This paper provides a snapshot of future HVAC in a net-zero world, and outlines some of the mainthemes from the workshop discussions such as:
The changing relationship between occupants and buildings;
A shift in the approach and objectives for town planners;
A move to low energy HVAC technologies including step changes in controls;
A regulatory focus on building performance rather than construction;
Extension of government regulation into operational energy use.
Following an analysis of the most likely changes that are needed and the most common barriersthat may be encountered a series of recommendations or actions have been developed to helpgovernment and industry understand how the HVAC and property sectors can best transition todelivering and managing net-zero energy buildings.

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.
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.
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.
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.
