Integrated daylighting system based on smart controls for user satisfaction

Obiettivo



Objectives

The main objective of the project is to establish and verify a theoretical model for integrated lighting systems, accounting for human visual performance, visual comfort, usability, system level energy efficiency and environmental impact.

Other objectives are to study the possibilities of:
- use of adaptiveness to improve usability
- integration of PV elements into shading facade elements
- optimizing the lifetime of fluorescent tubes with respect to dimming and switching
- integration with Building Management Systems (BMS), Distribution Automation (DA) and Demand Side Management (DSM) to improve the efficiency of the whole building and to rationalize the use of energy supplied by the utilities.

Technical Approach

Currently the end-user needs of integrated energy saving lighting systems are being studied. Information is being collected via interviews at existing sites and tests in controlled conditions. Tests on the lifetime of fluorescent tubes under frequent switching or low level control are conducted. Information about integration to BMS, DA and DSM is collected.
Based on these tests a theoretical model will be formulated. This will be the basis for developing a family of products that can be used in existing and new buildings. Attention will be paid to the intelligence of the system, energy saving potential, overall cost effectiveness and environmental issues. An adaptive control system which is able to learn the preferences of each user will be realized. Fuzzy logic will be studied as a possible solution to achieve this goal. Intelligent system components, such as light sensors, will be developed. PV-elements will be integrated into sunblinds to optimize the use of daylighting. Luminaires will be adapted to fit the purposes of new daylighting systems.

Finally, the theoretical model and technology basis will be verified in controlled laboratory tests and pilot studies.

Expected Achievements and Exploitation

Practical methods for optimizing daylighting with artificial lighting will be published. These will include ways for predicting the gains from daylighting. Average annual energy savings of 50% compared to present practice and 20% compared to present state-of-the-art artificial lighting systems should be reached. This should give the system a payback time of less than 4 years with existing electricity prices.

A theoretical model and technologies for industrially viable products will be developed for daylighting control. The improved theoretical knowledge will be used in related European lighting standards. The project will help maintain the European leadership in energy efficient lighting technology and industry.
