"What impacts does increasing airtightness have on mould, condensation and measures of indoor air quality?"
Leaky homes need more energy to keep warm or cool. Sealing the gaps in a house, or increasing airtightness, is a common tip to reduce energy consumption, as well as make the house more comfortable to live in. However, people need a certain amount of...
A significant portion of the carbon and greenhouse gas emissions of residential buildings in Australia is associated with energy consumption for comfort and health.
This project investigates hybrid solutions using enhanced ventilation in order to achieve indoor comfort conditions, reduce energy consumption and carbon emissions, and finally test it in a selected school building located in Sydney, which co-funded this project. In order to achieve this objective, the following...
Heat recovery ventilators (HRVs) save energy by recovering heat that would otherwise be exhausted as part of energy code-mandated mechanical ventilation systems. Residential HRVs can be life cycle cost effective depending on equipment/installation costs and the severity of the climate. This brief evaluates HRV cost...
Cool roof technology is known to reduce the cooling energy consumption of conditioned buildings during hot periods, and widespread implementation of such roofs in a neighbourhood or precinct can mitigate the urban heat island effect. Established building energy modelling techniques are able in principle to...
The Performance Requirements of the National Construction Code (NCC) can be met using either a Performance Solution or a Deemed-to-Satisfy (DtS) Solution or a combination of both solutions. The following demonstrates the performance based design process that should be used in conjunction with the Development...
The Australian Building Codes Board (ABCB) and the former Australian Department of the Environment, Water, Heritage and the Arts (DEWHA) developed this Handbook to assist users with the application and understanding of the National Construction Code (NCC) Volume One energy efficiency provisions.
Buildings and the atmosphere are intrinsically connected via cooling and heating systems. Global climate is projected to grow warmer, while an increasing fraction of the population living in urban centers. This introduces the challenge for new approaches to project future energy demand changes in cities...
Evaluation of next-generation automated fault detection & diagnostics (FDD) tools for commercial building energy efficiency
Beyond expensive building and equipment upgrades and retrofits, re-commissioning (analogous to performing a comprehensive tune-up on your car) and automated fault detection and diagnostics (FDD) for building systems offer significant energy efficiency opportunities in commercial buildings.
