23 September 2015This Heritage Day, Africa’s myriad cultures will be celebrated in New York City when brain gain company Homecoming Revolution hosts its annual Speed Meet in the Big Apple. The gathering is held in affiliation with Brand South Africa.Captains of industry, African professionals, celebrities and media will meet for the two-day event, which starts with a VIP Heritage Day dinner at the trendy Kaia Wine Bar in Manhattan on 24 September. This is followed by a full-day interactive networking event at the Thomson Reuters headquarters in Times Square on 25 September.Among the invited guests are South Africa’s consulate-general Thulisile Nkosi; media executive Alex Okosi; Brand South Africa board member Thebe Ikalafeng; Paralympic footballer Ibrahima Diallo; artist Ibiyinka Alao; and fashion designer Farai Simoyi.Angel Jones, the chief executive of Homecoming Revolution, said the Speed Meet aimed to inspire Africans living in the US to come home. It would show them that the continent was full of opportunity. “We feel incredibly privileged to be playing such an important role in building our continent’s prosperity. The ‘Africa Rising’ dream can only be fulfilled if there is a significant brain gain on the continent.“There are amazing opportunities on the continent, from jobs to investments to entrepreneurial ventures. Now is the time for global Africans to fulfil their destiny of success and significance.”Speed Meet New York will introduce Africans living in the US to top employers back home, as well as provide advice on returning, property investment and relocation.The gathering in New York follows Speed Meet Jozi, which took place in August. At that event, former South African president Thabo Mbeki called on the African diaspora to return.Brand South Africa has entered into an agreement with Homecoming Revolution in order to leverage opportunities for its Global South Africans (GSA) programme. The agreement, which consists of a number of engagement platforms, including the Speed Meet, will provide exposure for the GSA programme, and assist with growing the network.For more information on this and Homecoming Revolution’s other global events visit the organisation’s website.
Don’t worry, I still have some complaintsI still wish the new standard required blower-door testing. The lack of a testing requirement was one of my key complaints about the 2008 standard, and I had sincerely hoped that it would have been required in the new version.I also have concerns about the rigor and quality control over the program verifiers. While I acknowledge that HERS and LEED providers don’t do a perfect job of quality assurance (QA) on their raters, there are regular on-site visual verifications that the rater’s work meets certain minimum requirements.HIRL reserves the right to inspect any verifier’s work, but there is no regular schedule or requirement for this, leaving open opportunities for less rigorous certification, and in extreme cases, the possibility that verifiers will certify buildings that should not qualify. Although it is not explicitly stated in the standard, any HVAC ducts located outside the conditioned space must be tested for leakage, per the 2009 IECC. Whole-house ventilation meeting ASHRAE 62.2 is required if a home or apartment tests out tighter than 5 air changes per hour at 50 Pascals (5 ach50), but since there is no requirement for blower-door testing, this seems to be to be a bit of a loose end in the program.As before, you can meet the energy-efficiency section requirements using either the prescriptive path (by incorporating a specific list of measures) or the performance path (by preparing a HERS rating or following an equivalent energy model). Interestingly, since testing isn’t required, you can complete the energy model using the following defaults values: envelope Specific Leakage Area (SLA) of 0.00036 and duct system efficiency 0.88 if all the ducts are in conditioned space (if they are not, they need to be tested as noted above).On the administrative side, they finally abandoned their clunky online scoring tool in favor of an Excel spreadsheet that appears to work well and be fairly easy to understand. In the past, I have been critical of the NAHB’s National Green Building Standard (NGBS), just as I have been of most other green building programs. While I don’t expect to lose my critical eye, I do believe I have mellowed a bit and developed new opinions about the certification process and each program’s role in the industry.I recently obtained a copy of the new 2012 NGBS and have reviewed it fairly thoroughly. My clarifying questions were answered very promptly by the nice folks at Home Innovation Research Labs (formerly known as the NAHB Research Center). Now I don’t know about their new acronym (HIRL?), but they were goodnatured when I commented about it on Twitter recently. Existing homes are addressed as wellUnder the new standard, there are two separate sections for certifying renovations. Chapter 11 covers whole house (or multifamily building) renovations, which applies to any existing building as long as any additions do not exceed 75% of the original above-grade finished space. If the addition exceeds the 75% threshold, then it must be certified as new construction.Projects must meet minimum energy and water efficiency levels, plus gain enough points in other areas to meet certification. A scoring checklist for existing buildings will be available soon.New in this version is the ability to certify sections of buildings such as kitchens, bathrooms, and basements. These certifications do not use any scoring system; rather, the project must meet all the applicable requirements listed in the standard for that project.This project-based approach runs the risk of having a so called “green” kitchen or bathroom in an otherwise poorly performing house, but interestingly, they have set a fairly high bar, requiring the use of a certain number of bio-based products, certified wood, and the preparation of a life-cycle analysis for a product or assembly.In some ways, this non-score based certification may be more complicated to meet than it first appears. What’s new and different?There has been a noticeable leap in energy efficiency from the 2008 version, based on the fact that the standard now requires a home be at least 15% more efficient than the 2009 IECC. Certification now requires a Manual D duct design for forced-air HVAC systems. It’s also necessary to follow a list of required air-sealing measures that appear to be lifted directly from the IECC, and to install insulation at Grade 2 or better installation quality.Vent-free fireplaces are no longer allowed, and wood-burning units must have doors and a source of outside combustion air. Radon mitigation is required in homes located in Zone 1. And a long list of flashing and exterior moisture management measures are required, although kick-out flashing is still optional.

Market-rate developers who may not be willing to invest in more costly certifications are using the NGBS for their projects.One of my favorite things about the 2012 NGBS is that it is phasing in quickly – after May, all projects must register under the 2012 version and the 2008 version will go away. In contrast, LEED Version 4, which is expected to be released in late 2013 is planned to run parallel to the current version for as long as three years, allowing project teams to select either version for many years to come.In this case, I think HIRL made the right choice by tearing off the bandage quickly. It does seem to me that some of what I predicted in my Green Building Program Roadkill Post is coming to pass. It will be interesting to see how it all ends up.

You can choose your goals instead of drifting. Some will tell you that you have to decide what price you will pay to have what you want, but this is not true. What you are willing to pay has no bearing on the price you pay.Success doesn’t equitably dole out its rewards. Someone may pay a lower price than you for the success you want. You might have to work longer and harder for something that you want, even when it seems easier for others.Others may have greater talent, or greater resources, or a greater hunger. Their talent may give them an advantage in producing the result you want. Greater resources can provide a tremendous advantage, especially when those resources are deployed in chasing down a goal. Hunger is a variable that is difficult to quantify, but can easily be seen and felt. When one is hungry, they start working on what they want as soon as their feet hit the floor in the morning.Success tends to prefer intrinsic motivation and to shun those who need others to manage or lead them. Goals come faster to those who are motivated because they do the work diligently and without fail, without ever having to be reminded, coaxed, prodded, or forced to do it.Those who are willing to pay the price, even when the price is unknown achieve their goals. Because they continue to pay, results accrue to them over time until, finally, they have what it is they want. At which point, the look off in to the distance and see something else on which to set their sights.
