New standard to improve energy performance of historic buildings

Ensuring the preservation of a building’s historical appearance while raising its energy efficiency is not necessarily a contradiction. A new standard named EN 16883:2017, Conservation of cultural heritage, provides a set of guidelines to improve the energy performance of historically significant structures. Researchers working for the IEA Solar Heating and Cooling Programme are now looking for case studies to evaluate processes and assessments proposed in the standard.

Hidden under its natural slate roof, there is a state-of-the art solar thermal system, including 44 m² of roll-bonded Thermoslate absorbers installed in the space between wooden trusses and natural slates.

Slim all-black collectors: the next generation
by Bärbel Epp

Dutch-based HRsolar began manufacturing a redesigned collector on a fully automated production line. Called Nero, the black-coloured unit is 40 mm thick – as slim as a PV panel. According to the manufacturer, the aim had been to “reinvent the concept of solar thermal, since it is increasingly being integrated with PV systems and heat pumps.”

Solar heat in 10 hospitals
by Marisol Oropeza

Mexico City has invested MXN 14.7 million – about EUR 672,000 – in bringing solar water heating to 10 public hospitals. The aim is to reduce fuel consumption by 35 % and to save 446 tonnes of carbon dioxide equivalent. After six months, the systems totalling 1,176 m² of collector area have already contributed over 50 % to the estimated emission savings.

ESCO model grows in popularity in South Africa
by Bärbel Epp

“Our clients are cash flow positive from day one,” South African company Energy Partners claims on its website. Up until now, it has been offering heat and steam purchase agreements, mainly on coal boilers. “Purchase contracts for solar heat in combination with fossil fuel boilers could be part of our portfolio in the future,” Johan Kritzinger, Head of the Steam division at Energy Partners, said after participating in a policy workshop organised by Solar Payback in July.
