The science behind roofing

A roof is a building’s last line of defence against the elements. But how efficiently it performs is a science in itself. Klober gives us an insight into the depth of their product development

Look up at a roof and what you see depends upon your perspective. If you’re in the construction business, your eye will naturally be drawn to the more technical aspects – why has a tile been chosen, how and where is the roof ventilated, what type of flashings have been used?? Professional interest goes beyond curiosity, as it’s the choices a roofer makes day in day out that secure his reputation.

One man who knows only too well the importance of roofing performance is Dirk Willen, who has been part of the Klober Product Development team in Germany for more than 20 years. Dirk takes up the story of the innovation, precision, testing and development behind each and every one of Klober’s products.

“Product development today can be so much more accurate and efficient than when I started back in the 1990’s. Then of course it was all still very much about using the drawing board and very basic digital facilities so it took some time to bring a project to fruition. Now, with CAD and 3D printing we can prototype much faster and make the development cycle a lot shorter.”

Whatever the drivers behind product’s design, Klober has a highly experienced team that considers all of the many requirements it will need to fulfil. Weathertightness is the primary consideration of course and Klober has at its disposal the dedicated Technical Testing Centre of parent company Braas Monier. This has weather stations across the world, and from the data they collect it can feed in the most accurate climate intelligence to the profile of any new product. Wind speed, rainfall, UV exposure and temperature are critical factors as a roof in the southernmost part of France has very different demands placed on it to one in most of the UK. In Alpine regions you will find low pitch roofs with huge spans which need to be protected from the weight of heavy snow.

Dirk added, “Durability and accelerated weathering tests are carried out to ensure products will withstand the severest conditions and as one of the few manufacturers in Europe to have our own wind tunnel we can subject them to exhaustive testing in line with the latest legislation and norms. We then examine whether we have existing tools available for production or will need to manufacture new ones. Of course, products such as vents and dry fixing accessories are a very visible part of any building means so we also need to take appearance as well as performance into account. A contractor wants to use products that are easy to use and offer the best long-term performance, but these days a tile or slate vent must be unobtrusive too. This makes colour as important as the vent profile so we ensure that pigments used offer the greatest durability. A colour will often look quite different once installed and also depends on the material used to manufacture it. Colour matching is a real challenge as the shade will vary between grooves, recesses and raised areas – it’s all very subjective. To obtain the best consistency we use a light chamber with precisely defined wave lengths and then cross-reference against the human eye. It’s always a battle against the elements which, over time, will always take their toll.”

Before manufacturing of a new product begins, it is also subjected to an extensive programme of trials and testing. These are carried out to ensure compliance with international and local standards as well as with Klober’s own, more demanding specification. Each individual test programme is based on a ‘failure mode’ analysis and it is only when all the processes are complete that the product is considered fit for launch. At this stage, the expert knowledge and insight of contractors is invariably drawn on prior to the commitment to full production. Dirk added “We regard our customers as partners and it is up to us to ensure we make their lives as easy as possible. We very much depend on interaction with them to further our deep well of knowledge and expertise in roofing built up over more than 50 years.”

Klober is well-known and respected for the way that existing products and their performance are considered integral to any research. This ensures that established product ranges continue to be fully supported, kept up-to-date and benefit from improvements ahead of the market. Dirk concluded, “In terms of answering technical enquiries this invariably means Klober is able not only to offer a solution which others may struggle to provide but have the confidence to address problems arising from complex roofing designs”.

How to provide on-demand commercial ventilation without the upfront cost

When designing a new ventilation system for your commercial premises, one of the many aspects that need to be considered is the ongoing running costs of the system. Whilst a BMS (Building Management System~) offer the building manager the ability to control the building’s ventilation and remotely monitor the system’s performance, they can add significant cost to the ventilation system’s initial outlay. There is, however, an alternative that still grants the building manager and the occupants of the building demand-based ventilation without the large upfront cost of a BMS – a VAV System.

A Variable Air Volume (VAV) system can be used in conjunction with market leading commercial MVHR systems such as Airflow’s Duplexvent range. They enable the occupants and the building manager the ability to adjust the level of ventilation to different rooms or zones of the building based on localised changes in demand.

With air pollution making the news for the wrong reasons coupled with a drive towards increased energy efficiency it is key that you have a ventilation system that gives the occupants a healthy and comfortable indoor air environment whilst remaining energy efficient and cost effective.

Intuitive VAV Dampers work by communicating directly with the MVHR system to adjust the system’s ventilation swiftly based on changes in ventilation demand. When combined with humidity or CO2 sensors, a VAV system can automatically respond to changes in room or zonal occupancy, independent to the other areas of the building.

This differs from many centralised MVHR systems that don’t use demand-based control. With these systems, the ventilation rate remains the same in each room regardless of occupancy level. This leads to one of two things:

Either the room is being unnecessarily over-ventilated, which is wasting energy and increases ongoing energy bills of the premises, or
Busy areas are not receiving enough ventilation and as a result, those in the room are breathing unhealthy air that can affect concentration and productivity levels and in worse cases can worsen respiratory issues. Furthermore, there is the chance that damp and mould can develop within the room, which as well as affecting the health of those inside the area, can damage the fabric of the building itself.

Whilst this functionality can be found within a quality BMS they can add significant cost to the development. By using a VAV system, you gain the level of control and responsive ventilation you’d normally receive through a BMS without the initial outlay that goes with it. With spending being increasingly held to account, why would you pay more when you can get a system that offers the same level of performance for less?

UK air pollution and its impact on Indoor Air Quality (IAQ) in schools

The UK – alongside Germany, France, Italy and Spain – have been issued a final warning by the European Commission for failing to address breaches of air pollution limits for nitrogen oxide. EU Member States have been repeatedly asked to implement air quality plans to safeguard public health, but the requests have fallen on deaf ears.

For many, it may seem as if air pollution isn’t a threat to the UK. After all, smoke-spewing furnaces and coal mines have wound down considerably in recent years. However, just because we can’t physically see air pollution, it doesn’t mean that it isn’t present.

In a survey of 1,670 adults, 58% believed that the current levels of air pollution in the UK are either harmful or very harmful to overall health. The issue of air pollution has been felt particularly acutely in the capital. Just one month ago, it was recorded that the air in London was far worse that in the notoriously polluted Beijing for the first time.

The issue of poor air quality mustn’t be ignored

Areas which display high levels of air pollution are located close to several London schools, which is particularly problematic as the young are more susceptible to health complications concerning air pollution. Summed up nicely by London Mayor, Sadiq Khan:

“Every child deserves the right to breathe clean air…it is a shameful fact that more than 360 of London’s primary schools are in areas breaching legal pollution limits.”

To better safeguard pupils, schools have been advised to ban playing outdoors in some of the more serious cases, as well as introducing ‘no idling’ zones to prevent drivers leaving their engines running while waiting for children on the school run.

This polluted air, present in the UK’s major towns and cities, infiltrates buildings that house vulnerable occupants such as children in schools unless sufficient care is taken to install ventilation and air quality management systems that are able to control the volume and quality of air brought into the building. Management of Indoor Air Quality (IAQ) is an important issue, not just for health but for performance and behaviour too.

Causes of poor IAQ

Poor IAQ is caused when there is a build-up of pollutants inside a building due to little or no ventilation, or as a result of pollutants being directly brought in through open windows or unfiltered ventilation systems. Pollutants can arise in the school environment from various sources such as furnishings, IT equipment, bio-effluents, or from external pollutants such as nitrogen dioxide and carbon monoxide. In addition, CO₂ levels can become dangerously high just through the concentration of children in a poorly ventilated classroom.

Impacts of poor IAQ

Being inside of a school building doesn’t mean that the pupils are protected from poor air quality. It is crucial that the conditions inside are conducive to a healthy and productive environment. If poor air quality is evident in schools, it can have a wide-ranging impact.

Due to high levels of pollutants, the UK has the highest prevalence of asthma in the world[1].
Poor IAQ can lead to an increase in cardiovascular illnesses[2].
Lung irritation can occur, symptoms which can be exaggerated in school children as their lungs are not yet fully developed[3].
Proven correlation between inadequate ventilation in schools and poor pupil performance. A study by the University of Reading demonstrated that the attention span of school children is significantly slower when the level of CO₂ in classrooms is high[4], which could have an adverse effect on pupil attainment

Considerations when looking at the different solutions

Naturally, the solution would be to invest in a ventilation solution which can combat the problem and provide the optimum indoor air quality (IAQ) for school pupils. However, opening a window, a form of manual natural ventilation, is not recommended. Firstly, this method does not take account of demand and therefore cannot effectively control CO₂ levels, and secondly opening a window will let in polluted unfiltered outdoor air. This can make the school environment harmful to pupils and staff.

Mechanical Demand-Controlled Ventilation (DCV) systems provide the best solution to these problems in schools. Intelligent controls detect and predict rises in CO₂ levels in a room, reacting instantly to draw fresh filtered air in whilst the stale air is extracted in a balanced way to avoid unnecessary draughts. This also avoids wasteful over-ventilation, especially in winter, thus reducing heating bills for the school.

It is critical that the quality of air surrounding school buildings is considered, and its impact on IAQ in city schools is really important. Implementing effective ventilation solutions is vital if the health of our children is to be safeguarded. Breathing in clean air shouldn’t be something which is desirable for school pupils, but as Sadiq Khan correctly said, it should be every child’s right.

Low income families are typically more affected by air pollution with children most at risk. The UK currently has over 40,000 deaths a year linked to poor air quality costs the economy billions a year. With indoor air pollution often 50% worse than outdoors and can contain up to 900 different pollutants it is imperative that a suitable system is installed to improve the health of the occupants as well as protecting the fabric of the home itself.

Mechanical Ventilation with Heat Recovery (MVHR) is the process of continually preheating filtered, incoming fresh air from outside by warming it with the outgoing waste air which is created by kitchens, bathrooms, utility rooms etc. Once the warmth is transferred, the now warm, clean air is the supplied to the living areas such as living rooms and bedrooms.

The following example will show the cost benefit of having a MVHR system installed in the property. This example assumes that both properties are 300m² in size.

House A	House B
Uses extract and trickle vents to ventilate the property. It has 2 air changes an hour and uses gas heating to warm the property	Uses an MVHR unit with 71%* heat recovery. It has an air change rate of 320m³/hr (89 l/sec), assuming no infiltration and uses gas heating to warm the property
Heat loss from infiltration at 2 ach 14,164 kWh per year at a cost of £0.0359 per kWh = £508.49 per year	Heat loss due to ventilation at 320m³/hr at 7677kWh with 71% thermal efficiency = 2226 kWh. With a cost of £0.0359 per kWh = £79.92 per year
Cost of running a bathroom and kitchen fan operating at 1 hour per day at 0.05kW = £2.08 per year	MVHR with two fans running, operating 24 hours a day at 693 kWh = £104.70 per year
Total ventilation energy cost = £510.57 per year	Total ventilation energy cost = £184.62 per year

Additional saving with 80% thermal efficiency = £16.54

Additional saving with 90% thermal efficiency = £34.90

All new Airflow domestic MVHR units have a thermal efficiency of 90% or greater so you stand to see up to a £355 per year reduction in your energy bills.**

^{*Domestic Building Services Compliance Guide Section 8 specifies a minimum thermal efficiency of 70%}

^{**assuming a kWh price of £0.0359}

An ideal MVHR system to be used in social housing settings is the Adroit

Airflow Adroit MVHR units can be set up during the commissioning process to limit the tenants’ access to the control system. This removes the issue of tenants changing the ventilation rates for the property as well as them switching the unit off, guaranteeing effective ventilation always takes place within the property; protecting the health of both property and tenants. Your tenants, however, will still be able to tailor their ventilation around their daily routine through selecting the relevant ventilation profile to suit their needs.

As landlords, you would be able to remotely monitor the performance of the unit and be notified of when maintenance, such as changing the air filters, is required and in turn prolong the lifecycle of your Adroit unit.

Furthermore, in our Adroit DV50 and DV80 models, you can have these installed above the entrance to the property, so maintenance can be undertaken to the unit without disturbing the tenant.

Airflow is proud to announce that we have introduced a new outdoor line to supplement our hugely successful Duplexvent Rotary MVHR range: the Duplexvent Rotary-N.

The Duplexvent Rotary-N are all-purpose rooftop units that can improve the indoor air quality of various different commercial premises such as schools, restaurants, office blocks and warehouse whilst protecting the health of those working within the building as well as the fabric of the building itself. The compact design of the Rotary-N allows for a discrete installation and helps you to maintain an aesthetically pleasing design of the premises.

The Duplexvent Rotary-N helps to reduce the property’s energy costs thanks to its highly efficient rotary heat exchanger that can recover otherwise wasted heat energy and use it to pre-warm the incoming filtered, supply air. This means that the building’s heating isn’t warming the workplace as much as normal and in turn can reduce the energy bills of the property. This brand new range comes in 7 different models and is able to extract from 1550m³/hr (431 l/sec) to 16700m³/hr (4639 l/sec) with impressive sound levels from just 34dB(A).

Following on from the launch of our new Duplexvent Rotary-N range of commercial MVHR units, Airflow have also expanded our range of the existing Duplexvent Rotary range of compact, indoor commercial MVHR units with rotary heat exchangers.

With 7 units from you to choose from, there’ll be something to meet your ventilation needs. They are ideal for schools, offices and halls and will improve the quality of air circulating through property. The Rotary range can supply up to 16700m³/hr (4639 l/sec) from an unnoticeable 34dB(A).

All Duplexvent Rotary and Rotary-N units can filter out small airborne pollutants such as pollen or dust thanks to the unit’s ability to be fitted with G4, M5 or F7 air filters. This helps to maintain a healthy indoor air environment for those within the building. By maintaining a healthy indoor air environment, you protect from indoor air pollution, which research shows can affect productivity, concentration levels and in worst cases even cause severe health problems.

All units have 85% thermal efficiency thanks to the highly efficient rotary heat exchanger. Duplexvent Rotary units can be fitted with G4, M5 or F7 filters. The units adhere to the current ErP Ecodesign Directive requirements including the stricter, draft 2018 regulations. Furthermore, they help you achieve Passive House approval, thanks to their extremely low SFP values of less than 0.45W per m³/hr. Each model has T2 level insulation, an integrated web server and a sophisticated yet user friendly control system.

Ventilation in Schools – Preparing for the New Building Bulletin 101

Building Products Index Ltd October 24, 2016 Ventilation Leave a Comment

View the Jaga entry on BPi

View the Jaga website

The consultation process for the new BB101 closed on the 25^th August 2016, Andy Williams from Jaga looks at what the proposals mean for the HVAC industry.

The means by which we ventilate our schools is one of the defining factors in creating and maintaining standards of health and comfort that allow students to thrive. But how we set about designing and regulating ventilation systems to best achieve optimum levels has been a slow evolving process. Now, however, a change for the better seems to creeping over the horizon.

The Department for Education (DfE) is currently in the process of updating the Building Bulleting 101 (BB101), which is being produced to fall in line with Education Funding Agency (EFA) Guideline Standards – in particular its ‘Facilities Output Specification’ (FOS). The proposed new name will be ‘BB101 – Guidelines for ventilation, thermal comfort and indoor air quality in schools’.

Whilst entirely subject to change, architects, building services engineers and education decision makers need to be aware of the direction the DfE wants to go with regards to ventilation in schools.

IAQ & Thermal Comfort – BB101’s Two Big Changes

Based on the draft BB101 proposal, there are two main factors that seem to be of the greatest importance when discussing Indoor Air Quality:

– CO₂ levels

– Thermal comfort.

Schools in the UK have traditionally been ventilated by means of either fix speed mechanical or natural ventilation. Natural ventilation often consists of a somewhat unsophisticated strategy – essentially, opening and closing a window, which is far from effective in measuring and maintaining sufficient Indoor Air Quality (IAQ). Similarly, fixed speed mechanical systems ventilate at a pre-determined rate, which has little regard for the actual requirements at any particular time.

Studies have suggested that the perfect conditions for an average classroom would be 1200 parts per million (ppm) of CO₂ in a room – a level not consistently achievable through natural ventilation, which has a maximum recommended limit of 2000ppm. As such, with a need for more accurate control of CO₂ levels, we are expecting a greater drive for more sophisticated methods: demand-controlled mechanical or hybrid ventilation.

Because demand-controlled mechanical ventilation is intelligent, it can react to the conditions within a room automatically, with CO₂ sensors constantly monitoring indoor air quality. That means that if it is programmed to control CO₂ levels to never exceed 1200ppm, by means of automatically introducing a fresh flow of air into the room when required and extracting the stale air, the perfect balance can be achieved without any manual input from staff.

In terms of thermal comfort, BB101 will seek to advise specifiers on how to prevent overheating, whilst becoming considerably more efficient via effective heat recovery – but will do so in a way that provides greater clarity in the quality of systems that should be used. Variabilities must be accounted for under greater scrutiny, be it the fluctuating radiant and air temperatures both inside and outside of the classroom, which can only be effectively managed by using an intelligent ventilation system.

Seeking Greater Control

(either full mechanical or hybrid) should be seen by all school construction stakeholders as the primary choice to adhere with new BB101 guidance. But it is not just a case of meeting compliance; it should be about exceeding the recommended standards to ensure that children have an optimal environment in which to make the most of their education.

Airflow Developments has released the next generation of its MVHR ventilation units – the Adroit MVHR range. Ideal for high-end housebuilders and property developers, these Passive House certified units are equipped with the latest smart technology that allows air flow settings to be controlled within the home or remotely by PC, Tablet or Smart phone.

Leading ventilation manufacturer Airflow Developments has launched its Internet capable Adroit MVHR range for the domestic market. Utilising mechanical ventilation with heat recovery (MVHR), the systems recover valuable heat that would typically be lost as part of the ventilation process from wet rooms and use this energy to pre-warm clean, fresh air that is constantly brought in from outside and circulated within the home.

Crucially, the units are equipped with the latest interactive smart technology that provides homeowners with real-time monitoring and control of indoor air environments – at home or on the move. Once registered to the Adroit Cloud Service, the air flow settings of the unit can be controlled via a computer or mobile device. Moreover, the unit is also able to connect into house automation through the Modbus, or be controlled via a fixed controller.

Easy to use and with an intuitive colour display, the control panel is a responsive, portable interface, which provides a step-by-step guide on how to successfully manage the ventilation unit. Designed with four different profiles to choose from – Home, Away, Boost or Fireplace function, users are able to programme the units according to their personal routines and preferences. For example, setting ventilation to ‘Away’ during workdays will avoid unnecessary air filtration into the premises and therefore reduce energy costs and wastage.

For those wanting to offer additional benefits to potential homebuyers, there is also the option to install two external switches. For example, one switch can be set to ‘Boost’ profile within a kitchen or bathroom to accommodate for fluctuating indoor atmospheres, and another can be programmed to alternate between ‘Home’ and ‘Away’ profiles. Cooker hood boosting is also possible when a compatible recirculating cooker hood is in place.

“The highly sophisticated Adroit MVHR range is a complete whole-house ventilation solution that not only effectively delivers fresh, healthy air into the home but can also be controlled, monitored and managed by portable devices,” said John Kelly, Marketing Manager at Airflow.

“Over 15.3 million homes in the UK are estimated to be at risk of Toxic Home Syndrome; and with homebuyers becoming more aware of the dangers of poor indoor air quality it is more important than ever for housebuilers and property developers to specify efficient, eco-friendly ventilation solutions. Additionally, with the development of smart homes and increasing pace of innovation, it is also imperative to consider tech savvy solutions. The Adroit MVHR range is a cost-effective Internet capable solution that will also contribute towards optimum build performance.”

The Adroit MVHR units also incorporate low energy/noise EC fans, a triple filter system to reduce airborne pollutants, automatic frost protection, a 100% bypass facility and also has an intelligent temperature and humidity sensor inbuilt. An optional carbon dioxide sensor makes it easier to monitor and maintain internal comfort levels.
