Defective Skylight’s Continue To Cost Polish Retailers Millions

Warsaw 27 February 2014

Skylight 3

Defective skylights currently cost Polish retail industry millions of Euros a year in energy loss. So far the extra over cost is picked up by the retail centre tenants who share in the loss. Since 2013 SOLIDEA Group EVE® team have surveyed over 1 million m2 of Retail Roofing in Poland reporting that more than 80% of skylight smoke vents are found to be defective the majority only needing simple adjustment.

 

In 2013 The Skylights Were The Highlights

Comparing surveyed retail centres in Poland the Czech and Slovak republics in 2013 Poland has without question issues with skylights. Smoke ventilation skylights are installed according to the local fire requirements in the European Union, it usually means that between 3% and 5% of the total roof area is operable to evacuate smoke in the event of a fire. On large retail projects as much as 20% “EV” [Energy Variation] occurs as a result of defective smoke vents. “EV” is a negative it means energy loss. Continue reading

“Hazardous Surveying” Asbestos and Indoor Air Quality

Warsaw 27 August 2013

Asbestos Fibres

Asbestos was a widely used fire retardant material which was woven or encapsulated in building materials and system to prevent the spread and passage of fire. As “Asbestos Abatement” took hold in Western Europe Central European manufacturers took advantage of low cost Asbestos raw materials for more than two decades.

“As asbestos contained materials [ACM’s] near the end of their usable life cycle they become dry and as they decay they crumble easily releasing toxic micro fibers into the air we breathe”        

Woven into concrete Asbestos creates a low cost strong and rigid materials for such systems as roof panels, insulation boards, pipes and conduits although these materials present a real danger to health in some conditions they can be readily seen decaying all across Central Eastern Europe.

Why is Asbestos So Dangerous?

Asbestos occurs naturally in minerals it consists of tiny hair like fibers which once inhaled can remain in the respiratory system for many years where they can causes various forms of malignant lung cancer including Mesothelioma, and Asbestosis. Inhalation risks other illnesses as a result of mechanical damage. In any building environment where Asbestos is installed Asbestos is a significant risk to all building users. Reasonable exposure to Asbestos now can go undetected however be fatal later in life. Smokers who are exposed to Asbestos are at considerable risk from malignant lung cancer. Continue reading

Get A Surveyor! – Mitigating CO₂ Can Cost Lives

Warsaw 19 August 2013

Radon Kills

Who better understands the impact of CO₂ mitigation than the SOLIDEA Groups EVE® team? During the many technical due diligence and conditional surveys to date the EVE® team has recorded thousands of insulation, air tightness, and other building defects. But did you know ongoing insulation of buildings in Central and Eastern Europe designed to mitigate CO₂ emission actually puts lives at risk?

The Hazards of Radon

After cigarette smoking and radon exposure together, cigarette smoking and thereafter radon alone are the number one cause of lung cancer in the European Union. As more people stop smoking [and stop smoking near others] lung cancer cases clearly decrease as a result of smoking habits.  However cases of lung cancer as a result of building sickness and radon exposure are increasing at an alarming rate.

Buildings Don’t Need to Breathe Only People Do!

Campus OneWarsaw 14 February, 2013

Commercial buildings which do not achieve Air Tightness often waste 20% to 40% of the total energy that they consume. When the building envelope is not tight energy is simply lost to the outside. Defective roof lights, smoke hatches and curtain walls, a result of poor design, defective construction, or incomplete maintenance is widespread. “We waste so much energy for no good reason” says SOLIDEA’s Steve Walker  “Air Tightness is the big ticket cost in retail, commercial offices and hotels, and it has nothing to do with the level of Insulation installed”

What is Air-Tightness?

The level of Air Tightness in a building is measured as Air Permeability it is the measurement of the volume of air which leaks through the building envelope per hour per m² of building envelope at 50 Pascals Differential Pressure. Air Permeability is then expressed as a rate for example 3 m³/h. m² at 50 PA which is much better than 7 m³/h. m² at 50 PA. We can test Air Tightness on site and we can easily quantify the energy losses simply by measuring Air Permeability Continue reading
