The New Zealand building design industry assumes various building model inputs for the consumption of energy through lighting and appliances. It also makes assumptions regarding when these energy consumers are considered to be “turned on”. This paper aims to better inform industry energy modellers about the real load and operation of real commercial buildings in New Zealand when compared to New...

This paper is concerned with the development of data-driven predictive models capable of forecasting commercial building heating loads based on BEM (Building Energy Management) systems recorded variables, as well as weather data. To address the lack of available complete datasets from actual commercial building BEM systems, a detailed representation of a reference building using EnergyPlus was ...

With energy resource scarcity and energy crisis in the world, energy efficiency has become a subject of great importance. In warm and humid climates as well as cold and mountainous ones, annual energy consumption is too high to achieve desirable living conditions in built environments, and hence energy efficiency measures and practices in such buildings is of utmost priority. Given the direct r...

Solar shading designs are important for reduction of building energy consumption and improvement of indoor thermal environment. This paper carried out a number of building simulations for evaluation of the energy performance of different shading devices based on incremental costs. The results show that movable shading devices lower incremental costs by up to 50% compared with fixed ones for the...

We study providing ancillary service to the power grid by using the flexibility of HVAC (Heating, Ventilation, Air Conditioning) systems in commercial buildings. The building HVAC system’s thermal and power consumption models are constructed and key model parameters are estimated from measure data from Pugh Hall of University of Florida. We develop a method for optimal output tracking of a time...
