The use of solar energy at the building scale today presents two viable options: grid-tied photovoltaic systems, and thermal systems utilizing absorption or adsorption cycles for cooling. The economic viability of either option is presently commensurate, however, specifically for the case of thermal systems, there is a major caveat, namely that the system must truly save energy, and must be reliable over its typical expected lifetime. While the basic design of a solar thermal system is relatively simple, there are many details that, if not carefully considered, can lead to poor performance, lack of reliability, and potentially catastrophic failure. Based on experience in designing, building, operating and analyzing such a system for several years, a set of guidelines is presented for each major system component, namely the solar loop, hot storage, cold storage, the heating and cooling subsystems, and the control system. These design recommendations should assist engineers in preventing costly mistakes that are difficult to correct. If followed, the guidelines should also reduce maintenance and prolong trouble-free performance of building-scale thermal systems. Keywords: robust design, reliability, economic performance, energy efficiency. BackgroundBuilding operation comprises a substantial fraction (40-50%) of the overall energy budgets of industrially developed countries [1] and an even larger fraction of the electric energy budgets (>70%). The advantages of minimizing the related energy expenditures are obvious, and have studied extensively in the last several decades, especially since the first and subsequent energy crises raised awareness Energy and Sustainability III 3

Abstract:To cope with 'Post-2020', each country set its national greenhouse gas (GHG) emissions reduction target (e.g., South Korea: 37%) below its business-as-usual level by 2030. Toward this end, it is necessary to implement the net-zero energy building (nZEB) in the building sector, which accounts for more than 25% of the national GHG emissions and has a great potential to reduce GHG emissions. In this context, this study conducted a state-of-the-art review of nZEB implementation strategies in terms of passive strategies (i.e., passive sustainable design and energy-saving technique) and active strategies (i.e., renewable energy (RE) and back-up system for RE). Additionally, this study proposed the following advanced strategies for nZEB implementation according to a building's life cycle: (i) integration and optimization of the passive and active strategies in the early phase of a building's life cycle; (ii) real-time monitoring of the energy performance during the usage phase of a building's life cycle. It is expected that this study can help researchers, practitioners, and policymakers understand the overall implementation strategies for realizing nZEB.

The world is shifting toward cleaner and more sustainable power generation to face the challenges of climate change. Renewable energy sources such as solar, wind, hydraulic are now the go-to technologies for the new power generation system. However, these sources are highly intermittent and introduce uncertainty to the power grid which affects its frequency and voltage and could jeopardize its stable operations. The integration of micro-scale concentrated solar power (MicroCSP) and thermal energy storage with the heating, ventilation, and air conditioning (HVAC) system gives the building greater leeway to control its loads which can allow it to support the power grid by providing demand response (DR) services. Indeed, the optimal control of the power flowing between the MicroCSP, the HVAC system, and the thermal zones can bring additional degrees of freedom to the building which can be relegated to the power grid based on the objective function and the incentives provided by the latter. This article presents an in-depth investigation of the MicroCSP potential to provide ancillary services to the power grid. It focuses on evaluating the effect of incentives provided by the power grid on the building participation to the load following programs. It also demonstrates how the MicroCSP can help the building deal with constraints related to load peak shaving and ramp-rate reduction set by the power grid as part of long-term DR contracts. A sensitivity analysis is carried out to confront the results to prediction uncertainties of the energy prices and the weather conditions.
