Abstract The objective of this document is to promote the use of dynamic daylight performance measures for sustainable building design. The paper initially explores the shortcomings of conventional, static daylight performance metrics which concentrate on individual sky conditions, such as the common daylight factor. It then provides a review of previously suggested dynamic daylight performance metrics, discussing the capability of these metrics to lead to superior daylighting designs and their… Expand
Daylight metrics and energy savings
The drive towards sustainable, low-energy buildings has increased the need for simple, yet accurate methods to evaluate whether a ‘daylit’ building meets minimum standards for energy and humanExpand
Improving Prediction of Daylighting Performance
Daylighting is an essential strategy to get to zero energy commercial buildings. However, simplistic metrics that cannot account for climate, location, orientation or advanced technologies have madeExpand
Daylighting performance of subtropical multi-residential towers : simulations tools for design decisions
During an intensive design-led workshop multidisciplinary design teams examined options for a sustainable multi-residential tower on an inner urban site in Brisbane (Australia). The main aim was toExpand
A New Dynamic Climate-Based Daylight Metric for Sustainable Building Design in Hot Climates
Daylight performance metrics are moving away from the traditional daylight factor and average illuminance to more climatic-based metrics such as Daylight Autonomy (DA) and Useful Daylight IndexExpand
A critical review of daylighting metrics for residential architecture and a new metric for cold and temperate climates
It is found that existing workflows often overlook relevant aspects of daylight in residential spaces, such as diurnal and seasonal availability of daylight and access to direct sunlight, and a concept for a new climate-based, annual evaluation framework that overcomes these shortcomings is introduced.

Assessment of climate-based daylight performance in tropical office buildings: a case study
The utilization of daylight can significantly affect building performance, energy efficiency, productivity, as well as occupants' comfort and satisfaction in buildings. This paper aims to assessExpand
Climate-based Daylight Metrics Applied for Sustainable and High-quality Design Strategy of Office Spaces
To evaluate the daylight condition of Taiwan’s office space, this study used the " Typical Meteorological Year" as the database of climate, and applied the dynamic lighting index "Spatial Daylight Autonomy (sDA)" and "Annual solar Exposure value (ASE)" as the dynamic daylight evaluation index, which are commonly used internationally.

Daylighting Metrics for Residential Buildings
It is now widely accepted that the standard method for daylighting evaluation - the daylight factor – is due for replacement with metrics founded on absolute values for luminous quantities predictedExpand
A New Framework for Residential Daylight Performance Evaluation
Current climate-based daylighting metrics have limited applicability for residential use cases and fail to highlight relevant aspects of natural light in residential spaces, such as diurnal andExpand
Proposal of a façade design approach for daylight performance determination in buildings
Proposed process consists of determination stages based on daylight illuminance, control of glare and view out conditions, and aims to describe current daylight metrics that can be used for façade design and applications. Expand


Examples of Climate-Based Daylight Modelling
The daylight factor persists as the dominant evaluation metric because of its simplicity rather than its capacity to describe reality. The daylight factor is insensitive to both the prevailing localExpand
Useful daylight illuminance: a new paradigm for assessing daylight in buildings
A new paradigm to assess daylight in buildings called ‘useful daylight illuminance’, or UDI, is introduced, founded on an annual time-series of absolute values for illuminances predicted under realistic skies generated from standard meteorological datasets. Expand
Simulation of annual daylighting profiles for internal illuminance
A true measure of the long-term daylighting performance of a building must account for the illumination that results from a wide range of sky and sun conditions. This paper describes how to predictExpand
Useful daylight illuminances: A replacement for daylight factors
The UDI paradigm is designed to aid the interpretation of climate-based analyses of daylight illuminance levels that are founded on hourly meteorological data for a period of a full year, and is well-suited for teaching purposes. Expand
Dynamic annual daylight simulations based on one-hour and one-minute means of irradiance data
Abstract This study investigates the influence of the short-term dynamics of daylight on simulation-based predictions of the annual daylight availability in a building. To this end annual indoorExpand
Effects of Interior Design on the Daylight Availability in Open Plan Offices
The COPE (cost-effective open plan environments) project investigates the effect of open-plan office design on the indoor environment and on the occupant satisfaction with that environment. COPE isExpand
Comparison of control options in private offices in an advanced lighting controls testbed
It is found that the energy savings due to occupant sensing vs. dimming depended on the behavior of occupants, and in offices whose occupants tended to stay at their desks all day, dimming controls saved more energy, and vice versa. Expand
Findings from a survey on the current use of daylight simulations in building design
Abstract This paper presents findings from a web-based survey on the current use of daylight simulations in building design. The survey was administered from December 2nd 2003 to January 19th 2004.Expand
