In pursuit of the Net Zero Energy House: Lessons learned from architectural design in the Negev Desert.
Prof Evyatar Erell
As our understanding of the complex inter-relationships among the various factors that affect building energy consumption has evolved, it has become clear that solutions that at first appeared to be straightforward were later found to have confounding effects that became apparent only with hindsight. Technology may hold some of the answers to the dilemmas faced by architects seeking to reconcile energy efficiency with convenience and quality of life in the buildings they design, but a better understanding of what drives people's interaction with their environment holds the key to their successful resolution. This may help to explain why green, energy efficient buildings still comprise a minute fraction of buildings currently being built, in spite of the claims of the designers of such building concerning their benefits – to the occupants and to society – and of the generally favorable publicity such buildings have received in recent years. The talk will begin with an overview of the barriers to widespread adoption of energy saving architectural design, in general. The complexity of the issue will then be demonstrated by means of a detailed exploration of glazing and façade design in sunny locations.
Reasons for renovating old housing, energy-efficiency and feasibility: financial aspects of renovation projects
Prof. Seppo Junnila, Aalto University, Finland
The presentation will talk about the topic ”Reasons for renovating old housing, how to do it in an energy-efficient way, and especially how to finance it” from three different perspective.
Firstly the key business and societal drivers for renovating the old housing stock to be more energy efficient is introduced. The global climate change challenge and EU’s climate and energy package with 20-20-20 targets. Secondly the investors’ perspective to the issue with different investment calculation approaches the traditional life-cycle costing and more advanced green discounted cash flow analysis is discussed. Finally the presentation is concluded by introducing the actual market premium for low energy construction on the market.
