energy performance

The paper was presented by Mr. Jacques Bony and Mr. Stéphane Citherlet from the Laboratory of Solar Energetics and Buildings Physics (Switzerland) in the framework of Task 44 of the IEA Solar Heating and Cooling Programme. It presents the energy and economic performances of facilities coupling heat pumps with air heater equipped with solar thermal collectors. The study was done employing a TRNSYS-type dynamic simulation.

The Decree No. 314/010 was issued by the Uruguayan authorities with the purpose of outlining the minimal technical conditions to be met by solar thermal installations. It regulates the use of these technologies, also serving as a guideline for all users, with a main focus on durability, reliability and security requirements.

Owing to the significant potential that the country is offering, New Zealand’s Solar Industry association tries to promote the use of solar technologies in different sectors. The presentation comprises an outline of the available solar technologies – passive, photovoltaic and solar thermal – and gives a more in-depth description of the latter given its multiple advantages and spread within the country.

This position paper is a deliverable of the Task 38 “Solar Air-Conditioning and Refrigeration” of the IEA Solar Heating & Cooling Programme. It describes the application of active solar heating and cooling technologies within the heating, ventilation and air-conditioning (HVAC) system of buildings in the context of increasing energy efficiency requirements.

The New Zealand Energy Efficiency and Conservation Authority (EECA) and Building Research commissioned BRANZ to undertake an independent research study on the quality of solar water heaters in New Zealand, in terms of installation quality, energy performance and durability.

Conclusions of the study point out that in terms of quality, the systems analysed are very diverse, which denotes that there is still some issues in the application of standard practices.
