KPJ. The Difference that Makes a Difference

KPJ. The Difference that Makes a Difference Wood makes a difference because in the Whole Life Analysis timber windows have the lowest cost over a 60 year life.in comparison with other types. Here are the advantages of choosing KPJ as your supplier: 1. KPJ uses advanced technology in the manufacture of its energy efficient wooden windows, doors and mouldings. 2. KPJ products have been tested independently to meet NBR standards and now we have our very own, scientifically designed, testing equipment to ensure our rigorous standards, way beyond those required by the NBR, are maintained in-house. 3. All KPJ products have simulated performance values - see attached specimen frame+glass certificate 4. KPJ cares for the environment. KPJ uses hardwood, sourced from sustainable forests, that is carbon negative according to the Wood Window Alliance Global Warming Potential Study June 2013, partly due to its ability to absorb large amounts of carbon dioxide. 5. The Institut for Climate Change has graphed evidence that CO² level in the atmosphere has been, and still is, increasing exponentially and the oxygen level is falling. They are calling for a change in the way we treat the environment for the sake of generations to come.

Are You Converted?

STEEL TO WOOD CONVERSIONS ON RESIDENTIAL PROPERTIES K. PARKER JOINERY has considerable experience in converting steel windows to wood. You are not inconvenienced during the conversion. There us no better time than NOW to convert · No breaking of walls · The steel window is removed · The steel frame is left in place · The wooden window is fitted into the steel frame · Wood cladding is placed over the steel frame · The wood conversion is complete · No fuss. No bother. A South African highveld case study shows that there is a 20% saving in heat conductance when steel windows are converted to wood.. This can be increased further by using shading or up to 50% if low E glass is used. Therefore conversion is a move to more energy efficiency in the house.

The Benefits of Laminated Glass

K Parker Joinery The GREEN Movement has drawn the attention of Developers, Architects and Builders to the energy saving benefits of laminated safety glass K.Parker Joinery has been supplying wooden windows and doors with safety glass to clients who are now designing and building houses for energy efficiency. A key measure for rating the energy efficiency of a product is its U value. The higher the U value the more heat flows through a building component so a good value is a low one as you want to keep heat inside the building or outside depending on the time of year. Living in a building that has low U values has a number of advantages: It saves money on the energy bill It helps preserve the environment It is good for your health It gives better indoor comfort Suppliers of energy efficient glass have worked out U values for their products and several choices are available to clients. We have looked at the advantages of two ranges, Low E and SOLARVUE™ SOLARVUE™ Neutral glass has a U value of 5.8 It limits the sun’s energy entering a room This means it is better if your interest is to keep rooms cool in summer The Low E (emissivity) Range Clear glass has a U value of 3.4 It limits the amount of heat leaving a room Therefore it is better for keeping rooms warm in winter If you have any questions regarding energy efficient glass please contact me and I am only too happy to give you answers. Using energy efficient glass includes adding rubber seals to all window openers to ensure a better fit and adding rubber seals to all external door frames. Windows lose and gain heat in four ways, by conduction, convection, radiation and air leakage

K Parker Joinery Why Choose WOOD? We are in a very competitive industry and the benefits of choosing wood for residential buildings is often forgotten so I would like to go over some good–for-wood points in the light of the growing movement for energy efficiency. Apart from being an aesthetically pleasing material, wood is far easier to work with than is often understood. By knowing the facts you can make a more informed decision about whether wood is the right material for your project. Our specialty is the manufacture of quality wooden windows, doors and mouldings of all designs. Let us look at the facts. Wood has the best thermal insulation properties of any mainstream construction material. Saves money on energy bills. Wood's cellular structure contains air pockets which limits its ability to conduct heat and gives it this good insulation. Aluminium in comparison has no air pockets and is an excellent conductor of heat which is why it is often used for cooking pots so you can imagine what happens in a house. Aluminium increases energy bills. Glass is a good conductor of heat,(ever felt your steering wheel after your car has been left in the blazing sun) that is why we are now promoting LowE glass which is an energy efficient alternative. It gives you better indoor comfort. LowE glass saves money on energy bills. Wood has the best long lasting properties. An extreme example: In 2011 Archeologists found 7000 year old timbers buried in the silt below the MI6 HQ on the banks of the river Thames. Wood structures built hundreds of years ago are still standing in Russia. Wood gives long lasting savings on energy bills

More on LowE Glass

I find that interest in energy efficient windows is increasing especially in regard to LowE glass and more explanation of its benefits has been requested. I also want to emphasize the insulation value of wooden frames. New Building Regulations relating to energy efficiency (SANS 10400 XA&SANS 204) include new and replacement windows and doors and it came into force on 10th November 2011. LowE (Emissivity) refers to the ability of glass to suppress direct heat radiation and absorb indirect heat radiation. The glass is coated with a very thin layer of silver on the inside of the first of the two sheets of glass. We install glass in all the windows and doors we supply so you have the confidence in knowing it will be installed properly. It is worth pointing out that heat radiation remains on the side of the glass it originated, the heat sources remain inside the home during winter months and it will keep the inside of the home warmer. In summer some of the heat is reflected away so it will keep the inside of the home cooler. How does LowE glass work? The effect of LowE glass is based on the angle of direct solar radiation Due to the sun’s differing angles during summer and winter the LowE glass works well in all seasons. In summer, when the angle is direct, some heat is reflected back outside. In winter, when the sun’s angle is less direct, indirect heat is absorbed and reflected back into room. Being cool in the summer and warm in winter is a good thing. Glass is a very good conductor of heat. It has a higher U value than most other building components. All building components need to be insulated for it to be energy efficient so windows and glass doors should not be left out of the equation because the end benefits are lower energy bills and a much more comfortable home to live in. Please try this yourselves; In regard to the frames used for the glass, touch the inside and the outside of aluminium frames now that it is winter, you will find they are equally cold, yet when you touch the inside of wooden frames it is quite warm compared to the outside. I am sure you will agree the wooden frame is so much better insulated. We are offering an economic way of installing energy efficient windows and doors in the Highveld

What is Your Visibility Rating?

I still feel a need to expand on our prime goal and focus on our manufacture of Quality Energy Efficient Wooden Windows, Doors and Mouldings. My question above relates to the role that windows play in a building's use of energy. Windows are not like Walls and Insulation Materials used for walls, roofs, ceilings and floors are insulated to resist the conduction of heat and are measured in R values. High values are more energy efficient. Windows are very different from walls and ceilings. Windows: 1. Let in light and allow people to see out. The visible transmittance rating for clear LowE glass is 82, so 82% of light comes through the glass 2. They interact with their environment in ways that insulation does not. 3. They react to outside air temperatures, sunlight and wind 4. They react to indoor air temperatures and occupant use 5. They are strongly affected by solar radiation and the airflow around them. Therefore, the window industry measures their products in terms of Thermal Transmission or U Value. This takes into account the affect of the airflow around the window and the emissivity of the glass. Low values are more energy efficient. A short term investment in an energy efficient home will bring long term savings in power bills, especially as forecasts indicate a dramatic increase in power costs over the next several years.

Is There a Downside to LowE?

MANUFACTURERS OF ENERGY EFFICIENT WOODEN WINDOWS, DOORS AND MOULDINGS Is There a Downside To LowE? Not according to the many glowing testimonials I have read on the Internet coming from the USA where LowE glass has been on sale for over 20 years. The prime concern with the early products seems to have been if solar heat gain would be limited and therefore not keep the house warm in winter months. Today, the high performance LowE glass products deal with that and other requirements. Another concern is the initial cost but the long term savings in money spent on power in the home outweigh the increased cost over untreated glass and make LowE an economic choice. How Can You Become More Energy Efficient? There are often different needs based on where you live, the orientation, your goals and how the sun's rays shine in your living room/s and other rooms. There could be a change in how you look at the usage of different areas of the house. How lighting might change, or how curtains and widow treatments will change. There are many aspects to consider. Once you have done an assessment of your needs in each room in your home we can advise on how you can best achieve your ideal in regard to light and heat to make your home as bright and comfortable as possible in every season of the year. What can you expect from LowE glass? In summer, temperatures on the Highveld can rise to 30°C on the outside. LowE keeps damaging UV out and will limit the transfer of heat from direct sunlight to about 23°C or less and maintain it, thus reducing or removing the need for A/C 89°F= 30°C. 75°F= 23°C In winter, when the High Pressure returns to the Highveld, inside temperatures can be maintained at about 20°C on sunny days, thus avoiding the need for heating. On overcast cloudy days it will be necessary to use the heater for short periods to make the home comfortable 70°F= 20°C It is not only the infrared (which causes the heat) that is blocked but also the ultra violet (which causes fading) Change to LowE and live in a Brighter and More Comfortable Home

Does Shading Make LowE Glass Less a Effective?

Does Shading Make LowE Glass Less Effective? I have been asked about the effect of shading on LowE glass and I feel I should make a comment. The Building Regulations SANS 204 requires that the roof overhang is capable of restricting at least 80% of summer solar radiation from going directly into the building. Of course, there are other forms of shading e.g. curtains, blinds etc. but how does this affect the benefits of LowE glass? If we look at the aim of energy efficient glass we judge it by the internal effect of the comfort it gives to a room. Whatever the external flow of infrared radiation in summer or winter, LowE glass will either reflect or absorb it according to its U value ( Heat Transmission) and we know this glass will help to maintain room temperature at optimum levels in summer and winter. Your decision whether or not to opt for LowE glass has a cost consideration. What is the alternative? KPJ is a SAFIERA accredited manufacturer of energy efficient windows so you have a choice of whether to go for the optimum or something slightly less optimum. You can still meet the deem-to-satisfy requirements of the New Building Regulations The Energy Efficient Solution Install KPJ Quality Wooden Windows, Doors and Mouldings.

The Scorecard Made Easy

SARIERA Accredited Manufacturer of Energy Efficient Windows The Scorecard Made Easy We have acquired some useful experience in quoting and supplying our clients with energy efficient windows so I can share a few helpful tips that may save you time when preparing plans for new buildings, additions and alterations so that they comply with SANS 204 in climatic zones 1 and 2 Windows in naturally ventilated buildings must comply for conductance, solar heat gain and the SANS 613 SAFIERA tests for air tightness An assessment must be made for each floor level separately 1. SANS 204 applies when the total of the windows area m² exceeds 15% of the habitable net floor area m² Assessments must not exceed the constants listed in SANS 204 2. For assessment of Conductance: List: a) Window sizes, the type of glass in each window and the U Value of each window b) Area m² of each window c) Net habitable floor area m².of building Here are some examples of glass U Values and SHGC in Timber window frames. TIMBER TIMBER Glass Description frame U Value SHGC Glass Description frame U Value SHGC Single Clear 5.6 0.77 Clear Double 3. 0.68 Single Tinted 5.6 0.65 Clear Double LowE 2.41 0.62 Single LowE 4.06 0.63 Clear Double Tinted 2.41 0.51 d) You can now calculate the conductance: Am² (glazing) x U Value (glass + frame) for each window to get a total) e) You can then compare the result with the Conductance constant in SANS 204 f) A(net floor area m² ) x C (zone 1 = 1.2 zone 2 = 1.4) How to calculate shading. P is measured horizontally from top of glass to the edge of the projection. H is measured vertically from the base of the glass to the edge of the projection. The P Value is calculated by dividing P with H. G is measured vertically from top of glass to the edge of the projection. Example: P = 500mm H = 2000mm P/H = 0.25 How to calculate P/H when G exceeds 500mm. The H is halved. 3. For assessment of Solar Heat Gain List: a) Area of each window m² = A b) The SHGC = S for the type of glass in each window c) Orientation (8 possible sectors) N, NE, E, SE, S, SW, W, NW., d) Shading – see graphic above (from unshaded to total shading by adjustable means) e) Get the P/H value and convert to E (Solar Exposure Factor) (see Table C1 and C2 in SANS 204) f) You can now calculate the solar heat gain. A(glazing) x S x E (for each window to get a total) g) You can then compare the result with the SHGC constant in SANS 204 A(net floor area) x SHGC (zone1 = 0.15 zone 2 = 0.12) 4 Air Tightness of windows per SANS 613.

How to become more energy efficient

Where Can You Get Information On Energy Efficiency? I am hoping that my blogs have helped to explain how the future of new and renovated buildings will be impacted by the new regulations in SANS 10400 XA and SANS 204 particularly with regard to fenestration. The most important part of the building is the fenestration because that is where you can save the most on energy bills. KPJ expertise in this area has been proven in several tests. I have made sure our window and door frames meet the highest standards of manufacture. KPJ is an accredited quality manufacturer having passed three levels of tests for windows - A1, A2, and A3 - by an independent laboratory and results certified by SAFIERA. The regulations only require A1 so KPJ is superior and supplies the best possible product in wooden windows and doors. Always ask your supplier to let you see his certificates I have now summarised all the knowledge we have acquired and made revisions to our website. Please visit us at www.kparkerjoinery.co.za I have left out much of the technical details so you can see the easy way of ordering energy efficient glass. SMART GLASS has reduced their range of LowE glass to two products that are available ex stock. ENER G SMART Laminated Single Glazed and InsulVue SIG Double Glazed These LowE products are the result of taking the best of Solarvue and Solar Shield, which were part of their previous range, to satisfy the requirements of the new Building Regulations SANS 10400 XA and SANS 204 Plans of windows and doors have to be assessed for regulation compliance of conductance and solar heat gain.

LowE Fenestration Simplified

SARIERA Accredited Manufacturer of Energy Efficient Windows LowE Fenestration Simplified Energy efficient fenestration appeared quite complex when we first heard about it. If you look at the European or the USA situation it does seem that architects and material suppliers have to accommodate a large number of factors when complying with building regulations. However, in South Africa we are fortunate that the climate makes it easy to decide on fenestration planning although architects do have to consider all parts when designing energy efficient buildings. Low E glass means that windows have to be as large as possible because the coating on the glass reduces light transmission but that brings a benefit in winter as there is a larger area to reflect heat back into rooms. You only need to decide between two types of LowE glass - Single Glazed or Double Glazed. Then there is the window frame and KPJ works with wood which is the ideal insulator for energy efficiency. Compliance with SANS 613 is essential and suppliers of fenestration have to be able to show a certificate from SAFIERA. It means windows and doors have to pass tests for air tightness, water resistance and structural strength. KPJ has had its windows tested extensively by an independent laboratory and we have proven that our products meet the highest international standards. KPJ is the leading manufacturer of energy efficient windows, doors and mouldings in South Africa

LowE FAQ

SARIERA Accredited Manufacturer of Energy Efficient Windows I am going to cover two important questions that have arisen lately. 1. The frame+glass U values KPJ has complied with SANS 613 achieving an A3 status for KPJ side, top hung and fixed range of windows. This means every product has passed independent laboratory testing for air tightness, water resistance and structural strength (minimum deflection). According to published data no other joinery in South Africa has achieved a rating of A3 for single glazed windows. Tests results are rated according to the European (EU) Code A-G. A Rating is the most energy efficient. A1 is the rating required for residential buildings in Gauteng. Heat Transmission (HotBox) testing is needed to establish U values for frame+glass. Numerous studies in the northern hemisphere have shown that all types of wood are used for windows because it is an excellent insulator. Wooden frames in Europe have been given U values that can match the U values of LowE glass available on the South African market. 2. Pricing To get the best price of single or double glazed LowE windows and doors you will need to choose sizes of windows that can be optimized within the size of sheets of glass (3210x2250mm) as supplied by the manufacturer, so it is advisable to get a quote on a full schedule to see the effect of costs.

Retrofit For Energy Efficiency

SARIERA Accredited Manufacturer of Energy Efficient Windows Retrofit for Energy Efficiency Since 2012 the interest in retrofits increased with energy efficiency in mind. We benefited from an increase in the demand for steel to wood conversion in windows and the popularity of outdoor living gave us the opportunity to supply more patio wooden folding and sliding doors. KPJ now supplies folding and sliding doors with lowE glass bringing much needed temperature control to outside living. KPJ is in its 17th year in business and we use the experience we have gained to offer the very latest technology in our products and installation support. This avoids common difficulties homeowners can experience with installations. South African homes generate about 35% of all carbon gases in the country. I would welcome feedback from clients as retrofits do appear to be a lucrative market.

Where to Find the Best Watt

SARIERA Accredited Manufacturer of Energy Efficient Windows Where to Find the Best Watt I attended the regional meeting of SAGGA . It was very well attended by manufacturers. The subject under discussion was the New Building Regulations. We were informed that the NRCS (National Registrar Compulsory Specifications) has directed Municipalities to enforce the regulations. Municipalities have appointed Building Control Officers to carry out this function. It means that requirements will be inspected at the plans approval stage by a Competent Person appointed by the owner. Drawings will need to have energy efficiency details listed and contractors will need certificates from product manufacturers ready for inspection. FENESTRATION In regard to fenestration, manufacturers are required to comply with SANS 613 and supply the necessary certificate of compliance. In addition, it is the manufacturers' responsibility to be able to give architects assurance that they can supply windows and doors to their energy efficient specifications. SANS 613 KPJ has a certificate of compliance with SANS 613 for windows. KPJ's windows have an A3 rating which shows our products are stronger and better because they have undergone more stringent testing than products with a minimum required rating of A1. Products must be rated to meet the Building Regulations standard. HOTBOX KPJ windows have undergone 5 day testing in the HotBox so we can give you an up-to-date U Values and SHGC. The results have given us a certified overall picture of KPJ wooden windows. (Heat Transmission - U value, SHGC, + A3 rating of SANS 613) SAVE 40% Watts with KPJ Windows Now let me turn to the important Watt. According to the Performance values for frame+glass published in SANS204 we have a distinct advantage when it comes to choosing the right energy efficient window (frame+glass) because choosing KPJ single or double glazed wooden windows will save you adding at least 40% more heat transmission, either gain or loss, in the home if you choose other frame materials such as aluminium or steel. Heat transmission is calculated in Watts so just imagine what 40% saving can mean to the comfort in the home and saving on energy Your Guarantee of Excellence KPJ windows have been tested and certified by AAAMSA, SAGGA and SAFIERA KParker Mouldings Website We have launched our new website.

U Values and SHGC for KPJ Products

U Values and SHGC of KPJ Products We have achieved great success with our standard single pane Premier range of Side, Top and Fixed windows achieving an A3 rating. The process is expensive with an outlay of R37000.00 to get the SANS 613 (Performance Test Certificate) and SANS 204 Rotatable Guarded Hot Box (RGHB) certification (Energy Rating Certificate) for a SINGLE product. The process of obtaining the U-factor (in W/m².K) is first to submit the product for RGHB test (which can only be done after obtaining SANS 613) then to have the results independently verified by simulation. Should the RGHB and simulation results be within 10% this is deemed acceptable and simulation of the ranges can be done. We are currently working closely with the simulators submitting samples of our seals, Meranti, types of treatment, and hardware so the simulation is as close as possible to the actual results. The simulation is also an expensive exercise and this depends on the complexity of the product. Costing ranges from R300.00 per item. Prices quoted for simulation of 200 windows is around R100 000.00. The SHGC is largely dependent on the GLASS, however Steel and Aluminium without a thermal break are generally a great Hi-Way for conductance increasing the overall SHGC. Thus Timber will give a better SHGC and the more timber there is the better the SHGC.

Free Windows!!

REPLACEMENT WINDOWS Last year I replaced all the windows in my house with those expensive, double-pane, energy-efficient kind. Today, I got a call from the contractor who installed them. He complained that the work had been completed a year ago and I still hadn't paid for them. Helloooo,............ just because I'm blonde doesn't mean that I am automatically stupid. So, I told him just what his fast-talking sales guy told me last year... that these windows would pay for themselves in a year. Hellooooo? It's been a year, so they're paid for, I told him. There was only silence at the other end of the line, so I finally hung up. He never called back. I bet he felt like an idiot.

The Aim of the SHGC Constant

The Aim of the SHGC Constant SANS 204 describes several options for architects to reduce exposure of windows to solar radiation and uses the Constant to hold the designer to a window area limit in each cimatic zone. Radiation is the movement of heat as infrared energy through glass. The New Building Regulations require that the SHGC Constant must apply to the combined effect of the frame+glass. The SHGC CONSTANT for Johannesburg and environs is 0.15 and for Pretoria and environs it is 0.12. These figures represent the equivalent percentage of the net floor area of each storey of a building that can be exposed to solar radiation through windows. Without the product Thermal Test figures you have to use the worst case Table 6 in SANS 204 to calculate your plan against the Constant. For example, in the single occupancy building in Zone 2 shown in SANS 204 with a net floor area of 60 square meters only the equivalent of 12% or 7.2 square meters of window area per storey is allowed UNLESS you can reduce the exposure factor with a combination of better orientation, well placed shading and choose a product with a lower SHGC. KPJ wood shutters placed outside windows that are exposed to solar radiation will make a big contribution to meeting the Constant Thermal testing of frame+glass will show the real SHGC of the product. The resulting figure will depend on the type of frame and glass used and how well it prevents solar radiation from being transmitted through the window. The importance of having the Thermal Test figure is that the architect can choose the right product to maintain the goal of keeping the building bright and airy. You will always start your plan with a lower SHGC by choosing KPJ wooden windows and glass doors You Can Do More with Wood Your Guarantee of Excellence KPJ windows have been tested and certified by AAAMSA, SAGGA and SAFIERA SARIERA Accredited Manufacturer of Energy Efficient Windows

The Municipal Plans Department asks the applicant (the Owner) to nominate a professional from one of the building services to become the Competent Person who will make sure all parts of the Building Regulations are complied with when construction plans are passed and put into effect. Once the person accepts, the responsibility rests with the Competent Person to act on behalf of the Owner. What does SANS 204 say about fenestration? There are two important Regulations 1. Architects must ensure that the manufacturer of the windows and doors has a SANS 613 Performance Certificate issued by AAAMSA on behalf of SAFIERA. This applies to every construction of residential or commercial building. This certificate ensures that the manufacturer has had his products tested independently and passed the minimum requirements for air tightness, water resistance and structural strength. KPJ has the required certificates as our products have been tested and in most cases far exceed the minimum requirement. 2. In order to conserve energy demand fenestration products must not exceed the Constants for Conductance ( U Value) -heat leaving the building and Solar Heat Gain - heat entering the building, on each floor of the building. To help manufacturers who have not thermally tested their products SANS 204 provides a default list of worst case U values and SHGCs that can be used to do the calculations. This lists covers several different glazing options for a) metal frames and b) wooden frames (wood offers the best values.) Thermal testing of products will signifantly reduce these U Values and SHGCs. KPJ has made a very large financial investment in getting products thermally tested and simulated. Several windows have been tested and we can offer clients much lower U values and SHGC than those in the default list. The importance of having products thermally tested is that all sizes of similarly constructed windows and doors can be simulated to give the whole range lower U Values and SHGCs. KPJ simulations make it much easier for architects to meet the Constants. How are Simulations performed? Simulations are done after the data is received from Hot Box thermal testing of windows and doors that include glazing. The model that is thermally tested is 1200mm x 1500mm and when similar structures are used for different sizes the data for each window and door is collected and the model is scaled to simulate U Value, SHGC, and Visual Transmission. It can take into account any type of glazing as well. The formulas used for simulations are taken from the NFRC.

ENERGY MODELLING

MANUFACTURERS OF ENERGY EFFICIENT WOODEN WINDOWS, DOORS AND MOULDINGS K.Parker Joinery SAFIERA Accredited Manufacturer of Energy Efficient Wooden Windows and Doors GREEN BUILDING Here is an interesting article I received from Mike Barker of Building Physics. Mike is helping us to improve the standard of our products through simulations of U value. SHGC and Visual Transmittance. Striking a Balance The energy modelling approach allowed for by SA’s building energy usage regulations provides an attractive alternative to SANS 204 Is it possible to put up a better building at a lower cost and without the limitations of SANS 204? South Africa’s building energy usage regulations are not as restrictive as some may lead you to believe. The energy modelling approach allowed for by the regulations provides an attractive alternative. Project managers often act as client representatives and in doing so they take on the role of optimising the budget rather than just meeting it. In other words, they seek to squeeze the most value out of a project – both in terms of the delivered building and its long-term operating overheads. Avoid the constraints PMs will therefore be most interested in all the compliance routes allowed by SANS 10400 Part XA: “Energy usage in buildings”. Made mandatory on 9 November 2011, the amendments to the act require that buildings are designed and constructed so that they “are capable of using energy efficiently”. SANS 10400 XA, in turn, references the SANS 204 Standard: “Energy efficiency in buildings”. This is where a good deal of confusion arises. SANS 204 has been around for a few years and it’s easy to assume it’s the only game in town. But blindly following the SANS 204 prescriptive route will not necessarily deliver the least costly design or save the most energy. It is also important to bear in mind that 204, while a good starting point, is immature and untested. It does not take much to improve a typical South African building and therefore 204 did not have to do much to appear effective. However, what little it does, is very restrictive. Compared to other international building codes that are now over 30 years old and have had the weaknesses knocked out of them by good architects, wise quantity surveyors and even lawyers, SANS 204 has a long way to go. There will always be better ways to go about the business of designing energy efficient buildings. Two alternative compliance routes are expressly detailed in the act: 1. A rational design approach that demonstrates the energy usage of the building is equal or less than that of a baseline SANS 10400 XA building. 2. The theoretical energy usage, determined using specific software, is less than that of a baseline building as specified in SANS 10400 XA. How exactly is all this done? The answer lies in modelling the energy used by the buildings, using specialist software to simulate the annual operation of the building. This can then be utilised to improve a building’s design and to make informed decisions about the cost trade-offs. Energy modelling is a tried and trusted method widely used by modern integrated project delivery processes that are promoted by architects and engineers (e.g. American Institute of Architects, Royal Institution of Chartered Surveyors, and even PMBOK to a degree). Integrated design requires a detailed understanding of interactions in a building, and modelling should be incorporated early in the design process. To gain extra credits, energy modelling has been used extensively on over 15 000 LEED buildings and by the GBCSA’s Green Star rating tool too. Using a set of detailed equations that factor in every effect – from that of the envelope’s solar gains to HVAC performance – modelling calculates the energy used every hour of the year. A typical weather file and the schedule of the operations of the building are used. Such detailed calculations are precise, repeatable, and a least-risk rational design. Modelling is all about getting the balance right, of ensuring the design uses fenestration, thermal mass, and insulation in the right quantities and in the right circumstance to provide a building that is not only thermally and visually comfortable, but uses energy and materials responsibly. PMs need to be aware that Part XA further requires that an accredited energy modelling software be used. There are two Agrément SAapproved packages available currently. Moving toward net zero buildings Legislation in Europe requires new buildings to be so efficient by 2030 that they will have an annual net energy consumption of zero. This effectively avoids having to build new power stations, which has made our government take notice. Government is expected to follow up SANS 10400 Part XA with legislation requiring buildings to display labels showing their audited energy usage. The results of an energy efficient design will be there for all to see, with the building’s owners and prospective tenants able to pass judgement. Energy modelling as a rational design route is open and transparent and can withstand scrutiny by all parties involved. It assists the whole team to make decisions based on well-established building science. As such it is the least risky design option, and an invaluable tool that is available immediately to optimise building costs.

Do You Have SANS 613 Certificates for your Building?

Do You Have SANS 613 Certificates? THE NBR ACT REQUIRES SANS 613 CERTIFICATES FOR WINDOWS AND DOORS IN ALL NEW HOUSES AND RENOVATIONS. KPJ CAN SUPPLY YOU WITH SANS 613 CERTIFICATES Almost daily I get calls asking me for information and advice on the new energy efficiency laws and how they affect their building and renovations.(re: SANS 10400 XA and SANS 204) The NBR Act includes the requirement that home builders must adhere to the National Building Regulations and National Standards Act 103 of 1997 as amended. A Competent Person must be appointed to ensure compliance. The Standards mentioned here refer to SANS 10400 XA and. SANS 204 Fenestration forms a very important part of the regulations and the FIRST REQUIREMENT is that ALL builders of houses must get a SANS 613 certificate from his supplier which means the supplier of windows and doors has had products tested independently for airtightness, water resistance and structural strength and passed a minimum level of A1. KPJ has SANS 613 certificates for its windows and doors and therefore can supply details to the Competent Person. How to calculate your building plans against the Constant U value and SHGC ASK KPJ for simulated U values and SHGC of wooden windows and doors (in most cases, these values are much better than the worst case values in SANS 204) You can use these simulated values to calculate your building plans against the Constant U values and SHGC in SANS 204.

Are SANS 10400XA and SANS 613 linked?

Yes,  they are linked.

 I have had MANY calls on the need FOR SANS 613 CERTIFICATION BELOW 15%  

 

REGULATION XA3 INVOKES SANS 10400 XA WHICH STATES:

4.4.4 FENESTRATION

  4.4.4.3 All fenestration air infiltration shall be in accordance with SANS 613.

 

IN SUMMARY

A)   SANS 613 CERTIFICATION IS REQUIRED FOR FENESTRATION FROM 0-15 % OF NET FLOOR AREA PER STOREY AND FROM GREATER THAN 15% 

 

B)    SANS 204 4.3.4. COMES INTO EFFECT AFTER THE 15% FENESTRATION AREA HAS BEEN EXCEEDED, THEN COMPLIANCE WITH CONSTANTS FOR U VALUES AND SHGC VALUES IS REQUIRED IN ADDITION TO SANS 613

Use Only SANS 613 Compliant Wooden Windows and Doors

KPJ's full range of wooden windows - frame+glass - (Side Hung, Top Hung, Fixed, Sliding Sash and Mock Sash) is now SANS 613 compliant for both single and double glazing (a requirement in SANS 10400 XA)

 

 KPJ has tested complete wooden windows, Side Hung, Top Hung, Fixed and Sliding Sash, in the Rotatable Guarded Hot Box (RGHB) so that the customer can choose the most cost effective GLAZING option. (SANS 204)

 

This means you can use KPJ U values and SHGCs when designing your next project. Enquire for further information.

 

We are soon to be involved in an exciting project testing TRIPLE GLAZING using local glass (economical option) to prove that fenestration will return a better value than bricks and mortar.

No need to design poky windows.

 

We are also SANS 613 compliant with Sliding Doors, Single Hinged Doors and Shopfronts 

 

 

The Essential Ingredient for Every House Plan

Almost hidden in the NBR 10400 XA standard is a requirement that EVERY window placed in a new building or renovation must have passed the SANS 613 test for air tightness.

 

Why is this important?

 

Whatever the plan you have for a new building or renovation, the U value of the frame+glass is meaningless if air leaks through the frame.

 

Every type of KPJ single and double glazed window is certified as having passed the SANS 613 test.

KPJ  has SANS 613 certificates for hinged doors and shopfronts as well.

 

Further, windows cannot be tested for thermal values in the Rotatable Guarded Hot Box (RGHB) unless they have passed the SANS 613 test.

This is your guarantee that the projected in-house temperatures are accurate.
