Article
Full-text available
A simulation algorithm and its implementation into three building simulation programs are presented. The algorithm predicts the lighting energy performance of manually and automatically controlled electric lighting and blind systems in perimeter daylit offices. Algorithm inputs are annual profiles of user occupancy and work plane illuminances. Thes...
Article
Energy use in buildings is closely linked to their operational and space utilization characteristics and the behavior of their occupants. The occupant has influence due to his presence and activities in the building and due to his control actions that aim to improve indoor environmental conditions (thermal, air quality, light, noise). Due to the de...
Article
Building performance simulation has been used to provide a plausible estimate of the operational performance that could be expected from a mature-technology version of a Stirling engine (SE) residential cogeneration system. This was accomplished by applying lessons learned from investigating the actual performance of a prototype SE system. Simulati...
Article
Full-text available
The daylight coefficient method is a powerful and efficient method to perform annual daylight illuminance simulation. A set of coefficients are calculated for a given room space and static fenestration systems prior to simulation start. Time series of indoor daylight illuminances are obtained by only knowing the sky luminance. However, for rooms wi...
Article
Full-text available
Daylight coefficients are normalized contributions from discretized sky or ground segments, or preset solar positions, to solar quantities calculated at various building sensor points. Once generated, daylight coefficients can be folded against luminance efficacy and distribution models to calculate, for instance, time series of illuminances. Over...
Article
Full-text available
A performace assessment study has been performed on the application of Stirling engine (SE) and Solid Oxide Fuel Cell (SOFC) residential cogeneration systems in single family detached houses in Canada. Detailed mathematical component models, calibrated with measured data from prototypes, were combined into the whole-building simulation program ESP-...
Article
Full-text available
This paper presents a set of solutions to enable differential time scales for dynamic boundary conditions within whole-building energy simulation, specifically occupant behavioral adaptations in response to short-term changes in solar and daylighting conditions. The concept is to allow specialized libraries to determine in tandem the state of criti...
Article
Full-text available
This paper describes a methodology for calculating the daylight coefficient for complex fenestration systems whose optical behavior (transmission, reflection and scattering) may change during simulation. The methodology splits the daylight coefficient into two components: one corresponding to the unscattered transmitted light and the second to the...
Article
Behavioural models derived from on-going field studies can provide the basis for predicting personal action taken to adjust lighting levels, remedy direct glare, and save energy in response to physical conditions. Enabling these behavioural models in advanced lighting simulation programs, such as DAYSIM and the Lightswitch Wizard, allows for a more...
Conference Paper
Full-text available
Behavioural models derived from on-going field studies can provide the basis for predicting personal action taken to adjust lighting levels or remedy direct glare in response to physical conditions. SHOCC, a sub-hourly occupancy-based control model, provides building energy simulation programs, such as ESP-r, access to advanced behavioural models,...
Conference Paper
Full-text available
A wide range of events in buildings occur at sub-hourly frequencies. Notable examples include daylight-sensing control and manual adjustment of blinds and lights in response to sub-hourly illuminance variations. Such short-term changes can produce notable shifts in instantaneous solar and equipment loads, in turn affecting electrical energy demand....
Article
Full-text available
This paper provides a background review of various models for predicting occupancy, occupancy-sensing control and manual environmental control for buildings, and outlines their current addition to whole building energy simulation, in particular ESP-r. It also deals with another assumption that may need revising in light of sub-hourly time discretiz...
Article
Full-text available
Annex 35 is an International Energy Agency (IEA) task-sharing project in which participate 15 countries, including Canada. Its objective is to study and promote hybrid ventilation in new and retrofitted office and educational buildings. Part of the project is to study the application of hybrid ventilation through different pilot studies in various...
Article
Full-text available
Within the scope of an environmental study of the New Caisse de dépôt et placement du Québec (CDP) Headquarters in Montreal, the energy conservation performance of a double façade design is compared against conventional double and triple glazing units, using a procedure based on numerical modeling and experimental data. Results suggest that while d...
Article
Full-text available
Environmental and economic concerns linked to conventional heating, ventilation and air-conditioning systems (HVAC) have sparked a renewed interest in natural ventilation, passive cooling and other low- energy microclimate control strategies for buildings. In Canada, the combination of extreme weather conditions, wind variability, transient occupan...
Article
Full-text available
This paper provides an overview of Daylight1-2-3, a new daylighting/energy analysis software for design professionals and architectural students with an interest in daylighting and sustainable design, but no required previous knowledge of either daylighting concepts or simulations. The initial version of Daylight 1-2-3 focuses on private offices, o...
Article
Cette étude a pour but de combler l'écart entre l'état actuel de la simulation énergétique dans le domaine du bâtiment (i.e. hypothèses et modèles) et la connaissance empirique sur le comportement des usagers en matière de contrôle environnemental. L'application principale issue de cette thèse est un module de simulation autonome qui vise la modéli...
Article
Full-text available
This paper provides a background review of models predicting occupancy, occupancy-sensing control and manual environmental control, and outlines their current addition to whole building energy simulation, in particular ESP-r. It deals with how occupancy-related input data models are defined and used in whole-building energy simulation. Dans ce docu...
Article
Full-text available
This paper presents the results of a Radiance-based intermodel comparison between the validated Daysim daylight coefficient model and a new standard model for dynamic daylighting simulations (DDS). The new model offers independence from site location and orientation, estimation techniques and simulation applications. The standard data can be used f...
