Here at ComputingPost, we like exploring various network and system monitoring tools. So far we have covered the basic setup and usage of Zabbix, telegraf/InfluxDB, Grafana, and Prometheus. Zabbix functionality is similar to Cacti, though Cacti is more fit for network graphing. In this guide, we’ll look at how to install and configure Cacti on Ubuntu 20.04|18.04 Linux server. What is Cacti? Cacti is a completely open-source network monitoring and graphing tool that was designed as a front-end application for the industry-standard data logging tool RRDtool. Cacti harness the power of RRDTool’s data storage and graphing functionality. Some good features of Cacti include: Fast polling of metrics Support for multiple data acquisition methods Support for advanced graph templating User management functionality with ACL Cacti provide an intuitive and easy to use web interface which can be used for small LAN installations up to complex networks with thousands of servers and networking devices. Install Cacti Server on Ubuntu 20.04/18.04 Cacti has a number of dependencies that need to be installed and configured before you can deploy Cacti server itself. This guide will cover the installation of these dependencies one by one: Step 1: Update system and upgrade all packages We always start with server packages upgrade to avoid any dependency issues: sudo apt update sudo apt upgrade -y You can reboot the server after upgrade: sudo reboot Step 2: Install php and required modules We now need to install php and some php modules required by cacti. Run the following commands to get everything and installed. sudo apt -y install apache2 php php-mysql,curl,net-socket,gd,intl,pear,imap,memcache,pspell,tidy,xmlrpc,snmp,mbstring,gmp,json,xml,common,ldap sudo apt install libapache2-mod-php The most important module is php-snmp and php-mysql. Make sure they are installed. You can check your php version using the command: $ php -v PHP 7.4.3 (cli) (built: Nov 25 2021 23:16:22) ( NTS ) Copyright (c) The PHP Group Zend Engine v3.4.0, Copyright (c) Zend Technologies with Zend OPcache v7.4.3, Copyright (c), by Zend Technologies Update PHP parameters: sudo vim /etc/php/*/apache2/php.ini Set correct timezone: date.timezone = "Africa/Nairobi" Update memory limit: memory_limit = 512M Also adjust Maximum execution time of each script: max_execution_time = 300 Restart Apache Web server Step 3: Configure Apache Web server Ensure Apache web server is installed: sudo apt install apache2 After installing Apache, configure basic security by allowing Prod ServerTokens only. sudo vim /etc/apache2/conf-enabled/security.conf Change line 25 ServerTokens Prod This directive configures what you return as the Server HTTP response. Valid options are Full | OS | Minimal | Minor | Major | Prod. Set ServerName: $ sudo vim /etc/apache2/apache2.conf ServerName cacti.example.com Set Server Admin to receive an email in case of issues. $ sudo vim /etc/apache2/apache2.conf ServerAdmin [email protected] If you have ufw enabled, open http and https ports on the firewall. $ sudo ufw allow http Rule added Rule added (v6 $ sudo ufw allow https Rule added Rule added (v6) You need to restart apache web service after making these changes: sudo systemctl restart apache2 Step 4: Install and Configure MariaDB Database Run the following commands to install MariaDB server on Ubuntu:s sudo apt install mariadb-server -y Tune MariaDB database for Cacti Add the following settings under [mysqld]: $ sudo vim /etc/mysql/mariadb.conf.d/50-server.cnf [mysqld] innodb_file_format=Barracuda innodb_large_prefix=1 collation-server=utf8mb4_unicode_ci character-set-server=utf8mb4 innodb_doublewrite=OFF max_heap_table_size=128M tmp_table_size=128M join_buffer_size=128M innodb_buffer_pool_size=1G innodb_flush_log_at_timeout=3 innodb_read_io_threads=32 innodb_write_io_threads=16 innodb_io_capacity=5000 innodb_io_capacity_max=10000

innodb_buffer_pool_instances=9 Comment out other settings on local #around line 116 #character-set-server = utf8mb4 #collation-server = utf8mb4_general_ci Restart mariadb service sudo systemctl restart mariadb To check any of these settings, use mysql select statement, e.g. $ sudo mysql -u root MariaDB [(none)]> select @@tmp_table_size; +------------------+ | @@tmp_table_size | +------------------+ | 134217728 | +------------------+ 1 row in set (0.00 sec) MariaDB [(none)]> exit Bye Or MariaDB [(none)]> show variables like 'join_buffer_size'; Once Database server installation is done, you need to create a database for Cacti: $ sudo mysql -u root -p CREATE DATABASE cacti DEFAULT CHARACTER SET utf8 COLLATE utf8_unicode_ci ; GRANT ALL PRIVILEGES ON cacti.* TO 'cacti_user'@'localhost' IDENTIFIED BY 'strongpassword'; GRANT SELECT ON mysql.time_zone_name TO cacti_user@localhost; ALTER DATABASE cacti CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci; FLUSH PRIVILEGES; EXIT; Test database connection: $ mysql -u cacti_user -p Enter password: strongpassword MariaDB [(none)]> show databases; +--------------------+ | Database | +--------------------+ | cacti | | information_schema | +--------------------+ 2 rows in set (0.00 sec) MariaDB [(none)]> \q Setup mysql timezone for cacti database user $ sudo su - $ mysql_tzinfo_to_sql /usr/share/zoneinfo | mysql -u root -p mysql Enter password: Warning: Unable to load '/usr/share/zoneinfo/leap-seconds.list' as time zone. Skipping it. Step 5: Install SNMP and Cacti on Ubuntu 20.04/18.04 The last package installation step is for Cacti and snmp packages. Cacti depend on Snmp and rrdtool tool for its functions. Install these packages using the command: sudo apt install snmp snmpd snmp-mibs-downloader rrdtool When asked to select the web server, choose Apache. Clone Project from github: $ sudo apt install git $ git clone -b 1.2.x https://github.com/Cacti/cacti.git Cloning into 'cacti'... remote: Enumerating objects: 75698, done. remote: Counting objects: 100% (1608/1608), done. remote: Compressing objects: 100% (496/496), done. remote: Total 75698 (delta 1155), reused 1536 (delta 1105), pack-reused 74090 Receiving objects: 100% (75698/75698), 127.92 MiB | 7.02 MiB/s, done. Resolving deltas: 100% (56327/56327), done. Updating files: 100% (3621/3621), done. After cloning the Cacti repository, move the files into the /var/www/html directory: sudo mv cacti /var/www/html Let’s now pre-populate the database used by cacti: sudo mysql -u root cacti < /var/www/html/cacti/cacti.sql With the database populated we can go ahead and create the config.php file in /var/www/html/cacti/include: sudo mv /var/www/html/cacti/include/config.php.dist /var/www/html/cacti/include/config.php Modify Cacti configuration file and make sure to change the database settings as needed: $ sudo vim /var/www/html/cacti/include/config.php $database_type = 'mysql'; $database_default = 'cacti'; $database_hostname = 'localhost'; $database_username = 'cacti_user'; $database_password = 'strongpassword'; Step 6: Configure SNMP Start by enabling the loading of MIBs by commenting out the following line on /etc/snmp/snmp.conf sudo vim /etc/snmp/snmp.conf Change mibs : to # mibs : Configure SNMP community name by editing /etc/snmp/snmpd.conf sudo vim /etc/snmp/snmpd.conf Enable full access from localhost: rocommunity MyCacti localhost Disable public access by commenting below lines: rocommunity public default -V systemonly rocommunity6 public default -V systemonly To # rocommunity public default -V systemonly # rocommunity6 public default -V systemonly Restart snmpd service: sudo systemctl restart snmpd Validate snmp configurations using snmpwalk command line tool: $ sudo snmpwalk -v 2c -c MyCacti localhost system SNMPv2-MIB::sysDescr.0 = STRING: Linux ubuntu 5.4.0-73-generic #82-Ubuntu SMP Wed Apr 14 17:39:42 UTC 2021 x86_64 SNMPv2-MIB::sysObjectID.0 = OID: NET-SNMP-MIB::netSnmpAgentOIDs.10

Meanwhile, in AI-ethics land

https://ainowinstitute.org/AI_Now_2019_Report.pdf

(...)

2.1 The Private Automation of Public Infrastructure

As attention to the concerns about AI infrastructures increases, we tend to see them discussed in terms of a dichotomy between public and private uses. This separation has always been false on some level and this year we have seen signs of its eventual collapse, with clear evidence of ongoing and expansive integration of public and private systems across many different AI domains.

AI and Neighborhood Surveillance

Troubling partnerships between government and private tech companies also emerged as a trend this year, especially those that extended surveillance from public environments into private spaces like private properties and the home.

For example, this summer, a Canadian RCMP troop in Red Deer, Alberta, launched a program called CAPTURE to enable “community assisted policing through the use of recorded evidence.”252The idea was for commercial businesses and personal residences with private security-camera infrastructure to effectively share the captured information on their private property with the police, under the guise of improved community safety. As of November, more than 160 properties are participating, effectively covering the entire map of the city, and providing access to the police surveillance of spaces previously inaccessible without a warrant and consent for entry.253 Since 2016, Project Green Light in the City of Detroit in the United States has been working in an almost identical fashion. By March of 2019, the mayor of Detroit decided to establish the “Neighborhood Real-Time Intelligence Program,” described as “a $9 million, state- and federally-funded initiative

AI Now 2019 Report page 36

that would not only expand Project Green Light by installing surveillance equipment at 500 Detroit intersections—on top of the over 500 already installed at businesses—but also utilize facial recognition software to identify potential criminals.”254

Amazon exemplified this new wave of commercial surveillance tech with Ring, a smart-security-device company acquired by Amazon in 2018. The central product is its video doorbell, which allows Ring users to see, talk to, and record those who come to their doorsteps. This is paired with a neighborhood watch app called “Neighbors,” which allows users to post instances of crime or safety issues in their community and comment with additional information, including photos and videos.255 A series of reports reveals that Amazon had negotiated Ring video-sharing partnerships with more than 700 police departments across the US. Partnerships give police a direct portal through which to request videos from Ring users in the event of a nearby crime investigation.256 Not only is Amazon encouraging police departments to use and market Ring products by providing discounts, but it also coaches police on how to successfully request surveillance footage from Neighbors through their special portal.257 As Chris Gilliard, a professor who studies digital redlining and discriminatory practices, comments: “Amazon is essentially coaching police on . . . how to do their jobs, and . . . how to promote Ring products.”258

Neighbors is joined by other apps like Nextdoor and Citizen, which allow users to view local crime in real time and discuss it with one another. Ring, Nextdoor, and Citizen have all been criticized for feeding into existing biases around who is likely to commit crime; Nextdoor even changed its software and policies given extensive evidence of racial stereotyping on its platform.259 Others see these app-based surveillance operations sowing a climate of fear, while tech companies profit from a false perception that crime is on the rise.260

Smart Cities

Concerns about the privatization of public space took center stage this year in the debate around “smart cities” (municipalities that use data, sensors, and algorithms to manage resources and services).

Most smart-city initiatives rely on public-private partnerships and technology developed and controlled by tech companies, which shifts public resources and control over municipal infrastructure and values to these companies.261 Recent research has exposed the extent to which major tech companies such as IBM and Cisco have been “selling smartness” by disseminating narratives about urban challenges and technological solutions to those challenges.262 The Alphabet company Sidewalk Labs has similarly been producing vision documents replete with renderings of utopian urban scenes.263 These companies see the potential for massive profits: one report estimated the global smart cities market being worth $237.6 billion by 2025.

Smart-city projects around the United States and the world increasingly consolidate power in the hands of for-profit technology companies, while depriving municipalities and their residents of resources and privacy. The highest-profile example is in Toronto, the home of Sidewalk Lab’s project to develop “the world’s first neighbourhood built from the internet up.”265 A report in February 2019 found that Sidewalk Labs has expressed a desire to receive a portion of the property taxes and development fees (estimated at $30 billion over 30 years) associated with the project, which would otherwise go to the City of Toronto.266 And in June 2019, Sidewalk Labs released a Master Innovation and Development Plan (MIDP), describing plans to develop and manage a far larger plot of land than the 12 acres for which the company was initially given license to develop plans.267

Smart-city projects also lack transparency and genuine forms of civic participation.268 Sidewalk Labs’s civic engagement efforts have been described as a process of obfuscation and “gaslighting.”269 Similarly, a contract between urban-planning software company Replica (a Sidewalk Labs spinoff company) and the Portland, Oregon regional transportation planning agency provides no public access to Replica’s algorithms.270 Siemens is launching a €600 million smart-city neighborhood in Berlin, creating “laboratories in reality” with barely any public meetings so far.271

Many of these public-private partnerships directly enhance the government’s surveillance capabilities. Chicago and Detroit have both purchased software enabling them to deploy facial recognition in the video feeds from cameras across the cities.272 Similarly, the multinational Chinese tech company Huawei’s $1.5 billion project to create smart cities in Africa273 included a project in Nairobi where it installed 1,800 cameras, 200 traffic surveillance systems, and a national police command center as part of its “Safe City” program.274 Huawei’s Safe City technology has been used by some African governments to spy on political opponents.275

In other cities, behind-the-scenes data-sharing arrangements allow data collected by private companies to flow into law-enforcement agencies. San Diego has installed thousands of microphones and cameras on street lamps in recent years in an effort to study traffic and parking conditions; although the data has proven of little use in improving traffic, the police have used the video footage in more than 140 cases without any oversight or accountability.276 The City of Miami is actively considering a 30-year contract with Illumination Technologies, providing the company with free access to set up light poles containing cameras and license-plate readers, collecting information that will filter through the Miami Police Department (and that the company can use in unchecked ways).277 Documents obtained via public-records requests showed that 300 police departments in California have access, through Palantir, to data collected and stored by the Department of Homeland Security’s Northern California Regional Intelligence Center, without any requirement to disclose their access to this information.278

Numerous groups are beginning to push back on the encroaching privatization fueled by smart cities, with the most concerted and organized effort in Toronto. In February, a group of 30 Torontonians launched the #BlockSidewalk campaign,279 and has noted that the project “is as much about privatization and corporate control as it is about privacy.”280 In April, the Canadian Civil Liberties Association (CCLA) filed a lawsuit against Waterfront Toronto, arguing the organization abused its legal authority in granting Sidewalk Labs the authority to develop data-governance policy.281 And after Sidewalk Labs released its MIDP, the Chairman of Waterfront Toronto (the government task force charged with managing the Sidewalk Labs project) critiqued the proposal in a public letter as “premature.”282

By the end of October, Waterfront Toronto had reached a new agreement with Sidewalk Labs, restricting Sidewalk Labs to the original 12-acre parcel and asserting the government’s role as leading key components of the project.283 The project’s ultimate fate is still undetermined: Waterfront Toronto continues to review the project and will come to a final decision about whether to proceed by March 31, 2020.284

How Ngei Estate completely eliminated insecurity

If you do not feel safe, no matter where you live, you will not be a happy tenant. Even if you live in a leafy neighbourhood that has running water all day-long, has a sewerage system that works, or is near amenities such as schools, hospitals and one-stop malls, if you do not feel secure when you go to sleep at night, you will be a dissatisfied homeowner.

Several years ago, residents of Ngei Phase II in Nairobi’s Lang’ata area lived in apprehension. Robbery and theft, even in broad daylight, was common until the residents came together, pooled resources and took deliberate measures to ensure that they and their families were safe.

The chairperson of the residents’ association, Mr Paul Murwithania, offers lessons on how residents can improve the safety in their neighbourhoods. Mr Murwithania is a security expert and a former senior criminal investigations officer who currently works for an international organisation in charge of security and safety.

The estate, he explains, is made up of a church, several schools and 298 main houses. Many of these houses also include extensions and servant quarters.

The chair, who moved into the estate in 2006, says that the estate was once a hotbed of crime. Burglaries and car break-ins, he says, were especially common.

“You would park your car at your front gate and get into your house, but on getting out a while later, you would find a wheel or other accessories missing,” he says, adding that incidents of crime are now unheard of.

From experience, he says that the first step in combating neighbourhood crime is to get every resident’s support. “Keeping our estate safe is an undertaking that required a lot of money as well as goodwill from the residents. While every resident agreed that security was important, it was not easy to convince them to dutifully contribute the monthly membership fees we had agreed on,” he reveals.

Rose Mwangi, a resident of the estate since 2007, says that the executive committee of the estate, which is tasked with running the neighbourhood’s affairs had to prove to the residents that the money collected would be put to good use.

“We implemented a strategy whereby we release quarterly financial reports to show our members how their money was spent. We also introduced digital payment to make tracking of payments easier. This has greatly increased compliance,” says Ms Mwangi, who serves as the secretary to the estate’s executive committee.

Having seen the ways in which their money has been utilised, some members of the estate now go an extra mile and volunteer their time resources to keep the neighbourhood safer.

Says Murwithania, “Sometime back, part of the estate’s fence was damaged, and people that don’t live here began to sneak into the main playground to, ostensibly, play football, but were actually peddling drugs such as bhang in the estate. We raised money and put up a fence, which immediately dealt with this problem,” he says, adding that any outsiders hiring the ground for events are duly vetted.

Ensuring that the residents follow the rule of the law, no matter their status in the estate, was another critical step in bringing security to Ngei Phase II.

For example, residents are prohibited from ordering deliveries past 10pm, and all are required to have their vehicles inspected by security personnel. Also, no resident is allowed to put up an unapproved structure as had been the norm before, a factor that led to formation of informal settlements around the area.

Ms Mwangi explains that earlier on, private developers had grabbed land that was supposed to be used by the residents as a playground.

“Informal kiosks had been built on our playground and a slum had formed right inside the neighbourhood. This posed a great security risk. When we finally gathered the courage to demolish the slum, the dwellers simply put up new shanties along the fences of our estate. It took a lot of push and pull, but we finally managed to keep the shanties away,” she says.

Although hiring and training security guards came at an extra cost to the residents, Murwithania says that it was a worthy investment.

“We have a number of guards who man our two gates to make sure that only bonafide residents and their visitors are granted access into the compound. All registration numbers of vehicles entering the estate are recorded, and visitor’s particulars taken down with all daily casual workers required to leave their identity cards at the entry points and collect them after their visit. Keeping idlers away from the estate is a crucial step in ensuring that residents feel safe. The guards also patrol the compound at random intervals,” he explains.

But just hiring security personnel is not enough. The guards need to be in uniform, but above all, well paid and have their welfare taken care of. A happy security guard, Murwithania says, does his job with enthusiasm and is more diligence. The estate has also built the day and night guards offices and living and relaxation areas.

A strong relationship with the police has certainly helped matters. The chair says that they work closely with Langata Police Station, and their officers carry out night patrols in the estate. The property, being located near Lang’ata Barracks, is home to several senior police officers and members of the armed forces, who volunteer their expertise in keeping the neighbourhood safe.

“We are also beneficiaries of a CCTV camera project installed last year by Safaricom in partnership with Kenya Alliance of Residents Association. I can now monitor what is happening within the estate on my mobile phone and supervise the guards even when I’m out of town,” Murwithania says.

Keeping your streets well lit at night is another important step in enhancing security.

“Three years ago, the World Bank and the Nairobi City County installed security lights all around the estate. Residents are no longer afraid of staying up late, in fact, we feel so safe, once in a while we have night-parties along the well-lit sidewalk,” says Murwithania.

Creating social bonds among the residents has also led to a more secure environment since neighbours know each other and feel motivated to look out for each other.

“I try my best to bring the residents together so that they can bond and develop trust among one another. We, for instance, encourage zonal courts to host regular parties where they can sit down together and exchange ideas on how to improve our neighbourhood. We also have WhatsApp groups in which we share our security concerns,” he says.

This is not all. In the future, the estate plans to build a clubhouse that will host a gym and a shopping complex that will also serve as a meeting point for the residents.

There are also plans to put a car washing bay for the youth in the estate, a business from which they can earn money and also spend their time constructively.

There are a couple of challenges that the estate is grappling with, however. One is dilapidated roads that were last rehabilitated in the 1970s. Water, too, is a pressing issue with residents sometimes receiving water only once a week.

“We have done our part and taken care of security, besides lobbying the Nairobi County government to look into these issues, there is little else we can do,” he says, hoping that the matter will be sorted out soon.

SABIS International School Runda in Nairobi, Kenya

Concept design architects: Archika Executive architects: Boogertman + Partners

SABIS International School – Runda, Nairobi, sets a regional precedent

The new SABIS® International School – Runda in Nairobi achieved a 4-Star Green Star Africa-Kenya PEB v1 Design Rating in April 2020. The school is being presented as a case study at the World Green Building Week (21-25 September), and a tree-planting ceremony is being planned as part of the Green Star design certificate handover process.

SABIS® International School – Runda offers a world class education to students from kindergarten to Grade 12 within a vibrant, multicultural community that is committed to academic excellence. Construction on the state-of-the-art campus, which gives students the space to learn, grow and discover their talents, started in June 2016 and was completed in June 2018.

Facilities include an independent kindergarten area, upper and lower school buildings, cafeteria, gymnasium, pool, football pitch, tennis courts, mini car track, and an auditorium. As the first Green Star certified school in Kenya, the aim was to positively impact the project’s design and construction costs, asset value, operating costs, workplace productivity and user health.

With a GFA of almost 14,600 sqm, the school is conveniently located near the Northern Bypass in Kiambu County. The project was developed by the SABIS® Network, a global network of schools that dates back to 1886 and currently educates over 70,000 students in 20 countries on 5 continents. Concept design architects on the project were Archika, with Boogertman + Partners as executive architects. The green building AP (accredited professional) team comprised WEB Limited, a Kenyan based sustainable development consultancy and co-founding member of the Kenya Green Building Society, in collaboration with Solid Green Consulting.

Urban & Climatic Context

Elizabeth Wangeci Chege of WEB Limited explains that the site was chosen to meet growing demand for a new school in an area that has become densely urbanised in the last 10 years. Being very close to the Equator with no extremes in weather, conditions lent themselves to passive design; the soil is conducive to plant growth and biodiversity; and there is an abundance of rain for harvesting.

The SABIS® Network has developed schools in different regions in the Middle East and South America, and the concept design had to be contextualised, acclimatised and aligned with local expectations. For example, following the attack on the Garissa University College in April 2015, a top priority was security which necessitated a boundary wall and physical barriers between the buildings.

“Safety on site is also paramount,” comments Anthony Opil, project architect at Boogertman + Partners. “The site is on a steep slope so the buildings were staggered and connected with soft, landscaped ramps – working with the terrain to make the buildings easily accessible to one to another and for the mobility impaired. Courtyards were also designed for different age groups with specific play areas for the lower school and high school – which was an approach that was customized to local expectations.”

The school is bound by two roads to the north and south respectively, with the northern road being a busy highway. SABIS® had to provide a budget and infrastructure to access the southern road, which is much lower and further away from the school. The original design was mirrored in order to avoid traffic and highway noise; and cyclist facilities and school bus facilities were provided.

A Tailored Response

Another key consideration was resource efficiency. While there is a greater reliance on mechanical ventilation and heating in other countries, in Kenya, with its high energy costs and a consistent climate, a more appropriate response was developed.

The classroom blocks were oriented north/south with openings, particularly in the study areas, that do not face east or west. Heat gain from outside surfaces was limited by merging soft and hard landscaping and, in the site planning, by ensuring that paved spaces do not bounce heat back into the internal spaces. Air pollution was also mitigated by ensuring that the school bus parking areas, which are planted with young trees, are oriented to prevent exhaust fumes from entering the buildings.

Locally available materials and technologies were specified where possible, such as concrete hollow blocks and roof insulation to improve thermal massing. This was a departure from the typical local construction practice of using natural stone because, says Opil, the hollow blocks were more climatically appropriate, enabled costs to be reduced, and were readily available thus circumventing supply issues relating to stone.

Natural lighting and ventilation were modelled and optimised by increasing the height of the windows specified in the original design. Together with the selection and procurement of low-VOC finishes – such as paints, adhesives and sealants – to ensure that the children are not exposed to toxins, this ensured a significant improvement in the school’s Indoor Environmental Quality. Elizabeth Chege explains that, although the AP team did not conduct embodied energy calculations for materials, this strategy was used to govern the specification of materials; and workshops were held with both the client and contractor to ensure that targets were met.

Solar water heaters were installed to reduce energy consumption, and a modular solar PV system was designed for optional adoption – with the aim of providing panels for classrooms in the next phase of the development, to cut back on consumption and reduce operational costs.

Electricity and water sub-metering was provided for each block with smart meters connected to the BMS to monitor and manage consumption, and to offer a learning resource for the school children and their carers. The school was also the first in Kenya to install 100% LED lights in all spaces, thus gaining an additional Green Star Innovation point.

Targeting Net Zero Water

Boniface Chege, also of WEB Limited, says that the project is performing so well in terms of water consumption that the team will consider targeting a Net Zero Water certification which, if successful, will be the first in the region. “We had to consider how children behave and how they like to play with water,” he says. “We reduced consumption by specifying low-flush toilets and low-flow taps with sensors.

“Potable water consumption for landscape irrigation has been reduced by 100% using a rainwater harvesting system and recycled black water system. This is backed up by a borehole with variable speed drive (VSD) pumps and municipal water as a last resort. For the Green Star rating, we achieved 99,9% of the available water credits just by using context-appropriate systems like efficient fittings and a blackwater treatment plant – thus contributing to the long-term resilience of the school.”

Elizabeth Chege adds, “To treat the sewage emanating from the facility, a membrane bio reactor (MBR) – a process of membrane-based technology – was provided. In this process, the excess sludge does not require separate digestion and the quantity of sludge generated is minimal. This avoids the cumbersome sludge disposal exercise which needs more manual labour and land area. The treated water from the system is disposed of into an overhead tank to flush toilets by gravity. The supplier and installer of the system was also appointed to maintain the system during operations.

“A workshop is being planned with the school’s operational team to ensure a smooth transition from design to operations by sharing information; and consumption data is already being reviewed. The team will also implement an occupancy survey plan to ensure ongoing comfort and usability for users.”

A precedent in Waste Management

Construction waste is currently a topical discussion in Kenya and this project has become a case study for the National Construction Authority, for other contractors to adopt. The reason, says Elizabeth Chege, is that the tender and preliminary documentation was very clear, so the contractor was informed at the outset of the required standards. The contractor therefore appointed a local waste consultant to ensure that the waste was recycled and reused, and 96% of the construction waste was tracked, weighed and diverted from landfill.

In terms of operational waste, spaces were provided on site for separation of waste; and recycling bins were clearly labelled for use by the school children and staff. Paper and cardboard, plastic, metal and cans, glass bottles, and food waste are all separated during operations. The appointed waste collection company was awarded a contract on the basis that they collect the separated waste in trucks that maintain separation, and they have an extensive sorting site that employs women and youth.

A benchmark for East Africa

“The growth and development of school infrastructure has a large impact on our natural environment and communities,” shared Austin Opiyo, SABIS® International School – Runda Facilities Manager. “The design, construction, and operation of the buildings in which we work are responsible for the consumption of many of our natural resources. We are glad that SABIS® Runda is a leading example of a green school and has gone ahead to be a corporate leader in sustainability initiatives.”

“Research has shown that certain green building factors positively influence learners’ performance at school,” notes Chilufya Lombe, director at Solid Green. “SABIS® Runda is the first school in the SABIS® Network to be completed and undergo certification in Africa, with more planned in future. With this project we have shown that schools, where our children spend most of their time away from home, can be green too. We hope that other learning institutions in Africa will also adopt green building certification and become part of the call to climate action.”

“This certification sets an example for the rest of the region,” says Elizabeth Chege. “We were thrilled to be part of the process of opening up the Green Star Africa PEB tool for countries outside South Africa. The client was dedicated to achieving this aim and the professional team and main contractor were completely open minded about the process, enabling us to efficiently meet the required credits.”

In both its realisation and certification process, SABIS® International School – Runda has successfully set a new benchmark for schools and the green building sector in East Africa.
