We have never spent more time in our own homes than we have in the past twelve months. It is no surprise then that consumer spending on home improvements is one sector that continues to experience growth, along with digital entertainment and consumer electronics. At the same time, 2020 has been a wakeup call for many to protect our planet. Tackling the climate emergency continues to gain ...
Air source heat pumps and ground source heat pumps work along very similar lines. ...
Executive Summary Ground-source heat pumps (GSHPs) are typically the most efficient form of heating and cooling for buildings. For every unit of electricity a GSHP system consumes, it produces roughly 3-4 units of equivalent heat (or cooling), thanks to the solar energy naturally stored ...
This large domestic property in the tiny hamlet of Bircher was dependent upon oil for its heating and costs were rising year after year. The owners decided to investigate the options for reducing the costs of keeping their house warm especially after a particularly cold, and expensive, winter ...
We need to change that mindset and make people aware that we’re standing on vast resources of geothermal heat, wherever we are in the world. When it comes to geothermal, there are hurdles in people’s minds. ...
Is your home suitable for an air source heat pump? Air source heat pumps are not suitable for every home. ...
Ground Source Heat Pumps are energy-efficient HVAC systems usually adopted in residential and commercial buildings. ...
This case study looks at a ground source heat pump being installed in London. A Ground Source Heat Pump was chosen as a sustainable and energy efficient way to provide 100% space heating and hot water for this 550m2 new build eco-house in East ...
Impacts of Shallow Geothermal Energy on Groundwater Quality provides a hydrochemical and geomicrobial overview of the effects of ground source heat pumps and aquifer thermal energy storage. The area is investigated with field and laboratory experiments, and reactive transport models, showing that shallow geothermal energy systems ...
Denmark, a pioneer in the field, has a target of achieving all its electricity and heating needs from renewables by 2035, and all energy sectors − including transport − by 2050. This includes an expansion of wind and solar power, biogas, ground source heat pumps, and wood-based biomass. Because of its ...
— Hydronics and VRV. A geothermal ground source heat pump system was installed to serve the second floor, and a VRF system with multiple zones was installed to serve the ground floor. ...
Technical Matters- sample energy-saving actions: Removing or disabling light fittings in areas with excessive lighting Replacing incandescent and halogen lights with more energy-efficient CFLs Installing 7-day timers on office equipment (photocopiers, printers) Installing 7 day time clocks on water boilers Installing motion sensors or daylight sensors in toilets and other appropriate areas ...
As part of the alterations the owner wished to improve insulation and replace the existing heating and hot water system, which was provided by two 2,000 litre LPG tanks using approximately 12,000 litres of LPG per yea. Alternative energy sources were investigated, including ground source heat ...
In this paper, the thermodynamic modelling of exergy loss, exergy efficiency, exergy destruction rate, environmental destruction coefficient, improvement potential, exergy destruction factor, relative irreversibility, productivity lack and exergetic factor of ground source heat pump (GSHP) system are investigated. The results ...
Natural stone, for example, produces minimal emissions during the production process but the transportation from the source to manufacturing site can be the largest cause of emissions, e.g. in transporting from quarries in India. ...
It features many sustainable techniques in its own design including photovoltaics, micro wind, sedum roof, e-glazing, natural lighting and insulation, green floor coverings, mini combined heat and power (CHP), rainwater harvesting, biomass, ground source heat pumps, engineered timber, low energy lighting, ...
At the Isle of Grain, National Grid uses waste heat from an EON CCGT to warm the LNG and make it into natural gas for injection into the gas grid. ...
The use of bio-fuels for heating and lighting pre-dates the use of fossil fuels by thousands of years. ...
Instead the report finds carbon reductions in switching out common home devices that use fossil fuels with those that use electricity.EPRI looked at household activities that use energy: clothes drying, heating, cooling, cooking, warming pools. It then found electric technologies that allow us to perform these activities with less fossil fuel use; a heat ...
High exergetic efficiency due to a close temperature tie between geothermal energy and district heating and cooling was noted. Parameters governing the rational use and management of geothermal energy systems with special emphasis on integrated-cascaded district energy systems were formulated and explained with two case studies.Keywords: geothermal energy, district ...
