Optimization of MVAC systems for energy management by evolutionary algorithm
(Preprint)Energy management in existing building services installations is an essential focus of contemporary facilities management. The subway company that is one of the major utilities services in Hong Kong Special Administrative ... -
Model-based control of renewable energy systems in buildings
(Article)The paper describes a research project concerned with the problem of supervisory control of systems which combine a range of heat sources with active and passive thermal storage. The work is based around a prototype building ... -
HVAC system configurations: an energy aspect
(Article)This paper studies the energy implications of HVAC system configuration by analysing energy balance and psychrometrics of typical and innovative systems. Three criteria have been established: (1) the ability to minimize ... -
Modeling the dynamic response of conduits

HVAC system optimization for energy management by evolutionary programming
(Article)Energy management of heating, ventilating and air-conditioning (HVAC) systems is a primary concern in building projects, since the energy consumption in electricity has the highest percentage in HVAC among all building ... -
The cooling potential of earth-air heat exchangers for domestic buildings in a desert climate
(Article)A theoretical model of an earth–air heat exchanger (EAHE) isdeveloped for predicting the outlet air temperature and cooling potential of these devices in a hot, arid climate. The model is validated against other published ... -
A multi-operational ventilated photovoltaic and solar air collector: application, simulation and initial monitoring feedback
(Article)This paper concerns the application of the first European example of a roof mounted, multi-operational ventilated photovoltaic and solar air collector, development of a detailed simulation methodology for such a system, ... -
Simulation of the operation of a climatic wind tunnel
(Article)The climatic wind tunnel (CWT) is a facility which is widely used in vehicle and component manufacturing to reduce product development times. In view of the wide range of temperatures, humidities and wind speeds required ... -
Comparing and combining theories to explain proenvironmental intentions: the case of commuting-mode choice
(Article)This article addresses the need for systematic theory comparison and development in environmentally significant behavior (ESB) research. Using logistic regression (N = 398), models based on Schwartz’s norm-activation theory ... -
Some new thoughts on Gauss-Laguerre quadrature
(Article) -
Branch and bound algorithms for rate-distortion optimized media streaming
(Article)We consider the problem of rate-distortion optimized streaming of packetized multimedia data over a single quality-of-service network using feedback and retransmissions. For a single data unit, we prove that the problem ... -
MIMO-OFDM-based DVB-H systems: a hardware design for a PAPR reduction technique
(Article)Digital video broadcasting - handheld (DVB-H) is the technology driving mobile TV, which uses orthogonal frequency division multiplexing (OFDM) systems with multiple-input multiple-output technology (MIMO). These mobile ...
