Zero Energy Buildings

A zero energy building (ZEB) produces enough renewable energy to cover its own annual energy consumption requirements, in that way decreasing the use of non-renewable energy in the building sector.

ZEBs use all cost-effective measures to reduce energy usage through energy efficiency and comprise renewable energy systems that produce enough energy to meet remaining energy needs. There are a number of long-term benefits of moving toward ZEBs, including less environmental impacts, lower functional and maintenance costs, better resistance to power outages, natural disasters, and improved energy security.
Reducing building energy consumption in new building construction or renovation can be achieved through numerous means, including complete design, reduced plug loads etc. Reduced energy consumption renders it simpler and less expensive to meet the building’s energy needs with renewable sources of energy.

Zero-energy buildings are built with meaningful energy-saving potentials. The heating and cooling loads are reduced by using high-efficiency equipment, added insulation, natural ventilation, high-efficiency windows, and other techniques. These characteristics differ depending on climate zones in which the construction occurs. Water heating loads may be reduced by using heat recovery units on waste water, and by using solar water heating, and high-efficiency water heating equipment. In addition, day lighting with skylights or solar tubes can supply 100% of daytime illumination within the home. Night time illumination is usually done with LED lighting that use 1/3 or less power than incandescent lights, without adding undesirable heat. And various electric loads can be lessened by choosing efficient appliances and minimizing phantom loads or standby power.

ZEBs have a huge opportunity to modify the way buildings use energy and there are an increasing number of building owners who want to achieve this goal. Private commercial property owners are interested in developing ZEBs to respond their corporate goals, and some have already constructed buildings designed to be zero energy.

Swimming Pool Structure Brief

Life is better by the pool!

Swimming pools cool us down during the hot summer days as well as enhance our garden and increase the value of our property.

Before you decide to build your pool, we would like to take you through different types of construction options you might want to consider.

A swimming pool consists of 3 major components:
1. The shell
2. Finishing or membrane
3. Filtration equipment

1. The Shell
The shell type depends on the type of the pool. If your pool is of a skimmer type, then the shell can either be of concrete with mesh reinforcing, a PVC LINER finishing, or a concrete shell with re bar reinforcing. This option requires waterproofing and tiles (normal or mosaic) and is more expensive than the liner option. A liner pool can also have a prefabricated aluminum shell, which saves time in the construction process.
Generally if your pool is an overflow type it has a concrete shell with reinforcing. The overflow system can have a channel and grill system, a vanishing edge feature, or combination of both. An over flow pool can also be done with liner. The construction of an overflow type pool is generally more expensive than a liner pool and it will also require more maintenance.


2. Finishing
A swimming pool with PVC Liner is the most popular and most economic option. The liner comes in variety of colors and patterns. It is welded on site and if maintained correctly it can last a life time. It is also a lot cheaper to maintain and replace compared to other options.
A tiled pool is more expensive, but a lot more attractive. This type of pool also needs to be water proofed and if damage occurs it is more costly to repair.


3. Filtration equipment
A swimming pool system consists of the pump which circulates the water it draws from the drain, and skimmers / overflow (acts as skimmer). It passes it through the filter (sand / glass media), or cartridge which cleans the water and recirculates it back to the pool via the inlets. The pump can either be (i) Electric or (ii) Photovoltaic* which has zero running costs. As a rule of thumb a pool pump should circulate the water every 4 hours and 2 water changes are required per day. The pool water is kept free of bacteria by the addition of chlorine and acid, or by salt chlorination which produces chlorine via an electronic cell. This is softer than normal chlorine and does not have the smell of chemically produced chlorine. Pools can also be sanitized with ozone generators or ultraviolet sterilization.

*Photovoltaic pumps
– Solar water pumping offers a welcome alternative to fuel-burning generators for pumping and irrigation applications.
– Pumping systems are available and can be designed for small, medium and large scale water demands.
– Solar electric powered pumping is extremely effective. Maximum pumping power is available on sunny days when water is more necessary.
– They have good long term efficiency and credibility. They are pollution free, corrosion-free, self-lubricating and noiseless.

New Products by Lorentz

Members of our company attended the Head of Loretnz in Hamburg, Germany for the three-day presentation of new and upgraded products ( PS2 & PSK2 Hybrid Controls ).


Who is Lorentz: Lorentz are the pioneers for over 20 years in photovoltaic water pumps. The Lorentz technology uses solar energy for water pumping for maintaining and enhancing life for millions of people, their animals and their crops worldwide. This is why their motto is

‘’Sun – Water – Life ‘’


PS2 Control : the PS2 Control is the new and upgraded version of the previous control that we all know. The new PS2 Control is very simple and easy to install and now they have the method of Bluetooth with which the consumer can monitor the operation of the Control via Bluetooth and to make the necessary arrangements so that the installation can become more efficient on the basis of needs. They may also monitor the operation of the installation via the Internet thanks to the new Lorentz Monitoring control. The PS2 Control can operate and during the night time by using Electricity by Network (EAC) by installing the AC Power Pack Control.



PSK2 Control Hybrid: The PSK2 Control Hybrid is the brand new control of Loretnz. The PSK2 Control Hybrid can combine the power from the Network ( EAC ) and from generator, but always with core the Solar Energy. With the method of Bluetooth, consumer can monitor the operation of the Control via Bluetooth and to make the necessary arrangements so that the installation can be more efficient on the basis of needs. In case of night or reduced solar energy, the PSK2 control can complete the required energy needed by the system through the network (EAC) or generator buy it self, therefore also called Hybrid

Renewable Energy – Hybrid Solar Inverter

Hybrid inverter is a new generation of inverter exclusively for solar applications using renewable energy for home consumption, notably for solar photovoltaic installations.

An ordinary solar inverter’s main job is to convert DC power generated from the array into usable AC power. Hybrid inverters go a step further. The function of a Hybrid inverter is allowing selection and orientation of renewable energy, energy from the grid and energy storage based on consumption. This type of system solves issues renewable energy alterability and untrustworthy grid structures.

This system also allows choosing whether electricity from photovoltaic panels should be stored or consumed through an internal intelligent apparatus control unit. This is possible through a technique that adds different energy sources (on-grid) and the administration of stored electricity in the battery (off grid technology). Hybrid inverters consequently operate on grid (grid-tie) as well as off-grid, hybrid (both on-grid and off-grid at the same time) and Backup in case of a black out.

Solar Pump

Solar Swimming Pool Pumps

A Solar powered pool pump reduces your pool pumping cost completely from your household electricity bill. The DC pool pump and controller is added to your filtration system and a solar panel system to your roof so your pool pumping became a zero cost powered by the sun! During the summer swimming season, your pool requires more pumping and naturally with more hours of sunlight, your solar pump will put in the work needed to keep your pool in a good condition. The system is so efficient that it will continue to run even on partially cloudy days.

Moreover A/C pump is available for backup, if you still need more pumping power or need to run your pump at night, simply turn on the pump already installed on your pool for extra hours.

Solar Panels in Cyprus

Solar Panels Cyprus

Cyprus is the European country with the most sunshine all year round and this is exactly the reason why Solar panels are probably the best investment nowadays, offering a quick return on the original investment.

The sun is probably the only energy that someone can invest in without any operational and with minimum maintenance cost.

Solar panels take their name “Solar“ due to the fact that they are using light available from the sun which is then used to produce electricity. They are also known as “photovoltaic” meaning “light – electricity”.

The Solar panel is an area of multitudes of small solar cells. The methodology behind a solar panel is simple: the more light that a cell gets, the more electricity is produced, and drops down to no electricity when there is no sunshine.

Nowadays solar panels in Cyprus provide 13% of the total needs for electricity of the Island. They are used in various ways, including but not limited to:

1) Autonomous system with batteries to store electricity, for swimming pool circulation of the pool water and for irrigation / agricultural purposes using zero electricity.

2) Connected to the grid, where the production of electricity is paid to the producer on a pre-agreed tariff.

3) NETT metering where the production is subtracted from the electricity bill at the end of each month.
