The objective of this study is to develop guidelines for thermal comfort and energy efficiency for senior centers during winter. The study was conducted in Phitsanulok, Thailand and it applied 3 study’s methods; field survey, laboratory study, and simulation in scSTREAM–a CFD program and DOE-2 program; to develop the guidelines. With a temperature set-point at 25.0°C in the existing air-conditioned senior centers, the study shows that occupants feel "Slightly cool". These feeling can be adjusted to "Neutral" by applying natural ventilation and fans to generate air speed of 0.57–0.60 m/s during 8:00 AM–1:00 PM, and by setting the temperature set-point at 26.0°C with air speed of 0.10–0.26 m/s during 1:00 AM–4:00 PM. The guidelines can help reduce energy consumption by 23.0 % and can apply for senior centers.
