Air source heat pump (hybrid) AIR_SOURCE_HEAT_PUMP_HYBRID
A hybrid heat pump is a heat pump that works in conjunction with a central heating boiler. In most cases, an existing central heating system is expanded with a heat pump. The hybrid heat pump consists of an indoor and outdoor unit, whereby energy is extracted from the outdoor air through the outdoor unit of the hybrid heat pump. The working part of the heat pump takes this energy to a higher temperature level for the heating in a building. In addition, the central heating boiler provides hot water in the bathroom and kitchen. The central heating boiler jumps in for heating only when it is very cold outside.

Battery energy storage BATTERY_ENERGY_STORAGE
A battery energy storage system stores self-generated solar energy so it can be used at times when solar panels are not producing electricity, such as in the evening or on cloudy days. This increases on-site energy consumption, lowers energy costs, and reduces dependence on the electricity grid. This measure is only effective when combined with solar panels, as the battery is charged with the energy you generate yourself.

Condensing boiler for heating CONDENSING_BOILER_HEATING
A condensing boiler produces hot water in an energy-efficient way and is designed to guide the supply of cold water through flue gases. The boiler obtains additional heat from the flue gases through condensation of the water vapour present in these flue gases. This generates up to 10% more heat than a conventional boiler. The cold water absorbs this heat from the water vapour, which means that less gas is needed to produce the same amount of hot water for the central heating system.

Daylight and motion sensors for outdoor lighting OUTDOOR_LIGHTING_SENSORS
Outdoor lighting is usually operated by a twilight switch, which keeps the lights operating continuously in the evening or during the night. When lighting is required during the night, e.g. to prevent break-ins and vandalism, it is possible to save energy by using a twilight switch and a motion sensor to operate this lighting. The site can then only be illuminated when daylight is insufficient, and someone is close to the motion sensor.

Electric boiler ELECTRIC_BOILER
An electric boiler is a system that produces domestic hot water using electric resistance heating instead of combustion. It converts electrical energy directly into heat through heating elements immersed in water, which is then stored in a boiler tank for use. Because it generates heat directly from electricity without relying on fuel combustion, it is simple to install and operate, though less energy-efficient than systems that move heat, such as heat pump boilers.

Heat recovery ventilation HEAT_RECOVERY_VENTILATION
When heating a building without heat recovery, the air handling unit uses large quantities of fresh and cold outside air to ventilate and heat the building. This cool air is heated up to the desired temperature. At the same time, the same quantity of warm inside air is lost, which causes unnecessary energy loss. A ventilation system with heat recovery re-uses the energy from the discharged air to heat the fresh air entering the building.

Hydronic balancing of central heating system HYDRONIC_BALANCING_OF_CENTRAL_HEATING_SYSTEM
Hydronic balancing involves balancing a central heating system by distributing the hot water correctly across the radiators. Many central heating systems have not been hydronically balanced. This means that the radiator closest to the central heating boiler receives the hottest water, the fastest. The radiators further away from the boiler receive little heat, creating an imbalance. The advantage of hydronic balancing is that it reduces gas bills and increases comfort levels.

LED billboard lighting LED_BILLBOARD_LIGHTING
Highly concentrated lighting is often required for billboards. Because it is a point source, LED lighting can be directed very effectively at a specific area by placing a small mirror behind the light. Unlike fluorescent lighting, LED lighting radiates more light when it gets cooler. The use of LED lighting is, therefore, the preferred option for outdoor advertising purposes. LED lighting can be switched on and off, which if done efficiently, saves more energy.

LED field lighting LED_FIELD_LIGHTING
Due to the high light output at low power, LED is more energy-efficient than conventional flood lighting. Also, LED lighting can be switched off when a sportsfield is not being played on for a while; no cooling down and warming up period is required. That means the lights can be switched on and off anytime. The savings can further increase by dimming the lighting. In that case, the guidelines provided by the sports association for that type of competition or training should be followed. Often a new control system is installed to make optimal use of these benefits.

LED lighting instead of incandescent bulbs LED_LIGHTING_INSTEAD_OF_INCANDESCENT_BULBS
An LED lamp consumes 60% to 70% less electricity than an incandescent lamp for the same light output. LED can replace an incandescent lamp if sufficient space is available in the light fitting. LED lamps are relatively expensive to buy but soon become cheaper because they have a considerably longer service life than incandescent lamps. As a result, it is worthwhile replacing incandescent lamps in buildings with 200 to 500 operating hours per year.

Reduce hot water temperature (ECO) REDUCE_HOT_WATER_TEMPERATURE
Hot water systems do not achieve maximum efficiency if the settings are set incorrectly. For example, hot water supply is often set at a higher temperature than needed, resulting in unnecessarily high energy consumption. Lowering the temperature of your hot water is a simple way of achieving savings on energy costs. However, you have to take care of maintaining a minimum temperature of 60°C to avoid the risk of legionella formation.

Replace air-cooled chiller with water-cooled chiller COOLING_WATER_COOLED_CHILLER
Water-cooled chillers use water instead of air to provide condenser cooling. The efficiency of water-cooled systems is typically higher because of the higher heat capacity of water compared to air. A water-cooled system is the preferred option when reducing operating costs is of paramount concern and the project can afford to invest in a system with a longer payback period. Water cooling involves a higher investment since both a chiller and a circulating tower system are required, which require additional pumps, piping and tanks. Water-cooled chillers are commonly used in large commercial buildings, data centres and industrial processes.

Reverse cycle airco REVERSE_CYCLE_AIRCO
A reverse cycle airco is a system that can both cool and heat a space using the same technology. It works like a heat pump: in cooling mode it removes heat from inside the building and releases it outside, while in heating mode it reverses the process and extracts heat from the outside air to warm the interior. Because it moves heat instead of generating it directly, it is much more energy-efficient than traditional electric heating. Reverse cycle airco systems can be either ductless (serving individual rooms) or ducted (distributing air through ducts to multiple spaces).

SmartWindows SMART_WINDOWS
Physee is a supplier of various systems for windows (PowerWindow, SmartWindow, EESY and SKIN). SmartWindow technology consists of spacers equipped with solar cells and sensors, power storage and communication system and a connection between the various façade elements (such as windows, sun blinds, ventilation, lighting). With this technology, shading becomes intelligent and autonomous. This optimally saves on cooling energy in combination with sufficient daylight (saving on lighting): the blinds only go down when necessary. Existing (automatic) sunblinds can be connected to this. If there is no sunblind, integrated blinds can be placed between the windows.

Installing a buffer tank in a heating system with a (hybrid) heat pump increases thermal storage capacity, allowing the heat pump to operate for longer periods and more efficiently with fewer on/off cycles and less reliance on the gas boiler. This can improve the seasonal performance (SCOP) and shift part of the heating demand from gas to electricity, reducing overall gas consumption. At the same time, the buffer tank introduces additional standby heat losses and increases electricity use due to the higher share of heat delivered by the heat pump.

Switch off or reduce humidification REDUCE_HUMIDIFICATION
Adiabatic humidifiers are often used in offices with balanced mechanical ventilation. The humidifiers are typically set to maintain a moisture level of around 50%. People can work comfortably in environments with moisture levels between 30% and 70%. Throughout the year, the humidity rarely drops below 30%. In most cases, when employees report issues like dry eyes, the cause is usually another factor, such as dust. Since humidifiers consume significant energy, reducing humidification or even turning it off completely can be an efficient energy-saving solution.

Time switch on ventilation system TIME_SWITCH_ON_VENTILATION_SYSTEM
Energy might be consumed unnecessarily if the ventilation system is switched on while the building is not occupied. A time switch can be used to switch off a mechanical ventilation system. If you use a switch that has been set with a weekly programme, you can respond to varying working hours in a building. An overtime timer is used for occasional variations in business hours. This allows the staff to switch the ventilation on themselves for a certain amount of time. This kind of timer operates as a sort of kitchen timer. The ventilation switches off again at the end of the set period.

Time switches on coffee machines TIME_SWITCH_ON_DEVICES
In many buildings, devices such as coffee machines and printers are on when not in use. The equipment also consumes energy when in sleep mode. When time switches are used, equipment is switched on and off automatically, thereby preventing unnecessary energy consumption.

Wall insulation WALL_INSULATION
Buildings with double-brick walls and an air cavity can often be insulated by filling the cavity with materials such as polystyrene beads or foam. The air cavity’s width varies, and insulation is typically applied by drilling small holes in the mortar and injecting the material. The effectiveness of the insulation depends on the cavity width.
For solid walls, insulation can be applied either internally or externally. Each option has its benefits and challenges: internal insulation reduces interior space and requires careful moisture management, while external insulation can be more costly and requires precise workmanship to avoid issues caused by weather conditions.

Weather compensation on heating system WEATHER_COMPENSATION_HEATING_SYSTEM
You can optimise a heating system by fitting weather-dependent controls or setting dead zones. Weather-dependent controls ensure that the inlet temperature is governed by the outside temperature, saving energy on the production of heat. Setting dead zones means that the indoor temperature will increase somewhat in the event of elevated outside temperatures so that less cooling is required. Cooling and heating are also better coordinated.

Weather dependent controls on central heating groups WEATHER_DEPENDENT_CENTRAL_HEATING_GROUPS
The amount of heat required in a building depends on the outside temperature. When the outside temperature is low, the water of the central heating needs to be hot enough to ensure that sufficient heat is emitted to keep the building pleasantly warm. When outside temperatures are higher, a lower central heating water temperature will suffice. A weather dependent control ensures that the temperature of the supply water is geared to the outside temperature. The efficiency of the central heating boiler is increased by allowing the water temperature to drop automatically as the outside temperature rises. This also ensures that the rooms in the building are heated more evenly.

White roof coating WHITE_ROOF_COATING
Dark covering of flat roofs can reach surface temperatures of up to 80°C during periods of sunlight. White coating reflects sunlight, preventing the absorption of heat. This saves on energy costs and reduces the temperature of your roof by more than 40°C.
Not only does this cool down the building, but it also helps combat urban heat island effects in a simple way. This increases comfort and reduces the energy usage of items like air conditioners and fans. Additionally, it enhances the efficiency of any installed solar panels, as they are less likely to overheat. White coating is a seamless liquid sealant made from durable silicon and is suitable for various types of roofing.
