Abstract

This paper researches a potential method of incentivising AEC industry professionals to design to better than NZEB standards. Analysing the potential of a purposefully designed local microgrid storing excess energy generated by solar technologies embedded within the building envelope; the microgrid excess output is measured and recorded using a (Post Occupancy) “Blockchain” application and measured against the data provided at design stage on a (Predictive) “Blockchain” database. This paper researches how energy output predictions at design stage, by multidisciplinary teams, may be enhanced by BIM + Blockchain Technology. The paper researches the potential of a digital twin (predictive versus post occupancy) in pursuit of answering this question: “If a building can produce more energy than it is consuming, is there an opportunity for the building owner and/or design team/building occupants to sell the surplus energy as a commodity?” In turn, this creates the potential for “Added Value Networks”. The first being a financial incentive for designers to strive for the very best building performance, and the second, a financial incentive for building occupants to conserve energy leaving more energy for sale. This paper will test the predictive energy theory and report on data generated by virtual sensors in a BIM model recorded on a (Predictive) Blockchain. This will be the basis for comparing predictive energy use against actual energy output. Actual energy output during occupancy can be recorded using real time sensors matching the number and location of the digital sensors. The information on both databases are secured using the immutable and transparent properties of Blockchain. This can provide confidence for transactions, securing the “Added Value Network”.
