This Decision Regulation Impact Statement (RIS) examines the expected impacts, including costs and benefits, associated with a proposal to add separate heating and cooling load limits or ‘load limits’ to the current Nationwide House Energy Rating Scheme (NatHERS) compliance pathway for the energy performance of residential buildings in the National Construction Code (NCC, or the Code).

Urban centres are a major source of greenhouse gas emissions and energy use. In Australia, Building energy use is responsible for 23% of greenhouse gas (GHG) emissions, more than half of which comes from the residential sector (CIE, 2007). In Australian residential homes, about two thirds of energy is used for heating and cooling (incl. water) (CIE, 2007).

AIRAH undertook this project on behalf of the whole of industry to provide a forum or mechanism whereby the transition to low -­‐ emission HVAC&R practices and technologies could be discussed openly and transparently. The topic is broad and the views are varied and often conflicting. The content of this paper is based on submissions rece \ived from industry stakeholders.

This paper demonstrates that the integration of passive features during the design/construction of sustainable buildings requires thorough modelling at the design stage as some features may have unintended consequences resulting in occupant dissatisfaction, and resulting in the building using more energy to maintain comfort.

One of the major obstacles to improving solar thermal cooling technologies is the high operating temperature requirements of most solar thermal cooling systems. This paper reviews recent advances that could reduce the required heat source temperatures for solar desiccant cooling to the range of 50°C–60°C. These approaches include (i) isothermal dehumidification (e.g.

Greenhouse gas emissions urgently need to be reduced. Even with a step up in mitigation, the goal of limiting global temperature rise to well below 2 °C remains challenging. Consequences of missing these goals are substantial, especially on regional scales. Because progress in the reduction of carbon dioxide emissions has been slow, climate engineering schemes are increasingly being discussed.

Radiant cooling and heating has the potential for improved energy efficiency, demand response, comfort, indoor environmental quality, and architectural design. Many radiant buildings have demonstrated outstanding performance in these regards, and application of the technology in commercial buildings is expanding.

This study analysed over 1.8 million measurements of air conditioner power consumption and indoor/outdoor air temperatures in 129 houses in Adelaide, Brisbane and Melbourne from 2012 to 2014. It was found that the preferred indoor air temperature range, at which occupants are most unlikely to operate air conditioners, increases for warmer local climates.

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.
