Design Proposal

One-solving methods and techniques necessary to avoid inefficiencies and not economic costs as well as reduce the cost of housing construction is the method of Value Engineering. Value engineering is a method and cost control techniques to analyze a function to its value at the lowest cost alternative (most economical) without reducing the quality desired.At the writing of this study used a comparison method by comparing the initial design to the design proposal of the author. In the housing projects Upgrading Tirto Penataran Asri type 70, the application of Value Engineering conducted on the job a couple walls and roofs pair by replacing some work items with a more economical alternative but does not change the original function and high aesthetic level and still qualify safe. For that performed the step of determining a work item, the alternative stage, the analysis stage, and the stage of recommendations to get a Value Engineering application and cost savings against the wall a couple of work items and partner roof.The proposed design as compared to the initial design. Work items discussed was the work of a couple wall having analyzed obtained savings of Rp. 2,747,643.56 and the work of the roof pair obtained savings of Rp. 2,363,446.80. Thus the total overall savings gained is Rp 5,111,090.36 or savings of 0048%.

Energy communities have received considerable attention in the Global North, especially in Europe, due to their potential for achieving sustainable energy transitions. In Sub-Saharan Africa (SSA), energy communities have received less attention partly due to the nascent energy systems in many emerging SSA states. In this paper, we argue that these nascent energy systems offer an opportunity to co-create energy communities that can tackle the energy access challenges faced by most SSA countries. To understand how such energy communities are realised in the sub-region, we undertake a systematic review of research on energy communities in 46 SSA countries. Our findings show that only a few energy projects exhibit the conventional characteristics of energy communities; In most of these projects, local communities are inadequately resourced to institute and manage their own projects. We thus look to stakeholder engagement approaches to propose co-design as a strategy for strengthening energy communities in SSA. We further embed our co-design proposal in energy democracy thinking to argue that energy communities can be a pathway towards equity and energy justice in SSA. We conclude that energy communities can indeed contribute to improving energy access in Africa, but they need an enabling policy environment to foster their growth and sustainability.

Design Proposal

An economic and safety design proposal of the spatial grid structure is very difficult to find according to traditional design method.The group search optimization and its improved algorithm are applied in optimization design of a spatial grid structure in this paper. In this paper the finite element model of the spatial grid structure is firstly built through the platform of ANSYS. Then based on the parameterized programme language ADPL of ANSYS ,the group search optimization (GSO) and the quick group search optimization(QGSO ) are compiled ,the optimization analysis of the spatial grid structure are carried out. Finally, the optimization results and the optimization one from ANSYS are compared. It show that the optimization methods hereinbefore are feasible and the design proposals of them are better than the one of ANSYS.
