Comparison of expansion valve performance 95104035 Hewitt, N. J. er al., Int. J. Energy Res., Jun. 1995, 19, (4), 347-359. The paper compares the performance of a’thermostatic expansion valve, thermoelectric expansion valve, solenoid expansion valve and a motorized type operating as part of an extensively controlled and instrumented refrigeration system. It will be shown that the solenoid expansion valve provides the best control. Cost-optimal analysis of cooling towers QSlO4036 Kinter-Mever. M. ASHRAE Trans., 1994, 100, (21, 92-101.

Design considerations of primary performance parameters for irreversible refrigeration cycles
95/04047 Energy, comfort, amenity and solar efficient design Samuels, R. Proc. Solar ‘94, ANZSES Administrator, PO Box 124, Caulfield East, VIC.3145, Australia. The paper discusses the National Evaluation of Energy Efficient Houses project which was carried out in the Adelaide, Sydney and Melbourne regions between 1989 and 1990, and in the Perth region in 1991. The objective was to uncover occupant or user experiences of the houses, in terms of their attitudes and behaviours relating to the energy used in the running of their houses.

Reports that indoor summer comfort provided by an energy-efficient display house has proved superior to the performance of a conventional house in a trial conducted by the Energy Information Centre of the Department of Minerals and Energy, Australia. 95104049
Estimation of continuous-time models for the heat dynamics of a building
Madsen, H. and Holst, J. Energy & Buildings, 1995, 22, (l), 67-79. The paper describes a method for estimation of continuous-time models for the heat dynamics of buildings based on discrete-time building performance data..The parameters inihe continuous-time model are es&rated by the maximum likelihood method where a Kalman filter is used in calculating the likelihood function. The modelling procedure is illustrated by using measurements from an experiment where the heat input from electrical heaters is controleld by a pseudorandom binary signal. For the considered building a rather simple model containing two time constants is found adequate. Owing to the continuous-time formulation the parameters of the model are directly physically interpretable. The performance of the model for both forecasting and simulation is illustrated.

Design of a fuzzy set environment comfort System
Dounis. A. I. et al.. Enerev & Buildinns. 1995. 22. (1). 81-87. The paper presents the des&n of a fuzzy reasoning expert system for the achievement of thermal and visual comfort in buildings. This system does not demand the precise mathematical model of the building to achieve the control law but uses high-level control variables such as thermal and visual comfort. The powerful interactions of the passive components and of the comfort subjectivity match with the application of the fuzzy control theory entirely. Mathemattcal models are presented, where the acttons of the actuators are applied. The design of the rule base is described and, finally, the system is evaluated by using extensive, worst-cast, simulation results.

Findings from a low-energy, new commerciai-buiidings research and demonstration pro]ect
95104051
Piette, M. A. et al., Energy, Jun. 1995, 20, (6), 471-482. Energy edge (EE) was a research-oriented demonstration project that began in 1985; 28 buildings were constructed to use 30% less electricity than a hypothetical simulated baseline building. Average energy savi s for 18 buildings evaluated with post-occu any tuned simulation models s ere less at 17%. Only six met the costs o F conserved (CCE) energy. 41% of the individual energy-efficiency measures met the target CCE. The cost effectiveness of the measures would have been greater if the baseline had been common practice rather than the regional building code. The EE small offices use about 30-50% less energy than comparable buildings. Savings also would have been greater if commissioning was included within the program. Future projects should consider lower-cost ‘hands-on’ evaluation techniques with annual check-ups to ensure persistence of savings.
