India: New Energy Building Regulations to Boost Solar Heating Market

Submitted by Baerbel Epp on July 24, 2017
Jaideep MalaviyaThis June, the Indian Ministry of Power published an updated version of the Energy Conservation Building Code (ECBC) developed by the Indian Bureau of Energy Efficiency (BEE). The ECBC has established energy efficiency standards and a solar share of hot water demand for newbuilds and refurbished homes and commercial buildings across India. But it will be the task of municipal corporations to issue notifications which mandate compliance with ECBC 2017 regulations in the construction sector in their area. The ECBC was launched in 2007 based on the Energy Conservation Act from 2001. The photo shows a vacuum tube installation for solar process heat at automotive manufacturer JBM Group. Solar industry stakeholders have said that it was regrettable that industrial buildings and applications are not covered by the ECBC 2017.

Italy: Market Decline Continues Despite Appealing Incentives

Submitted by Baerbel Epp on February 1, 2017
Italy InstallationItaly’s solar thermal market experienced another 10 % drop in 2016 despite the availability of at least two appealing incentive schemes: a 65 % tax reduction for small systems and Conto Termico 2.0, a revised national support scheme in place since the beginning of 2016 to support plants of up to 2,500 m². To find out more about the primary reasons for the continuing decline of the national market, solarthermalworld.org spoke with Federico Musazzi, Secretary General of Assotermica, the Italian Association of Manufacturers of Equipment and Components for Heating Systems, and official at the umbrella organisation ANIMA, the Federation of Italian Associations in the Mechanical and Engineering Industries.

Uruguay: The Battle for Market Growth Continues

Submitted by Baerbel Epp on September 23, 2015
Uruguay market developmentUruguay, whose population of 3.4 million makes it one of the smallest countries in Latin America, has shown positive market development since 2007. Cumulated installed solar thermal power saw a notable increase from 1 to 9.5 kWth per 1,000 inhabitants. According to numbers published by the National Energy Department and the annual national energy report, the country’s total collector area installed by the end of 2014 amounted to 46,241 m². Mesa Solar, the multi-sector network for the promotion of solar energy in Uruguay calls for accelerated growth to achieve 1 million m² in 2020. The official target of the government is 150,000 m² until 2024.

Italy: 903 Municipalities with Solar Thermal Building Obligation

Submitted by Baerbel Epp on September 2, 2015
Italien MapIn Italy, a recent national decree no. 164/2014, the so-called Sblocca Italia, aiming at simplifying bureaucratic processes, introduced the concept of a standard building code, which should be developed by the government in cooperation with the regions and municipalities. Of course, in such a standard code, the provisions on energy efficiency and renewables will play a relevant role, which will once again ignite the debate on this hot issue. Hence, Legambiente, one of the major environmental associations in Italy, titled its annual study about the status quo of the implementation of the national renewable building code Simplification and Innovation in Construction: Towards the Building Regulations Act. According to this study, which was presented in February this year, 903 Italian municipalities introduced a mandatory regulation to cover a share of sanitary hot water demand, usually 50 %, with solar thermal technology (see the attached document). The map shows the regions with these kinds of mandatory regulations in place (red and green), as well as the regions without renewable building obligations (orange and yellow). Sicily introduced no specific building regulation.

Lebanon: Municipalities of Tyre Discuss Solar Obligation Pilot Project

Submitted by Baerbel Epp on May 28, 2015
Lebanon workshopThe Lebanese Center for Energy Conservation (LCEC) has organised a consultation meeting with the Union of Tyre Municipalities (UOTM) to discuss the implementation of a solar ordinance in the south of Lebanon. The workshop took place in the Platinum Hotel in the city of Tyre on 9 May under the patronage of Abdel Mohsen El Husseini, President of the UOTM. This consultation meeting was a follow-up to a series of bilateral talks with individual municipalities to introduce and promote the implementation of a solar obligation at municipality level. With its 60 municipalities, the UOTM is committed to adopting a solar obligation in the framework of a pilot project.

New Report: Lessons Learned from 20 Non-Residential Building Renovations

Submitted by Pam Murphy on May 14, 2015

Buildings are responsible for up to 35 % of the total energy consumption in many  IEA countries. Exemplary non-residential renovation projects are showing that total primary energy consumption can be drastically reduced together with improvements of the indoor climate.  This IEA SHC report highlights 20 of these renovation projects. The projects are also described in detail in a series of eight-page brochures available for download from http://task47.iea-shc.org/publications.

National Building Regulation in South Africa

Submitted by Baerbel Epp on February 1, 2015
Since September 2014 the extended South African National Standard SANS10400 XA is in force that stipulates that a minimum volume fraction of 50 % of the annual average heating requirement for hot water shall be provided by means other than electric resistance heating or fossil fuels. The regulation applies to all new buildings with hot water consumption, as well as refurbished ones if the refurbishment requires planning approval from a local authority. For further details read news.

South Africa: Building Regulation Not Applied as Intended

Submitted by Baerbel Epp on February 1, 2015
SOLTRAIN stakeholder meetingExtended South African National Standard SANS10400 XA, Energy Usage in Buildings, is the big hope of the country’s solar thermal system suppliers. Part XA 2, which was added to SANS 10400 in September 2011, reads: "A minimum volume fraction of 50 % of the annual average heating requirement for hot water shall be provided by means other than electric resistance heating or fossil fuels.” The regulation applies to all new buildings with hot water consumption, as well as refurbished ones if the refurbishment requires planning approval from a local authority (for more details, see the attached architectural guide). After a transition period and a broad discussion among those affected by the new regulation, XA officially became law on 9 September 2014. The photo shows one of the stakeholder meetings within SOLTRAIN, the Southern African Solar Thermal Training and Demonstration Initiative.

Hawaii: Results of Three Years of Solar Obligation

Submitted by Baerbel Epp on September 3, 2013

Since Act 204 “mandating” solar water heating systems on all new single-family dwellings came into force in January 2010, the number of new residential houses equipped with a solar water heater has risen to 75 % in Hawaii. This is the conclusion from the statistics published by Hawaiian distributor Inter-Island Solar Supply (IISS). Before the mandate, only 40 % of the new residential homes in Hawaii had solar water heaters, estimates Ron Richmond. The Business Development Manager of IISS and former member of the Board of the Hawaii Solar Energy Association (HSEA), however, thinks that there is still room for improvement: The new houses require no independent third-party inspection, because homeowners do not receive any funding from local utilities.

Uruguay: Growing at Its Own Pace

Submitted by Baerbel Epp on July 15, 2013

Uruguay’s government aims at reaching a renewable share of 50% in its national energy mix by 2015. In order to achieve this target, the government approved the so-called Solar Plan in March 2012. It offers up to USD 800 per solar thermal system to clients of the main public utility UTE. UTE reduces the energy bill of any SWH purchaser Uruguayan Peso (UYU) 700 over the first 24 months (UYU 16,800 = USD 800). In addition, the new Decreto No 451/011 mandates a 50 % solar share for hot water generation in hospitals, hotels and sports clubs – for both newly built and soon-to-be-renovated houses. However, some industry actors did not see a dramatic growth in solar thermal installations. Despite a lack of official statistics, one figure is clear: The subsidy scheme offers a budget for 2,000 systems, out of which 600 were already completed between March 2012 and July 2013.
