Summary

Energy Audit of Building Systems: An Engineering Approach, Second EditionBuildings account for almost half of total primary energy use and related greenhouse emissions worldwide. Although current energy systems are improving, they still fall disappointingly short of meeting acceptable limits for efficiency.

Well-trained energy auditors are essential to the success of building energy efficiency programs—and Energy Audit of Building Systems: An Engineering Approach, Second Edition updates a bestselling guide to helping them improve their craft. This book outlines a systematic, proven strategy to employ analysis methods to assess the effectiveness of a wide range of technologies and techniques that can save energy and reduce operating costs in residential and commercial buildings.

Useful to auditors, managers, and students of energy systems, material is organized into 17 self-contained chapters, each detailing a specific building subsystem or energy efficiency technology. Rooted in established engineering principles, this volume:

  • Explores state-of-the-art techniques and technologies to reduce energy consumption in buildings
  • Lays out innovative energy efficiency technologies and strategies, as well as more established methods, to estimate energy savings from conservation measures
  • Provides several calculation examples to outline applications of methods

To help readers execute and optimize real building energy audits, the author presents several case studies of existing detailed energy audit reports. These include results from field testing, building energy simulation, and retrofit analysis of existing buildings, with recommendations based on sound economic analysis. Examining various subsystems, such as lighting, heating, and cooling systems, it provides an overview of basic engineering methods used to verify and measure actual energy savings attributed to energy efficiency projects. The author presents simplified calculation methods to evaluate their effectiveness and ultimately improve on them. Ideal either as a professional reference or a text for continuing education courses, this book fortifies readers’ understanding of building energy systems, paving the way for future breakthroughs.

What Does Greek Crisis Mean for Azerbaijan’s Energy Interests?

greek-crisis-2The near collapse of Greece’s economy has raised pressing questions for energy power Azerbaijan, which had viewed the country as a potential turbo boost for its energy ambitions in the European Union. Now, as Athens cleans house financially and talks deeper energy ties with Russia, Azerbaijan, which has an agreement to purchase a majority share in Greece’s gas distribution network, needs to protect its own interests, energy analysts say.
 
Azerbaijan’s entry point into Greece comes via the Trans-Adriatic Pipeline (TAP), an 870-kilometer-long gas pipeline which, by around 2019, will bring Greece, Albania and Italy 10 billion cubic meters of Azerbaijani gas per year – part of a 3,500-kilometer-plus-long pipeline network from the Caspian Sea called the Southern Gas Corridor.
 
In 2013, the State Oil Company of the Azerbaijani Republic (SOCAR) further strengthened its European targets by agreeing to pay 400 million euros (then $524.2 million) for a 66-percent stake in Greece’s state-owned gas distribution network, DESFA, its first such European acquisition. Via DESFA, which will operate the Greek section of the TAP pipeline, SOCAR also would obtain half ownership in a planned 182-kilometer-long branch to Bulgaria.
 
But Greece, since the beginning of 2015, has indicated that it wants to reduce SOCAR’s share of the network to 49 percent. And that it wants cheaper prices for the 1 bcm of gas it will receive annually from TAP.
 
SOCAR has resisted both requests, but, now, with a question mark over all of Greece’s assets, much less its ability to pay for gas, Baku may need to change its expectations.
 
“Greece’s huge debts stand to jeopardize the Southern Gas Corridor and Azerbaijan being a major shareholder in DESFA,” commented Mehmet Öğütçü, chairperson of the Istanbul-based Bosphorus Energy Club, a networking group of which SOCAR is a member.
 
For one, further delay on SOCAR’s acquisition of DESFA is likely. Under the terms of Greece’s bailout deal with the EU, a newly created fund may obtain control over Greece’s gas grid and the national gas company DEPA, but not until after October, Hellenic Shipping News reported on July 27.
 
One energy executive quoted by the publication, Aegean Gas Chief Executive Officer Theodore Theodoropoulos, said that, consequently, he does not think SOCAR’s purchase of DESFA “will proceed in its current form.”
 
At the same time, Baku’s own enthusiasm for DESFA may be growing cold.
 
Thanks to lower oil prices, SOCAR and Azerbaijan both have seen their revenue shrink. Furthermore, in January, the European Commission suspended deliberations about whether to approve SOCAR’s purchase of DESFA.
 
Reasons for the delay are not clear – some sources say the EU, others SOCAR – but energy expert Marco Giuli of Brussels’ European Policy Center, an independent think-tank, believes Russia inadvertently plays a role here.
 
EU legislation bars Russia’s Gazprom, the source of most of Greece’s gas imports and SOCAR’s distant rival in the campaign for European markets, from taking over DESFA. Gazprom in 2013 withdrew from a bid for DESFA’s parent company, DEPA.
 
“This is a matter of credibility. The EU does not want to be seen as allowing SOCAR to get what Gazprom couldn’t get,” Giuli said.
 
SOCAR, by contrast, holds only a 20-percent stake in TAP, a six-partner project which is exempt from EU rules requiring third-party access to pipelines.
 
SOCAR has not commented publicly on DESFA since the EU’s July 13 bailout deal with Greece, but on July 19, Azernews.az, an Azerbaijani-government mouthpiece, underlined that SOCAR’s takeover of the network would inject much needed cash into the Greek economy.
 
The original June 2013 purchase deal, however, allows SOCAR to opt out of DESFA if the sale is not concluded within two years, Greek and Azerbaijani media outlets have reported.
 
Yet even if the DESFA deal falls through, analysts believe that Greece and Azerbaijan will remain energy partners.
 
If Greece opts out of the TAP pipeline, it will incur penalties. “So, it concerns Europe, rather than Baku,” noted Ilham Shaban, director of the Baku-based Caspian Barrel, an energy research center.
 
Shaban, however, sees no risk for such a prospect. Greece needs to promote its own energy security. “Athens will hang on to Azerbaijan so that it chooses Greece for its resources to flow into central Europe,” he predicted.
 
For Greece, the construction contracts, thousands of jobs and related investment from the TAP pipeline are “godsent gifts,” agreed Öğütçü.
 
Greece earlier had expressed interest in also taking a share in TAP, and in receiving annual transit fees. Azerbaijan welcomed the first proposal and rejected the second.
 
But, at the same time, Greece, led by the left-wing Syriza Party, also is quite happy to hold on to Russia, the source of most of its gas and oil imports.
 
On July 12, as Greece debated the EU bailout deal, Russia, which signed an agreement in June with Athens to run its proposed 47-bcm Turkish Stream gas pipeline across Greece, pledged to consider “direct energy supplies” to Greece.
 
Details have not emerged, though Moscow recently reemphasized its commitment to the pipeline agreement.
 
Energy analyst Giuli, citing EU legislation, plays down the prospect of such a partnership, however. “One can, of course, speculate about Greece looking for Russian financial support, but, in the end, Greece cannot commit exclusively to one single source [of gas]…”
 
The EU, meanwhile, recently underlined its support for Azerbaijan’s energy ties to Europe. “Azerbaijan is our reliable and strategic partner in the energy field, and we want to take this partnership further,” European Council President Donald Tusk said in Baku on July 22.
 
Nonetheless, Azerbaijan still feels the need to downplay Turkish Stream.
 
Writing on July 24, Azernews.az noted that Russia will need “many years” to find the funds for the $50-$60-billion pipeline. By contrast, it boasted, Azerbaijani gas from TAP would be “finding clients long before … Russian gas arrives…”

Italy grants Albania 16.5 mln euros to empower energy system

Duke-Energy-Power-Lines-5-720x288TIRANA, July 23 – The Albanian ministry of energy and industry and the Italian government represented by the Italian ambassador to Tirana Massimo Gaiani signed on Thursday a 16.5 million euro (about 18.2 million U.S. dollars) agreement on behalf of a “Memorandum of Cooperation” for the energy sector.

The grant comes as the last part of this memorandum reached between the two governments last year. The agreement was signed by Albanian minister of energy and industry Damian Gjiknuri and the Italian ambassador to Tirana, Massimo Gaiani while present in the ceremony were also the chairmen of Albanian Transmission System Operator (OST) and Albanian Operator of Electricity Distribution (OSHEE).

This grant will be invested in the transmission and distribution system of the electrical energy while it aims the increase of efficiency in this sector and conclusion within the deadline of the new dispatcher center of OST.

The Albanian minister of energy and industry stressed the importance of the support from the Italian government in the implementation of several projects in the electrical energy sector in the country.

“We will invest in Himara and Saranda cities in the transmission and distribution systems, in order to improve the network in these touristic areas,” the minister was quoted by Albanian daily news as saying.

On his part, Gaiani declared that “With this grant we enclose projects which we started several years ago, at a total worth of 93 million euros.”

This grant will empower the energy potential in Albanian southern areas and will expand the data control system in all substations 110 KV.

“These two projects will make the electrical energy system more reliable and integrated with the European one,” the Italian ambassador said.

He added that this financing represents the completion of the technical aspects for the projects that will be realized by Italian embassy, ministry of energy and industry, OST and OSHEE. (1 euro = 1.10 U.S. dollars)

Shell bids to drill two Albanian onshore blocks

shell albaniaA venture between Royal Dutch Shell and Canada’s Petromanas has applied to drill two onshore blocks in central Albania close to another promising well they are drilling further south, an official said on Thursday.

The official said three bids had been submitted for the blocks – from Shell Upstream Albania B.V with Petromanas Albania GmbH, Israel’s Delek Group Limited and Interland Investments SA.

The National Resources Agency has forwarded the bids to the Energy Ministry, which will pick a winner and instruct the agency to start negotiations.

Shell’s bid signals renewed interest in Albania, a NATO nation seeking to join the European Union, after many oil majors failed to strike oil there in the decade after it toppled communism in 1990.

The Shell-Petromanas venture in Albania is now drilling two wells to size up the output potential after very promising initial results at their Shpirag well, half a mile from the spot where Occidental found very little oil in 2001 and quit.

Croatia – Expect Oil & Gas Developments Soon

Croatia - Expect Oil & Gas Developments SoonGlobal Summits organiser, IRN is delighted to announce that the 4th Balkans Oil & Gas Summit will be held in Dubrovnik, Croatia.

This year’s event, originally to be held in Athens, Greece, will now be hosted in Dubrovnik, Croatia with the full support of the Croatian Ministry of Economy and the Croatian Hydrocarbon Agency to bring to the Summit’s delegation a highly valuable Balkans Summit on 23rd-25th September 2015.

The 4th Balkans Oil & Gas Summit will also be held under the endorsement of the Ministry of Energy and Industry of Albania, the Ministry of Economy of Montenegro and the Federal Ministry of Energy, Mining and Industry of Bosnia-Herzegovina with Government Officials joining from all over the Balkans region.

Croatia has been attending and supporting the senior level meeting since its origination in 2012. Here’s what Alen Leveric, Deputy Minister of Economy said about the Balkans Oil & Gas Summit;
“Since 2012, we had the unique opportunity to annually report and promote all development stages of one of the most important Croatian strategic projects – exploration and exploitation of hydrocarbons (onshore and offshore).
In June 2015, Croatian government published that three companies (Vermilion Zagreb Exploration, INA and Oando PLC) will share six licences to explore for oil and gas in Croatia’s northern Drava river basin and in the east of the country.
In January 2015, Croatia awarded 10 offshore oil and gas exploration licences for drilling in the Adriatic. Seven licences went to a consortium of Marathon Oil and OMV, two to INA and one to a consortium of ENI and Medoilgas.
With this in mind, Croatia is definitely on their way of becoming an energy leader in the south-eastern Europe.” Alen Leveric, Deputy Minister, Ministry of Economy, Croatia

Many international and national oil companies have already confirmed their participation in the Summit with the organisers expecting the attendance of 200 senior level executives.
