Aerator Replacing old, inefficient faucets and taps with new aerators can save the average family 2500 l of water per year, equal to the amount of water needed to take 40 showers. others
Air Chamber insultation - Foam Building enclosures have to meet the waterproofing and insulation requirements, both thermic and acoustic. For this reason, there are enclosures with different sheets; between the inner and outer sheets, which may be made of the same material, there is an air chamber for the purpose of avoiding thermic bridges. It usually (should) incorporates thermic and acoustic insulation. facade
Air Source Heat Pumps In domestic heating use, an ASHP absorbs heat from outside air and releases it inside the building, as hot air, hot water-filled radiators, underfloor heating and/or domestic hot water supply. The same system can often do the reverse in summer, cooling the inside of the house. When correctly specified, an ASHP can offer a full central heating solution and domestic hot water up to 80 �C space heating and tap water
Air heating A heating/cooling distribution system that works through the ventilation system. The air in the ventilation gets warmed or cooled to the desired temperature and is distributed through the house. space heating and tap water
Attic floor thermal insulation The requirement for U-value of refurbished attic floor is 0.17 W/m2K in Hungary. The required thickness of the thermal insulation depends on the exisisting attic floor. roof
Awning With better insulated homes, overheating can become a problem. The sun heats up the inside of the building and the heat is unable to exit the building. Awnings and roller shutters can prevent this partly by blocking out the sun during the summer. others
Balanced ventilation Balanced ventilation for the entire house works with a single ventilation unit that controls the supply and exhaust for the whole house. An equal amount of air is supplied and discharged (hence: balance). You can also make balanced ventilation demand-driven with CO2 or moisture sensors. This automatically determines how much air must be supplied and removed. A demand-driven system is even more energy-efficient. ventilation
Balanced ventilation with heat recovery (HRV) Balanced ventilation for the entire house works with a single ventilation unit that controls the supply and exhaust for the whole house. An equal amount of air is supplied and discharged (hence: balance). You can also make balanced ventilation demand-driven with CO2 or moisture sensors. This automatically determines how much air must be supplied and removed. A demand-driven system is even more energy-efficient.Balanced ventilation for the entire house works with a single ventilation unit that controls the supply and exhaust for the whole house. An equal amount of air is supplied and discharged (hence: balance). With heat recovery the heat from the exhaust air is recycled into the supply air. This saves you energy compared to mechanical ventilation without heat recovery and has an efficiency up to 95%. You can also make balanced ventilation demand-driven with CO2 or moisture sensors. This automatically determines how much air must be supplied and removed. A demand-driven system is even more energy-efficient. ventilation
Basement ceiling External Coating (BEC) Basement ceiling external insulation is used to reduce heat loss through basement floor by covering it with a material that reduces heat transfer. This limits thermal bridges and resuces heating costs floor
Basement ceiling thermal insulation The requirement for U-value of refurbished cellar floor slab is 0.26 W/m2K in Hungary. The required thickness of the thermal insulation depends on the structure of the cellar ceiling slab. floor
Biomass boiler Wood-fuelled heating systems, also called biomass systems, burn wood pellets, chips or logs to provide warmth in a single room or to power central heating and hot water boilers. space heating and tap water
Cable/pipe bushings A house that has bad airtightness often has a lot of trouble with inftiltration. Infiltration is unwanted ventilation of the building, this is the air that comes through seams, cracks and porous surfaces. The older the building the less airtight it often is. The airtightness of the building is just as important as the insulation, because bad airtightness causes heatloss, discomfort and can cause structural problems. others
Cavity wall insulation Cavity wall insulation is used to reduce heat loss through a cavity wall by filling the air space with material that inhibits heat transfer. This immobilises the air within the cavity (air is still the actual insulator), preventing convection, and can substantially reduce space heating costs. facade
Changing of radiators and installation of thermostatic radiator valves The room temperature can be controlled by the radiator valves installed on new radiators. others
Condensing boiler Replacing the existing permanent temperature or low temperature boiler to a condensing boiler. space heating and tap water
Condensing combi boiler Replacing the existing permanent temperature or low temperature boiler to a condensing combi boiler for domestic hot water supply and heating. space heating and tap water
Condensing combination boiler (electric) If you still have separate appliances for hot water and heating (for example, a boiler for hot water and a boiler), consider replacing both appliances in one go with a combi boiler. This saves on your energy bill and is cheaper in purchasing and maintenance. space heating and tap water
Condensing combination boiler (gas) If you still have separate appliances for hot water and heating (for example, a boiler for hot water and a boiler), consider replacing both appliances in one go with a combi boiler. This saves on your energy bill and is cheaper in purchasing and maintenance. space heating and tap water
Condensing gas boiler Gas boilers are central heating systems that act like mini fires, continuously heating water. This heated water is then pumped around the property through pipes and radiators in order to heat space. Condensing boilers are water heaters fueled by gas or oil. They achieve high efficiency (typically greater than 90% on the higher heating value) by condensing water vapour in the exhaust gases and so recovering its latent heat of vaporisation, which would otherwise have been wasted. space heating and tap water
Convectors A convector, often wrongly named a radiator, is a heating/cooling distribution system with a central heating pipe with fins attached. It warms the air through the fins and thus the room. others
Demand driven exhaust-only mechanical ventilation Mechanical exhaust ventilation with natural air supply, driven by CO2, humidity or movement sensors. ventilation
District heating District heating, or block heating, is a type of central heating. You have a central 'boiler' somewhere in the neighborhood (a heat source). The hot water goes to the houses through underground insulated pipes. Via a special 'cabinet' (heat exchanger) you can use the heat for heating and hot water. The used and now cooled down water goes back to the 'boiler' which heats it up again. In renewable heat networks, geothermal heat or residual heat is used. For example from a power plant, factory or data center. If the heat source is sustainable, a heating network will generate a lot of climate gains. space heating and tap water
Door (with glazing) with frame Single pane glazing is no longer of this time, and also ordinary double glazing is outdated. To make the step towards a gas-free future, your home needs at least HR ++ glazing. Triple glazing would be best. With good insulating glass your living comfort improves and your energy bill decreases. Are your window/door frames ready for replacement? Then immediately opt for triple glazing, especially in living area's. This insulates even better than HR ++ glazing and the additional costs are low in relation to the entire investment. windows
Door frame to wall connection A house that has bad airtightness often has a lot of trouble with inftiltration. Infiltration is unwanted ventilation of the building, this is the air that comes through seams, cracks and porous surfaces. The older the building the less airtight it often is.

Electric boiler - SFH As opposed to the typical boilers, an electric boiler operates without using combustible fuel such as oil or gas but rather use electricity to generate heat for your home. Electric boilers are often called Electric Steam Boilers, as they produce steam from electricity for heating purposes. This system is highly efficient thanks to the conversion of electricity into thermal energy that produces an almost 100% efficiency rate. However, it depends how the electricity is generated�whether the electricity generation is efficient or not will influence your conversion efficiency rate others
Exhaust-only mechanical ventilation Exhaust only mechanical ventilation continuously refreshes air in the house. It pulls the air from the house through several exhaust points throughout the house and expells the air the air outside. Fresh air enters the house through grilles and windows. Exhaust only mechanical ventilation creates a healthier living environment compared to natural ventilation. The step from natural to mechanical ventilation results in slightly higher energy consumption (but that is not a waste ). ventilation
External insulation - Panel External thermal insulation are a means of applying insulation materials to the outside of a building with the primary aim of improving thermal performance although other benefits generally result too. Overlay is appropriate where the existing deck is sound and where the waterproof membrane is aged. Either a new membrane is placed over the existing complete with insulation and ballast (inverted warm) OR the existing membrane is prepared as a vapour check and insulation is added complete with a waterproof membrane over (warm). facade
External insultation - ETICS External thermal insulation composite systems � ETICS for short � are a means of applying layers to the outside of a building with the primary aim of improving thermal performance although other benefits generally result too. Overall benefits include: a reduction in heating and air conditioning running costs; increased internal comfort; a reduction in condensation where this has been present; improved weather resistance; better external appearance when added to an existing building; no internal disruption to the structure or its inhabitants. ETICS can be used on existing solid-walled construction and narrower cavity walls no matter if these are partly or completely filled with insulation. facade

Ground Floor Internal Coating (GIC) Ground Floor Internal insulation is used to reduce heat loss through ground Floor by covering it with a material that reduces heat transfer. This limits thermal bridges and resuces heating costs floor
Ground Source Heat Pump Ground source heat pumps (GSHPs) use pipes that are buried in the garden to extract heat from the ground. This heat can then be used to heat radiators, underfloor or warm air heating systems and hot water in your home. It circulates a mixture of water and antifreeze around a loop of pipe, called a ground loop, and since the ground stays at a fairly constant temperature under the surface, the heat pump can be used throughout the year. space heating and tap water
HR+++ glass (triple glazing) Insulating glass (IG), more commonly known as double glazing (or double-pane, and increasingly triple glazing[1]/pane), consists of two or three glass window panes separated by a vacuum or gas filled space to reduce heat transfer across a part of the building envelope. windows
Heat Recovery System Heat recovery systems can come in a variety of forms, but all involve some form of heat exchanger. This sits in the building, usually in the loft or on the roof, and pipes feed down from it into each room, drawing out the stale air and replacing it with warmed, clean air. others
Heat pump a/w A fully electric heat pump replaces your gas-fired boiler and is suitable for houses with good to very good insulation. A heat pump extracts heat from the air, soil or groundwater and uses it for central heating and to heat tap water. A heat pump should be combined with a low temperature heating system, for example underfloor or wall heating, and has a storage tank for hot water. The general heat pump is about the size of a refrigerator and consists of two parts, an outdoor part to extract heat from the air and an indoor part for central heating and tap water. cooling system

Installation of thermostatic radiator valves The room temperature can be controlled by the radiator valves installed on the existing radiators. others
Insulating against the underside of the existing floor Most houses have a crawl space of 35 centimeters or higher, making it easy to insulate the bottom of the floor. This is done with thermo cushions, EPS, sheets of wood or flax, glass or rock wool. The insulation company needs half a day to day to place the insulation material and clears everything neatly. The work takes place under the floor. floor
Insulating inside the envelope With insulation on the inside of the envelope, your outer wall is thickened with (extra) insulation material. The fa�ade will remain the same, but you will lose space on the inside of the home. Insulation on the insnide of the envelope is always allowed, you don�t need a permit from the municipality to be able to do this. facade
Insulating outside the envelope with cavity With insulation on the outside of the envelope, your outer wall is thickened with (extra) insulation material. The fa�ade will be finished as you wish, for example with brick slips, stucco, wood or fa�ade panels. Insulation on the outside of the fa�ade is not always allowed, you also need a permit from the municipality to be able to do this. Exterior wall insulation is a more expensive option to insulate your fa�ade. But it offers many other advantages: you can apply a thicker insulation layer, which gives you more comfort and savings.

Insulating the bottom of the crawlspace If it is not possible to insulate your floor at the bottom, soil insulation is an option. In this case, spheres or pieces of styrofoam (EPS or biofoam beads or EPS chips) are sprayed into the crawl space via a hose. This can be done via the crawl hatch or through a temporary hole in the wall (if there is no crawl hatch). With an attachment on the hose you get deeper into the crawl space and the material can be well distributed over the bottom. The installation of soil insulation usually takes a day. Soil insulation is less effective than insulation at the bottom of the floor. With soil insulation you get the maximum level of 'Good floor insulation', even though the insulation layer on the bottom is 20 cm thick. Soil insulation is not suitable for combining with underfloor heating in the future. Advice: choose only soil insulation if you do not have crawl space or if your crawl space is lower than 35 centimeters. floor
Insulation in the ceiling/attic floor Insulating your attic floor gives the same saving benefits as insulation on the outside of your roof. The condition is that you do not use the attic as living, working or sleeping space and you can close it with a hatch or door. You can also perform this job yourself if you are handy. roof
Insulation on top of the existing roof With this type of roof insulation, the roof tiles have to be removed and insulation material is placed on the roof from the outside. This is a job for a professional: the roof gets higher and the connection with the roof gutter has to be made again. Roof insulation on the outside is best done when you renovate your roof. roof

Night ventilation During hot summers, the ventilation system can be turned on if the outside temperature is lower than the inside temperature during the night. A balanced ventilation system uses its bypass to blow the cool air into the home and lowers the inside temperature. others
Nok A house that has bad airtightness often has a lot of trouble with inftiltration. Infiltration is unwanted ventilation of the building, this is the air that comes through seams, cracks and porous surfaces. The older the building the less airtight it often is. The airtightness of the building is just as important as the insulation, because bad airtightness causes heatloss, discomfort and can cause structural problems. others
PCM PCM, or phase change materials, are materials that store heat at a certain temperature. PCM allow to store excess heat inside the home during hot summers, saving on cooling. The materials have a certain temperature at which they will absorb heat, for instance 23 degrees, and when the room temperature rises above that temperature the PCM will absorb any excess heat. The PCM releases the heat when the building temperature drops below the working temperature of the PCM, most often during the night when it is easier to cool the home. others

Depending on the amount and location of fenestration, reductions in annual cooling energy consumption of 5% to 15% have been reported sun flow
Shower heat (recovery) exchanger A lot of heat disappears through the shower drain. This heat can be used to preheat the cold water before it enters the boiler, which in turn needs to work less hard to heat the water. The heat exchanger is placed under the shower tray, in the floor of the walk-in shower or in the drain pipe. This is a good energy saving option, especially when you are renovating your bathroom. others
Solar collector Solar panels provide electricity, solar boilers provide hot water. A solar water heater is an environmentally friendly alternative to natural gas: when using solar energy, no CO2 is released and you have an infinite supply of energy. A household with 4 people saves about 180 m3 of gas and 330 kg of CO2 emissions annually with a solar boiler. In the summer, your solar boiler supplies almost all of your hot water. This does not work in the winter, not even with a large solar boiler. But you do not have to be afraid of a cold shower: if there is less sunlight, your combi boiler or heat pump will provide hot water. others
Solar panels Solar panels can deliver a large part of your electricity in a sustainable way. Sunlight is inexhaustible and when converting sunlight into electricity no greenhouse gases or harmful substances are produced. Solar panels are placed on your roof in one day. You do not need to apply for a permit for the placement. Check with your energy supplier beforehand whether your meter box is suitable for solar panels. others
Solar thermal Solar thermal panels use the sun to heat up water. The way a solar thermal panel works is quite simple. It absorbs the heat from the sun with panels that are called collectors. The heated water or heat-transfer fluid then runs from the collectors to your hot water cylinder. This way a solar thermal system can provide your home with free heated water. The use of such a renewable energy source has numerous advantages, among them the money saved on energy bills, the reduction of your carbon footprint and the low maintenance, making solar thermal a great investment. others

Wall External Coating (WEC) External wall insulation is used to reduce heat loss through wall by covering it with a material that reduces heat transfer. This limits thermal bridges and reduces heating costs facade
Wall Internal Coating (WIC) Internal wall insulation is used to reduce heat loss through wall by covering it with a material that reduces heat transfer. This limits thermal bridges and reduces heating costs facade
Wall heating A low temperature heating system where heating pipes are placed in the wall, thus making the walls the heating/cooling distribution system. others
Water saving faucets You avoid unnecessary water coming out of the tap with water-saving nozzles and flow restrictors. Most new faucets already have volume limiters. In the store you can recognize energy-saving taps to volume flow class Z. Thermostatic mixing taps also help, because they provide water at the right temperature faster and easier - so less water is flushed down the drain. Mixing taps with one handle that do not give hot water up to half of the turn also save gas because they prevent you from mixing hot water unnoticed. others
Water saving showerheads A water-saving showerhead uses less water and head for showering. It provides the same amount of shower comfort, but saves 20 percent on water and energy consumption compared to a standard showerhead. If you exchange a rain shower (extra large shower head) for a saving shower head, you can save up to 60 percent! An average household (2.2 people) annually saves 7500 liters of hot water and almost 45 m3 of gas. The savings will be even higher if you shower for more than 9 minutes, you use an (inefficient) rain shower or comfort shower. others

Window frame to roof connection A house that has bad airtightness often has a lot of trouble with inftiltration. Infiltration is unwanted ventilation of the building, this is the air that comes through seams, cracks and porous surfaces. The older the building the less airtight it often is. The airtightness of the building is just as important as the insulation, because bad airtightness causes heatloss, discomfort and can cause structural problems. others

air-to-water Electric Heat pump - SFH Air to water heat pumps can provide efficient heating and cooling for your household, especially if you live in a moderate climate. After proper installation, an air to water heat pump can offer from one and a half up to 3 times more thermal energy to a home than the electricity it spends. This can happen due to the fact that the heat pump transfers heat, rather than transforming it from a type of fuel like regular combustion heating systems do. others
