1847-RP Updating climatic design information for the 2021 ASHRAE Handbook, Standard 169, and the Handbook of Smoke Control Engineering
Co-sponsors, TC 4.1 Load Calculation Data and Procedures and TC 5.6 Control of Fire and Smoke
This project was tasked with the four-year update of the climatic design tables in the Handbook - Fundamentals, the update of the tables in ANSI/ASHRAE Standard 169: Climatic Data for Building Design Standards Standard, and the calculation of climatic tables in support of the Handbook of Smoke Control Engineering. Its objectives were:
- Recalculate climatic design conditions for Chapter 14 of the Handbook - Fundamentals, using most recent hourly weather observations for the period 1994-2018;
- Provide an analysis of climatic trends (means and extremes) of temperature and moisture, for each location in the Handbook, on a per-station and/or regional basis.
- Update the clear-sky radiation coefficients, based on updated analysis of remotely sensed aerosol data.
- Add new elements such as prevailing wind information, including percent of the month that the most frequent wind directions occur, and mean and median speed of the prevailing winds, in support of the Handbook of Smoke Control Engineering, and the Weather and Shielding Factor (WSF) in support of Standard 169. Prepare a new, web-based version of the Weather Data Viewer.
- Provide tables of climatic design information specific to the ASHRAE Handbook of Smoke Control Engineering.
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.
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.
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.
