The Roof Savings Calculator (www.roofcalc.com) provides the general public with a web-based program for calculating the energy savings of different roofing and attic systems on four different building types (residential, office, retail, and warehouse) in 239 US TMY2 locations. The core simulation engine of the RSC is doe2attic, which couples the AtticSim program developed by Oak Ridge National ...

The purpose of this study is to analyse the human response indoor climate with two individually controlled convective and radiant cooling systems: a low velocity unit combined panel system (LVRP) personalized ventilation (PVRP). As reference without individual control, diffuse ceiling (DCV-RP) was also studied. In laboratory conditions, 10 males females gave subjective during various office act...

This research investigated the exergy enhancement performance of a hybrid radiant cooling system adapting to hot and humid summer conditions through comparative case studies analyses. study suggested three systems: general all-air (AAS), conventional (CRCS), (HRCS). As study, an office building with systems was examined in season four different cities: Beijing, Shanghai, Chengdu, Guangzhou, Chi...

In the present work, human thermal comfort is investigated within the built environment. The analysis is based on two building thermal simulation models. In the first one Nodal Network – the air condition (such as, air temperature and velocity) within each thermal zone is assumed uniform and therefore, all zone occupants are exposed to the same condition. In the second model – Nodal NetworkCFD ...

[1] Aerosols over the Northeastern Pacific Ocean enhance the cloud drop number concentration and reduce the drop size for marine stratocumulus and cumulus clouds. These microphysical effects result in brighter clouds, as evidenced by a combination of aircraft and satellite observations. In-situ measurements from the Cloud Indirect Forcing Experiment (CIFEX) indicate that the mean cloud drop num...
