U7 Designing process

Steps of designing process

1. Get acquainted with location, climate, geological conditions, local sources

2. Write the requirements of client, activities in the building

3. To know the budget

4. According to the budget limit the square footage of the house (size and shape)

5. Make a sketch (diagram) for spaces, connect activities (not each activity needs its own

space, it can be combined), functioning of spaces, include outer spaces and outer

activities

6. Think about the most energy effective source of heating media, heat source, air

exchange and thermal insulation.

7. To think how the energy sources will be connected to the house

8. To reorder the spaces with the mind of thermal zones, heating, sunny zones, effective

water, sewage and air exchange function, also in accordance with suitable shape for the

location.

9. To think about suitable construction and materials, considering local sources.

10. To think about thermal layer (eliminating thermal bridges)

What to think about : Thermal comfort

Light comfort

Quality of air (moisture, O2

content)

Inner surfaces

To solve construction and details of : Foundations

Walls

Roofs

Openings (windows, doors)

Services - sources coming in and out:

energy, water, food

The most difficult think is to make things simple - good design is simple and genuine.

U7 Designing process

House plan: A home designed to respond to site conditions can optimise lifestyle, improve energy efficiency and protect the quality of the natural environment.

It’s all about orientation

• The south side is warmer and sunny in winter and the best place for rooms you use a lot, like living areas.

• The west side gets sun in the afternoon and that is why it is best for children rooms, so that they would have sun in the afternoon, when they come from school.

• The north side has least sun afternoon and is best for rooms you don’t use often, like bathrooms, technical rooms, garages and laundries.

• The east side gets morning sun and is good for breakfast rooms, kitchens and bedrooms

• Orientate your living spaces to the south or including decks and outdoor areas. • Orientate sleeping and utility areas and entrance to the east, west or to the north. • Design for cross-ventilation. • Design for acoustic privacy between living spaces, bedrooms and bathrooms. • Integrate shading measures to control sun penetration during summer including

deep eaves (over 600mm especially on south elevations). • Integrate landscaping for shading as well as providing a green screen for privacy.

Think small The small house can be very functional. Think about activities you do in the house and think about spaces and not rooms. Try to combine relevant activities - it can save a lot of space. Try to avoid making corridors, smart design uses even corridors for other activities. Small is more sustainable, less expensive to build, needs less tidying and less maintenance. Adaptability Good house design also builds in the ability of your house to grow and adapt as your needs change. Think about how your needs might change over time or the different ways in which the rooms in your house can be used for different purposes. Think about including wider corridor and door way widths as well as unobstructed circulation space around your home which makes it easier for everyone to move around.

U7 Reading house plans

How to read lines of house design project - meaning of lines

Project of the house is done in several stages : • idea and concept which is called house study, scale cca 1 : 100, can be a sketch • project of the house, building plan, scale 1 : 100, 1 : 50 • construction project, detailed project 1 : 50, Details 1 : 20 etc. House project usually consist of separate project for all installations (electricity, water and sewage, gass, air exchange, heating and cooling), statics of structure, fire protection etc… It is important to read those project before building, to know all necessary foundation and wall breakdowns and contexts of construction and installations.

visible outlines and edges, intersections of constructions, constructions visible in plans and below the sections visible outlines (edges on connection with air) of plan and section of constructions, visible edges of foundation plan metal reinforcement break line invisible constructions invisible edges of foundation, edge of hight change in foundation axis section line metal reinforcement constructions above section intersections of roof areas (ridges) change of geological layers in section, change of floor finishes

To have the complex overall image of the house design, we need to have :

1. House site – layout with north indication

2. Plan of foundations 3. Plan of first, second….etc.

floor 4. Plan of a roof (view from

above) 5. Several cross sections 6. Views East, South, West,

North

House site – layout with north indication

S2 - House Installations Info Sheet

U7 Heating and cooling

Sources: Preferable are renewable sources of energy: solar, wind, geothermal, biomass, water, biogass, temperature difference Appliances and heat distribution: In well insulated straw bale houses we sometimes need more energy to make hot water than to heat the house, and that is why heating is often connected with production of hot water for the house. In very well insulated SB houses it almost does not matter where is the heating appliance situated. With tripple glass windows it is not anymore necessary to place heating under the windows. In very well insulated houses we can count also with thermal gains from:

• Solar gains from windows • People in the house • Appliances/ fridge, PC....

The means of heat distribution in the house are : Water (through radiators, wall and floor heating) Air (air heating fire place, air heating connected to ventillation system) Fire (through radiating stove mass and stove doors)

Heating



Biomass (wood and plants) heat source:

• Stoves in the room: heavy/semi-heavy/light (depending of mass capacity and thus the firing is every 6,12,24 hours (advantage: visible fire, comfort, healthy; disadvantage: foundation, chimney needed, maintanance needed, everyday manual work, heat spreads mostly in one room and through open doors, mostly are not combined with producing hot water, not fast respond to actual needs)

• Central heating with heater in technical room, heating water (advantage: can be automatic, heating also the water, disadvantage: chimney needed, fire is not visible)

• Open fire-box stove – not reccomended: inefficient use of heat, bad combustion causes pollution, uncomfortable heat distribution

1. air heating fire place, 2. Combined air heating and radiant heat 3. Mass stove

Solar heating:

• PV (Photovoltaics): the panels need space with good south orientation, the batteries to store energy are needed, (disadvantage – not so efficient in cloudy days)

• PV (Photovoltaics) directly heating water • Solar panels: the panels need space with good south orientation

(disadvantage – not so efficient in cloudy days, especially cloudy winters, when it is needed)

Heat pumps:

Heat pumps use the temperature difference of air, water or earth. They work: • Air to water • Geothermal heat pumts: Water to water, Earth to water

Biogass:

Biogass is created by fermenting of organic waste. With biogass we can heat water for use and heating. Reccomendations:



• First we have to think how to save as much energy as possible. • We have to consider local possibilities and sources • It may be more effective to build small independent heat power stations

serving more than one house. Heating (and cooling) in cold climates

• In cold climates it is good to combine solar panels efficient in summer and stove heating efficient in winter.

• In cold climates with hot summers it is good to use heat pump earth to water, because it can be used for efficient cooling in summer

Heating (and cooling) in hot and milde climates

• In milder and warm climates it is good to use solar panels or PV. • In milder and warm climates it is good to use heat pump air to air/water,

because it is more efficient to cool house in summer. The medium of heat distribution in house is :

• Medium and its efficiency to distribute heat: water – is efficient, and you have hot water for use too. It is reccomended to use wall heating system under clay plaster and thus create radiant heat.

• air – is not efficient heat medium but possible for air to air heat pumps • Fire is efficient heat medium – most healthy, radiating heat allows lower air

temperature, while feeling comfortable warm. List of heating devices from the view of healthy inner climate: 1. Heavy mass stove/oven 2. Wall heating (under plaster) 3. Floor heating 4. Open fire-box stove 5. Radiators 6. Air heating fire place 7. Air Heating connected to ventillation system

Air heating fire place Radiating mass stove/oven

Passive shading In north hemisphere in warm and continental climates it is necessary to think about shading the windows when designing the house. It is reccomended to orient windows directly to the south to gain solar heat in winter and to easily shade in summer by bigger roof overhang, fixed or rolled out shading, or balcony etc. It might help to have leaf tree creating the shade. (west and east oriented windows are not possibe to protect by overhang, they tend to overheat house in summer)

Passive night cooling It helps to cool house through open windows at night, if the outside temperature drops down. Cooling (and heating) in mild climates In cold climates it is good to use geothermal heat pump earth – water, because it is efficient for cooling in summer. Cooling (and heating) in hot climates In milder and warm climates it is good to use heat pump air to air („Split unit“ = air conditioning), because it is more efficient to cool house in summer. In well insulated houses, it is possible to run the unit and cool down the house only some time, p.ex. when people are not at home – not to effect their health.

U7 Ventilation

Ventilation is needed to provide oxygen for metabolism and to dilute metabolic pollutants (carbon dioxide and odour). It is also used to assist in maintaining good indoor air quality by diluting and removing other pollutants emitted within a space but should not be used as a substitute for proper source control of pollutants.

Good ventilation is a major contributor to the health and comfort of building occupants. Recommended air exchange nA=0,4h-1 according to EnEV 2002 and DIN4701 V-10 Possibilities to ventilate house:

• Opening windows and doors regularly • Through micro ventilation in windows • Automatic window ventilation • Extract ventilators • HRV (Heat recovery ventilating units)

Ventilation by opening windows increases the energy needed for heating or cooling, however heat recovery ventilation can be used to mitigate the energy consumption. It is possible to gain 75% - 95 % of heat back from exhaust air. Overall heat losses in well insulated house can drop 20-50% when using heat recovery ventilation. Heat recovery ventilation systems/units inventer - decentralized ventilation directly through at least two units mounted in the wall. They work together, switching the opposite direction. Heat recovery is done through ceramic element. De-centralized unit - small unit is usually mounted in the room and serves to one – to max.3 adjacent rooms. Volume of exchanged air is max.100 m3/h (50 Pa). Centralized unit - can be of different size, the heat recovers in one unit and than is distributed in the whole house by tubes, or by cascading system, just through gaps or holes with small vents. Hot air solar panel AIR-INVENT Works only on solar energy, pushing inside the warm air heated by sun in the solar panel fixed on a façade.

U7 Installations

Fixing installation: Cables (sockets) can be fixed by:

• plastic or metal pegs • gypsum, but before you apply earth

plaster it necessary to aplly primer • gypsum-clay morter (1:2) • clay morter (dries very slow)

Sockets can be also fixed with the help of split pin, or board with a pin.

Be aware of airtightness around the sockets! Apply mash/jute in the plaster on cables to prevent cracking.
