UCL (University College London) Libraries Masterplan: Masterplanning Report

BDP were appointed to undertake a Masterplan for the UCL Main Library and the UCL Science Library and to identify how these buildings could be re-ordered to significantly improve the quality of the library environment and to facilitate the delivery of library services. An initial brief was agreed with UCL’s Estates Management Committee and a Masterplan Steering Group established including academic representatives, library staff and design consultants. To inform the development of this brief, UCL Library Services undertook a number of consultation exercises with users of the Library; students, academic staff and external users, together with Library staff. A number of visits to exemplar library buildings in the UK and continental Europe were also undertaken to inform the development of options for the buildings. Following the development and review of initial options for both the Main Library and Science Library, it was agreed a further, hypothetical New Build Central Library Option should be reviewed, to accommodate a relocated and consolidated library service encompassing 7 of the 16 existing libraries currently distributed across the UCL Estate

Building envelope design as a contribution for improvement of urban spaces and social housing environmental quality

The design of building envelope and the definition of its elements, can influence both the quality of the external spaces perception and the living standard referred to internal building spaces. This improvement depends by the planning of some component design. Particularly, solar shadings and integrated plant solutions, also thanks to an increasing consequential interest about the issue and the legislative and normative evolution, represent factors able to be involved both in the performance and morphological quality of building envelope (improvement of energy efficiency and living quality of internal spaces), which can influence the perception of environment. A study about this questions has been conducted through the elaboration of a system of Best Pratices, a Code of Practice, for the new Plans of Zone of Rome Municipality. The indications contained in the Code takes in examination the integration-mitigation and facilities connection of solar collectors in the building design, and the possibility of integration between solar shading and collector elements, customized like a support tool for the sustainable design of building envelope. The design of building envelope, reported to morphological and technological issues, can assume particular importance in the definition of living quality. Design of closures, developed through some indications referred to its technological components, can influence both the quality perception of external living spaces through the morphological definition of building, and the life quality of internal spaces by the implementation of energy efficiency of building system. Solar shading in particular, also thanks to the increasing consequential interest in the evolution of legislation about the argument, more in the future will represent a fundamental element for design and the increment of performance and morphological quality of building enclosure

Building institutional capability in e-learning design

We detail the research, development and initial outcomes of an intervention process to promote capability building in designing for e‐learning at a dual mode university in the UK. The process, called CARPE DIEM, was built on a pilot study and became a Higher Education Academy ‘Pathfinder’ project named ADELIE. We report on the model workshop, its deployment, research and development over a 12‐month period with a variety of subject groups working in small teams with learning technologists, pedagogical facilitators and librarians. Outcomes include improved scores on an institutional e‐learning benchmarking exercise and increased capability for designing for online activities for students in the Virtual Learning Environment (VLE). The model is stable enough to be tried in other institutions and continues to develop in scope

Sustainable design for building envelope in hot ‎climates; a case study for the role of the dome as ‎a component of the roof in heat exchange

Architectural design is influenced by the actual thermal behaviour of building components, and this in turn depends not only on their steady and periodic thermal characteristics, but also on exposure effects, orientation, surface colour, and climatic fluctuations at the given location. Design data and environmental parameters should be produced in an accurate way for specified locations, so that ‎architects and engineers can confidently apply them in their design calculations that enable precise evaluation of ‎the influence of various parameters relating to each component of the envelope, which indicates overall thermal ‎performance of building. ‎The present paper will be carried out with an objective of thermal behaviour assessment and characteristics of the opaque and transparent parts of one of the very unique components used as a symbolic distinguished element of building envelope, its thermal behaviour under the impact of solar temperatures, and its role in heat exchange related to a specific U-value of specified construction materials alternatives. The research method will consider the specified Hot-Dry weather and new mosque in Baghdad, Iraq as a case study. Also, data will be presented in light of the criteria of indoor thermal comfort in terms of design parameters and thermal assessment for a“model dome”. Design alternatives and considerations of energy conservation, will be discussed as well using comparative computer simulations. Findings will be incorporated to outline the conclusions clarifying the important role of the dome in heat exchange of the whole building envelope for approaching an indoor thermal comfort level and further research in the future

Building the Evryscope: Hardware Design and Performance

The Evryscope is a telescope array designed to open a new parameter space in optical astronomy, detecting short timescale events across extremely large sky areas simultaneously. The system consists of a 780 MPix 22-camera array with an 8150 sq. deg. field of view, 13" per pixel sampling, and the ability to detect objects down to Mg=16 in each 2 minute dark-sky exposure. The Evryscope, covering 18,400 sq.deg. with hours of high-cadence exposure time each night, is designed to find the rare events that require all-sky monitoring, including transiting exoplanets around exotic stars like white dwarfs and hot subdwarfs, stellar activity of all types within our galaxy, nearby supernovae, and other transient events such as gamma ray bursts and gravitational-wave electromagnetic counterparts. The system averages 5000 images per night with ~300,000 sources per image, and to date has taken over 3.0M images, totaling 250TB of raw data. The resulting light curve database has light curves for 9.3M targets, averaging 32,600 epochs per target through 2018. This paper summarizes the hardware and performance of the Evryscope, including the lessons learned during telescope design, electronics design, a procedure for the precision polar alignment of mounts for Evryscope-like systems, robotic control and operations, and safety and performance-optimization systems. We measure the on-sky performance of the Evryscope, discuss its data-analysis pipelines, and present some example variable star and eclipsing binary discoveries from the telescope. We also discuss new discoveries of very rare objects including 2 hot subdwarf eclipsing binaries with late M-dwarf secondaries (HW Vir systems), 2 white dwarf / hot subdwarf short-period binaries, and 4 hot subdwarf reflection binaries. We conclude with the status of our transit surveys, M-dwarf flare survey, and transient detection.Comment: 24 pages, 24 figures, accepted PAS

Digital wood craft

In 1995, Robin Evans points out in his book The Projective Cast how the development of techniques changed architecture and the space inhabited in times of Gothic and early Renaissance. We see a parallel phenomenon today, where the interplay of technology and tool gives shape to new design (Kolarevic 2005). Yet in opposition to the interwoven fields of design and craft of the late Gothic, todayis building sector is enormously diversified, and a growing complexity in the building process and number of used materials can be observed. This gives an opposite point of departure into a more integrated field of design and innovation in architectural design and building industry

A life cycle assessment (LCA) of a low energy / passive house in northern Sweden, including building materials and energy use is reported. The case study building is semi detached house for two families situated in Östersund (lat. 63°N), Sweden. Each apartment having a floor space of 160 m2 divided on two floors. The building was constructed during 2010 with a design meeting the requirements for Swedish passive houses as defined by the Forum for energy efficiency buildings (FEBY) and the Swedish center for zero energy houses (SCNH).When it comes to more sustainable buildings, energy use in the build environment has been in focus for some time. The life cycle assessment in this study reveals that the building materials can contribute significantly to environmental burdens of a residential building in northern Sweden. Energy efficiency, efficient use of good building materials and issues of appropriate design need to be discussed in the same context to move toward a more sustainable built environment.For energy efficient buildings in a energy system with renewably based energy carriers, building materials might give rise to a significant or even dominating part of the life cycle impact of a building. This give rise to considerations regarding choices of building materials as well as design of buildings to minimize such impact; while not forgetting social aspects impacted by building design

Design Margins: Impact on Building Energy Performance

This paper examines the addition of design margins for building services energy infrastructure during the design process. It argues that care must be taken when applying margins; ensuring cumulative effects do not undermine the ability of systems to be energy efficient. An example of a hospital Trust is provided showing the addition of design margins impacting the energy efficiency of services provided. Tensions are found between delivery of flexibility, adaptability and other change parameters and the need for the system to be bounded, so as to encourage effectiveness

Simulation and BIM in building design, commissioning and operation: a comparison with the microelectronics industry

Analogy between the Microelectronics and Building industries is explored with the focus on design, commissioning and operation processes. Some issues found in the realisation of low energy buildings are highlighted and techniques gleaned from microelectronics proposed as possible solutions. Opportunities identified include: adoption of a more integrated process, use of standard cells, inclusion of controls and operational code in the design, generation of building commissioning tests from simulation, generation of building operational control code (including self-test) from simulation, inclusion of variation and uncertainties in the design process, use of quality processes such as indices to represent design robustness and formal continuous improvement methods. The possible integration of these techniques within a building information model (BIM) flow is discussed and some examples of enabling technologies given

Towards an overheating risk tool for building design

PurposeThe work set out to design and develop an overheating risk tool using the UKCP09 climate projections that is compatible with building performance simulation software. The aim of the tool is to exploit the Weather Generator and give a reasonably accurate assessment of a building's performance in future climates, without adding significant time, cost or complexity to the design team's work.Methodology/approachBecause simulating every possible future climate is impracticable, the approach adopted was to use principal component analysis to give a statistically rigorous simplification of the climate projections. The perceptions and requirements of potential users were assessed through surveys, interviews and focus groups.FindingsIt is possible to convert a single dynamic simulation output into many hundreds of simulation results at hourly resolution for equally probable climates, giving a population of outcomes for the performance of a specific building in a future climate, thus helping the user choose adaptations that might reduce the risk of overheating. The tool outputs can be delivered as a probabilistic overheating curve and feed into a risk management matrix. Professionals recognized the need to quantify overheating risk, particularly for non‐domestic buildings, and were concerned about the ease of incorporating the UKCP09 projections into this process. The new tool has the potential to meet these concerns.Originality/valueThe paper is the first attempt to link UKCP09 climate projections and building performance simulation software in this way and the work offers the potential for design practitioners to use the tool to quickly assess the risk of overheating in their designs and adapt them accordingly.</jats:sec
