A mathematical model applied to building hygrothermal behavior analysis is described in this paper. We have used a lumped approach to model the room air temperature and humidity and a multilayer model in finite volumes for the building envelope.
Delight2 daylighting analysis in energy plus: integration and preliminary user results | 2005 | English
DElight is a simulation engine for daylight and electric lighting system analysis in buildings.
Energuide for houses database – an innovative approach to track residential energy evaluations and measure benefits | 2005 | English
The EnerGuide for Houses (EGH) database is a management information tool and central depository for tracking residential energy evaluations and measuring benefits from the energy evaluations delivered across Canada.
CFD calculations on night cooling by natural ventilation have been carried out for two different opening geometries: 1) a set of panels and 2) a 'parallel window'. Ventilation rates for these geometries have also been measured in a research facili
The tendency to impose stricter building regulations in order to further decrease energy consumption contradicts the tendency to build more transparent architecture and apply thinner façade construction elements.
The evaluation and analysis of available simulation tools suggests a thorough research methodology for creating a new front-end interface that solves current usage problems.
This paper presents a numerical model for the analysis of impact of building envelope porosity on energy.
Cooling load simulation considering actual variation ofinhabitants’ behavior for accurate estimation of urban maximum energy requirement | 2005 | English
A brand-new methodology for considerably accurate time-series cooling load calculation in a dwelling is established, motivated by the fact that dwelling energy requirements so significantly affect the so-called urban heat island.
Elements of a simulation-assisted daylight-responsive illumination systems control in buildings | 2005 | English
This paper presents a simulation-assisted daylightresponsive illumination control system.
Calibrated simulation of the degradation of a solar hotwater system performance over a 22-year period of operation | 2005 | English
This paper reports on the measured performance of a residential solar water heater system over a period of 22 years and the modeling of the system to simulate its degradation over that period.
This paper is about the application of a local (radiant) bench heating system in a church.
Development of a building energy model for carbon reduction in the UK non-domestic stock | 2005 | English
The requirements for a scaleable energy model for the UK non-domestic building stock are described.. The non-domestic stock is much more heterogeneous than the domestic stock.
Assessing sustainability strategies for institutional facilities using cbip screening tool | 2005 | English
Institutional facilities embody the physical infrastructure of the communities they house. Aging institutional buildings, especially those within extensive central campuses, cannot easily be disposed of or abandoned in favour of new facilities.
This paper deals with the use of computer simulations both for design support of a new building including its heating, ventilation and air-conditioning (HVAC) systems and for optimization of the HVAC control strategy during operation of the comple
This paper deals with the dynamical modelling of a solar evacuated tube collector under variable weather conditions. After describing the mathematical model, the paper presents elements of validation.
Buried pipe systems with sensible and latent heat exchange :validation of numerical simulation against analytical solution and long-term monitoring | 2005 | English
A finite differences numerical model for buried pipe systems is presented, accounting for sensible as well as for latent heat exchanges, so as for fully three dimensional heat diffusion in soil and flexible border conditions.
There is a strong demand for accurate moisture modelling since moisture poses a risk for both the constructions and the indoor climate. Thus, in this investigation there is special focus on moisture modelling.
Design standard of energy conservation for building hvac 1system – a simplified method of chiller capacity estimation 2based on building envelope energy conservation index in 3taiwan | 2005 | English
The research developed maximum chiller cooling capacity predicting equations with building shape factor and the ENVLOAD index which is now the building envelope energy conservation design control factor in Taiwan.
To have a proper energy management in buildings, it is necessary to evaluate its HVAC system. To properly compare operating strategies and solve possible problems, one needs to reproduce the building and its HVAC system behavior under real life co
