Influence of component selecting size method of hydronic networks on global costs and comfort | 2005 | English
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.
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.
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 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.
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.
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.
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
This paper presents first steps of a methodology for calibration of building simulation models through definition of the parameters that most affect the main electric end-uses of a building.
This paper presents the results of a comparison between measurements of a co-heating test in a passive house and the simulated response of the building to the same outdoor conditions calculated with the building simulation program Trnsys. Special
An efficient urban energy system could be a highly diverse and well-integrated structure of buildings and systems.
This paper presents CFD simulations of natural displacement ventilation airflows in which the buoyancy force produced by a heat source is opposed by a wind force.
This paper describes the design and simulation of a hybrid ventilation system for a recently constructed circus building in Montreal. The HVAC system draws fresh air through two underground ducts which are used for preheating or precooling.
Energy and financial performance of micro-chp in connection with high-performance buildings | 2005 | English
This paper deals with the issue of using micro- Combined Heating and Power plants (mCHP) in high-performance houses in terms of energy conservation and cost savings.
