In the context of the increasingly severe energy crisis and global warming, green buildings and their energy-saving issues are being paid more attention in the world. Since envelope optimization can significantly reduce the energy consumption of green buildings, value engineering (VE) technology and building information modeling (BIM) technology are used to optimize the envelope of green buildings, which takes into account both energy saving and life cycle cost. The theoretical framework of optimization for green building envelope based on BIM-VE is proposed, including a BIM model for architecture, a life cycle cost analysis model, energy-saving analysis model, and a value analysis model. In the life-cycle cost model, a mathematical formula for the life-cycle cost is established, and BIM technology is used to generate a bill of quantity. In the energy-saving analysis model, a mathematical formula for energy saving is established, and BIM technology is used for the building energy simulation. In the scheme decision-making sub-model, VE technology integrating life cycle cost with energy saving is used to assess the envelope schemes and select the optimal one. A prefabricated project case is used to simulate and test the established methodology. The important results show that the 16 envelope schemes make the 16 corresponding designed buildings meet the green building evaluation standards, and the optimal envelope scheme is the “energy-saving and anti-theft door + exterior window 2+ floor 1+ exterior wall 1 + inner shear wall + inner partition wall 2 + planted roof” with the value 10.80 × 10−2 MW·h/ten thousand yuan. A significant finding is that the value generally rises with the increase of energy-saving rate while the life cycle cost is irregular with the increase of energy-saving rate. Compared with previous efforts in the literature, this study introduces VE technology into architectural design to further expand the current boundary of building energy-saving theory. The findings and suggestions will provide a valuable reference and guidance for the architectural design industry to optimize the envelope of green buildings from the perspective of both energy saving and life cycle cost.

The Cost

The current problem of ensuring energy saving and improving the energy efficiency of buildings and structures for agricultural purposes is identified. The geopolitical situation, import substitution programs and agricultural development programs set the task of developing domestic vegetable production, which in its turn requires the construction of new vegetable store buildings, as in most regions of Russia the harvest is collected once a year. In this regard, the current task is to ensure the energy conservation and achieve high energy efficiency of the vegetable store buildings. Energy saving is the basic technology for creating effective agriculture. The purpose of the study is to analyse the requirements for insulation materials for buildings and vegetable store facilities, taking into account energy efficiency and life cycle cost. The authors analysed the criteria for choosing a heater for the vegetable stores: low coefficient of thermal conductivity, water absorption, sorption humidity, frost resistance, biostability, lack of cold bridges, long service life. It is proposed to supplement the criteria for choosing a building insulation with the characteristics of the life cycle cost and the service life. Design and construction of agricultural buildings is proposed to be implemented using the concepts of BLC and BIM, the use of which gives an opportunity to design buildings with optimal energy efficiency parameters and take into account the cost of the life cycle. The cost of the buildings life cycle is the main of all the performance indicators when comparing alternative design options that differ by the application of advanced technologies and material resources and the contractors' offers when concluding contracts not only for purchase, but for servicing the subject of trades during its service life. The conclusions are made about the advantages of using foamed polyethylene foam for warming vegetable store buildings, as well as the conclusion about the expediency of adding criteria determining the sustainable development of the human environment, namely life cycle cost, service life, recycling ability. The formula for calculating the cost of the buildings life cycle, adapted to the specificity of buildings for agricultural purposes, is given.

The digital model of existing residential building is used to calculate the annual energy consumption, by simulation software—Autodesk Green Building Student. The horizontal solar panel systems offered by local market leaders were applied to calculate the annual savings, the required installation area, prices, etc. Consequently, the actual efficiency of energy saving technological process of residential buildings in Armenia is estimated. Based on the applied strategies and obtained fact, some recommendations are made for residential buildings.

Green Rating Certification is one of the important mechanism developed in last few decades worldwide to achieve sustainability in Built Environment life cycle. The early generations of Green Rated Built Environment from India have occupied for several years now. Therefore, it has become inevitable to assess whether these Built Environment are living up to expectations in their objective terms. Post Occupancy Evaluation is a process of systematic monitoring of Building's performance with predefined parameters and objectives after it is occupied for few years. Present research focuses on assessment of Green Rated Built Environment on the basis of performance parameters. Indoor Environmental Quality (IEQ) and Energy Efficiency are two performance parameters identified for current research. Seven Green Rated Institutional/office projects have been selected for Post Occupancy Evaluation. Indian Green Building Council (IGBC) has rated three projects and Green Rating for Integrated Habitat Assessment (GRIHA) has rated remaining four buildings. All seven projects are located in warm and humid climatic zone of India. Questionnaire Survey, on site measurement of Indoor Environmental Quality parameters and Energy consumption records are selected as a tool to measure performance of Green rated project.
