Objectives

To be able to:

2.1 State features of a building that improve efficiency2.2 State the importance of waste management


3

Sustainable Construction

Local planning authorities now legally require that all building development is designed to incorporate appropriate climate change mitigation measures such as sustainable drainage systems, water efficiency, flood risk management, and the use of recycled materials in new development.

This is due to the global concern about finite renewable resources and the positive impact construction now needs to make on the environment.


4

Examples of Sustainable Construction

Sustainability can be incorporated in construction projects by using:

• Locally sourced and environmentally-friendly building materials and products (eg timber)

• Alternative building methods (such as timber framing)

• Alternative energy features (wind, solar, water-harvesting)

• Energy saving and heat loss prevention measures (insulation, draught control, double glazing, low energy lighting)

• Low impact construction methods (incorporating high levels of reuse and recycling)


5

Features of a building that improve efficiency by reducing the consumption of energy:

Solar Panels

Ground Source Heat Pump

Double and Triple Glazing

Domestic &Commercial Property Wind Turbines


6

Features of a building that improve efficiency by reducing the consumption of energy and water:

Insulation Rainwater Harvesting

Waste is:

• Any unwanted surplus from the construction process

and

• Any article which needs to be disposed of because it is broken, worn out, contaminated or otherwise spoiled.


9

Waste Control Procedures

1. Before surplus materials are disposed of, they must first be inspected for potential onsite reuse or recycling.

2. Only when this has been done, should disposal be considered.

3. Waste for disposal should be separated into different skips so that the waste facility they are taken to can more efficiently process valuable recyclable materials such as:

Brick, rubble, cement, plaster and plasterboard

Timber, cardboard, paper

Scrap metal, pipe, wire

uPVC window mouldings, gutters and down pipes.

The importance of waste management

• Safety: the regular collection, grading and sorting of waste contributes to good housekeeping practices and so a safer working environment.

• Financial Implications: as well as contributing to environmental protection, onsite reuse and recycling along with careful and directed waste disposal cuts down operating costs and so increases potential profit.

• Legal and Contractual Obligations: as well as planning authority requirements (slide 3), customers are increasingly choosing building firms that can prove they promote sustainability in their practices.
