Environmental Approach for Energy Audits on Government Buildings: A Mexican Case for the Air Conditioning System

Journal of Environmental Protection 2018年第3期9卷 278-293页

作者： Luis E. Velazquez Rafael Perez-Rios Nora E. Munguia David S. Zepeda Carla Neudert Javier Esquer sustainability Graduate Program Industrial Engineering Department University of Sonora Hermosillo Mexico freelance sustainability consultant Hermosillo Mexico

In the face of the climate change, energy consumption is one of the main issues to be solved. Energy audits are useful tools that may contribute to develop energy efficiency initiatives. The purpose of this paper is to provide insights into how energy audits, with a scope on air conditioning (AC) systems, contribute to develop energy efficiency options for a government building in the city of Hermosillo, Mexico. The methodology is based in the energy audit framework proposed by the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE). Results show that, in a typical day of maximum consumption, AC represents 64% of the total electrical consumption, while office equipment accounted for 22%, and lighting 14%. Additionally, AC system has a yearly consumption of 54,419.40 kWh with an emission estimate of 24.92 tons of CO2-eq/year. Three approaches for energy efficiency proposals were addressed through AC systems: Improvement of the operation and consumption habits, maintenance and reconditioning of facilities, and replacement of AC units. While Mexico has international commitments through environmental treaties related to contribute to climate change mitigation, this study shows that, at least one government building still produces potential impacts that can be deterred by addressing structural and behavioral changes related to AC operation. Finally, this study may be used as reference for energy efficiency practitioners or decision-making authorities in the public administration field for developing better energy policies for government buildings.

Journal of Geoscience and Environment Protection 2015年第9期3卷 57-73页

作者： Bashir A. El Tahir Akshay Vishwanath freelance consultant Agroforestry and Ecosystems Analysis El Obeid Sudan People and Landscapes Programme Eastern and Southern Africa Regional Office (ESARO) International Union for Conservation of Nature (IUCN) Nairobi Kenya

The objectives of the present study were: 1) to identify the prioritized marketable natural products (NPs) from agroforestry systems (AFS), and 2) to conduct market value chain analyses of the most important and prioritized NPs to identify markets and marketing channels;actors, functions and characteristics;constraints and opportunities to entry and growth;opportunities for value addition, and conduct analysis of strengths, weaknesses, opportunities and threats (SWOT analysis). The study was conducted in the Refugees’ camps and their hosting communities in Eastern Sudan. Using the participatory value chain analysis (PVCA) approach, it was found that communities in the project sites obtained a multiplicity of NPs for sustenance and for increasing their incomes. Eight products were identified and ranked as the most important NPs with greatest opportunities for enterprise development at the community level. These are: gum Arabic, honey, fodder, non-timber forest products (NTFPs) and tree seeds. Gum Arabic has been shown to score higher ranks in terms of a) marketability b) ecological suitability (availability), c) social suitability, and d) potential for value addition. The results show that marketing of gum Arabic in the study site is characterized by a large number of producers and relatively few traders and companies work through seven marketing channels. The results demonstrate that in the customary marketing channel there is an upward skewed benefit distribution among the value chain actors. The total relative commercialization margin was 80% indicating that “traders” accrued higher proportion, while “producers”, receive less income (20%) of the end market price. Poor land security, one-sided prices, taxes and levies, lack of finance and appropriate skills are major impediments to gum commodity growth and development. One of the most important opportunities for growth and entry of Gum Arabic are: it is natural organic product and thus well-fit for fair trade, envi

Estimation of Economic Value of Agroforestry Systems at the Local Scale in Eastern Sudan

引用

Journal of Geoscience and Environment Protection 2015年第9期3卷 38-56页

作者： Bashir Awad El Tahir Akshay Vishwanath freelance consultant Agroforestry and Ecosystems Analysis El Obeid Sudan People and Landscapes Programme Eastern and Southern Africa Regional Office (ESARO) International Union for Conservation of Nature (IUCN) Nairobi Kenya

The objective of this paper is to institute farmers’ own perceptions of the on-and off-farm benefits of agroforestry systems (AFS). Using use value approach, this paper presents empirical evidence on the use values of three types of AFS practiced by the refugees and their hosting communities in Eastern Sudan. The total economic value (TEV) was applied as a framework to estimate the ecosystem values of AFS under study. Goods values were estimated using specific market values, while the services values were qualitatively described according to local perceived values of the local communities. Perceived TEV of AFS includes marketable and non-marketable goods and services. The main direct marketable and sustainable high value products include: food, cash crops, firewood, gum, fodder, NTFPs medicine, fodder, and honey. The valuation results reveal that AFS in the project sites have significantly contributed to the livelihoods of the local communities. Overall, the average net direct-use value of marketable products across all sites was estimated at 7,346,000.0 SDG (1,335,636.36 US$) HH/annum. Gum Arabic alone accounted for 38%, followed by sorghum grain and fodder 35%, and cash crops (sesame) 18%. This value would be many time higher if other indirect values (non-marketable) services such as shade, aesthetic and recreation, environmental protection, biodiversity and carbon sequestration are quantified. The goods and services mentioned above provide sustainable income to the farmer directly and viable benefits to the region indirectly. Hence, AFS in the study sites shows the way to reconcile two conflicting goals: short-term food and livelihood needs with long-term environmental conservation and improvement. The study provides evidence that the high local perceived values of AFS in the study sites constitute a central means of livelihood, whereas its contribution to the local economy. The study stresses the need to quantify the monetary values of non-marketed products to c

American Journal of Climate Change 2017年第4期6卷 597-606页

作者： Vladimir Kendrovski Franziska Matthies Goran Cerkez Maja Dragosavac Dragana Dimitrijevic Milan Rancic Elizabet Paunovic Oliver Schmoll Bettina Menne WHO Regional Office for Europe European Centre for Environment and Health Bonn Germany freelance consultant Feldafing Germany Federal Ministry of Health Sarajevo Bosnia and Herzegovina Croatian Institute of Emergency Medicine Zagreb Croatia Institute of Public Health of Serbia Belgrade Serbia

Floods have always had and will continue to have significant consequences for society. In May 2014, there was widespread flooding in the Balkans affecting Bosnia and Herzegovina, Croatia and Serbia. The aim of this article is to show that resilient and proactive health systems that anticipate needs and challenges are more likely to reduce risks and respond effectively during emergencies, saving lives and alleviating human suffering. The method draws on multiple sources of information, including a Balkan case study questionnaire survey with public health professionals involved in response to floods (n = 18) from three affected countries, and focus group discussion results (n = 43) presented at the meeting on “Prevention, preparedness and response to reduce or avoid health effects of flood events”, held in Bonn, Germany, in October 2015. The proposed range of measures to protect population health, organized around flood prevention, preparedness, response and recovery listed issues and considerations largely corresponds to the identified needs by Member State requests, following the Balkan country experiences. The consideration of lessons for early warning, preparedness and response and the integration of research results would lead to improved preparedness measures to better prevent flooding risks. Experiences in the WHO European Region point to a need to shift the emphasis from disaster response to long-term risk management.

Lumbar Stenosis of the Aging Spine: Evaluation and Treatment According to the Evidence Based Medicine for the Improvement of the Quality of Life

引用

Open Journal of Therapy and Rehabilitation 2017年第1期5卷 36-42页

作者： Luca Collebrusco Luca Palmieri Giovanna Censi Rita Lombardini Research Department C.R.O.M.O.N.

The lumbar spinal stenosis (LSS) is a syndrome with a wide economic and social impact on the adult population. It is a particular form of narrowing of the lumbar vertebral canal or the intervertebral foramina which can compress the neural and vascular elements in the lumbar spine. It is a degenerative process which predominantly affects the geriatric population. The increase of the life expectancy has increased the health needs of this target of population. The (LSS) is a syndrome that can manifest itself with lower back pain and pain to the inferior limbs, and functional disabilities which affects mobility and motor skills. Given the complexity of the clinical presentation, an accurate clinical-functional evaluation is needed that includes: The combination of clinical signs from the patient’s history, a physical evaluation and diagnostic imaging, excluding possible red flags. In this respect, the use of Rehabilitative Ultrasound Imaging (RUSI) might be useful in the evaluation and treatment process, enhancing the effectiveness and documenting the benefits of it. The aim of this work is to propose an integrated evidence-based approach that may be useful for improving the quality of life of LSS patients.
