Photovoltaic cells are small devices that convert light to electricity. The process starts with sunlight striking the cells, knocking free electrons from the back and causing them to move to the front.
Dry lining can be used to line walls and ceilings in homes and commercial buildings. Unlike plasterboard, dry lining can be applied directly to walls or ceilings, and is often much cheaper.
A trickle vent is a tiny opening in the wall or window frame that lets in small amounts of air. These trickle vents are used extensively throughout the UK and Europe. In some cases, they are even integrated into the window frames themselves. But are they necessary? We’ll take a closer look at this popular ventilation system.
If you’re interested in the quality of insulating materials, you’ll probably have heard of U-Values, which are a popular unit for determining the insulating effectiveness of a building component. While they’re used in the Building Regulations, they are also an important indication of design and build quality. If you’re wondering what they mean, read on to find out more.
SAP calculations are a way of comparing the running costs of dwellings anywhere in the UK. For new dwellings, SAP calculations are a simple desktop exercise, in which a client submits their specifications and plans to an assessor. They should be undertaken early on in the design process, as it can save a costly redesign of the dwelling.
In this article, you will learn how to do the As Built SAP calculation. You will also learn about the On Construction Energy Performance Certificate, Predicted Energy Assessment and Air testing at the As-built stage. All of these factors are vital for achieving a high SAP rating. If you are looking for more information about these topics, check out the following articles. These will help you understand how to do the calculation and ensure that your building meets the current regulations.
SAP stands for standard assessment procedure. The purpose of these calculations is to measure the energy performance of buildings. These calculations are required by the Building Regulations, introduced by the government in 1995, which deal with the conservation of power and fuel.
A curtain wall is an exterior covering that covers windows and other transparent surfaces. The curtain wall’s materials include steel, wood, and fabric. These materials have different thermal conductivity, so the thermal break between the aluminum and the glass must be suitable for the temperature difference between them. A true thermal break is a minimum of 1/4 inch thick, while polyester reinforced nylon or poured and debridged polyurethane is up to 1 inch thick. The insulation layer between the window and the curtain wall should be insulated to avoid heat transfer.
A building envelope is a structure that protects its interior and exterior from external environmental factors. Properly installed, this system reduces stress on mechanical systems, lowers energy bills, and increases resale value. Although a building’s entire envelope is comprised of several components, they work together to achieve a maximum efficiency level. Replacing one part of the system will increase the building’s overall efficiency. Changing all components will increase the building’s efficiency and longevity.
