"ventilation"

UNIZO office building CHALLENGE Dedalus Architects specified zinc for waterproofing the timber frame UNIZO office building in Eeklo. Not only for the roof, but also for the facade and bottom side of a unique construction detail. To be precise, waterproofing horizontally, vertically and even upside down! To entirely cover the structure however, appeared not to be possible when using zinc. If you opt to use this traditional waterproofing material a ventilated air space must be provided underneath the zinc covering. This of course entails an opening for ventilation purposes underneath the roof edge, if not, condensation will occur. In the case of a building where the facade has to connect seamlessly with the roof and the underside, leaving an opening is not a possibility. So, despite the attractive appearance of zinc, a waterproofing solution with this material was not an option. SOLUTION Thanks to their collaboration with roofer ALBITUM and previous experiences with RENOLIT roofing products, Dedalus Architects came up with a nice alternative: RENOLIT ALKORDESIGN standing seam imitation. A perfect solution for a difficult challenge. No ventilation needed, no connection problems, the same looks as a zinc roof and, above all, more cost effective!

Salthaven Apartments, Tower Road, Poole, DorsetThe Salthaven apartments in Dorset aimed to deliver luxury living for occupants. Bayview Developments not only constructed beautiful homes for them, but also opted for highly energy efficient heating within the new development.Each of the 12 two or three bed apartments have been fitted with their own individual exhaust air heat pump (EAHP). This technology has been installed in buildings across continental Europe for many years but is now being used more commonly within the UK. Bayview Developments were looking to exceed their planning requirements by reducing carbon emissions and providing cost savings for occupants. NIBE’s innovative EAHPs were therefore the ideal solution.The solution to the projectA NIBE F730 EAHP system removed the need for gas boilers, something Bayview were keen to do given the UK’s net zero targets and commitment to phase out the technology. As heat pump technology is powered by electricity, no gas has been installed at the site.The NIBE F730 unit can be found in the utility room cupboard of each apartment and is comprised of a ventilation system, a hot water cylinder and a heat pump – a complete ‘all-in-one’ product. It works by drawing warm air from the kitchen and bathroom to feed the heat pump, which extracts the heat energy. The recovered energy from the ventilation system is used to drive the heat pump process, which heats the underfloor heating and provides water for the integrated 180litre hot water cylinder. The stale air from the ventilation system is then released outside, whilst fresh air from outdoors is introduced via wall inlets with cleanable filters. The efficient system minimises energy consumption by combing ventilation heat recovery with heat pump technology, that is perfect for well insulated new build properties such as these.The ResultsThe EAHP systems meet the average annual heat demand of 6019 kWh for each individual flat whilst also providing instant hot water. Occupants are able to schedule their heating to suit their timetable and energy tariffs, and therefore benefit from lower energy bills. The system performance factor (SPF) measures 3.33 – this means the system is very efficient as every kW of electricity used to run the unit produces approximately 3 kW of heat energy.NIBE utilised connected electricity meters in 3 apartments to remotely monitor the systems performance across a 12-month period. NIBE was thus able to see how the systems met energy demand consistently for residents, keeping them comfortable and warm throughout the year.Energy consumption data shown in Figure 1 visualises electricity consumption data from the monitored apartments throughout the year. This data also covers the provision of all heat pump controls and continuous mechanical ventilation.Figure 1: 2022 Energy Consumption data for monitored apartments.The all-in-one system has shown a noticeable reduction in energy bills for each apartment too, with all 3 monitored apartments experiencing both monthly and cumulative cost reductions in their energy bills as shown in Figures 2 and 3. This comes with the additional peace of mind that consumers will be kept cool in the summer months with ventilation with no increase in costs.Figure 2 and 3: Monthly and Cumulative Heating Bills for Apartment 11 with the NIBE F730 heat pump compared to a natural gas boiler.The occupants of Apartment 11 are saving on average £130 on their annual heating bills with the heat pump system in comparison to a natural gas boiler, even with the additional provision of mechanical ventilation. We expect that these savings will continue to increase as the Government seeks to rebalance green levies to decrease electricity prices.Sunstone Energy Ltd, the installer for this project, told us how easy the control system is to use for this heat pump, allowing for heating and hot water to be available at any time during the day. The building also benefits from insulation, underfloor heating, smart controls, double glazing, hot water cylinders and mechanical ventilation with heat recovery (MVHR).TestimonialVictoria and John are both residents of the Tower Road apartment complex and have been comfortably living with the exhaust air source heat pump system for a year. They added “We are delighted so far with the new heating system, and love that it has been providing us with heating and hot water throughout the year, keeping us warm in the cold winter months. The heat pump works just as well as our older systems and it is great to know that we’re also doing our bit for the environment in the process.”About the installerSunstone Energy Ltd takes responsibility for delivering complete renewable solutions appropriate to their client’s properties.

A new ferry terminal on Brodick Bay, created as a tourism and community gateway to the Scottish Isle of Arran, has been fitted from stem to stern with door and window systems supplied by GEZE.Maritime design and modern comfortThe ship-shaped terminal, designed by the renowned architectural firm Norr of Glasgow, is part of a £30 million investment which aims to update the harbour, get it ready for 21st century travel, and improve passenger comfort.Natural ventilation thanks to automated windowsThe generously sized lounge with its double height and large wall of windows on the western façade offers visitors a breathtaking view of Brodick Bay. The large windows, which are automatically opened and closed by 30 GEZE Slimchain chain drives, give the reception area at the main entrance to the building a bright and spacious feel. The uniquely slim and understated look of the Slimchain window drives integrates perfectly into the unique façade design of the Brodick ferry terminal.The Slimchain window drives were installed not only on the large windows in the lounge, but rather throughout the entire two-storey building – with the exception of the upper ventilation openings: Powerchain chain drives are used there. These especially powerful window drives were chosen to operate the larger windows, since they allow for large opening widths – which is important for quickly venting smoke in case of a fire.The window drives are connected to a GEZE MBZ 300 SHEV control panel for smoke and heat extraction drives, which is integrated into the building management system of the terminal. This makes it possible to easily control and monitor the complex natural ventilation system.Ventilation, smoke and heat extraction, and emergency exit protectionThe windows in the staircases are also equipped with Slimchain chain drives. If needed, the window systems also allow for natural smoke and heat extraction: In case of smoke and heat, the smoke extraction solutions open the windows and control fresh air openings, so that lifesaving escape routes remain smoke-free and safe to use in case of an emergency. In addition, GEZE OL Line manual fanlight openers provide supplementary natural ventilation.Door systems for accessible fire protection doorsBeneath the glazed western elevation are two automatic swing doors to either side. These are powered by GEZE Slimdrive EMD-F door systems, just like another door on the side façade of the building. The electro-mechanical swing door drives for single leaf fire and smoke protection doors are extremely versatile: They provide power assisted opening and can be initiated using the operating button with constant opening and closing speed. Integrated obstacle detection also identifies potential obstacles and stops the opening or closing process if needed. By doing so, Slimdrive EMD-F drives also ensure easy and safe access for people with mobility issues.Understated design and high access convenienceFrom the main entrance, a glazed corridor leads to a bi-parting sliding door powered by a GEZE Slimdrive SL NTsliding door system, which leads into the foyer of the main reception area. The Slimdrive door drive fulfils two key stipulations here at once: It is suitable for interior and exterior doors with high levels of footfall, and ideally suited for glass façades with high design standards – such as the Brodick ferry terminal – due to its low operator height of just 7 cm.

Harbour Central is one of the most recent developments in Canary Wharf, one of London’s two financial centres. There will be 5 residential buildings and a leisure complex. The main building of the development will be the Maine Tower with 42 floors. The upper floors are quite promising, as they will comprise breath-taking panoramic views of London. The Effisus Breather breathable membrane was the chosen solution for this project, in order to ensure the watertightness of the façade, and, at the same time, to allow ventilation of the façades components.

A landmark London entertainment venue is under refurbishment and will feature striking black windows that will not only suit the style and appearance of the Grade II listed building but also meet modern performance criteria for thermal insulation, fire safety, security, and ventilation.
