DOE Building Technologies Program: Active Solar And Photovoltaic Systems (964 words) |
 | Active solar energy systems should be integrated with a building's design and systems only after passive solar and energy-conserving strategies are considered. |
| An active solar water heating system can be designed with components sized large enough to provide heating for pools or to provide a combined function of both domestic water and space heating. |
| Active solar space-heating systems generally are not operating year-round, so their moving parts must be reliable enough to work intermittently. |

Passive & active solar architecture (2031 words) |
| The rudiments of solar passive design were developed and used through the centuries by many civilisations across the globe; in fact, many of these early civilisations built dwellings that were better suited to their climatic surroundings than those built today in most developed and developing countries. |
| Active cooling systems of solar cooling such as evaporative cooling through roof spray and roof pond and desiccant cooling systems have been developed alongwith experimental stratergies like earth-cooling tubes and earth-sheltered buildings. |
| Active solar systems use solar panels for heat collection and electrically driven pumps or fans to transport the heat or cold to the required spaces. |
