“…As compared to other previous studies [2,10,[24][25][26][27][28][29][30][31] the research carried out has studied the issue of projects for increasing the energy efficiency of the dwelling stock at regional and county level, showing that an optimal portfolio of projects at the regional level can be created by using LCC as a criterion for setting up this portfolio. LCC ro was determined in the research, corresponding to the optimal portfolio of projects at a regional level.…”

Abstract:The joint action of the European directives and the national strategies make the issue of energy efficiency of the dwelling stock one of the main research directions in the field. The purpose of this study is to create and apply a methodology for developing the portfolio of projects to increase the energy efficiency of the dwelling stock at a regional level through the use of life cycle cost. For this, eight types of energy efficiency improvement projects and three implementation scenarios were selected for the dwelling stock. For each project life cycle cost was determined in each county of the South-Muntenia region based on the estimation of the energy requirements, the costs of implementation and exploitation. In all three scenarios, the P3 Energy Efficiency Project (the reference building without shutters under the Romanian normative) had minimal life cycle cost in most counties in the region. For each scenario the life cycle cost was determined for the optimal portfolio of projects at regional level. The maximum scenario was chosen as the optimal scenario for regional implementation.

“…The paper investigates heat metering in the non-disconnected and the disconnected residence from DHS in a multistory residential building by using EnergyPlus software and relevant computer simulations. The software was already used for the research in multistory buildings (Chidiac et al 2011) for such investigations in similar moderate climates like in Serbia. The residence has a low heat demand compared to the average heat demand of all DHS consumers.…”

The paper presents investigations of space heating metering in a residence in a multistory residential building. The entire building is heated by a district heating system (DHS). The residence may be heated by DHS and/or electrical energy. The analyzed residence may be either the non-disconnected or disconnected from DHS. The residence has a low heat demand compared to the average heat demand of all DHS consumers. Space heating is simulated by using software EnergyPlus during the 6-month heating season with a weather file of Kragujevac, Serbia. Specially, it is analyzed how the district heating metering is influenced by inter unit heat flows from the neighbor residences. Then, the notion of heat stealing (theft) is explained. For the residence, the heat consumption coefficient inside the entire DHS is introduced to direct the special attention to the low heating efficiency of all heat consumers inside the studied DHS. In addition, the primary fuel consumption, CO2 emissions, and heat costs are calculated and discussed.

An economic feasibility optimization method for the life cycle cost (LCC) has been developed to apply energy saving techniques in the early design stages of a building. The method was developed using default data (e.g., operation schedules), energy consumption prediction equations and cost prediction equations utilizing design variables considered in the early design phase. With certain equations developed, an LCC model was constructed using the computational program MATLAB, to create an automated optimization process. To verify the results from the newly developed assessment tool, a case study on an office building was performed to outline the results of the designer's proposed model and the cost optimal model.
