The increasing prevalence of climate change impacts and rising energy prices has highlighted the need to achieve deep energy savings now. To accomplish this, stricter prescriptive performance requirements for residential buildings are needed. The intent of this work is to develop a framework and policy implementation strategy to achieve an 80% reduction in Ontario residential heating energy consumption by 2030. A tiered framework of consumption targets was developed using OBC 2012 SB-12 requirements as a baseline and sample compliance packages created for each tier. Construction costs for the baseline and each tier compliance package were estimated and simple payback periods determined. Impacts of fuel escalation rates on payback periods were also considered. Significant cost premiums were found between the baseline consumption and overall 80% heating energy reduction target. Lack of experience and perceived risk were found to be the greatest barriers to achieving the overall energy reduction target. A preliminary strategy and supporting policy tools was developed, taking into consideration the observed barriers to adoption.

Abstract Background Poor air quality and inadequate domestic heating sources are tightly connected problems in the Eastern-European countryside. There are a few alternatives to comprehensively solve these problems with an emphasis on economic and environmental sustainability. In this paper, individual heat pumps and energy efficiency measures are analyzed in four scenarios to investigate their role for cleaner and sufficient heating in rural settings. From a high-level perspective, this paper assesses the potential for electricity demand flexibility based on the use of individual heat pumps equipped with hot water storage. Methods In a first step, the current annual residential heating energy consumption of a rural area in Hungary is estimated with a bottom-up model using data from field surveys and official datasets. In a second step, four scenarios estimate the future heating energy consumption considering demographic trends and the average number of building retrofits (thermal insulation) performed yearly in the region. Results The reference scenario is a 20-year projection of heating energy consumption with modest retrofit actions which resulted in small energy savings. Alternative scenarios based on more effective retrofit actions reaching higher rates of the building stock would result in a 23–69% reduction in final energy consumption. Phasing out lignite from the heating energy mix would reduce particulate matter emissions. Each well-insulated dwelling with a heat pump-based system and hot water storage tank could provide theoretical flexibility of approximately 3.4 kWh per 24 h. Conclusions The current energy retrofit practices are not sufficient to solve the challenges faced in this area. Demand-side management policies based on the widespread use of individual heat pumps are an alternative to promote access to cleaner residential heating. An additional benefit is the potential for flexibility in electricity demand. Thus, this paper calls for an integration of energy retrofit with efficient heating (including hot water storage tank) to achieve results that further contribute to a future of sustainable energy.

Exhaust Gas Temperature

The gas boiler house is responsible for heating 308,000 m2 of residents in the community, and the historical heating energy consumption reached 3,000 tons of standard coal in 2012. The heating energy consumption index in this community is higher than that of heating energy consumption index in other residential communities. The heating system in this community is tested and analyzed comprehensively in this paper. The three aspects of heating system heat source, pipe network transmission and distribution and thermal user are combed and analyzed in this paper, to look for the energy-saving potential of each link. It is found that the exhaust gas temperature is 175℃ through the test of thermal efficiency of 2 # boiler in XX Community, and the heat loss of exhaust gas is higher. Meanwhile, it is found that the exhaust gas temperature is too high in all boilers through checking the operation record. It is found that the system water recharge is larger and the problems of leaking and aging thermal insulation layer and pipeline appear in the heating network through operation record analysis and on-site inspection. The analysis shows that there is a problem of hydraulic imbalance through the on-site test on the wall temperature of the supply pipe of the hot water supply wells in the residential buildings near, middle and far-ends. Analyze the problem existing in the heating system in XX Community, and put forward some corresponding energy saving technical proposals, such as flue gas condensing waste heat recovery, hydraulic balance adjustment and pipeline insulation improvement according to on-site survey and analysis; meanwhile, estimate the energy saving effect and the investment payback period.It is expected to realize the energy saving 728.72 tce and energy saving benefit of 1.4415 million yuan through three measures for energy saving and technicalm transformation. Estimated investment cost is 3.16 million yuan.

The paper presents results of heating energy consumption measurements in two pairs of buildings in community New Belgrade for two heating seasons. Influence of these measurements on energy savings is also presented. The measurements were carried out during heating seasons 2002/03 and 2003/04 in buildings in Block 34 and 63, connected to the district heating system "Beogradske elektrane". The buildings in each pair have similar architectural and thermal characteristics. One of the buildings in a pair was "test" building and the other "control" one. In the "test" building the energy consumption for heating of each apartment was measured, as well as total energy consumption for the whole building in the substation. Occupants were able to regulate the heating system. In the "control" building the energy consumption was measured only for the whole building, and occupants had almost no impact on heating energy consumption. The comparison of energy consumption for heating in the "test" and "control" buildings is given in the paper, as well as analysis of the influence of energy consumption measurements on the achieved energy savings. .
