To renovate or to demolish? – Some evidence on demolished buildings
Satu Huuhka; Tampere University of Technology; Finland
As European nations pursue to reduce their emissions, policies have a tendency to promote demolition over the other alternatives. Demolition is often justified with the existing buildings’ poor energy efficiency rating without taking into account a number other factors required to achieve real sustainability. In her presentation, Satu Huuhka discusses the choice between demolition and life cycle extension through renovation or adaptive reuse. She will also bring some examples of buildings demolished in Finland and discuss how much knowledge do we actually have in the field of renovation and adaptive reuse. The key questions of her lecture will be:
- Why do we demolish so much?
- Why should we choose life cycle extension over demolition?
- How much knowledge do we actually have in the field of renovation?
About the lecturer
Satu Huuhka (b. 1983) is an architect and a Doctor of Science in Architecture. She currently holds the position of a postdoctoral researcher in Tampere University of Technology, Finland, where she has worked since 2009. She is the principal investigator in the research group ‘Built Environment in Transition’, focusing on the building stock as a reserve for future needs. She has authored several peer-reviewed scientific articles on such topics as vacancy, renovation, demolition/deconstruction and reuse/recycling. She also teaches architectural renovation for both Finnish and international students at bachelor and master levels.
Deep integrated renovation – the Estonian KredEx renovation grant programme for apartment buildings
Jarek Kurnitski; Tallinn University of Technology
The first KredEx renovation grant programme in 2010-2014 assisted in the renovation of around 700 apartment buildings in Estonia. After evaluating the results of a comprehensive survey carried out in the newly renovated buildings that had recieved the grant, KredEx made a few alterations to the application requirements, mainly revolving around more strict and detailed standards for ventilation systems. They also increased the maximum grant from 35% to 40% of the total cost of the renovation project. During the period of 2015-2020 KredEx has planned to invest about 102 million euros into renovation projects which would mean a significant contribution to the Estonian economy. In his presentation, Jarek Kurnitski discusses the KredEx grant programme and the consequent effects on the Estonian economy. His lecture will cover the following topics:
- What is the KredEx renovation grant programme?
- What are the requirements to be eligible for a grant?
- How can we fulfil those requirements?
- What effects does this grant programme have on the Estonian economy?
About the lecturer
Jarek Kurnitski is a professor at Tallinn University of Technology and Aalto University, and a vice-president of a European professional organization REHVA, Federation of European Heating and Air-Conditioning Associations. In TUT he is the leader of Estonian Center of Excellence in Research ZEBE, Zero energy and resource efficient smart buildings, and the leader of the Nearly Zero Energy Buildings nZEB research group which today operates at both universities. As one of leading scientists in energy performance and indoor climate research he has been know from the preparation of technical definitions for nearly zero energy buildings in European level as well as from development of present energy calculation frames of Estonian and Finnish energy performance regulations.
