- PublikationNet zero enrgy balance for high-rise buildings(Advanced Building Skins, 2016) Hall, Monika; Geissler, Achim [in: Advanced Building Skins]Multifamily dwellings and office buildings with a square and a stretched footprint with up to 40 floors are considered for a net zero energy balance. A wide range of parameters is investigated in regard to their impact on the zero energy balance. The main results gained by the simulation based research described above can be summarized as follows: Only the HVAC zero balance can be achieved for up to 40 floors for all variants studied but one. The five main parameters in regard to achieving a HVAC or TE zero energy balance are, efficient electric devices and lighting, low heat demand, the type of heating system, the actually available area for PV and the overall efficiency of the PV-System. The results show that a net zero energy balance for HVAC only or for total energy can be achieved for large multifamily dwellings and office buildings of up to 40 floors. To this end, however, apart from a well-insulated building envelope, electronic devices, lighting and PV systems with a very high efficiency are necessary. With further improvements in the efficiency of devices, lighting and PV-systems, reaching the "zero" will become easier.04 - Beitrag Sammelband oder Konferenzschrift
- PublikationTwo Years of Experience with a Net Zero Energy Balance - Analysis of the Swiss MINERGIE-A Standard(Elsevier, 09/2013) Burger, Bastian; Hall, Monika; Geissler, Achim [in: Energy Procedia]With the net zero energy balance for heating, domestic hot water, ventilation and auxiliary energy, the Swiss MINERGIE-A Standard is a major step towards standardized, economically feasible net zero energy buildings. Not only the zero energy balance but also the requirement for limited embodied energy is a new challenge for architects and designers. In the two years since the launching of the Standard and the writing of this paper, approx. 240 buildings have been certified or pre certified. The new standard is widely accepted and its challenges are appreciated in the building sector. A cross analysis shows that a wide range of different energy concepts and embodied energy strategies are possible in the scope of the Standard. The wide variety of options is one of the main findings of the rollout of this new zero-balanced standard.01A - Beitrag in wissenschaftlicher Zeitschrift
- PublikationOne Year Minergie-A—Switzerlands Big Step towards Net ZEB(David Publishing Company, 01/2013) Hall, Monika [in: Journal of Civil Engineering and Architecture]The first available label standardizing a zero-balanced type of building is the Swiss Standard Minergie-A. The Standard prescribes an annual net zero primary energy balance for heating, domestic hot water and ventilation. Electricity consumption for appliances and lighting is excluded. Additionally, Minergie-A is the first standard worldwide which includes a requirement in regard to embodied energy. Based on an analysis of 39 Minergie-A buildings, this paper shows that a wide range of different energy concepts and embodied energy strategies are possible in the scope of the label. The basis of all Minergie-A buildings is a well-insulated building envelope. However, the step from the Swiss Standard Minergie-A to a Net ZEB (net zero energy building) standard which includes electricity consumption for appliances and lighting is not a very big one. Increasing the size of the photovoltaic system is sufficient in most cases. Anyway, some of the Minergie-A buildings evaluated are also Net ZEBs. In this paper, it is also shown that the net zero balance during the operational phase of Net ZEBs clearly outweighs the increased embodied energy for additional materials in a life cycle energy analysis.01A - Beitrag in wissenschaftlicher Zeitschrift
