable high building are reflected through integrally planned saving project of energy efficiency, also with renewable energy sources: excellent thermal isolation and sound isolation of walls, high quality ventilation system by recuperator, sun protection, extremely rational air-conditioning, intelligent steering and handling of electrical and mechanical appliances, machines and tools, ecological materials, use of rain water, sun electric power plant, green roof etc. The result of all above mentioned is achieving: a passive standard (PHPP07) with the use of energy for heating 10kWh/m2 a year and Energy class A (energy identity card) with annual need for energy 2.4kWh/m2a. The most relevant innovative element of EE-HIGHRISE is the integration of building envelope solution, HVAC system, intelligent holistic control system and RES resulting in passive standard for a high rise building of 11 storeys with 128 apartments while still being cost effective.
