This document was created by the National Renewable Energy Laboratory (NREL) which is operated for the U.S. Department of Energy by the Office of Energy Efficiency and Renewable Energy. It provides information on the EnergyPlus analysis software program.
The EnergyPlus software is intended to provide energy simulations of whole buildings, and determine their level of energy efficiency. Earlier versions of the program were based on the Heat Balance Model, and measured standard indicators of energy usage such as building envelopes and HVAC systems.
This document, prepared by the International Energy Agency, comes as a follow-up of the 2006 seminar “Renewable heating and cooling – from RD&D to deployment technology and policy” aimed at exploring guidelines and policy initiatives to boost technology development and market deployment for renewable heating and cooling (REHC).
The result from the second tender round of the national rural incentive programme in China: more companies with higher-priced products qualified for it. This year's price limit was RMB 5,000, a substantial increase from the RMB 4,000 last year (10 RMB is about 1 EUR).

This report was prepared in February 2009 by Public Citizen, Environment Texas and Vote Solar. The document looks at the various factors and technology needed to not only supply Texas’ energy needs but make Texas a world leader in solar energy.
Three solar technologies are discussed; photovoltaic (PV), concentrating solar power (CSP) and solar water heaters. The report goes into detail discussing the different variations and advantages each technology possesses. Various charts and photos show applications and cost benefit analysis.
This report prepared by the Polytechnic University in Catalunya gives the reader a complete overview of the Barcelona solar thermal ordinance, created in 2000, and the role of the Barcelona City Council in this regard.
After many weeks of waiting and worrying, it is now official: On 7 July, the budget committee of the German parliament unblocked the EUR 115 million funds intended for the country's market incentive programme (MAP). The German Federal Environment Ministry (BMU), which is responsible for the MAP, confirmed in a press release a day later that, as of 12 July, applications are accepted again.
The differences in hot water demand between families living in the same solar-supplied multi-storey house has always been a source of complaints and disputes in India. A solution was found with the creation of a new hot water management system by Indian company Akson's Solar.

This study and report was prepared by Robert J. Stevens and Richard R. Johnson for the North Carolina Solar Center. The purpose of this study is to first determine, and then test the best low-cost solar pasteurization systems for this potentially viable technology.
The study first examines and describes four concept designs; a thin film polymer pasteurizer with an integral heat exchanger (SPIHX), a, a fully wetted copper SPIHX and a traditional fin and tube absorber with an external heat exchanger (SPEHX).
