Let’s face it. The state of home building isn’t good. Yes, we have building science and energy codes and green building programs out the wazoo. We have cool new products and home energy raters and even Joe Lstiburek. Despite all this, we still have wild ductopuses, holey air barriers, and insipid insulation installations.And I’ve finally lost my patience. I think the only way to improve the state of home building in America is to ban these things.Wait! Don’t leave yet. I know your blood may be boiling just after reading the title of this article, but please read all the way through. There’s something for everyone here. You may not like the idea of banning batt insulation, but how about blower door tests?This list is progressive. The things further down the list build on the earlier ones.Here we go:(1) Powered attic ventilators – They suck conditioned air from your house and backdraft water heaters.(2) Ventless gas fireplaces – Even the industry has a hard time justifying these things, which are already banned in Canada and other places.

Let’s use real insulation.(4) Batt insulation – It’s almost never done right.(5) Flex duct – Kinks and sags and ductopuses.

And they sometimes allow you to breathe dead possum!(10) Vented attics – Too often a place for ducts, powered attic ventilators, and dead bats.(11) Housewrap – It’s never installed well enough to be a great air barrier and installers still haven’t figured out how to flash windows with it.(12) Attached garages – If you like to breathe carbon monoxide and other toxic gases, this is a great way to add those vital nutrients to your lungs.(13) Dormers – Too hard to insulate and air seal.(14) Complex roofs – Likely to cause moisture damage.(15) Electric-resistance heat – It may be 100% efficient… but you can do better!(16) Recessed can lights – They’re a problem when they’re put in the building enclosure, especially vaulted ceilings.(17) Panned joist returns – A guaranteed way to suck in that moldy air from the crawl space… and the dead possum particles that come with it.(18) Undercut doors for return air from bedrooms – They’re just not going to let all the air get back to the main return.(19) Dryer vents terminating near air conditioner condenser units – Blowing lint into those fins is a good way to kill the efficiency of your AC.(20) High flow range hoods – You really don’t want your house to suck that bad, do you?(21) Excess wood – Less room for insulation, more thermal bridging, and it’s just a waste of money and resources.(22) Zoning that requires less than 12 units per acre – More density is better for location efficiency.(23) Unbalanced ventilation – Like that unbalanced cousin of yours, you just don’t want it in your house.(24) Thermal bridging – Would you leave cow-sized gaps in your cattle pen?(25) Airtightness higher than 1 ach50 – Air-sealing gives you the most bang for your buck in making homes energy efficient. You know this is where we’re heading, right?(26) Carpet, vinyl, and other offgassing products – “If there is a pile of manure in a space, do not try to remove the odor by ventilation. Remove the pile of manure.” Max von Pettenkofer said that in 1858, and it applies here, too.(27) 2×4 walls – Eventually all walls will have to be at least 12 inches thick.(28) Ceiling fans – People don’t turn them off when they’re out of the room anyway.(29) Manual J load calculations – Sophisticated HVAC contractors have figured out how to get rule-of-thumb results from computer programs. 96 occupants. Single-pane windows instead of low-e. Worst-case orientation. It’s easy to add load when you need to justify that oversized AC and furnace.(30) Combustion appliances – Long after our caveman ancestors discovered fire, we’re still polluting our caves with combustion products.(31) Bonus rooms – Nobody uses that room anyway. It’s too uncomfortable.(32) Attic kneewalls – One of several reasons bonus rooms are so uncomfortable. Rarely done right.(33) Energy modeling – See Manual J above.(34) Storm doors – They’re not a great investment for saving energy.(35) Thermostats – Too many people set them incorrectly anyway, sometimes at the suggestion of their helpful HVAC service company.(36) Rim and band joists insulated with anything other than spray foam – It’s just not going to work.(37) Spray foam insulation – It smells. It shrinks. Some greenie weenies don’t like it.(38) Rim and band joists – Since there’s now no way to insulate, they must be banned. Ban the band!(39) HERS ratings -Wildly imprecise. Didn’t you see my article on the Stockton study?(40) HERS raters and energy modelers – Why should we pay for something so imprecise?(41) Cantilevers – We’ll never get to 1 ach50 and no thermal bridging without eliminating cantilevers.(42) Homes without advanced framing – See excess wood above.(43) Stick building – We might as well just go all the way and admit that stick building is the root of so many problems with home building.(44) HVAC contractors – The industry is broken. It’s time to start over.(45) Home builders – Ditto (what I said about HVAC contractors).(46) Windows – One of the biggest liabilities for heat loss/gain and moisture problems.(47) Skylights – A particularly bad kind of window that deserves to be singled out.(48) Site-built homes – The only way we’ll ever get good houses is to build them in factories in China.(49) Blower door testing – We should use that money for air sealing instead.(50) Single-family homes – Too inefficient.(51) Tiny houses – A fad for millennials who don’t know they’re just expensive trailers.(52) Mansions and McMansions – Just as no one needs more than 640 kB of memory in their computer, no one needs more than 500 square feet person in their home.(53) Ugly houses – As Joe Lstiburek said, “Ugliness is not sustainable.”(54) Energy Star New Homes Version 3 – Builders abandoned it in 2012 anyway.(55) LEED – Can we really support a program that requires all-glass houses!?(56) Passive House – A boutique program for architects who think they can do physics.(57) Know-it-all bloggers – Someone’s always got to come behind them to dispel the myths they create when they try to dispel myths.(58) Stack effect – Too controversial.(59) Psychrometrics – Too complicated. Have you seen that chart!?(60) Rain and snow – The cause of so many problems with houses.(61) Hot and cold weather – A terrible waste of energy.(62) Occupants – The number one reason high-performance homes never reach their full potential!OK, that’s it… for now. Clearly we have some issues in the world of home building. And as you should have been able to figure out by the time you got to the bottom of the list, I don’t really think we should ban all these things.The root of the problem isn’t really using the wrong products or even doing things the wrong way. It really boils down to motivation. Builders are motivated to build to code when they know they’ll have to pass inspections. They’re motivated to build energy-efficient houses when there’s demand for them. They’re motivated to build houses without comfort or moisture or IAQ problems when they’ve had too many callbacks to fix those problems.Of the 62 items on this list, there’s only one I would definitely like to see banned: ventless gas fireplaces. I’d like to see less of some of the others or better ways of doing them, but I think the real problem is getting home builders and other stake holders — including home buyers — motivated properly.And the good news is, as Joe Lstiburek likes to say, the gap between stupid and hurt is narrowing.

The steady increase in sightings of salt water crocodile nests in the swampy creeks of the Bhitarkanika National Park on the Odisha coast for three consecutive seasons has elated ecologists, who have hailed this achievement as the outcome of long-term conservation efforts.The wildlife wing of the State Forest Department has come across 80 crocodile nests in their wild habitats in 2017 in Bhitarkanika, compared with 75 in 2016 and 70 in 2015.“We have spotted 80 nests in the wild. But the number of crocodile nests could be more as we could not trace all of them due to inaccessibility. Of the 80 nests, 70 are in the Kanika range. For the first time, we discovered three crocodile nests in the Gahirmatha range,” Bimal Prasanna Acharya, divisional forest officer of the Rajnagar Forest Division told The Hindu on Tuesday.Bhitarkanika is said to house 70% of India’s estuarine or salt water crocodiles, conservation of which was started over four decades ago in 1975.Back then, when the Government of India and the United Nations Development Programme focussed on saving crocodiles in Bhitarkanika, there were hardly three or four nests sighted in the area and the population of salt water crocodiles was estimated to be 95, including 34 adults. Now, the numbers have grown to 1,682.Long-term effortSince 1977, salt water crocodile eggs have been collected and young crocodiles have been released in the creeks and the estuaries of Bhitarkanika. A decade ago, this practice was discontinued, allowing crocodiles to grow in their natural habitats.“More than 3,000 crocodiles have so far been released into the waters of the Bhitarkanika. We have been able to reverse the trend of a declining crocodile population and make the area a safer habitat for the reptile,” said Sudhakar Kar, a former scientist with the Odisha Forest Department and an expert on crocodiles with the International Union for Conservation of Nature.The Bhitarkanika National Park is a place where the rivers Brahmani, Baitarni, Dhamra and Pathsala meet the Bay of Bengal. The mangrove wetland and a large number muddy creeks provide perfect conditions for estuarine crocodiles to nest. Moreover, the nesting sites of crocodiles are located at places where tidal waves cannot wash away the eggs.“Unlike other crocodiles, estuarine crocodiles lay eggs by creating a mound made of leaves of a particular mangrove species, which are plentifully available in Bhitarkanika. Other crocodile species dig the soil for laying eggs,” said Dr. Kar.Crocodiles start laying eggs by mid-May, with an incubation period of 75 days. The female crocodile guards the nest devotedly for three months. During this period, she tends to attack anything that approaches the nest. Hatchlings come out in the month of August. An average of 25-30 eggs are found in a nest and 30% of hatchlings may finally survive.Dr. Kar said there are large habitats for salt water crocodiles in the Sundarbans in West Bengal, and in the large mangrove wetlands of the Andaman Islands, but they cannot match the density and population of crocodiles in the wild habitats of Bhitarkanika.The national park is also home to the only white-coloured captive crocodile named Gori. Many albino crocodile species can be found in the Bhitarkanika’s waters. The park also houses the world’s largest salt water crocodile, measuring about 23 feet — this was recorded in 2006 in the Guinness World Records.Dr. Kar said, “Salt water crocodiles devour predatory fishes. Hence, more fish thrive with the presence of crocodiles in the water.” He added, “The existence of salt water crocodiles depends on dense wet mangrove forests and the steady discharge of fresh water into the sea. Odisha has the distinction of having all three Indian species of crocodiles. ”
Senior Trinamool Congress (TMC) leader and MP Abhishek Banerjee on Wednesday set a target of winning 250 plus seats in the next Legislative Assembly poll. Abhishek, who heads the youth wing of the TMC and is nephew of Chief Minister Mamata Banerjee, said the BJP’s thinking of winning Bengal has no basis.“In the next assembly poll in 2021, we should fight to win 250 plus seats in the state. The BJP thinks it can win Bengal. But they are wrong. If our party supremo Mamata Banerjee permits, we would score 10 goals against BJP everyday and they won’t stand a chance against us,” Mr. Abhishek said while addressing TMC’s students wing-Trinamool Chatra Parishad- foundation day rally here. The total strength of the West Bengal assembly is 294. They (BJP) has emptied the coffers of central government and RBI and are lecturing others on financial issues, he said. While referring to Reserve Bank of India (RBI)’s decision to give Rs 1.76 lakh crore to the Centre, Abhishek said the reserve money of the central bank has also been exhausted due to the ruling Bharatiya Janata Party (BJP) government. BJP’s West Bengal unit president Dilip Ghosh, while reacting to Abhishek’s claim, said he is living in fool’s paradise.“He is living in fool’s paradise if he thinks that TMC will win 250 seats. The TMC would find it tough to get even 30 seats and acquire main opposition party status,” Ghosh said. The BJP, in the general election this year, bagged 18 of the 42 seats in the state, four less than the ruling TMC.The TMC’s tally came down from 34 in 2014 to 22 seats. In the last few years, the saffron party has made deep inroads in Bengal and emerged as the main challenger to the ruling TMC by pushing the Congress and the Left Front to distant third and fourth positions respectively. It’s leaders are now asserting that their next target was to unseat Mamata Banerjee in the 2021 assembly elections.
The second half began with a City onslaught but Lloris’s diving save kept out Sterling’s low shot and one-handed save palmed an effort from De Bruyne around a post.The first flickers of a Spurs threat in the second half came when Llorente dived in with a header but it lacked power and was blocked by goalkeeper Ederson.And the momentum swung again when City scored its fourth in the 59th.Ilkay Gundogan’s crossfield pass landed at the feet of De Bruyne, who drove forward before slipping the ball through to Agüero who beat Lloris at his near post with a powerful shot.For the first time on the night, City was in front on aggregate and on course for its second Champions League semifinal.But the hosts couldn’t close the game out.When Trippier whipped in a corner, Llorente rose and turned the ball into the net with his hip.The celebrations were put on hold when the referee went to the touchline to check if the ball came off Llorente’s arm, but the goal stood.As the Premier League champions chased the goal that would sent them through, Aguero had a header saved by Lloris and an effort from Gundogan was scooped over.When Sterling did find the net again, VAR intervened to leave the home fans crushed.

Tourism and Entertainment Minister, Hon. Dr. Wykeham McNeill, is slated to announce details of several major projects, being earmarked for implementation within the industry, when he makes his contribution to the 2013/14 Sectoral Debate in the House of Representatives on June 12.Speaking at the Jamaica Hotel and Tourist Association’s 52nd Annual General Meeting (AGM) at the Sunset Jamaica Grande Hotel, in Ocho Rios, St. Ann, on Saturday, June 1, Dr. McNeill pointed out that the projects are expected to be “transformational”, while pointing out that the Tourism Enhancement Fund (TEF) will have a pivotal role in implementing these.“The Tourism Enhancement Fund must be a transformational body. I want to see big projects that make a difference to Jamaica,” he stated, while adding that the TEF’s input will also be outlined during his sectoral presentation.The Minister disclosed, however, that consultations have commenced with stakeholders in Ocho Rios regarding the projects to be undertaken in that area. He pointed out that these talks have gained resonance among the parties with whom the Ministry has been dialoguing.Pointing out that projections for the 2013 summer and winter tourist seasons are “looking good”, Dr. McNeill appealed for continued collaboration among all sector stakeholders, “in the interest of the industry”.“I think our partnership is a really strong and good partnership; and it is something we can use as an example for the entire country, when we are all working together to develop Jamaica, land we love,” he stated.The Minister, however, lamented continuous reports being received about the extent of visitor harassment occurring, particularly in the resort areas, which, he asserted, must be decisively addressed.In this regard, he informed that the Ministry has initiated discussions with several key stakeholders, inclusive of the security forces and the judiciary, to institute measures that will curtail such undesirable behavior.“Over the years we have discussed the issue of harassment in Jamaica, and I have taken the initiative now to address it seriously. We have been having discussions, and we are going to be looking at the issues of anti-harassment. Right now, we are doing some work to this end in Ocho Rios, because it is important,” he disclosed.Dr. McNeill contended that if this scourge is rooted out, Jamaica’s tourism industry will be transformed significantly, resulting in increased visitor arrivals, yielding dividends redounding to the country’s long-term benefitContact: Bryan Miller
