The shortage of affordable and healthy housing is nothing new for communities across the South, but trends in gentrification and infill building, the redevelopment of urban spaces as new construction, have exacerbated these shortages in many cities and towns in Georgia.Jermaine Durham, the new housing and community development specialist with University of Georgia Cooperative Extension and assistant professor of housing and community development in the UGA College of Family and Consumer Sciences (FACS), grew up in Georgia watching these trends impact his hometown of Hartwell and his adopted hometown of Savannah.He’s spent his career working with families to build stronger, more stable communities around the state. He joined UGA Extension and FACS this spring to study the housing problems Georgians face and to help find answers.Durham plans to focus on developing partnerships with housing groups around Georgia and working with county Extension agents to increase the amount of housing programming they offer in their communities. He also serves as director for the Georgia Initiative for Community Housing, which partners with the Georgia Department of Community Affairs, Georgia Power and the Georgia Municipal Association.“Extension agents on the ground have to be pretty flexible,” Durham said. “They may be focused on nutrition but find out, ‘Hey we have this huge housing problem.’ I want to help them be ready to tackle a wide range of issues pertaining to housing.”Durham says UGA Extension plays a prominent role in outreach and working with communities on local issues. As UGA’s sole community development Extension specialist, he feels responsible for helping spread awareness through his knowledge on the issues that many Georgians face.“In urbanized areas, we see that affordability is the preeminent issue where there’s not enough housing for the lower income groups, and this oftentimes has a racial component to it as well,” Durham said. “In some of the more rural areas, we see a combination of housing affordability issues and a growing epidemic of blighted homes.”Housing affordability in rural areas is tied directly to the declining stock of houses, while in urban areas, more investment and development lead to gentrification and the outpricing of lower-income residents, Durham said.Durham started his career in community development early as a youth program manager at Goodwill of the Coastal Empire, working on workforce development and mentoring. He also worked as a microbusiness coordinator at Savannah State University and with the Housing Authority of Savannah before returning to school at Clemson University, where he will receive his doctorate in planning, design and the built environment this spring. His research focuses on the foreclosure crisis in the South and race and economic inequality and their impact on neighborhoods and communities.Durham is eager to put what he has learned to work in the Extension setting and expand on his research into Southern communities.Next fall and spring he will begin teaching courses in subsidized housing and housing and community development at FACS.“UGA has always been a force in the community, so it’s great to be a part of the UGA family in this capacity,” he said.
Removable Basement FloorsWalls, Roof, and an ElevatorDesigning a High-Performance Home A closet flange becomes a sturdy base for this heat exchanger. Unions will allow the heat exchanger to be disconnected an checked periodically.InstallationYou can see there is a lot of copper in these things. The one we installed was a good 60 lb. We came up with a simple way to mount the item effectively. We used a 4-inch water closet flange. We removed the small groove inside this flange so the 4-inch ABS pipe could be passed right through. This is basically creating a bulkhead fitting on your pipe, but there is no break in the pipe. Glue it on with solvent, and then mount it to a couple of wood runners, which make good supports. Notice also we’ve installed unions around the exchanger. This will let us more easily check its insides from time to time and clear out any build-up. Drainwater heat recovery is a simple way of capturing some of the energy in hot water that’s headed down the drain — energy that ordinarily is thrown away.Here are a few points to consider:The cost is $500 to $1,200. Installation is extra.Go with the largest diameter and longest exchanger you can fit into your plumbing, assuming a vertical installation. There are horizontal units available from Ecodrainalthough I believe they are available in just one size. Leave at least a 12-inch run of straight drain pipe above the exchanger to smooth out the flow. (You can see we’ve done this from the photos. We’ve used 4-inch pipe.)It is still worthwhile to pump shower drains in the basement back up so they can drain into the heat exchanger. The cost of these Gulper pumps with a kind of control that senses the water level in the drain is something like $300.Gather all your drains to one place, if possible. In our case, we’ve done this with all the shower drains in the house, which all happen to be clustered together in the building.Savings of about 20% or more on water heating energy is possible, depending on how things are plumbed in the house.Hot water recovery times can be dramatically improved. This, to me, is a very sure sign of energy being saved.The design requires a double-walled heat exchanger. In other words, there must be a (tiny) air space between the copper pipe carrying the drain water, and the copper pipe carrying the potable water — this severely limits the efficiency of the unit, and increases the costs (more on this later).Surface tension effects cause the drain water to stick to the drain walls in a thin film. This is why heat exchange is arranged at the surface of the drain pipe.Simple payback periods range from two years to 10 years.

BLOGS BY LYNDON THAN Efficiency could be improved with another designThe best units are limited to something like 60% efficiency, measured in terms of inlet and outlet water temperatures. Industrial heat exchangers are good for over 90%, even over 95% in some cases. A much more effective design would be to have a copper drain pipe inside of a larger, plastic pipe filled with pressurized, cold water. This would increase heat exchange efficiencies a lot (to probably above 80%, easily more), and reduce the cost of the units greatly as well. It would also reduce the pressure drop incurred by the units we use today.Given the huge potential for energy saving across a nation like Canada, one would think it is possibly worth the very small contamination risk. After all, if ever there were a leak, the pressurized water would go into the drain, not the other way around, and it would be fairly easy to detect: just check the water meter while all fixtures are turned off. Perhaps an annual check would be worthwhile.Imagine if we could recover 95% of the energy used to heat hot water for bathing. Small electric point-of-use hot water heaters would be so much more viable; they could be built right in to shower fixtures, and this could lead to all sorts of interesting plumbing configurations (just plumb one line, for example — no need for both hot and cold?). Water pressure lossesSomething not mentioned very often: What about the pressure losses? The unit we chose to install uses a single 3/4-inch copper tube (about 60 feet of it) wrapped around the 4-inch drain. In choosing a product, it is a matter of heat exchange performance and this is measured by the Canadian government testing apparatus. After finding units that perform well, we looked for designs that retain the most water pressure.So, how to plumb in order to retain water pressure? If you have high water pressure, this may not be an issue, but keep in mind, water pressure is not free. Someone, somewhere, must provide it, and I feel we must always think of our buildings as off-grid, so we want to minimize energy losses at every opportunity. Therefore, buy a unit that performs just as well, but results in the least pressure loss. Then, I would plumb everything through it. After all, we heat a lot of water to just room temperature via space heating — it sits there in the toilet, in the pipes, etc. But to recover that heat using the drainwater heat exchanger, the cold side must flow. Therefore, as per manufacturer recommendations, just plumb everything through it. I would still provide a small line to a drinking water fountain or ice maker, however. An alternate strategyOne way around this is to avoid the issue altogether. Instead of directing reclaimed heat to the domestic hot water system, transfer it to the space heating system instead, i.e. to a non-potable heat sink, such as a hydronic heating component, or directly to refrigerant in a heat-pump system. This avoids the water contamination issue, and can recover much closer to 100% of the energy used for heating water. Sadly, I know of nothing on the market that does this as yet, but it would be very easy to build something. A coaxial pipe heat exchanger is all you would need.Another approach involves using an auxiliary tank and a pump. We recover heat even from processes like clothes-washing and dish-washing, in which the hot drain water is not expelled at the same time cold water is being drawn in. Why not just leave the water in the tub?One comment I’ve read is this: Recover your hot water heat simply by leaving the shower water in the bathtub and letting it cool to room temperature before allowing it to drain away. This is an excellent measure, and no cost to install, but it has some issues. First, it adds moisture to the house — good in winter, probably, not so good in summer. Second, it’s only possible with bathtubs because showers can’t hold much water. Third, consider the ring around the tub. Fourth, it gets difficult to have multiple showers in a short period of time, such as on busy mornings with a family of four.And fifth, don’t assume it is 100% heat recovery. The water in the tub cools only to room temperature, which is almost the halfway-point from the cold water inlet temperature to the 40°C (104°F) or so needed for a shower or bath. So, heat recovery is something like 60%, similar to a good drainwater heat recovery installation.

zoom Bermuda-based shipowner Ship Finance International has decided to acquire a fleet of fifteen feeder-size container vessels and sell a 1,700 TEU boxship.As informed, the fifteen vessels, ranging from 1,100 TEU to 4,400 TEU, will be acquired in combination with long-term bareboat charters to an undisclosed container line.The purchase price is confidential, but close to recycling value of the vessels. The charter term will be seven years from delivery, with subsequent purchase obligations by the charterer, Ship Finance said.Delivery of the vessels is expected in April and their aggregate EBITDA contribution is estimated to be approximately USD 20 million per year, according to the company.What is more, Ship Finance International has agreed to sell the 1,700 TEU container vessel SFL Avon to an unnamed company. This vessel has been operated in the short-term charter market and net sales proceeds will be approximately USD 12.5 million.“Delivery to the new owner is expected in April 2018, and we expect a minor book gain in connection with the sale,” Ship Finance International said.“This transaction offers an attractive cash flow from a strong counterpart and with limited downside risk. The SFL Avon was our only container vessel operated in the short-term charter market, and in light of the recent upswing in values in the sector we have decided to sell the vessel as we evaluate various growth prospects,” Ole B. Hjertaker, CEO of Ship Finance Management AS, commented.“We are seeing increasing opportunities to deploy capital in 2018 and we remain focused on growing our fleet and charter backlog,” Hjertaker added.

The total cost of the planned investments is EUR 71.2 million.The current TWIN-PORT 3 project will concentrate on reducing the environmental impact of the increasing RoPax traffic and continues improving the multimodal transport link between Helsinki and Tallinn. Auto-mooring and on-shore power supply systems will be installed to the Old City Harbour in Tallinn and to the West Harbour in Helsinki to reduce noise and air pollutant in port areas.TWIN-PORT 3 project will involve the period 2018-2023. Largest investments will be made by the Port of Helsinki and the City of Helsinki, EUR 24 million and EUR 27 million respectively. The Port of Tallinn will invest EUR 16 million and the ship operators EUR 4 million in total.“The flows of traffic and passengers between the two cities have been constantly growing for a decade already. Therefore, the project is crucial for both cargo and passenger flows to ensure the smooth traffic between Helsinki and Tallinn,” Valdo Kalm, CEO of Port of Tallinn, said.The previous two TWIN-PORT projects mainly consisted of building and development of the passenger terminals in Helsinki and Tallinn, opening the Muuga-Vuosaari ro-ro line and bringing a new LNG-fueled ferry MS MEGASTAR to serve Tallinn-Helsinki line.
OTTAWA — The Liberal government’s overhaul of the patronage system has led to gender parity in government appointments, but new figures show few of those women are in leadership posts and visible minorities are being left out.Documents from the Privy Council Office show that as of last year, 55.5 per cent of appointees to federal agencies, boards and organizations were women, slightly above their proportion in the Canadian population.But the Liberals’ “merit-based” process for appointments has screened out nearly 62 per cent of visible-minority candidates as insufficiently qualified, compared to 38 per cent of applicants who are not visible minorities.Visible-minority applicants who made it past that cut and into job competitions were less likely to be recommended on so-called “advice letters” or to be appointed.According to data released to The Canadian Press under access-to-information law, the Liberals have appointed slightly more Indigenous people to government positions than their proportion of the population, but markedly fewer people with disabilities.Queen’s University politics professor Kathy Brock says that raises questions about whether there’s something in the screening process that disadvantages people with certain characteristics or from certain communities.The Canadian Press
