Solar energy, known for its abundance and sustainability, stands out as a preferred renewable energy source. Net-zero energy buildings (NZEBs) technology for an elementary school in Dayton, Ohio, was implemented using the f-chart, phi method, photovoltaic system, and the CombiSystem TRNSYS executable. The solar fraction achieved for the system was 56% utilizing the f-chart and phi method. The project required 181 collectors for heating and cooling loads and 578 photovoltaic collectors for electricity generation. Using the f-chart and phi method, the simple payback period was calculated to be 5 years. The optimal storage tank design was determined to be a 120-60 gallon configuration, achieving a solar fraction of 62.45%. The photovoltaic system generated energy valued at $191,135 annually, meeting the requirements for a net-zero energy building. This design provides clean energy without environmental pollution or CO₂ emissions. The total project cost amounted to $275,393.99, making it the most cost-effective design compared to alternative designs incorporating photovoltaic systems for cooling loads. 

Today’s organisations are under pressure to cut the ICT infrastructure energy costs and also use of ICT infrastructure resources in efficient manners. On other hand organisations ICT infrastructures are expanding rapidly and demands agility in ICT infrastructure solutions, business requirements and in technology change. Virtualization is the most effective way to reduce the energy cost while enhancing efficient utilization of resources and agility. To fulfill these demands organisations are migrating from physical infrastructures to the virtual infrastructures. Where organisations are migrating to virtual infrastructures to deliver the services to business there is also need to consider the right virtual infrastructure fundamentals for efficient service delivery. If the virtual infrastructure is unreliable or experience poor performance such issues are not only causing the problems for virtual infrastructure but also can damage the organisation reputation. This research is based upon Information Technology Infrastructure Library (ITIL), to find the key goals of capacity management and align the capacity management within virtual infrastructure to ensure virtual infrastructure is utilize in the most efficient, predictable and cost effective manner. This research will also investigate the how to apply capacity management best practices to improve performance, reduce operating cost, analyse current capacity, predict future capacity and make sure service level agreements are met

A business plan which is a formal writing and statement that describing new or existing business goals always helps organizations or investor to set the task that need to be performed in order to invest properly by potential investors to the entrepreneurs. It helps businesses who are seeking investment and convey their business visions to potential investors and customers. Further, it can be also used to attract employees and supplier in order to simply understand how the company in future can be managed efficiently. Simply a business plan covers all important set goals, mission, vision, and all the strategies that a company will use to meet them and if potential problem that may confront the business and the ways to handle them. The purpose of this research is to provide enough resources for business plan to develop a web store using e-commerce technology by using SellerDeck software solution and making a competing company where customer can easily purchase their favourite brand of mobile phones, tablet computers and its accessories. At the end of this research the results is that the ecommerce technology will increase all over the world because of making it easier for the enterprise business and customers for shopping information and view the contents of web store products and payment system.
