Control Strategies for the 4th Floor and Details of FBS Hub

Project Introduction

1.1 General Information of UAL: Project

The London College of Fashion is part of the University of the Arts London. It is specialised in fashion education, research and consultancy. Moving to a new single campus on the Queen Elizabeth Olympic Park, UAL is part of a new development for London known as East Bank. East Bank will be a new powerhouse for innovation, creativity and learning. The new building is being designed by architects Allies and Morrison.

It will be day-lit and naturally ventilated, with factory-like steel-framed windows, internal atria for flexible learning, and lots of green spaces. As lighting designers, we took care of designing a tailor-made control strategy for the building, the customer and the users. Both well-adapted daylight harvest system and well-designed artificial lighting will work together to let this building standing out in East Bank area.

In this reports, lighting control design will be carring out for the 4th Floor of this building with detailed design of FBS Hub, from Stage 2 Concept to Stage 4 Technical Design a described in the RIBA Plan of Work 2020.

1.2 Design Perspectives based on User Experience

COMFORT AND WELLBEING

Our aim is to ensure visual comfort through the use of a control strategy designed for the building. The control strategy plays a fundamental role in obtaining a strong technical and stylistic content, always ensuring maximum visibility and making the space bright and appealing.

VISUAL EFFECT

The intent of our project is the combination of functionality and sensoriality. We want to give lighting an added value, transforming it into a non-static tool: a device capable of interacting dynamically with the environment and the users.

SUSTAINABILITY

Appropriate lighting control is an essential part of any lighting system and it plays a fundamental role in the reduction of energy consumption together with mindful use of renewable resources and attentive recycling practices.

USER INTERFACE

User interfaces enable communication to and from devices. At the heart of our lighting control strategy there is the search for a lighting system tailored to the needs of space users.

CLIENT NEEDS

The lighting control system of the building is designed based on the clients energy reduction objective and on the cost of installation and maintenance. Flexibility is the key word to support the user’s visual needs and create a desired mood or ambience.

2.1 Overall control strategy

Lighting control strategies, such as real occupancy control, daylight linking strategy, time switch, tuning and dimming, can be combined to save energy in specific areas of a building. The goal for this project the lighting control system for the forth floor of LCF building is to reduce energy consumption while providing adequate light for the tasks. The lighting control strategy are built minding the different lighting needs that correspond to different areas in the building. In this context we have classified each room according to its occupancy and the way it is used. Together with the space analysis we are considering the different users lighting needs and control expectations.

2.2 Occupancy analysis and Design Criteria

*based on BS EN 12464-1:2011 (2012), BRE DG 498 (Garston: BRE), SLL (2011) Lighting for education SLL Lighting Guide 05, SLL (2016) Control of electric lighting SLL Lighting Guide 14, SLL (2018) The SLL Lighting Handbook

2.3.1 Daylight analysis

2.3.2 Daylight Photocell arragement

The simulation of daylight anaylsis were conducted by a simplified mpdel of UAL buildings. With general factor of all surface,t the general daylight factor is above 2.2% and the DA can reach 68%. These results shown in the diagram proves this building can harvest fairly enough dalight while working houes, which means daylight should be carefully used in the forth floor.

2.3.3 Annual Sunlight Hour Analysis

Combined with the daylight autonomy and daylight factor for these rooms, we know that this floor is potentially using daylight. A daylight control area of 8m was determined. Using auto-dimming, it can save up to 15% energy when areas are brighter than required.

Annual sunligh hour analysis were conducted by accurated model. The south facade part of both floor 4 and the FBS Hub and received large amount of dayllight.

3.1 Lighting Design and Light Control Design Layout

Zone of heart

The central heart of the building and the rest of the rooms that form the exterior façades in lighting deisgn and control design were operated separately. This area of the 4th floor is characterized by the presence of transition areas, such as stairs, elevators and corridors, and by open and airy areas, designed and accessible to all students.

The transition areas are characterized by presence detectors that act, in the corridors by modulating the intensity of thelight and in the stairs, by turning on and off the LED stripes that light the contrast between the steps. The three central rooms are open in order to take advantage of the light coming from the skylights.

Zone of Shell

The rooms surrounding the inner heart of the building constitute the external façades. These are characterized by a diff erent need in user’s interface and therefore a distinct control strategy. In order to take advantage of daylight, we have decided to use a system of daylight linking in every room where the windows’ surface covers more than 20% of the total surface. As regards the appearance of light, we want these areas to have a different CCT, colder compared to central areas. Furthermore, the choice of luminaires has been directed towards appliances designed for school or work environments, which are not disabling.

Level4 - Proposed Control Protocal 04

4.1 DALI Control Protocal Intergrated with BMS

DALI is stands for Digital Addressable Lighting Interface. It is a lighting interface system that allows lighting to use a digital signal for more precise and flexible control. Using a two-way method, the system enables the user to communicate with LED drivers and ballasts, and vice versa, via a DALI controller, which is typically a computer system with software or dimming controller. DALI is also an international standard ( IEC 62386), created to ensure compatibility and interchangeability across lighting systems in the industry. In this building and also the forth floor or FBS, DALI system are working together with Building Control System to correspond the environment and time, also to create scenes among all needed areas in the building.

4.1.1 DALI System Diagram 4.1.2 System of UAL 4th Floor

4.2 DMX-DALI Conversion

With increasing crossover between the entertainment, architectural and commercial lighting sectors, environments that require integration between DMX and DALI equipment are becoming more common. To convert DMX into DALI in this building of facade lighting for the exterior wall washing light, DMX to DALI is required. DMX to DALI quad converts packets from a DMX controller to DALI commands, enabling control of up to four circuits of 64 DALI ballasts each. This will achieve that DALI discovery to identify devices on the network, and enables ballasts to be controlled with the usual Broadcast, Channel, Group and Scene commands.

4.3 PWM-DALI Conversion

In the FBS Hub, the RGB linear ceiling recessed light need convert from PWN to DALI system, which can extracts dimming levels and address information from the incoming DALI data to control each of these four PWM dimming outputs individually.

PIR sensor

The Multisensor is a compact unit that combines a light sensor for constant light control and a passive infrared (PIR) presence detector to provide energy-saving functions in a DALI system.

The light sensor measures reflected light from the surface directly beneath it. The unit uses this information to maintain a constant light level by adjusting the lamp outputs.

The PIR sensor enables the Multisensor to switch the lights on when its coverage area is occupied, and off when it is unoccupied.

Light sensor Status LED

The sensor’s settings are adjusted using Helvar’s Designer or Toolbox software.

The High Bay Multisensor is compatible with Helvar’s lighting systems and configuration software, Designer and Toolbox.

Key Features

Due to its excellent detection performance, the Multisensor is especially suitable for applications where small or slow movements take place for extended periods of time, such as offices or classrooms. Since its detection sensitivity is less dependent on movement direction than that of most PIR sensors, fewer units are required to reliably cover a target area.
