Performance of thermal distribution systems in large commercial buildings

Thermal performance of photovoltaic systems integrated in buildings

One might at first believe that knowledge of the photovoltaic effect is recent. In fact, we must go back to 1839 with the French physicist Edmund Becquerel who first discovered the photovoltaic effect. It was during the period between the second half of the 19th and the Second World War (1945) that scientific knowledge related to solar phenomena were mastered. Thus, in 1875, Werner von Siemens ...

coordination of protective schemes in distribution and subtransmission systems including distributed generation

نصب منابع پراکنده در سیستم های توزیع و فوق توزیع علاوه بر مزیت های فراوان، مشکلاتی را هم به همراه دارد. یکی از این مشکلات تأثیر این منابع روی اندازه جریان های اتصال کوتاه است. به طور معمول از حفاظت های مبتنی بر اصل جریان زیاد در سیستم های توزیع و فوق توزیع استفاده می شود. از مهمترین طرح های حفاظتی استفاده شده در فیدرهای توزیع، حفاظت فیوز- ریکلوزر است. همچنین از طرح های حفاظتی جریان زیاد جهتی در...

Methodology for Commercial Buildings Thermal Loads Predictive Models Based on Simulation Performance

Commercial buildings incorporate Building Energy Management Systems (BEMS) to monitor indoor environment conditions as well as controlling Heating Ventilation and Air Conditioning (HVAC) systems. Measurements of temperature, humidity and energy consumption are typically stored within BEMS. These measurements include underlying information regarding building thermal response, which is crucial fo...

An Inverse Model to Predict and Evaluate the Energy Performance of Large Commercial and Institutional Buildings

1 Present address: Energy Systems Laboratory, Texas A&M University, College Station, TX 77843-3123, USA. ABSTRACT A new method for predicting and evaluating the energy performance of large commercial and institutional buildings is developed, as an alternative to using existing comprehensive energy simulation programs like DOE-2 and BLAST, or oversimplified tools like analyzing monthly utility b...
