Conservation and Solar Buildings
The committee emphasizes design, analysis and monitoring of green, zero-energy and passive buildings and energy conserving buildings, including retrofit strategies.  The scope of activity includes envelope dominated buildings and internal gain dominated buildings with all aspects of envelope and building energy system performance considered.  Recent activities have emphasized the energy-related aspects of building performance, but in the future the committee will also include the topic of human comfort.

Heating and Cooling Applications and Analysis
The committee is involved in the design, analysis, testing and measurement, economics and experimental performance of solar heating and cooling systems, components and materials.  The scope of the committee's activities includes solar space heating, solar water heating, solar preheat ventilation, thermally driven desiccant cooling, absorption cooling, energy storage, and advanced solar collectors for heating and cooling applications.

Photovoltaics
This technical committee provides a forum for describing the technologies related to the terrestrial conversion of solar energy into electricity by direct conversion.  All aspects of photovoltaic energy conversion including manufacturing, electrical conversion, system design, testing and measurement, economics, and applications are within the scope of this committee.

Solar Thermal Power
This committee is involved in the conversion of solar energy into high-temperature thermal energy and thermal-electrical power.  Because of the importance of high temperatures in these processes, concentrating collectors, thermal receivers, heat engines as well as analytical and experimental systems analysis are of interest to the committee.  Topics of sessions sponsored by the Committee at past conferences include concentrating collectors, receivers, heat engines, and dish-engine and central receiver systems.

Wind Energy
The committee works on all aspects of wind energy technology including aerodynamics, machine design, controls, utility issues and small turbine applications.

Solar Fuels
This committee focuses on using concentrated solar power to drive thermochemical processes and cycles to convert sunlight to energy carriers – solar fuels. Solar fuels can be stored and transported great distance from sunny desert regions to highly populated areas where the energy is required and overcome the primary disadvantages of solar radiation: dilute, intermittent, and unequally distributed.  Recent activities of this committee have concentrated on multistep thermochemical cycles and chemical processes that use concentrated solar power as the source of process heat.

Sustainable Cities & Communities
Sustainable communities or neighborhoods are the basic building blocks for creating an energy-efficient and eco-friendly city. The committee emphasizes the design, monitoring, and modeling of an integrated energy system at community and city scales. The scope of the committee's activities including, but not limited to, solar heating and cooling, building integrated photovoltaic (BIPV) , high performance buildings, thermal storage, high efficient urban infrastructure, district heating and cooling, building cooling heating and power (BCHP) based on renewable fuels, and related public policy.  Topics of sessions sponsored by the committee at past conferences include green energy infrastructure case study, innovative simulation and analysis method, and renewable energy and energy policy in urban infrastructure.
