We want to buy and build a newly constructed, fully planned half of a bungalow without a basement and with a hipped roof.
Please excuse any incorrectly spelled or misnamed technical terms – we are laypersons.
After reading a lot, we are now in the “phase of uncertainty,” which is probably familiar to many here ;-)
Here are some details about the project:
Hipped Roof Bungalow Half
- Building foundation made of glass foam gravel with reinforcement, compacted, concrete, base slab covered to be moisture-tight (this is probably the slab-on-grade)?
- 6cm (2.4 inches) insulation layer, 6cm (2.4 inches) floating screed
- Exterior shell 36.5cm (14.4 inches) aerated concrete in system blocks or Y-Tong plan blocks W-PPW 2-040, MSH steel profile 120/80/5 as support in the bathroom (ceiling) window area – for what purpose?
- Double layer reinforcement with mesh and scratch coat on the exterior
- Windows with Uw = 1.0, triple glazing
- All rooms have windows (open plan kitchen/living area, utility room, bedroom, bathroom)
- Room height about 2.5m (8.2 ft), house height up to the ridge 6.11m (20 ft)
- District heating (underfloor heating in all rooms)
- Attic accessible via hatch, insulation between rafters in the roof
- Usable floor area 114m² (1,227 sq ft) (footprint 88m² (947 sq ft))
That’s the rough information so far. More details gladly available.
Through this forum, I learned about passive and active ventilation (and also KfW 70 due to funding incentives ;-)).
Our question regarding active/passive ventilation: Is it necessary under these circumstances? We both work full-time and often don’t have the chance to ventilate additionally around midday. We would prefer to invest the money saved from not installing or discussing a ventilation system into our list of special features.
A thermal protection certificate with data for our house type and even the house number, according to the Energy Saving Ordinance 2009 (KfW 70 standard), and an energy performance certificate are included in the building description. The values are difficult for me to understand. The energy certificate specifies "natural ventilation," valid until 2021.
Could someone please help or share their opinion?
Thank you in advance
