APPENDIX A3: RESEARCH PROJECT ECCO-BUILD
The objective of the project ECCO-BUILD is to develop a new generation of control
devices for solar shading systems, glare control systems, electric lighting and HVAC
systems for the simultaneous optimisation of building energy consumption and comfort.
Another important goal of the project is the development of glare criteria for windows
and daylighting systems, which can be used for control purposes, and the development of
a new device for luminance measurements.
The project is split into 7 work packages:
User assessment: Develop new criteria for glare rating to be used as input for
building management systems. The basis for the criteria are user acceptance studies
in different countries.
Measurement facility: Design and construct a device for luminance
measurements.Characterise different facade systems.
Control device: Develop new control algorithms and construct a prototype
Design tool: Develop an information package for building planners and scientific
software tools to predict the energy impact of different control strategies for glare
protection and solar shading devices.
Pilot buildings: Test the algorithms developed in WP4 in an occupied multiroom
building and other pilot buildings.
Dissemination: Disseminate results to scientists, standardisation bodies, component
and facade manufacturers, architects and building planners and set up a project
Duration, partners and funding of the project: The project has been started in November
2002. Its planned duration is 3 years, i.e. until October 2005. The partners are:
Fraunhofer Institute for Solar Energy Systems (D, coordinator), Danish Building and
Urban Research (DK), Ingélux S.a.r.l.(F), LESO-PB/Swiss Federal Institute of
Technology, Lausanne (CH), Hüppe Form (D), TechnoTeam (D), Bug-AluTechnic AG
(A), and Servodan S/A (DK).
Work in progress and main results already achieved: The work packages 2 and 4 have
been allocated the most significant part of the work. For WP 2 (main contributors DBUR
and ISE), some preliminary results show that the illuminance in the vertical place
oriented in the same direction as the view of the user might represent a good index for
visual comfort, together with the usual horizontal workplane illuminance. For the WP 4
(main contributors are LESO-PB/EPFL and ISE), an exploration work has been done,
considering an original control algorithm for venetian blinds using a Bayesian algorithm,
and different variants for the solar shading transmission function. For the WP 6 (main
contributors are also LESO-PB/EPFL and ISE), only the preparation work has been done,
but no measurement is yet available.
