Abstract
Given the global climate crises, the enormous construction activity and the rising demand for comfortable living spaces around the world, it is not only the task for today to explore the feasibility of zero-energy buildings based on advanced technology concepts, but also the task for a zero-carbon future to transform the entire building stock. This chapter explores an integrated road-mapping approach to guide the various relevant levels of global, regional and national governance, on sector level as well as on the level of individual buildings. It will explore how key technologies, individual building configurations, infrastructure and the governance framework can be strategically developed in specific market contexts to achieve ambitious performance goals in the given time frame. It also introduces the concept of individual building renovation roadmaps and design features to be prepared in new and existing buildings to enable the retrofit of key technologies when they become economically and technically feasible in the given market. The roadmap approach with a clear performance target and a mid- and long-term vision is paramount since market conditions do not exist yet to implement such buildings in all market situations today. The text presents the concept of transformation roadmaps on the various levels of implementation and introduces examples.
Highlights
We do know today how to design and how to build near-zero-emission buildings
Even plus-energy building performance can be achieved [1] by the integration of highly energy-efficient building design, advanced energy systems and solar energy applications
In case a roadmap approach is applied as part of a governance framework or for performance assessment in a subsidy scheme, these predictions can be defined by the operating body to support the designers and assessors of the individual building projects
Summary
A technology roadmap is an instrument to outline the expected future development and the boundary conditions of such development. A technology roadmap will document the current context and will draft the desired future performance. It will develop a pathway from the current situation towards the intended future performance. Besides the graphical representation, table structures and narratives are used in the development and communication of roadmaps. As instruments for planning for the future and for directing the development towards the desired state, roadmaps have been used on various levels in management, economy and policy contexts. Roadmaps are used for product planning, the development of capabilities and strategic knowledge assets and to align activities between departments towards a coordinated goal. Focuses on the implementation of strategy, to support the management of integrated R&D programmes This type is more closely related to project planning methods (Gantt charts). A retrofit plan for a low-emission building is to be promoted with layers along with the main components of the energy balance and the elements of the energy concept
