Research of Biomass Micro-Cogeneration System Integration With a Solar Pv Panels in Zero-Energy Family Building

Abstract

Nowadays, any economic development is based on its sustainability. On the other hand, sustainability of the economy is no longer conceivable without efficient use of resources. Climate change and environmental degradation affects everybody and have no borders. It is essential, that all countries, regardless of their existing resources, are involved in environmental matters. The European Union (EU) has taken the initiative and has seen the possibility of transforming climate change into a guiding theme for sustainability and development in the economy. The EU has developed a green policy in order to transform all economic sectors into sustainable use of resources. EU is planning to achieve climate neutralisation in all sectors of the economy by year 2050. In order to achieve this objective, only the transformation of the industrial, transport and energy sectors will not be sufficient. The activity and willingness of each individual to achieve these objectives at their own household level will be crucial. It should change habits in all sectors important for households: food, transport, waste management and decreasing energy consumption in all mentioned sectors. Solar PV panels traditionally are used to reach zero balance, but taking in to account climatic conditions and seasonable solar irradiation activity, they can operate successfully during the summer and partly during the spring and autumn season. During the heating season, the efficiency of solar PV panel systems is very low. Use of innovative micro-cogeneration equipment producing both heat and electricity is more efficient during heating season in Latvia.In this paper case study of innovative biomass Stirling engine micro-cogeneration system integration with a solar PV panels in zero-energy family building will be present.

Environmental Impact Analysis of Residential Energy Solutions in Latvian Single-Family Houses: A Lifecycle Perspective

“…Single family residential house in Latvia with living area of 200 square metres is selected as the object of the study. It considered to be a typical house with annual heat consumption of approximately 39 MWh th and electricity consumption of 3516 kWh el based on [36]. The weather conditions in Latvia are described by the average annual air temperature of +5.9 • C with the warmest month is July of average temperature equal to 17.0 • C and the coldest months February with the average temperatures average minimum −7.9 • C. The sunny days when the sky is clear account for half of the possible sunshine-1790 h a year [37].…”

“…The quantitative values used for these datasets are based on estimations made in study [36] for an average single-family residential building in Latvia. Data from Ecoinvent are based on generalized data to global and country average with allocation at the point of substitution, meaning that burdens of by-products in unit process are attributed proportionally to specific processes generating these by-products.…”

CO2 emission mitigation of a hybrid photovoltaic and cogeneration system in computer hardware manufacturing industry: A case study in Thailand

“…In the moderate climate in EU countries, the PV system is most efficient during the summer while the cogeneration system is most useful during the colder winter months, when heat requirement is higher. Even though the cogeneration system is frequently unplugged throughout the summer, it functions as an effective compensator in cases of PV system outages, effectively bridging the electricity gap [7].…”
