Editor's Notes
- I am the President of the HPHI and a member of the “Passivistas design team” and I’m very glad to be here to share with you our experience for PH in the MED Climate; I will short show you some data about the project and then I will present you the data collected these past 2 years. This project is an energy upgrade and retrofit of a typical 142 m2 single-family + Office house of the ‘60s in Greece according to the Passive House standard.
- The building is located in Athens, which is in the middle of Greece and has a mild climate; so the goal was to eliminate the need for conventional heating & minimize the need for air conditioning. It is located in the Papagou Municipality, on the western slope of mount Ymittos.
- The building was built back in 1964 on a 520 m2 corner plot the two street façades are looking south-east and north-east. So the orientation was not perfect.
- It consists of two units: on the 1st floor there is a 98.80 m2 typical private residence with 2 bedrooms, a bathroom, a separate kitchen and a living room entrance area. Its layout was not altered much, apart from this wall that separated the kitchen from the living room which was demolished to increase the flow of southern light towards the living room and there is a separate 43.60 m2 storage/boiler room on the ground floor; this one was converted into an office, the HPHI’s headquarters.
- The existing building was of massive construction (reinforced concrete slabs, columns and beams –marked in black- and perforated brick walls – marked in grey. It was completely uninsulated, as you can probably guess seeing the heating & cooling demand values and it’s airtightness Windows were wooden and single glazing. There was a conventional heating system with oil boiler and radiators + a big stove. There were also 2 Minisplit Units for cooling the house.
- 15 cm of EPS were applied resulting as external insulation in a U value of…
- The roof was also uninsulated 30 cm of EPS were applied resulting in a U value of… A light weight system was chosen so as not to put a lot of weight on the old concrete slab
- The building had major thermal bridges all around its perimeter due to balconies and protruding structural elements. All existing thermal bridges were resolved and their new ψ-values were calculated accordingly in Flixo. These are photos of the insulated parapet.
- The house had old wooden windows with single glazing. Pvc frame windows were installed on the ground floor and 2 aluminum frame windows were installed this way on the 1st floor’s living room. Triple glazing and Swisspacer were used.
- The airtightness layer on the walls and ceiling is plaster. On the floor we placed an airtight membrane on top of the insulation layer, sealed with tapes to it’s connection with the walls.
- The existing building was heated with oil and radiators and a traditional fireplace, and had two 2.5 kW split units for cooling. All of these were removed. New heat recovery ventilation (HRV) systems were installed, one for each unit (house and office). The residence unit is also coupled with a 30 m long, 2.00 m deep ground heat exchanger. Outdoor air inlet Exhaust air outlet The ground heat exchanger decreases the incoming air temperature down to 25–27 °C during summer.
- For the office, a bigger unit has been installed with 250 m3/h capacity to cover the presence of 10 people, for example, during courses Outdoor and exhaust air inlet/outlet That’s all from me, Stefan is taking over now
- In January 2017 the designed PV-system of 14 panels (3,5 kWp) was installed on the roof of the building. It was expected to cover all the electricity needs of the building.
- According to (updated) PHPP calculations the energy balance of the building after the Renovation was the following. The heating period was less than 5 months. After installing the PV , the building is an ENERPHIT PLUS Building, the first certified globally, according to PHI’s data.
- We have a pretty good measuring system in the building. We can measure all electrical consumptions separately , Temperature, humidity and CO2 , as I showed you, in three points in the building and one point outside. All data are collected in cloud and we can download and compare any kind of them. We also use some simple automatizations to control the HVAC units
- Also the temperatures measured inside and outside the building were very close to the ones used in PHPP. Lowest average daily temperature during winter was 20°C and highest average daily temperature measured in summer was 25,70°C. Again here we can see that February was extremely warmer than normal (+4°C in average). During summer the average external temperatures were close to the phpp data, but the hot peaks were lower.
- The cooling period for the residence started at June 19th and ended at September 9th. The average temperature of the residence (living room) was 25,2°C. The average temperature in the bedroom was 0,5°C higher, but still comfortable. The average temperature in the office (after active cooling started) was 1,5°C lower.
- Using only the minisplits, now for heating the building, it’s interesting to compare the two winters we have leaved in the house. And as you see , although the winter was colder , the inside situation is much better and stable.
- These are the total results of the consumption of the building for 2016 compared to the updated PHPP. As you can see, the results are pretty good. There are some differences in February and July/August , but there are reasons for that. February 2016 was the hottest February since 100 years July/August were hot enough , but as you will see later , our Splits are better than predicted in PHPP. We didn’t cool the office until the middle of August.
- This is 2016 in numbers. What we have updated in the PHPP after measuring one year , were mainly the following : The internal heat gains. We are a family without children, who doesn't cook so much. We don’t use very often the condensation dryer (because we dry in the sun) and finally we always take quick showers. So we have recalculated the gains and reduced them to 2,4 from standard 3.0 W/m2. Of course this increased the heating demand, but also decreased the cooling. The performance of the minisplits needs more calibration in summer , which we intend to do next coming one. The consumption of the led lightning is much better than predicted. But also less heating load. The consumption of some electrical appliances was better. We needed something like 1.5 euro per day to run the house.
- This is the PHPP calculation for the PV system, which makes the building EnerpHit Plus.
- And as Wolfgang Feist said : Passive House+ RES vs. Low Energy House+ RES in Athens. Still has #passivehouse big advantage.
- As I told at the beginning , I am also president of the Board of the Hellenic Passive House Institute since 2013 , when it was established.
- In these 5 years and in the middle of a financial crisis we have done a lot of things about PH. We are an organisation with 150 members, among them the biggest companies from the building sector.
- Two certified projects are existing in Greece and we are expecting to have at least another two by the beginning of next year. Also two certified aluminum window systems are in our market.
- And finally we participate in two european programs SEEDPASS and FIT-TO-NZEB together with several MED partners.
- The question is : do we understand the NZEB? And if yes, do we have the appropriate staff with enough knowledge capacity to design and implement it , especially in the renovation market?
- Many experts are dealing more with what it’s in the blue box and forget the green one. But this is like continuously dropping water in a bucket with holes Three steps : Efficiency of the envelop first Optimization of systems Production of RES on site
- We have engineers and craftsmen , we have the tools but the procedure still doesn’t work well. The chain often brakes , especially between design and implementation
- And sometimes we come to these results
- These issues are more intense in countries like Greece where the construction sector collapsed because of crisis and there is still no definition about NZEB
- Thank You.
