Heating, Ventilation & Energy Efficiency Klober Permo ® air gets public sector performance recognition Klober has received a significant boost for its marketleading low resistance airopen underlay Permo ® air with certification by Local Authority Building Control (LABC) for its Registered Details scheme. Designed to meet this requirement and prevent condensation forming in the roofspace, Klober Permo ® air offers an exceptional level of breathability. It has a water vapour transmission sd-Value of 0.009m and a water vapour resistance confirmed to be as low as 0.045 MNs/g. As a result, it has been specified for roofing upgrades of many high profile and historic buildings. BBA and IAB approved, Permo ® air not only avoids the additional cost of supporting ventilation, but also interruptions in the roofline caused by traditional tile or slate vents. Being manufactured from polypropylene, it is also fully recyclable. Commenting on the certification Graham Copson, Product Systems Manager – Components, said: “Certification from LABC for its Registered Details scheme is great news for Klober. Registering Permo ® air with LABC increases industry confidence in this already popular product and it helps ensure acceptance by all local authorities across the country.” www.klober.co.uk/shop/category/air-open-underlay Rinnai: the 1200i continuous flow hot water heating unit - for every commercial site Now available from Rinnai UK, manufacturers of the world’s leading continuous flow gasfired hot water heater units and systems, is the HDC 1200i continuous model for use on all high demand commercial sites. It is capable of delivering in excess of 1560 litres per hour. It guarantees unparalleled levels of efficiency and hot water delivery for the end user whilst streamlining installations and guaranteeing future regulatory compliance. With a continuous flow water heating unit, it will deliver limitless amounts of useable hot water, whatever the site - school, hospital, hotel, office blocks, leisure club etc with no fluctuations in water delivery temperature. The only time the site uses energy to heat water is when there is a demand, in other words, it is only burning gas when a tap or shower is being run. www.rinnaiuk.com Air Vent Technology’s extensive range of heat recovery units Models from Air Vent Technology’s extensive range of heat recovery units are particularly suited for installation into schools, ensuring that buildings are properly ventilated, whilst keeping heat loss during the winter months to a minimum. The new range of Infinity ® low profile heat recovery units are available in 10 standard sizes with airflow up to 4.33 m3 /sec. Options are side, or bottom access, a stacked arrangement if desired, and for internal or external installation. Units are available with either an EHB or LPHW heater battery, and are only some of AVT’s extensive range of ventilation products (air handling – heat recovery - energy efficient with EC motors – cabinet and twin fans and emergency smoke extract units). www.airventtechnology.co.uk New business development manager for Dunham-Bush Dunham-Bush, one of the UK’s leading heating and cooling equipment manufacturers, has appointed Dave Parsons to Business Development Manager of its Cooling Division. Dave has worked for Dunham- Bush for 14 years, joining as a Service Engineer and progressing to the Service Manager role. Having recently gained a BA (Hons) in Leadership and Business Management, he hopes to take his skills base and knowledge gained into his new role. As the title suggests, he will be focusing on expanding the company’s activities in the chiller sector. Dunham-Bush has recently successfully re-introduced chiller production into the UK with a comprehensive range of technically advanced air and water cooled chillers in a range of outputs from 35 to 14,068kW. In addition to chillers, Dunham-Bush manufactures and distributes an extensive range of heat emitters, including LST radiators, radiant panels, fan convectors, door curtains, trench and perimeter heating and fan coil units. www.dunham-bush.co.uk 10 Winter 2019 <strong>4156</strong>
Heating, Ventilation & Energy Efficiency Design Vs Reality By Roy Jones, Technical Director, Gilberts Blackpool. With any building project, new build or construction, we all have a preconceived idea about how it will look, what it will deliver and its expected performance. The reality is often far different… A whole raft of factors will influence the design such as cost, practicality, architectural design, functionality, guidance documents and Standards to name but a few. There is also the one factor no-one can fully evaluate in advance: human nature. With the current drive towards sustainability, a building should be airtight to improve energy performance. The problem with that is that we have to let fresh air in, to avoid such things as damp and that most important consideration - to allow the occupants to breathe. So we develop a carefully calculated ventilation scheme. The building opens and a room feels a little bit warm, so instead of consulting the controls and seeing if the heating system is operating correctly, the occupant simply opens a window without understanding the actual ventilation design. This then can lead to the carefully planned strategy going literally out of the window. Therefore, design versus reality needs to be applied at the very beginning and closely monitored, including post occupation. If cost was no object, almost anything is achievable. In the real world, that is not the case. A fundamental consideration is the compatibility of the individual components into the whole. The products may all achieve particular performance criteria individually, but what about when they are integrated with other elements? Will that impact on the performance and will these be able to be used correctly and understood by the occupant? It is part of the ethos behind the development of the soft landing strategy: aligning the interests of those who design and construct with the interests of those who use and manage it. ...A whole raft of factors will influence the design such as cost, practicality, architectural design, functionality, guidance documents and Standards to name but a few... Soft landings help ensure the reality is as close to design as possible. The design and the delivery team re-visit the project to check that the intent of the design is in place. This also ensures the occupants of the buildings are using the building correctly and are aware of the design and actual expectation from it. BSRIA has launched a new version in recent months - Soft Landings Framework BG54/2018 Soft Landings Framework 2018- 6 phases for better buildings. This latest edition encourages increased collaboration to allow a better delivery of buildings. There are many factors to review but the principle remains the same. Is the building which has been handed over, performing as per the design, and is it working for the occupants? Is it useable and fit for purpose? These checks after initial occupation are vital, to ensure that the building users are aware of how to best operate the systems and controls, to best benefit themselves and meet the designed concept for performance (including energy use) and levels of comfort required for the activities within the building. There is usually some change of use from the original design intent, where adjustments will need to be made to provide the correct levels of performance. Design and reality will always be difficult to match 100%. However, the soft landings approach - of engagement with the occupants, prior to and post occupation - will give a major benefit to ensure the building designed by the engineer, is utilised and used in the correct manner and as close to the design that was detailed. This will therefore enhance the occupiers experience and understanding and provide the best platform to complete the project with what we should all strive for “happy customers”. www.gilbertsblackpool.com Winter 2019 <strong>4156</strong> 11
