This paper describes the energy performance of a solar house over its first year of monitoring. The 2007 Solar Decathlon house currently sits on Santa Clara University’s campus at 60.4 m2. The house is powered entirely by solar PV and solar thermal off the grid. This solar energy house is heavily instrumented with more than 100 sensors to measure temperatures, humidity, power consumption of electric appliances, lighting, water, and performance of a 7.2 kW solar PV array and a sophisticated HVAC system. The instrumentation includes a full weather station. The house is divided into two interconnected modules, and constructed with high thermal insulation and sustainable materials. The instrumentation also allows quantifying energy performance of individual components as well as the overall energy performance of the house. The paper focuses on the complete energy balance of the house as a function of weather conditions, and of the performance of individual components. Of particular interest is the performance of the solar PV and solar thermal systems. The solar thermal system includes an absorption air conditioning unit, integrated with a thermal storage tank to provide all energy needs for water consumption and heating. The I-V curves of the full PV array are reported, demonstrating peak, off-peak, and seasonal performance and deviations from manufacturers’ conditions. Similarly, the overall COP of the solar-driven HVAC system is reported for both cooling and heating modes. Finally, it is shown how data can be used to demonstrate improvement of simulation tools for solar building energy performance. Although data has been collected since March 2009, this paper focuses on performance during summer 2009.

In order to utilize solar energy to meet the heating demands of a rural residential building during the winter in the northwestern region of China, a hybrid heating system combining solar energy and coal was built. Multiple experiments to monitor its performance were conducted during the winter in 2014 and 2015. In this paper, we analyze the efficiency of the energy utilization of the system and describe a prototype model to determine the thermal efficiency of the coal stove in use. Multiple linear regression was adopted to present the dual function of multiple factors on the daily heat-collecting capacity of the solar water heater; the heat-loss coefficient of the storage tank was detected as well. The prototype model shows that the average thermal efficiency of the stove is 38%, which means that the energy input for the building is divided between the coal and solar energy, 39.5% and 60.5% energy, respectively. Additionally, the allocation of the radiation of solar energy projecting into the collecting area of the solar water heater was obtained which showed 49% loss with optics and 23% with the dissipation of heat, with only 28% being utilized effectively.
