Learner Level: Technical. This document investigates different heating systems, looking at their advantages and disadvantages, their running costs, and what we can do to optimise heating systems, particularly during installation.
Learner Level: Technical. How to make a building more airtight and why this is a good idea. What problems can this create, and how do we overcome these problems? Ventilation is key to reducing heat losses and providing fresh air.
Learner Level: Technical. This document looks at the different types of windows and doors available and the relative impact of each on the energy efficiency of your building.
Learner Level: Technical. How does insulation work? How much money does it save? And how can we make the most of any project to install insulation in our buildings? This document will look in depth at insulation in community buildings.
The Community Buildings Hub is a suite of guides, tools and resources, supported by live discussion forums, and has been developed by DTA Wales to help with the management of community buildings. These are the Technical level set of resources.
Learner Level: Intermediate. This guide will provide guidance for energy use of different lighting types, and how installing LED lighting and PIR detectors can reduce energy bills.
Learner Level: Intermediate. Buildings need to be ventilated if they are to be healthy and usable spaces. Keeping ventilation in mind is especially important when making changes (such as increased insulation) to help with energy efficiency.
Learner Level: Intermediate. Moisture in buildings is often a prevalent and persistent problem. This guide provides an understanding of the situation along with some of the solutions.
Learner Level: Intermediate. You may be interested in a solar array, or maybe solar plus battery storage. What size array? And what size battery? This guide will help you work out what size solar array will work best for your building.
