Technical Highlights, Market Transformation and Outreach
Providing practicing engineers and architects with useful information about these low energy cooling options as well as validated tools is a critical end goal of this work. We have made good progress in reaching these audiences, as noted below.

• LBNL has been assisting in the design of a new Federal Building for San Francisco. The open plan offices that will comprise the majority of the building are to be solely naturally ventilated, with no mechanical cooling or ventilation. EnergyPlus has been used to predict wind and stack driven ventilation flow rates and the resulting thermal performance.
   
• LBNL is working on a DOE-funded NETL project, led by Davis Energy Group, to develop a 'Hydronic Roof Top Unit' for small commercial applications that makes extensive use of evaporative cooling. A detailed simulation program (SPARK) is being used to optimize component sizing within the unit and, in a later phase of the project, the whole building energy simulation program EnergyPlus will be used to assess the performance of the unit in different building types and climates. The possibility of integrating this assessment into the PIER assessment work reported here will be investigated as the work progresses.
   
• LBNL was involved in the organization of two sessions on Low Energy Cooling at the ASHRAE Winter Meeting in Atlanta. Joe Huang organized a Symposium on Analysis Tools for the Design of Low Energy Cooling Systems and Philip Haves organized a Seminar on Low Energy Cooling Case Studies.
   
• UC San Diego organized a two-day meeting in May entitled Natural Ventilation: Towards Low Energy Buildings that brought together researchers and practitioners. There were presentations from our Project 3 leader Paul Linden and from designers from our industrial partners Flack+Kurtz and Ove Arup & Partners. Further details, including presentations, can be found at the meeting's web site.
