Konstantinou, T. (author), Knaack, U. (author)Refurbishing the existing building stock is an acknowledged issue in the building industry. Even though awareness has been raised, the design phase of refurbishment projects is often problematic. The decisions taken in the early stages of the design determine the final result; however, the assessment of the environmental performance only happens...journal article

Konstantinou, T. (author), Knaack, U. (author)Given the very low renewal rate of the building stock, the efforts to reduce energy demand must focus on the existing residential buildings. Even though awareness has been raised, the effect on energy efficiency is often neglected during the design phase of refurbishment projects. This paper discusses an integrated approach to energy-efficiency...conference paper 2013

Henriksen, T.N. (author), Knaack, U. (author), Lo, S. (author)Glass Fibre Reinforced Concrete (GFRC) has been developed over the last 50 years into the material it is today. GFRC is mostly used as a cladding material and to a lesser extent for structural elements. This paper examines the challenges of using freeform thin-walled GFRC elements in the design and fabrication of a self-supporting artwork. The...conference paper 2015
