“…Furthermore, another innovative way to save energy was developed by Shurui Yan [17] who used an already available energy source to heat houses in northern China. The author combined the cooking and heating system (space) presented in many rural houses and successfully could save energy by heating other rooms in the house by addressing energy from this source.…”

The study of energy sources has been an awareness of the modern world due to constraints on the current energy worldwide supply chain. The complexity of the theme as well as the consciousness of finite sources also the need of saving energy has become a priority. Although many papers have moved in this direction there is no record of papers studying the variables in a house heating system, which represents the highest energy consumption in many cold countries. This paper explores the energy-saving theme by studying the main variables present in houses’ heating systems in the winter season in cold countries like Canada, Russia, Norway, Iceland, Finland, etc. By using a novel combination of numerical thermal simulation by COMSOLTM and statistical analysis by MiniTabTM , it was possible to design an efficient thermal distribution in a house with the variables of the system by determining their significance and interaction qualitatively.

“…In Chartered Institution of Building Services Engineers (CIBSE) Guide [2], the empirical formula with independent variables solar radiation, outdoor air temperature, long-wave radiation heat exchange between the external surface of the envelope and the surrounding environment and outdoor wind speed, etc was proposed. In literature [3], the solair temperature model proposed by the former Soviet Union based on local climate characteristics is continued to be applied, which mainly distinguishes the long-wave radiation heat transfer between the surrounding environment and the external surface of the envelope, and between the sky and the external surface of the envelope. To simplify the implementation, a further simplified sol-air temperature model was proposed in Code for Thermal Design of Civil Building GB 50176-2016 [4] of China (Code 2016), which mainly considers solar radiation heat gain and air convection heat transfer, ignoring the role of the longwave radiation heat effect of the sky and surrounding environment.…”

The sol-air temperature is a hypothetical parameter to reflect the outdoor multi-field coupled thermal environments of air temperature, solar radiation, and long-wave radiation. The simplified model was proposed in code for thermal design of China which ignores the influence of long-wave radiation of sky and surrounding environment. However, the climate is characterized by strong radiation, high temperature and high humidity in tropical islands, and the underlying surface types are mostly sea surface. This may affect the applicability of sol-air temperature models. To explore the above issues, the Davis weather station and Kipp & Zonen solar radiation observation system were used to gather the meteorological and radiation data around the building, which is a case study building near the coastline in Sanya. Also, the dynamic temperature of the external surface of envelope and sea surface was captured. Then, the weather types were classified by clearness index, and the influence of sky and sea surface radiation on the sol-air temperature calculation of each orientation in different sky conditions is analysed. The results show that the sol-air temperature decreased by 1.07-2.44 ℃ on average considering the long-wave radiation of the sky and sea surface, especially in clear sky, with an average decrease of 1.49-3.85 ℃.
