TGD L 2011 – 0.5 – DEFINITIONS
0.5 DEFINITIONS For the purposes of this Technical Guidance Document the following definitions apply: – Energy Use (for a particular purpose, e.g. space heating, water heating, cooling, ventilation, lighting): Energy input to the relevant system to satisfy the relevant purpose. Delivered Energy: Energy supplied to the dwelling and its systems to satisfy the relevant energy […]
TGD H 2010 – 1.2.2.7 – Branch pipes
1.2.2.7 Condensate drainage from boilers should be connected to wastewater pipework. The connection should be made using pipework of a minimum diameter of 22 mm. If an additional trap is provided externally to the boiler to provide the 75 mm seal, an air gap should be provided between the boiler and the trap. The pipe […]
TGD J 2014 – 5.5.2.1 – Fire safety:
5.5.2.1 Fire safety: With automated fuel feed systems, there is a risk of fire burning back from the boiler to the fuel store. To prevent this, there should be an interruption to the fuel-transport system (e.g. a star-feeder or chute for the fuel to fall into the boiler). For large biomass systems, e.g. community systems, […]
TGD L 2011 – 1.2.3 – RENEWABLE ENERGY TECHNOLOGIES
1.2.3 In the case of electrically powered heat pumps, only energy in excess of 2.5 times the electrical energy directly consumed by the heat pump can be counted towards meeting the minimum level of energy provision from renewable technology. In the case of systems based on biofuels or biomass, appliances must be designed to run […]
TGD L 2008 – 1.3.5.2 – Building Services, ARTIFICIAL LIGhTInG
1.3.5.2 General purpose artificial lighting systems shall be designed and controlled so as to ensure the efficient use of energy for this purpose. The efficiency of a general lighting system may be considered acceptable if it complies with one of the following: (a) 95 % of the artificial lighting capacity in circuit Watts is provided […]
