DAYLIGHT1-2-3 - a State-Of-The-Art Daylighting/Energy Analysis Software for Initial Design Investigations (original) (raw)

Evaluation of Daylight in Buildings in the Future

2015

Building regulation requirements and traditional engineering practice for daylight calculations is often outdated and unsynchronized with the advance and needs of modern sustainable building design. State-of-the-art calculation tools provide accurate results on daylight conditions using methods as simple as calculating the useful daylight illuminance. These methods facilitate sustainable building design that also works in practice. This is illustrated with an example where the daylight conditions in an office with different types of solar shading is examined.

Advanced Daylighting Technologies for Sustainable Architecture Design

Abstract Daylighting has been a part of built forms throughout architectural history. Interest in using daylighting as a major design element has varied with the social and economic forces of the time. Since 1973, interest in daylighting has increased as a result of oil embargo and the understanding that electric lighting represents a major energy consumer. Energy savings achieved through the use of daylight also translate into energy cost savings from reduced electricity consumption for lighting and cooling as well as from reduced needs during peak demand periods in many building. The objective of this paper is to explain the great importance for daylighting and the role played in design process for the building and the participation in the design from the first step which effects the designer decision for dimensions, position for the opening and the building orientation, etc... Which give the psychological comfort for building user and how to control the heat transfer throw opening by using different materials and using simulation programs which give to the designer a clear image for what will be a situation all the year around? Keywords: Daylighting, Simulation, Sustainability, Daylighting Calculation.

The Application of Daylighting Software for Case-study Design in Buildings

Proceedings of the 35th International Conference on Education and Research in Computer Aided Architectural Design in Europe (eCAADe) [Volume 1]

The application of different software, whether simple or complex, can each play a significant role in the design and decision-making on daylighting for a building. This paper, discusses the task to be accomplished, in real case studies, and how various lighting software programs are used to achieve the desired information. The message iterated throughout the paper is one that respects, and even suggests, the use of even the simplest software, that can guide and inform design decisions in daylighting. Daylighting can be complex since the position of the sun varies throughout the day and year as well as do the sky conditions for a particular location. Just because we now have the computing capacity to model every single minute of a day throughout a year, doesn't justify its task. Several projects; an architecture studio, a university office building, a school library and a gymnasium all present different tasks to be achieved. The daylighting problems, the objects and the software application and their outcomes are presented in this paper. Over a decade of projects has led to reflecting upon the importance of computing in daylighting, its staged approach and the result that it can achieve if properly applied.

Proposed Framework for Daylight-Focused Homes during Design Development

International Journal of Engineering Technologies IJET

Solar decathlon is held biannually, and participant universities have a unique chance to locate solar houses on campus as a living lab after the contest. A variety of performance criteria are evaluated during the contest and daylighting is one among them. Complicated analysis tools, design solutions, and their effectiveness are major challenges during the design development of new solar houses. This challenge definition leads to developing a daylighting guideline for new solar house design. To provide a roadmap of validity of emerging daylighting metrics, demonstration of the daylighting performance of built-up solar houses, and daylighting guideline for design parameters with recent technology on new solar house design are the specific objectives of this study. The manuscript aims to examine the existing daylighting design tools while proposing a roadmap for how to use emerging metrics over solar house design.

The daylighting dashboard � A simulation-based design analysis for daylit spaces

Building and Environment, 2011

This paper presents a vision of how state-of-the-art computer-based analysis techniques can be effectively used during the design of daylit spaces. Following a review of recent advances in dynamic daylight computation capabilities, climate-based daylighting metrics, occupant behavior and glare analysis, a fully integrated design analysis method is introduced that simultaneously considers annual daylight availability, visual comfort and energy use: Annual daylight glare probability profiles are combined with an occupant behavior model in order to determine annual shading profiles and visual comfort conditions throughout a space. The shading profiles are then used to calculate daylight autonomy plots, energy loads, operational energy costs and green house gas emissions. The paper then shows how simulation results for a sidelit space can be visually presented to simulation non-experts using the concept of a daylighting dashboard. The paper ends with a discussion of how the daylighting dashboard could be practically implemented using technologies that are available today.

Daylighting Strategies: Building’s Sustainability and Energy Efficiency

Journal of Civil Engineering and Architecture, 2013

Improving daylighting strategy is a mandatory step to achieve visual enjoyment and energy saving in buildings. Psycho, physiological effects and energy performance have to be investigated in order to define a range of different daylighting strategies, thanks to daylighting devices and climate based daylight modeling. Daylighting optimization ensures indoor healthier rooms, reduces electric light consumption and cuts the risk of glare. The best way to achieve these targets is to define users lighting needs, based on visual targets and to draw up some green measures to reduce electricity demands. Involving new climate-based daylight modeling metrics aims at defining proper illumination targets, in order to drastically reduce electrical lights, as well as reducing thermal loads deriving from cooling and HVAC (heating, ventilation and air conditioning) systems.
