SA launches Open Source Centre

first_img16 January 2003The Council for Scientific and Industrial Research (CSIR) has launched an Open Source Centre to help stimulate the adoption of open source software technologies in Africa.According to the CSIR’s business unit, icomtek, open source software is very much like digital meraka – a Sotho term for common grazing land. “People may engage in private or communal productive activity o­n this land, but the land itself is kept for the common good.”Unlike most proprietary software, open source software is available at little or no cost. More importantly, the intellectual property of its inner workings – the source code – is not a closely guarded secret of any individual or organisation.The free availability of the source code encourages a model of software development, testing and modification based o­n public collaboration.icomtek specialises in information and communication technology projects which are geared to development and societal needs. The Centre plans a number of strategic interventions within the private sector, government and civil society, as well as in education and training.South Africa and Africa, icomtek argues, “will not be able to afford the investments in imported technology that are required to be a full participant in the global information society in future, if conventional approaches are followed.“Open source software has emerged as a software model that is particularly viable in the developing world, providing local software developers with access to quality code generated by international experts, allowing users to escape from the cycle of ever-increasing international licensing fees, and facilitating the development of systems that address localised needs.”The importance of open source software within the South African context is underscored by its inclusion as a component in almost every major ICT strategic proposal, such as the SA National Reseach and Development Strategy document, the bilateral Indo-SA initiative, and the proposed Advanced Institute for Information and Communications Technology.The State Information Technology Agency (SITA) has already helped the government save millions of rands by implementing open source software in the public sector.SITA spokesman Mojalefa Moseki says the government can save still more money on licensing, software procurement, support and upgrades through the use of open source software.According to Moseki, the Northern Cape provincial government is the largest user of open source software, while the Western Cape government also uses an OS-based document management solution, and bases its portal on the system’s platform.“The department of Land Affairs uses Linux and is about to implement Oracle on Linux”, Moseki says, adding: “We believe open source software is as good if not better than commercially available software. In many cases, it’s more stable and more reliable.”Open Source Centre initiatives include the following:Digital Doorway project – An initiative which explores the viability of “minimally invasive education” as an alternative means of promoting wide-scale computer literacy.Open School project – Involving the implementation of a platform to facilitate collaborative development of local educational content over the Internet, using open source principles.Culturally adaptive software – The development of systems that change their look-and-feel, context, content and language according to the culture of the person accessing the system.Open source school management system – The CSIR is part of a consortium, along with the Wits School of Computer Science, Kgatelopele Technologies and NetDay, that are working towards creating a school management system that caters for outcomes based education, and releasing it under an open source licence.The Open school initiative – Involving the implementation of a platform to facilitate collaborative development of local educational content over the Internet, using open source principles.Cultureware project – Together with South African Tourism, the Western Cape Investment and Trade Promotion Agency and the University of Fort Hare, the CSIR initiated a culture preservation project known as Cultureware, which aims to bringing cultural heritage into mainstream economic activity and commercial exploitation.Open source in government – Various proposals have been submitted to the Centre for Public Service and Innovation as part of their open source thrust in government.SouthAfrica.info reporter Want to use this article in your publication or on your website?See: Using SAinfo materiallast_img read more

Mechanical and Electrical Systems at the Orchards at Orenco Project

first_img RELATED ARTICLES Meeting the Airtightness ChallengeRoofing and Cladding for the Orenco PassivhausWalls and Windows for the Orenco PassivhausPlacing a Concrete Foundation on Rigid Foam InsulationThe Largest Passivhaus Building in the U.S.Multifamily Passivhaus Project Starts in Oregon While an ultra-high performance enclosure lies at the heart of the Passive House concept, the mechanical systems constitute the “yang” to the enclosure “yin.” The HVAC system, water heating, lighting, appliances, and conveying systems all contribute to the building’s high level of performance.Because the Orchards at Orenco project is a large multiunit residential building, these systems and components are in many ways quite different from those one would see in single-family residences designed to meet the Passive House standard. Part 1 in this blog series introduced the basic pieces of the mechanical system design at Orchards. This post will provide more information about the design and discuss some of the challenges encountered during construction and commissioning of the system. This is Part 6 of a blog series describing construction of the Orchards at Orenco project in Oregon. The first installment was titled The Largest Passivhaus Building in the U.S. A forthcoming blog will discuss the key lessons learned at the Orchards at Orenco project, and will report measured performance data from the first year of operation of the building. A hybrid approach: HVAC “pods”After reviewing the respective pros and cons of centralized vs. unitized mechanical systems, the team ultimately decided to utilize a hybrid approach, optimizing the mechanical design to capture the best qualities of those two different approaches. VentilationEach penthouse has a different size ERV, rated at 1,500 to 3,500 cfm, based on the flow rate and volume of the building zone served (see Image #4, below).The ERVs are manufactured by the Loren Cook Company. Initially the team had specified Zehnder and UltimateAir units since they were the only available units identified that met the ventilation efficiency requirement of the Passive House standard. Midway through design, however, the team identified the Cook units as potential candidates. Several months of back and forth with the PHIUS technical committee resulted in acceptance of the Cook units for our project.These units have a heat-recovery efficiency that ranges from 73% to 76%. The Cook units were considerably less expensive that the UltimateAir units which had been previously specified, and the savings allowed the owner to afford other valuable features on the project, such as the “green screen” I will discuss later.Distribution of the ventilation air from the ERVs is via 4-inch hard ducts running directly to and from each apartment. These duct “home runs” are collected into main trunk lines running above the ceiling at the third floor corridor (see Image #5, below). By keeping the duct penetrations no larger than 4 inches in diameter, this approach eliminates the need for fire-smoke dampers at each apartment (see Image #6, below).A continuous 50 cfm of supply air is delivered to each bedroom, with continuous exhaust from each bathroom and kitchen area. To filter cooking pollutants, recirculating hoods are provided above the kitchen ranges. Continuous air flow regulators installed within the ducts help to ensure balanced continuous airflow into and out of each apartment. While the mechanical design uses a centralized water heating system, a decentralized “pod” system is used to provide ventilation air as well as space heating and cooling. The project has three mechanical penthouses (see Image #2, below), each of which houses a large energy-recovery ventilator (ERV) with a heat pump condenser coil in the the supply air duct to temper the ventilation air. Each pod serves a zone of 10 to 24 apartments and adjacent common areas (see Image #3, below).The “pod” approach optimizes cost and performance while also reducing future maintenance. Regular maintenance of 57 individual ERVs would have been required if a fully unitized approach were used. Going with the pod approach allowed the use of smaller ERVs as well as shorter duct runs than would have been required with a centralized approach. Ducts were smaller, reducing system costs while also reducing distribution losses.The mechanical penthouses are built on top of the roof and accessed through large ceiling hatches at the third-floor corridors. The walls and roof of each penthouse have the same level of insulation and airtightness as the main walls and roof of the building, so the penthouses are functionally within the Passive House enclosure.center_img Water heatingTwo central boilers (Bradford White eF Series boilers with 100-gallon tanks and 98.5% thermal efficiency) provide hot water to the building. These are housed in a first-floor mechanical room near the center of the building.Over the course of multiple design iterations, the team determined that a temperature maintenance system with heat trace tape was likely to be more energy-efficient than a recirculation pump. Hot water piping to the apartments is insulated to minimize distribution heat losses (see Image #9, below). High efficiency plumbing fixtures are used at the apartments to minimize the water heating load and further improve system efficiency. Green screenThe building has an information screen mounted prominently in the main lobby (see Image #11). This screen provides news that is important to the residents, while also indicating the energy use of the overall building and the electrical usage in each apartment (see Image #12). Intended as a tool for educating the residents about their energy usage, the green screen also fosters a fair degree of social interaction. Mike Steffen is a builder, architect, and educator committed to making better buildings. He is vice president and general manager of Walsh Construction Company in Portland, Oregon. Other active systems and componentsHigh-efficiency lighting is used throughout the building to minimize the electrical load. Pinned fluorescent lighting was designed to meet a target of 0.4 Watts/square foot at the apartments. LED lighting is provided in the common areas, with lighting controls used at the corridors and stairs to further reduce loads.Upper tier Energy Star appliances were specified for the apartments (see Image #10, below). Appliance selections were made to achieve the best balance of cost and performance as well as accessibility requirements (some of which can significantly limit the number of models to choose from).Only two stairs are needed in the building to meet code egress requirements (one near each end); however, the Orchards design includes a third stairway, adjacent to the main lobby. This richly detailed stairway is intended to encourage residents to access their apartments on foot rather than using the elevator, enhancing resident health and interaction while reducing energy use even further.A MLR traction elevator is used in lieu of a hydraulic model (the type of elevator that is typically used at a building of this size). This choice, combined with the provision of the “attractive” stairway, is expected to reduce elevator-related electricity usage by 57%. Heating and coolingAt each penthouse, a Samsung AM024 VRF heat pump coil is placed inline on the supply air distribution line. This air-source heat pump has a COP of 4.31 and provides approximately 80% of the heating for the building, as well as some cooling during the summer, though it does not meet the entire cooling load. The heat pump is in parallel with the ERV so that it does not create static pressure in the ventilation system.About 80% of the heating load is met with the ventilation air. Electric-resistance cove heaters in the apartments are designed to meet the remaining heating load (see Image #7, below). These heaters are expected to operate only on the coldest of days, or in some apartments not at all. The team has metered eight of these heaters to provide verification of our assumptions.The Pacific Northwest summer is relatively cool and dry compared to much of North America, and air conditioning is usually not provided in new multifamily buildings in Oregon and Washington. Though the HVAC system at Orchards does not provide full air conditioning, the ventilation air does provide some degree of cooling.The 50 cfm requirement for supply air at the bedrooms is intended to provide additional airflow to temper the apartments during the summer months. The system includes heat-recovery bypass with an economizer to assist with night-flush cooling. The residents are instructed to close their windows in the morning, keep them closed during the day, and open them again in the evening. This helps minimize heat flow to the interior during the day during warmer periods and further assists with night-flush ventilation. Upon initial occupancy of the building, this was not well understood, but after a few hot spells, nearly all of the residents have learned the protocol.It should be noted here that two key elements of the basic building design, the balconies and the eyebrows, serve an essential shading function to keep the apartments cooler during the warmer months (see Image #8, below). Low-solar-heat-gain glazing is used at the east- and west-facing windows (LoE 366/180, argon-filled units, SHGC = 0.25) to further control against overheating.last_img read more

Innu leader named top minister as Harper unveils new cabinet

first_imgAPTN National NewsOTTAWA–Former Labrador Innu leader Peter Penashue was appointed minister of intergovernmental affairs by Prime Minister Stephen Harper who unveiled the first cabinet of his new majority government Wednesday.John Duncan kept his portfolio, but the Prime Minister’s Office changed his title to minister of Aboriginal affairs and northern development instead of Indian affairs and northern development.Concerns immediately emerged that an Aboriginal affairs minister may mean the government is looking to approach First Nations, Metis and Inuit issues as one in the same, despite each having their own distinct political, cultural and legal realities.Health Minister Leona Aglukkaq, the Conservative MP from Nunavut, also retained the Health portfolio, but gained a new responsibility as minister of Canadian northern economic development.Aglukkaq and Penashue made history, making Harper’s latest cabinet the first with two Aboriginal ministers.Penashue, who was also named as president of the Queen’s Privy Council, was the only Conservative elected in Newfoundland and Labrador in the election. He is the former head of the Labrador Innu Nation and is also the first Innu ever to be elected as an MP.Penashue has been a long time fighter for the rights of Labrador Innu and even took on the military in opposition to low level flight training in Labrador in the late 1980s and early 1990s. Penashue was also involved in shedding light on the dire situation facing the community of Davis Inlet, now Natuashish.Harper told reporters that Penashue had an “outstanding record” as an Innu leader and that he had won a “historic” election in Newfoundland and Labrador. Penashue was the first Tory elected in Labrador since 1968.He was also a key player in pushing through a major land-claim for the Labrador Innu.Joining Duncan and Aglukkaq in keeping their cabinet posts were Finance Minister Jim Flaherty and Defence Minister Peter MacKay.Former OPP commissioner Julian Fantino, who has faced criticism over the handling of the Caledonia crisis and the 2007 shut-down of Hwy 401 by Tyendinaga Mohawks, was named associate minister of defence.Public Works Minister Rona Ambrose also retained her Status of Women portfolio.Others in named to the Harper cabinet include:*Minister of Human Resources and Skills Development Diane Finely*Minister of International Cooperation Bev Oda* Foreign Affairs Minister John Baird* Treasury Board President Toney Clement* House Leader Peter Van Loan* Immigration Minister Jason Kenney*Agriculture Minister Gerry Ritz*Minister of Industry Christian Paradis*Canadian Heritage Minister James Moore*Transport Minister Denis Label*Fisheries and Oceans Minister Keith Ashfield*Environment Minister Peter Kent*Labour Minister Lisa Raitt*Revenue Minister Gail Shea*Veterans Affairs Minister Steven Blaney*Minister of International Trade Ed Fast*Minister of Natural Resources Joe Oliver*Minister of State for ACOA Bernard Valcourt*Government Whip Gordon O’Connor*Minister of State for small business Maxime Bernier*Minister of State for Foreign Affairs Diane Ablonczy*Minister of State for Western Economic Diversification*Minister of State for Transport Steven Fletcher*Minister of State for Science and Technology Gary Goodyear*Minister of State for Finance Ted Menzies*Minister of State for Democratic Reform Tim Uppal*Minister of State for Seniors Alice Wong*Minister of State for Sport Bal Gosallast_img read more
