“…The results of these case studies will be disseminated in two ways. First, four of them are being presented at the EuroSun 2010 conference [19][20][21][22] and one of them is being planned for the ASHRAE 2011 summer meeting. A Sourcebook containing all major STB work will be also be published.…”

The design of net-zero energy solar buildings (NZESBs) presents a challenge because there is no established design strategy to systematically reach this goal and many of the available building energy tools have limited applicability for such advanced buildings. This paper reviews current design practice and tools for designing NZESBs through a literature review and a survey. It also discusses modelling issues and presents the procedure used in several redesign and optimization case studies of existing NZESBs that Subtask B (STB) of the IEA SHC Task 40/ECBCS Annex 52 project "Towards Net Zero Energy Solar Buildings" is performing. The case studies will identify gaps in existing tools and help develop strategies for the use of design tools in establishing near optimal NZESB designs.

“…The ZEBRA2020 project has been developed to monitor the market uptake of nZEBs in target countries and across Europe, and to provide data and recommendations on how to reach a high level of building performance [26]. Pascual et al [27], in the contest of the ZEBRA2020 project, and Cellura et al [28,29], report monitoring energy data for the "Leaf House", a nZEB located in Rosora (Ancona, Csa/Cfa -under the Köppen climate classification), Italy. The reported building's energy production by PV is 53.77 kWh/m 2 /year, whereas the total energy use is 91 kWh/m 2 /year and the use of electricity for heating is 27 kWh/m 2 /year.…”

Over the last decades, the reduction of the energy use in the building sector has become a topic of major investigation and policy development worldwide. Guidelines have been defined to drive governments and building construction stakeholders towards the retrofit of the existing building stock and to the construction of new highperformance buildings. However, availability of operational data is often limited, especially when it comes to high performance buildings in warm climates, although it is essential to define design approaches targeted to energy efficiency, to design smart energy grids and demand-response oriented energy programs. Buildings, such as living laboratories, may offer opportunities to implement and develop energy databases, to provide benchmarks and to study occupant behaviour under different operational conditions. The paper investigates the energy and thermal comfort performance of a residential building in the Mediterranean climate. The building, certified as Passivhaus and equipped with an advanced monitoring system, allows to test different control strategies, to study occupant behaviour and to provide real time operational data. In particular, the data analysis showed a positive energy balance on yearly basis, i.e. an energy use of 59.7 kWh/m 2 net/year vs. an on-site energy generation of 76.0 kWh/m 2 net/year. The energy breakdown highlighted, that energy uses related to user behaviour and comfort requests account for about 72 % of the total energy use, confirming that occupant behaviour is one of the major drivers of the operational energy use (and the related services) in high performance buildings.
