ASHRAE members have free access to research project final reports. Non-ASHRAE members can purchase research reports for $30 per article from the ASHRAE Bookstore found at this link.

The following research projects have been completed:

1413-RP:  DEVELOPING STANDARD PROCEDURES FOR FILLING CLIMATIC DATA GAPS FOR USE IN BUILDING PERFORMANCE MONITORING AND ANALYSIS

The objectives of this proposed effort are to develop standard procedures, in the form of an ASHRAE Toolkit, for filling in missing measured climatic data and to verify the robustness of these procedures by testing them for several actual and synthetic data from the appropriate case study sites.  Key climatic variables of interest include (but are not limited to): dry-bulb temperature, dew-point and wet-bulb temperature, wind speed and direction, total, diffuse, and direct normal solar radiation.  It is further anticipated that different procedures will be needed depending on the type of missing climatic data (e.g., temperature, humidity, wind, solar).  For example, the interpolation of missing temperature data might be best performed with one method, whereas the interpolation of missing wind speed or solar data would need another.

1613-RP:  UPDATE CLIMATIC DESIGN DATA IN CHAPTER 14 OF THE 2013 HANDBOOK OF FUNDAMENTALS
Co-sponsor, TC 4.1 Load Calculation Data and Procedures

The climatic design conditions in the HOF Chapter 14 are fundamental for the sizing and design of building energy systems to allow for optimal energy efficiency measures and ensure that the design conditions are related to the energy system capacity to meet the climatic loads in a probabilistic sense. Regular updating of the climatic conditions is critical in this respect for many practical reasons and to show due diligence in a world of changing climate.

1699-RP: UPDATE CLIMATIC DESIGN DATA IN CHAPTER 14 OF THE 2017 HANDBOOK OF FUNDAMENTALS
Co-sponsor, TC 4.1 Load Calculation Data and Procedures

ASHRAE Research Project 1699 (RP-1699) sought to
- Update existing Handbook locations and introduce new locations based on recent observational data;
- Add climatic elements based on the needs of the membership;
- Investigate the data for any long term trends; and
- Update the Handbook and Standard tables and climate maps.
The project lead to the update of Chapter 14 in the 2017 Handbook of Fundamentals, a revision of Standard 169, and a new version of the Weather Data Viewer.
