However, air-source heat pump takeup in the UK is among thelowest in Europe. The upfront cost may seem like an obvious reason why. Even with the grant, installing an air-source heat pump can costthousands of poundsmore than a new boiler. The government could arguably increase the subsidy....
To realize zero energy buildings, photovoltaic-thermal (PVT)–ground source heat pump (GSHP) systems are being developed. However, the PVT–GSHP system faces challenges in urban areas or in existing buildings owing to the complicated installation process and high initial cost. To address this pro...
2023, Building and Environment Citation Excerpt : HEPA-PAC units are highly effective in reducing expiratory particles and offer greater convenience compared to other PAC types like ION-PAC and UVGI-PAC [92]. It was found that HEPA-PAC should be placed far away from the contaminant source [46...
and water depletion (which is more sensitive to the technology type than the heat source). Sorbent-based DACCS exhibits a lower environmental impact profile using biomethane for heat. The only increase compared to the heat pump derived heat is terrestrial acidification, which is mostly driven by t...
Ship engines are a significant source of anthropogenic combustion emissions, such as nitrogen oxides (NOx), sulphur oxides (SOx), particulate matter (PM), carbon monoxide (CO), and volatile organic compounds (VOCs). This is a major concern especially for coastal communities [e.g. Aakko-Saksa...
Fig. 5. Ventilation radiators with exhaust heat pump heat recovery. The EAHP system with VRs has also been actively used (35% in second grant period) in apartment building renovation. During the first grant period, fresh air inlets were used to supply air, but due to many negative reports ...

The common heating methods in rural houses in northern Shanxi, China, are coal-fired boiler radiator heating, air-source heat pump radiator heating, and Chinese stove–kang heating. Many households in other rural areas of northern China also use these three heating methods for heating. However, ...
Building energy savings and occupant thermal comfort are the main issues in building technology. As such, the development of energy-efficient heating, ventilation, and air-conditioning (HVAC) systems and the control strategies of HVAC systems are emergin
In this model, the thermal resistance, capacitance, thermal conductivity and heat gain are represented in the electrical network by a resistor, capacitor, voltage source and current sources. Rconv is the convection resistance; Rcond_t1 and Rcond_t2 are the conduction resistance at temperatures t1,...
