LEED AP BD+C: Resources and Materials (Paid)-3

paid 3

This is part of a series of articles on the experience of giving the LEED AP BD+C examination. Our first article looked at why the LEED AP BD+C exam could prove difficult to crack. The following 2 weeks elaborated on 11 Essential ‘Need -to-Knows’ before LEED AP BD+C Prep (Part 1, Part 2). We then looked at LEED AP BD+C: Resources and Materials (Free). This was followed by a list of Paid Resources and Materials (Study Resources) available online, in case you felt the need for them after referring to the free items. Last week, we continued the list of Paid items – Practice Questions. Today is our final article on Paid Resources – LEED Project Experience and Direct Classes/ In-Person training/ Webinars.

As mentioned in earlier posts – If you have prior experience with LEED projects (or some sort of Sustainability background), then things become relatively easier. If not, then you might feel the need to use a guided study course, or other paid materials. Today’s article addresses this scenario.

Note: We have tested and used some of following resources and can tell you what we found useful. There are others that we feel could be good based on the credibility of the source (these have not been tried by us, so the decision to use them would lie with you). Our aim is to create an exhaustive list of materials, so that the Menu is in front of you to make your decision (our articles are not endorsing any online courses/ question banks. However, we would like to give due credit to pages that our team found useful while attempting the exam. Ultimately, it is totally up to your choice and discretion whether to subscribe to them). We have mentioned Sources Reviews, Prices (any offers), Subscription time, Important Links and Material Inclusions. All prices are rounded off to the nearest 5 or 10.

Passive Strategies: Natural Ventilation (b)

Last week we started our series on Passive Strategies in Buildings. We kicked off with Natural Ventilation (a)Why it’s needed, What needs to be doneHow and Factors important for it.

This week we look at Strategies and related Issues for Natural Ventilation.

  1. Zoning
  2. Orientation and Form
  3. Building Depth
  4. Fenestration
  5. Advanced Strategies

(1) Zoning

Building functions can be zoned according to the ventilation strategy for effective management and energy conservation. This is seen in Akshay Urja Bhavan1 where spaces are divided into zones according to setpoints – Apex, Controlled and Passive. Only around 12% of the area is air-conditioned. Mist cooling systems are used for the Controlled and Passive zones.

↑Go to Top


(2) Orientation and Form

Buildings should preferably be oriented between 0o and 30o with respect to the prevailing wind direction2. The building form can incorporate courtyards or verandahs (transitions zones between inside and outside) for increased ventilation and thermal comfort. These features temper down the harshness of the exterior environment, providing shade and cool breezes in summer.

↑Go to Top


(3) Building Depth

unit thick principle
Unit Thick Principle in 2 projects by WOHA

A building depth of around 15 meters or less would enable Natural Ventilation and Daylighting. This is an assumption based on our research of many buildings by WOHA applying their Unit thick Principle. Some buildings may not be able to achieve less depth due to larger functions such as Industrial labs.

Solution | Fragmentation of Form – Such buildings could employ courtyards or atriums to break the overall form, thus enabling light to penetrate or air to flow better. (eg. Cleantech One) Fragmentation of form is also seen in Indira Paryavaran Bhavan3, where two North-South oriented blocks are separated by a centrally running  public spine.

↑Go to Top


(4) Fenestration

  • Location, Sizing, Area – The location and size of windows, should take into account the wind direction and the ‘Living Zone’. The total area of openings should be a minimum of 30% of floor area2.
  • Window to Wall Ratio – The Window to wall ratio (WWR) should fall between 20-40% for Commercial buildings. In any case, it should not exceed 60%4.
  • Operable windows – The windows should preferably be operable with a staggered alignment. Operable windows may present certain issues. In the case of hotels for example, people might leave windows open when the air-conditioning is on, which would affect energy costs. Operable windows could also have safety implications.

Solution 1 | Sensors – Some hotels install sensors that automatically shut off air-conditioning when windows are opened.

Solution 2 | Individual Project Detailing – Safety concerns would need to be addressed in projects individually, through railing design details, selective openings or special locking mechanisms.

↑Go to Top


(5) Advanced Strategies

(i) Air Earth tunnels

neemrana

A 16 km (once campus completed) tunnel network of Air Earth tunnels, will be running 4 m below the ground in NIIT University, Neemrana Campus. Surface temperature and seasonal variations do not penetrate below this depth, keeping air temperature constant throughout the year. Fans will pull cool air through these tunnels. This would then be taken through precipitators to eliminate dust and would be supplied to the building through ducts. The result! – Pleasant 25oC temperatures indoors, without the use of air-conditioning, when temperatures outside are nearing 50oC5.

(ii) Wind Tower

These are utilized widely in desert climates (eg. Iran, Saudi Arabia). Tall towers are built with openings facing the prevailing wind direction. The openings are narrow and the towers may contain misters or other moisture creating devices. As the tall tower catches winds, air moves down the tower, cooling on the way and is used in the building. A similar system using Shower Towers is used at DPR Office, Phoenix.

(iii) Stack effect

According to the principle, warm air from an area would rise, making space for cooler air. This would generate a loop of air circulation. This effect can be seen at building scale or even at room level. In Indira Paryavaran Bhavan, the central courtyard spine coupled with well placed building punctures, generates the ‘Stack Effect’ at the building scale. The IRRAD Building, although using air-conditioning, is utilizing a similar principle. The vents are placed near the floor, instead of the ceiling. Cool air enters the room at a lower level and it rises as it become warm6.

(iv) Displacement Ventilation

In Neemrana University, the cool air from ducts is introduced at lower levels in rooms. This pushes warm air in the room upwards, which is then exhausted through openings in higher parts of the spaces. It is similar to the stack effect, but here an additional push is being provided by the introduced cool air, to get the circulation loop going.

(v) Wind Scoops

Wind Scoops like the one used in CapitaGreen can channel air into a ‘Cool Void’. This brings cool air from a higher altitude, deeper into a high-rise building. Air flow, such as that channeled by CapitaGreen maybe blocked by surrounding buildings in a different scenario.

Solution | City Planning and Studies – This leads to the need for city planning and studies like Computational Fluid Dynamics (CFD) to ensure these strategies are workable at a city level. This would help avoid “dead air zones”, wind canyons and other undesirable wind related events. This becomes especially important in city centers with greater density and multiple high-rise structures.

(vi) Solar Chimney

The DPR Phoenix Regional Headquarters in Pheonix, Arizona use solar chimneys to exhaust warm air from the building.

(vii) Evaporative cooling

This technique utilizes the latent energy used to convert liquid to gas. As water evaporates, its phase changes, which results in a cooling effect. This technique has been used widely in desert coolers.

That’s all for this week. Hope this was useful! As always, please let us know your thoughts, suggestions, queries, opinions. Your views will make this exploration richer!

Thank you!

LEED AP BD+C: Resources and Materials (Free)

LEED ram f

(Updates below)

This is part of a series of articles on the experience of giving the LEED AP BD+C examination. Last week we completed our 2-part article on 11 Essential ‘Need-To-Knows’ before LEED AP BD+C Prep (Part 1, Part 2). Now, we start to look at Resources and Materials (both Freely available and Paid) that would be useful for this preparation.

This week we start with Freely available online resources. Based on your level of experience and knowledge, you may be able to pass the exam by using just the free resources. Some of our team however, felt the need for additional support. So, they made use of some ‘Paid’ resources which we talk of next week in case you feel the need for those.

Note: We have employed exhaustive online research, to explore all possible sources on the topic, as we felt that relying on any one source may not be enough.

Our articles are not endorsing any online courses/ question banks. However, we would like to give due credit to pages that our team found useful while attempting the exam. Ultimately, it is totally up to your choice and discretion whether to subscribe to them.

  1. Online Book
  2. Other Resources
  3. Practice Questions
    • USGBC
    • GBRI
    • Everblue

1) Online Book

  • Latest Link – This is a 160+ pages free Document that has everything you need to know for the exam. The latest update to the book was published by USGBC on 2nd July 2018. The link for this PDF is here.
  • Updates – We will keep updating this link. If at some point you are unable to access it, that could mean that USGBC has published another update and removed the earlier version. Just google LEED v4 BDC pdf and you should be able to find an org link saying current version.
  • Getting through the book – If you can get through this slightly intimidating document on your own, then you may not need to refer to other sources at all. If however, the thought of reading and getting through the first page onward is a little daunting, you could try a couple of different methods and resources (explained below and in ‘Method of Study’ in coming weeks).

Also known as Conserve Academy, this is an excellent resource that we talk about in detail later. This is a paid resource, but Introduction videos and few chapters like ‘Location and Transportation’ for LEED AP BD+C are available for free.

  • Video for Location and Transportation Credit – Sensitive Land Protection
  • Video for Location and Transportation Credit – High Priority Site
(d) Poplar

This is a 27-page slideshow about useful LEED concepts.

(e) Quizlet

This application allows students to learn using tools and games. We had heard about this website and thought to give it a try. Searching for LEED AP BD+C gives a massive list of flashcards with useful terms to study for the exam. This material is created by users from around the world. It can offer a unique perspective and can be good for revision reading towards the later stages of preparation.

(f) GBES

Update: We recently found another free resource. A glossary of 257 v4 terms presented in Excel format. The file also includes translations in other languages like Portuguese, Spanish, Chinese, Arabic, Italian.

(g) GreenCE

Update: While writing our article on Paid Resources, we came across this section on FREE courses offered by GreenCE. The courses are meant for collecting Continuing Education hours once you have passed the examination. However, these can be referred to earlier, during exam preparation as well. Since they refer to actual projects applying LEED Credits, they are very useful in understanding the certification process. There are General and Specific courses (BD+C, Homes, ID+C, O+M, ND).

6) Questions and Time Limit

(i) 2 hours, 100 questions

(ii) As mentioned in the first post, the questions are longer (than LEED Green Associate) and include more detail. You will need to quickly sift out relevant bits to answer the questions.

↑Go to Top


7) Format of questions

(i) Questions are multiple choice.

(ii) There can be one choice or multiple choices as answers. (The exam will specify for each question whether it needs a single answer or more.)

(iii) During the exam, you can attempt, skip, mark questions (to come back to later), or leave comments for your reference.

↑Go to Top


8) Minimum score and Marking System

(a) Minimum Score

You need to score a minimum of 170 out of 200.

(b) Marking

(i) The Green Business Certification Inc. (GBCI) marking system is unique. You cannot assume that if you answer 85 questions correctly, then you pass (That is, each question is not allotted 2 marks uniformly, which would mean 85 X 2=170).

(ii) 15 questions (of the 100) are not marked. They are only for evaluation purposes.

(iii) The remaining questions have the marks divided amongst them based on specific criteria such as difficulty level, application etc.

(iv) There is no negative marking! (Thank the Universe!!) You can safely attempt all questions.

↑Go to Top


9) Calculations

(i) There are (basic) calculations involved in this examination.

(ii) You will have access to an inbuilt calculator on the exam screen.

(iii) In addition to this, you will be provided with a marker and sheet to do written calculations.

↑Go to Top


10) Some memorizing required

This exam expects you to be trained enough to be a LEED AP BD+C professional. Consider this example – If you’re a doctor, you need to know various symptoms, their causes, preliminary treatments etc. off the top of your head. When your patients consult you, you can’t go around rummaging through notes and handbooks to give an answer. Well here you’re not a doctor, but still training to be a professional. So, we feel the same rules are applicable.

11) USGBC Help

We have tried to mention all relevant ‘Need-To-Knows’, before starting LEED AP BD+C prep. You may have additional queries. You could leave a comment, contact us here, or refer to the USGBC help page. The USGBC page is a wonderful resource with many pre-answered questions. You can also ask them a question, if you feel, your query has not been covered in this section.

This is a useful 26-page document, that you must read before everything else! In short it talks about the following things –

    1. Registration basics and eligibility requirements, fees and other special conditions
    2. Exam format, language, updates
    3. Important documentation, test center regulations and general rules
    4. After exam results, certificate, appeals

2) Exam Fees

(a) LEED Green Associate – $ 250
(b) LEED AP BD+C – $350
(c) Combined Examination – $550

It is cheaper to give the combined exam which would mean both exams happen on the same day. However, we would strictly recommend against this option for 2 reasons –

(i) If you pass the first paper and not the 2nd, then you cannot even call yourself a LEED Green Associate. Since you’ve applied to become a LEED AP (Accredited Professional), you need to pass both exams (Check out FAQ No. 2 here)

(ii) Both Green Associate and AP BD+C although working towards the same goal, require different types of preparation. While Green Associate is more of an introductory exam, AP BD+C needs more in-depth knowledge and practice. Attempting them together would be strenuous and might prove counter-productive.

3) Requirements, Prior Knowledge

(a) Mandatory Requirements

(i) You need to have passed the LEED Green Associate examination to be eligible to give the LEED AP BD+C exam. (We are referring to the standalone LEED BD+C exam – fees $350.)

(ii) You also must be 18 years of age or older.

(b) Recommendations

(i) GBCI recommends that you should have prior LEED project experience before attempting the examination.

(ii) It helps if you have some Architectural knowledge or experience, or anything to do with Construction, Sustainability or the Environment. You can of course still give the paper without this background, but that might need more preparation time and could be a harder learning curve.

4) Registration

(a) Account

Create an account on the USGBC website (if you have passed LEED Green Associate, you would already have an account).

(b) Credentials

Go to Credentials

(c) Registration

(i) Choose the BD+C exam, register and make payment (Make sure you enter your details carefully).

(ii) After registration, you have 1 year to pass the exam. This registration could be extended by 6 months on request by contacting GBCI.

(iii) Within the registration period, you get 3 attempts to pass the exam. Each fresh attempt needs to be paid for.

(iv) If you are unable to pass in 3 attempts, you need to wait 90 days, before registering again.

↑Go to Top


5) Scheduling

Prometric

(a) Prometric Centre

After registration, you schedule the exam on the Prometric website. Find the center closest to your location, choose the best date and time available and book a sitting. (Choose a slot that suits you, when your mind works best!)

(b) Alternate Exam Delivery

Recently another option called Alternate Exam Delivery (AED) has been started, where exams can be scheduled as a group in familiar surroundings outside of Prometric centers.

The LEED Experience

A series of Articles on the experience of the LEED BD+C examination.

This article is written by our contributing Author – Aditi Bisen.


The LEED AP BD+C (Accredited Professional – Building Design + Construction) is a useful professional credential to add to your Resume. Apart from its global recognition, it prepares individuals to handle a wide breadth of issues related to Building Design, Construction and Sustainability. Some of our writers attempted and passed the LEED AP BD+C examination with high scores (190+ out of 200). We decided to pool their understanding and resources to write a series of articles on the LEED Experience.

These articles are assuming that readers have already given the LEED Green Associate examination (This is an introductory exam, that in most cases needs to be passed before one attempts the LEED AP BD+C). We will later try and write a series on LEED Green Associate.

We will be using the following post series order for articles. Hope these are useful!


4 reasons why LEED AP BD+C was a difficult cookie to crack!

hunger-413685_1920

1) 85% 

You need a minimum of 85% (170 / 200) to pass the examination!! This is a tall order.

2) Heavier load in 2 hours 

Unlike in LEED Green Associate, there are calculations involved. The questions are longer and more detailed, while you still get 2 hours to attempt 100 of them. This is taxing and requires planning and practice.

3) LEED Specific Experience 

Our writers had Architectural or Sustainability backgrounds, but almost no experience on LEED Specific Projects. Green Business Certification Inc. (GBCI) recommends that you should have prior LEED Project Experience before attempting the examination. If you have this experience, things become relatively easier, since the questions are effectively asking you how you worked on the projects.

4) Expense of resources 

The complete Reference Guide for LEED AP BD+C costs $200. Many people either didn’t want to, or could not afford to buy this Guide. This was a risk, since their preparation could be incomplete. However, they were able to achieve good scores using alternative materials provided by USGBC and other websites.

E@BS 4/5: Residential – Skyville@Dawson

This is Segment 4 of our Chain of posts focused on ‘Energy @ the Building Scale’.
[Extension of Part 4/5: The Red System (Energy), Singapore – Published: 28th May 2018]

clusters editted
Plan diagrams showing Apartments Clusters

Skyville@Dawson is a 111,106 sq.m., 48-storey1 public housing project by WOHA Architects in Queenstown, Singapore. It is one of two Build-To-Order (BTO) projects commissioned by Singapore’s Housing Development Board (HDB), as part of their “Remaking Our Heartland” initiative (the other being SkyTerrace@Dawson by SCDA Architects)4. This “housing-in-a-park” concept would show transferability in future projects and towns like – Waterway Terraces, Bidadari, Punggol Northshore, Tampines North6. It is the first housing development to be awarded the GreenMark Platinum Rating10. Skyville@Dawson’s Sustainable Design features including Passive Strategies are elaborated below-

Contents

  1. MASSING AND CONFIGURATION
    • Orientation
    • Clustering and Modules
  2. FORM, DAYLIGHT, VENTILATION
    • Unit Thickness
    • Breathability – Horizontal Air Movement
    • Breathability – Vertical Air Movement
  3. INTEGRATION WITH GREEN AND BLUE
    • Horizontal Green
    • Site Integration with Green and Blue
  4. BUILDING ENVELOPE

1) MASSING AND CONFIGURATION

Orientation

(i) The Building is placed with its longer facades facing the North-South9 directions. This reduces exposure to the East and West directions, that are normally difficult to shade.

shadow studies
Shading Studies for Skyville@Dawson

Clustering and Modules

(i) 8 apartments in plan(as seen in Plan diagrams above), surround a courtyard. This cluster is repeated 2 more times, to create 3 sets of apartments enclosing courtyards. This configuration also provides self-shading, especially from low angle rays from the East and West directions (as seen in the Shadow Studies above).

(ii) In Elevation, 12 clusters form villages, each comprising of 80 apartments.

Perspective diagrams showing Apartment Villages

(iii) The apartment layouts are column and beam free4. This provides the possibility of 3 layouts for residents – reducing wastage, allowing flexibility for multiple functions, family size and the future.

(iv) For standardization, efficiency and to reduce wastage, only 5 window types2  have been used in the entire development.

(v) The design uses precast and prefabricated10 elements to avoid errors and reduce wastage. This feature could also contribute towards LEED BD+C v4 CreditConstruction and Demolition waste management.

2) FORM, DAYLIGHT, VENTILATION

Unit Thickness

(i) The individual apartments are approximately 11 meters across in width, thus applying the Unit Thick Principle. Apartments also have openings in all directions. They are thus naturally ventilated and day lit, reducing artificial cooling and lighting costs.

Plan diagram showing Unit Thick apartment blocks

Breathability – Horizontal Air Movement

(i) The clustering arrangement around courtyards, and the repetition of this module linearly, enables horizontal air circulation.

Plan diagram showing Horizontal air movement through courtyards and building block gaps

(ii) Common areas (Lobbies, Corridors, Staircases) and Apartments are naturally ventilated. Many units have not installed Air-conditioning3.

Breathability – Vertical Air Movement

(i) With minimal obstructions and the creation of Canyon like spaces, air moves vertically through the towers – accentuating the breezy atmosphere. The interaction of this air with greenery from sky gardens at intermediate levels, cools this air through evapotranspiration.

3) INTEGRATION WITH GREEN AND BLUE

Horizontal Green

(i) ‘Sky Terraces’7 are located every 12 floors. These are designed as community spaces, where people can collect to interact with neighbors or simply visit to relax and enjoy the lush greenery.

hori greenery
Sky Gardens and Rooftop Garden

(ii) A ‘Sky Park’7 on the roof has planters, hedges, and beautiful city views. Photovoltaics3 power the common area lighting.

Site Integration with Green and Blue

(i) A 150 m long bio-swale (gently sloping ditch with specific plants) filters and treats site stormwater before discharging it into the city drainage system5. Another example of a bio-swale – water treatment and recycling loop can be seen in Kampung Admirality.

Site Plan diagram showing location of Parks, Plaza and Bio-swale

(ii) The site is an ungated3 community, with Public Parks and Amenities that cater to the residents as well as the general public.

 ↑ Go to Contents ↑


4) BUILDING ENVELOPE

(i) Monsoon windows8 on the facade can be kept open during rains, thus providing cool breeze without wind-blown rain entering the home. A similar more advanced Monsoon Window design is utilized in another high-rise residential building – 1 Moulmein Rise, Singapore.

(ii) The walls on the facade have horizontal and vertical sunbreakers5. Balconies or horizontal ledges9 are used to provide shading for openings.

(iii) Double-height verandas10 on the ground level provide pleasant public spaces overlooking the parks.

Addressing East and West Facades

Sustainable Snippets

These faces of the building are difficult to shade, as they receive low angle rays from the rising and setting sun. Common shading features such as horizontal projections, usually fail in such situations. Our 3 case-studies explain methods to address these tricky areas of the building.

ss1
Addressing East, West Facades; Graphics: Credits below
  1. Park Royal – The East, West facades are shaded using self-shading, achieved due to the E-shape projections from the Plan.
  2. CapitaGreen – Of all the vertical green on the facade, larger amount of greenery is provided on the East, West facades to shade them.
  3. Cleantech One – Sky gardens and planters on these facades help cool the labs and create pleasant breakout spaces.

Q & A – 1

We believe that asking Questions drives Research and Innovation. We will strive to keep questioning, to arrive at practically applicable Design that could affect meaningful change!

We interrupt the ongoing Chain of posts on E@BS to introduce our ‘Q & A’ column. Our segment on Cleantech One, left us with 2 questions. We address one of them today –

Question)

Integration with Green has positive effects on micro-climate and energy loads. However, landscaping has associated water and maintenance costs. There are also issues of insects that may not always be welcome in an urban/ strictly controlled setting like that of laboratories. What do you think about this?

Update: You could now also watch our video about ‘Building with Nature‘ in the ‘Sustainable Snippets‘ or ‘TAG Videos‘ sections. Hope you enjoy it.
