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.

Green Building rating tools are the essential need of this era, to cope up with the sustainable development goals, climate change, and natural resource degradation through buildings. Realization of green building incentives decently increased within past few decades with abrupt declination in real estate markets and economic depletion has decelerated the interest of investors towards the green building projects. This research calculates influence of costing elements in MyCREST (IS-design) using questionnaire survey distributed amongst qualified professionals (QP’S) of green buildings and expert practitioners. Firstly, factor score and then weightage factor was performed to produce the final result with weightage output for evaluating weighatge and ranking of the relevant criteria of MyCREST and life cycle cost elements respectively. It is found that the criteria of storm water management has weighatge of 0.236 as highest and criteria environmental management plan (EMP) as 0.061 as lowest. Research also identified another perspective by finding association of cost element at design stage of MyCREST and found that management cost is highly associated at design stage with the value of 87.7%. The outcome of this research will add value to green building development and map road towards sustainable development using green building tools to uplift quality of life. Furthermore, this paves a way to integrate various stages of MyCREST with life cycle costing tool to potentially contribute in evaluating cost association through green building rating tool.

Sustainability has emerged as a critical concern in any viable physical planning and development. Hence, the Malaysian government has promoted the concept of green procurement also known as Government Green Procurement (GGP) that aims to minimize environmental degradation. In GGP, life cycle perspective thinking is introduced where life-cycle cost (LCC) tools act as decision-making in controlling the initial and future value of building ownership. Despite the increasing importance of green procurement and LCC in the planning phase of green projects, the viability and implementation of LCC is still lacking. Many have stated the benefits of LCC in green procurement for green building projects, however the criteria of LCC are not clearly determined. The study aims to determine the important level of LCC components relating to the green project planning phase. Questionnaire survey was distributed to 50 respondents composed of project team members that were involved in the selected green government projects. 32 respondents returned their responses to the survey. The results revealed that the highest rank of LCC components in green procurement is energy consumption cost, greenhouse gas (GHG) savings cost, acquisition cost, energy simulation cost and utilities cost. These results would elevate the use of LCC in the green procurement adoption and viability of green projects.

Green buildings have been gaining in popularity over the past few years in Jordan. This is attributed to environmental and financial reasons directly related to energy consumption and cost. Energy sector in Jordan faces two main challenges which are the fast growing of energy demand and the scarcity of resources to fulfill this demand. Green buildings can save energy by designing them as near Zero Energy Buildings, where they produce amount of energy almost equal the amount of energy they consume. In special cases green buildings can be designed as Net zero energy buildings, where they produce as much energy as they consume. Jordan government encourage people to adopt net zero green buildings by issuing the Renewable Energy and Energy Efficiency Law No. 13 of 2012, that allows selling excessive electricity to electricity companies. Despite these benefits of green buildings, they are not yet the norm in the building sector in Jordan. This can be attributed to the high construction cost of green building compared to traditional one. However, this may not be true if the whole life cycle cost of the building is considered, in which the cost not only include design and construction but also operation and maintenance as well. This paper aims to provide real life cycle cost analysis for a typical residential building in Jordan, and to search different effective building strategies and design scenarios that will lead to a successful near Zero Energy Building. The search will apply main green building strategies recommended for Jordan climatic zone. The outcome of this study is a list of best economically feasible design solutions and system selections that result in near Zero Energy Building in Jordan for residential buildings.

Based on the design status of green building in China, this paper delivers reflections on the green building about its the meanings, evaluation criteria and design requirements from three aspects: the cost, efficiency and hygiene. It also points out the importance of the concepts of “the intelligent integration of green" and "life cycle cost" in the design of green building as well as explores the design method of green building in Chinese traditional residences from the angle of low technology and hygienic city.
