Scheduling Method

Abstract From the perspective of global warming suppression and the depletion of energy resources, renewable energies, such as the solar collector (SC) and photovoltaic generation (PV), have been gaining attention in worldwide. Houses or buildings with PV and heat pumps (HPs) are recently being used in residential areas widely due to the time of use (TOU) electricity pricing scheme which is essentially inexpensive during middle-night and expensive during day-time. If fixed batteries and electric vehicles (EVs) can be introduced in the premises, the electricity cost would be even more reduced. While, if the occupants arbitrarily use these controllable loads respectively, power demand in residential buildings may fluctuate in the future. Thus, an optimal operation of controllable loads such as HPs, batteries and EV should be scheduled in the buildings in order to prevent power flow from fluctuating rapidly. This paper proposes an optimal scheduling method of controllable loads, and the purpose is not only the minimization of electricity cost for the consumers, but also suppression of fluctuation of power flow on the power supply side. Furthermore, a novel electricity pricing scheme is also suggested in this paper.

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.

Technical Details

Lightweight frame structures become increasingly popular in housing. They are used in single-, as well as multifamily, residential buildings. Such a tendency is in the line with sustainable development and the need for energy conservation. Lightweight frame partitions provide a certain comfort of life and remain environmentally friendly. However, they are tricky in terms of acoustics. Different factors and technical details influence their sound insulation. The paper presents the analysis of the acoustical effects resulting from different layers used on lightweight frame floors. Airborne, as well as impact sound insulation, have been considered, based on the results of laboratory measurements according to ISO 10140 standard.

Reduce Emissions

The building sector is crucial to reach the goals of common climate agreements. This paper contrasts three approaches to reduce emissions from typical residential buildings in Central Europe: the instalment of electric heat pumps (eHP), a thicker insulation of the thermal envelope and the encumbrance of a carbon tax. The use of less carbon intense fuels allows major savings of GHG emissions. An insulation thickness of 30 cm leads to GHG emission savings of 8% against a thickness of just 12 cm, while total cost savings (LCC) remain negligible. The introduction of a carbon tax of up to 250 €/t-CO2-eq. does not necessarily result in a reduction of GHG emissions due to increased costs of construction. It was further found that the focus of legal building regulations on heating demand is sufficient for now but needs to be revised as carbon intensities continue to decrease. The heating then reduces its share of the GHG emissions from 85 to 55% for typical residential buildings. The paper closes with a general expression of the lifecycle costs of a building which is dependent on the factors above.

Hot And Humid Climate

The use of Prismatic Skylights and its effects as a passive Energy Conservation Strategy in “Residential” and “Big Box Commercial Buildings” in hot and humid climate has been evaluated throughout this project. The potential benefits of using skylights reside in the fact that it reduces electrical lighting necessities but at the same time it contributes to an upsurge of the Cooling Loads of the conditioned space. Acknowledging the impact of skylights is fundamental to elaborate an optimized design of a building’s energy efficient mechanical system. To reach a sound conclusion, the evaluated buildings were modeled and their performance was simulated using the Department of Energy Simulation Program “Energy Plus”. To be able to compare the Energy Conservation Measure case (Using Skylights) with the Base Line (No Skylights), a photometric sensor was modeled to ensure that both cases sourced the same amount of light visible in the electromagnetic spectrum. Considering the Heating, Cooling and lighting energy consumption as variables, the variance between the ECM and the Base line for the residential case was 5% more energy consumption with skylights. For the Big Box Commercial Building there was a 5% deduction in energy consumption in the ECM case using 5% roof area covered with skylights. The results obtained from this investigation reveal a very promising effect in the implementation of skylights in “Big Box Commercial Buildings”, but not so optimistic in the case of “Residential Buildings” for hot and humid climate as shown by the simulation and monitoring data from the experimental case.
