O webinar SEDA Solar Seminar #4 – Building Integrated and Intelligent Solar Design, que decorreu a 10 de outubro 2022, contou com a participação do LNEG com a apresentação do caso de estudo Solar XXI, An Example of Integration of Solar Facade Toward a Nearly Zero Energy Building, por Helder Gonçalves e Carlos Rodrigues.

This webinar will introduce case studies of two buildings with integrated PV, the Solar XXI in Portugal and the Helios House in UK.

Two short presentations will be followed by Q&A and discussions.

1. Solar XXI, An Example of Integration of Solar Facade Toward a Nearly Zero Energy Building by Helder Gonçalves & Carlos Rodrigues, Energy Laboratory of Energy and Geology.
   This presentation focuses on the integration of a Solar PV Facade within the design of an office building. A convective heat recovery system, covers part of the energy needs for heating, and the building has a ground cooling system, which provides the cooling for summer periods. The building follows the principles of a Passive Design; south facing and well insulated, which together with the low energy use of the building and the integration of the PV in the façade and the car parking, enables the building to be a good example of NZEB in Portugal.
2. An introduction to Helios House – a fully integrated solar installation by Chris Askew, Founder, ASKEWCAVANNA Architects.
   Helios House is a headquarters office and training centre for Solarsense UK, a company delivering renewable technology installations. The brief was to design it as a demonstration house to show off renewable technologies. The building is design to Passivhaus level of airtightness and insulation. It features a Paul Novus 450 MVHR, underfloor heating powered from Ground Source Heat Pump, Loxone smart home automation, and a fully integrated 12.85kWp solar pv roof comprising the whole of the south facing roof, incorporating feature roof lights over the main space.
