This paper describes the development of a modelling approach which combines the energy use in industrial production, with the energy flows relating to the building. Through case studies, the effects of energy conservation measures in production on the overall thermal energy balance of a factory production area are explored. The paper identifies three types of manufacturing processes; thermal ‘air’ process (oven), thermal ‘fluid’ process (vat) and electrical processes (motor).

Passive Downdraft HVAC systems are natural ventilation systems that add heating and cooling to the passive airstream to control zone temperatures and enhance the flow of air by affecting buoyancy forces.  This paper reviews different analysis approaches used to study the performance of this HVAC approach.

Based on the authors’ previous works, this paper describes a new methodology that uses a bottom-up approach for accurately calculating the time series utility loads (e.g., energy, power, city water, hot water, etc.) for multi-dwelling systems, including residential buildings, residential block areas, and even the entire city. This calculation considers the behavioral variations of the inhabitants of the dwellings.

A holistic strategy to significantly reduce carbon emissions in the residential housing sector will involve the design and delivery of new houses with low or zero emissions. This paper presents a new tool for the design of individual low-emission and zero-emission houses in Australia. Based on the engine of CSIRO's AccuRate house energy efficiency rating software but with new modules and capabilities, the AusZEH Design tool combines a whole house energy consumption tool with a supply-demand matching optimisation model.

The human dimension of building performance simulation can be approached from different vantage points. This contribution addresses the following three. First, building simulation tools and environments need to exhibit a high degree of usability. They are expected to provide effective support  for  generating  building  models  and processing simulation results. Second, the representation of people's presence and actions in building  simulation  models  requires  a  sound empirical basis. It must be properly gauged toward applicable objectives of the modeling activity.

Current interest in building energy efficiency is driving an increase in demand for building energy modelling (BEM) services. Yet practitioners are challenged to deliver BEM services effectively and consistently. Contributing to this is an expansive knowledge requirement, the lack of standardized methods and the absence of defined processes. This paper introduces the concept of a BEM methods and processes (M&P) framework.

Over the last three years the understanding, adoption and use of BIM has gained international momentum.
