Approximating optimal building retrofit solutions for large-scale retrofit analysis

Towards Data-driven Building Retrofit

Due to the relatively low construction rate of new buildings in Europe, the energetic performance of the building stock can mainly be improved by retrofitting existing buildings. Current methods to derive and assess retrofit measures require either on-site inspection by an expert consultant and code based approaches, or numerical simulations using a building energy model that needs to be first ...

Employment Impacts of a Large-Scale Deep Building Energy Retrofit Programme in Hungary

Informed Building Retrofit based on Simulation and Data Analysis

With the availability of the many energy efficient technologies, significant reduction in energy consumption can be expected through retrofit of existing buildings. To achieve a cost-effective retrofit, however, a good understanding of the building system is necessary. In this study, two office buildings under retrofit in the Philadelphia area have been evaluated based on measured data and simu...

Integrated solar thermal façade system for building retrofit

In the perspective of the Net Zero Energy Buildings as specified in the EPBD 2010/31/EU, we propose the concept and design of a modular unglazed solar thermal (UST) façade component for facilitating the installation of active solar façades. The renovation of existing buildings offers an opportunity to improve the energy efficiency when using such a system and a novel design methodology tackled ...

Optimal retrofit design for improving process flexibility in nonlinear systems

In this paper the problem of establishing the optimal trade-off between investment cost for the retrofit and expected revenue that result from increasing flexibility in systems described by nonlinear models is addressed. A systematic procedure is first proposed for constructing the cost versus flexibility curve. A stochastic optimization method is then presented for evaluating the expected opti...
