Subtasks
Subtask A: Definitions & Large-Scale Implications
The objective of this Subtask (STA) is to establish an
internationally agreed understanding on NZEBs based on a common
methodology. The Participants shall achieve this objective by:
- The review and analysis of existing NZEB definitions and data
(site/source energy, emissions, exergy, costs, etc.) with respect to
the demand and the supply side;
- A study of grid interaction (power/heating/cooling) and time
dependent energy mismatch analysis.
- The development of a harmonized international definition
framework for the NZEB concept considering large-scale implications,
exergy and credits for grid interaction (power/heating/cooling).
- The development of a monitoring, verification and compliance
guide for checking the annual balance in practice (energy, emissions
and costs) harmonized with the definition.
Subtask B: Design Process Tools
The Subtask (STB) aims to identify and refine design approaches
and tools to support industry adoption of innovative demand/supply
technologies for NZEBS. The Participants shall achieve this
objective by:
- Documenting processes and tools currently being used to design
NZEBs and under development by participating countries.
- Assessing gaps, needs and problems and, considering the work of
STA and STC, inform simulation engine and detailed design tools
developers of priorities for NZEBs.
- The development/refinement of design processes and simplified
NZEB tools or interfaces (e.g. spreadsheet or web-based method),
linked to STC Solution Sets to support integration of NZEB
technologies and architecture at the early design stage.
Subtask C: Advanced Building Design, Technologies and
Engineering
The objectives of this Subtask (STC) are: to develop and test
innovative, whole building net-zero solution sets for cold,
moderate and hot climates with exemplary architecture and
technologies that would be the basis for demonstration projects
and international collaboration. The Participants shall
achieve these objectives by:
- Documenting and analyzing current NZEBs designs and
technologies, benchmarking with near NZEBs and other very low energy
buildings (new and existing), for cold, moderate and hot climates
considering sustainability, economy and future prospects using a
projects database, literature review and practitioner input
(workshops).
- Developing and assessing case studies and demonstration projects
in close cooperation with practitioners.
- Investigating advanced integrated design concepts and
technologies in support of the case studies, demonstration projects
and solution sets
- Developing NZEB solution sets and guidelines with respect to
building types and climate and to document design options in terms
of market application and CO2 implications.
Subtask
D: Dissemination
The objective of the dissemination activity is to support
knowledge transfer and market adoption of NZEBs on a
national and international level. This Subtask integrates
the activities of Subtasks A, B, and C. Each Subtask will be responsible
for the production of designated parts of the overall information
dissemination activity. Subtask leaders will be responsible for the
coordination of the individual contributions of Subtask participants and
for coordination with the other Subtasks where a combined output is
planned. Individual participants will be selected to take over
responsibility for each of the proposed dissemination activities. These
dissemination activities will be coordinated through the Subtask Leaders
Committee. The Participants shall achieve the objectives by:
- Establishing an NZEB web page, within the IEA SHC/ECBCS
Programmes framework, and a database that can be expanded and
updated with the latest projects and experiences.
- Producing a NZEB source book including example buildings for
investigated building types and climates.
- Transferring the Task outputs to national policy groups,
industry associations, utilities, academia and funding programmes.
- Establishing an education network, summer school and
contributions to the Solar Decathlon and similar student activities.
- Workshops, articles and features in magazines to stimulate
market adoption.
