  1. Solar Buildings: Success through integration Meli Stylianou, Solar Buildings Research Network

  2. VISION Development of the solar-optimized building as an integrated advanced technological system that will approach on average the zero-energy target and be cost effective. Advanced does not mean complex; it brings together “low-tech” passive solar technologies that appear simple but generally require careful design with “high-tech” active envelope elements such as motorized blinds and airflow windows with photovoltaics and smart predictive control systems. Solar-optimization requires that the solar technologies are optimally integrated into the design and operation of the building.

  5. The many aspects of solar energy

  6. Integrationimplies the design and operation of the building/house as a system: It goesbeyond the installation of a solar system on the roof. The envelopeevolvesinto an energy conversion system and an integral part of the building’senergy system. The system becomes the building, and itsoperationbecomescritical to itssuccess. What is «integration»…?

  7. Key features of Alouette House • Passive Solar Heating • Large south-facing windows (RSI 1) • Passive Charge Concrete Slab & Brick Wall • Motorized Blinds • BIPV/T • PV panel Cooling • Drying Clothes • DWH heating • Ventilated Concrete Slab heating • Geothermal HP • Forced-Air Space heating/cooling • DWH heating

  8. Innovation: BIPV/T roof construction in factory

  9. ECOTERRA EQUILIBRIUM HOUSE Integration – BIPV and passive solar Controls – how to get everything working well and with the passive solar design Unique hollow-core floor slab design for storage of heat from BIPV roof Alouette Homes, Concordia (Athienitis and four students), Regulvar

  10. Integration is the key • Integration of solar systems provides more than the sum of the individual contributions: • Photovoltaic (PV) panels mounted on the roof and façade typically convert 6-18% of the sun’s energy into electricity, • 50-70% of the rest can be extracted as heated air from the PV panels while • 10-30% can be utilized for daylighting with semitransparent systems. • Combined solar energy utilization efficiencies of up to about 80% can be achieved if proper integration strategies are implemented. Indeed, there is the potential for a building to achieve, on average, zero energy consumption.
