An innovative technology that can be used to deliver renewable electricity production that is higher than the total electrical consumption of a building while covering the heat demand on a yearly basis is presented. The idea is to use a conventional ground source heat pump, slightly modified to revert its cycle and generate electricity, coupled with a horizontal ground heat exchanger and a solar thermal roof. This so-called reversible heat pump/organic Rankine cycle (HP/ORC) unit is a flexible system with three operating modes: Direct Heating, Heat Pump and Organic Rankine Cycle. This work focuses on describing the dynamic model of such a complex multi-component system (building, solar roof, ground heat exchanger, thermal energy storage and reversible HP/ORC unit) followed by techno-economic anaylsis of the system under different operational conditions. The study of influences includes: (building envelopes, climates, appliances, lightning profiles and heat demand profiles) . Finally, the profitalibity of this system is compared against a competitive mature technology for Positive Energy Building (PEB), including a heat pump and photovoltaic panels. The results show that in the Danish study case, single family house with a 120 m2 solar collector, the electrical production trough the ORC production yields 3012 kWh/year while the total annual electrical consumption is 2318 kWh/year. However, the economic feasibility study indicates that the HP/ORC systems is not competitive (592 € less in cash flow income) to the alternative, HP coupled with PV energy system solution. Nontheless, the HP/ORC unit becomes favourable in buildings where the heat demand is large.

If I am given a reasonable time-frame for completion, I'll get it done. I am also an author of many non-fiction books so I am not new to writing, rewriting, editing, and proofreading material. If I can be of value, please don't hesitate to select me. Thanks Faiza Gull

Hello! I am a native English speaker, and I have recently completed my Master's in English language and literature. I have three years of experience teaching academic writing at the university level, and three years of experience working as a freelance writer and editor. I will proofread your article, ensuring that there are no unclear elements, and that the final product is in perfectly clear academic English. Minor changes will be made using the "track changes" feature of MS Word, while any questions or recommendations I may have to clarify the content will be made using "comments," in order that I do not accidentally change the meaning of any of your text. I expect the whole project will take approximately 10 hours. If you have any questions, or if you would like to see a sample of my work, please do not hesitate to ask. I look forward to speaking with you soon =)

Hi, I am a native English speaker with a background in IT management and marketing. One of my skills is proofreading and copy editing. Luckily, I was born with the ability to immediately spot a type or grammatical error. Sometimes that is a nuisance when I only want to enjoy a book but it is perfect for your task. I do a lot of proofreading for large multinational corporations, many of whose employees are not native English speakers. This ensures that documents and letters to clients always contain perfect English. Your work will be completed in two parts. First, I track and highlight all my edits in Word. Then I accept all those changes into a new document and double check that one also, in case I have missed anything or perhaps introduced errors myself. You receive both documents. My speed is 2,500 words per hour and my rate is USD $29 per hour. Your task is 3 hours = $75 and I can complete it within 48 hours. Best wishes, Dan
