Open Data for a Change: A New Online Tool to Access Free Analysis of the Energy Savings Potential of Buildings
Given the reported lack of data on how buildings use energy and the impacts of building energy policy, policy makers and investors may feel like prisoners in Plato’s cave. How to make the right decisions chained in the dark with the perceptions that low energy buildings are unaffordable, that investing in energy efficiency renovation provides no return, that setting energy performance targets is bad for business, or that there is no way of meeting demand for urban housing while actually reducing total energy demand from buildings?
GBPN is moving forward in making building data transparent and publically available as well as engaging with various organizations into knowledge exchange.
In 2012 GBPN conducted a comprehensive study together with the Centre for Climate Change and Sustainable Energy Policy (3CSEP – Central European University) focused on the scenario analysis of building energy use and related CO2 emissions and mitigation potential of energy efficiency improvements.
Today, the GBPN launched a new Policy Tool for Renovation that compares best practice renovation policy packages. Learning from this comparative tool, I would like to present five graphs that illustrate some of the main outcomes of the project.
What level of ambition should we have in supporting policies that achieve CO2 emission reductions from buildings? What we can we do together that can harness Speed and Opportunity to go to Scale (S.O.S)?
The glass and steel office building at 10 Exchange Square sits in the middle of bustling downtown London, halfway between St. Paul’s Cathedral and the Tower of London. As part of the UK’s mandatory energy rating policy (a directive of the European Union), 10 Exchange Square was given a low grade of “E” on the alphabetical scale (A to G) for energy efficiency. The curious part is that in terms of actual consumption, 10 Exchange Square is 66 percent more efficient in use per square meter than a comparable B-rated office building. What gives?
It is well known that to be most effective policy strategies need to be organized into packages that optimize the combination of regulations, incentives and voluntary schemes. These three components are often referring to as ‘sticks’, ‘carrots’ and ‘tambourines’. However, our analysis of global best-practice building codes shows that the world’s best performance-based regulations are being designed to encourage and stimulate innovation rather than simply punish poor performance.
The GBPN launched a new interactive tool on building codes in late February. As part of this tool we assessed how well global best practice building codes perform with regard to achieving zero energy or positive energy in new buildings. A large group of experts were involved in the process of developing the 15 criteria and the results of these criteria as displayed in the tool as “city maps” or “windmills”.
At GBPN I’m participating in a collaborative project about existing buildings. The aim of the project is to investigate how we can scale up the best deep renovation projects across the world and show that buildings owners are doing and should be doing MORE AND DEEPER RENOVATIONS.
