A house in composite climate of Lahore (Pakistan) needs intensive cooling in summers; energy recovery ventilation to reduce humidity during monsoon and comfortable indoor temperature during winters. All these conditions have to be fulfilled with a reduced load on energy resources. Recent trends in construction and design of residential buildings in Pakistan symbolize uncontrolled use of energy resources. There is no data available with planning and developing authorities of housing sector that shows an account of energy loads of built houses. The potential of conservation of energy will be analyzed by actually studying the cooling and heating loads of recently constructed houses Key Words: Energy Conservation Potential, Module Study, Simulations

The objective of this research is to establish an appropriate operating strategy for a radiant floor heating system that additionally has an air source heat pump for providing convective air heating separately, leading to heating energy saving and thermal comfort in residential buildings. To determine the appropriate optimal operating ratio of each system taking charge of combined heating systems, the energy consumption of the entire system was drawn, and the adaptive floor surface temperature was reviewed based on international standards and literature on thermal comfort. For processing heating loads with radiant floor heating and air source heating systems, the heating capacity of radiant floor heating by 1 °C variation in floor temperature was calculated, and the remaining heating load was handled by the heating capacity of the convective air heating heat pump. Consequently, when the floor temperature was 25 °C, all heating loads were removed by radiant floor heating only. When handling all heating loads with the heat pump, 59.2% less energy was used compared with radiant floor heating only. Considering the local discomfort of the soles of the feet, the floor temperature is expected to be suitable at 22–23 °C, and 31.5–37.6% energy saving compared with those of radiant floor heating alone were confirmed.

Technical Guidance

Taking a typical rural building as an example, the paper compares various factors that affect the heat load of the building, studies related literature and the living habits of rural residents, and suggests that the calculated temperature of the heating room in rural residential buildings in cold areas in winter is 14~17?C. Analyze and compare the initial investment and the investment pay-back period after the thermal insulation measures are adopted for each envelope structure. With the dual goals of energy conservation and economy, it is recommended that rural households with different economic conditions adopt different thermal insulation measures to provide clean heating in rural areas in the cold north. Provide strong technical guidance for energy conservation and emission reduction.

The article discusses the features of the regulation of the housing and communal services market. It was noted that the housing sector is one of the key and plays a key role in human life. Utilities are highly dependent on a person’s well-being and health. The article presents an analysis of the growth in prices for utilities and housing, taking into account the available statistics. Also, in connection with the growth of paid services, including the cost of housing and communal services in the Sughd region of the Republic of Tajikistan, an analysis of wages and other economic indicators was carried out. In the article, the author explains the development of the industry with proposals for the reform of housing and communal services, the implementation of tariffs, the creation of management groups near residential buildings.
